Gunnar Wolf: After miniDebConf Santa Fe

Last week we held our promised miniDebConf in Santa Fe City, Santa Fe province, Argentina just across the river from Paran , where I have spent almost six beautiful months I will never forget. Around 500 Kilometers North from Buenos Aires, Santa Fe and Paran are separated by the beautiful and majestic Paran river, which flows from Brazil, marks the Eastern border of Paraguay, and continues within Argentina as the heart of the litoral region of the country, until it merges with the Uruguay river (you guessed right the river marking the Eastern border of Argentina, first with Brazil and then with Uruguay), and they become the R o de la Plata. This was a short miniDebConf: we were lent the APUL union s building for the weekend (thank you very much!); during Saturday, we had a cycle of talks, and on sunday we had more of a hacklab logic, having some unstructured time to work each on their own projects, and to talk and have a good time together. We were five Debian people attending: santiago debacle eamanu dererk gwolf @debian.org. My main contact to kickstart organization was Mart n Bayo. Mart n was for many years the leader of the Technical Degree on Free Software at Universidad Nacional del Litoral, where I was also a teacher for several years. Together with Leo Mart nez, also a teacher at the tecnicatura, they contacted us with Guillermo and Gabriela, from the APUL non-teaching-staff union of said university. We had the following set of talks (for which there is a promise to get electronic record, as APUL was kind enough to record them! of course, I will push them to our usual conference video archiving service as soon as I get them)

Dirk Eddelbuettel: dtts 0.1.2 on CRAN: Maintenance

Leonardo and I are happy to announce the release of a very minor maintenance release 0.1.2 of our dtts package which has been on CRAN for a little under two years now. dtts builds upon our nanotime package as well as the beloved data.table to bring high-performance and high-resolution indexing at the nanosecond level to data frames. dtts aims to offers the time-series indexing versatility of xts (and zoo) to the immense power of data.table while supporting highest nanosecond resolution. This release follows yesterday s long-awaited release of data.table version 1.5.0 which had been some time in the making as the first new major.minor release since Matt drifted into being less active and the forefront. The release also renamed the one C-level API accessor to data.table (which was added, if memory serves, by Leonardo with our use in mind). So we have to catch up to the renamed identifier; this release does that, and adds a versioned imports statement on data.table. The short list of changes follows.

Changes in version 0.1.2 (2024-01-31)
  • Update the one exported C-level identifier from data.table following its 1.5.0 release and a renaming
  • Routine continuous integration updates

Courtesy of my CRANberries, there is also a report with diffstat for this release. Questions, comments, issue tickets can be brought to the GitHub repo. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Russ Allbery: Review: The Cassini Division

Review: The Cassini Division, by Ken MacLeod
Series: Fall Revolution #3
Publisher: Tor
Copyright: 1998
Printing: August 2000
ISBN: 0-8125-6858-3
Format: Mass market
Pages: 305
The Cassini Division is the third book in the Fall Revolution series and a fairly direct sequel (albeit with different protagonists) to The Stone Canal. This is not a good place to start the series. It's impossible to talk about the plot of this book without discussing the future history of this series, which arguably includes some spoilers for The Star Fraction and The Stone Canal. I don't think the direction of history matters that much in enjoying the previous books, but read the first two books of the series before this review if you want to avoid all spoilers. When the Outwarders uploaded themselves and went fast, they did a lot of strange things: an interstellar probe contrary to all known laws of physics, the disassembly of Ganymede, and the Malley Mile, which plays a significant role in The Stone Canal. They also crashed the Earth. This was not entirely their fault. There were a lot of politics, religious fundamentalism, and plagues in play as well. But the storm of viruses broadcast from their transformed Jupiter shut down essentially all computing equipment on Earth, which set off much of the chaos. The results were catastrophic, and also politically transformative. Now, the Solar Union is a nearly unified anarchosocialist society, with only scattered enclaves of non-cooperators left outside that structure. Ellen May Ngewthu is a leader of the Cassini Division, the bulwark that stands between humans and the Outwarders. The Division ruthlessly destroys any remnant or probe that dares rise out of Jupiter's atmosphere, ensuring that the Outwarders, whatever they have become after untold generations of fast evolution, stay isolated to the one planet they have absorbed. The Division is very good at what they do. But there is a potential gap in that line of defense: there are fast folk in storage at the other end of the Malley Mile, on New Mars, and who knows what the deranged capitalists there will do or what forces they might unleash. The one person who knows a path through the Malley Mile isn't talking, so Ellen goes in search of the next best thing: the non-cooperator scientist Isambard Kingdom Malley. I am now thoroughly annoyed at how politics are handled in this series, and much less confused by the frequency with which MacLeod won Prometheus Awards from the Libertarian Futurist Society. Some of this is my own fault for having too high of hopes for political SF, but nothing in this series so far has convinced me that MacLeod is seriously engaging with political systems. Instead, the world-building to date makes the classic libertarian mistake of thinking societies will happily abandon stability and predictability in favor of their strange definition of freedom. The Solar Union is based on what Ellen calls the true knowledge, which is worth quoting in full so that you know what kind of politics we're talking about:
Life is a process of breaking down and using other matter, and if need be, other life. Therefore, life is aggression, and successful life is successful aggression. Life is the scum of matter, and people are the scum of life. There is nothing but matter, forces, space and time, which together make power. Nothing matters, except what matters to you. Might makes right, and power makes freedom. You are free to do whatever is in your power, and if you want to survive and thrive you had better do whatever is in your interests. If your interests conflict with those of others, let the others pit their power against yours, everyone for theirselves. If your interests coincide with those of others, let them work together with you, and against the rest. We are what we eat, and we eat everything. All that you really value, and the goodness and truth and beauty of life, have their roots in this apparently barren soil. This is the true knowledge. We had founded our idealism on the most nihilistic implications of science, our socialism on crass self-interest, our peace on our capacity for mutual destruction, and our liberty on determinism. We had replaced morality with convention, bravery with safety, frugality with plenty, philosophy with science, stoicism with anaesthetics and piety with immortality. The universal acid of the true knowledge had burned away a world of words, and exposed a universe of things. Things we could use.
This is certainly something that some people will believe, particularly cynical college students who love political theory, feeling smarter than other people, and calling their pet theories things like "the true knowledge." It is not even remotely believable as the governing philosophy of a solar confederation. The point of government for the average person in human society is to create and enforce predictable mutual rules that one can use as a basis for planning and habits, allowing you to not think about politics all the time. People who adore thinking about politics have great difficulty understanding how important it is to everyone else to have ignorable government. Constantly testing your power against other coalitions is a sport, not a governing philosophy. Given the implication that this testing is through violence or the threat of violence, it beggars belief that any large number of people would tolerate that type of instability for an extended period of time. Ellen is fully committed to the true knowledge. MacLeod likely is not; I don't think this represents the philosophy of the author. But the primary political conflict in this novel famous for being political science fiction is between the above variation of anarchy and an anarchocapitalist society, neither of which are believable as stable political systems for large numbers of people. This is a bit like seeking out a series because you were told it was about a great clash of European monarchies and discovering it was about a fight between Liberland and Sealand. It becomes hard to take the rest of the book seriously. I do realize that one point of political science fiction is to play with strange political ideas, similar to how science fiction plays with often-implausible science ideas. But those ideas need some contact with human nature. If you're going to tell me that the key to clawing society back from a world-wide catastrophic descent into chaos is to discard literally every social system used to create predictability and order, you had better be describing aliens, because that's not how humans work. The rest of the book is better. I am untangling a lot of backstory for the above synopsis, which in the book comes in dribs and drabs, but piecing that together is good fun. The plot is far more straightforward than the previous two books in the series: there is a clear enemy, a clear goal, and Ellen goes from point A to point B in a comprehensible way with enough twists to keep it interesting. The core moral conflict of the book is that Ellen is an anti-AI fanatic to the point that she considers anyone other than non-uploaded humans to be an existential threat. MacLeod gives the reader both reasons to believe Ellen is right and reasons to believe she's wrong, which maintains an interesting moral tension. One thing that MacLeod is very good at is what Bob Shaw called "wee thinky bits." I think my favorite in this book is the computer technology used by the Cassini Division, who have spent a century in close combat with inimical AI capable of infecting any digital computer system with tailored viruses. As a result, their computers are mechanical non-Von-Neumann machines, but mechanical with all the technology of a highly-advanced 24th century civilization with nanometer-scale manufacturing technology. It's a great mental image and a lot of fun to think about. This is the only science fiction novel that I can think of that has a hard-takeoff singularity that nonetheless is successfully resisted and fought to a stand-still by unmodified humanity. Most writers who were interested in the singularity idea treated it as either a near-total transformation leaving only remnants or as something that had to be stopped before it started. MacLeod realizes that there's no reason to believe a post-singularity form of life would be either uniform in intent or free from its own baffling sudden collapses and reversals, which can be exploited by humans. It makes for a much better story. The sociology of this book is difficult to swallow, but the characterization is significantly better than the previous books of the series and the plot is much tighter. I was too annoyed by the political science to fully enjoy it, but that may be partly the fault of my expectations coming in. If you like chewy, idea-filled science fiction with a lot of unexplained world-building that you have to puzzle out as you go, you may enjoy this, although unfortunately I think you need to read at least The Stone Canal first. The ending was a bit unsatisfying, but even that includes some neat science fiction ideas. Followed by The Sky Road, although I understand it is not a straightforward sequel. Rating: 6 out of 10

Antoine Beaupr : OpenPGP key transition

This is a short announcement to say that I have changed my main OpenPGP key. A signed statement is available with the cryptographic details but, in short, the reason is that I stopped using my old YubiKey NEO that I have worn on my keyring since 2015. I now have a YubiKey 5 which supports ED25519 which features much shorter keys and faster decryption. It allowed me to move all my secret subkeys on the key (including encryption keys) while retaining reasonable performance. I have written extensive documentation on how to do that OpenPGP key rotation and also YubiKey OpenPGP operations.

Warning on storing encryption keys on a YubiKey People wishing to move their private encryption keys to such a security token should be very careful as there are special precautions to take for disaster recovery. I am toying with the idea of writing an article specifically about disaster recovery for secrets and backups, dealing specifically with cases of death or disabilities.

Autocrypt changes One nice change is the impact on Autocrypt headers, which are considerably shorter. Before, the header didn't even fit on a single line in an email, it overflowed to five lines:

Note that I have implemented my own kind of ridiculous Autocrypt support for the Notmuch Emacs email client I use, see this elisp code. To import keys, I pipe the message into this script which is basically just:
sq autocrypt decode   gpg --import
... thanks to Sequoia best-of-class Autocrypt support.

Note on OpenPGP usage While some have claimed OpenPGP's death, I believe those are overstated. Maybe it's just me, but I still use OpenPGP for my password management, to authenticate users and messages, and it's the interface to my YubiKey for authenticating with SSH servers. I understand people feel that OpenPGP is possibly insecure, counter-intuitive and full of problems, but I think most of those problems should instead be attributed to its current flagship implementation, GnuPG. I have tried to work with GnuPG for years, and it keeps surprising me with evilness and oddities. I have high hopes that the Sequoia project can bring some sanity into this space, and I also hope that RFC4880bis can eventually get somewhere so we have a more solid specification with more robust crypto. It's kind of a shame that this has dragged on for so long, but Update: there's a separate draft called openpgp-crypto-refresh that might actually be adopted as the "OpenPGP RFC" soon! And it doesn't keep real work from happening in Sequoia and other implementations. Thunderbird rewrote their OpenPGP implementation with RNP (which was, granted, a bumpy road because it lost compatibility with GnuPG) and Sequoia now has a certificate store with trust management (but still no secret storage), preliminary OpenPGP card support and even a basic GnuPG compatibility layer. I'm also curious to try out the OpenPGP CA capabilities. So maybe it's just because I'm becoming an old fart that doesn't want to change tools, but so far I haven't seen a good incentive in switching away from OpenPGP, and haven't found a good set of tools that completely replace it. Maybe OpenSSH's keys and CA can eventually replace it, but I suspect they will end up rebuilding most of OpenPGP anyway, just more slowly. If they do, let's hope they avoid the mistakes our community has done in the past at least...

Dirk Eddelbuettel: dtts 0.1.1 on CRAN: Enhancements

Leonardo and I are happy to announce the release of a first follow-up release 0.1.1 of our dtts package which got to [CRAN][cran] in its initial upload last year. dtts builds upon our nanotime package as well as the beloved data.table to bring high-performance and high-resolution indexing at the nanosecond level to data frames. dtts aims to bring the time-series indexing versatility of xts (and zoo) to the immense power of data.table while supporting highest nanosecond resolution. This release fixes a bug flagged by valgrind and brings several internal enhancements.

Changes in version 0.1.1 (2023-08-08)
  • A simplifcation was applied to the C++ interface glue code (#9 fixing #8)
  • The package no longer enforces the C++11 compilation standard (#10)
  • An uninitialized memory read has been correct (#11)
  • A new function ops has been added (#12)
  • Function names no longer start with a dot (#13)
  • Arbitrary index columns are now supported (#13)

Courtesy of my CRANberries, there is also a diffstat report for the this release this release. Questions, comments, issue tickets can be brought to the GitHub repo. If you like this or other open-source work I do, you can now sponsor me at GitHub.

