Daniel Kahn Gillmor has a very good blog post. You should read it. It includes a thoughtful rebuttal to some of my earlier thoughts about activism. I think I'm developing a richer understanding of where I see boundaries here, but after my last post, I also realized that by focusing on the specific details of what should have been a minor alleged crime, I'm derailing. Swartz did so much else. I made a note to come back to the more theoretical discussion in six months; now isn't the time. Now is the time to celebrate open content and all of the things Swartz achieved. (But thank you very much to the multiple people who have pointed out flaws in my reasoning and attempted approach.) Hopefully, it's also an opportunity to keep the pressure on for a saner and less abusive judicial system that doesn't threaten people with ridiculous and disproportional punishment in order to terrify them into unwarranted plea bargains. The petition I mentioned has reached nearly 40,000 signatures and passed the threshold (at the time it was posted) for forcing a White House response. Probably more importantly, it also seems to be creating the feedback cycle that I was hoping to see: the popularity of the petition is causing this story to stay in the news cycle and continue to be written about, which in turn drives more signatures to the petition. I'm not particularly hopeful that the Obama administration cares about the vast and deep problems with our criminal justice system, but I'm somewhat more hopeful that they, like most politicians, hate news cycles that they don't control. The longer this goes on, the stronger the incentive to find some way to make it go away, which could lead to real disciplinary action. A key committee in the US House of Representatives is starting a formal investigation. One of my local representatives has proposed modifying the US federal law on computer fraud and abuse to remove violations of terms of service from the definition of the crime. (I don't have much hope that this will pass when proposed by the minority party in a fairly hostile House, but the mere act of proposing it keeps the news focus on.) Glenn Greenwald has a (typically long-winded) round-up of news in the Guardian. Note that both Greenwald and Declan McCullagh link directly to the petition in articles in mainstream news outlets. One thing that slacktivism can do is perpetuate a news cycle until it gets more uncomfortable for people in power. It's still nowhere near as effective as the types of activism that Swartz was so good at, but in this specific case I think one gets a reasonable return on one's five-minute investment of effort. I'm going to stop talking about this now, since other people are a lot better at this sort of post than I am. But one last link: the medical community has a related open content problem, and theirs is also killing people. Possibly people you know. If all of this has inspired you, as it has me, to care even more about open content, be watching the push for open access to clinical trial data. More background is in Ben Goldacre's TED talk.

release is the tool that I use to manage software releases. This version adds support for signing a tarball with multiple PGP keys at once. For WebAuth, we have an official signing key, but I also wanted to add my personal signature. The minimum supported version of Python was also bumped to 2.5 (see below for why). You can get the latest version from my scripts page. Normally, I wouldn't announce this to everyone, since it's a fairly minor change, except I had a question and a quick Python note. The question: how does one get GnuPG to verify multiple signatures? When I run GnuPG on the resulting detached *.asc file created by this new code, I get the following:

gpg: WARNING: multiple signatures detected.  Only the first will be checked.
gpg: Signature made Thu 10 Jan 2013 03:58:43 PM PST using RSA key ID 5736DE75
gpg: Good signature from "Russ Allbery <rra@stanford.edu>"
gpg:                 aka "Russ Allbery <rra@debian.org>"
gpg:                 aka "Russ Allbery <eagle@windlord.stanford.edu>"
gpg:                 aka "Russ Allbery <eagle@eyrie.org>"

That's nice, I suppose, but it's not as helpful as it could be. Why not verify both signatures and report all of the results? I searched both the gpg man page and the Internet for some option I'm missing, without any luck. (Searching Google for that exact message amusingly turns up lots of verbatim output from Debian repository verification and almost nothing else.) If anyone knows, send me email (rra@stanford.edu or any other convenient address), and I'll update this post with the answer. UPDATE: gpg can currently only verify multiple signatures if the signatures are from keys with the same class and digest. I was attempting this with a 2048-bit RSA key and a 1024-bit DSA key, which gpg does not support. (Yet another reason to replace the WebAuth signing key with a newly-generated key.) Thanks to Philip Martin and Bernhard R. Link for the information! The note is that, way back when I was first learning Python, one of the things that bothered me the most was the lack of safe program execution. The best available was os.spawnv(), which left something to be desired. If you too were bothered by this but don't program in Python enough to keep track of the current state of the art, there's now a subprocess module that has much saner interfaces that work properly, do reasonable things, and avoid the shell. It was added in Python 2.4, with some nicer interfaces added in Python 2.5, so it's fairly safe to use at this point.

Janis Voigtl nder has invited me again to give a lecture in his Advanced Functional Programming course at the University of Bonn. Like last time, when I talked about performance analysis in Haskell, I chose a topic that is more on implementationishy side to contrast the theoretic content of the rest of the course. I recycled my talk on the memory representation of GHC that I have held at last year s Meta Main-Rhein Chaos Days. As usual I provide a transcript of the talk as intended (not as held). It is slightly revised over the old version and I have added a section on unboxed values in constructors, which I have nevertheless skipped today.

