Russ Allbery: 2016 Book Reading in Review

So, I did not accomplish my reading goal for 2016 (reading and reviewing more books in 2016 than I did in 2015). Many things contributed to that, but the root cause was that I didn't make enough time for reading. Much of the time that could have gone to reading went to playing Hearthstone (a good thing) and obsessing over the 2016 US election (mostly a waste of time and particularly energy, although I'm not sure I could have stopped). That said, I did get quite a lot of reading done at the end of the year, and I'm hoping to keep up that momentum for next year. In 2016, I did a lot of re-reading and comfort reading. I'm probably going to continue with some of the re-reading in 2017, since I'm enjoying it, but my reading goal for the year is to get back to reading award nominees and previous award winners. There's so much great new stuff being published that I want to discover. I'm not going to set an explicit goal around number of books, but I am going to make an effort to carve out more time in my schedule for reading books (and less for reading on-line news). This was another year with two 10 out of 10 books. One of them was a re-read: Lord of Emperors, the second book of Guy Gavriel Kay's Sarantine Mosaic. (I also re-read the first book this year, Sailing to Sarantium, and gave it a 9.) I like nearly all of Kay's historical fantasies, but this duology is one of my personal favorites. The second 10 out of 10 book was a complete surprise: A Man Called Ove by Fredrik Backman (translated by Henning Koch). My mother found this book and suggested it to me, and I loved every moment of it. I will definitely be reading more of Backman's work. There were two more fiction standouts this year: Digger by Ursula Vernon, and The Philosopher Kings by Jo Walton. The first is a graphic novel about a wombat who is trying to make her way home from an unexpected detour into a mess of magic and gods. The second is the middle book in a trilogy about an attempt to construct Plato's Just City and all of the philosophical and social problems that ensue (with some bonus science fiction and fantasy elements). Both of them are excellent. Walton is consistently one of my favorite authors, and Ursula Vernon was my great discovery of a new author to read this year. (Not that I've followed through on that much, the year in reading being what it was, but I will be doing so.) My favorite non-fiction book of the year continues my interest in time management in general and Mark Forster's approaches in particular. Secrets of Productive People was the last book I reviewed this year (just a coincidence, not any intentional attempt to set things up for next year) and the best version of his overall approach to date. If you've not read any of Forster based on my previous recommendations, this is a good place to start. Also worth mentions were Jeffrey Toobin's The Run of His Life, on the O.J. Simpson case, and Andrew Groen's The Empires of EVE, on the history of player empires in the EVE Online MMORPG. I Kickstarted the latter and didn't regret it. The full analysis includes some additional personal reading statistics, probably only of interest to me.

Russ Allbery: Review: Secrets of Productive People

Review: Secrets of Productive People, by Mark Forster
Publisher: Teach Yourself
Copyright: 2015
ISBN: 1-4736-0885-6
Format: Kindle
Pages: 289
Regular readers of my reviews will know that Mark Forster is my favorite writer on time management and productivity. That's mostly because of his flexible toolkit approach that talks about theory and overall goals and then describes multiple ways to get there, rather than presenting a single system that will solve all your problems. There are a lot of writers who explain productivity tips and tricks or describe systems that work for them. There are fewer who can explain why those tricks work (and why they sometimes don't work), and even fewer who can put them into a meaningful analytical framework for thinking about productivity. Forster has several books, but they're a mixed bag. His clearest and most coherent book prior to this one was Do It Tomorrow. Secrets of Productive People is organized differently, chopped up in to small bite-sized chunks with synopses to an extent that it felt a bit choppy to me, but apart from that it's the closest I've seen to an updating of Do It Tomorrow. His other books can be slight (The Pathway to Awesomeness) or downright weird (How to Make Your Dreams Come True). I still have a soft spot for Do It Tomorrow, and I like how it was organized a bit better than this one, but I think Secrets of Productive People has become my new recommendation for where to start with Forster. Secrets of Productive People is divided into five sections: The basics of productivity, the productive attitude, productive projects, aids to productivity, and productivity in action. Each part is divided into several small chapters, which open with a generous helping of quotes about some productivity topic (and I'm going to go back and save some of those), present some easily-digestible related set of thoughts (usually with an exercise), and conclude with a summary. Each chapter is about the length of a long blog post. I think this structure interferes with developing an idea at greater length, but it does make for good reading material in an environment where you're regularly interrupted or only have five or ten minutes. I think I've mentioned in every review that Forster won me over by being willing to talk about the problems with attempting to do too much, not just presenting a system to allow one to accomplish more. Some other books, such as David Allen's famous Getting Things Done, seem to assume you already know what you need to get done, or will easily be able to figure that out when you think for a while, and just need a system to manage all the things you've decided to do. Forster takes the opposite approach, and this book is the clearest yet on this point: most productivity problems are not from being insufficiently efficient, but from doing the wrong things and too many things. You don't need more time; everyone gets the same amount of time. You need to do the right things with the time you have, and that usually means doing fewer things. Readers of Forster's previous books will recognize many of the themes here. Some of the techniques from Do It Tomorrow and some of the exercises from Get Everything Done show up again here. But Forster has streamlined and focused the advice, discarded some things, made his task management recommendations less elaborate and more focused, and spends much more time hammering home the point that the only prioritization that really matters is whether you commit to doing something or don't. The specific task management system he recommends here is one of the variations he's been talking about in his blog and is much simpler than the Do It Tomorrow system: pick five tasks, work on them until you've finished three of them, and then refill to five tasks. I've been using it since reading this book, replacing one of Forster's more elaborate systems from his blog, and it's surprisingly effective. He breaks down in some detail why this works and how to extract additional useful feedback information from it, and now I want to do some of the additional exercises he describes. (That said, I'm still dubious about his advice to not keep any larger to-do list and only rely on your analysis at the time of refilling the list to decide what to do. I use this system with a supplemental, longer list of ideas for future tasks, and that works better for me, although I do have to fight forming a sense of obligation about the things on the longer list. David Allen still has a point that if you don't write down a complete inventory of the things you're worrying about, your brain will try to obsess over them to keep from forgetting them.) The productive projects section told me some things I needed to hear about time commitments. Projects take regular, focused attention, and starting numerous things without giving them that attention is much worse than doing far fewer things but doing them regularly and reliably. I think Forster's coaching on focus and persistence is very valuable; the trick, of course, is building up your willpower for it and learning to say no. This is in-line with recent psychological analysis of multi-tasking and its various negative effects. The working to-do list capped at five things provides enough variety to mentally shift gears if one runs out of steam on some specific project while maintaining enough focus to not leave things behind half-done. The productivity aids section provides a more random collection of tips and tricks, many of which I've seen before in his previous books. I've mostly not tried these, so can't say much about how effective they are, but Forster's ideas almost always sound interesting and plausible. I thought the weakest part of the book was the last section, on applied productivity. Here, Forster takes various life areas (exercise, parenting, finances, writing, etc.) and talks about how the principles of this book can be applied to them. Each area could be a book in itself, and the short essay format of these chapters doesn't do justice to large topics. The result is a rather repetitive section that just stresses analysis, metrics, and repeated, focused attention all valid points, but ones you can pick up from the previous chapters. I don't think these case studies added much value. Do It Tomorrow is still my favorite Forster book to read, but I think Secrets of Productive People is now the best and most polished overview of his time management and productivity approach. If you're interested in this topic and not already sick of Forster from my previous recommendations, this would be a great place to start. I got a lot out of it even with all the time management reading I've previously done, and will probably re-read sections of it and try more of the exercises. Rating: 9 out of 10

Sean Whitton: Burkeman on time management

Burkeman: Why time management is ruining our lives Over the past semester I ve been trying to convince one graduate student and one professor in my department to use Inbox Zero to get a better handle on their e-mail inboxes. The goal is not to be more productive. The two of them get far more academic work done than I do. However, both of them are far more stressed than I am. And in the case of the graduate student, I have to add items to my own to-do list to chase up e-mails that I ve sent him, which only spreads this stress and tension around. The graduate student sent me this essay by Oliver Burkeman about how these techniques can backfire, creating more stress, tension and anxiety. It seems to me that this happens when we think of these techniques as having anything to do with productivity. Often people will say use this technique and you ll be less stressed, more productive, and even more productive because you re less stressed. Why not just say use this technique and you ll be less anxious and stressed ? This is a refusal to treat lower anxiety as merely a means to some further end. People can autonomously set their own ends, and they ll probably do a better job of this when they re less anxious. Someone offering a technique to help with their sense of being overwhelmed need not tell them what to do with their new calm. It might be argued that this response to Burkeman fails to address the huge sense of obligation that an e-mail inbox can generate. Perhaps the only sane response to this infinite to-do list is to let it pile up. If we follow a technique like Inbox Zero, don t we invest our inbox with more importance than it has? Like a lot of areas of life, the issue is that the e-mails that will advance truly valuable projects and relationships, projects of both ourselves and of others, are mixed in with reams of stuff that doesn t matter. We face this situation whenever we go into a supermarket, or wonder what to do during an upcoming vacation. In all these situations, we have a responsibility to learn how to filter the important stuff out, just as we have a responsibility to avoid reading celebrity gossip columns when we are scanning through a newspaper. Inbox Zero is a technique to do that filtering in the case of e-mail. Just letting our inbox pile up is an abdication of responsibility, rather than an intelligent response to a piece of technology that most of the world abuses.

