Martin F. Krafft: Extending the X keyboard map with xkb

xmodmap has long been the only way to modify the keyboard map of the X server, short of the complex configuration daemon approaches used by the large desktop managers, like KDE and GNOME. But it has always been a hack: it modifies the X keyboard map and thus requires a baseline to work from, kind of like a patch needs the correct context to be applicable. Worse yet, xmodmap weirdness required me to invoke it twice to get the effect I wanted. When the recent upgrade to X.org 7.4 broke larger parts of my elaborate xmodmap configuration, I took the time to finally ditch xmodmap and implement my modifications as proper xkb configuration.

Background information I had tried before to use per-user xkb configuration, but could not find the answers I want. It was somewhat by chance that I found Doug Palmer s Unreliable Guide to XKB configuration at the same time that Julien Cristau and Matthew W. S. Bell provided me the necessary hints on the #xorg/irc.freenode.org IRC channel to get me started. The other resource worth mentioning is Ivan Pascal s collection of XKB documents, which were instrumental in my gaining an understanding of xkb. And just as I am writing this document, Debian s X Strike Force have published their Input Hotplug Guide, which is a nice complement to this very document you are reading right now, since it focuses on auto-configuration of xkb with HAL. The default xkb configuration comes with a lot of flexibility, and often you don t need anything else. But when you do, then this is how to do it:

Installing a new keyboard map The most basic way to install a new keyboard map is using xkbcomp, which can also be used to dump the currently installed map into a file. So, to get a bit of an idea of what we ll be dealing with, please run the following commands:
xkbcomp $DISPLAY xkb.dump
editor xkb.dump
xkbcomp xkb.dump $DISPLAY

The file is complex and large, and it completely went against my aesthetics to simply edit it to have xkb work according to my needs. I sought a way in which I could use as much as possible of the default configuration, and only place self-contained additional snippets in place to do the things I wanted done differently. setxkbmap and rule files Thus began my voyage into the domain of rule files. But before we dive into those, let s take a look at setxkbmap. Despite the trivial invocation of e.g. setxkbmap us to install a standard US-American keyboard map, the command also takes arguments. More specifically, it allows you to specify the following high-level parameters, which determine the sequence of events between key press and an application receiving a KeyPress event:
  • Model: the keyboard model, which defines which keys are where
  • Layout: the keyboard layout, which defines what the keys actually are
  • Variant: slight variantions in the layout
  • Options: configurable aspects of keyboard features and possibilities
Thus, with the following command line, I would select a US layout with international (dead) keys for my Thinkpad keyboard, and switch to an alternate symbol group with the windows keys (more on that later):
setxkbmap -model thinkpad -layout us -variant intl -option grp:win_switch

In many cases, between all combinations of the aforementioned parameters, this is all you ever need. But I wanted more. If you append -print to the above command, it will print the keymap it would install, rather than installing it:
% setxkbmap -model thinkpad -layout us -variant intl -option grp:win_switch -print
xkb_keymap  
  xkb_keycodes    include "evdev+aliases(qwerty)"        ;
  xkb_types       include "complete"     ;
  xkb_compat      include "complete"     ;
  xkb_symbols     include "pc+us(intl)+inet(evdev)+group(win_switch)"    ;
  xkb_geometry    include "thinkpad(us)"         ;
 ;

There are two things to note:
  1. The -option grp:win_switch argument has been turned into an additional include group(win_switch) on the xkb_symbols line, just like the model, layout, and variant are responsible for other aspects in the output.
  2. The output seems related to what xkbcomp dumped into the xkb.dump file we created earlier. Upon closer inspection, it turns out that the dump file is simply a pre-processed version of the keyboard map, with include instructions exploded.
At this point, it became clear to me that this was the correct way forward, and I started to investigate those points in order. The translation from parameters to an xkb_keymap stanza by setxkbmap is actually governed by a rule file. A rule is nothing more than a set of criteria, and what setxkbmap should do in case they all match. On a Debian system, you can find this file in /usr/share/X11/xkb/rules/evdev, and /usr/share/X11/xkb/rules/evdev.lst is a listing of all available parameter values. The xkb_symbols include line in the above xkb_keymap output is the result of the following rules in the first file, which setxkbmap had matched (from top to bottom) and processed:
! model         layout              =       symbols
  [...]
  *             *                   =       pc+%l(%v)
! model                             =       symbols
  *                                 =       +inet(evdev)
! option                            =       symbols
  [...]
  grp:win_switch                    =       +group(win_switch)