As there is still some development ongoing in Weblate, it's time to share information about some of the features you can expect in upcoming release. Recently, Weblate gained ability to display changes which caused string to be fuzzy. This currently only works with Gettext PO files as no other format provides this information. If this is available Weblate shows differences between current and previous string, what allows translator to easily spot what has been changed. Example can be seen on Uzbek translation of phpMyAdmin (until somebody translates that). While working on this feature, I've realized, that Django does not include this information in PO files. Fortunately it was pretty easy to fix and I've created a pull request to implement this. Looking at this file made me fix another thing which annoyed me since I've used translations in Django for first time - it generates POT file for every language, making the updates really slow. Fortunately it was also easy to fix and pull request is here. So if you feel makemessages is too slow, this is patch for you. But back to Weblate as there are more changes. For example automatic locking now works more fine grained and uses AJAX to update lock period. This means translation will be unlocked much faster if you close browser with Weblate. Also searching for messages has been updated to include substring search as well as it is sometimes more useful than fulltext search.

Earlier this morning, JJ announced what we had been working on for the last few weeks: the Rcpp Gallery. Now, as our luck will have it, the Rcpp-devel list received his message but did not transmit it for an apparent mail system outage at WU Vienna: no sign at the Gmane archive of rcpp-devel or in the personal mailboxen of myself or anybody I spoke to. Hence, so far, and preceding this blog announcement, the only way word got out was via this earlier tweet of mine from about 12 hours ago. The Rcpp Gallery is really the brainchild of JJ. It builds on what he contributed over the last few months in not one but two implementations: Rcpp Attributes. These are described in a vignette of their own. They provide very powerful new functions like sourceCpp which allow the easiest-yet way to get compiled code into R---see for example these posts from my blog about simulating pi in essentially five lines of R or five lines of C++, or this post about using the GSL with ease from R. The Rcpp Gallery also builds on Yihui's excellent knitr package which gained the ability to process C++ code just like R code, as well as some Ruby / Jekyll magic to build a website on the github infrastructure. I helped a little on the side by (at long last) learning how to do prettier websites thanks to Boostrap and its theming extensions. So what does it do, and what is it for? Have a look around the Rcpp Gallery site. Each post is based on a single C++ (or Markdown) file which gets digested by knitr and Rcpp, with the actual output shown alongside the marked up code and explanatory text. Raw sources are available, just pass them into the sourceCpp() function from a current Rcpp release and you should have the same output. Our idea is to have this as a repository for useful code: from simple and introductory to fancy and featureful. We already seeded it with several dozen posts covered anything from lesser known but powerful STL idioms, to Rcpp sugar, to tieing in Armadillo or GSL, random number generation and of course benchmarking---as we do love performance. The entire content is in this github repository, and our page on how to contribute details how you can get involved. We are looking forward to what is to come. In many ways, we are only just getting started.

This is my monthly summary of my free software related activities. If you re among the people who made a donation to support my work (836.78 , thanks everybody!), then you can learn how I spent your money. Otherwise it s just an interesting status update on my various projects. Debian Packaging I uploaded Zim 0.58, WordPress 3.5 (and I had to file a ticket about the availability of sources of minified javascript files again) and another security update for python-django (696535). Speaking of python-django, I forwarded one bug report of Anders Kaseorg concerning Django s bash completion (#695811). I also sponsored the upload of ledgersmb 1.3.25-1. Other Debian work I contributed some patches to improve debian-installer support in live-build. I also added a work-around for bug #652946 in live-installer and committed a fix for this same bug in a jessie branch of partman-target. I also prepared a bugfix for a counter-productive behavior of choose-mirror (#695261, it was not possible to override the codename of the release to install via preseed if you install from a CD with a full base system). I discovered an oddity in the Packages.diff/Index file for the architectures armhf and s390x, I reported it to ftpmasters in #696792. (All those issues were discovered while working for a customer) Debian France I spent quite some time on Debian France this month again. I started by setting up an internal gitolite to manage our accounting/administrative documents. Then I updated galette, the web application that we are using to manage our database of members. In the process, I filed two bugs that we discovered. I immediately tested Galette by registering 4 members that joined during the former mini-Debconf in Paris. We have plans to automate the membership renewal process so we have opened a Paypal account. This month we also cleared the last steps so that I and Sylvestre Ledru have full control on the Debian France bank account. I also registered the new officers at the Tribunal d instance de Sarreguemines . Salt bug reports During the last mini-debconf, I discovered Salt (thanks to Julien Cristau!) and since I had to switch some servers of mine, I took this opportunity to upgrade to wheezy and try out salt at the same time. It took much more time than expected but the result is pleasant. The configuration of all my servers is now well documented/specified in a central Git repository, and moving services is much easier than before. In the process, I filed quite some bugs (#2865, #2851, #2866 and #2875), most of them have been fixed in the 0.11.1 release that just happened. Thanks I wish you a happy new year and all the best for 2013! See you next month for a new summary of my activities.