Russ Allbery: Review: Magician's Gambit

Review: Magician's Gambit, by David Eddings
Series: The Belgariad #3
Publisher: Del Rey
Copyright: June 1983
Printing: February 1990
ISBN: 0-345-33545-7
Format: Mass market
Pages: 305
Magician's Gambit is the third book of the Belgariad, and although it's the best, you probably can't start here. Too much setup has already happened by this point of the story. In retrospect, it's my memories of this book that led me to hang on to this series all these years and pick it up for a re-read. Garion has finally gotten past his whining (mostly), the party puts Ce'Nedra in a hole and leaves her there for a bunch of the book, and the characters finally do something concrete (and significant) in advancement of the plot. Eddings does a good job of avoiding the series problem of saving up all the climactic moments for the end of the story and instead adds a very good middle climax to the story that wraps up the main plot line of the first three books. I think this is also the book that best displays the interestingly quirky ways that Eddings approaches the epic fantasy genre. (Now to figure out how to talk about them without spoiling the story....) One of my favorite bits in this series is the dry voice in the back of Garion's head. I don't want to say too much about it, since discovering the nature of that voice slowly over the series is part of the fun. But this is the book where most of that mystery is revealed, and it's a rather different spin on the wise advisor trope. Garion has more than the usual number of mentor figures, and like many books of this type they function partly as plot devices to force the story down the correct path. One of the things that makes plot devices irritating is that they feel forced on the story from outside. Eddings here pulls a trick to embed that device inside the story, so it feels less like the hand of the author and more like an aspect of the mythology. I'm not sure it would work for everyone, and the execution isn't that sophisticated, but it's entertained me every time I read this series. It helps that the voice is an interesting character in its own right, and one of the few characters in the book who takes Garion seriously and explains things to him. By comparison, Belgarath and Polgara are still annoyingly high-handed and uncommunicative (particularly Polgara). Another highlight of this book is a lovely interlude in Belgarath's home, where we meet some of his colleagues (Beldin is a delight) and Garion finally starts experimenting with his own power. I mostly read this series for the supporting characters, not for Garion, who spends far too much time whining and most of the rest of the time being just neutrally there. But in this book Eddings finally gives him some moments of real awe and discovery, using one of my favorite approaches to the powerful chosen one character: making normally-hard things easy but normally-easy things unintuitive because they think about magic differently than anyone else. Most of the moments when Garion does something that shouldn't be possible are highlights. We also get nearly the final characters for Garion's band, and they're good ones. Relg is mostly amusing in some of his later reactions to specific characters and is a bit tedious in this book, but Errand is a unique idea and one of my favorite characters of the series. He fits well with the tendency of this series to not take itself, or power, or mythology, too seriously. Eddings avoids the trap of making everything Significant and Fraught; characters snark and do things on a whim, power has funny side effects, and the most powerful object in the story is treated in a way that has one both laughing and flinching at the same time. (It's a nice twist on and homage to some of the trappings around the One Ring, while making it far more light-hearted.) There are a few things I could complain about (the gender stereotyping between Garion and Ce'Nedra is so strong, for instance), but they're more minor here than in previous books. I enjoy reading about characters doing things they're very good at, and there's quite a lot of that here. (That said, I do feel like I should mention somewhere that one of the characters is very good at killing Murgos, who are supposedly human. I suppose it wouldn't be epic fantasy without a bit of casual genocide, and to be fair the Murgos in question are mostly trying to track down and kill the party, but the way that's played partly for laughs gets distasteful if one thinks about it too much.) This series is at its best when it balances dramatic prophecy with irreverent poking, gives the protagonists moments of odd and very human joy (Garion's colt!), and celebrates the unlikely and unexpected collection of people (or fable characters) who are drawn together by the story. I think this book hits those notes well, and although the flaws of the previous books are still there, they're muted and don't get as much screen time. Instead, we get some fun foreshadowing, a sense of power and growth, a few moments of delight and awe, and a lot of the sort of exasperated wise-cracking common to experienced people who trust each other and are working together on something hard. Magician's Gambit, and this whole series, will not be to everyone's taste, but it's the first book of the series I can comfortably recommend if you like this sort of thing. Followed by Castle of Wizardry. Rating: 8 out of 10

Antoine Beaupr : My free software activities, November and December 2016

Debian Long Term Support (LTS) Those were 8th and 9th months working on Debian LTS started by Raphael Hertzog at Freexian. I had trouble resuming work in November as I had taken a long break during the month and started looking at issues only during the last week of November.

Imagemagick, again I have, again, spent a significant amount of time fighting the ImageMagick (IM) codebase. About 15 more vulnerabilities were found since the last upload, which resulted in DLA-756-1. In the advisory, I unfortunately forgot to mention CVE-2016-8677 and CVE-2016-9559, something that was noticed by my colleague Roberto after the upload... More details about the upload are available in the announcement. When you consider that I worked on IM back in october, which lead to an upload near the end of November covering around 80 more vulnerabilities, it doesn't look good for the project at all. Of the 15 vulnerabilities I worked on, only 6 had CVEs assigned and I had to request CVEs for the other 9 vulnerabilities plus 11 more that were still unassigned. This lead to the assignment of 25 distinct CVE identifiers as a lot of issues were found to be distinct enough to warrant their own CVEs. One could also question how many of those issues affect the fork, Graphicsmagick. A lot of the vulnerabilities were found through fuzzing searches that may not have been tested on Graphicsmagick. It seems clear to me that a public corpus of test data should be available to test regressions and cross-project vulnerabilities. It's already hard enough to track issues withing IM itself, I can't imagine what it would be for the fork to keep track of those issues, especially since upstream doesn't systematically request CVEs for issues that they find, a questionable practice considering the number of issues we all need to keep track of.

Nagios I have also worked on the Nagios package and produced DLA 751-1 which fixed two fairly major issues (CVE-2016-9565 and CVE-2016-9566) that could allow remote root access under certain conditions. Fortunately, the restricted permissions setup by default in the Debian package made both exploits limited to information disclosure and privilege escalation if the debug log is enabled. This says a lot about how proper Debian packaging can help in limiting the attack surface of certain vulnerabilities. It was also "interesting" to have to re-learn dpatch to add patches to the package: I regret not converting it to quilt, as the operation is simple and quilt is so much easier to use. People new to Debian packaging may be curious to learn about the staggering number of patching systems historically used in Debian. On that topic, I started a conversation about how much we want to reuse existing frameworks when we work on those odd packages, and the feedback was interesting. Basically, the answer is "it depends"...

NSS I had already worked on the package in November and continued the work in December. Most of the work was done by Raphael, which fixed a lot of issues with the test suite. I tried to wrap this up by fixing CVE-2016-9074, the build on armel and the test suite. Unfortunately, I had to stop again because I ran out of hours and the fips test suite was still failing, but fortunately Raphael was able to complete the work with DLA-759-1. As things stand now, the package is in better shape than in other suites as tests (Debian bug #806639) and autopkgtest (Debian bug #806207) are still not shipped in the sid or stable releases.

Other work For the second time, I forgot to formally assign myself a package before working on it, which meant that I wasted part of my hours working on the monit package. Those hours, of course, were not counted in my regular hours. I still spent some time reviewing mejo's patch to ensure it was done properly and it turned out we both made similar patches working independently, always a good sign. As I reported in my preliminary November report, I have also triaged issues in libxml2, ntp, openssl and tiff. Finally, I should mention my short review of the phpMyAdmin upload, among the many posts i sent to the LTS mailing list.

Other free software work One reason why I had so much trouble getting paid work done in November is that I was busy with unpaid work...

manpages.debian.org A major time hole for me was trying to tackle the manpages.debian.org service, which had been offline since August. After a thorough evaluation of the available codebases, I figured the problem space wasn't so hard and it was worth trying to do an implementation from scratch. The result is a tool called debmans. It took, obviously, way longer than I expected, as I experimented with Python libraries I had been keeping an eye on for a while. For the commanline interface, I used the click library, which is really a breeze to use, but a bit heavy for smaller scripts. For a web search service prototype, I looked at flask, which was also very interesting, as it is light and simple enough to use that I could get started quickly. It also, surprisingly, fares pretty well in the global TechEmpower benchmarking tests. Those interested in those tools may want to look at the source code, in particular the main command (using an interesting pattern itself, __main__.py) and the search prototype. Debmans is the first project for which I have tried the CII Best Practices Badge program, an interesting questionnaire to review best practices in software engineering. It is an excellent checklist I recommend every project manager and programmer to get familiar with. I still need to complete my work on Debmans: as I write this, I couldn't get access to the new server the DSA team setup for this purpose. It was a bit of a frustrating experience to wait for all the bits to get into place while I had a product ready to test. In the end, the existing manpages.d.o maintainer decided to deploy the existing codebase on the new server while the necessary dependencies are installed and accesses are granted. There's obviously still a bunch of work to be done for this to be running in production so I have postponed all this work to January. My hope is that this tool can be reused by other distributions, but after talking with Ubuntu folks, I am not holding my breath: it seems everyone has something that is "good enough" and that they don't want to break it...

Monkeysign I spent a good chunk of time giving a kick in the Monkeysign project, with the 2.2.2 release, which features contributions from two other developers, which may be a record for a single release. I am especially happy to have adopted a new code of conduct - it has been an interesting process to adapt the code of conduct for such a relatively small project. Monkeysign is becoming a bit of a template on how to do things properly for my Python projects: documentation on readthedocs.org including a code of conduct, support and contribution information, and so on. Even though the code now looks a bit old to me and I am embarrassed to read certain parts, I still think it is a solid project that is useful for a lot of people. I would love to have more time to spend on it.

LWN publishing As you may have noticed if you follow this blog, I have started publishing articles for the LWN magazine, filed here under the lwn tag. It is a way for me to actually get paid for some of my blogging work that used to be done for free. Reports like this one, for example, take up a significant amount of my time and are done without being paid. Converting parts of this work into paid work is part of my recent effort to reduce the amount of time I spend on the computer. An funny note: I always found the layout of the site to be a bit odd, until I looked at my articles posted there in a different web browser, which didn't have my normal ad blocker configuration. It turns out LWN uses ads, and Google ones too, which surprised me. I definitely didn't want to publish my work under banner ads, and will never do so on this blog. But it seems fair that, since I get paid for this work, there is some sort of revenue stream associated with it. If you prefer to see my work without ads, you can wait for it to be published here or become a subscriber which allows you to get rid of the ads on the site. My experience with LWN is great: they're great folks, and very supportive. It's my first experience with a real editor and it really pushed me in improving my writing to make better articles that I normally would here. Thanks to the LWN folks for their support! Expect more of those quality articles in 2017.

Debian packaging I have added a few packages to the Debian archive:
  • magic-wormhole: easy file-transfer tool, co-maintained with Jamie Rollins
  • slop: screenshot tool
  • xininfo: utility used by teiler
  • teiler (currently in NEW): GUI for screenshot and screencast tools
I have also updated sopel and atheme-services.

Other work Against my better judgment, I worked again on the borg project. This time I tried to improve the documentation, after a friend asked me for help on "how to make a quick backup". I realized I didn't have any good primer to send regular, non-sysadmin users to and figured that, instead of writing a new one, I could improve the upstream documentation instead. I generated a surprising 18 commits of documentation during that time, mainly to fix display issues and streamline the documentation. My final attempt at refactoring the docs eventually failed, unfortunately, again reminding me of the difficulty I have in collaborating on that project. I am not sure I succeeded in making the project more attractive to non-technical users, but maybe that's okay too: borg is a fairly advanced project and not currently aimed at such a public. This is yet another project I am thinking of creating: a metabackup program like backupninja that would implement the vision created by liw in his A vision for backups in Debian post, which was discarded by the Borg project. Github also tells me that I have opened 19 issues in 14 different repositories in November. I would like to particularly bring your attention to the linkchecker project which seems to be dead upstream and for which I am looking for collaborators in order to create a healthy fork. Finally, I started on reviving the stressant project and changing all my passwords, stay tuned for more!