Gunnar Wolf: Road trip through mountain ridges to find the surreal

We took a couple of days of for a family vacation / road trip through the hills of Central Mexico. The overall trip does not look like anything out of the ordinary Other than the fact that Google forecasted we d take approximately 15.5 hours driving for 852Km that is, an average of almost 55 Km/h. And yes, that s what we signed up for. And that s what we got. Of course, the exact routes are not exactly what Google suggested (I can say we optimized a bit the route, i.e., by avoiding the metropolitan area of Quer taro, at the extreme west, and going via San Juan del R o / Tequisquiapan / Bernal). The first stretch of the road is just a regular, huge highway, with no particular insights. The highways leaving and entering Mexico City on the North are not fun nor beautiful, only they are needed to get nice trips going Mexico City sits at a point of changing climates. Of course, it is a huge city And I cannot imagine how it would be without all of the urbanization it now sports. But anyway: On the West, South, and part of the East, it is surrounded by high mountains, with beautiful and dense forests. Mexico City is 2200m high, and most of the valley s surrounding peaks are ~3000m (and at the South Eastern tip, our two big volcanoes, Popocat petl and Iztacc huatl, get past the 5700m mark). Towards the North, the landscape is flatter and much more dry. Industrial compounds give way to dry grasslands. Of course, central Mexico does not understand the true meaning of flat, and the landscape is full with eh-not-very-big mountains. Then, as we entered Quer taro State, we started approaching Bernal. And we saw a huge rock that looks like it is not supposed to be there! It just does not fit the surroundings. Shortly after Bernal, we entered a beautiful, although most crumpled, mountain ridge: Sierra Gorda de Quer taro. Sierra Gorda encompasses most of the North of the (quite small 11500Km total) state of Quer taro, plus portions of the neighboring states; other than the very abrupt and sharp orography, what strikes me most is the habitat diversity it encompasses. We started going up an absolute desert, harsh and beautiful; we didn t take pictures along the way as the road is difficult enough that there are almost no points for stopping for refreshments or for photo opportunities. But it is quite majestic. And if you think deserts are barren, boring places well, please do spend some time enjoying them! Anyway At on point, the road passes by a ~3100m height, and suddenly Pines! More pines! A beautiful forest! We reached our first stop at the originally mining town of Pinal de Amoles. After spending the night there and getting a much needed rest, we started a quite steep descent towards Jalpan de Serra. While it is only ~20Km away on the map, we descended from 2300 to 760 meters of altitude (and the road was over 40Km long). Being much lower, the climate drastically changed from cool and humid to quite warm and the body attitude in the kids does not lie! In the mid-18th century, Fray Jun pero Serra established five missions to evangelize the population of this very harsh territory, and the frontispiece for the church and monastery in Jalpan is quite breathtaking. But we were just passing by Jalpan. A short visit to the church and to the ice-cream shop, and we were again on our way. We crossed the state border, entering San Luis Potos , and arrived to our main destination: Xilitla, the little town in the beautiful Huasteca where the jungle meets surrealism. Xilitla was chosen by the British poet and patron of various surrealist artists https://en.wikipedia.org/wiki/Edward_James. He was a British noble (an unofficial grandson of King Edward VII), and heir to a huge fortune. I m not going to repeat here his very well known biography suffice to say that he got in love with the Huasteca, and bought a >30ha piece of jungle and mountain close to the Xilitla town, and made it his house. With very ample economic resources, in the late 1940s he started his lifelong project of building a surrealist garden. And Well, that s enough blabbering for me. I m sharing some pictures I took there. The place is plainly magic and wonderful. Edward James died in 1984, and his will decrees that after his death, the jungle should be allowed to reclaim the constructions so many structures are somewhat crumbling, and it is expected they will break down in the following decades. But for whoever comes to Mexico This magic place is definitely worth the heavy ride to the middle of the mountains and to the middle of the jungle. Xilitla now also hosts a very good museum with sculptures by Leonora Carrington, James long-time friend, but I m not going to abuse this space with even more pictures. And of course, we did more, and enjoyed more, during our three days in Xilitla. And for our way back I wanted to try a different route. We decided to come back to Mexico City crossing Hidalgo state instead of Quer taro. I had feared the roads would be in a worse shape or would be more difficult to travel And I was happy to be proven wrong! This was the longest driving stretch approximately 6:30 for 250Km. The roads are in quite decent shape, and while there are some stretches where we were quite lonely (probably the loneliest one was the sharp ascent from Tamazunchale to the detour before Orizatl n), the road felt safe and well kept at all times. The sights all across Eastern Hidalgo are breathtaking, and all furiously green (be it with really huge fern leaves or with tall, strong pines), until Zacualtip n. And just as abruptly or more as when we entered Pinal de Amoles We crossed Orizatl n, and we were in a breathtaking arid, desert-like environment again. We crossed the Barranca de Metztitl n natural reserve, and arrived to spend the night at Huasca de Ocampo. There are many more things we could have done starting at Huasca, a region where old haciendas thrived, full of natural formations, and very very interesting. But we were tired and pining to be finally back home. So we rested until mid-morning and left straight back home in Mexico City. Three hours later, we were relaxing, preparing lunch, the kids watching whatever-TV-like-things are called nowadays. All in all, a very beautiful vacation!

Reproducible Builds: Reproducible Builds in May 2023

Welcome to the May 2023 report from the Reproducible Builds project In our reports, we outline the most important things that we have been up to over the past month. As always, if you are interested in contributing to the project, please visit our Contribute page on our website.


Holger Levsen gave a talk at the 2023 edition of the Debian Reunion Hamburg, a semi-informal meetup of Debian-related people in northern Germany. The slides are available online.
In April, Holger Levsen gave a talk at foss-north 2023 titled Reproducible Builds, the first ten years. Last month, however, Holger s talk was covered in a round-up of the conference on the Free Software Foundation Europe (FSFE) blog.
Pronnoy Goswami, Saksham Gupta, Zhiyuan Li, Na Meng and Daphne Yao from Virginia Tech published a paper investigating the Reproducibility of NPM Packages. The abstract includes:
When using open-source NPM packages, most developers download prebuilt packages on npmjs.com instead of building those packages from available source, and implicitly trust the downloaded packages. However, it is unknown whether the blindly trusted prebuilt NPM packages are reproducible (i.e., whether there is always a verifiable path from source code to any published NPM package). [ ] We downloaded versions/releases of 226 most popularly used NPM packages and then built each version with the available source on GitHub. Next, we applied a differencing tool to compare the versions we built against versions downloaded from NPM, and further inspected any reported difference.
The paper reports that among the 3,390 versions of the 226 packages, only 2,087 versions are reproducible, and furthermore that multiple factors contribute to the non-reproducibility including flexible versioning information in package.json file and the divergent behaviors between distinct versions of tools used in the build process. The paper concludes with insights for future verifiable build procedures. Unfortunately, a PDF is not available publically yet, but a Digital Object Identifier (DOI) is available on the paper s IEEE page.
Elsewhere in academia, Betul Gokkaya, Leonardo Aniello and Basel Halak of the School of Electronics and Computer Science at the University of Southampton published a new paper containing a broad overview of attacks and comprehensive risk assessment for software supply chain security. Their paper, titled Software supply chain: review of attacks, risk assessment strategies and security controls, analyses the most common software supply-chain attacks by providing the latest trend of analyzed attack, and identifies the security risks for open-source and third-party software supply chains. Furthermore, their study introduces unique security controls to mitigate analyzed cyber-attacks and risks by linking them with real-life security incidence and attacks . (arXiv.org, PDF)
NixOS is now tracking two new reports at reproducible.nixos.org. Aside from the collection of build-time dependencies of the minimal and Gnome installation ISOs, this page now also contains reports that are restricted to the artifacts that make it into the image. The minimal ISO is currently reproducible except for Python 3.10, which hopefully will be resolved with the coming update to Python version 3.11.
On our rb-general mailing list this month: David A. Wheeler started a thread noting that the OSSGadget project s oss-reproducible tool was measuring something related to but not the same as reproducible builds. Initially they had adopted the term semantically reproducible build term for what it measured, which they defined as being if its build results can be either recreated exactly (a bit for bit reproducible build), or if the differences between the release package and a rebuilt package are not expected to produce functional differences in normal cases. This generated a significant number of replies, and several were concerned that people might confuse what they were measuring with reproducible builds . After discussion, the OSSGadget developers decided to switch to the term semantically equivalent for what they measured in order to reduce the risk of confusion. Vagrant Cascadian (vagrantc) posted an update about GCC, binutils, and Debian s build-essential set with some progress, some hope, and I daresay, some fears . Lastly, kpcyrd asked a question about building a reproducible Linux kernel package for Arch Linux (answered by Arnout Engelen). In the same, thread David A. Wheeler pointed out that the Linux Kernel documentation has a chapter about Reproducible kernel builds now as well.
In Debian this month, nine reviews of Debian packages were added, 20 were updated and 6 were removed this month, all adding to our knowledge about identified issues. In addition, Vagrant Cascadian added a link to the source code causing various ecbuild issues. [ ]
The F-Droid project updated its Inclusion How-To with a new section explaining why it considers reproducible builds to be best practice and hopes developers will support the team s efforts to make as many (new) apps reproducible as it reasonably can.
In diffoscope development this month, version 242 was uploaded to Debian unstable by Chris Lamb who also made the following changes: In addition, Mattia Rizzolo documented how to (re)-produce a binary blob in the code [ ] and Vagrant Cascadian updated the version of diffoscope in GNU Guix to 242 [ ].
reprotest is our tool for building the same source code twice in different environments and then checking the binaries produced by each build for any differences. This month, Holger Levsen uploaded versions 0.7.24 and 0.7.25 to Debian unstable which added support for Tox versions 3 and 4 with help from Vagrant Cascadian [ ][ ][ ]

Upstream patches The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of such patches, including: In addition, Jason A. Donenfeld filed a bug (now fixed in the latest alpha version) in the Android issue tracker to report that generateLocaleConfig in Android Gradle Plugin version 8.1.0 generates XML files using non-deterministic ordering, breaking reproducible builds. [ ]

Testing framework The Reproducible Builds project operates a comprehensive testing framework (available at tests.reproducible-builds.org) in order to check packages and other artifacts for reproducibility. In May, a number of changes were made by Holger Levsen:
  • Update the kernel configuration of arm64 nodes only put required modules in the initrd to save space in the /boot partition. [ ]
  • A huge number of changes to a new tool to document/track Jenkins node maintenance, including adding --fetch, --help, --no-future and --verbose options [ ][ ][ ][ ] as well as adding a suite of new actions, such as apt-upgrade, command, deploy-git, rmstamp, etc. [ ][ ][ ][ ] in addition a significant amount of refactoring [ ][ ][ ][ ].
  • Issue warnings if apt has updates to install. [ ]
  • Allow Jenkins to run apt get update in maintenance job. [ ]
  • Installed bind9-dnsutils on some Ubuntu 18.04 nodes. [ ][ ]
  • Fixed the Jenkins shell monitor to correctly deal with little-used directories. [ ]
  • Updated the node health check to warn when apt upgrades are available. [ ]
  • Performed some node maintenance. [ ]
In addition, Vagrant Cascadian added the nocheck, nopgo and nolto when building gcc-* and binutils packages [ ] as well as performed some node maintenance [ ][ ]. In addition, Roland Clobus updated the openQA configuration to specify longer timeouts and access to the developer mode [ ] and updated the URL used for reproducible Debian Live images [ ].

Russ Allbery: Review: The Stone Canal

Review: The Stone Canal, by Ken MacLeod
Series: Fall Revolution #2
Publisher: Tor
Copyright: 1996
Printing: January 2001
ISBN: 0-8125-6864-8
Format: Mass market
Pages: 339
The Stone Canal is a sort of halfway sequel to The Star Fraction. They both take place in the same universe, but the characters are almost entirely disjoint. Half of The Stone Canal happens (mostly) well before the previous book and the other half happens well after it. This book does contain spoilers for the ending of The Star Fraction if one connects the events of the two books correctly (which was a bit harder than I thought it should be), so I would not read them out of order. At the start of The Stone Canal, Jon Wilde wakes up on New Mars beside the titular canal, in the middle of nowhere, accompanied only by a robot that says it made him. Wilde remembers dying on Earth; this new life is apparently some type of resurrection. It's a long walk to Ship City, the center of civilization of a place the robot tells him is New Mars. In Ship City, an android named Dee Model has escaped from her owner and is hiding in a bar. There, she meets an AI abolitionist named Tamara, who helps her flee out the back and down the canal on a boat when Wilde walks into the bar and immediately recognizes her. The abolitionists provide her protection and legal assistance to argue her case for freedom from her owner, a man named Reid. The third thread of the story, and about half the book, is Jon Wilde's life on Earth, starting in 1975 and leading up to the chaotic wars, political fracturing, and revolutions that formed the background and plot of The Star Fraction. Eventually that story turns into a full-fledged science fiction setting, but not until the last 60 pages of the book. I successfully read two books in a Ken MacLeod series! Sadly, I'm not sure I enjoyed the experience. I commented in my review of The Star Fraction that the appeal for me in MacLeod's writing was his reputation as a writer of political science fiction. Unfortunately that's been a bust. The characters are certainly political, in the sense that they profess to have strong political viewpoints and are usually members of some radical (often Trotskyite) organization. There are libertarian anarchist societies and lots of political conflict. But there is almost no meaningful political discussion in any of these books so far. The politics are all tactical or background, and often seem to be created by authorial fiat. For example, New Mars is a sort of libertarian anarchy that somehow doesn't have corporations or a strongman ruler, even though the history (when we finally learn it) would have naturally given rise to one or the other (and has, in numerous other SF novels with similar plots). There's a half-assed explanation for this towards the end of the book that I didn't find remotely believable. Another part of the book describes the formation of the libertarian microstate in The Star Fraction, but never answers a "why" or "how" question I had in the previous book in a satisfying way. Somehow people stop caring about control or predictability or stability or traditional hierarchy without any significant difficulties except external threats, in situations of chaos and disorder where historically humans turn to anyone promising firm structure. It's common to joke about MacLeod winning multiple libertarian Prometheus Awards for his fiction despite being a Scottish communist. I'm finding that much less surprising now that I've read more of his books. Whether or not he believes in it himself, he's got the cynical libertarian smugness and hand-waving down pat. What his characters do care deeply about is smoking, drinking, and having casual sex. (There's more political fire here around opposition to anti-smoking laws than there is about any of the society-changing political structures that somehow fall into place.) I have no objections to any of those activities from a moral standpoint, but reading about other people doing them is a snoozefest. The flashback scenes sketch out enough imagined history to satisfy some curiosity from the previous book, but they're mostly about the world's least interesting love triangle, involving two completely unlikable men and lots of tedious jealousy and posturing. The characters in The Stone Canal are, in general, a problem. One of those unlikable men is Wilde, the protagonist for most of the book. Not only did I never warm to him, I never figured out what motivates him or what he cares about. He's a supposedly highly political person who seems to engage in politics with all the enthusiasm of someone filling out tax forms, and is entirely uninterested in explaining to the reader any sort of coherent philosophical approach. The most interesting characters in this book are the women (Annette, Dee Model, Tamara, and, very late in the book, Meg), but other than Dee Model they rarely get much focus from the story. By far the best part of this book is the last 60 pages, where MacLeod finally explains the critical bridge events between Wilde's political history on earth and the New Mars society. I thought this was engrossing, fast-moving, and full of interesting ideas (at least for a 1990s book; many of them feel a bit stale now, 25 years later). It was also frustrating, because this was the book I wanted to have been reading for the previous 270 pages, instead of MacLeod playing coy with his invented history or showing us interminable scenes about Wilde's insecure jealousy over his wife. It's also the sort of book where at one point characters (apparently uniformly male as far as one could tell from the text of the book) get assigned sex slaves, and while MacLeod clearly doesn't approve of this, the plot is reminiscent of a Heinlein novel: the protagonist's sex slave becomes a very loyal permanent female companion who seems to have the same upside for the male character in question. This was unfortunately not the book I was hoping for. I did enjoy the last hundred pages, and it's somewhat satisfying to have the history come together after puzzling over what happened for 200 pages. But I found the characters tedious and annoying and the politics weirdly devoid of anything like sociology, philosophy, or political science. There is the core of a decent 1990s AI and singularity novel here, but the technology is now rather dated and a lot of other people have tackled the same idea with fewer irritating ticks. Not recommended, although I'll probably continue to The Cassini Division because the ending was a pretty great hook for another book. Followed by The Cassini Division. Rating: 5 out of 10

