Reproducible builds folks: Reproducible builds: week 61 in Stretch cycle

What happened in the Reproducible Builds effort between June 19th and June 25th 2016. Media coverage GSoC and Outreachy updates Toolchain fixes Other upstream fixes Emil Velikov searched on IRC for hints on how to guarantee unique values during build to invalidate shader caches in Mesa, when also no VCS information is available. A possible solution is a timestamp, which is unique enough for local builds, but can still be reproducible by allowing it to be overwritten with SOURCE_DATE_EPOCH. Packages fixed The following 9 packages have become reproducible due to changes in their build dependencies: cclib librun-parts-perl llvm-toolchain-snapshot python-crypto python-openid r-bioc-shortread r-bioc-variantannotation ruby-hdfeos5 sqlparse The following packages have become reproducible after being fixed: Some uploads have fixed some reproducibility issues, but not all of them: Patches submitted that have not made their way to the archive yet: Package reviews 139 reviews have been added, 20 have been updated and 21 have been removed in this week. New issues found: 53 FTBFS bugs have been reported by Chris Lamb, Santiago Vila and Mateusz ukasik. diffoscope development Quote of the week "My builds are so reproducible, they fail exactly every second time." Johannes Ziemke (@discordianfish) Misc. This week's edition was written by Chris Lamb (lamby), Reiner Herrmann and Holger Levsen and reviewed by a bunch of Reproducible builds folks on IRC.

Russ Allbery: Another small book haul

Book reading is happening, and more book review posting will be happening. I'm a bit behind in writing reviews, but the holiday weekend is a good opportunity to do a bit of catching up. In the meantime, here are some new acquisitions: Roxanne J. Coady & Joy Johannessen (ed.) The Books That Changed My Life (nonfiction)
James S.A. Corey Caliban's War (sff)
James S.A. Corey Abaddon's Gate (sff)
Max Gladstone Full Fathom Five (sff)
Max Gladstone Last First Snow (sff)
N.K. Jemisin The Fifth Season (sff)
Guy Gavriel Kay Children of Earth and Sky (sff)
Naomi Novik Uprooted (sff)
Ada Palmer Too Like the Lightning (sff)
Graydon Saunders Safely You Deliver (sff)
Neal Stephenson Seveneves (sff)
Jeff VanderMeer Annihilation (sff) This is mostly catching up on books that were nominated for awards. I want to read the (legitimate) nominees for Hugo best novel this year if I can find the time, and VanderMeer won the Nebula last year. The rest of Gladstone's series to date was on sale, and I really liked the first book. And of course a new Guy Gavriel Kay is buy on sight. I'm currently re-reading The Sarantine Mosaic, since I read that before I started writing reviews and Children of Earth and Sky is apparently set in historical contact with it. (It's possible all of Kay's historical fantasies are set in the same universe, but they're usually fairly disconnected.)

Neil Williams: Moving to Pelican

Prompted by Tollef, moving to Hugo, I investigated a replacement blog engine. The former site used Wordpress which is just overhead - my blog doesn't need to be generated on every view, it doesn't need the security implications of yet another website login and admin interface either. The blog is static, so I've been looking at static generators. I didn't like the look of Hugo and wanted something where the syntax was familiar - so either Jinja2 or ReST. So, I've chosen Pelican with the code living in a private git repo, naturally. I wanted a generator that was supported in Jessie. I first tried nikola but it turns out that nikola in jessie has syntax changes. I looked at creating backports but then there is a new upstream release which adds a python module not yet in Debian, so that would be an extra amount of work. Hopefully, this won't flood planet - I've gone through the RSS content to update timestamps but the URLs have changed.

Tollef Fog Heen: Blog moved, new tech

I moved my blog around a bit and it appears that static pages are now in favour, so I switched to that, by way of Hugo. CSS and such needs more tweaking, but it ll make do for now. As part of this, RSS feeds and such changed, if you want to subscribe to this (very seldomly updated) blog, use https://err.no/personal/blog/index.xml

Enrico Zini: Praise of component reuse

I farm bits and pieces out to the guys who are much more brilliant than I am. I say, "build me a laser", this. "Design me a molecular analyzer", that. They do, and I just stick 'em together. (Seth Brundle, "The Fly")
When I decided to try and turn siterefactor into staticsite, I decided that I would go ahead only for as long as it could be done with minimal work, writing code in the most straightforward way on top of existing and stable components. I am pleased by how far that went. Python-Markdown It works fast enough, already comes with extensions for most of what I needed, and can be extended in several ways. One of the extension methods is a hook for manipulating the ElementTree of the rendered document before serializing it to HTML, which made it really easy to go and process internal links in all <a href= and <img src= attributes. To tell an internal link from an external link I just use the standard python urlparse and see if the link has a scheme or a netloc component. If it does not, and if it has a path, then it is an internal link. This also means that I do not need to invent new Markdown syntax for internal references, avoiding the need for remembering things like [text]( < relref "blog/post.md" > ) or [text]( filename /blog/post.md). In staticsite, it's just [text](/blog/post.md) or [text](post.md) if the post is nearby. This feels nicely clean to me: if I wanted to implement fancy markdown features, I could do it as Python-Markdown extensions and submit them upstream. If I wanted to implement fancy interlinking features, I could do it with a special url scheme in links. For example, it would be straigtforward to implement a ssite: url scheme that expanded the url with elements from staticsite's settings using a call to python's string.format (ssite: SETTING_NAME /bar maybe?), except I do not currently see any use cases for extending internal linking from what it is now. Jinja2 Jina2 is a template engine that I already knew, it is widely used, powerful and pleasant to use, both on the templating side and on the API's side. It is not HTML specific, so I can also use it to generate Atom, RSS2, "dynamic" site content, and even new site Markdown pages. Implementing RSS and Atom feeds was just a matter of writing and testing these Jinja2 macros and then reusing them anywhere. toml, yaml, json No need to implement my own front matter parsing. Also, reusing the same syntax as Hugo allows me to just link to its documentation. python-slugify I found python-slugify so I did not bother writing a slug-generating function. As a side effect, now things works better than I would even have thought to implement, including transliteration of non-ascii characters: 
$ ./ssite new example --noedit --title "Cos  parl  Enrico"
/enrico-dev/staticsite/example/site/blog/2016/cosi-parlo-enrico.md
(I just filed an RFP) python-livereload Implementing ssite serve which monitors the file system and autoreloads when content changes and renders everything on the fly, took about an hour. Most of that hour went into implementing rendering pages on demand. Then I discovered that it autoreloads even when I edit staticsite's source code. Then I discovered that it communicates with the browser and even automatically triggers a page refresh. I can keep vim on half my screen and a browser in the other half, and I get live preview for free every time I save, without ever leaving the editor. Bootstrap I already use Bootstrap at work, so creating the default theme templates with it took about 10 minutes. This morning I tried looking at my website using my mobile phone, and I pleasantly saw it automatically turning into a working mobile version of itself. Pygments Python-Markdown uses Pygments for syntax highlighting, and it can be themed just by loading a .css. So, without me really doing anything, even staticsite's syntax highligthing is themable, and there's even a nice page with a list of themes to choose from. Everything else... Command line parsing? Straight argparse. Logging? python's logging support. Copying static resource files? shutil.copy2. Parsing dates? dateutil.parser. Timing execution? time.perf_counter. Timezone handling? pytz. Building the command to run an editor? string.format. Matching site pages? fnmatch.translate. ...and then some. If I ever decide to implement incremental rendering, how do I implement tracking which source files have changed? Well, for example, how about just asking git?