This issue is about a bit specific situation in Germany and it's (mainly tax-financed) public service broadcasting. If you think you are not interested, please skip this entry. :) Just beginning from scratch... In Germany we have (like most european countries) a public service broadcasting. Starting with 2013 the system collecting the funding of the public service broadcasting changed from GEZ to Beitragsservice.
To make it short (and a bit simplified) ... it changed from "most 'families' have to pay" to "every menage has to pay". This means, even if you don't have any device to use the service of the german public service broadcasting but are a menage, you have to pay for it. This sitiation is even more worse than pay-TV. Don't get me wrong ... I'm neither against public service broadcasting nor against paying for it in principle. In the rare cases I'm watching TV, this is most likely a channel of the public service broadcasting. Same counts for the rest of my small family. Mostly we are watching news and documentations ... also some movies are watched. The kids are watching KiKA, which we like cause it's Ads-free and it's not just some cartoons with hidden violence. So we most likely benefit from public service broadcasting. Anyways ... in common we are not using "TV" as most of the others may do. We still like some sort of the broadcast, but we are missing it cause various reasons. For our luck there is a service called 'Mediathek' provided by the most german public service broadcasting channels. If you missed a broadcast or are prevented for any reason, you may watch the broadcast there. Unfortunately the timeframe you can access the broadcast is very short, in most cases 7 days. This is manifested in the so called Rundfunkstaatsvertrag, more precisely in the 12. Rundfunk nderungsstaatsvertrag. The 'Tagesschau' has a good explanation about the issue. This means, in simple words, the tax payed broadcasts needs to be deleted after a (in my eyes) short time. WTF?!? Why do we wipe work we all payed for it? Guess what ... it was implemented by lobbying from commercial print media and private (e.g. ads-financed) TV-channels. A comment about a related problem, which I agree, can be found here. Another challenge ... How do you know there is a broadcasting your are interested in? How do you know when it is broadcasted? I remember, my parents was subscribed to a daily newspaper, which included an additional TV paper, my parents-in-law bought also one.
As we are neither subscribed to a daily newspaper nor buying a TV paper, we have to solve that differently (beside that a printed paper won't help us I think). When we use the opportunity to watch TV at the evening, I just use an electronical TV paper (-app). If we find something which fits, we are fine .. if not, we do other things. This sounds a bit like an old school behaviour and it is not, how I would like to use a media today. I like using a feedreader. You can subscribe differnt 'channels' of information feeds and it is a way I would love to use TV. In the past I used a tool called 'Mediathek', which is a tool for Mac OSX. With this tool it was easily possible to find broadcasts, you could subscribe to so called 'channels', which means broadcasts of a same series for example. You could also mark them as "unread" und "read" .. something like a feedreader.
On the other way, it was also possible to list recent broadcast per genres and popular broadcast of the recent and the last week. This was very comfortable as this was working for several mediathek sites for german public service broadcasting channels in one central place. For every broadcast you could just view it or download it to view it later. You could even download subscribed channels automatically. After using the Mediathek-App and being satisfied by the Mediathek sites of the german public service broadcasting channels for several years, this week the server(s) behind the App was shut down. What the f....?!? On Twitter the author stated that the shutdown was cause by problems with the copyright law. Das Erste, ZDF and WDR denied that they has anything todo with this recent issue. The question is ... what is the direct cause for shutting down such a good service. This smells a bit like the PirateBay issue, but in this case the content which is Mediathek providing access to isn't pirated, but legal hosted. So where is the real issue? In my mind, the german citizen has payed to produce this content and should have the right to access the content is an usable way. The Mediathek App did provide such a way and it is really pissing me off that this access isn't available anymore, at least for this reason. Actually I don't see any solution to access our payed content in a decent way. Footnote: I think it's obscenely, that publishing houses and commercial broadcaster trying to gain their turnover at the expense of the german citizen by forcing the german legislature to implement Depublication,.

You may have noticed that I recently started posting more updates again. The reason is, I switched over from Wordpress to Octopress as blogging engine. The idea was driven, cause my used theme K2 got stuck and with the upcoming release of Debian wheezy I'm forced to switch to a more recent Wordpress release, which is likely incompatible.
Another reason is, that I got bored by wordpress itself (and it's software dependencies). With octopress these dependencies are lowered to a webserver which can server static files and rsync on the server side. Maybe I will post some parts of the story, what I did when migrating the content and what components (plugins, theme ...) I'm using, later.

