Romain Francoise: Rectangles are the new squares

I'm thrilled to find out that Facebook has a group named The CTRL-X R K appreciation society; I'm member #4. C-x r k is one of my favorite Emacs commands.

Benjamin Mako Hill: Revealing Errors

Groups that campaign for free technology, like the Free Software Foundation and the Electronic Frontier Foundation, tend to be supported primarily by technologists. Both groups have struggled to communicate their messages to non-geeks. I have written an article and helped create a new weblog, both called Revealing Errors, that attempt to address a root cause of this issue in what I hope is both an insightful and entertainingly manner. Geeks support groups like the FSF and EFF because, as people who understand technology, they understand just how powerful technology is. Geeks know that control of our communication technologies is control over what we can say, who we can say it to, and how and when we can say it. In an increasingly technologically mediated age, control over technology is not only the power to control our actions; it is the power to limit our possible actions. Our freedom to our technology is our freedom, full stop. This message fails to resonate with non-geeks but it does not fail because non-geeks are happy to hand over their freedom. It fails to resonate simply because the vast majority of people do not understand that technology, and control over it, is powerful enough to impact their freedom. Most people fail to see the power because, quite simply, most people fail to see technology. While we all see the effects of technologies, the technologies themselves are frequently hidden. We see emails but not mail transport agents. We see text messages but not the mobile phone network. Before one can argue that such systems must be free, one must reveal their existence. Technologists are keenly aware of the existence of these systems. To everyone else, they are completely invisible. Marc Weisner of Xerox PARC cited eyeglasses as an ideal technology because, with spectacles, "you look at the world, not the eyeglasses." When technology works smoothly, its nature and effects are invisible. But technologies do not always work smoothly. A tiny fracture or a smudge on a lens renders glasses quite visible to the wearer indeed. Similarly, people see their MTAs when messages bounce. They see Windows on their ATM or phone when the system crashes. Technological errors are moments when usually invisible technology becomes visible. They are, in this sense, also an educational opportunity. /copyrighteous/images/blue_screen.jpg I have recently published an article in Media/Culture Journal from the University of Melbourne within a special issue called Error. If you are interested in learning more about what I'm trying to do or looking at some examples, please read the article. With support and ontributions from Aaron Swartz, I have also created a new weblog, Revealing Errors, that reveals errors that reveal technology by posting descriptions of errors with commentary on what the error reveals. I've posted a few examples there already and I will be updating it regularly. The goal is to help explain the power and influence of technology in the service of broadening the base of people who can get excited about freedom to technology. Eventually, I hope to be able to communicate this message to a less technical audience. With that said, I hope that even seasoned technologists will learn things about their technological environment through the analysis and interaction. I hope readers of this blog will subscribe to it and, if possible, comment on and contribute to the project as it moves forward.

Dirk Eddelbuettel: New York Marathon 2007

I was in New York last weekend to run the 37th New York Marathon which reportedly currently stands as the largest marathon ever run in terms of starters and finishers. And it couldn't have happened on a nicer day: sunny at the start with temperatures in the 50s, no wind, and some clouds in the second half prevented it from getting too hot. Large crowds at most parts of the course, a decent number of bands, and a generally very excited atmosphere. And of course a nice course across the five buroughs finishing in Central Park. For once, I managed to run the race steadily and yet fairly fast, ending up with a time of 3:18:47 (and thus a 7:35 pace). This is about a minute slower than my PR from Sunburst 2006, and just two seconds faster than my best Chicago Marathon result from 2006, yet much better than this year's times from Boston 2007 where it was too cold, and Chicago 2007 where it was way too hot. Given that the NY course is somewhat hillier, and that was definitely busier and more crowded than the other races, I'm quite happy with the time, and the way I ran, getting through without any walking breaks. Not quite negative splits at around 1:38 and 1:40 for the two halfes. With enough energy left at the end, I finished the remaining 2+ km after the 40 km with a sub-7:00 min/mile pace which felt great. And it is a nice feeling to have completed the Boston, Chicago and now New York marathons in the same year. Last but not least, the weekend was a general blast as I was staying with a friend I hadn't seen in a decade which made for lots of stories, and even more beers...