Arturo Borrero Gonz lez: Kubecon and CloudNativeCon 2023 Europe summary

Post logo This post serves as a report from my attendance to Kubecon and CloudNativeCon 2023 Europe that took place in Amsterdam in April 2023. It was my second time physically attending this conference, the first one was in Austin, Texas (USA) in 2017. I also attended once in a virtual fashion. The content here is mostly generated for the sake of my own recollection and learnings, and is written from the notes I took during the event. The very first session was the opening keynote, which reunited the whole crowd to bootstrap the event and share the excitement about the days ahead. Some astonishing numbers were announced: there were more than 10.000 people attending, and apparently it could confidently be said that it was the largest open source technology conference taking place in Europe in recent times. It was also communicated that the next couple iteration of the event will be run in China in September 2023 and Paris in March 2024. More numbers, the CNCF was hosting about 159 projects, involving 1300 maintainers and about 200.000 contributors. The cloud-native community is ever-increasing, and there seems to be a strong trend in the industry for cloud-native technology adoption and all-things related to PaaS and IaaS. The event program had different tracks, and in each one there was an interesting mix of low-level and higher level talks for a variety of audience. On many occasions I found that reading the talk title alone was not enough to know in advance if a talk was a 101 kind of thing or for experienced engineers. But unlike in previous editions, I didn t have the feeling that the purpose of the conference was to try selling me anything. Obviously, speakers would make sure to mention, or highlight in a subtle way, the involvement of a given company in a given solution or piece of the ecosystem. But it was non-invasive and fair enough for me. On a different note, I found the breakout rooms to be often small. I think there were only a couple of rooms that could accommodate more than 500 people, which is a fairly small allowance for 10k attendees. I realized with frustration that the more interesting talks were immediately fully booked, with people waiting in line some 45 minutes before the session time. Because of this, I missed a few important sessions that I ll hopefully watch online later. Finally, on a more technical side, I ve learned many things, that instead of grouping by session I ll group by topic, given how some subjects were mentioned in several talks. On gitops and CI/CD pipelines Most of the mentions went to FluxCD and ArgoCD. At that point there were no doubts that gitops was a mature approach and both flux and argoCD could do an excellent job. ArgoCD seemed a bit more over-engineered to be a more general purpose CD pipeline, and flux felt a bit more tailored for simpler gitops setups. I discovered that both have nice web user interfaces that I wasn t previously familiar with. However, in two different talks I got the impression that the initial setup of them was simple, but migrating your current workflow to gitops could result in a bumpy ride. This is, the challenge is not deploying flux/argo itself, but moving everything into a state that both humans and flux/argo can understand. I also saw some curious mentions to the config drifts that can happen in some cases, even if the goal of gitops is precisely for that to never happen. Such mentions were usually accompanied by some hints on how to operate the situation by hand. Worth mentioning, I missed any practical information about one of the key pieces to this whole gitops story: building container images. Most of the showcased scenarios were using pre-built container images, so in that sense they were simple. Building and pushing to an image registry is one of the two key points we would need to solve in Toolforge Kubernetes if adopting gitops. In general, even if gitops were already in our radar for Toolforge Kubernetes, I think it climbed a few steps in my priority list after the conference. Another learning was this site: https://opengitops.dev/. Group On etcd, performance and resource management I attended a talk focused on etcd performance tuning that was very encouraging. They were basically talking about the exact same problems we have had in Toolforge Kubernetes, like api-server and etcd failure modes, and how sensitive etcd is to disk latency, IO pressure and network throughput. Even though Toolforge Kubernetes scale is small compared to other Kubernetes deployments out there, I found it very interesting to see other s approaches to the same set of challenges. I learned how most Kubernetes components and apps can overload the api-server. Because even the api-server talks to itself. Simple things like kubectl may have a completely different impact on the API depending on usage, for example when listing the whole list of objects (very expensive) vs a single object. The conclusion was to try avoiding hitting the api-server with LIST calls, and use ResourceVersion which avoids full-dumps from etcd (which, by the way, is the default when using bare kubectl get calls). I already knew some of this, and for example the jobs-framework-emailer was already making use of this ResourceVersion functionality. There have been a lot of improvements in the performance side of Kubernetes in recent times, or more specifically, in how resources are managed and used by the system. I saw a review of resource management from the perspective of the container runtime and kubelet, and plans to support fancy things like topology-aware scheduling decisions and dynamic resource claims (changing the pod resource claims without re-defining/re-starting the pods). On cluster management, bootstrapping and multi-tenancy I attended a couple of talks that mentioned kubeadm, and one in particular was from the maintainers themselves. This was of interest to me because as of today we use it for Toolforge. They shared all the latest developments and improvements, and the plans and roadmap for the future, with a special mention to something they called kubeadm operator , apparently capable of auto-upgrading the cluster, auto-renewing certificates and such. I also saw a comparison between the different cluster bootstrappers, which to me confirmed that kubeadm was the best, from the point of view of being a well established and well-known workflow, plus having a very active contributor base. The kubeadm developers invited the audience to submit feature requests, so I did. The different talks confirmed that the basic unit for multi-tenancy in kubernetes is the namespace. Any serious multi-tenant usage should leverage this. There were some ongoing conversations, in official sessions and in the hallway, about the right tool to implement K8s-whitin-K8s, and vcluster was mentioned enough times for me to be convinced it was the right candidate. This was despite of my impression that multiclusters / multicloud are regarded as hard topics in the general community. I definitely would like to play with it sometime down the road. On networking I attended a couple of basic sessions that served really well to understand how Kubernetes instrumented the network to achieve its goal. The conference program had sessions to cover topics ranging from network debugging recommendations, CNI implementations, to IPv6 support. Also, one of the keynote sessions had a reference to how kube-proxy is not able to perform NAT for SIP connections, which is interesting because I believe Netfilter Conntrack could do it if properly configured. One of the conclusions on the CNI front was that Calico has a massive community adoption (in Netfilter mode), which is reassuring, especially considering it is the one we use for Toolforge Kubernetes. Slide On jobs I attended a couple of talks that were related to HPC/grid-like usages of Kubernetes. I was truly impressed by some folks out there who were using Kubernetes Jobs on massive scales, such as to train machine learning models and other fancy AI projects. It is acknowledged in the community that the early implementation of things like Jobs and CronJobs had some limitations that are now gone, or at least greatly improved. Some new functionalities have been added as well. Indexed Jobs, for example, enables each Job to have a number (index) and process a chunk of a larger batch of data based on that index. It would allow for full grid-like features like sequential (or again, indexed) processing, coordination between Job and more graceful Job restarts. My first reaction was: Is that something we would like to enable in Toolforge Jobs Framework? On policy and security A surprisingly good amount of sessions covered interesting topics related to policy and security. It was nice to learn two realities:
  1. kubernetes is capable of doing pretty much anything security-wise and create greatly secured environments.
  2. it does not by default. The defaults are not security-strict on purpose.
It kind of made sense to me: Kubernetes was used for a wide range of use cases, and developers didn t know beforehand to which particular setup they should accommodate the default security levels. One session in particular covered the most basic security features that should be enabled for any Kubernetes system that would get exposed to random end users. In my opinion, the Toolforge Kubernetes setup was already doing a good job in that regard. To my joy, some sessions referred to the Pod Security Admission mechanism, which is one of the key security features we re about to adopt (when migrating away from Pod Security Policy). I also learned a bit more about Secret resources, their current implementation and how to leverage a combo of CSI and RBAC for a more secure usage of external secrets. Finally, one of the major takeaways from the conference was learning about kyverno and kubeaudit. I was previously aware of the OPA Gatekeeper. From the several demos I saw, it was to me that kyverno should help us make Toolforge Kubernetes more sustainable by replacing all of our custom admission controllers with it. I already opened a ticket to track this idea, which I ll be proposing to my team soon. Final notes In general, I believe I learned many things, and perhaps even more importantly I re-learned some stuff I had forgotten because of lack of daily exposure. I m really happy that the cloud native way of thinking was reinforced in me, which I still need because most of my muscle memory to approach systems architecture and engineering is from the old pre-cloud days. List of sessions I attended on the first day: List of sessions I attended on the second day: List of sessions I attended on third day: The videos have been published on Youtube.

Matt Brown: co2mon.nz: Ventilation monitoring as a service

Previously, I explained why ventilation monitoring is important, and the opportunity I see to help accelerate deployment of high quality ventilation monitoring for small businesses and organisations. In this post, I m going to discuss my plans to tackle that opportunity:

My journey to ventilation monitoring I started looking into ventilation monitoring in detail last year when I wanted to ensure that the classrooms of our local primary school were well ventilated during the Omicron outbreak. That research revealed that the existing products on offer were challenging to deploy in a school environment from a cost perspective while also not providing perfect functionality. I built and deployed a set of monitors to our local school, along with a corresponding set of software and web services that provide management of the monitors and visibility into the collected data and trends. The benefit of the monitoring is evident - CO2 concentration drops immediately after a notification occurs, indicating the intended action of increasing ventilation is taking place. Initially this occurred more frequently, but over time low concentrations of CO2, indicating good ventilation levels, are regularly achieved across the school day thanks to simple changes in routine being established, such as leaving windows cracked open. As the benefits of the project to the school became clear, my ambition and vision for ventilation monitoring grew from wanting to see my children learn in a safe and effective environment to desiring safe and effective learning, working, living and social spaces for everyone.

co2mon.nz: Ventilation monitoring as a service prototype co2mon.nz is the service that I have launched to explore this opportunity. Based on the same hardware and software that I used for the school deployment I am selling both a physical CO2 monitor and an ongoing subscription service for the management and monitoring. Together, the monitor and software provide an effective and affordable path to understanding indoor air quality and ventilation status that anyone can use.

CO2 monitor The CO2 monitor hardware and firmware are based on Oliver Seiler s design using a Sensirion SCD40 module for CO2 measurement and providing immediate in-room feedback via an on-monitor screen as well as a red/orange/green traffic light . In addition to the immediate feedback provided by the monitor itself, a WiFi connection can be configured allowing every measurement to be reported back to the supporting monitoring and management service. At the current prototype stage, I am building all the hardware, 3D printing the plastic cases and assembling the circuit board from purchased components through a production line in my home workshop. The monitor is powered via a standard USB cable and wall adaptor for simplicity. The first batch of monitors I built have been operating smoothly for nearly a year now. Further refinement and development of the design is required but already I am impressed with the potential this combination of easily accessible components provides to enable widespread adoption and deployment of ventilation monitoring.

Monitoring and management service The web service provides a historical record of CO2 levels from each monitor through a set of graphs and other dashboards and allows for this data to be shared or published. This is useful both for providing visibility into ventilation status to those not directly present in the space (e.g. across an entire school) and to allow insights into trends and patterns in ventilation to be observed and acted upon. When I began the project I approached the software side as an opportunity to explore the real-world equivalents of many of the internal tools and components that I was used to using within Google. That s been a fun process, even though it means I ve invested far more time on the software than the current number of customers or business state can really justify. Communication with the monitors occurs via MQTT into a custom Go service responsible for maintaining the fleet and exposing the measurement data to Prometheus which acts as the storage layer. A second service (based on the Buffalo web framework) is responsible for serving the web interface containing the dashboards and configuration options. Alongside these core components another small Golang service manages a private X509 certificate authority to provide monitor identity and encryption of the measurement data and an automated pipeline of scripts and triggers takes care of firmware provisioning, sensor calibration and burn-in/failure testing when building batches of monitors. While simple, the design is easy to manage and could scale to support many, many more monitors without significant effort. I m hosting the infrastructure on AWS, which I ve found pleasant and easy to use, and while not a typical choice, I m very pleased with the performance and flexibility that Prometheus offers as a data storage layer.

Areas of development The prototype has been effective in proving the feasibility of offering ventilation monitoring as a service, but to evolve the prototype into an actual business is going to require further effort in the following areas:

Finding product market fit I m confident that what co2mon.nz is offering could provide a useful and needed service for many small business owners and numerous others, but the question of whether it s sufficiently compelling that a sizeable group of customers see enough value that they re willing to regularly pay for it and therefore sustain a business providing the service is not yet proven. While initial feedback on the idea has been positive, much of it has been from family and friends and I ve spent more time building the software (which has been fun and educational) than I have talking to actual potential customers and understanding their needs and wants. This is a classic trap that technical founders fall into, and I m guilty despite my best intentions it s comfortable and easy for me to work on the parts where I have existing experience and neglect putting time into the customer-facing sales, marketing and research which are more uncomfortable, new and challenging!

Scaling monitor production Scaling from the current prototype batches I have built to even modest levels (e.g. hundreds) of sales will require outsourcing. There are several potential New Zealand and overseas providers I can work with which look very promising, but will require iteration of the hardware design (e.g. to remove through-hole components which add complexity and expense to the PCB assembly process). The lead times I ve been quoted for working with these outsourced providers are in the order of 1-2 months per batch, and on top of this there are a number of other risks in terms of component availability and regulatory compliance that may add additional delays or time to resolve, particularly as my experience leans towards the software rather than the hardware. It seems counter-intuitive to worry about how to scale to meet demand that doesn t yet provably exist, but given the potentially long lead times involved in establishing outsourced production I think it s worth taking some risk in starting this journey early.

Next steps My aim now is to intentionally change my focus from the software to learning about the market and finding the right product to offer via two channels:
  1. Via online marketing, to reach a wide range of potential customers and allow rapid iteration and testing of a variety of product/service combinations, including referral options for existing customers.
  2. In-person with small businesses in my local area to seek out direct feedback and thoughts on the general issue of ventilation monitoring and the specific service I m offering.
One concrete possibility I m keen to test via both channels is a simple monthly price for the combined service, rather than purchasing a monitor and separate software subscription. This has the potential to be both simpler to market and explain to customers, while also opening the possibility of short-term rental or evaluation to customers who are not willing to make a long-term investment or commitment. In parallel to the customer-focused discovery work, but as an explicit lower priority, I ll order an initial small batch of outsourced monitors to begin gaining experience with that process accepting the risk that the time and cost may turn out to be wasted if the product is wrong or not a good match for customers needs.