It should now not be hard to deduce the xkb_symbols include line quoted above, starting from the setxkbmap command line. I ll reproduce both for you for convenience:
setxkbmap -model thinkpad -layout us -variant intl -option grp:win_switch
xkb_symbols     include "pc+us(intl)+inet(evdev)+group(win_switch)"    ;

A short note about the syntax here: group(win_switch) in the symbols column simply references the xkb_symbols stanza named win_switch in the symbols file group (/usr/share/X11/xkb/symbols/group). Thus, the rules file maps parameters to sets of snippets to include, and the output of setxkbmap applies those rules to create the xkb_keymap output, to be processed by xkbcomp (which setxkbmap invokes implicitly, unless the -print argument was given on invocation). It seems that for a criteria (option, model, layout, ) to be honoured, it has to appear in the corresponding listing file, evdev.lst in this case. There is also evdev.xml, but I couldn t figure out its role.

Attaching symbols to keys I ended up creating a symbols file of reasonable size, which I won t discuss here. Instead, let s solve the following two tasks for the purpose of this document:
  1. Make the Win-Hyphen key combination generate an en dash ( ), and Win-Shift-Hyphen an em dash ( ).
  2. Let the Caps Lock key generate Mod4, which can be used e.g. to control the window manager.
To approach these two tasks, let s create a symbols file in ~/.xkb/symbols/xkbtest and add two stanzas to it:
partial alphanumeric_keys
xkb_symbols "dashes"  
  key <AE11>  
    symbols[Group2] = [ endash, emdash ]
   ;
 ;
partial modifier_keys
xkb_symbols "caps_mod4"  
  replace key <CAPS>  
    [ VoidSymbol, VoidSymbol ]
   ;
  modifier_map Mod4   <CAPS>  ;
 ;

Now let me explain these in turn:
  1. We used the option grp:win_switch earlier, which told xkb that we would like to use the windows keys to switch to group 2. In the custom symbols file, we now simply define the symbols to be generated for each key, when the second group has been selected. Key <AE11> is the hyphen key. To find out the names of all the other keys on your keyboard, you can use the following command:
    xkbprint -label name $DISPLAY -   gv -orientation=seascape -
    
    
    I had to declare the stanza partial because it is not a complete keyboard map, but can only be used to augment/modify other maps. I also declared it alphanumeric_keys to tell xkb that I would be modifying alphanumeric keys inside it. If I also wanted to change modifier keys, I would also specify modifier_keys. The rest should be straight-forward. You can get the names of available symbols from keysymdef.h (/usr/include/X11/keysymdef.h on a Debian system, package x11proto-core-dev), stripping the XK_ prefix.
  2. The second stanza replaces the Caps Lock key definition and prevents it from generating symbols (VoidSymbol). The important aspect of the second stanza is the modifier_map instruction, which causes the key to generate the Mod4 modifier event, which I can later use to bind key combinations for my window manager (awesome).
The easiest way to verify those changes is to put the setxkbmap -print output of the keyboard map you would like to use as a baseline into ~/.xkb/keymap/xkbtest, and append snippets to be included to the xkb_symbols line, e.g.:
"pc+us(intl)+inet(evdev)+group(win_switch)+xkbtest(dashes)+xkbtest(caps_mod4)"

When you try to load this keyboard map with xkbcomp, it will fail because it cannot find the xkbtest symbol definition file. You have to let the tool know where to look, by appending a path to its search list (note the use of $HOME instead of ~, which the shell would not expand):
xkbcomp -I$HOME/.xkb ~/.xkb/keymap/xkbtest $DISPLAY

You can use xev to verify the results, or just type Win-Hyphen into a terminal; does it produce ? By the way, I found xev much more useful for such purposes when invoked as follows (thanks to Penny for the idea):
xev   sed -ne '/^KeyPress/,/^$/p'

Unfortunately, xev does not give any indication of which modifier symbols are generated. I have found no other way to verify the outcome, other than to tell my window manager to do something in response to e.g. Mod4-Enter, reloaded it, and then tried it out.