Christian Perrier: RWC: That will be South Africa-England

...and, really, we nearly never thought that Argentina could win tonight. South Africa was really too strong for them. The only domain where Argentinians dominated were scrums but this was much compensated by their great weakness on line-outs, losing something like 5 or 6 of them. South Africa thus logical won very easily...and Bryan Habana is now the best try scorer all along RWCs, along with Jonah Lomu. He is a really great player, indeed. Much much impressive South Africa: they'll be by far the favourites of the final against England, which they beated already during that World Cup. I said several times that I'm not a deep fan of RSA's play, but I could become one. Their game improved all along the World Cup and today, they probably played their best match. Two remakes next week-end: France-Argentina for the 3rd place and South Africa-England as final. That will be good matches, no doubt...and I hope that Bernard Laporte will change the French team to play against Argentina.

Christian Perrier: RWC: Argentina still there, Italy wakes up

After one day off, we watched Argentina-Georgia yesterday evening. Interesting game because it directly affect France's chances to qualify after Argentina's win on Friday. Argentina had a big disadvantage by playing only 4 days after their historic battle against France. As a logical consequence, they appeared quite tired and very imprecise. On the other hand, Georgia fought very courageously with a strong pack of forwards, encouraged by most of the crowd in Lyon. Finally, Argentina won *and* scored the bonus point by scoring a try in the very last minute (which might become very important to qualify in this pool. Good game even if Argentina was not that impressive, but I still think this is mostly because of the 4-days delay. Today, 3 games were scheduled. We didn't watch USA-Tonga (15-25). USA was slightly favourite for that one but they also were quite tired by playing 4 days only after their battle against England on Saturday. This was the first match for Tonga and obviously the island players were less tired and played a good rugby to win that one. Japan-Fidji (31-35) seems to have been the most uncertain match as of now. I somewhat regret not watching it as these two are among the teams I like watching and 7 tries in the match probably made it very interesting. Tonight, we watched Italy-Romania (24-18). The italians compete with Scotland for the remaining qualifying spot in that pool, if one assumes that New Zealand will obviously win all its matches. So, Italy *had* to win that match. The quality of romanian rugby has decreased in the last 10 years, but they still have a good set of great players, most of them playing...in France (just like one third of the italian team, indeed). The match was quite indecise with italy keeping the ball all first half long, but only leading 8-0 on half time....and being surprised by two romanian tries at the beginning of second half (8-12). After a strong domination of Italy, Romania was logically sanctioned by one expulsion and a penalty try (for successive voluntary faults), but, until the end, Italy was still in danger. They finally made it, which was the most important for them, 4 days after they were sweeped out by the All Blacks. We're now eagerly waiting for *THE* game of this week, England-South Africa in the Stade de France on Friday. Elizabeth found out that a few tickets are still available, but for 253 euros each, we decided to watch it on TV. So, between 21:00 and 23:00UTC that day, don't even think about pinging me on IRC. I still haven't decided who I'll support the most as I'm not a huge fan of either team....but they're still among the best in the world, of course.

Emanuele Rocca: Historic GNU information

Today I've stumbled upon this old page about the GNU project.

The last update has been in 1997, it's nice to see how things are changed in 10 years... For instance:

Linux is a copylefted kernel, which uses GNU, BSD and X software to make a compleat free OS. This or FreeBSD or NetBSD are great OS's to use until the Hurd is stable.


There's also an interesting newspaper article about the impact of reward on motivation (1987).

Russell Coker: Squid and SE Linux

Is Squid not returning some data you need on a SE Linux system? The default configuration of the SE Linux policy for Squid only allows it to connect to a small number of ports which are used for web servers. For example ports http (80) and https (443) are labelled as http_port_t which permits serves such as Apache to bind to them and Squid to connect to them. But sometimes services run on non-standard ports and periodically new services are devised which use the HTTP protocol and thus you have Squid and Apache using new ports. semanage port -a -t http_port_t -p tcp 11371 One example of such a port is hkp (11371) - the latest protocol for sending and receiving GPG/OpenPGP keys. Running the above command relabelled the TCP port 11371 in question as http_port_t and thus allowed everything to work. setsebool -P squid_connect_any 1
An alternate option would be to run the above command to allow Squid to connect to any port. I will suggest that the upstream policy be changed to make the default labelling of TCP port 11371 be http_port_t, but the same operations can be used for other ports. Some people may claim that this makes things difficult for sys-admins. But the fact is that a well known port is a significant resource that you don’t want to permit any random user to access. Not only do the SE Linux port access controls prevent malice, but they also prevent system programs from accidentally using the wrong ports. A common example of accidental mis-use is the port 631 used for the IPP (Internet Printing Protocol - CUPS). When system programs need to use TCP source ports below 1024 they start at 1023 and work their way down, having such programs get down to 631 is not uncommon (there are some error conditions which result in ports being reserved for some minutes after use). In terms of malicious operations, it seems that the ports used by database servers such as MySQL and PostgreSQL would ideally be inaccessible to a Squid proxy, and services such as network backup should be inaccessible to everything other than the backup software.