Chris Lamb: My favourite books of 2016

Whilst I managed to read almost sixty books in 2016 here are ten of my favourites in no particular order. Disappointments this year include Stewart Lee's Content Provider (nothing like his stand-up), Christopher Hitchens' And Yet (his best essays are already published) and Heinlein's Stranger in a Strange Land (great exposition, bizarre conclusion). The worst book I finished, by far, was Mark Edward's Follow You Home.





https://images-eu.ssl-images-amazon.com/images/P/B010EAQLV2.01._PC__.jpg Animal QC Gary Bell, QC Subtitled My Preposterous Life, this rags-to-riches story about a working-class boy turned eminent lawyer would be highly readable as a dry and factual account but I am compelled to include it here for its extremely entertaining style of writing. Full of unsurprising quotes that take one unaware: would you really expect a now-Queen's Counsel to "heartily suggest that if you find yourself suffering from dysentery in foreign climes you do not medicate it with lobster thermidor and a bottle of Ecuadorian red?" A real good yarn.
https://images-eu.ssl-images-amazon.com/images/P/B0196HJ6OS.01._PC__.jpg So You've Been Publically Shamed Jon Ronson The author was initially recommended to me by Brad but I believe I started out with the wrong book. In fact, I even had my doubts about this one, prematurely judging from the title that it was merely cashing-in on a fairly recent internet phenomenon like his more recent shallow take on Trump and the alt-Right but in the end I read Publically Shamed thrice in quick succession. I would particularly endorse the audiobook version: Ronson's deadpan drawl suits his writing perfectly.
https://images-eu.ssl-images-amazon.com/images/P/B00IX49OS4.01._PC__.jpg The Obstacle is the Way Ryan Holiday Whilst everyone else appears to be obligated to include Ryan's recent Ego is the Enemy in their Best of 2016 lists I was actually taken by his earlier "introduction by stealth" to stoic philosophy. Certainly not your typical self-help book, this is "a manual to turn to in troubling times". Returning to this work at least three times over the year even splashing out on the audiobook at some point I feel like I learned a great deal, although it is now difficult to pinpoint exactly what. Perhaps another read in 2017 is thus in order
https://images-eu.ssl-images-amazon.com/images/P/071563335X.01._PC__.jpg Layer Cake J.J. Connolly To judge a book in comparison to the film is to do both a disservice, but reading the book of Layer Cake really underscored just how well the film played to the strengths of that medium. All of the aspects that would not have worked had been carefully excised from the screenplay, ironically leaving more rewarding "layers" for readers attempting the book. A parallel adaption here might be No Country for Old Men - I would love to read (or write) a comparative essay between these two adaptions although McCarthy's novel is certainly the superior source material.
https://images-eu.ssl-images-amazon.com/images/P/B00G1SRB6Q.01._PC__.jpg Lying Sam Harris I've absorbed a lot of Sam Harris's uvre this year in the form of his books but moreover via his compelling podcast. I'm especially fond of Waking Up on spirituality without religion and would rank that as my favourite work of his. Lying is a comparatively short read, more of a long essay in fact, where he argues that we can radically simplify our lives by merely telling the truth in situations where others invariably lie. Whilst it would take a brave soul to adopt his approach his case is superlatively well-argued and a delight to read.
https://images-eu.ssl-images-amazon.com/images/P/0140442103.01._PC__.jpg Letters from a Stoic Seneca

Great pleasure is to be found not only in keeping up an old and established friendship but also in beginning and building up a new one. Reading this in a beautifully svelte hardback, I tackled a randomly-chosen letter per day rather than attempting to read it cover-to-cover. Breaking with a life-long tradition, I even decided to highlight sections in pen so I could return to them at ease. I hope it's not too hackneyed to claim I gained a lot from "building up" a relationship with this book. Alas, it is one of those books that is too easy to recommend given that it might make one appear wise and learned, but if you find yourself in a slump, either in life or in your reading habits, it certainly has my approval.


https://images-eu.ssl-images-amazon.com/images/P/B00BHD3TIE.01._PC__.jpg Solo: A James Bond Novel William Boyd I must have read all of the canonical Fleming novels as a teenager and Solo really rewards anyone who has done so. It would certainly punish anyone expecting a Goldeneye or at least be a little too foreign to be enjoyed. Indeed, its really a pastiche of these originals, both in terms of the time period, general tone (Bond is more somber; more vulnerable) and in various obsessions of Fleming's writing, such as the overly-detailed description of the gambling and dining tables. In this universe, 007's restaurant expenses probably contributed signifcantly to the downfall of the British Empire, let alone his waistline. Bond flicking through a ornithological book at one point was a cute touch
https://images-eu.ssl-images-amazon.com/images/P/B019MMUA8S.01._PC__.jpg The Subtle Art of Not Giving A F*ck Mark Manson Certainly a wildcard to include here and not without its problems, The Subtle Art is a curious manifesto on how to approach life. Whilst Manson expouses an age-old philosophy of grounding yourself and ignoring the accumulation of flatscreen TVs, etc. he manages to do so in a fresh and provocative "21st-centry gonzo" style. Highly entertaining, at one point the author posits an alternative superhero ("Disappointment Panda") that dishes out unsolicited and uncomfortable truths to strangers before simply walking away: "You know, if you make more money, that s not going to make your kids love you," or: "What you consider friendship is really just your constant attempts to impress people." Ouch.

I might thus be giving the book more credit due to this highly satisfying connection but I think it stands alone as a superlative political page-turner and is still approachable outside the machinations of the Cold War.

Alas, it appears the rest of the author's output is unfortunately in the same vein (laywers, etc.) so I am hesitant to immediately begin others but judging from various lists online I am glad I approached this one first.

Like any good musical composition, one is always rewarded by returning to a book and I took great delight in uncovering more symbolism throughout (such as noticing that one of the first words Blackthorne learns in Japanese is "truth") but also really savouring the tragic arcs that run throughout the novel, some beautiful phrases ("The day seemed to lose its warmth ") and its wistful themes of inevitability and karma.

Russ Allbery: Review: Queen of Sorcery

Review: Queen of Sorcery, by David Eddings
Series: The Belgariad #2
Publisher: Del Rey

Pages: 322
Queen of Sorcery is the second book in the Belgariad, which is a "one story in five books" sort of series. You could probably take a chance on skipping Pawn of Prophecy, since it's not a very good book, but some parts of the story may be confusing without it. We're now getting into the part of the series where I can start saying some nice things about it, so I should put that in context and not get expectations too high. The Belgariad as a series is fully invested in the stock symbols and stereotypes of Tolkien-derivative fantasy. White is good; black is bad. West is good; east is bad. People are very neatly divided into countries, and national traits are exceptionally strong. The Murgos, the people who serve (although "under the thumb of" would be more accurate, Eddings doesn't spend much time thinking about the difference) the Big Bad of the series, are basically orcs, for all that they're theoretically human. With an unsympathetic reading, it's very easy to see the echos of the Yellow Peril in the war between the west and the east, including the standard trope of fractious, arguing, and diverse western kingdoms against a unified horde from the east. (To be fair, Eddings does undermine the unity a bit with the Nadraks later in the series, and my recollection is that the Mallorean, a follow-on series, undermines it even further.) Given that, I've been trying to figure out why I had fond memories of this series and enjoyed this re-read, since that normally isn't my thing. There are a few elements that are best talked about in the context of the next book, but one element shows up here as the party of heroes, finishing their forced detour in Cherek, head south through Arendia. Eddings is aware that he's stereotyping each nation of people in this world and embraces it so thoroughly that it stops feeling like stereotypes and starts feeling more like a fable. The Arends are a great example. Arendia is pure medieval fantasy world (even more so than the rest of this world). There are knights in castles, large forests reserved for noble hunting, and miserable serfs. The Arends, apart from the serfs, are full of tales of glory and honor, are impulsive and loyal to a fault, and are in the midst of a simmering internal war that's just barely not broken into open fighting. But the Arends know that they have an unhealthy obsession with honor, know that they constantly get themselves into trouble by being absolutist about honor and far too impulsive, and can't seem to help themselves. They bemoan the war while being apparently unable to do anything that would bring it to an end. If you think of them as people, none of this makes much sense. If you think of them as talking animals in a fable, aware of their natures but still governed by them, it starts to strangely work. When they're isolated from their society by joining the protagonists' party (the early part of this series mostly involves collecting people, for reasons explained later in the series, while following the trail of a thief), the characters of Eddings's world start developing a bit more nuance and depth. But even then, it's more within the bounds that one would expect in a long fable, and falls a bit short of human growth. The lion might learn something from the badger, but the lion is still a lion. With that frame, the first half of this book is rather entertaining. Eddings is taking the stereotype of the noble knight from a typical Arthurian romance and treating it like a class of animal in a fable, which I think is subtly delightful. There's even a doomed love triangle (a very chaste one, which is a reminder that this series was probably targeted at YA readers). The reader joins the primary characters in a sense of bemused exasperation. (Well, Garion takes the doomed love triangle much too seriously, but he's young). Unfortunately, the second half of this book is not one of the finest moments in this series. It's mostly a duet of whining. The first half of the whining comes from Garion, who finally discovers one of the many things about himself that's been obvious to the readers since the middle of the first book, and then promptly develops one of the worst cases of pathetic angst you'll encounter. The people who have been lying to him and keeping secrets from him are now all eager to teach him, which grates almost as much, whereas he's determined to never use his abilities. It makes me think the worst of absolutely everyone involved, and it all happens in one of the most depressing and disgusting settings of the book. The second half of the whining comes from Ce'Nedra, who is by far my least favorite character of this series. She's intended to be an obnoxious, spoiled, imperious brat, and also runs headlong into gender roles in this series, which means she's a living mass of irritation and gender stereotypes, made worse by the fact that the protagonists mostly tolerate her and Garion's reactions to her nonsense are also whiny and obnoxious. It's not my favorite bit of reading. Ce'Nedra does get marginally better later in the series, but she's at her worst here, at the same time Garion is at his worst, which makes the last half of this book a real chore. The only real plus side is that the voice in the back of Garion's head gets a few great moments, but more on that in the next book where it starts playing a prominent role. I should note here that Eddings isn't a complete disaster on gender in this series. There are a lot of unexamined stereotypes, but there are also a lot of examined ones, and it's obvious in places that he's trying. Polgara is a major character, women get some agency in this story, and they at least appear (which is never a given in Tolkien-derivative fantasy). But it's pretty obvious that gender roles start from a "men are from Mars, women are from Venus" set of expectations and then run into Eddings's general tendency to exaggerate all such divisions to fable levels, which in places isn't pretty. And, well, there are all-female giggly dryads who have to capture men to reproduce and who have a euphoric reaction to chocolate. That's a thing that happens. So you may or may not want to agree with me about the completeness of the disaster. Adjust expectations accordingly. If Queen of Sorcery had stuck with the tone of the first half of the book, I would say that it was doing something oddly interesting and showing some of the charm that made me want to re-read this series. Unfortunately, the second half of the book is a bit of a disaster, full of characters acting in ways that makes them very hard to like. Still, I plowed through this book in a couple nights of reading, so there's something here that draws one through the story. And the next book of the series is considerably better. Followed by Magician's Gambit. Rating: 6 out of 10

Philipp Kern: Automating the installation of Debian on z/VM instances

I got tired of manually fetching installation images via either FTP or by manually transferring files to z/VM to test s390x installs. Hence it was about time to automate it. Originally I wanted to instrument an installation via vmcp from another instance on the same host but I figured that I cannot really rely on a secondary instance when I need it and went the s3270/x3270-script way instead.