Russ Allbery: Review: The Last Hero

Review: The Last Hero, by Terry Pratchett
Illustrator: Paul Kidby
Series: Discworld #27
Publisher: Harper
Copyright: 2001, 2002
ISBN: 0-06-050777-2
Format: Graphic novel
Pages: 176
The Last Hero is the 27th Discworld novel and part of the Rincewind subseries. This is something of a sequel to Interesting Times and relies heavily on the cast that was built up in previous books. It's not a good place to start with the series. At last, the rare Rincewind novel that I enjoyed. It helps that Rincewind is mostly along for the ride. Cohen the Barbarian and his band of elderly heroes have decided they're tired of enjoying their spoils and are going on a final adventure. They're going to return fire to the gods, in the form of a giant bomb. The wizards in Ankh-Morpork get wind of this and realize that an explosion at the Hub where the gods live could disrupt the magical field of the entire Disc, effectively destroying it. The only hope seems to be to reach Cori Celesti before Cohen and head him off, but Cohen is already almost there. Enter Lord Vetinari, who has Leonard of Quirm design a machine that will get them there in time by slingshotting under the Disc itself. First off, let me say how much I love the idea of returning fire to the gods with interest. I kind of wish Pratchett had done more with their motivations, but I was laughing about that through the whole book. Second, this is the first of the illustrated Discworld books that I've read in the intended illustrated form (I read the paperback version of Eric), and this book is gorgeous. I enjoyed Paul Kidby's art far more than I had expected to. His style what I will call, for lack of better terminology due to my woeful art education, "highly detailed caricature." That's not normally a style that clicks with me, but it works incredibly well for Discworld. The Last Hero is richly illustrated, with some amount of art, if only subtle background behind the text, on nearly every page. There are several two-page spreads, but oddly I thought those (including the parody of The Scream on the cover) were the worst art of the book. None of them did much for me. The best art is in the figure studies and subtle details: Leonard of Quirm's beautiful calligraphy, his numerous sketches, the labeled illustration of the controls of the flying machine, and the portraits of Cohen's band and the people they encounter. The edition I got is printed on lovely, thick glossy paper, and the subtle art texture behind the writing makes this book a delight to read. I'm not sure if, like Eric, this book comes in other editions, but if so, I highly recommend getting or finding the high-quality illustrated edition for the best reading experience. The plot, like a lot of the Rincewind books, doesn't amount to much, but I enjoyed the mission to intercept Cohen. Leonard of Quirm is a great character, and the slow revelation of his flying machine design (which I will not spoil) is a delightful combination of Leonardo da Vinci parody, Discworld craziness, and NASA homage. Also, the Librarian is involved, which always improves a Discworld book. (The Luggage, sadly, is not; I would have liked to have seen a richly-illustrated story about it, but it looks like I'll have to find the illustrated version of Eric for that.) There is one of Pratchett's philosophical subtexts here, about heroes and stories and what it means for your story to live on. To be honest, it didn't grab me; it's mostly subtext, and this particular set of characters weren't quite introspective enough to make the philosophy central to the story. Also, I was perhaps too sympathetic to Cohen's goals, and thus not very interested in anyone successfully stopping him. But I had a lot more fun with this one than I usually do with Rincewind books, helped considerably by the illustrations. If you've been skipping Rincewind books in your Discworld read-through and have access to the illustrated edition of The Last Hero, consider making an exception for this one.

Matt Brown: Ventilation Monitoring: Ensuring every space has clean, fresh air

The importance of clean, fresh indoor air is one of the most tangible takeaways of the Covid-19 pandemic. In addition to being an effective risk mitigation strategy for reducing the spread of respiratory illnesses, clean, fresh air is necessary to enable effective cognitive performance. Monitoring indoor air quality is relatively easy to do, but traditionally has not been a key focus. I believe air quality monitoring should be accessible for any indoor space, and for highly occupied indoor spaces should be provided on a continuous basis. This post explores the need and an opportunity for a business that can accelerate the adoption of ventilation monitoring through the following topics:

The importance of indoor air quality Clean, fresh air is fundamental to life and health. That might sound obvious, but unfortunately being obvious is not enough to ensure the air we breathe is in fact always clean and healthy. Repeated studies have revealed that in many cases the air you re breathing at school, in the bus or at work and probably also at home falls well below the ideal of what clean, fresh air should be. Unclean air has potential long-term health impacts and has also been shown to lower cognitive performance impacting the ability to learn and work as well as increasing the risk of transmission of respiratory illnesses like Covid-19 and the flu. Ventilation (replacing old stale air with clean fresh air) is the most effective and economical method of improving and maintaining high indoor air quality. Most New Zealand buildings (including schools and houses) are designed to rely on manual ventilation (opening windows), while newer buildings, often including larger or commercial buildings may use mechanical ventilation involving fans and ducts. Mechanical ventilation including filtration may also be required in situations where the outdoor air is not clean and fresh such as in a city or next to a busy intersection.

Observing the invisible Overall air quality is a complex topic involving many contributing factors, many of which are invisible and not perceptible to us until well after adverse effects or irritation occur. This complexity and lack of visible signal is a large contributing factor to the ignorance and lack of attention towards indoor air quality that is prevalent in most buildings and indoor spaces today. Our attention is biased towards the risks that we can see, and this default bias has not been helped by hesitation and resistance to the idea that aerosol transmission and air quality is an important factor in preventing disease transmission that has only recently started to change. Zeynep Tufekci has a great overview that provides fascinating context for how an overreaction to the early incorrect theories of bad air and miasma causing disease contributed to aerosol transmission and air quality being incorrectly neglected for so long. Correcting this history of inattention to indoor air quality is going to take time and effort, but one significant step that we can take to help start the journey to ensuring all indoor spaces have clean, healthy air is to make the invisible part visible. The concentration of carbon dioxide (CO2) in a space is an incredibly effective and easy to measure proxy for the ventilation of a space. The atmospheric background level of CO2 is around 420 parts per million (ppm), while our exhaled breath has concentrations as high as 40,000 ppm. Without effective ventilation, one or more people breathing in an enclosed space will rapidly lead to an observable increase in CO2 concentration, which in turn provides a signal that the ventilation is insufficient and needs to be improved. Monitoring CO2 and improving ventilation is not a panacea for all possible air quality issues, but for the majority of buildings and indoor spaces, using CO2 as a proxy for ventilation and increasing ventilation when CO2 levels rise above recommended levels is a simple, effective and achievable approach that will deliver improvements in cognitive performance and reduction in the risk of disease transmission with few, if any, downsides or risks. See this Public Health Communication Centre briefing for a more detailed explanation.

Adding clean air to our hygiene practices We have well established expectations of hygiene for the food we eat and the water we drink and these expectations are codified in regulations that ensure those providing these services do so in a way that gives us confidence that we re not going to be at risk of illness. You may recall seeing food grade ratings prominently displayed on the walls of restaurants and cafes that you visit as an example of this. Why should the air we breathe be treated any differently? I think there is a strong argument that indoor air quality deserves regulation, both of the absolute quality of the air and ensuring that the practices and achieved air quality are clearly advertised and available. Ventilation monitoring via measurement of CO2 concentration provides an effective and achievable method that can be used to achieve this, and countries like Belgium and Japan are already starting to regulate indoor air quality. In the UK, the independent SAGE group of scientists has published Scores on the Doors , a proposal which demonstrates how CO2 monitoring can be helpful in providing information about the air quality of indoor spaces. Unfortunately there is no movement in any of these directions in New Zealand yet, and no sign that regulation or even a basic campaign to raise awareness of ventilation and air quality is even being planned. This is disappointing, but even if such work was planned, it would still require appropriate ventilation monitoring products and services to enable it, and while there are some options available, it is not a fully solved space yet.

Existing ventilation monitoring options Until recently the available offerings for ventilation monitoring have sat at two distinct ends of the price and quality spectrum:
  • Handheld air quality meters advertised as measuring CO2, but in reality reporting only an approximation. These meters do not contain actual CO2 sensors, and only approximate CO2 levels based on measurements of other components of the air. While cheap (often less than $100), these meters are not useful for providing reliable data that can be systematically used to assess and improve ventilation and should be avoided.
  • High-end building management systems (BMS), and industrial measurement products targeted at large buildings such as offices or commercial applications such as food production. These systems require specialist installation, often integrated with large whole-building air conditioning systems. These systems, if appropriately configured, can be a great solution for the types of buildings and spaces that can afford them, but by their nature and cost, they do not offer a solution for the majority of smaller buildings and indoor spaces where we tend to spend a lot of our time.
Over the last few years a growing number of companies have developed products that fit in between the unreliable air quality meters and the expensive BMS/industrial measurement products. Promising NZ-based options in this space include Air Suite, Tether and Monkeytronics. These products are wall mountable, resemble a smoke alarm and utilise a WiFi network to report their measurements to a supporting web service. Pricing varies between $200 and $300 ex GST per unit. Aranet, while not NZ based, provides a handheld monitor the Aranet4 Home, which is well regarded for quality and accuracy. Aranet4 Home devices are the most expensive in this space, retailing at $386 ex GST and offer a clunkier and less convenient set of connectivity options via a Bluetooth connection to an associated phone. To obtain similar reporting functionality to the other products requires upgrading to their Pro model and purchasing a separate base station at a combined cost of $1255 ex GST. Outside the commercial product offerings are a number of open source DIY options, which can be built by anyone with basic electronics knowledge. AirGradient is a leading example based in Thailand, and within New Zealand Oliver Seiler s CO2 Monitor provides similar functionality. These open source options have a parts cost in the $100-$150 range, depending on volume built and provide high-quality measurements via trusted CO2 sensors while also offering huge flexibility in terms of how they operate, interact with users and potential supporting web services.

An opportunity: Small businesses and organisations While a growing number of high-quality CO2 monitors has the potential to help drive increased adoption of ventilation monitoring, the plethora of small businesses and organisations that own, operate and manage many of the indoor spaces we visit on a day-to-day basis do not appear to be well served by these existing products. To deploy ventilation monitoring a small business or organisation needs to first become aware of the need or demand for it, and then have a simple and easy path to acquire and install the monitor and access the data. Little to no marketing or demand generation appears to be targeted towards this market from the existing businesses and tellingly, several of the products are not directly available for sale, requiring interaction with a salesperson to purchase. This indicates a focus on selling to larger customers who have a campus or portfolio of buildings and will purchase in larger quantities than the typical small business or organisation will. Small businesses and organisations are likely to occupy smaller buildings and spaces where manual ventilation is the prevalent method of improving and maintaining air quality. Maintaining clean, fresh air via manual ventilation requires the occupants of the space to receive an obvious and straightforward signal when action (opening windows, etc) is required. While the products above all tend to provide some form of local feedback and display in the room, the indication provided and notification of when to take action is less obvious and prominent than would be ideal in a situation where manual ventilation is being relied upon. Informally testing this opportunity with family and friends running small businesses over the last few months has resulted in promising feedback. One particular success story was the discovery of a fresh air duct on the air conditioning unit in a small office that had never been connected to the outside air and was simply recirculating air from the ceiling space back into an office! The resulting stuffiness and poor air quality had been noticed, but without the clear indication from the CO2 monitor that the air conditioning was actually making things worse, rather than better, the underlying issue had not been understood. With the issue fixed and the duct now connected, that business is now enjoying much more productive and healthy working conditions.

Next steps Many small businesses and organisations are likely to have poor air quality and opportunities for improvement similar to the example above that are waiting to be found and fixed, and the existing products available are neither focused or ideal for the needs of this market. I have spent some time over the past six months building a basic CO2 monitoring service that I have used to deploy ventilation monitoring to our local school, and a few other local businesses. There are a number of challenges that still need to be addressed in order to scale the business up, but I think there is a reasonable chance that I can build a viable business that offers an attractive and useful solution that would accelerate the deployment of ventilation monitoring for small businesses and organisations. In an upcoming post, I will explain the foundations of the service that I have built to date, the challenges that need to be overcome and how I plan to evolve the service from the current prototype into a sustainable, bootstrapped business.

Russ Allbery: Review: The Star Fraction

Review: The Star Fraction, by Ken MacLeod
Series: Fall Revolution #1
Publisher: Orbit
Copyright: 1995
Printing: 2001
ISBN: 1-85723-833-8
Format: Trade paperback
Pages: 341
Ken MacLeod is a Scottish science fiction writer who has become amusingly famous for repeatedly winning the libertarian Prometheus Award despite being a (somewhat libertarian-leaning) socialist. The Star Fraction is the first of a loose series of four novels about future solar system politics and was nominated for the Clarke Award (as well as winning the Prometheus). It was MacLeod's first novel. Moh Kohn is a mercenary, part of the Felix Dzerzhinsky Workers' Defence collective. They're available for hire to protect research labs and universities against raids from people such as animal liberationists and anti-AI extremists (or, as Moh calls them, creeps and cranks). As The Star Fraction opens, he and his smart gun are protecting a lab against an attack. Janis Taine is a biologist who is currently testing a memory-enhancing drug on mice. It's her lab that is attacked, although it isn't vandalized the way she expected. Instead, the attackers ruined her experiment by releasing the test drug into the air, contaminating all of the controls. This sets off a sequence of events that results in Moh, Janis, and Jordon Brown, a stock trader for a religious theocracy, on the run from the US/UN and Space Defense. I had forgotten what it was like to read the uncompromising old-school style of science fiction novel that throws you into the world and explains nothing, leaving it to the reader to piece the world together as you go. It's weirdly fun, but I'm either out of practice or this was a particularly challenging example of the genre. MacLeod throws a lot of characters at you quickly, including some that have long and complicated personal histories, and it's not until well into the book that the pieces start to cohere into a narrative. Even once that happens, the relationship between the characters and the plot is unobvious until late in the book, and comes from a surprising direction. Science fiction as a genre is weirdly conservative about political systems. Despite the grand, futuristic ideas and the speculation about strange alien societies, the human governments rarely rise to the sophistication of a modern democracy. There are a lot of empires, oligarchies, and hand-waved libertarian semi-utopias, but not a lot of deep engagement with the speculative variety of government systems humans have proposed. The rare exceptions therefore get a lot of attention from those of us who find political systems fascinating. MacLeod has a reputation for writing political SF in that sense, and The Star Fraction certainly delivers. Moh (despite the name of his collective, which is explained briefly in the book) is a Trotskyist with a family history with the Fourth International that is central to the plot. The setting is a politically fractured Britain full of autonomous zones with wildly different forms of government, theoretically ruled by a restored monarchy. That monarchy is opposed by the Army of the New Republic, which claims to be the legitimate government of the United Kingdom and is considered by everyone else to be terrorists. Hovering in the background is a UN entirely subsumed by the US, playing global policeman over a chaotic world shattered by numerous small-scale wars. This satisfyingly different political world is a major plus for me. The main drawback is that I found the world-building and politics more interesting than the characters. It's not that I disliked them; I found them enjoyably quirky and odd. It's more that so much is happening and there are so many significant characters, all set in an unfamiliar and unexplained world and often divided into short scenes of a few pages, that I had a hard time keeping track of them all. Part of the point of The Star Fraction is digging into their tangled past and connecting it up with the present, but the flashbacks added a confused timeline on top of the other complexity and made it hard for me to get lost in the story. The characters felt a bit too much like puzzle pieces until the very end of the book. The technology is an odd mix with a very 1990s feel. MacLeod is one of the SF authors who can make computers and viruses believable, avoiding the cyberpunk traps, but AI becomes relevant to the plot and the conception of AI here feels oddly retro. (Not MacLeod's fault; it's been nearly 30 years and a lot has changed.) On-line discussion in the book is still based on newsgroups, which added to the nostalgic feel. I did like the eventual explanation for the computing part of the plot, though; I can't say much while avoiding spoilers, but it's one of the more believable explanations for how a technology could spread in a way required for the plot that I've read. I've been planning on reading this series for years but never got around to it. I enjoyed my last try at a MacLeod series well enough to want to keep reading, but not well enough to keep reading immediately, and then other books happened and now it's been 19 years. I feel similarly about The Star Fraction: it's good enough (and in a rare enough subgenre of SF) that I want to keep reading, but not enough to keep reading immediately. We'll see if I manage to get to the next book in a reasonable length of time. Followed by The Stone Canal. Rating: 6 out of 10

Chris Lamb: Most anticipated films of 2023

Very few highly-anticipated movies appear in January and February, as the bigger releases are timed so they can be considered for the Golden Globes in January and the Oscars in late February or early March, so film fans have the advantage of a few weeks after the New Year to collect their thoughts on the year ahead. In other words, I'm not actually late in outlining below the films I'm most looking forward to in 2023...