Manoj Srivastava: Manoj: Continuous Automated Build and Integration Environment

One of the things I have been tasked to do in my current assignment is to create a dashboard of the status of various software components created by different contractors (participating companies) in the program. These software components are built by different development groups, utilizing unlike toolsets, languages and tools though I was able to get an agreement on the VCS (subversion yuck). Specifically, one should be able to tell which components pass pre-build checks, compile, can be installed, and pass unit and functional tests. There should be nightly builds, as well as builds whenever someone checks in code on the release branches. And, of course, the dashboard should be HTTP accessible, and be bright and, of course, shiny. My requirements were that since the whole project is not Java, there should be no dependencies on maven or ant or eclipse projects (or make, for that matter); that it should be able to do builds on multiple machines (license constraints restrict some software to Solaris or Windows), not suck up too much time from my real job (this is a service, if it is working well, you get no credit, if it fails, you are on the hot seat). And it should be something I can easily debug, so no esoteric languages (APL, haskell and Python :P) So, using continuous integration as a google search term, I found the comparison matrix at Damage Control I looked at anthill, and cruisecontrol, and the major drawback people seemed to think it had was that configuration was done by editing an XML file, as opposed to a (by some accounts, buggy) UI is not much of a factor for me. (See this). I also like the fact that it seems easier to plug in other components. I am uncomfortable with free software that has a commercial sibling; we have been burned once by UML software with those characteristics. Cruisecontrol, Damagecontrol, Tinderbox1 & tinderbox2, Continuum, and Sin match. I tried to see the demo versions; Sin s link led me to a site selling Myrtle Beach condo s, never a good sign. Continuum and Damagecontrol were currently down, so I could not do an evaluation. So, here are the ones I could get to with working demo pages: http://cclive.thoughtworks.com/ and http://tinderbox.mozilla.org/showbuilds.cgi?tree=SeaMonkey Cruisecontrol takes full control, checking things out of source control; and running the tests; which implies that all the software does build and run on the same machine this is not the case for me. Also, CC needs to publish the results/logs in XML; which seems to be a good fit for the java world; but might be a constraint for my use case. I like the tinderbox dashboard better, based on the information presented; but that is not a major issue. It also might be better suited for a distributed, open source development model; cruisecontrol seems slightly more centralized more on this below. cruisecontrol is certainly more mature; and we have some experience with it. Tinderbox has a client/server model, and communicates via EMAIL to a number of machines where the actual build/testing is done. This seems good. Then there is flamebox nice dashboard, derivative of tinderbox2; and seems pretty simple (perhaps too simple); and easily modifiable. However, none of these seemed right. There was too much of an assumption of a build and test model and few of them seemed to be a good fit for a distributed, Grid-based software development; so I continued looking. Cabie screen shot. I finally decided CABIE
Continuous Automated Build and Integration Environment. Cabie is a multi-platform, multi-cm client/server based application providing both command line and web-based access to real time build monitoring and execution information. Cabie builds jobs based upon configuration information stored in MySQL and will support virtually any build that can be called from the command line. Cabie provides a centralized collection point for all builds providing web based dynamic access, the collector is SQL based and provides information for all projects under Cabie s control. Cabie can be integrated with bug tracking systems and test systems with some effort depending on the complexity of those systems. With the idea in mind that most companies create build systems from the ground up, Cabie was designed to not have to re-write scripted builds but instead to integrate existing build scripts into a smart collector. Cabie provides rapid email notification and RSS integration to quickly handle build issues. Cabie provides the ability to run builds in parallel, series, to poll jobs or to allow the use of scripted nightly builds. Cabie is perfect for agile development in an environment that requires multiple languages and tools. Cabie supports Perforce, Subversion and CVS. The use of a backend broker allows anyone with perl skills to write support for additional CM systems.
The nice people at Yo Linux have provided a Tutorial for the process. I did have to make some changes to get things working (mostly in line with the changes recommended in the tutorial, but not exactly the same. I have sent the patches upstream, but upstream is not sure how much of it they can use, since there has been major progress since the last release. The upstream is nice and responsive, and have added support in unreleased versions for using virtual machines to run the builds in (they use that to do the solaris/windows builds), improved the web interface using (shudder) PHP, and and all kinds of neat stuff.