AreWomenHuman has an interesting article about ViolentAcrez and the wide support for trolling (including by media corporations) [1]. Chrys Stevenson wrote an important article for the ABC about the fundamentalist Christians who are trying to take over the Australian education system [2]. Tavi Gevinson gave an interesting TED talk titled A teen just trying to figure it out about her work starting Rookie magazine and her ideas about feminism [3]. Burt Rutan gave an interesting and inspiring TED talk about the future of space expploration [4]. One of his interesting points is that fun really is defendable in regard to tourism paying for the development of other space industries. Stephen Petranek gave an interesting TED talk about how to prepare for some disasters that could kill a significant portion of the world s population [5]. Some of these are risks of human extinction, we really need to spend some money on it. John Wilbanks gave an intresting TED talk about the way that current informed consent laws prevent large-scale medical research [6]. He says I live in a web world where when you share things beautiful stuff happens, not bad stuff . Joey Hess was interviewed for The Setup and the interview sparked a very interesting Hacker News discussion about workflow for software development [7]. Like most developers I prefer large screens with high resolution, I have an EeePC 701 which works reasonably well for an ultra-portable system but I largely don t use it now I have an Android phone (extremely portable and totally awful input usually beats moderately portable and mostly awful input for me). But Joey s methods are interesting and it seems that for some people different systems give the best result. Jeff Masters gave an insightful TED talk about the weather disasters that may seriously impact the US in the next 30 years [8]. Governments really need to start preparing for such things, some of them are really cheap to mitigate if work is started early. Bryan Stevenson gave an inspiring TED talk about the lack of justice in the US justice system [9]. Wouter Verhelst wrote an insightful article about some of the criticisms of Linux from Windows users [10]. He references a slightly satirical post he previously wrote about why Windows isn t ready for desktop use. Paul Carr wrote an interesting article comparing disruptive business practices of dot-com companies to the more extreme aspects of Ayn Rand s doctrine [11]. In reading some of the links from that article I discovered that Ayn Rand was even more of a sociopath than I had previously realised. Lindy West gave an amazing Back Fence PDX talk about dealing with nasty blog comments from the PUA/MRA communities [12]. After investigating them she just feels sorry for the trolls who s lives suck. Hang from the Vlogbrothers explains gender, sex, sexual orientation, etc [13]. Rick Falkvinge wrote an interesting article about recent political news from Brazil, they had a proposed law that was very positive for liberty on the Internet but it was sabotaged by the media and telcos [14]. We should try to avoid paying any money to the media industry so that they can go away sooner. Amy Cuddy gave an interesting TED talk about body language, power, and the imposter syndrome [15]. Caleb Chung gave an interesting TED talk about toy design which focussed on Pleo a robotic dinosaur with a SD card and USB socket to allow easy reprogramming by the user [16].

In 2011, I wrote about how small files could consume a lot of space. I meant to do a follow-up on the savings but I forgot about it until now. In 2.5.7, we started compressing some of the collected data files. Some of these are ridiculously compressable (#664794). Even better, compressing them is sometimes faster than writing them directly to the disk, so in some cases it is a pure win/win. For lintian.d.o, we also see a vast size reduction in overall size of the laboratory. I have taken a few samples occasionally. The samples were done with du(1):
$ du -csh [--apparent-size] laboratory/*


Version/date	du -csh	apparent-size
N/A around 20 Mar 2012 (#664794)	16G	13G
2.5.6 (Fri Apr 27 2012)	14GB	N/A
2.5.6 (Mon Jun 04 2012))	N/A	12G
2.5.10.2 (Fri Sep 21 2012)	12G	8.3G
2.5.11 (Wed Jan 2 2013)	10G	6.1G

And the most awesome part of this? The comparison is quite biased against the 2.5.11 entry, which is the only entry to also process experimental (approx. 10% extra packages). Some of the early entries (2.5.6 and older ) might also have suffered from the too many links issue[1]. I only wish I had been better at collecting data points, so I could have made a proper graph of it. It sounds almost too good to be true, but if you look at the size of one of the linux-image packages[1], the space usage dropped from 27M to 15M between 2.5.5 to 2.5.9. Currently it is squeezed down to 14M (tested with head of the git master branch). [1] I believe is about 5-10% less binary packages processed for those runs. [2] linux-image-3.2.0-2-amd64_3.2.20-1_amd64.deb

Yet another yearly summary of my running activities. It seems, indeed, that running has now slightly taken precedence over free software activities in my life and priorities for my free time. To my fellow free software friends: don't worry, I'm not on my way to stop investing my time in Debian. It's quite clear that I'm reducing my involvement, mostly because days only have 24 hours...not because I'm bored or tired by free software development. But, certainly, it became an important thing that running currently has a small priority over Debian nowadays, for me. So, what happened on that front in 2012 for running bubulle? I finally managed to run 2900 km during the year, which is over 400km more than 2011. This is mostly due to the increasing part of running in my daily commute : a typical work week can now be something like this:

• Monday morning, leave home with a big bag and clothes for up to 4 work days (including those I'm wearing) plus running clothes (and shoes).
• Monday evening: come back by running. Either 4km, then 30 minutes train ride, then 3km more....or "the long version": 10km, then 20 minutes train ride, then 3km more.
• Tuesday: go to work by run+train+run, shower, change clothes, work, come back by run+train+run
• Wednesday: ditto
• Thursday: let's have a break. I usually work in another facility where it's less convenient to go by running
• Friday morning: go to work by run+train+run
• Friday evening: come back home with a big bag of dirty clothes