Enrico Zini: Static site generators

I decided to rethink the state of my personal site, and try out some of the new static site generators that are available now. To do that, I jotted down a series of things that I want in a static site generator, then wrote a tool to convert my ikiwiki site to other formats, and set out to evaluate things. As a benchmark I did a full rebuild of my site, which currently contains 1164 static files and 458 markdown pages. My requirements Free layout for my site My / is mostly a high-level index to the site contents. Blog posts are at /blog. My talk archive is organised like a separate blog at /talks. I want the freedom to create other sections of the site, each with its own rss feed, located wherever I want in the site hierarchy. Assets next to posts I occasionally blog just a photo with a little comment, and I would like the .md page with the comment to live next to the image in the file system. I did not even know that I had this as a requirement until I found static site generators that mandated a completely different directory structure for markdown contents and for static assets. Multiple RSS/Atom feeds I want at least one RSS/Atom feed per tag, because I use tags for marking which articles go to http://planet.debian.org. I also want RSS/Atom feeds for specific parts of the site, like the blog and talks. Arbitrary contents in /index.html I want total control over the contents of the main home page of the site. Quick preview while editing contents I do not like to wait several seconds for the site to be rebuilt at every review iteration of the pages I write. This makes me feel like the task of editing is harder than it should, and makes me lose motivation to post. Reasonable time for a full site rebuild I want to be able to run a full rebuild of the site in a reasonable time. I could define "reasonable" in this case as how long I can stare at the screen without getting bored, starting to do something else, and forgetting what it was that I was doing with the site. It is ok if a rebuild takes something like 10 or 30 seconds. It is not ok if it takes minutes. Code and dependency ecosystems that I can work with I can deal with Python and Go. I cannot deal with Ruby or JavaScript. I forgot all about Perl. Also, if it isn't in Debian it does not exist. Decent themes out of the box One of my hopes in switching to a more mainstream generator is to pick and choose themes and easily give my site a more modern look. Hugo Hugo is written in Go and is in Debian testing. Full rebuild time for my site is acceptable, and it can even parallelize: 
  $ time hugo
  real      0m5.285s
  user      0m9.556s
  sys       0m1.052s
Free layout for my site was hard to get. I could replace /index.html by editing the template page for it, but then I did not find out how to create another similar index in an arbitrary place. Also, archetypes are applied only on the first path component of new posts, but I would like them instead to be matched on the last path component first, and failing that traveling up to the path until the top. This should be easy to fix by reorganizing the content a bit around here For example, a path for a new blog post of mine could be blog/2016/debian/ and I would like it to match the debian archetype first, and failing that the blog archetype. Assets next to posts almost work. Hugo automatically generates one feed per taxonomy element, and one feed per section. This would be currently sufficient for me, although I don't like the idea that sections map 1 to 1 to toplevel directories in the site structure. Hugo has a server that watches the file system and rerenders pages as they are modified, so the quick preview while editing works fine. About themes, it took me several tries to find a theme that would render navigation elements for both sections and tags, and most themes would render by pages with white components all around, and expect me to somehow dig in and tweak them. That frustrated me, because for quite a while I could not tell if I had misconfigured Hugo's taxonomies or if the theme was just somehow incomplete. Nikola Nikola is written in Python and is in Debian testing. Full rebuild time for my site is almost two orders of magnitude more than Hugo, and I am miffed to find the phrases "Nikola is fast." or "Fast building process" in its front page and package description: 
  $ time nikola build
  real      3m31.667s
  user      3m4.016s
  sys       0m24.684s
Free layout could be achieved fiddling with the site configuration to tell it where to read sources. Assets next to post work after tweaking the configuration, but they require to write inconsistent links in the markdown source: https://github.com/getnikola/nikola/issues/2266 I have a hard time accepting that that, because I want to author content with consistent semantic interlinking, because I want to be able 10 years from now to parse it and convert it to something else if a new technology comes out. Nikola generates one RSS/Atom feed per tag just fine. I have not tried generating feeds for different sections of the site. Incremental generation inside its built in server works fine. Pelican Pelican is written in Python and is in Debian testing. Full rebuild time for my site is acceptable: 
  $ time pelican -d
  real      0m18.207s
  user      0m16.680s
  sys       0m1.448s
By default, pelican seems to put generate a single flat directory of html files regardless of the directory hierarchy of the sources. To have free layout, pelican needs some convincing in the configuration: 
  PATH_METADATA = r"(?P<relpath>.+)\.md"
  ARTICLE_SAVE_AS = " relpath /index.html"
but even if I do that, the urls that it generates still point to just slug /index.html and I have not trivially found a configuration option to fix that accordingly. I got quite uncomfortable at the idea of needing to configure content generation and linking to match, instead of having one automatically being in sync with the other. Having assets next to posts seems to be possible (also setting STATIC_PATHS = ["."]), but I do not recall making progress on this front. I did not manage to generate a feed for each tag out of the box, and probably there is some knob in the configuration for it. I gave up with Pelican as trying it out felt like a constant process of hacking the configuration from defaults that do not make any sense for me, withouth even knowing if a configuration exists that would do what I need Ikiwiki Ikiwiki is written in Perl and is in Debian. Although I am not anymore proficient with Perl, I was already using it, so it was worth considering. Full rebuild time feels a bit on the slow side but is still acceptable: 
  $ time ikiwiki --setup site.setup
  real      0m37.356s
  user      0m34.488s
  sys       0m1.536s
In terms of free site structure, all feeds for all or part of the site, ikiwiki just excels. I even considered writing a python web server that monitors the file system and calls ikiwiki --refresh when anything changes, and calling it a day. However, when I tried to re-theme my website around a simple bootstrap boilerplate, I found that to be hard, as a some of the HTML structure is hardcoded in Perl (and it's also my fault) and there is only so much that can be done by tweaking the (rather unreadable) templates. siterefactor During all these experiments I had built siterefactor to generate contents for all those static site engines, and it was going through all the contents quite fast: 
  $ time ./siterefactor src dst -t hugo
  real  0m1.222s
  user  0m0.904s
  sys   0m0.308s
So I wondered how slow it would become if, instead of making it write markdown, I made it write HTML via python markdown and Jinja2: 
  $ time ./siterefactor ~/zz/ikiwiki/pub/ ~/zz/ikiwiki/web -t web
  real  0m6.739s
  user  0m5.952s
  sys   0m0.416s
I then started wondering how slower it would become if I implemented postprocessing of all local URLs generated by Markdown to make sure they are kept consistent even if the path of a generated page is different than the path of its source. Not much slower, really. I then added taxonomies. And arbitrary Jinja2 templates in the input, able to generate page lists and RSS/Atom feeds. And theming. And realised that reading all the sources and cross-linking them took 0.2 seconds, and the rest was generation time. And that after cross-linking, each page can be generated independently from all the others. staticsite So my site is now generated with staticsite: 
  $ time ssite build
  real  0m6.833s
  user  0m5.804s
  sys   0m0.500s
It's comparable with Hugo, and on a single process.