Joey Hess: announcing etckeeper

Keeping /etc in git and other version control systems has been talked about and attempted by lots of people. I tried it with CVS, but that was a joke, with svn, but it sucked, now with git I actually have something I think I'm happy enough about to use. There's already a tool to do this, but I was not really impressed with isisetup. After considerable pain to find the source code (download links that resolve to 192.168. addresses are niice), I found that it was pretty old and had lots of weird hardcoded things like server names, and it wants to be a git porcelin with its own set of commands for manipulating the /etc repository. I don't want that, I just want a simple setup procedure that lets me use regular git commands to manage the repo. So instead I followed the lead of these blogs combined with David H rdeman's metastore for solving the metadata storage problem. I also hacked in a solution to the empty directory storage problem, and a few other issues with trying to use git for this thing that it was not really designed for. I'm very happy with the way it works, you just run "etckeeper init" and then can commit etc as usual with the file permissions etc included in the commits. Clone the same repo to elsewhere and again "etckeeper init" is all you need to restore those permissions (be sure to not clone the repo to a world readable directory, as there is a window when files would be readable). Automatically committing changes at the end of apt runs is also a handy feature. :-) etckeeper is currently only available from git. ftp-master is down so I can't upload packages, but both it and metastore can be built from git easily enough:
git clone git://git.hardeman.nu/metastore.git; cd metastore; dpkg-buildpackage
git clone git://git.kitenet.net/etckeeper; cd etckeeper; dpkg-buildpackage

Jonathan McDowell: What to do if your TomTom loses its memory

If you should discover, while sitting in a airport departure lounge, that your TomTom has lost its SD card, don't despair. Provided you have a spare SD card (I stole the one from my camera) and have the laptop you've used TomTom Home with to hand, all might not be lost. I was able to do something along the lines of:
cd /media/disk
cabextract ~noodles/TomTom/HOME/Downloads/navcore_7.131.8483.one.cab
mkdir "US - Western Region"
cd US\ -\ Western\ Region/
cabextract ~noodles/TomTom/HOME/Downloads/US_-_Western_Region.cab 
cd
umount /media/disk
which got me up and running again. Of course it doesn't have the UK maps that came with the device, but as I was on my way to the US that's not so important (and Katherine has found the SD card anyway, so I can just replace it when I return). I was quite pleased with myself. And then I ended up with a rental car that had GPS of its own anyway... (Oh, yes, I'm in Fremont, CA, flying back on the morning of Saturday 18th November. I am currently jetlagged and trying hard not to go to bed. If you are in the area, know me and would like to meet up for food/beer/whatever feel free to drop me an email.)

Gerfried Fuchs: 1408, Chuck & Larry, Lissi

Some people say, write it right ahead or you won't write it at all. I fear the latter, thus I'm trying to catch up with things that happend in the last months. Not that I didn't mention some aspects, but I haven't written about some others and want to keep them at least for myself in good rememberance. There were some movies I went to, and some of them I totally enjoyed. First thing was "1408"—a horror shocker with John Cusack, and I really enjoyed it. I'm not a big fan of splatter horror, and this wasn't, it's a pretty nice done psycho shocker. If you still have the chance and like the genre, go and watch it. :) Then there was "I Now Pronounce You Chuck and Larry" which I watched even twice, with both my best friends. One would expect it being more cliche, more shallow—but it isn't. It really astonished me a fair bit how well it tackles the topic, and as an additional benefit the soundtrack of the movie is yet another must-have. Which brings me to "Lissi und der wilde Kaiser". Don't. Just... don't. This one is cliche, this one is shallow. Some small jokes, weakly connected to some story... Bully, you did way better before. Alright, first round of catching up, more to come. After all I'm syndicated on some Free Software related planets, and people might be interested in what's getting done in those parts, too. Not that I would do things in secret...

John Goerzen: Viper

Well, now this is quite the experience.

I've been trying Viper for the past few days. Viper, for those that don't know, is usually described as a set of Vi bindings for Emacs.

After reading the nearly 100 pages of documentation and trying it a bit, I have realized that this is not really an accurate description. Viper is a port of vi to Elisp.

But that doesn't really do it justice. Viper seems to have pretty much everything going for it that Vim does, and then some. It is extensible with Elisp, and works with all the Emacs major modes (indentation and so forth). Yet it also is a very authentic Vi implementation, yet more customizable than Vim. And, in my opinion, more capable than Vim too.