The resulting script isn't something I'm particularly proud of, especially as it misses error handling that really should be there. But this is not expect instead you operate on whole screens of data and z/VM is not particularly helpful in telling you that you just completed your logon either. Anyway, it seems to work for me. It downloads the most recent stable or daily image if they are not present yet, uploads them via DFT to CMS and makes sure that the installation does not terminate when the script disconnects. Sadly DFT is pretty slow, so I'm stuck with 70 kB/s and about five minutes of waiting until kernel and initrd are finally uploaded. Given that installations themselves are usually blazingly fast on System z, I'm not too annoyed by that, though.

I previously wrote about a parmfile example that sets enough options to bring debian-installer to the point of a working network console via SSH without further prompting. It's a little unfortunate that s390-netdevice needs to be preseeded with the hardware addresses of the network card in all cases, even if only one is available. I should go and fix that. For now this means that the parmfile will be dependent on the actual VM system definition. With that in mind there is an example script in the same gist that writes out a parmfile and then calls the reinstall script mentioned above. Given that debian-installer now supports HTTPS (so far only in the daily images) you can even do a reasonably secure bootstrapping of the network console credentials and preseeding settings.

If you put this pretty generic preseed configuration file onto a securely accessible webserver and reference it from the parmfile, you can also skip the more tedious questions at the beginning of debian-installer. A secure transport is encouraged as preseed files can do anything to your installation process. Unfortunately it seems that there is no way to preseed SSH keys for the resulting installation yet, neither for the created user nor for root. So I haven't achieved my desired target of a fully automated installation just yet. Debian's Jenkins setup just went with insecure defaults, but given that my sponsored VMs are necessarily connected to the public Internet that seemed like a bad idea to me. I suppose one way out would be to IP/password ACL the preseed file. Another one to somehow get SSH key support into user-setup.

Sven Hoexter: Out of the comfort zone: OpenSuSE support for an ordinary user - f*ck my morals

A friend of mine choose for $reasons to install the latest OpenSuSE 42.2 release as his new laptop operating system. It's been a while that I had contact with the SuSE Linux distribution. Must be around 12 years or so. The unsual part here is that I've to support a somewhat eccentric, but mostly ordinary user of computers. And to my surprise it's still hard to just plug in your existing stuff and expect it work. I've done so many dirty things to this installation in the last three days, my system egineering heart is bleeding. printing with a Canon Pixma iP100 printer This is a small portable Canon printer, about four years old. It provides a decent quality and its main strength is that it's small and really portable. Sadly the gutenprint driver just pushes through a blank page. No ink wasted on it at all. So the only reasonable other choice was a four year old binary rpm package provided by Canon. It has a file dependency on "libtiff.so.3" which is no longer available in recent GNU/Linux distributions. So I cheated and
- unpacked the tarball
- installed the rpm from the "packages" folder
zypper install cnijfilter-common-3.70-1.x86_64.rpm cnijfilter-ip100series-3.70-1.x86_64.rpm
... and choose to ignore the missing file dependency on libtiff.so.5.
ln -s /usr/lib64/libtiff.so /usr/lib64/libtiff.so.5
- re-ran the ./install.sh which registered the printer with cups and does whatever else
  magic is included in 1906 lines of shell.
To my surprise this driver still works and provides the expected quality. Though it's just a question of time until this setup will break. Be it an incompatible ABI change in libtiff or another lib in use by those Canon provided tools. QGIS and gdal with ECW support While the printer stuff is a rather common use case, having a map viewer for map files in the ECW format is the eccentric part. I found some hints on stackoverflow and subsequently https://trac.osgeo.org/gdal/wiki/ECW that a non-free library is required and a specific build of gdal. Then QGIS should be able to work with ECW files. Lucky us there is at least a OpenSuSE repository for gdal and QGIS. So I did the following:
zypper addrepo http://download.opensuse.org/repositories/Application:/Geo/openSUSE_Leap_42.2/Application:Geo.repo
zypper install qgis
Then I had to download the non-free ECW SDK from http://download.hexagongeospatial.com/downloads/erdas-ecw-jp2-sdk-v5.3-%28linux%29 - you'll and up with a '.bin' installer file. The installation process left me with "ERDAS-ECW_JPEG_2000_SDK-5.3.0" folder in my $HOME. I moved that one to /opt. Next step is adding the library to the ldconfig search path.
echo "/opt/ERDAS-ECW_JPEG_2000_SDK-5.3.0/Desktop_Read-Only/lib/x64/release/" > /etc/ld.so.conf.d/ecw.conf; ldconfig
Now it was "just" about rebuild gdal with ECW support. So I downloaded the required source packages with "zypper source-install gdal", edited the spec somewhere in "/usr/src/" to make the following modifications
--with-ecw=/opt/ERDAS-ECW_JPEG_2000_SDK-5.3.0/Desktop_Read-Only
added to the "./configure" invocation. And somewhere at the top we had to relax the requirement that all installed files have to be referenced inside the package.
%define _unpackaged_files_terminate_build 0
As a last step I had to "rpmbuild -ba" the package and force the installation via zypper once more, because this time we have a file depedency on the libecw stuff and it's obviously not listed in the rpm database. Last but not least I tried to put the gdal build on hold with
zypper addlock gdal libgdal20
to ensure it's not removed on the next update. Other non-free tools Beside of those two issues I had to install a range of other non-free tools, but currently they work without further issues or modifications. One is Teamviewer (i686 multiarch rpm) and the other one is XnViewMP. XnView is also able to show ECW files, but only the smaller ones. It crashes on bigger ones but that's also the case on Windows. Then there is also (required by some Italian map related websites) the ugly Adobe Flash Plugin for Firefox, but that one is sadly still a widespread issue. We also tried to try out the nvidia graphic drivers but at the moment we could only get the build in Intel card to work. Usually the preferred solution from my point of view but sometimes we see rendering glitches and I'm not sure if it's the driver or something else. my personal take away I hate to admit it but it's nothing extraordinary that was requested here. But still it took me the better part of two evenings to figure everything out. And even now it's not properly integrated and doomed to fail any day due to various updates and changes in the surounding ecosystem. I've full sympathy for every average user that would give up after two hours of research and try&error on this journey. For the printer drivers I'm happy to blame Canon. The printer situation as a whole improved from my point of view during the last decade, but it's still a pain in the ass with the very short shelf life you usually see with consumer models. For the ECW case one could discuss if it would be legally possible and helpful to do ugly dlopen() stuff to dynamcially load the shared libs. But then again someone has to make his hands dirty during the build and discussions about the legal use of header files will be the next chapter (hello Oracle). It's just ugly. Actually I know too little about the world of image formats to judge if someone has a good reason to keep this format commercial or not. From my personal point of view it's not useful and maybe even morally wrong. Technically one could argue if it would make sense to keep a local copy of the gdal build in "/opt" and start QGIS with a modified library path to prefer the private gdal build. Not sure if that is any better. On the other hand there are evolving mechanism like flatpack that would ease the handling of such situations. Buth then again we would be catering non-free software. It feels a lot like giving up. While my private working environment is except for firmware blobs free, I now created for someone a real "FrankenSuSE" to satisfy his everyday needs. On the one hand we now have another mostly satisfied user of a mostly free operating system. On the other hand that was only possible by adding a vast amount of non-free software. For sure we did not win the war, I'm not even sure if we've won a single battle here. It's just frustrating to see what is required to get someone up and running. With my personal attitude towards open source software it even feels wrong to invest so much time into fiddling with non-free components. What is still missing We currently lack an image viewer that allows us to print only a selection of an image, which is useful to print parts of a map. That usually works with XnView on Windows but does not work with the Linux version at the moment. I also tried gwenview and geeqie and had the same issue. Not sure if it's maybe a bug in XnView or one of the Qt parts (gwenview is also Qt based). I did not research that yet. Update: I spent quite some time looking into open bug reports for geeqie and gwenview. Seems the feature to print only a section of an image is something new. I've created #374299 (gwenview) and #457 (geeqie). For XnView I expect it's a difference between XnViewMP (the portable version) and the Windows only XnView Classic. Needs to be clarified and it might be worth to try XnView Classic with wine. Maybe printing with wine via cups works, I found at least some results for it on the internet.

What happened in the Reproducible Builds effort between Sunday December 18 and Saturday December 24 2016: Media coverage 100% Of The 289 Coreboot Images Are Now Built Reproducibly by Phoronix, with more details in German by Pro-Linux.de. We have further reports on our Reproducible Builds World summit #2 in Berlin from Rok Garbas of NixOS as well as Clemens Lang of MacPorts Debian infrastructure work Dak now archives buildinfo files thanks to a patch from Chris Lamb. We also have mostly finalised a design of how they will be distributed by the Debian FTP mirror network which we will start implementing soon. This is great for the future of Debianb but unfortunately this also means that we won't have .buildinfo files for Stretch as Debian will not rebuild its source packages and because these binary packages currently in the archive were mostly built with dpkg > 1.18.11. reprepro/5.0.0-1 has added support for dealing with .buildinfo files that are included in .changes files. (Closes: #843402) Reproducible work in other projects The Chromium project is now working on making their build process (mostly) deterministic.