Chris Lamb: Free software activities in January 2016

Here is my monthly update covering a large part of what I have been doing in the free software world (previously):
Debian
  • Had a talk proposal accepted (Reproducible Builds - fulfilling the original promise of free software) at FOSSASIA 16.
My work in the Reproducible Builds project was also covered in more depth in Lunar's weekly reports (#35, #36, #37, #38, #39)
LTS

This month I have been paid to work 18 hours on Debian Long Term Support (LTS). In that time I did the following:
  • Sevend days of "frontdesk" duties, triaging CVEs, etc.
  • Issued DLA 386-1 for cacti to patch an SQL injection vulnerability.
  • Issued DLA 388-1 for dwarfutils fixing a NULL deference issue.
  • Issued DLA 391-1 for prosody correcting the use of a weak pseudo-random number generator.
  • Issued DLA 404-1 for nginx to prevent against an invalid pointer deference.
Uploads
  • redis (2:3.0.7-1) New upstream stable release, also ensure that test processes are cleaned up and replacing an existing reproducibility patch with a SOURCE_DATE_EPOCH solution.
  • python-django (1.9.1-1) New upstream release.
  • disque (1.0~rc1-4) Make the build reproducible via SOURCE_DATE_EPOCH, ensure that test processes are cleaned up and that the nocheck flag is correctly honoured.

Bernd Zeimetz: bzed.de online again

Finally, bzed.de is back online and I m planning to start blogging again! Part of the reason why I became inactive was the usage of ikiwiki, which is great, but at end unnecessarily complicated. So I ve migrated by page to gohugo.io - a static website generator, written in go. Hugo has an active community and it is easy to create themes for it or to enhance it. Also it is using plain Markdown syntax instead of special ikiwiki syntax mixed into it - should make it easy to migrate away again if necessary. In case somebody else would like to convert from ikiwiki to Hugo, here is the script I ve hacked together to migrate my old blog posts. 

#!/bin/bash
find . -type f -name '*.mdwn'   while read i; do
    tmp= mktemp 
     
        echo '+++'
        slug="$(echo $i   sed 's,.*/,,;s,\.mdwn$,,')"
        echo "slug = \"$ slug \""
        echo "title = \"$(echo $i   sed 's,.*/,,;s,\.mdwn$,,;s,_, ,g;s/\b\(.\)/\u\1/;s,debian,Debian,g')\""
        if grep -q 'meta updated' $i; then
            echo -n 'date = '
            sed '/meta updated/!d;/.*meta updated.*/s,.*=",,;s,".*,,;s,^,",;s,$,",' $i
        else
            echo -n 'date = '

Lunar: Reproducible builds: week 22 in Stretch cycle

What happened in the reproducible builds effort this week: Toolchain fixes Packages fixed The following 22 packages became reproducible due to changes in their build dependencies: breathe, cdi-api, geronimo-jpa-2.0-spec, geronimo-validation-1.0-spec, gradle-propdeps-plugin, jansi, javaparser, libjsr311-api-java, mac-widgets, mockito, mojarra, pastescript, plexus-utils2, powerline, python-psutil, python-sfml, python-tldap, pythondialog, tox, trident, truffle, zookeeper. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues but not all of them: Patches submitted which have not made their way to the archive yet: diffoscope development The changes to make diffoscope run under Python 3, along with many small fixes, entered the archive with version 35 on September 21th. Another release was made the very next day fixed two encoding-related issues discovered when running diffoscope on more Debian packages. strip-nondeterminism development Version 0.12.0 now preserves file permissions on modified zip files and dh_strip_nondeterminism has been made compatible with older debhelper. disorderfs development Version 0.3.0 implemented a multi-user mode that was required to build Debian packages using disorderfs. It also added command line options to control the ordering of files in directory (either shuffled or reversed) and another to do arbitrary changes to the reported space used by files on disk. A couple days later, version 0.4.0 was released to support locks, flush, fsync, fsyncdir, read_buf, and write_buf. Almost all known issues have now been fixed. reproducible.debian.net disorderfs is now used during the second build. This makes file ordering issue very easy to identify as such. (h01ger) Work has been done on making the distributed build setup more reliable. (h01ger) Documentation update Matt Kraii fixed the example on how to fix issues related to dates in Sphinx. Recent Sphinx versions should also be compatible with SOURCE_DATE_EPOCH. Package reviews 53 reviews have been removed, 85 added and 13 updated this week. 46 packages failing to build from source has been identified by Chris Lamb, Chris West, and Niko Tyni. Chris Lamb was the lucky reporter of bug #800000 on vdr-plugin-prefermenu. Issues related to disorderfs are being tracked with a new issue.