Rules again, and why I did not use them in the end Once I got this far, I proceeded to add option-to-symbol-snippet mappings to the rules file, and added each option to the listing file too. A few bugs [[!debbugs 524512 desc=later]], I finally had setxkbmap spit out the right xkb_keymap and could install the new keyboard map with xkbcomp, like so:
setxkbmap -I$HOME/.xkb [...] -print   xkbcomp -I$HOME/xkb - :0

I wrote a small script to automatically do that at the start of the X session and could have gone to play outside, if it hadn t been for the itch I felt due to the entire rule file stored in my configuration. I certainly did not like that, but I could also not find a way to extend a rule file with additional rules. When I looked at the aforementioned script again, it suddenly became obvious that I was going a far longer path than I had to. Even though the rule system is powerful and allows me to e.g. automatically include symbol maps to remap keys on my Thinkpad, based on the keyboard model I configured, the benefit (if any) did not justify the additional complexity. In the end, I simplified the script that loads the keyboard map, and defined a default xkb_keymap, as well as one for the Thinkpad, wich I identify by its fully-qualified hostname. If a specific file is available for a given host, it is used. Otherwise, the script uses the default.

Axel Beckert: Useless Statistics, the 2nd

Myon recently posted a nice statistic about popular single letter package name prefixes. Just out of curiosity I started wondering about popular single letter package name suffixes: On a machine with Debian oldstable, stable, testing, unstable and experimental in its sources.list, I ran the following command:
$ apt-cache search -n .   \
    awk ' print $1 '   \
    sed -e 's/.$//'   \
    sort   \
    uniq -c   \
    sort -n
And to my surprise there is a non-obvious winner:
$ apt-cache search -n '^gp.$'
gpa - GNU Privacy Assistant
gpc - The GNU Pascal compiler
gpe - The G Palmtop Environment (GPE) metapackage
gpm - General Purpose Mouse interface
gpp - a general-purpose preprocessor with customizable syntax
gpr - GUI for lpr: print files and configure printer-specific options
gps - Graphical Process Statistics using GTK+
gpt - G-Portugol is a portuguese structured programming language
gpw - Trigraph Password Generator
But since I searched through the binary packages many other hits are more obvious, like the seven packages hbf-cns40-1 to hbf-cns40-7:

Patrick Winnertz: Midnight Commander revived (new version available)

After everybody though that Midnight Commander is dead and the next release of it will be released together with hurd, it is very cool to announce that a new team of developers are active again. We've taken over officially the development in December and now, after two months of work a new version of mc is available: 4.6.2. This is mostly a bugfix release addressing several very nasty bugs which are also present in the debian package. Here the notes what has changed in this release: As you see.. quite a long list of fixes :) Have fun and check the new release out right here! :)