Barbie No, seriously! If anyone can make a good film about a doll franchise, it's probably Greta Gerwig. Not only was Little Women (2019) more than admirable, the same could be definitely said for Lady Bird (2017). More importantly, I can't help feel she was the real 'Driver' behind Frances Ha (2012), one of the better modern takes on Claudia Weill's revelatory Girlfriends (1978). Still, whenever I remember that Barbie will be a film about a billion-dollar toy and media franchise with a nettlesome history, I recall I rubbished the "Facebook film" that turned into The Social Network (2010). Anyway, the trailer for Barbie is worth watching, if only because it seems like a parody of itself.

Blitz It's difficult to overstate just how important the aerial bombing of London during World War II is crucial to understanding the British psyche, despite it being a constructed phenomenon from the outset. Without wishing to underplay the deaths of over 40,000 civilian deaths, Angus Calder pointed out in the 1990s that the modern mythology surrounding the event "did not evolve spontaneously; it was a propaganda construct directed as much at [then neutral] American opinion as at British." It will therefore be interesting to see how British Grenadian Trinidadian director Steve McQueen addresses a topic so essential to the British self-conception. (Remember the controversy in right-wing circles about the sole Indian soldier in Christopher Nolan's Dunkirk (2017)?) McQueen is perhaps best known for his 12 Years a Slave (2013), but he recently directed a six-part film anthology for the BBC which addressed the realities of post-Empire immigration to Britain, and this leads me to suspect he sees the Blitz and its surrounding mythology with a more critical perspective. But any attempt to complicate the story of World War II will be vigorously opposed in a way that will make the recent hullabaloo surrounding The Crown seem tame. All this is to say that the discourse surrounding this release may be as interesting as the film itself.

Dune, Part II Coming out of the cinema after the first part of Denis Vileneve's adaptation of Dune (2021), I was struck by the conception that it was less of a fresh adaptation of the 1965 novel by Frank Herbert than an attempt to rehabilitate David Lynch's 1984 version and in a broader sense, it was also an attempt to reestablish the primacy of cinema over streaming TV and the myriad of other distractions in our lives. I must admit I'm not a huge fan of the original novel, finding within it a certain prurience regarding hereditary military regimes and writing about them with a certain sense of glee that belies a secret admiration for them... not to mention an eyebrow-raising allegory for the Middle East. Still, Dune, Part II is going to be a fantastic spectacle.

Ferrari It'll be curious to see how this differs substantially from the recent Ford v Ferrari (2019), but given that Michael Mann's Heat (1995) so effectively re-energised the gangster/heist genre, I'm more than willing to kick the tires of this about the founder of the eponymous car manufacturer. I'm in the minority for preferring Mann's Thief (1981) over Heat, in part because the former deals in more abstract themes, so I'd have perhaps prefered to look forward to a more conceptual film from Mann over a story about one specific guy.

How Do You Live There are a few directors one can look forward to watching almost without qualification, and Hayao Miyazaki (My Neighbor Totoro, Kiki's Delivery Service, Princess Mononoke Howl's Moving Castle, etc.) is one of them. And this is especially so given that The Wind Rises (2013) was meant to be the last collaboration between Miyazaki and Studio Ghibli. Let's hope he is able to come out of retirement in another ten years.

Indiana Jones and the Dial of Destiny Given I had a strong dislike of Indiana Jones and the Kingdom of the Crystal Skull (2008), I seriously doubt I will enjoy anything this film has to show me, but with 1981's Raiders of the Lost Ark remaining one of my most treasured films (read my brief homage), I still feel a strong sense of obligation towards the Indiana Jones name, despite it feeling like the copper is being pulled out of the walls of this franchise today.

Kafka I only know Polish filmmaker Agnieszka Holland through her Spoor (2017), an adaptation of Olga Tokarczuk's 2009 eco-crime novel Drive Your Plow Over the Bones of the Dead. I wasn't an unqualified fan of Spoor (nor the book on which it is based), but I am interested in Holland's take on the life of Czech author Franz Kafka, an author enmeshed with twentieth-century art and philosophy, especially that of central Europe. Holland has mentioned she intends to tell the story "as a kind of collage," and I can hope that it is an adventurous take on the over-furrowed biopic genre. Or perhaps Gregor Samsa will awake from uneasy dreams to find himself transformed in his bed into a huge verminous biopic.

The Killer It'll be interesting to see what path David Fincher is taking today, especially after his puzzling and strangely cold Mank (2020) portraying the writing process behind Orson Welles' Citizen Kane (1941). The Killer is said to be a straight-to-Netflix thriller based on the graphic novel about a hired assassin, which makes me think of Fincher's Zodiac (2007), and, of course, Se7en (1995). I'm not as entranced by Fincher as I used to be, but any film with Michael Fassbender and Tilda Swinton (with a score by Trent Reznor) is always going to get my attention.

Killers of the Flower Moon In Killers of the Flower Moon, Martin Scorsese directs an adaptation of a book about the FBI's investigation into a conspiracy to murder Osage tribe members in the early years of the twentieth century in order to deprive them of their oil-rich land. (The only thing more quintessentially American than apple pie is a conspiracy combined with a genocide.) Separate from learning more about this disquieting chapter of American history, I'd love to discover what attracted Scorsese to this particular story: he's one of the few top-level directors who have the ability to lucidly articulate their intentions and motivations.

Napoleon It often strikes me that, despite all of his achievements and fame, it's somehow still possible to claim that Ridley Scott is relatively underrated compared to other directors working at the top level today. Besides that, though, I'm especially interested in this film, not least of all because I just read Tolstoy's War and Peace (read my recent review) and am working my way through the mind-boggling 431-minute Soviet TV adaptation, but also because several auteur filmmakers (including Stanley Kubrick) have tried to make a Napoleon epic and failed.

Oppenheimer In a way, a biopic about the scientist responsible for the atomic bomb and the Manhattan Project seems almost perfect material for Christopher Nolan. He can certainly rely on stars to queue up to be in his movies (Robert Downey Jr., Matt Damon, Kenneth Branagh, etc.), but whilst I'm certain it will be entertaining on many fronts, I fear it will fall into the well-established Nolan mould of yet another single man struggling with obsession, deception and guilt who is trying in vain to balance order and chaos in the world.

The Way of the Wind Marked by philosophical and spiritual overtones, all of Terrence Malick's films are perfumed with themes of transcendence, nature and the inevitable conflict between instinct and reason. My particular favourite is his stunning Days of Heaven (1978), but The Thin Red Line (1998) and A Hidden Life (2019) also touched me ways difficult to relate, and are one of the few films about the Second World War that don't touch off my sensitivity about them (see my remarks about Blitz above). It is therefore somewhat Malickian that his next film will be a biblical drama about the life of Jesus. Given Malick's filmography, I suspect this will be far more subdued than William Wyler's 1959 Ben-Hur and significantly more equivocal in its conviction compared to Paolo Pasolini's ardently progressive The Gospel According to St. Matthew (1964). However, little beyond that can be guessed, and the film may not even appear until 2024 or even 2025.

Zone of Interest I was mesmerised by Jonathan Glazer's Under the Skin (2013), and there is much to admire in his borderline 'revisionist gangster' film Sexy Beast (2000), so I will definitely be on the lookout for this one. The only thing making me hesitate is that Zone of Interest is based on a book by Martin Amis about a romance set inside the Auschwitz concentration camp. I haven't read the book, but Amis has something of a history in his grappling with the history of the twentieth century, and he seems to do it in a way that never sits right with me. But if Paul Verhoeven's Starship Troopers (1997) proves anything at all, it's all in the adaption.

B lint R czey: How to speed up your next build 5-20x with Firebuild?

Firebuild logo
TL;DR: Just prefix your build command (or any command) with firebuild:
firebuild <build command>
OK, but how does it work? Firebuild intercepts all processes started by the command to cache their outputs. Next time when the command or any of its descendant commands is executed with the same parameters, inputs and environment, the outputs are replayed (the command is shortcut) from the cache instead of running the command again. This is similar to how ccache and other compiler-specific caches work, but firebuild can shortcut any deterministic command, not only a specific list of compilers. Since the inputs of each command is determined at run time firebuild does not need a maintained complete dependency graph in the source like Bazel. It can work with any build system that does not implement its own caching mechanism. Determinism of commands is detected at run-time by preloading libfirebuild.so and interposing standard library calls and syscalls. If the command and all its descendants inputs are available when the command starts and all outputs can be calculated from the inputs then the command can be shortcut, otherwise it will be executed again. The interception comes with a 5-10% overhead, but rebuilds can be 5-20 times, or even faster depending on the changes between the builds. Can I try it? It is already available in Debian Unstable and Testing, Ubuntu s development release and the latest stable version is back-ported to supported Ubuntu releases via a PPA. How can I analyze my builds with firebuild? Firebuild can generate an HTML report showing each command s contribution to the build time. Below are the before and after reports of json4s, a Scala project. The command call graphs (lower ones) show that java (scalac) took 99% of the original build. Since the scalac invocations are shortcut (cutting the second build s time to less than 2% of the first one) they don t even show up in the accelerated second build s call graph. What s left to be executed again in the second run are env, perl, make and a few simple commands. The upper graphs are the process trees, with expandable nodes (in blue) also showing which command invocations were shortcut (green). Clicking on a node shows details of the command and the reason if it was not shortcut. Could I accelerate my project more? Firebuild works best for builds with CPU-intensive processes and comes with defaults to not cache very quick commands, such as sh, grep, sed, etc., because caching those would take cache space and shortcutting them may not speed up the build that much. They can still be shortcut with their parent command. Firebuild s strength is that it can find shortcutting points in the process tree automatically, e.g. from sh -c 'bash -c "sh -c echo Hello World!"' bash would be shortcut, but none of the sh commands would be cached. In typical builds there are many such commands from the skip_cache list. Caching those commands with firebuild -o 'processes.skip_cache = []' can improve acceleration and make the reports smaller. Firebuild also supports several debug flags and -d proc helps finding reasons for not shortcutting some commands:
...
FIREBUILD: Command "/usr/bin/make" can't be short-cut due to: Executable set to be not shortcut,  ExecedProcess 1329.2, running, "make -f debian/rules build", fds=[ FileFD fd=0  FileOFD ...
FIREBUILD: Command "/usr/bin/sort" can't be short-cut due to: Process read from inherited fd ,  ExecedProcess 4161.1, running, "sort", fds=[ FileFD fd=0  FileOFD ...
FIREBUILD: Command "/usr/bin/find" can't be short-cut due to: fstatfs() family operating on fds is not supported,  ExecedProcess 1360.1, running, "find -mindepth 1 ...
...
make, ninja and other incremental build tool binaries are not shortcut because they compare the timestamp of files, but they are fast at least and every build step they perform can still be shortcut. Ideally the slower build steps that could not be shortcut can be re-implemented in ways that can be shortcut by avoiding tools performing unsupported operations. I hope those tools help speeding up your build with very little effort, but if not and you find something to fix or improve in firebuild itself, please report it or just leave a feedback! Happy speeding, but not on public roads!

Chris Lamb: Favourite books of 2022: Non-fiction

In my three most recent posts, I went over the memoirs and biographies, classics and fiction books that I enjoyed the most in 2022. But in the last of my book-related posts for 2022, I'll be going over my favourite works of non-fiction. Books that just missed the cut here include Adam Hochschild's King Leopold's Ghost (1998) on the role of Leopold II of Belgium in the Congo Free State, Johann Hari's Stolen Focus (2022) (a personal memoir on relating to how technology is increasingly fragmenting our attention), Amia Srinivasan's The Right to Sex (2021) (a misleadingly named set of philosophic essays on feminism), Dana Heller et al.'s The Selling of 9/11: How a National Tragedy Became a Commodity (2005), John Berger's mindbending Ways of Seeing (1972) and Louise Richardson's What Terrorists Want (2006).

The Great War and Modern Memory (1975)
Wartime: Understanding and Behavior in the Second World War (1989) Paul Fussell Rather than describe the battles, weapons, geopolitics or big personalities of the two World Wars, Paul Fussell's The Great War and Modern Memory & Wartime are focused instead on how the two wars have been remembered by their everyday participants. Drawing on the memoirs and memories of soldiers and civilians along with a brief comparison with the actual events that shaped them, Fussell's two books are a compassionate, insightful and moving piece of analysis. Fussell primarily sets himself against the admixture of nostalgia and trauma that obscures the origins and unimaginable experience of participating in these wars; two wars that were, in his view, a "perceptual and rhetorical scandal from which total recovery is unlikely." He takes particular aim at the dishonesty of hindsight:
For the past fifty years, the Allied war has been sanitised and romanticised almost beyond recognition by the sentimental, the loony patriotic, the ignorant and the bloodthirsty. I have tried to balance the scales. [And] in unbombed America especially, the meaning of the war [seems] inaccessible.
The author does not engage in any of the customary rose-tinted view of war, yet he remains understanding and compassionate towards those who try to locate a reason within what was quite often senseless barbarism. If anything, his despondency and pessimism about the Second World War (the war that Fussell himself fought in) shines through quite acutely, and this is especially the case in what he chooses to quote from others:
"It was common [ ] throughout the [Okinawa] campaign for replacements to get hit before we even knew their names. They came up confused, frightened, and hopeful, got wounded or killed, and went right back to the rear on the route by which they had come, shocked, bleeding, or stiff. They were forlorn figures coming up to the meat grinder and going right back out of it like homeless waifs, unknown and faceless to us, like unread books on a shelf."
It would take a rather heartless reader to fail to be sobered by this final simile, and an even colder one to view Fussell's citation of such an emotive anecdote to be manipulative. Still, stories and cruel ironies like this one infuse this often-angry book, but it is not without astute and shrewd analysis as well, especially on the many qualitative differences between the two conflicts that simply cannot be captured by facts and figures alone. For example:
A measure of the psychological distance of the Second [World] War from the First is the rarity, in 1914 1918, of drinking and drunkenness poems.
Indeed so. In fact, what makes Fussell's project so compelling and perhaps even unique is that he uses these non-quantitive measures to try and take stock of what happened. After all, this was a war conducted by humans, not the abstract school of statistics. And what is the value of a list of armaments destroyed by such-and-such a regiment when compared with truly consequential insights into both how the war affected, say, the psychology of postwar literature ("Prolonged trench warfare, whether enacted or remembered, fosters paranoid melodrama, which I take to be a primary mode in modern writing."), the specific words adopted by combatants ("It is a truism of military propaganda that monosyllabic enemies are easier to despise than others") as well as the very grammar of interaction:
The Field Service Post Card [in WW1] has the honour of being the first widespread exemplary of that kind of document which uniquely characterises the modern world: the "Form". [And] as the first widely known example of dehumanised, automated communication, the post card popularised a mode of rhetoric indispensable to the conduct of later wars fought by great faceless conscripted armies.
And this wouldn't be a book review without argument-ending observations that:
Indicative of the German wartime conception [of victory] would be Hitler and Speer's elaborate plans for the ultimate reconstruction of Berlin, which made no provision for a library.
Our myths about the two world wars possess an undisputed power, in part because they contain an essential truth the atrocities committed by Germany and its allies were not merely extreme or revolting, but their full dimensions (embodied in the Holocaust and the Holodomor) remain essentially inaccessible within our current ideological framework. Yet the two wars are better understood as an abyss in which we were all dragged into the depths of moral depravity, rather than a battle pitched by the forces of light against the forces of darkness. Fussell is one of the few observers that can truly accept and understand this truth and is still able to speak to us cogently on the topic from the vantage point of experience. The Second World War which looms so large in our contemporary understanding of the modern world (see below) may have been necessary and unavoidable, but Fussell convinces his reader that it was morally complicated "beyond the power of any literary or philosophic analysis to suggest," and that the only way to maintain a na ve belief in the myth that these wars were a Manichaean fight between good and evil is to overlook reality. There are many texts on the two World Wars that can either stir the intellect or move the emotions, but Fussell's two books do both. A uniquely perceptive and intelligent commentary; outstanding.