On the one hand, this is a really neat combination: the power of the vi editing commands with the power of Emacs and Elisp for indentation, customization, etc.

On the other hand, it makes my head hurt. While Viper and Vim both are supersets of the vi command set, they don't always implement extensions (such as multiple windows) the same way or with the same keys. Of course, you could remap them in both, but it's a bit jarring to run Viper in expert mode, press C-w to start creating a new window, and have it run the Emacs cut command. (You can run Viper in a more limited mode where it does not recognize any regular Emacs keys if you don't want that)

It's just weird. It mostly looks like Emacs. It is modal like Vim, and responds to all Vi and most Vim commands. It has an additional mode: the Emacs mode. Also if configured to run in expert configuration, Emacs commands are accepted most places. Yes, you can move with h, j, k, l and C-n, C-p, C-f, C-b all at the same time.

The main drawback I can see is that Viper mode doesn't work well with Info mode, which has other bindings for keyboard shortcuts... so all of a sudden, hjkl don't work in info mode.

I don't know yet if I'll use viper much, but it is a slick program.

Manoj Srivastava: Manoj: Filtering accuracy: Hard numbers

I have often posted on the accuracy of my mail filtering mechanisms on the mailing lists (I have not had a false positive in years, and I stash all discards/rejects locally, and do spot checks frequently; and I went through 6 months of exhaustive checks when I put this system in place). False negatives are down to about 3-4 a month (0.019%). Yes, that is right: I am claiming that my classification correctness record is 99.92 (99.98% accuracy for messages my classifiers are sure about). Incorrectly classified unsure ham is about 3-4(0.019%) a month; incorrectly classified unsure Spam is roughly the same, perhaps a little higher. Adding these to the incorrect classification, my best estimate of not confidently classified mail is 0.076%, based on the last 60 days of data (which is what gets you the 99.92%). I get unsure/retrain messages at the rate of about 20 a day (about 3.2% of non-spam email) about 2/3 rds of which are classified correctly; but either SA and crm114 disagree, or crm114 is unsure. So I have to look at about 20 messages a day to see if a ham message slipped in there; and train my filters based on these; and the process is highly automated (just uses my brain as a classifier). The mail statistics can be seen on my mail server. Oh, my filtering front end also switches between reject/discard and turns grey listing on and off based on whether or not the mail is coming from mailing lists/newsletters I have authorized; mimedefang-filter However, all these numbers are manually gathered, and I still have not gotten around to automating my setup s overall accuracy, but now I have some figures on one of the two classifies in my system. Here is the data from CRM114. I ll update the numbers below via cron. First, some context: when training CRM114 using the mailtrainer command, one can specify to leave out a certain percentage of the training set in the learn phase, and run a second pass over the mails so skipped to test the accuracy of the training. The way you do this is by specifying a regular expression to match the file names. Since my training set has message numbers, it was simple to use the least significant two digits as a regexp; but I did not like the idea of always leaving out the same messages. So I now generate two sets of numbers for every training run, and leave out messages with those two trailing digits, in effect reserving 2% of all mails for the accuracy run. An interesting thing to note is the assymetry in the accuracy: CRM114 has never identified a Spam message incorrectly. This is because the training mechanism is skewed towards letting a few spam messages slip through, rather than let a good message slip into the spam folder. I like that. So, here are the accuracy numbers for CRM114; adding in Spamassassin into the mix only improves the numbers. Also, I have always felt that a freshly learned css file is somewhat brittle in the sense that if one trains an unsure message, and then tried to TUNE (Train Until No Errors) the css file, a large number of runs through the training set are needed until the thing stabilizes. So it is as if the learning done initially was minimalistic, and adding the information for the new unsure message required all kinds of tweaking. After a while TOEing (Training on Errors) and TUNEing, this brittleness seems to get hammered out of the CSS files. I also expect to see accuracy rise as the css files get less brittle The table below starts with data from a newly minted .css file.

Lucas Nussbaum: Some numbers about Debian s history

There’s an interesting article on LWN.net about Gentoo: Who made Gentoo Linux, and when? A commit analysis I was wondering how Debian compared, so I made some stats using the debian-devel-changes archives. First, the number of source uploads per quarter:
It’s interesting to note that, while the number of packages in Debian increased a lot, the number of uploads basically stayed the same since 2001. Then, I wondered about the number of active developers in Debian. So I counted: I can provide the raw data on demand, if someone else want to work on this. There’s probably a lot of other interesting things to do!