Russ Allbery: Review: The Goblin Emperor

Review: The Goblin Emperor, by Katherine Addison
Publisher: Tor

Maia is the child of the current emperor of the Elflands, but not a favored one. He's the half-goblin son of a political marriage to a goblin princess, quickly orphaned away from the capital and kept in seclusion well out of the way of his father and court politics. And in the care of his cousin Setheris: cruel and abusive companionship. Then the airship Wisdom of Choharo crashes with no survivors, killing everyone in the line of succession. Except Maia. Maia is in no way prepared to be emperor, but the rules of succession are clear: he is now emperor. We all know from medieval history, both real and fantastic, that clear rules rarely got in the way of aggressive political maneuvering, but Maia's short-term survival is helped considerably by complex factions at play at court (of which he is almost wholly ignorant), and a certain lack of bloodthirstiness in elven politics. Rather than disposing of the unexpected heir, people instead start maneuvering to manipulate and control him. The current Lord Chancellor is the first, beginning his play in the message sent informing Maia of his father's death, and his cousin isn't far behind, but they're only the first two. Meanwhile, Maia, who had never been trained for any sort of court life, has to learn nearly everything about his new life: how to interact with servants, the rituals of court, his new duties, and all of the factions in play. One might expect that Maia would quickly be reduced to a pawn of one faction or another, but he has two secret weapons. One is that he is a legitimately nice person with a strongly developed sense of empathy. Early on, he lucks into some opportunities to show this and wins some popularity and some allies of his own, particularly among those people not used to being treated with respect. And two, he's had enough of his cousin controlling and abusing him. He's determined to make his own decisions and not take orders from someone else, and now has enough nominal power to possibly pull this off. The Goblin Emperor is a fantasy of political agency, and a story about political maneuvering, tricky decisions, navigating alliances, and learning politics. There isn't a lot of action here: most of the plot happens in conversation. The tension is high Maia's situation is precarious but it mostly involves second-guessing his decisions and actions, and hoping that his weaknesses and ignorance don't get him into too much trouble. That is an extremely tricky book to write. Addison had to walk a tightrope between letting Maia's new responsibilities come unrealistically easily, making him seem like a Chosen One with special plot powers, and having readers get too frustrated with realistically bad decisions and lose their desire to read about him. Addison walks that tightrope magnificently. I liked Maia throughout this book, and that's the strength of it. He never felt like the typical fantasy coming of age hero who is magically protected by the plot. He's just a genuine, honest person, reacting to his own past as best he can, making the best decisions he knows how to make. He makes mistakes, but Addison wisely avoids making those mistakes cringe-worthy or too obvious. Instead, they're like bad moves in a chess match: they create problems but also some opportunities, and they're realistically recoverable. And it's a delight to see Maia bring empathy and a disinterested outside perspective to the hothouse mess of court politics and come up with some very creative solutions. Obviously, the situation that allows Maia to succeed is artificial. This is a fantasy: Maia happens to be just the right person the empire needs, and that's clearly an authorial construction. It may be impossible to write a political story about a well-meaning, naive outsider that isn't a tragedy without a bit of cheating. But Addison hides the cheating well. Maia may be very lucky in the empire he inherits, but it feels coherent and believable. By the end of the book, Maia has dealt with everything from international diplomacy to the incredibly complex negotiations around further heirs to the empire. And (realistically) he doesn't stay lucky throughout the book: eventually, no matter how careful he tries to be, he angers some powerful people. I enjoyed every step along the way, and would have happily read more about Maia. In my personal ranking, this was second only to Ancillary Sword in the nominees for the 2015 Hugo, and I wouldn't disagree too strongly with someone who argued it was better. It's not a typical sort of fantasy, but it's one I enjoyed very much. Recommended. One warning: consider going to the back of the book and reading the glossary at the start. There may be some mild spoilers in there, but it also explains the title conventions in the empire, and some of those titles look very much like proper names. If, like me, you don't read this until the end of the book, you may find yourself horribly confused by several apparently similarly-named characters. Rating: 8 out of 10

Russell Coker: BTRFS Status June 2015

The version of btrfs-tools in Debian/Jessie is incapable of creating a filesystem that can be mounted by the kernel in Debian/Wheezy. If you want to use a BTRFS filesystem on Jessie and Wheezy (which isn t uncommon with removable devices) the only options are to use the Wheezy version of mkfs.btrfs or to use a Jessie kernel on Wheezy. I recently got bitten by this issue when I created a BTRFS filesystem on a removable device with a lot of important data (which is why I wanted metadata duplication and checksums) and had to read it on a server running Wheezy. Fortunately KVM in Wheezy works really well so I created a virtual machine to read the disk. Setting up a new KVM isn t that difficult, but it s not something I want to do while a client is anxiously waiting for their data. BTRFS has been working well for me apart from the Jessie/Wheezy compatability issue (which was an annoyance but didn t stop me doing what I wanted). I haven t written a BTRFS status report for a while because everything has been OK and there has been nothing exciting to report. I regularly get errors from the cron jobs that run a balance supposedly running out of free space. I have the cron jobs due to past problems with BTRFS running out of metadata space. In spite of the jobs often failing the systems keep working so I m not too worried at the moment. I think this is a bug, but there are many more important bugs. Linux kernel version 3.19 was the first version to have working support for RAID-5 recovery. This means version 3.19 was the first version to have usable RAID-5 (I think there is no point even having RAID-5 without recovery). It wouldn t be prudent to trust your important data to a new feature in a filesystem. So at this stage if I needed a very large scratch space then BTRFS RAID-5 might be a viable option but for anything else I wouldn t use it. BTRFS still has had little performance optimisation, while this doesn t matter much for SSD and for single-disk filesystems for a RAID-5 of hard drives that would probably hurt a lot. Maybe BTRFS RAID-5 would be good for a scratch array of SSDs. The reports of problems with RAID-5 don t surprise me at all. I have a BTRFS RAID-1 filesystem on 2*4TB disks which is giving poor performance on metadata, simple operations like ls -l on a directory with ~200 subdirectories takes many seconds to run. I suspect that part of the problem is due to the filesystem being written by cron jobs with files accumulating over more than a year. The btrfs filesystem command (see btrfs-filesystem(8)) allows defragmenting files and directory trees, but unfortunately it doesn t support recursively defragmenting directories but not files. I really wish there was a way to get BTRFS to put all metadata on SSD and all data on hard drives. Sander suggested the following command to defragment directories on the BTRFS mailing list: find / -xdev -type d -execdir btrfs filesystem defrag -c + Below is the output of zfs list -t snapshot on a server I run, it s often handy to know how much space is used by snapshots, but unfortunately BTRFS has no support for this.