Russell Coker: The History of MS

Jeff Bailey writes about the last 26 years of Microsoft [1]. He gives Microsoft credit for “saving us from the TRS 80″, however CP/M-86 was also an option for the OS on the IBM PC [2]. If MS hadn’t produced MS-DOS for a lower price then CP/M would have been used (in those days CP/M and MS-DOS had the same features and essentially the same design). He notes the use of the Terminate and Stay Resident (TSR) [3] programs. As far as I recall the TSR operation was undocumented and was discovered by disassembling DOS (something that the modern MS EULAs forbid). Intel designed the 8086 and 80286 CPUs to permit code written for an 8086 to run unchanged in “protected mode” on an 80286 (as noted in the Wikipedia page about the 80286 [4]). Basically all that you needed to do to write a DOS program with the potential of being run directly in protected mode (or easily ported) was to allocate memory by requesting it from the OS (not just assuming that every address above your heap was available to write on) and by addressing memory only by the segment register returned from the OS when allocating memory (IE not assuming that incrementing a segment register is equivalent to adding 16 to the offset). There were some programs written in such a manner which could run on both DOS and text-mode OS/2 (both 1.x and 2.x), I believe that such programs were linked differently. The term Fat Binary [5] is often used to refer to an executable which has binary code for multiple CPUs (EG PPC and M68K CPUs on the Macintosh), I believe that a similar concept was used for DOS / OS/2 programs but the main code of the application was shared. Also compilers which produce object code which doesn’t do nasty things could have their object code linked to run in protected mode. Some people produced a set of libraries that allowed linking Borland Turbo Pascal code to run as OS/2 16bit text-mode applications. The fact that OS/2 (the protected-mode preemptively multi-tasking DOS) didn’t succeed in the market was largely due to MS. I never used Windows/386 (a version of Windows 2.x) but used Windows 3.0 a lot. Windows 3.0 ran in three modes, “Real Mode” (8086), “Standard Mode” (80286), and “Enhanced Mode” (80386). Real Mode was used for 8086 and 8088 CPUs, for 80286 systems if you needed to run one DOS program (there was no memory for running more than one), and for creating or adjusting the swap-file size for an 80386 system (if your 80386 system didn’t have enough swap you had to shut everything down, start Real Mode, adjust the swap file, and then start it again in Enhanced Mode). Standard Mode was the best mode for running Windows programs (apart from the badly written ones which only ran on Real Mode), but due to the bad practices implemented by almost everyone who wrote DOS programs MS didn’t even try to run DOS programs in 286 protected mode and thus Standard Mode didn’t support DOS programs. Enhanced Mode allowed multitasking DOS programs but as hardly anyone had an 80386 class system at that time it didn’t get much use. It was just before the release of Windows 3.1 that I decided to never again use Windows unless I was paid to do so. I was at a MS presentation about Windows 3.1 and after the marketing stuff they had a technical Q/A session. The questions were generally about how to work around bugs in MS software (mainly Windows 3.0) and the MS people had a very detailed list of work-arounds. Someone asked “why don’t you just fix those bugs” and we were told “it’s easier to teach you how to work around them than to fix them“. I left the presentation before it finished, went straight home and deleted Windows from my computer. I am not going to use software written by people with such a poor attitude if given a choice. After that I ran the DOS multi-tasker DesqView [6] until OS/2 2.0 was released. Desqview allowed multitasking well written DOS programs in real mode, Quarterdeck was the first company to discover that almost 64K of address space could be used above the 1MB boundary from real-mode on a 80286 (a significant benefit when you were limited to 640K of RAM), as well as multitasking less well behaved DOS programs with more memory use on an 80386 or better CPU. OS/2 [7] 2.x was described as “A Better DOS than DOS, a Better Windows than Windows”. That claim seemed accurate to me. I could run DOS VM86 sessions under OS/2 which could do things that even Desqview couldn’t manage (such as having a non-graphical DOS session with 716K of base memory in one window and a graphical DOS session in another). I could also run combinations of Windows programs that could not run under MS Windows (such as badly written windows programs that needed Real Mode as well as programs that needed the amount of memory that only Standard or Enhanced mode could provide). Back to Bill Gates, I recently read a blog post Eight Years of Wrongness [5] which described how Steve Ballmer has failed MS stockholders by his poor management. It seems that he paid more attention to fighting Linux, implementing Digital Restrictions Management (DRM), and generally trying to avoid compatibility with other software than to actually making money. While this could be seen as a tribute to Bill Gates (Steve Ballmer couldn’t do the job as well), I think that Bill would have made the same mistakes for the same reasons. MS has always had a history of treating it’s customers as the enemy. Jeff suggests that we should learn from MS that the freedom to tinker is important as is access to our data. These are good points but another important point is that we need to develop software that does what users want and acts primarily in the best interests of the users. Overall I think that free software is quite well written in regard to acting on behalf of the users. The issue we have is in determining who the “user” is, whether it’s a developer, sys-admin, or someone who wants to just play games and do some word-processing.

Anthony Towns: The second half...

Continuing from where we left off… The lower bound for me becoming a DD was 8th Feb ‘98 when I applied; for comparison, the upper bound as best I can make out was 23rd Feb, when I would have received this mail through the debian-private list:
Resent-Date: 23 Feb 1998 18:18:57 -0000
From: Martin Schulze 
To: Debian Private 
Subject: New accepted maintainers
Hi folks,
I wish you a pleasant beginning of the week.  Here are the first good
news of the week (probably).
This is the weekly progress report about new-maintainers.  These people
have been accepted as new maintainer for Debian GNU/Linux within the
last week.
[...]
Anthony Towns <ajt@debian.org>
    Anthony is going to package the personal proxy from
    distributed.net - we don't have the source... He may adopt the
    transproxy package, too.
Regards,
        Joey
I never did adopt transproxy – apparently Adam Heath started fixing bugs in it a few days later anyway, and it was later taken over by Bernd Eckenfels (ifconfig upstream!) who’s maintained it ever since. Obviously I did do other things instead, which brings us back to where we left off…
Geez, this was meant to be briefer...