Russ Allbery: Review: Pawn of Prophecy

Review: Pawn of Prophecy, by David Eddings
Series: The Belgariad #1
Publisher: Del Rey
Copyright: April 1982
Printing: August 1990
ISBN: 0-345-33551-1
Format: Mass market
Pages: 258
I hit a period in November when I felt like reading something entirely undemanding and fun, something that was predictable, comfortable, and guaranteed to be a happy ending. There are times in life for books like that. I've been vaguely thinking of re-reading the Belgariad for a while, which I'd not read since I was in college, and that seemed to fit the bill. Garion is a farm-boy in Sendaria, a quiet and industrious kingdom full of farmers. His only family is his Aunt Pol, who ran the kitchen at Faldor's farm. His life has all the hallmarks of being entirely unremarkable, despite occasional visits by a traveling vagabond, Wolf, who clearly knows his Aunt Pol. But then something extremely important is stolen elsewhere, Wolf and Pol have to leave to pursue it for reasons that are quite murky to Garion, and Pol is unwilling to leave Garion behind. This begins Garion's great adventure, in which he becomes far more important and powerful than he would have ever imagined. That's the promise, at least, and the stock plot of every series like this. And let me be clear up front: the Belgariad is very stock. That's part of what I was in the mood for, but don't come to this series looking for interesting differentiation. It's clearly in the center of the secondary world chosen one fantasy genre, with a great evil, forces of good arrayed against it, and someone who unknowingly has the power to stop evil but has to learn how to use it. If you're in the mood for this, every note will be comfortably familiar; if not, it might be boringly predictable. Unfortunately, this particular book does not cast the Belgariad in a good light. Garion's introduction to this story is intensely irritating, almost entirely because no one will tell him what's going on. Pol is excessively protective (smotheringly so), but shuts down any questions he has and doesn't explain why she's freaking out. (This doesn't become entirely clear until towards the end of the second book.) What little scraps Garion picks up, he has to get by eavesdropping. Even by the end of this book, when Garion has met royalty and started helping with larger political issues (albeit mostly by accident), everyone is keeping him in the dark and he doesn't believe the hints he's gotten. I can't remember how I reacted to this the first time I read this series, but the second time through, it was extremely frustrating. The frustration is stronger because any regular reader of this genre knows exactly what Garion is, although not precisely how the story will play out, and can make fairly good guesses about Pol and Wolf from early in the story. Everyone playing coy doesn't even add legitimate suspense or set up a big reveal. It just made me irritated at Garion's blindness (it's mildly understandable given how foreign the idea is to his life, but he seems remarkably dense even with that), and even more irritated at Wolf and, in particular, Aunt Pol for keeping him so thoroughly in the dark. Garion is very attached to his aunt; on this re-reading, I wasn't entirely sure why. She occasionally shows love and support, and she's certainly wise, but for most of the book she treats him with brusque condescension and tries to keep him as ignorant as possible. Garion's weird entanglement with a black rider that he'd seen for most of his life doesn't make this any better. It's creepy and disturbing, it's not entirely resolved in this book, and Garion is clearly in danger, which wasn't the vibe that I was looking for when starting this re-read. And it's hard to escape the feeling that Garion might have managed to tell someone if all the adult figures in his life weren't so secretive, dismissive, and excessively controlling. So, all in all, an inauspicious beginning. It was good enough to keep me reading when I first read the series, and it was good enough on this re-read, but just barely. The saving grace is Silk and Barak, when the story finally meets them. Those who have read this series will know that they're just the beginning of the party-building process that will take up much of this series (so many Lord of the Rings resonances), but the one thing I will give Eddings is that he writes entertaining supporting characters. Both of them are a bit stereotyped, but they add so much to this story. Silk in particular is a delight and remains a delight throughout the series, adding a much-needed level of snark and sneaky enjoyment that lightens so many of the serious episodes of this story. The Belgariad in general is highly derivative map exploration fantasy, and you shouldn't expect anything deeper. It is, however, enjoyable map exploration fantasy with some entertaining supporting cast members. Sadly, only the glimmers of that are visible from this book. Pawn of Prophecy is mostly an irritating tour of bad parenting techniques, refusal to talk to teenagers, sneaking around to get information that should have been legitimately shared, and taking forever to get around to the mythology that we all know is coming. I therefore can't recommend this book, although one does have to read it in order to read the rest of the series, which as I recall gets considerably better. Followed by Queen of Sorcery.

Francois Marier: Using iptables with NetworkManager

I used to rely on ifupdown to bring up my iptables firewall automatically using a config like this in /etc/network/interfaces:
allow-hotplug eth0
iface eth0 inet dhcp
    pre-up /sbin/iptables-restore /etc/network/iptables.up.rules
    pre-up /sbin/ip6tables-restore /etc/network/ip6tables.up.rules
allow-hotplug wlan0
iface wlan0 inet dhcp
    pre-up /sbin/iptables-restore /etc/network/iptables.up.rules
    pre-up /sbin/ip6tables-restore /etc/network/ip6tables.up.rules
but that doesn't seem to work very well in the brave new NetworkManager world. What does work reliably is a "pre-up" NetworkManager script, something that gets run before a network interface is brought up. However, despite what the documentation says, a dispatcher script in /etc/NetworkManager/dispatched.d/ won't work on my Debian and Ubuntu machines. Instead, I had to create a new iptables script in /etc/NetworkManager/dispatcher.d/pre-up.d/:
#!/bin/sh
LOGFILE=/var/log/iptables.log
if [ "$1" = lo ]; then
    echo "$0: ignoring $1 for \ $2'" >> $LOGFILE
    exit 0
fi
case "$2" in
    pre-up)
        echo "$0: restoring iptables rules for $1" >> $LOGFILE
        /sbin/iptables-restore /etc/network/iptables.up.rules >> $LOGFILE 2>&1
        /sbin/ip6tables-restore /etc/network/ip6tables.up.rules >> $LOGFILE 2>&1
        ;;
    *)
        echo "$0: nothing to do with $1 for \ $2'" >> $LOGFILE
        ;;
esac
exit 0
and then make that script executable:
chmod a+x /etc/NetworkManager/dispatcher.d/pre-up.d/iptables
With this in place, I can put my iptables rules in the usual place (/etc/network/iptables.up.rules and /etc/network/ip6tables.up.rules) and use the handy iptables-apply and ip6tables-apply commands to test any changes to my firewall rules.

Lucas Nussbaum: The Linux 2.5, Ruby 1.9 and Python 3 release management anti-pattern

There s a pattern that comes up from time to time in the release management of free software projects. To allow for big, disruptive changes, a new development branch is created. Most of the developers focus moves to the development branch. However at the same time, the users focus stays on the stable branch. As a result: This situation can grow up to a quasi-deadlock, with people questioning whether it was a good idea to do such a massive fork in the first place, and if it is a good idea to even spend time switching to the new branch. To make things more unclear, the development branch is often declared stable by its developers, before most of the libraries or applications have been ported to it. This has happened at least three times. First, in the Linux 2.4 / 2.5 era. Wikipedia describes the situation like this:

Before the 2.6 series, there was a stable branch (2.4) where only relatively minor and safe changes were merged, and an unstable branch (2.5), where bigger changes and cleanups were allowed. Both of these branches had been maintained by the same set of people, led by Torvalds. This meant that users would always have a well-tested 2.4 version with the latest security and bug fixes to use, though they would have to wait for the features which went into the 2.5 branch. The downside of this was that the stable kernel ended up so far behind that it no longer supported recent hardware and lacked needed features. In the late 2.5 kernel series, some maintainers elected to try backporting of their changes to the stable kernel series, which resulted in bugs being introduced into the 2.4 kernel series. The 2.5 branch was then eventually declared stable and renamed to 2.6. But instead of opening an unstable 2.7 branch, the kernel developers decided to continue putting major changes into the 2.6 branch, which would then be released at a pace faster than 2.4.x but slower than 2.5.x. This had the desirable effect of making new features more quickly available and getting more testing of the new code, which was added in smaller batches and easier to test. Then, in the Ruby community. In 2007, Ruby 1.8.6 was the stable version of Ruby. Ruby 1.9.0 was released on 2007-12-26, without being declared stable, as a snapshot from Ruby s trunk branch, and most of the development s attention moved to 1.9.x. On 2009-01-31, Ruby 1.9.1 was the first release of the 1.9 branch to be declared stable. But at the same time, the disruptive changes introduced in Ruby 1.9 made users stay with Ruby 1.8, as many libraries (gems) remained incompatible with Ruby 1.9.x. Debian provided packages for both branches of Ruby in Squeeze (2011) but only changed the default to 1.9 in 2012 (in a stable release with Wheezy 2013). Finally, in the Python community. Similarly to what happened with Ruby 1.9, Python 3.0 was released in December 2008. Releases from the 3.x branch have been shipped in Debian Squeeze (3.1), Wheezy (3.2), Jessie (3.4). But the python command still points to 2.7 (I don t think that there are plans to make it point to 3.x, making python 3.x essentially a different language), and there are talks about really getting rid of Python 2.7 in Buster (Stretch+1, Jessie+2). In retrospect, and looking at what those projects have been doing in recent years, it is probably a better idea to break early, break often, and fix a constant stream of breakages, on a regular basis, even if that means temporarily exposing breakage to users, and spending more time seeking strategies to limit the damage caused by introducing breakage. What also changed since the time those branches were introduced is the increased popularity of automated testing and continuous integration, which makes it easier to measure breakage caused by disruptive changes. Distributions are in a good position to help here, by being able to provide early feedback to upstream projects about potentially disruptive changes. And distributions also have good motivations to help here, because it is usually not a great solution to ship two incompatible branches of the same project. (I wonder if there are other occurrences of the same pattern?) Update: There s a discussion about this post on HN

Steinar H. Gunderson: Cracking a DataEase password

I recently needed to get access to a DataEase database; the person I helped was the legitimate owner of the data, but had forgotten the password, as the database was largely from 1996. There are various companies around the world that seem to do this, or something similar (like give you an API), for a usually unspecified fee; they all have very 90s homepages and in general seem like they have gone out of business a long time ago. And I wasn't prepared to wait. For those of you who don't know DataEase, it's a sort-of relational database for DOS that had its heyday in the late 80s and early 90s (being sort of the cheap cousin of dBase); this is before SQL gained traction as the standard query language, before real multiuser database access, and before variable-width field storage. It is also before reasonable encryption. Let's see what we can do. DataEase has a system where tables are mapped through the data dictionary, which is a table on its own. (Sidenote: MySQL pre-8.0 still does not have this.) This is the file RDRRTAAA.DBM; I don't really know what RDRR stands for, but T is the database letter in case you wanted more than one database in the same directory, and AAA, AAB, AAC etc. is a counter so that a table grows to be too big for one file. (There's also .DBA files for structure of non-system tables, and then some extra stuff for indexes.) DBM files are pretty much the classical, fixed-length 80s-style database files; each row has some flags (I believe these are for e.g. row is deleted ) and then just the rows in fixed format right after each other. For instance, here's one I created as part of testing (just the first few lines of the hexdump are shown):
00000000: 0e 00 01 74 65 73 74 62 61 73 65 00 00 00 00 00  ...testbase.....