With such an organization, I can end up with weeks where I run up to 50-60 kilometers in 5 days, with peaks that may include 26km in one *work* day. I also end up having room in trains between the runs, I wonder why..:-) And, of course, during week-ends, I spend some parts of my time running too..:-). Indeed, just like for many drugs, I feel sad during days where I haven't run at all and it's usually hard for me to spend more than 2 days without. Indeed, the longest time period without running, this year, has been 9 days, just after the Caen marathon, in June. Mostly because, at that time, I reached a moment where training (and believe me, very boring and hard training) consumed all my motivation. But these moments are indeed very rare and training is mostly *never* boring for me. Mostly because I like running in the nature, in forests, woods, fields, country. Never wearing an MP3 player or any kind of such device toplay music, but just enjoying the outside, whether it's raining, winding, sunny hot. Running (particularly my daily commute) is also the moment where I *think* about my work, my technical activities, my own life, whatever. I think I even sometimes translated some software, mentally, while running..:) Indeed, there have been 205 days in this year where I ran at least once. Last year was 181 so....drug addiction is increasing. So, 2900 kilometers. That's about the distance from my place to Moscow in Russia. 282 hours (11 days18 hours.....9d21h last year). Average speed: 10,3km/h (10,5km/h last year). Cumulated height difference: 33,400 meters (27700m last year). More distance, more time, a bit slower: this is an obvious consequence of more trail running (which includes more difficulties, such as running on volcanoes!). Most active month: November with 331km. Less active month: June with 141km. This year was also a year of records:

• personal best broken in September by....14 seconds....on half-marathon with 1h37'28" after failing a first time by 20 seconds in March
• personal best broken twice in the two marathons I ran. first in June, in Caen, after a very hard 8-week training and in difficult conditions (rain, wind, hard race profile) with 3h38'45". Then, I managed to run a stunning 3h33'35" in October in Val du Rueil (a small town in the Seine river valley). That one will be hard to break now.
• longest distance run, with the "80km" Paris Ecotrail run in March, in 11 hours
• great progress in my other "ultra" race (70km in November) which I ran in 8h22 instead of 9h15 last year

I ran 10 official races during the year : two "ultra" races (70km Le Puy-Firminy in November, by night and 80km Paris Ecotrail in March), two marathons (Caen and Val de Rueil), four half-marathons and two "short" (less than 30km) trail races. How about next^W this year? Well, my goals are currently being secured:

• more trail races than roads races
• Paris 80km Ecotrail again in March. Goal: beat last year's 11 hours
• Le Puy-Firminy 70km again in November. A very nice "small" race (small by number of participants....but the effort is not small!).
• Mont-Blanc "marathon" in late June. Indeed a 42km trail race in Chamonix, starting at 1000m, finishing at 1600m, with a peak at 2300m and 2500m positive vertical gain (1490m negative).
• Another "long" trail race (40-60km) somewhere in April/May
• A "classic" marathon in October/November. Probably somewhere in France. Maybe La Rochelle. That might be the only classic marathon I run this year...unless I decide for another challenge like running two marathons in two consecutive Sundays..:-)
• Do once again my own personal marathon which is just "come back from work by foot".....which nearly equals the distance of a marathon. Something I achieved for the first time in September, in about 5 hours
• Maybe try a 6 or 12 hour race (running for 6 or 12 hours...or more...on a small 1-2km loop). These ones are very friendly ones and the only races where lame runners like me can run along with the best ones, not only for the first 100 meters.

All this of course is assuming that no injury comes up (my ankles are sometimes yelling outbut I'm fortunate enough to not have articulation problems that many runners have, particularly in knees). We'll see on January 1st 2014...:-)

Review: City of Diamond, by Jane Emerson

Publisher:	DAW
Copyright:	March 1996
ISBN:	0-88677-704-6
Format:	Mass market
Pages:	624