Longitude (1995) Dava Sobel Since Man first decided to sail the oceans, knowing one's location has always been critical. Yet doing so reliably used to be a serious problem if you didn't know where you were, you are far more likely to die and/or lose your valuable cargo. But whilst finding one's latitude (ie. your north south position) had effectively been solved by the beginning of the 17th century, finding one's (east west) longitude was far from trustworthy in comparison. This book first published in 1995 is therefore something of an anachronism. As in, we readily use the GPS facilities of our phones today without hesitation, so we find it difficult to imagine a reality in which knowing something fundamental like your own location is essentially unthinkable. It became clear in the 18th century, though, that in order to accurately determine one's longitude, what you actually needed was an accurate clock. In Longitude, therefore, we read of the remarkable story of John Harrison and his quest to create a timepiece that would not only keep time during a long sea voyage but would survive the rough ocean conditions as well. Self-educated and a carpenter by trade, Harrison made a number of important breakthroughs in keeping accurate time at sea, and Longitude describes his novel breakthroughs in a way that is both engaging and without talking down to the reader. Still, this book covers much more than that, including the development of accurate longitude going hand-in-hand with advancements in cartography as well as in scientific experiments to determine the speed of light: experiments that led to the formulation of quantum mechanics. It also outlines the work being done by Harrison's competitors. 'Competitors' is indeed the correct word here, as Parliament offered a huge prize to whoever could create such a device, and the ramifications of this tremendous financial incentive are an essential part of this story. For the most part, though, Longitude sticks to the story of Harrison and his evolving obsession with his creating the perfect timepiece. Indeed, one reason that Longitude is so resonant with readers is that many of the tropes of the archetypical 'English inventor' are embedded within Harrison himself. That is to say, here is a self-made man pushing against the establishment of the time, with his groundbreaking ideas being underappreciated in his life, or dishonestly purloined by his intellectual inferiors. At the level of allegory, then, I am minded to interpret this portrait of Harrison as a symbolic distillation of postwar Britain a nation acutely embarrassed by the loss of the Empire that is now repositioning itself as a resourceful but plucky underdog; a country that, with a combination of the brains of boffins and a healthy dose of charisma and PR, can still keep up with the big boys. (It is this same search for postimperial meaning I find in the fiction of John le Carr , and, far more famously, in the James Bond franchise.) All of this is left to the reader, of course, as what makes Longitute singularly compelling is its gentle manner and tone. Indeed, at times it was as if the doyenne of sci-fi Ursula K. LeGuin had a sideline in popular non-fiction. I realise it's a mark of critical distinction to downgrade the importance of popular science in favour of erudite academic texts, but Latitude is ample evidence that so-called 'pop' science need not be patronising or reductive at all.

Closed Chambers: The Rise, Fall, and Future of the Modern Supreme Court (1998) Edward Lazarus After the landmark decision by the U.S. Supreme Court in *Dobbs v. Jackson Women's Health Organization that ended the Constitutional right to abortion conferred by Roe v Wade, I prioritised a few books in the queue about the judicial branch of the United States. One of these books was Closed Chambers, which attempts to assay, according to its subtitle, "The Rise, Fall and Future of the Modern Supreme Court". This book is not merely simply a learned guide to the history and functioning of the Court (although it is completely creditable in this respect); it's actually an 'insider' view of the workings of the institution as Lazurus was a clerk for Justice Harry Blackmun during the October term of 1988. Lazarus has therefore combined his experience as a clerk and his personal reflections (along with a substantial body of subsequent research) in order to communicate the collapse in comity between the Justices. Part of this book is therefore a pure history of the Court, detailing its important nineteenth-century judgements (such as Dred Scott which ruled that the Constitution did not consider Blacks to be citizens; and Plessy v. Ferguson which failed to find protection in the Constitution against racial segregation laws), as well as many twentieth-century cases that touch on the rather technical principle of substantive due process. Other layers of Lazurus' book are explicitly opinionated, however, and they capture the author's assessment of the Court's actions in the past and present [1998] day. Given the role in which he served at the Court, particular attention is given by Lazarus to the function of its clerks. These are revealed as being far more than the mere amanuenses they were hitherto believed to be. Indeed, the book is potentially unique in its the claim that the clerks have played a pivotal role in the deliberations, machinations and eventual rulings of the Court. By implication, then, the clerks have plaedy a crucial role in the internal controversies that surround many of the high-profile Supreme Court decisions decisions that, to the outsider at least, are presented as disinterested interpretations of Constitution of the United States. This is of especial importance given that, to Lazarus, "for all the attention we now pay to it, the Court remains shrouded in confusion and misunderstanding." Throughout his book, Lazarus complicates the commonplace view that the Court is divided into two simple right vs. left political factions, and instead documents an ever-evolving series of loosely held but strongly felt series of cabals, quid pro quo exchanges, outright equivocation and pure personal prejudices. (The age and concomitant illnesses of the Justices also appears to have a not insignificant effect on the Court's rulings as well.) In other words, Closed Chambers is not a book that will be read in a typical civics class in America, and the only time the book resorts to the customary breathless rhetoric about the US federal government is in its opening chapter:
The Court itself, a Greek-style temple commanding the crest of Capitol Hill, loomed above them in the dim light of the storm. Set atop a broad marble plaza and thirty-six steps, the Court stands in splendid isolation appropriate to its place at the pinnacle of the national judiciary, one of the three independent and "coequal" branches of American government. Once dubbed the Ivory Tower by architecture critics, the Court has a Corinthian colonnade and massive twenty-foot-high bronze doors that guard the single most powerful judicial institution in the Western world. Lights still shone in several offices to the right of the Court's entrance, and [ ]
Et cetera, et cetera. But, of course, this encomium to the inherent 'nobility' of the Supreme Court is quickly revealed to be a narrative foil, as Lazarus soon razes this dangerously na ve conception to the ground:
[The] institution is [now] broken into unyielding factions that have largely given up on a meaningful exchange of their respective views or, for that matter, a meaningful explication or defense of their own views. It is of Justices who in many important cases resort to transparently deceitful and hypocritical arguments and factual distortions as they discard judicial philosophy and consistent interpretation in favor of bottom-line results. This is a Court so badly splintered, yet so intent on lawmaking, that shifting 5-4 majorities, or even mere pluralities, rewrite whole swaths of constitutional law on the authority of a single, often idiosyncratic vote. It is also a Court where Justices yield great and excessive power to immature, ideologically driven clerks, who in turn use that power to manipulate their bosses and the institution they ostensibly serve.
Lazurus does not put forward a single, overarching thesis, but in the final chapters, he does suggest a potential future for the Court:
In the short run, the cure for what ails the Court lies solely with the Justices. It is their duty, under the shield of life tenure, to recognize the pathologies affecting their work and to restore the vitality of American constitutionalism. Ultimately, though, the long-term health of the Court depends on our own resolve on whom [we] select to join that institution.
Back in 1998, Lazurus might have had room for this qualified optimism. But from the vantage point of 2022, it appears that the "resolve" of the United States citizenry was not muscular enough to meet his challenge. After all, Lazurus was writing before Bush v. Gore in 2000, which arrogated to the judicial branch the ability to decide a presidential election; the disillusionment of Barack Obama's failure to nominate a replacement for Scalia; and many other missteps in the Court as well. All of which have now been compounded by the Trump administration's appointment of three Republican-friendly justices to the Court, including hypocritically appointing Justice Barrett a mere 38 days before the 2020 election. And, of course, the leaking and ruling in Dobbs v. Jackson, the true extent of which has not been yet. Not of a bit of this is Lazarus' fault, of course, but the Court's recent decisions (as well as the liberal hagiographies of 'RBG') most perforce affect one's reading of the concluding chapters. The other slight defect of Closed Chambers is that, whilst it often implies the importance of the federal and state courts within the judiciary, it only briefly positions the Supreme Court's decisions in relation to what was happening in the House, Senate and White House at the time. This seems to be increasingly relevant as time goes on: after all, it seems fairly clear even to this Brit that relying on an activist Supreme Court to enact progressive laws must be interpreted as a failure of the legislative branch to overcome the perennial problems of the filibuster, culture wars and partisan bickering. Nevertheless, Lazarus' book is in equal parts ambitious, opinionated, scholarly and dare I admit it? wonderfully gossipy. By juxtaposing history, memoir, and analysis, Closed Chambers combines an exacting evaluation of the Court's decisions with a lively portrait of the intellectual and emotional intensity that has grown within the Supreme Court's pseudo-monastic environment all while it struggles with the most impactful legal issues of the day. This book is an excellent and well-written achievement that will likely never be repeated, and a must-read for anyone interested in this ever-increasingly important branch of the US government.

Crashed: How a Decade of Financial Crises Changed the World (2018)
Shutdown: How Covid Shook the World's Economy (2021) Adam Tooze The economic historian Adam Tooze has often been labelled as an unlikely celebrity, but in the fourteen years since the global financial crisis of 2008, a growing audience has been looking for answers about the various failures of the modern economy. Tooze, a professor of history at New York's Columbia University, has written much that is penetrative and thought-provoking on this topic, and as a result, he has generated something of a cult following amongst economists, historians and the online left. I actually read two Tooze books this year. The first, Crashed (2018), catalogues the scale of government intervention required to prop up global finance after the 2008 financial crisis, and it characterises the different ways that countries around the world failed to live up to the situation, such as doing far too little, or taking action far too late. The connections between the high-risk subprime loans, credit default swaps and the resulting liquidity crisis in the US in late 2008 is fairly well known today in part thanks to films such as Adam McKay's 2015 The Big Short and much improved economic literacy in media reportage. But Crashed makes the implicit claim that, whilst the specific and structural origins of the 2008 crisis are worth scrutinising in exacting detail, it is the reaction of states in the months and years after the crash that has been overlooked as a result. After all, this is a reaction that has not only shaped a new economic order, it has created one that does not fit any conventional idea about the way the world 'ought' to be run. Tooze connects the original American banking crisis to the (multiple) European debt crises with a larger crisis of liberalism. Indeed, Tooze somehow manages to cover all these topics and more, weaving in Trump, Brexit and Russia's 2014 annexation of Crimea, as well as the evolving role of China in the post-2008 economic order. Where Crashed focused on the constellation of consequences that followed the events of 2008, Shutdown is a clear and comprehensive account of the way the world responded to the economic impact of Covid-19. The figures are often jaw-dropping: soon after the disease spread around the world, 95% of the world's economies contracted simultaneously, and at one point, the global economy shrunk by approximately 20%. Tooze's keen and sobering analysis of what happened is made all the more remarkable by the fact that it came out whilst the pandemic was still unfolding. In fact, this leads quickly to one of the book's few flaws: by being published so quickly, Shutdown prematurely over-praises China's 'zero Covid' policy, and these remarks will make a reader today squirm in their chair. Still, despite the regularity of these references (after all, mentioning China is very useful when one is directly comparing economic figures in early 2021, for examples), these are actually minor blemishes on the book's overall thesis. That is to say, Crashed is not merely a retelling of what happened in such-and-such a country during the pandemic; it offers in effect a prediction about what might be coming next. Whilst the economic responses to Covid averted what could easily have been another Great Depression (and thus showed it had learned some lessons from 2008), it had only done so by truly discarding the economic rule book. The by-product of inverting this set of written and unwritten conventions that have governed the world for the past 50 years, this 'Washington consensus' if you well, has yet to be fully felt. Of course, there are many parallels between these two books by Tooze. Both the liquidity crisis outlined in Crashed and the economic response to Covid in Shutdown exposed the fact that one of the central tenets of the modern economy ie. that financial markets can be trusted to regulate themselves was entirely untrue, and likely was false from the very beginning. And whilst Adam Tooze does not offer a singular piercing insight (conveying a sense of rigorous mastery instead), he may as well be asking whether we're simply going to lurch along from one crisis to the next, relying on the technocrats in power to fix problems when everything blows up again. The answer may very well be yes.