00000070: 52 65 6c 61 74 69 6f 6e 73 68 69 70 73 00 00 00  Relationships...
Even without going in-depth, we can see the structure here; there's testbase which maps to C:RDRRTAA.DBM (the RDRR itself), there's a table called REPORT DIRECTORY that maps to C:REPOTAAA.DBM, and then more stuff after that, and so on. However, other tables are not so easily read, because you can ask DataEase to encrypt a table. Let's look at such an encrypted table, like the Users table (containing usernames, passwords not password hashes and some extra information like access level), which is always encrypted:
00000000: 0c 01 9f ed 94 f7 ed 34 ba 88 9f 78 21 92 7b 34  .......4...x!. 4
00000010: ba 88 0f d9 94 05 1e 34 ba 88 a0 78 21 92 7b 34  .......4...x!. 4
00000020: e2 88 9f 78 21 92 7b 34 ba 88 9f 78 21 92 7b 34  ...x!. 4...x!. 4
00000030: ba 88 9f 78 21 92 7b 34 ba 88 9f 78 21 92 7b     ...x!. 4...x!. 
Clearly, this isn't very good encryption; it uses a very short, repetitive key of eight bytes (64 bits). (The data is mostly zero padding, which makes it much easier to spot this.) In fact, in actual data tables, only five of these bytes are set to a non-zero value, which means we have a 40-bit key; export controls? My first assumption here was of course XOR, but through some experimentation, it turned out what you need is actually 8-bit subtraction (with wraparound). The key used is derived from both a database key and a per-table key, both stored in the RDRR; again, if you disassemble, I'm sure you can find the key derivation function, but that's annoying, too. Note, by the way, that this precludes making an attack by just copying tables between databases, since the database key is different. So let's do a plaintext attack. If you assume the plaintext of the bottom row is all padding, that's your key and here's what you end up with:
00000000: 52 79 00 75 73 65 72 00 00 00 00 00 00 00 00 00  Ry.user.........
00000010: 00 00 70 61 73 73 a3 00 00 00 01 00 00 00 00 00  ..pass..........
00000020: 28 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  (...............
00000030: 00 00 00 00 00 00 00 00                          ........ 
Not bad, eh? Actually the first byte of the key here is wrong as far as I know, but it didn't interfere with the fields, so we have what we need to log in. (At that point, we've won, because DataEase will helpfully decrypt everything transparent for us.) However, there's a twist; if the password is longer than four characters, the entire decryption of the Users table changes. Of course, we could run our plaintext attack against every data table and pick out the information by decoding the structure, but again; annoying. So let's see what it looks like if we choose passs instead:
00000000: 0e 01 9f 7a ae 9e 21 f5 08 63 07 6d a3 a1 17 5d  ...z..!..c.m...]
00000010: 70 cb df 36 7e 7c 91 c5 d8 33 d8 3d 73 71 e7 2d  p..6~ ...3.=sq.-
00000020: 7b 9b 3f a5 db d9 4f 95 a8 03 a7 0d 43 41 b7 fd   .?...O.....CA..
00000030: 10 6b 0f 75 ab a9 1f 65 78 d3 77 dd 13 11 87     .k.u...ex.w....
Distinctly more confusing. At this point, of course, we know at which byte positions the username and password start, so if we wanted to, we could just try setting the start byte of the password to every possible byte in turn until we hit 0x00 (DataEase truncates fields at the first zero byte), which would allow us to get in with an empty password. However, I didn't know the username either, and trying two bytes would mean 65536 tries, and I wasn't up for automating macros through DOSBox. So an active attack wasn't too tempting. However, we can look at the last hex byte (where we know the plaintext is 0); it goes 0x5d, 0x2d, 0xfd... and some other bytes go 0x08, 0xd8, 0xa8, 0x78, and so on. So clearly there's an obfuscation here where we have a per-line offset that decreases with 0x30 per line. (Actually, the increase/decrease per line seems to be derived from the key somehow, too.) If we remove that, we end up with:
00000000: 0e 01 9f 7a ae 9e 21 f5 08 63 07 6d a3 a1 17 5d  ...z..!..c.m...]
00000010: a0 fb 0f 66 ae ac c1 f5 08 63 08 6d a3 a1 17 5d  ...f.....c.m...]
00000020: db fb 9f 05 3b 39 af f5 08 63 07 6d a3 a1 17 5d  ....;9...c.m...]
00000030: a0 fb 9f 05 3b 39 af f5 08 63 07 6d a3 a1 17     ....;9...c.m...
Well, OK, this wasn't much more complicated; our fixed key is now 16 bytes long instead of 8 bytes long, but apart from that, we can do exactly the same plaintext attack. (Also, it seems to change per-record now, but we don't see it here, since we've only added one user.) Again, assume the last line is supposed to be all 0x00 and thus use that as a key (plus the last byte from the previous line), and we get:
00000000: 6e 06 00 75 73 65 72 00 00 00 00 00 00 00 00 00  n..user.........
00000010: 00 00 70 61 73 73 12 00 00 00 01 00 00 00 00 00  ..pass..........
00000020: 3b 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ;...............
00000030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00     ...............
Well, OK, it wasn't perfect; we got pass\x12 instead of passs , so we messed up somehow. I don't know exactly why the fifth character gets messed up like this; actually, it cost me half an hour of trying because the password looked very real but the database wouldn't let me in, but eventually, we just guessed at what the missing letter was supposed to be. So there you have it; practical small-scale cryptanalysis of DOS-era homegrown encryption. Nothing advanced, but the user was happy about getting the data back after a few hours of work. :-)

Jonathan McDowell: The terrible PIC ecosystem

I recently had call to play with some 1-Wire devices at work (more of which in a future post). It was taking a while for the appropriate programmer to turn up, so of course I pulled out my trusty BusPirate. It turned out the devices in question would only talk in overdrive mode, while the Bus Pirate could only offer standard mode. So I set about trying to figure out how to add the appropriate support. This is is a huge endorsement for test equipment with Free Software firmware. Rather than giving up I was able to go and grab the current firmware, which has been adopted by the community since Dangerous Prototypes have discontinued development. What let me down was the ecosystem around the PIC24FJ64GA002. My previous recent experience with microcontrollers has been with the ATTiny range and the STM32. Getting up and running with both of these was fairly easy - the tool chains necessary were already present in Debian, so all it took was a simple apt invocation to install everything I needed to compile code and program it to the devices. Not so with the PIC series, which surprised me. There seems to be some basic support for the earlier PIC16 range, but for later chips there s nothing that works out of the box with Debian. Investigation revealed that this was because there s nothing maintained that enabled Free development for the PIC range. The accepted solution is the closed MPLAB X. Now, in one sense fair play to Microchip for making this available. But in another, shame on you. I can t imagine ever choosing to build something based on a chip that only had a closed source tool chain available. I want things I can use in Makefiles and properly script, that are available in my distro of choice and that generally work in the same fashion as the tool chains I m used to. I understand there might be some benefit in a closed compiler in terms of performance (and have HPC friends who would never trust a benchmark provided using GCC), but in general that s not the space I move in. Nor does it seem to be the sort of attitude you should be taking if you are trying to attract the hobbyist and small production run market. Any yet this seems common amongst hardware manufacturers. People whose core business is selling physical items, where the software is only relevant in terms of being able to use those items, seem to consider the software to be precious. Instead of opening up programming specifications and allowing a more widespread use of the hardware, increasing sales. I understand there are some cases where this isn t practical, but the default attitude is definitely one of being closed rather than open, which is a terrible shame. Anyway. I do have some Bus Pirate 1-Wire overdrive support now working (pending some testing to ensure standard mode still works), but I am glad I never spent a lot of time getting involved with PICs now.

Shirish Agarwal: My letter to Government of Maharashtra on Real Estate Rules and Regulation Draft rules