The setting is deep into the star-faring future of humanity. Humans have settled many other worlds, thanks largely to technology from a race named the Curosa. There is a thriving network of settlement based around a sort of warp conduit network. But, standing apart from most human settlements, are three huge ships: the City of Opal, the City of Pearl, and the City of Diamond. Their inhabitants are devout members of the Redemptionist faith, a merging of Christian (primarily Catholic) belief and Curosa religion. Their ships are gifts from the now-departed Curosa, featuring drives unknown to the rest of humanity that allows them to ignore the normal transport network. They are meant to witness and spread their religion, but now, six centuries later, they primarily trade. Much of this is not apparent at the start. City of Diamond opens with Adrian Mercati, chosen heir of the current dying Protector, dodging people in what seems to be an oddly-organized city. Impudent, occasionally flippant, utterly charming, and in love with danger, he inherits the position of Protector shortly after we meet him. Emerson slowly reveals more of the nature of the ship while Adrian is shocking (and charming) the nobility and the church, and consorting with demons. Or, at least, one demon: Tal, an entirely human-appearing creature except for his eyes, who the Redemptionists claim is born without a soul. Slowly, it becomes clear that he's actually the offspring of an alien and a human, a mating of species whose children cannot socialize as human and behave in ways that seem like human sociopaths. Tal is no exception, but his interests align with Adrian's for the time. To those two viewpoint characters, Emerson adds four more: a low-rank administrator named Spider who works for Tal after Tal saved him from death by recycling, Adrian's politically-arranged bride-to-be from the rival (and even more religious) ship City of Opal, a guard from a French-descended slum on City of Opal, and a dangerously honorable and literal mercenary from an off-shoot culture of humanity that's now only a legend. This is a book that tends to sprawl. There's quite a lot going on, starting with the negotiations between City of Diamond and City of Opal to put to rest the remnants of a civil war and leading to the search for a legendary Curosa artifact on the planet they're both visiting. All of the characters have their own agendas, their own history, and their own goals, and are pursuing them in parallel and occasionally in opposition. Emerson takes the time to let all of this build. Despite that, there is very little in this book that drags or bores, and that's due primarily to the strength of the characters. Every one of the viewpoint characters is unique, bringing a different perspective to the story, and every one of them changes and grow over the course of the story. They also play off of each other in delightful ways. This is a book that makes full use of the fact that three characters make seven character interactions. For example, Tal by himself is logical but just slightly askew, Tal seen by Spider is uncomfortable and worrisome, Tal and Adrian is a dance of mutual amusement and respect, and Tal and Keylinn finding points of commonality is just delightful. I did wish that there was a bit more Keylinn and Tal and a bit less of Spider, but once Emerson built her world, introduced her characters, and got the story moving, there aren't many weak pieces. Part of the fun is figuring out the world background. There are almost no infodumps here; Emerson just starts telling stories of characters in the surroundings in which they find themselves, and the reader is left to piece things together from background description, the occasional explanation from one character to another, and parallels with long-standing SF tropes. It's not a puzzle book, but it is a book of where the reader is dropped as an alien into a fully-developed culture. In both that way and in the use of nobility, religion, and formal hierarchy against a starfaring backdrop, City of Diamond reminds me of the sort of classic space opera that led up to Star Wars but isn't seen as much these days. It's also funny. I was unsurprised to discover that Emerson is a pseudonym for Doris Egan, who (in addition to writing some other SF) is an occasional writer and producer for House. The humor isn't entirely obvious at the start, although Adrian frequently provokes a grin from the start of the book, but Tal's perceptive but obliviously blunt comments become more and more fun as the book progresses, and both Iolanthe (Adrian's bride) and Keylinn (the mercenary, sort of) are a delight. I want to see more of both of them, but sadly the book ends just as they (particularly Iolanthe) are hitting their strides. And that's the biggest problem with City of Diamond: it's a failed (or at least postponed) trilogy. As with Walter Jon Williams's Metropolitan and City on Fire, there were supposed to be more books, but apparently either the publisher lost interest or other projects took precedence. The story does come to something of a conclusion, but most of the major story arcs aren't resolved. Emerson is still bringing more guns onto the set late in the book. None of the villains truly get their just desserts, nor do most of the character arcs fully resolve, although friendships and more have formed satisfyingly by the end of the book. There is obviously far more to both these characters and this universe, including an entire ship that was never visited and an alien whose presence should prove startling. This is a great book: warm, funny, full of interesting characters, and with a nicely complex background universe. If it were complete in itself, or if the sequels had materialized, I would recommend it unreservedly. As is, you will have to weigh your dislike of unfinished stories against its stand-alone merits. But I enjoyed it a great deal. Rating: 7 out of 10

mksh made quite some waves (machine translation of the third article) recently. Let s state it s not just Amigas ara5 is a buildd running the Atari kernel, an emulated though. On the other hand, the bare-metal Ataris used to be the fastest buildds, so I expect we get them back online soonish. I m currently fighting with some buildd software bugfixes, but once they re in, we will make more of them. Oh, and porterboxen! Does anyone want to host a VM with a porterbox? Requirements: wheezy host system (can be emulated), 1 GiB RAM, one CPU core with about 6500 BogoMIPS or more (so the emulated system has decent speed; an AMD Phenom II X4 3.2 GHz does just fine). Oh, and mksh is ported to more and more platforms, like 386BSD 0.0 with GCC 1.39, and QNX 4 with Watcom and more bugfixes are also being worked on. And let s not forget features! jupp got refreshed: it s got a bracketed paste mode, which is even auto-enabled on xterm-xfree86 (though the xterm(1) in MirBSD s a tad too old to know it; will update that later, just imported sendmail(8) 8.14.6 and lynx(1) 2.8.8dev.15 into base, more to come) and will be enhanced later (should disable auto-indent, wordwrap, status line updates, and possibly more), lots of new functions and bindings, now uses mkstemp(3) to create backup files race-free, and more (read the NEWS file). In MirBSD, Benny and I just added a number of errnos, mostly for SUSv4 compliance and being able to compile more software from pkgsrc without needing to patch. This is being tested right now (although I should probably go out and watch fireworks in less than a half-hour), together with the new imports and the bunch of small fixes we accumulate (even though most development in MirBSD is currently in mksh(1) and similar doesn t mean that all is, or worse, we were dead, which we aren t). I ll publish a new snapshot some time in January. The Grml 2012.12 also contains a pretty up-to-date MirBSD, with a boot(8/i386)loader that now ignores GUID partition table entries when deciding what to use for the a slice. If you haven t already done so, read Benjamin Mako Hill s writings!