Martin F. Krafft: Consolidating packaging workflows across distros

I speculate that most of what we do for Debian squares with what others do for their respective distro. Thus, it should be possible to identify a conceptual workflow applicable to all distros, consolidate individual workflows on a per-package basis, and profit from each other. Jonathan let me have the after-afternoon-coffee slot of the Distro Summit for an impromptu discussion on the various workflows used by distros for packaging. The discussion round was very short-notice and despite the announcement sent to the conference mailing list, only ten people showed up: two people familiar with Fedora, and ( versus ) eight Debianites. Regardless, I think the discussion was success- and fruitful. We were able to identify a one-to-one mapping between the Fedora and Debian workflows, even though we use different techniques: Many Debian package maintainers use version control systems to maintain the ./debian directory, and if patch files are stored in ./debian/patches/, then Debian and Fedora both store patch files in a version control repository, which seems awful. Just as I am only one of many who are experimenting with VCS-based workflows for Debian packaging, the Fedora people are also considering the use of version control for packaging. Unlike Fedora, who seem to try to standardise on bzr, I try to cater for the plethora of version control systems in use in Debian, anticipating the impossibility of standardising/converging on a single tool across the entire project. It seems that our two projects are both at the start of a new phase in packaging, a paradigm shift . What better time could there be for us to listen to each other and come up with a workflow that works for both projects? My suggestion currently centres around a common repository for each package across all (participating) distros, and feature branches. Specifically, given an upstream source tree, modifications made during packaging for a given distro fall into four categories: Given a version control system with sufficient branching support, I imagine having different namespaces for branches: upstream-patches/*, distro/*, rpm/* or debian/*. Now, when building the Debian package, I d apply upstream-patches/*, distro/*, deb/* and debian/* in order, while my colleague from the Fedora project would apply upstream-patches/*, distro/*, rpm/* and fedora/*, before calling the build tools and uploading the package. There are surely problems to be overcome. Pascal Hakim mentioned patch dependencies, and I can t necessarily say with a clear conscience that my workflow isn t too complicated to be unleashed into the public yet. But if we find a conceptual workflow applicable to more than one distro, it should be possible to implement a higher-level tool to implement it. Also, the above is basically patch maintenance, not the entire workflow. Bug tracking system integration is going to play a role, as well as other aspects of daily distro packaging. I ll leave those for future time. For me, this is the start of a potentially fruitful cooperation and I hope that interested parties from other distros jump on. For now, I suggest my mailing list for discussion. You can also find some links on the Debian wiki.

Lior Kaplan: Lazarus and fpc in Debian

A friend involved in the Lazarus and Free Pascal Compiler projects told me that they maintain a private repository for their packages. And .deb files for newer versions for Lazarus and fpc are available on SF.net. It’s funny to read the Lazarus Ubuntu repository while Ubuntu is using the Debian packages through the Universe section. And as far as I noticed these are the same packages. Anyway, I don’t think ignoring Debian gives us motivation regarding these packages (at least to myself as I’m not involved with these packages). It seems there’s a good will by Carlos Laviola, the fpc package maintainer and Mazen Neifer from freepascal.org to build the new version for Debian. I think that working tighter may result in better packages for the project. Looking at the Mazen’s changelog reveals that the new version closes 3 bug reports in Debian. But without releasing the source package (or at least the diff.gz file), we can’t really see all the changes done by you. From the changelog, I can also see the private packages don’t use changes done in Debian. Meaning they probably have some bugs already fixed in Debian. I see both people are members of the http://bollin.googlecode.com/svn/fpc/trunk/ repository, so what is the problem? It seems to me that a win-win situation is in our grasp with a little effort which will result in better packages for the fpc community.

Arnaud Vandyck: Fosdem 2007

Organisation Like last year, I did not help Pascal to manage the devrooms. I'd like to be more helpfull so as a lot of people I made a little donation and get a FOSDEM2007 t-shirt. The event was even better than last year (even if I think it's also cool last year except the wifi was not working last year). This is the first time since 2004 that I don't meet Wouter! I hope we'll meet next Debian or FOSDEM meeting. Women Is it me or are there more and more women involved in open source? This is one of the great news form this year. read more