Looking for the Good War: American Amnesia and the Violent Pursuit of Happiness (2021) Elizabeth D. Samet Elizabeth D. Samet's Looking for the Good War answers the following question what would be the result if you asked a professor of English to disentangle the complex mythology we have about WW2 in the context of the recent US exit of Afghanistan? Samet's book acts as a twenty-first-century update of a kind to Paul Fussell's two books (reviewed above), as well as a deeper meditation on the idea that each new war is seen through the lens of the previous one. Indeed, like The Great War and Modern Memory (1975) and Wartime (1989), Samet's book is a perceptive work of demystification, but whilst Fussell seems to have been inspired by his own traumatic war experience, Samet is not only informed by her teaching West Point military cadets but by the physical and ontological wars that have occurred during her own life as well. A more scholarly and dispassionate text is the result of Samet's relative distance from armed combat, but it doesn't mean Looking for the Good War lacks energy or inspiration. Samet shares John Adams' belief that no political project can entirely shed the innate corruptions of power and ambition and so it is crucial to analyse and re-analyse the role of WW2 in contemporary American life. She is surely correct that the Second World War has been universally elevated as a special, 'good' war. Even those with exceptionally giddy minds seem to treat WW2 as hallowed:
It is nevertheless telling that one of the few occasions to which Trump responded with any kind of restraint while he was in office was the 75th anniversary of D-Day in 2019.
What is the source of this restraint, and what has nurtured its growth in the eight decades since WW2 began? Samet posits several reasons for this, including the fact that almost all of the media about the Second World War is not only suffused with symbolism and nostalgia but, less obviously, it has been made by people who have no experience of the events that they depict. Take Stephen Ambrose, author of Steven Spielberg's Band of Brothers miniseries: "I was 10 years old when the war ended," Samet quotes of Ambrose. "I thought the returning veterans were giants who had saved the world from barbarism. I still think so. I remain a hero worshiper." If Looking for the Good War has a primary thesis, then, it is that childhood hero worship is no basis for a system of government, let alone a crusading foreign policy. There is a straight line (to quote this book's subtitle) from the "American Amnesia" that obscures the reality of war to the "Violent Pursuit of Happiness." Samet's book doesn't merely just provide a modern appendix to Fussell's two works, however, as it adds further layers and dimensions he overlooked. For example, Samet provides some excellent insight on the role of Western, gangster and superhero movies, and she is especially good when looking at noir films as a kind of kaleidoscopic response to the Second World War:
Noir is a world ruled by bad decisions but also by bad timing. Chance, which plays such a pivotal role in war, bleeds into this world, too.
Samet rightfully weaves the role of women into the narrative as well. Women in film noir are often celebrated as 'independent' and sassy, correctly reflecting their newly-found independence gained during WW2. But these 'liberated' roles are not exactly a ringing endorsement of this independence: the 'femme fatale' and the 'tart', etc., reflect a kind of conditional freedom permitted to women by a post-War culture which is still wedded to an outmoded honour culture. In effect, far from being novel and subversive, these roles for women actually underwrote the ambient cultural disapproval of women's presence in the workforce. Samet later connects this highly-conditional independence with the liberation of Afghan women, which:
is inarguably one of the more palatable outcomes of our invasion, and the protection of women's rights has been invoked on the right and the left as an argument for staying the course in Afghanistan. How easily consequence is becoming justification. How flattering it will be one day to reimagine it as original objective.
Samet has ensured her book has a predominantly US angle as well, for she ends her book with a chapter on the pseudohistorical Lost Cause of the Civil War. The legacy of the Civil War is still visible in the physical phenomena of Confederate statues, but it also exists in deep-rooted racial injustice that has been shrouded in euphemism and other psychological devices for over 150 years. Samet believes that a key part of what drives the American mythology about the Second World War is the way in which it subconsciously cleanses the horrors of brother-on-brother murder that were seen in the Civil War. This is a book that is not only of interest to historians of the Second World War; it is a work for anyone who wishes to understand almost any American historical event, social issue, politician or movie that has appeared since the end of WW2. That is for better or worse everyone on earth.

Chris Lamb: Favourite books of 2022: Memoir/biography

In my two most recent posts, I listed the fiction and classic fiction I enjoyed the most in 2022. I'll leave my roundup of general non-fiction until tomorrow, but today I'll be going over my favourite memoirs and biographies, in no particular order. Books that just missed the cut here include Roisin Kiberd's The Disconnect: A Personal Journey Through the Internet (2019), Steve Richards' The Prime Ministers (2019) which reflects on UK leadership from Harold Wilson to Boris Johnson, Robert Graves Great War memoir Goodbye to All That (1929) and David Mikics's portrait of Stanley Kubrick called American Filmmaker.

Afropean: Notes from Black Europe (2019) Johny Pitts Johny Pitts is a photographer and writer who lives in the north of England who set out to explore "black Europe from the street up" those districts within European cities that, although they were once 'white spaces' in the past, they are now occupied by Black people. Unhappy with the framing of the Black experience back home in post-industrial Sheffield, Pitts decided to become a nomad and goes abroad to seek out the sense of belonging he cannot find in post-Brexit Britain, and Afropean details his journey through Paris, Brussels, Lisbon, Berlin, Stockholm and Moscow. However, Pitts isn't just avoiding the polarisation and structural racism embedded in contemporary British life. Rather, he is seeking a kind of super-national community that transcends the reductive and limiting nationalisms of all European countries, most of which have based their national story on a self-serving mix of nostalgia and postcolonial fairy tales. Indeed, the term 'Afropean' is the key to understanding the goal of this captivating memoir. Pitts writes at the beginning of this book that the word wasn't driven only as a response to the crude nativisms of Nigel Farage and Marine Le Pen, but that it:
encouraged me to think of myself as whole and unhyphenated. [ ] Here was a space where blackness was taking part in shaping European identity at large. It suggested the possibility of living in and with more than one idea: Africa and Europe, or, by extension, the Global South and the West, without being mixed-this, half-that or black-other. That being black in Europe didn t necessarily mean being an immigrant.
In search of this whole new theory of home, Pitts travels to the infamous banlieue of Clichy-sous-Bois just to the East of Paris, thence to Matong in Brussels, as well as a quick and abortive trip into Moscow and other parallel communities throughout the continent. In these disparate environs, Pitts strikes up countless conversations with regular folk in order to hear their quotidian stories of living, and ultimately to move away from the idea that Black history is defined exclusively by slavery. Indeed, to Pitts, the idea of race is one that ultimately restricts one's humanity; the concept "is often forced to embody and speak for certain ideas, despite the fact it can't ever hold in both hands the full spectrum of a human life and the cultural nuances it creates." It's difficult to do justice to the effectiveness of the conversations Pitts has throughout his travels, but his shrewd attention to demeanour, language, raiment and expression vividly brings alive the people he talks to. Of related interest to fellow Brits as well are the many astute observations and comparisons with Black and working-class British life. The tone shifts quite often throughout this book. There might be an amusing aside one minute, such as the portrait of an African American tourist in Paris to whom "the whole city was a film set, with even its homeless people appearing to him as something oddly picturesque." But the register abruptly changes when he visits Clichy-sous-Bois on an anniversary of important to the area, and an element of genuine danger is introduced when Johny briefly visits Moscow and barely gets out alive. What's especially remarkable about this book is there is a freshness to Pitt s treatment of many well-worn subjects. This can be seen in his account of Belgium under the reign of Leopold II, the history of Portuguese colonialism (actually mostly unknown to me), as well in the way Pitts' own attitude to contemporary anti-fascist movements changes throughout an Antifa march. This chapter was an especial delight, and not only because it underlined just how much of Johny's trip was an inner journey of an author willing have his mind changed. Although Johny travels alone throughout his journey, in the second half of the book, Pitts becomes increasingly accompanied by a number of Black intellectuals by the selective citing of Frantz Fanon and James Baldwin and Caryl Phillips. (Nevertheless, Jonny has also brought his camera for the journey as well, adding a personal touch to this already highly-intimate book.) I suspect that his increasing exercise of Black intellectual writing in the latter half of the book may be because Pitts' hopes about 'Afropean' existence ever becoming a reality are continually dashed and undercut. The unity among potential Afropeans appears more-and-more unrealisable as the narrative unfolds, the various reasons of which Johny explores both prosaically and poetically. Indeed, by the end of the book, it's unclear whether Johny has managed to find what he left the shores of England to find. But his mix of history, sociology and observation of other cultures right on my doorstep was something of a revelation to me.

Orwell's Roses (2021) Rebecca Solnit Orwell s Roses is an alternative journey through the life and afterlife of George Orwell, reimaging his life primarily through the lens of his attentiveness to nature. Yet this framing of the book as an 'alternative' history is only revisionist if we compare it to the usual view of Orwell as a bastion of 'free speech' and English 'common sense' the roses of the title of this book were very much planted by Orwell in his Hertfordshire garden in 1936, and his yearning of nature one was one of the many constants throughout his life. Indeed, Orwell wrote about wildlife and outdoor life whenever he could get away with it, taking pleasure in a blackbird's song and waxing nostalgically about the English countryside in his 1939 novel Coming Up for Air (reviewed yesterday).
By sheer chance, I actually visited this exact garden immediately to the publication of this book
Solnit has a particular ability to evince unexpected connections between Orwell and the things he was writing about: Joseph Stalin's obsession with forcing lemons to grow in ludicrously cold climates; Orwell s slave-owning ancestors in Jamaica; Jamaica Kincaid's critique of colonialism in the flower garden; and the exploitative rose industry in Colombia that supplies the American market. Solnit introduces all of these new correspondences in a voice that feels like a breath of fresh air after decades of stodgy Orwellania, and without lapsing into a kind of verbal soft-focus. Indeed, the book displays a marked indifference towards the usual (male-centric) Orwell fandom. Her book draws to a close with a rereading of the 'dystopian' Nineteen Eighty-Four that completes her touching portrait of a more optimistic and hopeful Orwell, as well as a reflection on beauty and a manifesto for experiencing joy as an act of resistance.

The Disaster Artist (2013) Greg Sestero & Tom Bissell For those not already in the know, The Room was a 2003 film by director-producer-writer-actor Tommy Wiseau, an inscrutable Polish immigr with an impenetrable background, an idiosyncratic choice of wardrobe and a mysterious large source of income. The film, which centres on a melodramatic love triangle, has since been described by several commentators and publications as one of the worst films ever made. Tommy's production completely bombed at the so-called 'box office' (the release was actually funded entirely by Wiseau personally), but the film slowly became a favourite at cult cinema screenings. Given Tommy's prominent and central role in the film, there was always an inherent cruelty involved in indulging in the spectacle of The Room the audience was laughing because the film was astonishingly bad, of course, but Wiseau infused his film with sincere earnestness that in a heartless twist of irony may be precisely why it is so terrible to begin with. Indeed, it should be stressed that The Room is not simply a 'bad' film, and therefore not worth paying any attention to: it is uncannily bad in a way that makes it eerily compelling to watch. It unintentionally subverts all the rules of filmmaking in a way that captivates the attention. Take this representative example:
This thirty-six-second scene showcases almost every problem in The Room: the acting, the lighting, the sound design, the pacing, the dialogue and that this unnecessary scene (which does not advance the plot) even exists in the first place. One problem that the above clip doesn't capture, however, is Tommy's vulnerable ego. (He would later make the potentially conflicting claims that The Room was both an ironic cult success and that he is okay with people interpreting it sincerely). Indeed, the filmmaker's central role as Johnny (along with his Willy-Wonka meets Dracula persona) doesn't strike viewers as yet another vanity project, it actually asks more questions than it answers. Why did Tommy even make this film? What is driving him psychologically? And why and how? is he so spellbinding? On the surface, then, 2013's The Disaster Artist is a book about the making of one the strangest films ever made, written by The Room's co-star Greg Sestero and journalist Tom Bissell. Naturally, you learn some jaw-dropping facts about the production and inspiration of the film, the seed of which was planted when Greg and Tommy went to see an early screening of The Talented Mr Ripley (1999). It turns out that Greg's character in The Room is based on Tommy's idiosyncratic misinterpretation of its plot, extending even to the character's name Mark who, in textbook Tommy style, was taken directly (or at least Tommy believed) from one of Ripley's movie stars: "Mark Damon" [sic]. Almost as absorbing as The Room itself, The Disaster Artist is partly a memoir about Thomas P. Wiseau and his cinematic masterpiece. But it could also be described as a biography about a dysfunctional male relationship and, almost certainly entirely unconsciously, a text about the limitations of hetronormativity. It is this latter element that struck me the most whilst reading this book: if you take a step back for a moment, there is something uniquely sad about Tommy's inability to connect with others, and then, when Wiseau poured his soul into his film people just laughed. Despite the stories about his atrocious behaviour both on and off the film set, there's something deeply tragic about the whole affair. Jean-Luc Godard, who passed away earlier this year, once observed that every fictional film is a documentary of its actors. The Disaster Artist shows that this well-worn aphorism doesn't begin to cover it.

Chris Lamb: Favourite books of 2022: Classics

As a follow-up to yesterday's post detailing my favourite works of fiction from 2022, today I'll be listing my favourite fictional works that are typically filed under classics. Books that just missed the cut here include: E. M. Forster's A Room with a View (1908) and his later A Passage to India (1913), both gently nudged out by Forster's superb Howard's End (see below). Giuseppe Tomasi di Lampedusa's The Leopard (1958) also just missed out on a write-up here, but I can definitely recommend it to anyone interested in reading a modern Italian classic.

War and Peace (1867) Leo Tolstoy It's strange to think that there is almost no point in reviewing this novel: who hasn't heard of War and Peace? What more could possibly be said about it now? Still, when I was growing up, War and Peace was always the stereotypical example of the 'impossible book', and even start it was, at best, a pointless task, and an act of hubris at worst. And so there surely exists a parallel universe in which I never have and will never will read the book... Nevertheless, let us try to set the scene. Book nine of the novel opens as follows:
On the twelfth of June, 1812, the forces of Western Europe crossed the Russian frontier and war began; that is, an event took place opposed to human reason and to human nature. Millions of men perpetrated against one another such innumerable crimes, frauds, treacheries, thefts, forgeries, issues of false money, burglaries, incendiarisms and murders as in whole centuries are not recorded in the annals of all the law courts of the world, but which those who committed them did not at the time regard as being crimes. What produced this extraordinary occurrence? What were its causes? [ ] The more we try to explain such events in history reasonably, the more unreasonable and incomprehensible they become to us.
Set against the backdrop of the Napoleonic Wars and Napoleon's invasion of Russia, War and Peace follows the lives and fates of three aristocratic families: The Rostovs, The Bolkonskys and the Bezukhov's. These characters find themselves situated athwart (or against) history, and all this time, Napoleon is marching ever closer to Moscow. Still, Napoleon himself is essentially just a kind of wallpaper for a diverse set of personal stories touching on love, jealousy, hatred, retribution, naivety, nationalism, stupidity and much much more. As Elif Batuman wrote earlier this year, "the whole premise of the book was that you couldn t explain war without recourse to domesticity and interpersonal relations." The result is that Tolstoy has woven an incredibly intricate web that connects the war, noble families and the everyday Russian people to a degree that is surprising for a book started in 1865. Tolstoy's characters are probably timeless (especially the picaresque adventures and constantly changing thoughts Pierre Bezukhov), and the reader who has any social experience will immediately recognise characters' thoughts and actions. Some of this is at a 'micro' interpersonal level: for instance, take this example from the elegant party that opens the novel:
Each visitor performed the ceremony of greeting this old aunt whom not one of them knew, not one of them wanted to know, and not one of them cared about. The aunt spoke to each of them in the same words, about their health and her own and the health of Her Majesty, who, thank God, was better today. And each visitor, though politeness prevented his showing impatience, left the old woman with a sense of relief at having performed a vexatious duty and did not return to her the whole evening.
But then, some of the focus of the observations are at the 'macro' level of the entire continent. This section about cities that feel themselves in danger might suffice as an example:
At the approach of danger, there are always two voices that speak with equal power in the human soul: one very reasonably tells a man to consider the nature of the danger and the means of escaping it; the other, still more reasonably, says that it is too depressing and painful to think of the danger, since it is not in man s power to foresee everything and avert the general course of events, and it is therefore better to disregard what is painful till it comes and to think about what is pleasant. In solitude, a man generally listens to the first voice, but in society to the second.
And finally, in his lengthy epilogues, Tolstoy offers us a dissertation on the behaviour of large organisations, much of it through engagingly witty analogies. These epilogues actually turn out to be an oblique and sarcastic commentary on the idiocy of governments and the madness of war in general. Indeed, the thorough dismantling of the 'great man' theory of history is a common theme throughout the book:
During the whole of that period [of 1812], Napoleon, who seems to us to have been the leader of all these movements as the figurehead of a ship may seem to a savage to guide the vessel acted like a child who, holding a couple of strings inside a carriage, thinks he is driving it. [ ] Why do [we] all speak of a military genius ? Is a man a genius who can order bread to be brought up at the right time and say who is to go to the right and who to the left? It is only because military men are invested with pomp and power and crowds of sychophants flatter power, attributing to it qualities of genius it does not possess.
Unlike some other readers, I especially enjoyed these diversions into the accounting and workings of history, as well as our narrow-minded way of trying to 'explain' things in a singular way:
When an apple has ripened and falls, why does it fall? Because of its attraction to the earth, because its stalk withers, because it is dried by the sun, because it grows heavier, because the wind shakes it, or because the boy standing below wants to eat it? Nothing is the cause. All this is only the coincidence of conditions in which all vital organic and elemental events occur. And the botanist who finds that the apple falls because the cellular tissue decays and so forth is equally right with the child who stands under the tree and says the apple fell because he wanted to eat it and prayed for it.
Given all of these serious asides, I was also not expecting this book to be quite so funny. At the risk of boring the reader with citations, take this sarcastic remark about the ineptness of medicine men:
After his liberation, [Pierre] fell ill and was laid up for three months. He had what the doctors termed 'bilious fever.' But despite the fact that the doctors treated him, bled him and gave him medicines to drink he recovered.
There is actually a multitude of remarks that are not entirely complimentary towards Russian medical practice, but they are usually deployed with an eye to the human element involved rather than simply to the detriment of a doctor's reputation "How would the count have borne his dearly loved daughter s illness had he not known that it was costing him a thousand rubles?" Other elements of note include some stunning set literary pieces, such as when Prince Andrei encounters a gnarly oak tree under two different circumstances in his life, and when Nat sha's 'Russian' soul is awakened by the strains of a folk song on the balalaika. Still, despite all of these micro- and macro-level happenings, for a long time I felt that something else was going on in War and Peace. It was difficult to put into words precisely what it was until I came across this passage by E. M. Forster:
After one has read War and Peace for a bit, great chords begin to sound, and we cannot say exactly what struck them. They do not arise from the story [and] they do not come from the episodes nor yet from the characters. They come from the immense area of Russia, over which episodes and characters have been scattered, from the sum-total of bridges and frozen rivers, forests, roads, gardens and fields, which accumulate grandeur and sonority after we have passed them. Many novelists have the feeling for place, [but] very few have the sense of space, and the possession of it ranks high in Tolstoy s divine equipment. Space is the lord of War and Peace, not time.
'Space' indeed. Yes, potential readers should note the novel's great length, but the 365 chapters are actually remarkably short, so the sensation of reading it is not in the least overwhelming. And more importantly, once you become familiar with its large cast of characters, it is really not a difficult book to follow, especially when compared to the other Russian classics. My only regret is that it has taken me so long to read this magnificent novel and that I might find it hard to find time to re-read it within the next few years.