January Started cycling again. By the end of the year I had done 2,300 miles. (Strava profile) February Private concert at the British Museum of Haydn baryton trios for the annual winding of the Thomas Tompion Mostyn clock. March Zadok Baroque premiere concert, East Sheen. (review) April Belsize Baroque concert, Bloomsbury. May Lute concert, Greenwich. June Left Playfire. July/August YCombinator, California. September Renaissance viol weekend, West Sussex. October Moved house. November Battersea Park 5K. Ran 200 miles this year. December Beethoven Triple concerto, Cambridge. (more)

This year it turned out that we had to care the first time for ourself about Christmas dinner. So we decided to try a roast goose. Obtaining the goose is a different story and will maybe told later. The second challenge was to select a recipe. We found a great one at Die Rezeptesammlung der Unix-AG

In order to start the year in a good mood, what's the best than squashing some bugs on OpenStack? Therefore, the Ceilometer team is pleased to announce that it organizes a bug squashing day on the Friday 4th January 2013. We wrote an extensive page about how you can contribute to Ceilometer, from updating the documentation, to fixing bugs. There's a lot you can do. We've good support for Ceilometer built into Devstack, so installing a development platform is really easy. The main goal on this bug day will be put Ceilometer in the best possible shape before the grizzly-2 milestone arrives (10th January 2013). This version of Ceilometer will aim to keep compatibility with Folsom, so early deployers can enjoy some of our new features before upgrading to Grizzly. After that date, we'll start merging more extensive changes. We'll be hanging out on the #openstack-metering IRC channel on Freenode, as usual, so feel free to come by and join us!

Review: Regenesis, by C.J. Cherryh

Series:	Cyteen #2
Publisher:	DAW
Copyright:	January 2009
ISBN:	0-7564-0592-0
Format:	Mass market
Pages:	682

Regenesis is a direct sequel to Cyteen, picking up very shortly after the end of that book and featuring all of the same characters. It would be absolutely pointless to read this book without first reading Cyteen; all of the emotional resonance and world-building that make Regensis work are done there, and you will almost certainly know whether you want to read it after reading the first book. Besides, Cyteen is one of the best SF novels ever written and not the novel to skip. Because this is such a direct sequel, it's impossible to provide a good description of Regenesis without spoiling at least characters and general plot developments from Cyteen. So stop reading here if you've not yet read the previous book. I've had this book for a while, and re-read Cyteen in anticipation of reading it, but I've been nervous about it. One of the best parts of Cyteen is that Cherryh didn't belabor the ending, and I wasn't sure what part of the plot could be reasonably extended. Making me more nervous was the back-cover text that framed the novel as an investigation of who actually killed the first Ari, a question that was fairly firmly in the past by the end of Cyteen and that neither I nor the characters had much interest in answering. Cyteen was also a magical blend of sympathetic characters, taut tension, complex plotting, and wonderful catharsis, the sort of lightning in a bottle that can rarely be caught twice. I need not have worried. If someone had told me that Regenesis was another 700 pages of my favorite section of Cyteen, I would have been dubious. But that's exactly what it is. And the characters only care about Ari's murderer because it comes up, fairly late in the novel, as a clue in another problem. Ari, and Justin, are back in the safe laboratory environment of Reseune, safe now that politics are not trying to kill or control them. Yanni has taken over administration. There is a general truce, and even some deeper agreement. Everyone can take a breath and relax, albeit with the presence of Justin's father Jordan as an ongoing irritant and hostile factor. But broader Union politics are not as stable: there is an election in progress for the Defense councilor that may break the tenuous majority in favor of Reseune and the Science Directorate, Yanni is working out a compromise to gain more support by turning a terraforming project loose on a remote world, and Ari isn't sure she likes that Eversnow idea at all. Then, just as things seem to be turning Reseune's way, politics and interpersonal relationships abruptly deteriorate, tensions with Jordan sharply worsen, and there may be moles in Reseune's iron-clad security. Navigating the crisis while keeping her chosen family safe will once again tax all of Ari's abilities. The third section of Cyteen, where Ari finally has the tools to take fate into her own hands and starts playing everyone off against each other, is one of my favorite sections of any book. If it was yours as well, Regenesis is another 700 pages of exactly that. As an extension and revisiting, it does lose a bit of immediacy and surprise from the original, and Regenesis is much less concerned with the larger questions of azi society, the nature of thought and personality, loyalty and authority, and the best model for the development of human civilization. It's somewhat less far-thinking and more of a political thriller. But it's a political thriller that recaptures much of the drama and tension of Cyteen and is full of exceptionally smart and paranoid people thinking through all angles of a problem, working fast on their feet, and successfully navigating tricky and treacherous political landscapes. And, like Cyteen but unlike others of Cherryh's novels I've read, it's a novel about empowerment, about seizing control of one's surroundings and effectively using all of the capability and leverage at one's fingertips. That gives it a thrilling catharsis that's almost as good as Cyteen. It's also, like its predecessor, a surprisingly authoritarian novel. I think it's in that, more than anything else in these books, that one sees the impact of the azi. Regenesis makes it clear that the story is set, not in a typical society, but inside a sort of corporation, with an essentially hierarchical governance structure. There are other SF novels set within corporations (Solitaire comes to mind), but normally they follow peons or at best mid-level personnel or field agents, or otherwise take the viewpoint of the employees or the exploited. When they follow the corporate leaders, the focus usually isn't down inside the organization, but out into the world, with the corporation as silent resources on which the protagonist can draw. Regenesis is much more of a balance. It's about decisions of the future of humanity that characters feel they can make undemocratically (in part because they or their predecessors have effectively engineered the opinions of the democratic population), but it's also about how one manages a top-down organization. And, most vitally, how one secures it. Reseune is, as in the previous novel, a paranoid's suspicions come true; everyone is out to get everyone else, or at least might be, and the level of omnipresent security and threat forces a close parsing of alliances and motivations that elevates loyalty to the greatest virtue. In Cyteen, we had long enough with Ari to see the basic shape of her personality and her slight divergences from her predecessor, but her actions are mostly driven by necessity. Regenesis gives us more of a picture of what she's like when her actions aren't forced, and here I think Cherryh manages a masterpiece of subtle characterization. Ari has diverged substantially from her predecessor without necessarily realizing it, but in ways that are firmly grounded in the differences she found or created between her life and the first Ari's. Specifically, she has friends, confidents, and a community, which combined with past trauma has made her fiercely, powerfully protective, and it's that protective instinct that weaves the plot together. It's probably the most significant way in which so much of the events of Cyteen and Regenesis are driven by people's varying reactions to trauma. If you, like me, loved the last third of Cyteen, read this, because Regenesis is more of exactly that. Cherryh finds new politics, new challenges, and a new and original plot within the same world and with the same characters, but it has the same feel of maneuvering, analysis, and decisive action. You will, as with Cyteen have to be comfortable with pages of internal monologue from really smart people thinking through all sides of a problem. If you didn't like that in the previous book, avoid this one; if you loved it, here's the sequel you didn't know you were waiting for. Rating: 9 out of 10