Adam Rosi-Kessel: Grimmelmann and Kozinski on Law

I recently came across two old and unrelated writings about law, both of which are worth reading, especially for people with strong opinions but no formal training. The first is this piece, entitled Seven Ways in Which Code Equals Law (And One in Which It Does Not), by recently-appointed New York Law School professor James Grimmelmann and EFF Legal Director Cindy Cohn. Several observations are particularly appropriate for the slashdot crowd (and, to a lesser extent, certain members of the Debian community and others who grew up on a diet of BASIC, Pascal, and then C and later perl). I especially like this bit about “hacking the law”:
Some people, seeing this connection, and remembering the values of good code, try to improve the legal system by treating it as a computer. People come to me with ideas for hacking the law. The government says that cryptography is a weapon, they say, but the Bill of Rights says we have the right to bear arms. So that means we have a Constitutional right to use cryptography. But the legal system isn t a computer. If you can t convince a judge that what you re proposing is consistent with the values underlying a law, your argument will go nowhere. People go to jail every year because they think they ve found a way to hack the Sixteenth Amendment. The income tax is illegal, they say, or, The income tax is voluntary, see, it says so right here, and then they get convicted of tax evasion and sent to jail. We did convince several judges about the Constitutional dimension of cryptography, but the claim started from the values of the First Amendment, not a mechanical reading of its words. It s a category mistake to treat the legal system as just another architecture with its own specialized language. Code and law are different ways of regulating; they have different textures. All of those people who are required to make the legal system work leave their mark on its outcomes: they make a certain amount of drift and discretion almost inevitable. Code doesn t have such a limit: it can make perfectly hard-nosed bright-line rules and hold everyone in the world to them. Code is capable of a kind of regulatory clarity and intensity that law can only state, never really achieve.
I don’t entirely agree with the other article, entitled What I Ate For Breakfast and Other Mysteries of Judicial Decision Making by outspoken Ninth Circuit Judge Alex Kozinski (unofficial site maintained by Aaron Swartz, wikipedia entry). For example, I think critical legal studies has resulted in some interesting insights, some of which actually have practical applciation. Still, Judge Kozinski makes an important point about the numerous factors that act as a check on discretion in judicial decisionmaking:
It is popular in some circles to suppose that judicial decision making can be explained largely by frivolous factors, perhaps for example the relationship between what judges eat and what they decide. Answering questions about such relationships is quite simple - it is like being asked to write a scholarly essay on the snakes of Ireland: There are none. But as far back as I can remember in law school, the notion was advanced with some vigor that judicial decision making is a farce. Under this theory, what judges do is glance at a case and decide who should win - and they do this on the basis of their digestion (or how they slept the night before or some other variety of personal factors). If the judge has a good breakfast and a good night’s sleep, he might feel lenient and jolly, and sympathize with the downtrodden. If he had indigestion or a bad night’s sleep, he might be a grouch and take it out on the litigants. Of course, even judges can’t make both sides lose; I know, I’ve tried. So a grouchy mood, the theory went, is likely to cause the judge to take it out on the litigant he least identifies with, usually the guy who got run over by the railroad or is being foreclosed on by the bank. This theory immodestly called itself Legal Realism. Just to prove that even the silliest idea can be pursued to its illogical conclusion, Legal Realism spawned Critical Legal Studies. As I understand this so-called theory, the notion is that because legal rules don’t mean much anyway, and judges can reach any result they wish by invoking the right incantation, they should engraft their own political philosophy onto the decision-making process and use their power to change the way our society works. So, if you accept that what a judge has for breakfast affects his decisions that day, judges should be encouraged to have a consistent diet so their decisions will consistently favor one set of litigants over the other. I am here to tell you that this is all horse manure. And, like all horse manure, it contains little seeds of truth from which tiny birds can take intellectual nourishment. The little truths are these: Under our law judges do in fact have considerable discretion in certain of their decisions: making findings of fact, interpreting language in the Constitution, statutes and regulations; determining whether officials of the executive branch have abused their discretion; and, fashioning remedies for violations of the law, including fairly sweeping powers to grant injunctive relief. The larger reality, however, is that judges exercise their powers subject to very significant constraints. They simply can’t do anything they well please.
Finally, I will link, but not embed, this video of the Anna Nicole Smith court order, for an entirely different perspective on the legal process. You almost don’t really want to have to see this stuff.