While I try to minimize Politics and Economics as much as I can on this blog, it sometimes surfaces. It is possible that some people may benefit or at least be aware. A bit of background is necessary before I jump into the intricacies of the Maharashtra Real Estate Rules and Regulation Draft Rules 2016 (RERA) . Since ever, but more prominently since 2007/8 potential homeowners from across the country have been suffering at the hands of the builder/promoter for number of years. While it would be wrong to paint all the Real Estate Developers and Builders as cheats (we as in all tenants and homeowners hope there are good ones out there) many Real Estate Builders and promoters have cheated homeowners of their hard-earned money. This has also lessened the secondary (resale) market and tenants like me have to fight over morsels as supply is tight. There were two broad ways in which the cheating is/was done a. Take deposits and run away i.e. fly by night operators Here the only option for a homeowner is to file an FIR (First Information Report) and hope the culprits are caught. 99% of the time the builder/promoter goes somewhere abroad and the potential home buyers/home-owners are left holding the can. This is usually done by small real estate promoters and builders. b. The big boys would take all or most money of the project, may register or not register the flat in your name, either build a quarter or half-finished building and then make excuses. There are some who do not even build. The money given is used by the builder/developer either for his own needs or using that money in some high-profile project which is expensive and may have huge returns. They know that home-owners can t do anything, at the most go to the court which will take more than a decade or two during which time the developer would have interest-free income and do whatever he wants to do. One of the bigger stories which came up this year was when the Indian Cricket Captain, M.S. Dhoni (cricket is a religion in India, and the cricketers gods for millions of Indians) had to end his brand engagement and ambassadorship from Amrapali Housing Group. Apparently, his wife Sakshi was on the Board of directors at Amrapali Housing and had to resign The Government knew of such issues and had been working since last few years. Under the present Government, a Model Agreement and a Model Real Estate Rules and Regulation Bill was passed on 31st March and came into force on 1st May 2016. India, similar to the U.S. and U.K. follows a federal structure. While I have shared this before, most of the laws in India fall in either of three lists, Central List, Concurrent Lists and State Lists. Housing for instance, is a state subject so any laws concerning housing has to be made by the state legislature. Having a statutory requirement to put the bill in 6 months from 1st of May, the Government of Maharashtra chose to put the draft rules in public domain on 12th December 2016, about 10 days ago and there were efforts to let it remain low-key so people do not object as we are still in the throes of demonetisation. By law they should have given 30 days for people to raise objections and give suggestions. The State Government too could have easily asked an extension and as both the State and the Centre are of the same Political Party they would have easily got it. With that, below is the e-mail I sent to suggesstionsonrera@maharashtra.gov.in Sub Some suggestions for RERA biggest suggestion, need to give more time study the implications for house-owners. Respected Sir/Madame, I will be publishing the below mail as a public letter on my blog as well. I am writing as a citizen, a voter, a potential home owner, currently a tenant . If houses supply is not in time, it is us, the tenants who have the most to lose as we have to fight over whatever is in the market. I do also hope to be a home buyer at some point in time so these rules would affect me also somewhere in the hazy future. I came to know through the media that Maharashtra Govt. recently introduced draft rules for RERA Real Estate (Regulation and Development) Act, 2016 . I hope to impress upon you that these proposed Rules and Regulations need to be thoroughly revised and new draft rules shared with the public at large with proper announcement in all newspapers and proper time ( more than a month ) to study and give replies on the said matter. My suggestions and complaints are as under a. The first complaint and suggestion is that the date between the draft regulations and suggestions being invited by members of public is and was too little 12 December 2016 23 December 2016 (only 11 days) for almost 90 pages of Government rules and regulations which needs multiple rounds of re-reading to understand the implications of the draft rules . Add to that unlike the Central Building Legislation, Model Agreement which was prepared by Centre and also given wide publicity, the Maharashtra Govt. didn t do any such publicity to bring it to the
notice of the people. b. I ask where was the hurry to publish these draft rules now when everybody is suffering through the result of cash-crunch on top of other things. If the said draft rules were put up in January 2017, I am sure more people would have responded to the draft rules. Ir raises suspicion in the mind of everybody the timing of sharing the draft rules and the limited time given to people to respond. E.g. When TRAI (Telephone Regulatory Authority of India) asked for suggestion it gives more than a month, and something like housing which is an existential question for everybody, i.e. the poor, the middle and the rich, you have given pretty less time. While I could change my telephone service providers at a moment s notice without huge loss, the same cannot be said either for a house owner (in case of builder) or a tenant as well. This is just not done. c. The documents are at https://housing.maharashtra.gov.in/sitemap/housing/Rera_rules.htm under different sub-headings while the correct structure of the documents can be found at nared s site
http://naredco.in/notifications.asp . At the very least, the documents should have been in proper order. Coming to some of the salient points raised both in the media and elsewhere 1. On page 6 of Part IV-A Ext1.pdf you have written Explanation.-The registration of a real estate project shall not be required,- (i) for the purpose of any renovations or repair or redevelopment which does not involve marketing, advertisement, selling or new allotment of any apartment , plot or building as the case may be under
the real estate project; RERA draft rules What it means is that the house owner and by the same stroke the tenant would have absolutely no voice to oppose any changes made to the structure at any point of time after the building is built. This means the builder is free to build 12-14-16 even 20 stories building when the original plans were for 6-8-10. This rule gives the builder to do free for all till the building doesn t get converted into a society, a process which does and can take years to happen. 2. A builder has to take innumerable permissions from different authorities at each and every stage till possession of a said property isn t handed over to a home buyer and by its extension to the tenant. Now any one of these authorities could sit on the papers and there is no accountability of by when papers would be passed under a competent authority s desk. There was a wide belief that there would be some
rules and regulations framed in this regard but the draft rules are silent on the subject matter. 3. In Draft rule 5. page 8 of Part IV-A Ext1.pdf you write Withdrawal of amounts deposited in separate account.-(1) With regard to the withdrawal of amounts deposited under sub-clause (D) of clause (l) of sub-section (2) of section 4, the following provisions shall apply:- (i) For new projects which will be registered after commencement. Deposit in the escrow account is from now onwards. So what happens to the projects which are ongoing at the moment, either at the registration stage or at building stage, thousands of potential house owners would be left to fend for themselves. There needs to be some recourse for them as well. 3b. Another suggestion is that the house-owners are duly informed when promoters/builders are taking money from the bank and should have the authority to see that proper documents and procedure was followed. It is possible that unscrupulous elements may either bypass it or give some different documents which are not in knowledge of the house-owner, thus defeating the purpose of the escrow account itself. 4. On page 44 of Pt.IV-A Ext.161 in the Model Agreement to be entered
between the Promoter and the Alottee you have mentioned (i)The Allottee hereby agrees to purchase from the Promoter and the Promoter hereby agrees to sell to the Allottee one Apartment No. .. of the type .. of carpet area admeasuring .. sq. metres on floor in the building __________along with (hereinafter referred to as the Apartment ) as shown in the Floor plan thereof hereto annexed and marked Annexures C
for the consideration of Rs. . including Rs. . being the proportionate price of the common areas and facilities appurtenant to the premises, the nature, extent and description of the common/limited common areas and facilities which are more particularly described in the Second Schedule annexed herewith. (the price of the Apartment including the proportionate price of the limited common areas and facilities and parking spaces should be shown separately). (ii) The Allottee hereby agrees to purchase from the Promoter and the Promoter hereby agrees to sell to the Allottee garage bearing Nos ____ situated at _______ Basement and/or stilt and /or ____podium being
constructed in the layout for the consideration of Rs. ____________/- (iii) The Allottee hereby agrees to purchase from the Promoter and the Promoter hereby agrees to sell to the Allottee Car parking spaces bearing Nos ____ situated at _______ Basement and/or stilt and /or ____podium and/or open parking space, being constructed in the layout for the
consideration of Rs. ____________/-. The total aggregate consideration amount for the apartment including garages/car parking spaces is
thus Rs.______/- Draft rules. What has been done here is the parking space has been divorced from sale of the flat . It is against natural justice, logic, common sense as well-known precedents in jurisprudence (i.e. law) In September 2010, the bench of Justices R M Lodha and A K Patnaik had ruled in a judgement stating developers cannot sell parking spaces as independent real-estate units. The court ruled that parking areas are common areas and facilities . This was on behalf of a precedent in Mumbai High Court as well. http://www.reinventingparking.org/2010/09/important-parking-ruling-by-indias.html This has been reiterated again and again in courts as well as consumer
forums http://timesofindia.indiatimes.com/city/mumbai/Cant-charge-flat-buyer-extra-for-parking-slot/articleshow/22475233.cms and has been the norm in several Apartment Acts over multiple states http://apartmentadda.com/blog/2015/02/19/rules-pertaining-to-parking-spaces-in-apartment-complexes/ 5. In case of dispute, the case will high court which is inundated by huge number of pending cases. As recently as August 2016 there was a news item in Indian Express which talks about the spike in pending cases. Putting a case in the high court will weigh heavily on the homeowner, financially and
mentally http://indianexpress.com/article/cities/mumbai/more-cases-and-increased-staff-strength-putting-pressure-on-bombay-high-court-building-2964796/ It may be better to use the services of National Consumer Disputes Redressal Commission'(NCDRC) where there is possibility of quicker justice and quick resolution. There is possibility of group actions taking place which will reduce duplicity of work on behalf of the petitioners. 6. There is neither any clarity, incentive or punitive action against the promoter/builder if s/he delay conveyance to the society in order to get any future developmental and FSI rights. To delay handing over conveyance, the builders delay completion of the last building in a said project. there should be both a compensatory and punitive actions taken against the builder if he is unable to prove any genuine cause for the same. 7. There needs to be the provision with regard to need for developers to make public disclosures pertaining to building approvals. This while I had shared above needs to be explicitly mentioned so house-owners know the promoter/builder are on the right path. 8. There needs to be a provision that prohibits refusal to sell property to any person on the basis of his/her religion, marital status or dietary preferences. 9. There is lot of ambiguity if criminal proceedings can be initiated against a promoter/developer if s/he fails to deliver the flat on time. The developer should be criminally liable if he doesn t give the flat with all the amenities, fixtures and anything which was on agreement signed by both parties and for which the payment has been given in
full at time of possession of a flat. 10. Penalties for the promoter/builder is capped at 10% in case of any wrong-doing. Apart from proving the charge, the onus of which would lie on the house-owner, capping it at 10% is similar to A teacher telling a naughty student, do whatever you want to do, I am only going to hit you 5 times. Such a drafting encourages the Promoter/builder to play mischief. The builder knows his exposure is pretty limited. Liability is limited so he will try to get with whatever he can. Having a high penalty clause will deter him. 11. There was talk and shown in the Center s model agreement the precedent of providing names, addresses and contact details of other allot-tees or home-owners of a building that would have multiple dwelling units . This is nowhere either in the agreement or mentioned anywhere else in the four documents. 12. An addition to the above would be that the details provided should be correct and updated as per the records maintained by the Promoter/builder. 13. Today, there is no way for a potential house-owner to know if the builder had broken any norms or has any cases in court pending against him. There should be a way for the potential house-owner to find out. 14. A builder can terminate a flat purchase agreement by giving just a week s notice on email to the buyer who defaults on an instalment. But the developer can refund the money without interest to the
purchaser at leisure, within six months.Under MOFA (the earlier rules), the developer could cancel the agreement after giving a 15 days notice, and the builder could resell the flat only after refunding money to the original buyer. Under the new draft rules, a builder can immediately sell the flat after terminating the agreement. 15. The new draft rules say a buyer must pay 30% of the total cost while signing the agreement and 45% when the plinth of the building is constructed. The earlier state law stipulated 20% payment when the
agreement is signed with the developer. 16. The Central model agreement and rules proposed a fee of INR Rs 1,000 for filing complaints before housing authority; the state draft has proposed to hike this fee to Rs INR Rs. 10,000/- 17. Reading the Central Model Agreement, key disclosures under Section 4 (2)and Rule 3 (2) of the Central Model Rules have been excluded to be put up on the website of the Authority. These included carpet area of flat, encumbrance certificate (this would have disclosed encumbrances in respect of the land where the real estate project is proposed to be undertaken), copy of the legal title report and sanctioned plan of the building. Due to this house-owner would always be in dark and assume that everything is alright.

The Central rule requires a builder to submit an annual report including profit and loss account, balance sheet, cash flow statement, directors report and auditors report for the preceding three financial years, among other things. However, the Maharashtra draft rules are silent on such a requirement. While the above is what I could perceive in the limited amount I came to know. This should be enough to convince that more needs to be done from the house-owner s side. Update Just saw Quint s Op-Ed goes in more detail.

Shirish Agarwal: The wine and dine at debconf16

For the wine connoisseur

All photos courtesy KK . If any deviations, would put up labels sharing whose copyright it is. Before I get into all of that, I was curious about Canada and taking the opportunity of debconf happening there in a few months, asked few people what they thought of digital payments, fees and expenses in their country and if plastic cash is indeed used therein. The first to answer was Tyler McDonald (no idea if he is anyway related to the fast-food chain McDonalds which is a worldwide operation.) This is what he had to say/share
You can use credit / debit cards almost everywhere. Restaurant waiters also usually have wireless credit / debit terminals that they will bring to your table for you to settle your bill. How much your bank charges depends on your Canadian bank and the banking plan you are on. For instance, on my plan through the Bank Of Montreal, I get (I think) 20 free transactions a month and then after that I m charged $0.50CDN/piece. However, if I go to a Bank Of Montreal ATM and withdraw cash, there is no service fee for that. There is no service fee for using *credit* cards, only *debit* cards tend to have the fee. I live in a really rural area so I can t always get to a Bank Of Montreal machine for cash. So what I usually end up doing, is either pay by credit and then pay of the balance right away so I don t have to pay interest, or when I do use my bank card to pay for something, I ask if I can get cash back as well. Yes, Canada converted to plastic notes a few years ago. We ve also eliminated the penny. For cashless transactions, you pay the exact amount billed. If you re paying somebody in cash, it is rounded up or down to the nearest 5 cents. And for $1 or $2, instead of notes, we ve moved over to coins. I personally like the plastic notes. They re smoother and feel more durable than the paper notes. I ve had one go through a laundry load by accident and it came out the other side fine.
Another gentleman responded with slightly more information which probably would interest travellers from around the world, not just Indians
Quebec has its own interbank system called Interac (https://interac.ca/en/about/our-company.html). Quebec is a very proud and independent region and for many historical reasons they want to stand on their own, which is why they support their local systems. Some vendors will support only Interac for debit card transactions (at least this was the case when I stayed there the beginning of this decade, it might have changed a bit). *Most* vendors (including supermarkets like Provigo, Metro, etc) will accept major credit and debit cards, although MasterCard isn t accepted as widely there as Visa is. So, if you have one of both, load up your Visa card instead of your MasterCard or get a prepaid Visa card from your bank. They support chip cards everywhere so don t worry about that. If you have a 5 digit pin on any of your cards and a vendor asks you for a 4 digit pin, it will work 90%+ of the times if you just enter the first 4 digits, but it s usually a good idea to go change your pin to a 4 digit just to be safe.
From the Indian perspective all of the above fits pretty neat as we also have Pin and Chip cards (domestically though most ATMs still use the magnetic strip and is suspected that the POS terminals aren t any better.) That would be a whole different story so probably left for another day. I do like the bit about pocketing the change tip. As far as number of free transactions go, it was pretty limited in India for few years before the demonetization happening now. Few years before, I do remember doing as many transactions on the ATM as I please but then ATM s have seen a downward spiral in terms of technology upgradation, maintenance etc. There is no penalty to the bank if the ATM is out-of-order. If there was significant penalty then we probably would have seen banks taking more care of ATM s. It is a slightly more complex topic hence would take a stab at it some other day. Do hope though that the terms for ATM usage for bank customers become lenient similar to Canada otherwise it would be difficult for Indians to jump on the digital band-wagon as you cannot function without cheap, user-friendly technology. Cash machines: Uneven spread, slowing growth - Copyright Indian Express The image has been taken from this fascinating article which appeared in Indian Express couple of days back. Coming back to the cheese and wine in the evening. I think we started coming back from Eagle Encounters around 16:30/17:00 hrs Cape Town time. Somehow the ride back was much more faster and we played some Bollywood party music while coming back (all cool). Suddenly remembered that I had to buy some cheese as I hadn t bought any from India. There is quite a bit of a post where I m trying to know/understand if spices can be smuggled (which much later I learnt I didn t need to but that s a different story altogether), I also had off-list conversations with people about cheese as well but wasn t able to get any good recommendations. Then saw that KK bought Mysore Pak (apparently she took a chance not declaring it) which while not being exactly cheese fit right into things. In her own words a South Indian ghee sweet fondly nicknamed the blocks of cholesterol and reason #3 for bypass surgery . KK So with Leonard s help we stopped at a place where it looked like a chain of stores. Each store was selling something. Seeing that, I was immediately transported to Connaught Place, Delhi Connaught Place, Delhi The image comes from http://planetden.com/food/roundabout-world-connaught-place-delhi which attempts to explain Connaught Place. While the article is okish, it lacks soul and not written like a Delhite would write or anybody who has spent a chunk having spent holidays at CP. Another day, another story, sorry. What I found interesting about the stores while they were next to each other, I also eyed an alcohol shop as well as an Adult/Sex shop. I asked Leonard as to how far we were from UCT and he replied hardly 5 minutes by car and was shocked to see both alcohol and a sex shop. While an alcohol shop some distance away from a college is understandable, there are few and far around Colleges all over India, but adult shops are a rarity. Unfortunately, none of us have any photos of the place as till that time everybody s phone was dead or just going to be dead and nobody had thought to bring a portable power pack to juice our mobile devices. A part of me was curious to see what the sex shop would have and look from inside, but as was with younger people didn t think it was appropriate. All of us except Jaminy and someone else (besides Leonard) decided to stay back, while the rest of us went inside to explore the stores. It took me sometime to make my way to the cheese corner and had no idea which was good and which wasn t. So with no idea of brands therein, the only way to figure out was the pricing. So bought two, one a larger 500 gm cheap piece and a smaller slightly more expensive one just to make sure that the Debian cheese team would be happy. We did have a mini-adventure as for sometime Jaminy was missing, apparently she went goofing off or went to freshen up or something and we were unable to connect with her as all our phones were dead or dying. Eventually we came back to UCT, barely freshened up when it was decided by our group to go and give our share of goodies to the cheese and wine party. When I went up to the room to share the cheese, came to know they needed a volunteer for cutting veggies etc. Having spent years seeing Yan Can Cook and having practised quite a bit tried to do some fancy decoration and some julian cutting but as we got dull knives and not much time, just did some plain old cutting