Hang tight folks, this is a trippy one: As many have noted in my most recent post, I ve taken a shine to lisps hosted in Python. While clojure-py is badass, it s not fit for using from python. I hit some problems in the way it handles atomic variable access (well atomic , it s actually not ;) ), so I ve decided to give it a shot myself. That s right. I wrote a Lisp. A very basic, unmacroed lisp, but a lisp. So, let s take a look a trivial hy file pair The first file (really_lisp.hy), is as follows:

; vim: tabstop=2 expandtab shiftwidth=2 softtabstop=2 filetype=lisp
; Copyright (c) Paul Tagliamonte, in sofar as any of this is at all
;  copyrightable.
(def hello "World!")
(def square (fn [arg]
  (* arg arg)))
(def factorial (fn [n]
  (if (<= n 1)
   1
   (* n (factorial (- n 1))))))
(def fib (fn [n]
  (if (< n 2)
    n
    (+ (fib (- n 1)) (fib (- n 2))))))

And, the example Python script example.py is as follows:

import hy.lang.importer
import really_lisp
print really_lisp.hello
# "World!"
print really_lisp.square(4)
# 16
print really_lisp.factorial(10)
# 3628800
print [really_lisp.fib(x) for x in range(1, 20)]
# [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144,
#        233, 377, 610, 987, 1597, 2584, 4181]

Please note two awesome things firstly, we re importing a non-python script into a Python module. Awesome. Secondly, we re able to access symbols natively, as well as functions. Let s also demonstrate the other way (just hython this time):

; vim: tabstop=2 expandtab shiftwidth=2 softtabstop=2 filetype=lisp
; Copyright (c) Paul Tagliamonte, in sofar as any of this is at all
;  copyrightable.
(puts "Hello, World!")
; "Hello, World!"
(import ["os"
         "sys"])
(puts (os.path.abspath "."))
; "/home/tag/tmp"
(puts sys.argv)
; ['/home/tag/.virtualenvs/hy/bin/hython', 'test.hy']
(sys.stdout.write "Fuggn' test\n")
; "Fuggn' test"

Naturally, not to be outdone, I decided to amp it up. Django in Lisp While insane, the big stuff looks like this: I ve replaced urls.py with urls.hy:

; vim: tabstop=2 expandtab shiftwidth=2 softtabstop=2 filetype=lisp
(import ["django.conf.urls"])
(def urlpatterns (django.conf.urls.patterns ""
  (django.conf.urls.url "^$" "djlisp.hellisp.views.home")
))

And, views.py with views.hy:

; vim: tabstop=2 expandtab shiftwidth=2 softtabstop=2 filetype=lisp
(import ["django.shortcuts"])
(def home (fn [request]
  (django.shortcuts.render_to_response "home.html"  )))

And lastly, the settings.hy file. I m not going to paste it because it s huge. But, it works!