Hugo pointed out on the BTRFS mailing list that the following command will give the amount of space used for snapshots. $SNAPSHOT is the name of a snapshot and $LASTGEN is the generation number of the previous snapshot you want to compare with. btrfs subvolume find-new $SNAPSHOT $LASTGEN awk ' total = total + $7 END print total ' One upside of the BTRFS implementation in this regard is that the above btrfs command without being piped through awk shows you the names of files that are being written and the amounts of data written to them. Through casually examining this output I discovered that the most written files in my home directory were under the .cache directory (which wasn t exactly a surprise). Now I am configuring workstations with a separate subvolume for ~/.cache for the main user. This means that ~/.cache changes don t get stored in the hourly snapshots and less disk space is used for snapshots. Conclusion My observation is that things are going quite well with BTRFS. It s more than 6 months since I had a noteworthy problem which is pretty good for a filesystem that s still under active development. But there are still many systems I run which could benefit from the data integrity features of ZFS and BTRFS that don t have the resources to run ZFS and need more reliability than I can expect from an unattended BTRFS system. At this time the only servers I run with BTRFS are located within a reasonable drive from my home (not the servers in Germany and the US) and are easily accessible (not the embedded systems). ZFS is working well for some of the servers in Germany. Eventually I ll probably run ZFS on all the hosted servers in Germany and the US, I expect that will happen before I m comfortable running BTRFS on such systems. For the embedded systems I will just take the risk of data loss/corruption for the next few years.

Russ Allbery: Catch-up haul

As always, even though I've not been posting much, I'm still buying books. This is a catch-up post listing a variety of random purchases. Katherine Addison The Goblin Emperor (sff)
Milton Davis From Here to Timbuktu (sff)
Mark Forster How to Make Your Dreams Come True (non-fiction)
Angela Highland Valor of the Healer (sff)
Marko Kloos Terms of Enlistment (sff)
Angela Korra'ti Faerie Blood (sff)
Cixin Liu The Three-Body Problem (sff)
Emily St. John Mandel Station Eleven (sff)
Sydney Padua The Thrilling Adventures of Lovelace and Babbage (graphic novel)
Melissa Scott & Jo Graham The Order of the Air Omnibus (sff)
Andy Weir The Martian (sff) Huh, for some reason I thought I'd bought more than that. I picked up the rest of the Hugo nominees that aren't part of a slate, and as it happens have already read all the non-slate nominees at the time of this writing (although I'm horribly behind on reviews). I also picked up the first book of Marko Kloos's series, since he did the right thing and withdrew from the Hugos once it became clear what nonsense was going on this year. The rest is a pretty random variety of on-line recommendations, books by people who made sense on the Internet, and books by authors I like.

Russ Allbery: Review: Wakulla Springs

Review: Wakulla Springs, by Andy Duncan & Ellen Klages
Publisher: Tor
Copyright: October, 2013
ASIN: B00EWZDPH4
Format: Kindle
Pages: 99
This is another nominee for the 2014 Hugo Awards (for works published in 2013), this time in the novella category. In this case, though, I read the free ebook version from Tor (Macmillan) rather than the version from the voter packet, since I usually grab all the free ebooks of Tor.com stories. (Even if I'm quite behind in reading them, since I don't read much short fiction.) As an independently-published novella, it gets its own review in the book category. Wakulla Springs is the story of three generations (and four protagonists) who lived near or visited Wakulla Springs in the Florida panhandle. This is a real place: a huge freshwater springs and underwater cave system, now protected as a national park. Two of the four episodes in this story revolve around the filming of movies: a Tarzan movie and Creature from the Black Lagoon. This actually happened as well, although of course the story takes liberties with the details. This is also the story of race relations in the American deep south: the tense and uncertain interactions between black locals and rich white people, both locals and people from the film industry who came for a brief time and then left again. It's also a story about water, swimming, and the sense of being part of the water and knowing it well. This story doesn't develop any particular point; rather, it's more of a collection of character sketches, grabbing moments in time, glimpsing what it's like to cross racial barriers and to feel at home with one's choices. It's also, in a nicely subtle way, about encountering mythical creatures that are not part of one's world. To the locals, the film stars who visit Wakulla Springs are as wild and strange as the imagined creatures of the swamp, and in their way even more foreign. What this is not, though, is science fiction, or even fantasy. One of the complaints I'd heard about Wakulla Springs in the context of the Hugos was that it didn't qualify as a genre story. I'm usually inclined to dismiss these sorts of complaints, since they're often put forth by people with a far narrower definition of genre than mine. But, having read this story, I have to concur. It's very well-written and engaging, but it's not genre in any sense that I'd define it. There are some rare mentions of mythical creatures, but only in ways that are part of the setting, and which are no more fantastic than I'd expect from many mainstream stories. I'm a bit baffled why an SFF publisher would have bought it for an explicitly SFF forum; I have to assume that it's just because it's well-written and the authors have both written SFF. That said, even though this is not the sort of story I'd normally seek out, I'm still glad I read it. I thought the best part of the story was the first, which follows a black woman who takes a job at the Wakulla Springs resort during the filming of a Tarzan movie. The color lines are simply taken for granted by everyone, but Johnny Weissmuller comes off very well in his fictional representation and adds an enthusiastic energy that plays off well against the thoughtful care of the protagonist. The second part echoes this with a boy as the protagonist, but shifts a generation later. This means the color line is fought instead of simply assumed, although with limited success. I thought this part of the story had the best descriptions of the joy of swimming, and once again the movie folks bring a disruptive and positive change to the tightly-drawn lines of local roles and politics. The third and fourth parts I found slighter, elaborating on the story by showing the reader glimpses of the later life of the first two protagonists, but not, I thought, adding anything fundamental to the story. I'm not sure this would be satisfying if you were looking for a science fiction or fantasy story, but it's a solid mainstream story about race, class, and the joy of knowing and feeling a place. It captures an angle of Hollywood that I've rarely seen in movies: a disruptive and almost subversive playfulness and energy that doesn't fix problems but that does provide moments of escape from the realities of the world, even outside of the film. Worth reading, particularly since it's free. Rating: 7 out of 10