I have to share I had a fascinating discussion about cooking in Pressure Cookers. I was under the assumption that everybody knows how to use Pressure Cookers as they are one of the simplest ways to cook food without letting go of all the nutrients. At least, I believe this to be predominant in the Asian subcontinent and even the chinese have similar vessels for cooking. I use what is called the first generation Pressure Cooker. I have been using a 1.5 l Prestige Pressure Cooker over half a decade, almost used daily without issues. http://www.amazon.in/Prestige-Nakshatra-Aluminium-Pressure-Cooker/dp/B00CB7U1OU
Prestige 1.5 L Pressure Cooker

1.5 Litre Pressure Cooker with gasket and everything.

There are also induction pressure cookers nowadays in the Indian market and this model https://www.amazon.in/Prestige-Deluxe-Induction-Aluminum-Pressure/dp/B01KZVPNGE/ref=sr_1_2
Induction base cooking for basmati rice

Best cooker for doing Basmati Biryanis and things like that.

Basmati is long-grain, aromatic rice which most families used in very special occasions such as festivals, marriages, anything good and pure is associated with the rice. I had also shared my lack of knowledge of industrial Microwave Ovens. While I do get most small Microwave Ovens like these , cooking in industrial ovens I simply have no clue. Anyways, after that conversation I went back, freshened up a bit and sometime later found myself in the middle of this
Collection of Wine Bottles

Random selection of wine bottles from all over the world.

Also at times found myself in middle of this
Chocolates all around me.

CHOCOLATES

I tried quite a few chocolates but the best one I liked (don t remember the name) was a white caramel chocolate which literally melted into my mouth. Got the whole died and went to heaven experience . Who said gluttony is bad Or this
French Bread, Wine and chaos

French Bread, Wine and chaos

As can be seen the French really enjoy their bread. I do remember a story vaguely (don t remember if it was a children s fairy tale or something) about how the French won a war through their french bread. Or this
Juices for those who love their health

Juices for those who love their health

We also had juices for the teetotaller or who can t handle drinks. Unsurprisingly perhaps, by the end of the session, almost all the different wines were finito while there was still some juices left to go around. From the Indian perspective, it wasn t at all exciting, there were no brawls, everybody was too civilized and everybody staggered off when they met their quota. As I was in holiday spirit, stayed up late, staggered to my room, blissed out and woke up without any headache. Pro tip Drink lots and lots and lots of water especially if you are drinking. It flushes out most of the toxins and also helps in not having after-morning headaches. If I m going drinking, I usually drown myself in at least a litre or two of water, even if I had to the bathroom couple of times before going to bed. All in all, a perfect evening. I was able to connect/talk with some of the gods whom I had wanted to for a long time and they actually listened. Don t remember if I mumbled something or made some sense in small-talk or whatever I did. But as shared, a perfect evening

Norbert Preining: Cornelia Travnicek Junge Hunde

A novel on late adolescence and self-finding, set on a mixture of stages ranging from Vienna, its Hinterland, to China. The recent book of the Viennese young writer Cornelia Travnicek (official page, WikiPedia) tells a complicated story about finding and loosing your parents.
The main actors, Johanna, always helpful and supportive of those around here, and Ernst, a Chinese adoptive son in Austria, are good friends since early childhood. He sets out to find his parents in China, while she has to deal with profound change in her own world while worrying about his travel and distance. Although in principle a nice and interesting story, I felt that the book is at times weighting too much on sentiments, second hand sentiments, and trying to extend the story. By itself this wouldn t be a problem if the language would be of a great story teller, but in this case it just extends and gave me hard time continue reading. The surprising ending isn t that surprising, a single line 2/3 through the book just let it slip so that it is clear who is the father. All in all not a bad book, but I wouldn t recommend it from the depth of my heart. Still, as Viennese I felt a bit nostalgic with parts of dialect appearing in the book.

Mario Lang: Squarepusher's Shobaleader One

I recently was lucky enough to see one of my long-time favourite drum and bass artists live! Squarepusher! I know and love his music since the late 90s. My girlfriend got us tickets for the Shobaleader One performance at Progy & Bess in Vienna. It was fantastic! 90 minutes of high energy jazz. As a personal memory, I captured one of my favourite Squarepusher tracks, Cooper's World. This is another case of #unseenphotography. While I am usually not very much into jazz, I like this fusion of dnb and jazz very much.

Petter Reinholdtsen: Isenkram updated with a lot more hardware-package mappings

The Isenkram system I wrote two years ago to make it easier in Debian to find and install packages to get your hardware dongles to work, is still going strong. It is a system to look up the hardware present on or connected to the current system, and map the hardware to Debian packages. It can either be done using the tools in isenkram-cli or using the user space daemon in the isenkram package. The latter will notify you, when inserting new hardware, about what packages to install to get the dongle working. It will even provide a button to click on to ask packagekit to install the packages. Here is an command line example from my Thinkpad laptop:
% isenkram-lookup  
bluez
cheese
ethtool
fprintd
fprintd-demo
gkrellm-thinkbat
hdapsd
libpam-fprintd
pidgin-blinklight
thinkfan
tlp
tp-smapi-dkms
tp-smapi-source
tpb
%
It can also list the firware package providing firmware requested by the load kernel modules, which in my case is an empty list because I have all the firmware my machine need:
% /usr/sbin/isenkram-autoinstall-firmware -l
info: did not find any firmware files requested by loaded kernel modules.  exiting
%
The last few days I had a look at several of the around 250 packages in Debian with udev rules. These seem like good candidates to install when a given hardware dongle is inserted, and I found several that should be proposed by isenkram. I have not had time to check all of them, but am happy to report that now there are 97 packages packages mapped to hardware by Isenkram. 11 of these packages provide hardware mapping using AppStream, while the rest are listed in the modaliases file provided in isenkram. These are the packages with hardware mappings at the moment. The marked packages are also announcing their hardware support using AppStream, for everyone to use: air-quality-sensor, alsa-firmware-loaders, argyll, array-info, avarice, avrdude, b43-fwcutter, bit-babbler, bluez, bluez-firmware, brltty, broadcom-sta-dkms, calibre, cgminer, cheese, colord, colorhug-client, dahdi-firmware-nonfree, dahdi-linux, dfu-util, dolphin-emu, ekeyd, ethtool, firmware-ipw2x00, fprintd, fprintd-demo, galileo, gkrellm-thinkbat, gphoto2, gpsbabel, gpsbabel-gui, gpsman, gpstrans, gqrx-sdr, gr-fcdproplus, gr-osmosdr, gtkpod, hackrf, hdapsd, hdmi2usb-udev, hpijs-ppds, hplip, ipw3945-source, ipw3945d, kde-config-tablet, kinect-audio-setup, libnxt, libpam-fprintd, lomoco, madwimax, minidisc-utils, mkgmap, msi-keyboard, mtkbabel, nbc, nqc, nut-hal-drivers, ola, open-vm-toolbox, open-vm-tools, openambit, pcgminer, pcmciautils, pcscd, pidgin-blinklight, printer-driver-splix, pymissile, python-nxt, qlandkartegt, qlandkartegt-garmin, rosegarden, rt2x00-source, sispmctl, soapysdr-module-hackrf, solaar, squeak-plugins-scratch, sunxi-tools, t2n, thinkfan, thinkfinger-tools, tlp, tp-smapi-dkms, tp-smapi-source, tpb, tucnak, uhd-host, usbmuxd, viking, virtualbox-ose-guest-x11, w1retap, xawtv, xserver-xorg-input-vmmouse, xserver-xorg-input-wacom, xserver-xorg-video-qxl, xserver-xorg-video-vmware, yubikey-personalization and zd1211-firmware If you know of other packages, please let me know with a wishlist bug report against the isenkram-cli package, and ask the package maintainer to add AppStream metadata according to the guidelines to provide the information for everyone. In time, I hope to get rid of the isenkram specific hardware mapping and depend exclusively on AppStream. Note, the AppStream metadata for broadcom-sta-dkms is matching too much hardware, and suggest that the package with with any ethernet card. See bug #838735 for the details. I hope the maintainer find time to address it soon. In the mean time I provide an override in isenkram.