Coming Up for Air (1939) George Orwell It wouldn't be a roundup of mine without at least one entry from George Orwell, and, this year, that place is occupied by a book I hadn't haven't read in almost two decades Still, the George Bowling of Coming Up for Air is a middle-aged insurance salesman who lives in a distinctly average English suburban row house with his nuclear family. One day, after winning some money on a bet, he goes back to the village where he grew up in order to fish in a pool he remembers from thirty years before. Less important than the plot, however, is both the well-observed remarks and scathing criticisms that Bowling has of the town he has returned to, combined with an ominous sense of foreboding before the Second World War breaks out. At several times throughout the book, George's placid thoughts about his beloved carp pool are replaced by racing, anxious thoughts that overwhelm his inner peace:
War is coming. In 1941, they say. And there'll be plenty of broken crockery, and little houses ripped open like packing-cases, and the guts of the chartered accountant's clerk plastered over the piano that he's buying on the never-never. But what does that kind of thing matter, anyway? I'll tell you what my stay in Lower Binfield had taught me, and it was this. IT'S ALL GOING TO HAPPEN. All the things you've got at the back of your mind, the things you're terrified of, the things that you tell yourself are just a nightmare or only happen in foreign countries. The bombs, the food-queues, the rubber truncheons, the barbed wire, the coloured shirts, the slogans, the enormous faces, the machine-guns squirting out of bedroom windows. It's all going to happen. I know it - at any rate, I knew it then. There's no escape. Fight against it if you like, or look the other way and pretend not to notice, or grab your spanner and rush out to do a bit of face-smashing along with the others. But there's no way out. It's just something that's got to happen.
Already we can hear psychological madness that underpinned the Second World War. Indeed, there is no great story in Coming Up For Air, no wonderfully empathetic characters and no revelations or catharsis, so it is impressive that I was held by the descriptions, observations and nostalgic remembrances about life in modern Lower Binfield, its residents, and how it has changed over the years. It turns out, of course, that George's beloved pool has been filled in with rubbish, and the village has been perverted by modernity beyond recognition. And to cap it off, the principal event of George's holiday in Lower Binfield is an accidental bombing by the British Royal Air Force. Orwell is always good at descriptions of awful food, and this book is no exception:
The frankfurter had a rubber skin, of course, and my temporary teeth weren't much of a fit. I had to do a kind of sawing movement before I could get my teeth through the skin. And then suddenly pop! The thing burst in my mouth like a rotten pear. A sort of horrible soft stuff was oozing all over my tongue. But the taste! For a moment I just couldn't believe it. Then I rolled my tongue around it again and had another try. It was fish! A sausage, a thing calling itself a frankfurter, filled with fish! I got up and walked straight out without touching my coffee. God knows what that might have tasted of.
Many other tell-tale elements of Orwell's fictional writing are in attendance in this book as well, albeit worked out somewhat less successfully than elsewhere in his oeuvre. For example, the idea of a physical ailment also serving as a metaphor is present in George's false teeth, embodying his constant preoccupation with his ageing. (Readers may recall Winston Smith's varicose ulcer representing his repressed humanity in Nineteen Eighty-Four). And, of course, we have a prematurely middle-aged protagonist who almost but not quite resembles Orwell himself. Given this and a few other niggles (such as almost all the women being of the typical Orwell 'nagging wife' type), it is not exactly Orwell's magnum opus. But it remains a fascinating historical snapshot of the feeling felt by a vast number of people just prior to the Second World War breaking out, as well as a captivating insight into how the process of nostalgia functions and operates.

Howards End (1910) E. M. Forster Howards End begins with the following sentence:
One may as well begin with Helen s letters to her sister.
In fact, "one may as well begin with" my own assumptions about this book instead. I was actually primed to consider Howards End a much more 'Victorian' book: I had just finished Virginia Woolf's Mrs Dalloway and had found her 1925 book at once rather 'modern' but also very much constrained by its time. I must have then unconsciously surmised that a book written 15 years before would be even more inscrutable, and, with its Victorian social mores added on as well, Howards End would probably not undress itself so readily in front of the reader. No doubt there were also the usual expectations about 'the classics' as well. So imagine my surprise when I realised just how inordinately affable and witty Howards End turned out to be. It doesn't have that Wildean shine of humour, of course, but it's a couple of fields over in the English countryside, perhaps abutting the more mordant social satires of the earlier George Orwell novels (see Coming Up for Air above). But now let us return to the story itself. Howards End explores class warfare, conflict and the English character through a tale of three quite different families at the beginning of the twentieth century: the rich Wilcoxes; the gentle & idealistic Schlegels; and the lower-middle class Basts. As the Bloomsbury Group Schlegel sisters desperately try to help the Basts and educate the rich but close-minded Wilcoxes, the three families are drawn ever closer and closer together. Although the whole story does, I suppose, revolve around the house in the title (which is based on the Forster's own childhood home), Howards End is perhaps best described as a comedy of manners or a novel that shows up the hypocrisy of people and society. In fact, it is surprising how little of the story actually takes place in the eponymous house, with the overwhelming majority of the first half of the book taking place in London. But it is perhaps more illuminating to remark that the Howards End of the book is a house that the Wilcoxes who own it at the start of the novel do not really need or want. What I particularly liked about Howards End is how the main character's ideals alter as they age, and subsequently how they find their lives changing in different ways. Some of them find themselves better off at the end, others worse. And whilst it is also surprisingly funny, it still manages to trade in heavier social topics as well. This is apparent in the fact that, although the characters themselves are primarily in charge of their own destinies, their choices are still constrained by the changing world and shifting sense of morality around them. This shouldn't be too surprising: after all, Forster's novel was published just four years before the Great War, a distinctly uncertain time. Not for nothing did Virginia Woolf herself later observe that "on or about December 1910, human character changed" and that "all human relations have shifted: those between masters and servants, husbands and wives, parents and children." This process can undoubtedly be seen rehearsed throughout Forster's Howards End, and it's a credit to the author to be able to capture it so early on, if not even before it was widespread throughout Western Europe. I was also particularly taken by Forster's fertile use of simile. An extremely apposite example can be found in the description Tibby Schlegel gives of his fellow Cambridge undergraduates. Here, Timmy doesn't want to besmirch his lofty idealisation of them with any banal specificities, and wishes that the idea of them remain as ideal Platonic forms instead. Or, as Forster puts it, to Timmy it is if they are "pictures that must not walk out of their frames." Wilde, at his most weakest, is 'just' style, but Forster often deploys his flair for a deeper effect. Indeed, when you get to the end of this section mentioning picture frames, you realise Forster has actually just smuggled into the story a failed attempt on Tibby's part to engineer an anonymous homosexual encounter with another undergraduate. It is a credit to Forster's sleight-of-hand that you don't quite notice what has just happened underneath you and that the books' reticence to honestly describe what has happened is thus structually analogus Tibby's reluctance to admit his desires to himself. Another layer to the character of Tibby (and the novel as a whole) is thereby introduced without the imposition of clumsy literary scaffolding. In a similar vein, I felt very clever noticing the arch reference to Debussy's Pr lude l'apr s-midi d'un faune until I realised I just fell into the trap Forster set for the reader in that I had become even more like Tibby in his pseudo-scholarly views on classical music. Finally, I enjoyed that each chapter commences with an ironic and self-conscious bon mot about society which is only slightly overblown for effect. Particularly amusing are the ironic asides on "women" that run through the book, ventriloquising the narrow-minded views of people like the Wilcoxes. The omniscient and amiable narrator of the book also recalls those ironically distant voiceovers from various French New Wave films at times, yet Forster's narrator seems to have bigger concerns in his mordant asides: Forster seems to encourage some sympathy for all of the characters even the more contemptible ones at their worst moments. Highly recommended, as are Forster's A Room with a View (1908) and his slightly later A Passage to India (1913).

The Good Soldier (1915) Ford Madox Ford The Good Soldier starts off fairly simply as the narrator's account of his and his wife's relationship with some old friends, including the eponymous 'Good Soldier' of the book's title. It's an experience to read the beginning of this novel, as, like any account of endless praise of someone you've never met or care about, the pages of approving remarks about them appear to be intended to wash over you. Yet as the chapters of The Good Soldier go by, the account of the other characters in the book gets darker and darker. Although the author himself is uncritical of others' actions, your own critical faculties are slowgrly brought into play, and you gradully begin to question the narrator's retelling of events. Our narrator is an unreliable narrator in the strict sense of the term, but with the caveat that he is at least is telling us everything we need to know to come to our own conclusions. As the book unfolds further, the narrator's compromised credibility seems to infuse every element of the novel even the 'Good' of the book's title starts to seem like a minor dishonesty, perhaps serving as the inspiration for the irony embedded in the title of The 'Great' Gatsby. Much more effectively, however, the narrator's fixations, distractions and manner of speaking feel very much part of his dissimulation. It sometimes feels like he is unconsciously skirting over the crucial elements in his tale, exactly like one does in real life when recounting a story containing incriminating ingredients. Indeed, just how much the narrator is conscious of his own concealment is just one part of what makes this such an interesting book: Ford Madox Ford has gifted us with enough ambiguity that it is also possible that even the narrator cannot find it within himself to understand the events of the story he is narrating. It was initially hard to believe that such a carefully crafted analysis of a small group of characters could have been written so long ago, and despite being fairly easy to read, The Good Soldier is an almost infinitely subtle book even the jokes are of the subtle kind and will likely get a re-read within the next few years.

Anna Karenina (1878) Leo Tolstoy There are many similar themes running through War and Peace (reviewed above) and Anna Karenina. Unrequited love; a young man struggling to find a purpose in life; a loving family; an overwhelming love of nature and countless fascinating observations about the minuti of Russian society. Indeed, rather than primarily being about the eponymous Anna, Anna Karenina provides a vast panorama of contemporary life in Russia and of humanity in general. Nevertheless, our Anna is a sophisticated woman who abandons her empty existence as the wife of government official Alexei Karenin, a colourless man who has little personality of his own, and she turns to a certain Count Vronsky in order to fulfil her passionate nature. Needless to say, this results in tragic consequences as their (admittedly somewhat qualified) desire to live together crashes against the rocks of reality and Russian society. Parallel to Anna's narrative, though, Konstantin Levin serves as the novel's alter-protagonist. In contrast to Anna, Levin is a socially awkward individual who straddles many schools of thought within Russia at the time: he is neither a free-thinker (nor heavy-drinker) like his brother Nikolai, and neither is he a bookish intellectual like his half-brother Serge. In short, Levin is his own man, and it is generally agreed by commentators that he is Tolstoy's surrogate within the novel. Levin tends to come to his own version of an idea, and he would rather find his own way than adopt any prefabricated view, even if confusion and muddle is the eventual result. In a roughly isomorphic fashion then, he resembles Anna in this particular sense, whose story is a counterpart to Levin's in their respective searches for happiness and self-actualisation. Whilst many of the passionate and exciting passages are told on Anna's side of the story (I'm thinking horse race in particular, as thrilling as anything in cinema ), many of the broader political thoughts about the nature of the working classes are expressed on Levin's side instead. These are stirring and engaging in their own way, though, such as when he joins his peasants to mow the field and seems to enter the nineteenth-century version of 'flow':
The longer Levin mowed, the more often he felt those moments of oblivion during which it was no longer his arms that swung the scythe, but the scythe itself that lent motion to his whole body, full of life and conscious of itself, and, as if by magic, without a thought of it, the work got rightly and neatly done on its own. These were the most blissful moments.
Overall, Tolstoy poses no didactic moral message towards any of the characters in Anna Karenina, and merely invites us to watch rather than judge. (Still, there is a hilarious section that is scathing of contemporary classical music, presaging many of the ideas found in Tolstoy's 1897 What is Art?). In addition, just like the earlier War and Peace, the novel is run through with a number of uncannily accurate observations about daily life:
Anna smiled, as one smiles at the weaknesses of people one loves, and, putting her arm under his, accompanied him to the door of the study.
... as well as the usual sprinkling of Tolstoy's sardonic humour ("No one is pleased with his fortune, but everyone is pleased with his wit."). Fyodor Dostoyevsky, the other titan of Russian literature, once described Anna Karenina as a "flawless work of art," and if you re only going to read one Tolstoy novel in your life, it should probably be this one.

Next.