Russ Allbery: Review: 2014 Hugos: Novelettes

Review: 2014 Hugos: Novelettes, edited by Loncon 3
Publisher: Loncon 3
Copyright: 2014
Format: Kindle
This is another weird "book review" covering the Hugo-nominated novelettes for the 2014 Hugos (given for works published in 2014) at Loncon 3, the 2014 Worldcon. The "editor" is the pool of attendees and supporting members who chose to nominate works, all of which had been previously edited by other editors in their original publication. I received all of these as part of the Hugo voter's packet for being a supporting member, but they all appear to be available for free on the Internet (at least at the time of this writing). "The Exchange Officers" by Brad Torgersen: An okay, if not particularly ground-breaking, military SF story, ruined for me by the ham-handed introduction of superficial jingoism. The protagonists are doing a tour as remote operators of humanoid battle suits in orbit: not a new premise, but a servicable one. Since this is military SF, they predictably have to defend a space installation against attackers. So we get a bit of drama, a bit of zero-g combat, and the fun of people learning how to remotely operate suits. You've probably read this before, but it passes the time reasonably well. Unfortunately, Torgersen decided to make the villains the Chinese military for no adequately-explained reason. (Well, I'm being kind; I suspect the reason is the standard yellow peril nonsense, but that's less generous.) So there is snide commentary about how only the military understand the Chinese threat and a fair bit of old-fashioned jingoism mixed in to the story, to its detriment. If you like this sort of thing, it's a typical example, although it escapes me why people thought it was exceptional enough to warrant nomination. (5) "The Lady Astronaut of Mars" by Mary Robinette Kowal: Once again, my clear favorite among the stories also won, which is a lovely pattern. Elma was the female astronaut in an alternate history in which manned space exploration continued to grow, leading to permanent settlement on Mars. She spent lots of time being photographed, being the smiling face of the space program, while her husband worked on the math and engineering of the launches. Now, she's an old woman, taking care of her failing and frail husband, her career behind her. Or so she thinks, before an offer that forces an impossible choice between space and staying with her husband for his final days. This is indeed the tear-jerker that it sounds like, but it's not as maudlin as it might sound. Kowal does an excellent job with Elma's characterization: she's no-nonsense, old enough to be confident in her opinions, and knows how to navigate through the world. The story is mixed with nostalgia and memories, including a reminder of just what Elma meant to others. It touches on heroism, symbolism, and the horrible choices around dying loved ones, but I thought it did so deftly and with grace. I was expecting the story to be too obvious, but I found I enjoyed the quotidian feel. It's not a story to read if you want to be surprised, but I loved the small touches. (9) "Opera Vita Aeterna" by Vox Day: Before the review, a note that I consider obligatory. The author of this story is an aggressively misogynistic white supremacist, well-known online for referring to black people as savages and arguing women should not be allowed to vote. To what extent you choose to take that into account when judging his fiction is up to you, but I don't think it should go unsaid. "Opera Vita Aeterna" is the story of a monastery in a typical fantasy world (at least as far as one can tell from this story; readers of Vox Day's fantasy series will probably know more background). At the start of the story, it gets an unexpected visit from an elf. Not just any elf, either, but one of the most powerful magicians of his society. He comes to the monastery out of curiousity about the god that the monks worship and stays for a project of illuminating their scriptures, while having theological debates with the abbot. This story is certainly not the offensive tirade that you might expect from its author. Its biggest problem is that nothing of substance happens in the story, either theologically or via more conventional action. It's a lot of description, a lot of talking, a lot of warmed-over Christian apologetics that dodges most of the hard problems, and a lot of assertions that the elf finds something of interest in this monastery. I can believe this could be the case, but Vox Day doesn't really show why. There is, at the end of the story, some actual drama, but I found it disappointing and pointless. It leads nowhere. The theology has the same problem: elves supposedly have no souls, which is should be the heart of a theological question or conflict Vox Day is constructing, but that conflict dies without any resolution. We know nothing more about the theology of this world at the end of the story than we do at the beginning. Some of the descriptions here aren't bad, and the atmosphere seems to want to develop into a story. But that development never happens, leaving the whole work feeling fundamentally pointless. (4) "The Truth of Fact, the Truth of Feelng" by Ted Chiang: This is another oddly-constructed story, although I think a bit more successful. It's a story in two interwoven parts. One is a fictional essay, told in a non-fiction style, about a man living in a future world with ubiquitous life recording and very efficient search software. Any part of one's life can be easily found and reviewed. The other is the story of a boy from a tribal culture during European colonialism. He learns to read and write, and from that a respect for written records, which come into conflict with the stories that the tribe elders tell about the past. The purpose of both of these stories is to question both the value and the implications of recording everything in a way that preserves and guarantees the facts instead of individual interpretations. The boy's story calls this into question; the narrator's story offers ambiguous support for its value and a deeper plea for giving people space to change. I found the style a bit difficult to get used to, since much of it did not feel like a story. But it grew on me as I read it, and the questions Chiang raises have stuck with me since. The problem of how and when to allow for change in others when we have perfect (or at least vastly improved) memory is both important and complicated, and this is one of the better presentations of the problem that I've seen. It's more of a think-y piece, and closer to non-fiction than a story, but I thought it was worth reading. (8) "The Waiting Stars" by Aliette de Bodard: I keep wanting to like de Bodard's space opera world of AIs and living ships, but it never quite works for me. I've read several stories set in this universe now, and it has some neat ideas, but I always struggle with the characters. This story at least doesn't have quite as much gruesome pregnancy as the previous ones (although there's still some). "The Waiting Stars" opens with a raid on a ship graveyard, an attempt to rescue and "reboot" an AI starship under the guidance of another Mind. This is intermixed with another story about a woman who was apparently rescued in childhood from birthing ship Minds and raised in a sort of foster institution. This feels like a flashback at first, but its interaction with the rest of the story is something more complicated. The conceptual trick de Bodard pulls here is thought-provoking, but once again I struggled to care about all of the characters. I also found the ending discouraging and unsatisfying, which didn't help. Someone who isn't me might really like this story, but it wasn't my thing. (6) Rating: 6 out of 10