Joachim Breitner: DeCaf taking on form

A few month ago, I blogged a way to spread Free Software effectively, especially in developing countries: By deploying Free Software in internet caf s, where most people learn their way around computers. Most of them (and there are a lot, much more than in Europe) have a buisness plan that relies on software for free, but currently they achieve that through pirating Windows and software like Cybercafe Pro. Back than, I wrote this more or less theoretically, but it happend that I ended up having some time to actually start working on it.While Free Software, especially Debian, provides a very good base to build internet caf s from, one key component is more or less missing: Software to hand out these codes ( timecodes ) to the customer, to let them log in and surf for the time they bought. Very recently, Zybacafe was released, but I did not really like it, nor felt like maintaining a Pascal/Lazarus based Debian package. So I went ahead and implemented my own ideas.The Idea is to keep it very simple, very modularized and integrate deeply with normal unix ideas. So what we have now is a PostgreSQL database (one table so far), and all communication just goes via this table, so we don t have to design or implement complicated protocols. A python gtk application for the front desk generates the timecodes that are then, on paper, passed to the customer. The workstations greet the user with standard GDM, but our pam modules authenticates the timecode instead of a username/password pair. While using the system, a small floating window informs the user about the remaining time. If he does not log out voluntarily, a system daemon will kill all his processes eventually.The long term mission is to form that into a Custom Debian Distribution that will install the server hassle-less, and besides being pre-configured for the internet caf s needs, also immediately serves as an automated installation server for the workstations (think FAI), all useing stock Debian packages, as far as possible. Another pam module could, upon login, mount the homedirectory as a copy-on-write overlay of a template user s home directory, and through away the changes afterwards. The goal is to offer easier installation, less maintenance, better robustness and more flexibility than the current common non-free systems.But, of course, this project needs help. First of all: Users! If you have any use for time-limited logins (Internet caf , school surf terminaly, parents with otherwise not to bed going kids), you can be an earliy adaptor. Developers are very welcome as well, and due to the modular structure, cooperation should be quite smooth.The development happens on alioth, where we have the subversion repositry, as well as on the Debian wiki page. Alpha packages for these components can be found on the alioth group s webspace. We do not have a mailing list yet, but feel free to e-mail me. We will set up a mailing list once there is a need for it. Thank s to the KACE for supporting this.

Zak B. Elep: Who moved my sundae?

WTF IS THIS SHIT? Ok, that above would be what a newly-baptized “FOSS advocate-slash-zealot” would say upon seeing Federico Pascual Jr.’s PostScript regarding the FOSS bill. I suppose I could have said that myself a couple of lifetimes ago. But, there is more than meets the eye. While I would like to think of myself as a “FOSS veteran”–believe me, I have still so much to learn about it–I would like to step into the shoes of such a person when approaching an article as sensational as Mr. Pascual’s. Despite what seems to be a most interesting article on the mechanics of government software usage, it fails to address the one particular bit that is just as important as the proposed bill itself: the real Free and Open Source Software. Let me nitpick this article bit by bit:
FREE RIDE: A bill is being pushed in Congress forbidding all government agencies and state-controlled firms from buying and using any of the computer software sold in the market!
Alas, when I first heard of the FOSS bill sometime before September, I also had a bad impression of it. Perhaps I was just too politically allergic at that time (yeah right,) but I tried to adopt a wait-and-see’ approach first and let the dice roll. Perhaps because this bill was to be introduced by a very visible congressman with alleged leftist ties made me feel uncomfortable, but then, so was (and still is) with the current administration. Or perhaps I just felt it wasn’t damn right to legislate FOSS as an end-all solution, preferring instead of presenting is as a process for reforming the local software industry. Looks like first impressions definitely make a difference.
The proposed law to be called “Free/Open Source Software (FOSS) Act of 2006″ commands government offices to use only information and communications software that are given away for free and have no restrictions as to their use. The objectives appear to be to save money for the government and to encourage the making of free (non-commercial) software.
So? What’s wrong with these objectives? FWIW, the early FOSS bill draft did seem to have such a Draconian section as forcing the government and allied offices to use, and use only, FOSS. IMHO that by itself ran against the very fundamental ideal of FOSS: the freedom of choice. Not Hobson’s choice, but real choice. The current bill IIRC now allows this true choice; unless there is an extreme case where FOSS cannot be applied without becoming non-self-sustaining (not to mention self-liquidating,) agencies may implement their infrastructure using FOSS as their primary instrument, with the application of open standards (that is, open document formats, open communications protocols, etc) unifying the disparate components. Perhaps right now, this situation may seem kind of far-fetched, but its not really that far-off, considering what other nations and cities have done (or not done) with FOSS. Munich, Extremadura, Beijing… the list is not yet that long, but its bound to go a long way ;-) Now, while the government may now adopt open standards and open-everything, does not mean that the openness’ forgoes security, either; the government may opt to use well-known encryption protocols and even base their own security infrastructure on them. In fact, they are free to even look inside the source of these well-known standards, to study them, and to branch off new implementation that may even change the way these standards work. In fact, even without this bill in place, the government can participate in the production and development of FOSS!!! Wait a minute, wasn’t I supposed to defend this bill? Eh, well. I suppose this bill is good and all, but like I said earlier, there are those first impressions made by the parties involved in the making of this bill which unsettles me. IMHO I would rather see applications of this first in key cities (the happy works in Munich and in Extremadura are no accident, believe me) which in turn, would allow both local the national government to see just exactly how this FOSS magic works. Then, when the observations have been made, the papers are in, and the workers get hired, then, maybe, we’ll have a nation where FOSS can be mandated as a very strong preference, but never a forced one. Its all about growing up, really. I’m being reminded of Tom DeMarco’s The Deadline, where a newly-retrenched guy from a telco literally lands into the fantastic job of his life, managing an entire nation of software engineers and architects to develop several killer apps within a year (or so; raid you nearest Book Sale and be lucky ;) Its a great experiment: when it succeeds, you’ll be the first to be present, but when it fails, you’ll be the first to be nowhere.
But I can also hear in the background a call to an unholy war against multinationals whose popular software run virtually all maybe 95 percent? of the computers of the world.
Now this is a low blow. Maybe partly because of the prevailing images of the advocates–geeks and leftists, my, what a c-c-c-combo!–is what drives Mr. Pascual to make this point. But really, multinationals are not the main concern. FWIW, FOSS is multinational in nature: it is even multi-denominational and multidisciplinary. FOSS is one of the things that make anonymous people like you and me Internet superheroes. FOSS connects the Internet’s tubes and keeps away the trucks. FOSS makes the Internet serious business, yet also drives them crazy. The Linux distros that I have worked, am working, and continue to work on, are all multinational: Debian and Ubuntu. People from all over the world, from all 7 continents, participate and work on what would arguably be the biggest software distribution the human world may ever produce, freely, regardless of motivation or goal. I suppose all the folks involved have only one common goal, and that is to see a work created for the benefit of the community by the community. I suppose the background howl comes from somewhere altogether, but its hardly just from FOSS. FOSS is the epitome of what is truly multinational, and one thing that is not truly controlled by any one single person, corporation or not.