Russ Allbery: Review: 2014 Hugos: Short Story Nominees

Review: 2014 Hugos: Short Story Nominees, edited by Loncon 3
Publisher: Loncon 3
Copyright: 2014
Format: Kindle
This is a bit of a weird "book review," since this is not a book. Rather, it's the collection of Hugo-nominated short stories for the 2014 Hugos (given for works published in 2013) at Loncon 3, the 2014 Worldcon. As such, the "editor" is the pool of attendees and supporting members who chose to nominate works, all of which had been previously edited by other editors in their original publication. This is also not something that someone else can acquire; if you were not a supporting or attending member, you didn't get the voting packet. But I believe all of the stories here are available on-line for free in some form, a short search away. "If You Were a Dinosaur, My Love" by Rachel Swirsky: The most common complaint about this story is that it's not really a story, and I have to agree. It's a word image of an alternate world in which the narrator's love is a human-sized dinosaur, starting with some surreal humor and then slowly shifting tone as it reveals the horrible event that's happened to the narrator's actual love, and that's sparked the wish for her love to have claws and teeth. It's reasonably good at what it's trying to do, but I wanted more of a story. The narrator's imagination didn't do much for me. (5) "The Ink Readers of Doi Saket" by Thomas Olde Heuvelt: At least for me, this story suffered from being put in the context of a Hugo nominee. It's an okay enough story about a Thai village downstream from a ritual that involves floating wishes down the river, often with offerings in the improvised small boats. The background of the story is somewhat cynical: the villagers make some of the wishes come true, sort of, while happily collecting the offerings and trying to spread the idea that the wishes with better offerings are more likely to come true. The protagonist follows a familiar twist: he actually can make wishes come true, maybe, but is very innocent about his role in the world. This is not a bad story, although stories written by people with western-sounding names about non-western customs worry me, and there were a few descriptions and approaches here (such as the nickname translations in footnotes and the villager archetypes) that made my teeth itch. But it is not a story that belongs on the Hugo nomination slate, at least in my opinion. It's either cute or mildly irritating, depending on one's mood when one meets it, not horribly original, and very forgettable. (5) "Selkie Stories Are for Losers" by Sofia Samatar: I really liked this story for much of its length. It features a couple of young, blunt, and bitter women, and focuses on the players in the typical selkie story that don't get much attention. The selkie's story is one of captivity or freedom; her lover's story is the inverse, the captor or the lover. But I don't recall a story about the children before, and I think Samatar got the tone right. It has the bitterness of divorce and abandonment mixed with the disillusionment of fantasy turned into pain. My problem with this story is the ending, or rather, the conclusion, since the story doesn't so much end as stop. There's a closing paragraph that gives some hint of the shape to come, but it gave me almost no closure, and it didn't answer any of the emotional questions that the rest of the story raised for me. I wanted something more, some sort of epiphany or clearer determination. (7) "The Water That Falls on You from Nowhere" by John Chu: This was by far my favorite of the nominees, which is convenient since it won. I thought it was the only nominee that felt in the class of stories I would expect to win a Hugo. I think this story needs one important caveat up front. The key conceit of the story is that, in this world, water falls on you out of nowhere if you tell any sort of lie. It does not explore the practical impact on that concept for the broader world. That didn't bother me; for some reason, I wasn't really expecting it to do so. But it did bother several other people I've seen comment on this story. They were quite frustrated that the idea was used primarily to shape a personal and family emotional dilemma, not to explore the impact on the world. So, go into this with the right expectations: if you want world-building or deep exploration of a change in physical laws, you will want a different story. This story, instead, is a beautiful gem about honesty in relationships, about communication about very hard things and very emotional things, about coming out, about trusting people, and about understanding people. I thought it was beautiful. If you read Captain Awkward, or other discussion of how to deal with difficult families and the damage they cause to relationships, seek this one out. It surprised me, and delighted me, and made me cry in places, and I loved the ending. It's more fantasy than science fiction, and it uses the conceit as a trigger for a story about people instead of a story about worlds and technology, but I'm still very happy to see it win.