Kenshi Muto: i386 d-i image for Sarge, with kernel 2.6.18 (early test release)

Last week Pascal, who is a friend of bubulle, asked me how he could make ISO image with kernel 2.6.18 for Sarge. Timely I'd like to have a kernel 2.6.18 image for myself also (I bought Core2Duo machine. It has VIA VT8237A SATA controller isn't supported before 2.6.18), I made it. You can take it from the usual place; sarge-custom-1008.iso for i386.

Pascal Hakim: Teams.debian.net

One of the things I've been working on, on and off for the last few months is teams.debian.net. Along with a few others, we felt that there were not enough options for Debian-related mailing list hosting. While this may seem strange to some, a number of people at DebConf5 found the idea to be worthwhile. Most Debian-related lists which would not be considered for lists.debian.org could find hosting at teams.debian.net instead. The main purposes behind teams.debian.net are:
To request a new mailing list, simply follow the instructions on teams.debian.net Of course, like any free software project, there are still some things which are needed. The main one is currently the lack of a public web archive for lists which want it. I wanted to try to replace MHonArc with something that looked a little better and was more user-friendly, but I have yet to find something which I think would be an appropriate replacement. While some have suggested Lurker, I feel that is not very useable in a long term hosting environment, as it is harder to navigate around older entries. While this is acceptable in some places, it's definitely not in others. You can consider a "Dear Lazyweb" paragraph if you wish. Many thanks to Andreas Barth and Martin Zobel-Helas for their help in setting this up, providing machine space, and prodding me along when necessary.

Martin F. Krafft: Open in browser

Mozilla Firefox bug #57342 was the first bug I encountered after I had completed my switch from Galeon (which got infected by GNOME2-itis, such that you could not change basic browser settings without gnome-control-panel). It's still a bug, but I of course understand the Firefox developer's decision that a user's request to be able to view simple text files inline (<gasp>) is a low priority improvement. I won't allow myself to make a comment about the Firefox code quality that in six years, noone has come up with a working patch for this massive challenge. Do they have to switch their browser into protected memory mode and load a DOS emulator to be able to handle plain text? Fortunately, I have since found this extension. Now my life is really much simpler.

Christian Perrier: Computerworld.au news entry about Dzongkha Linux

After the DzongkhaLnux launch event which I already blogged about as well as published a report in debian-devel-announce, I got interviewed by Computerworld.au. They turned this interview into one of their head stories, which IMHO gives Debian an interesting exposure. Moreover, I am very happy of the way they wrote the story, which gives Debian the credit it deserves in that story and gives a very good transcription of my own ideas about free software. It also puts yet more exposure on the Bhutanese authorities initiative and I think they really deserve it as well. Thanks indeed to Pascal Hakim who made this possible and to Dahna McConnachie who wrote the news entry and conducted the interview.