Russ Allbery: Review: Ancillary Justice

Review: Ancillary Justice, by Ann Leckie
Series: Imperial Radch #1
Publisher: Orbit
Copyright: 2013
ISBN: 0-316-24662-X
Format: Trade paperback
Pages: 416
As Ancillary Justice opens, Breq is on an icy planet trying to track down a person who has gone rather thoroughly to ground. As her search continues, the reader slowly learns the context of that search, which is only the latest step of a long and quixotic exercise in private determination. She was set on her path by events twenty years previous, told in interleaved flashbacks, that have left her greatly diminished and thrust outside of any of the context of her over thousand years of life. Breq was Justice of Toren, a starship and AI that possessed thousands of ancillaries, human bodies slaved to her mind. Now only this one remains, and nothing exists of her former life other than this goal. It's always hard to write a review of a book that I loved this much. I want to find some way to grab the reader and shake them and say "you have to read this!" without giving away any of the delicious details. That's particularly difficult with Ancillary Justice, since one of the delights of this book is the slow unfolding of not only the plot but the background and motivations behind the plot. There is so much beneath the surface of Breq's methodical intent, and discovering all the nuances is utterly delightful. This is also a book that is very deeply concerned with identity, and which does one of the best jobs I've seen in science fiction of showing a non-human first-person protagonist: close enough to human to permit identification and comprehension, but far enough away for delightful sparks of unexpected insight or thought-provoking difference. Breq is a ship, and AIs are central to this story, so the comparison that comes immediately to mind is with Iain M. Banks. Leckie's role for ship AIs is much different than the structure of Banks's Culture, but I think this is still an apt comparison. Like Banks, Leckie is writing large-scale space opera dominated by a meddling empire that follows some familiar human patterns but not others. Banks's Culture takes a less direct approach with its meddling; the Radch has a more Roman attitude towards preventative conquest and citizenship. But both deal with large-scale issues of politics, culture, and conquest. Both also write excellent AIs, but I think Leckie is more successful than Banks at giving her AIs inhuman properties and creating a sense of eerie alienness that sometimes fades almost entirely and sometimes comes sharply to the surface. The first-person perspective helps considerably there. But where Ancillary Justice truly shined for me is in the interpersonal relationships, and in the insight they provided into character and motive. At the start of the book, Breq finds a drug addict dying in the cold and rescues her, bringing her along on her search for lack of a better option. Breq's relationship with Seivarden is complex, difficult for both of them, badly asymmetric at the start, and develops into something brilliant. At the start of the book, Seivarden is easy to dislike, and Breq's tone is refreshingly bracing and forthright. But through the course of the book Seivarden grows into something much more, in a way that I found both believable and incredibly compelling. And Leckie does this without falling into any of the typical relationship patterns, without introducing artificial romance (or, indeed, any romance at all, which is an excellent choice here), and without compromising the personalities of either character. It's masterfully done. One of the most amazing things about this book to me is that it's a first novel. I never would have guessed that from reading it. It's beautifully paced, the characterization is deep and compelling, and Leckie avoids any sign of the typical first-novel problem of stuffing the book with too much Stuff. Ancillary Justice is a capable and confident novel that builds a compelling world and even more compelling characters. I liked it more than I like most of the Culture novels, which is saying quite a lot, but Leckie offers much of the same scope with deeper and more personal characterization and a tighter plot. I haven't yet remarked on one aspect of this book that every other review seems to remark on: its treatment of gender. The Radch do not recognize or care about gender distinctions, and therefore Breq struggles throughout the book with proper gender labeling in much the same way that a native English speaker tends to struggle with grammatical gender when learning a Romance language, except with more social consequences. Leckie has chosen to represent this in the novel by having Breq refer to everyone uniformly as "she." This has its pluses and minuses: it still supports a binary gender concept where a gender-neutral pronoun might not, but given all the negative reaction this book got just for using "she," a gender-neutral pronoun might be a bridge too far for a lot of readers. I thought it created a nice bit of alienation, a way of forcing the reader to look at gender markers from the outside and a way to point out how arbitrary many of them are. It was also interesting to see how surprised I was at various points in the book when it became obvious that some person Breq had been calling "she" in the first-person narration turned out, from story context, to probably be male. That said, I think this part of the book is overblown in reviews. It's often the first thing people mention, but while it was a nice side bit of world-building, I don't think it's that central to the story. I'm particularly baffled by the handful of people who complained about it, since it's not intrusive and it quickly fades into the background apart from occasional necessary shifts of mental image. (It does create the impression of a world containing only women, but I found that a nice change from the more common impression in space opera of a world containing only men.) Ancillary Justice has already won the Nebula and Arthur C. Clarke awards and tied for the BSFA award for best novel, and I'm happy to report that it deserves all of those. I haven't yet read all of the other Hugo nominees, but it's hard to imagine a world in which it won't top my ballot. This is a fantastic novel, by far the best thing I've read so far this year. I'm delighted that it's the first book of a trilogy, since I'm not done with either the world or the characters yet, but it stands well on its own and reaches a satisfying conclusion. I recommend it to everyone, but particularly to anyone who likes Banks, intelligent ships, or who is looking for thoughtful and complex space opera. Followed by Ancillary Sword. Rating: 10 out of 10

Russ Allbery: Spring haul post

Sorry about the lack of posting recently. Work has been rather problematic, and also very distracting, and on my time away from work I've been relaxing rather than writing. Didn't even get reviews written while on vacation. I am still hoping to catch up on reviews, however. In the meantime, I have been reading some, and buying more books. Here's a new haul list. Elizabeth Bear Steles of the Sky (sff)
Katherine Boo Behind the Beautiful Forevers (non-fiction)
John Chu The Water That Falls on You from Nowhere (sff)
Lewis Dartnell The Knowledge (non-fiction)
David Lochbaum, et al. Fukushima (non-fiction)
Ben Goldacre Bad Pharma (non-fiction)
Mira Grant Parasite (sff)
Thomas Olde Heuvelt The Ink Readers of Doi Saket (sff)
Mary Robinette Kowal The Lady Astronaut of Mars (sff)
Madeline Miller The Song of Achilles (historical)
Edmund S. Morgan American Slavery, American Freedom (non-fiction)
Richard Rhodes The Making of the Atomic Bomb (non-fiction)
Lee Smolin The Trouble with Physics (non-fiction)
Charles Stross Equoid (sff)
Charles Stross Neptune's Brood (sff) This is a bit of a grab-bag, including a variety of non-fiction that I had recommended to me by various people. I also picked up the remaining Hugo nominees for best novel that won't be in the voter packet, and the short fiction from Tor.com that was nominated and was available for free from Amazon for the Kindle. I read The Knowledge while I was on vacation, and it's in my large backlog of pending reviews.

Gunnar Wolf: Meeting with Chilean sysadmins

Meeting with Chilean sysadmins
Ok, so I'm back in Mexico! This year, the best fare I found for travelling to spend the Winter^WSummer season with Regina's family had an oddity: I usually have a layover at either Santiago de Chile or Lima (Per ) of between 45 minutes and 2 hours, clearly less than enough to do anything. But this time, I had a massive 10 hours layover in Santiago. And spending 10 hours in an airport is far from fun. Specially when you have a good group of friends in town! I visited Chile in 2004 for Encuentro Linux (still before the time I had a digital camera: Those photos are all taken by Martin Michlmayr), and I have stayed in touch with a group of systems administrators since then. So, I mailed the list, and we managed to get eight people to have lunch together. In the order we appear in the photo: Some of them, even living in the same city, had never met in person before So, of course, we had a table reserved at the restaurant to the name of Dennis Ritchie. And having had nice, fun, sometimes-technical talks... Well, a tiny bit of his spirit was there. Of course, we can only trust he was there, as no Ouija boards were used and no null pointers were dereferenced (just to make sure not to disturb him). Victor Hugo and lvaro took me for a short Santiago city trip before lunch, we had a very nice time. Thanks! :-)
