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.

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.

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.

• Backported 2.6.18 kernel from unstable.
• LVM/RAID will *NOT* work. Maybe I have to backport partman and dmraid to support them, but I haven't done yet.
• Since kernel 2.6.17, Debian kernel team merged SMP support to a single kernel. So don't panic even -smp kernel isn't installed. ISO image has -486, -686, -686-bigmem, and -k7.
• I haven't AHCI machine and I don't know PATA CD vs SATA HD problem still happen on 2.6.18. But I add a feature "atapi=true" boot option. When you append this option as the boot parameter, the installer will add the configuration to /etc/modprobe.conf.

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:

• Test bed for new software/methods that can then be deployed to lists.debian.org. In particular, we'd like to see EoC which would provide us with a few advantages over Smartlist which is currently in use on lists.debian.org.
• the ability to have temporary mailing lists
• Mailing list hosting for local Debian user groups
• Mailing list hosting for Debian related events and sub-events

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.

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.

A friend of mine with a 10 year old child wants his son to play less online Role Playing games and learn programming. In this kid’s free time, all he does is play computer games. At that age I was probably the same, though what made me a “programmer”? My friend is so frustrated with his son’s constant game playing, that he has limited his son to use the computer only in the weekends. I found this quite surprising, but I think I can understand his concern. I remember not coming down for dinner, because I wanted to play BRE (BBS door games) with my friends instead. Thankfully my Dad never threw out my computer out the window like he swore he would do at times. :) So now, my friend suggests that perhaps we could teach his child something about programming. Perhaps a whole group of kids. All armed with laptops. But, when I was that age, I don’t think I was very interested in programming for the most part. I had to be forced to write some logo and turbo pascal for school. And looking back at it, logo and turbo pascal seemed so much easier than the complex and multi-layered APIs (Web) I work with everyday. Ok, I do remember being enthused about:

• demoscene
• LAN parties with doom2 and quake

But both of these cultures seem to be on the decline. Or perhaps I am just out of touch? During boarding school I actually stopped having access to BBS/Internet so I didn’t really touch a computer throughout my A-levels. It was only at Bath University where I found myself, almost surprisingly, taking a Computer Science course I learnt about Unix et al. So I started learning Computer Science at University. I think people in Korea are surprised when I tell them I hardly knew about computers before I joined a Computer Science course! ;) Ok, so without driveling any more. Here are the questions for you to say your bit in the comments.

• Do you think it is worthwhile to teach programming (Computer Science) to a child?
• How can we get kids more excited / creative about computer science?
• And how should a parent deal with computer game addicted kid?

It would be great to teach on Plan9 or something simple, but I think kids would be more interested in graphics and sound. Bleh…

I was not a part of the devrooms team this year (like the last two years), Pascal did all the job! I was just a simple visitor and it’s a very cool position. Mark already bloged about the Classpath’s presentations, so you can find some interresting slides there. Saturday (25th February 2006) RMS Excellent talk about the patent. As always, Richard Stallman has great images to explain complex things. I still can’t understand all the GPL3 changes but I’ll try to read some more articles about it. Putting ‘Free’ into JFreeChart The presentation from David Gilbert was very cool. I did not know JFreeChart and it is really cool! This is a very big project and it makes very beautiful charts. I’d like to find some charts to do just to use it! Eclipse for GNU Classpath Development Tom Tromey did a fantastic presentation again. I already saw his presentations past years and it was still excellent. He already tried to explain me how to set up this Eclipse/GNU Classpath setup on IRC but I missed the “Don’t build automatically” hack. Everything should be on the Classpath’s wiki. Xen A presentation by Ian Pratt, leader of the Xen Source project. I heard about this project but I didn’t know that you could move an instance from a machine to another one! Amazing! Sunday (26th February 2006) I met Wouter in the bus but he lost his voice and asked me to introduce the speakers of the Debian room. I’m sorry for the three speakers I announced if it was not just as good as if Wouter did it. I wanna intend to the two conferences anyway. Women in Free Software I already wanna be at the talk of last year but I was in the Classpath devroom. Hanna M Wallach did a fantastic talk. I learned a lot of things and I know now that there really is a need of the debian-women project. I proposed her to put a phrase or a logo or something on the Debian-Java projects web pages and she seems to be pleased. Tonight, I went on #debian-women and it seems I did not understand nothing . So maybe I’d better do nothing about this unless I understand what I could do to help. Debian GNU/kFreeBSD port After the talk of Hanna, I introduced the kFreeBSD talk of Aurelien Jarno. I wanna listen to this talk because I completely don’t know *BSD… I’m sorry but I don’t know more. And I still don’t know the difference with Linux and don’t know why I should, as a simple user change to some *BSD port? Debian-Java Meeting After the kFreeBSD talk, I introduced the SLIND talk in the Debian Room, told Wouter that I go to the Classpath Devroom… and listen to the end of the talk of Christian Thalinger (CacaoJVM — the site was down when I tried). Sorry Christian, I just don’t understant these thing During the talk (or was this just after the talk of Robert about JamVM?), I went eating with Wolfgang Baer. We went back during the Christian’s talk. Then we had a Debian-Java talk (I should be writing down the summary of this meeting instead of blogging)… I’ll send an email about the meeting, don’t worry Future of Classpath It is the time when Mark ask everybody: What do you do? How can we help you? It’s a great social/technical time when everybody listen carrefully to everybody. It’s wonderful. Maybe it’s the part I prefer in free software. I must say that I read some mailing lists before joining some project and the ‘Classpath’ (and friends) projects were the one I prefer because of that respect. Then came the camera… A team came in the room to film us. They claim they were making a movie about Free Software. Funny I discussed a little bit with the woman that seems to be the director and she asked for my email (no, Hanna, it was not because she felt I am sexy , nobody tells me 100 times I’m sexy ). I told her I was not one of the main contributor but she just wanna talk about free software and understand how it works. Closing Talk: The Challenge of the GNU/Linux Desktop by Jeff Waugh Jeff Waugh is an excellent speaker, I really enjoyed the presentation. A lot of humour, a lot of facts, it was really an excellent presentation. But Jeff, I still do not understand the Ubuntu business plan. I’m not a native english speaker and I did not understand a lot of jokes and some responses. Back! I messed up with my GSM, lost my PIN number or someting I don’t know (I did it a thousand times!), I went to the shop today (Feb. 28) to be able to call again. I also went to the office and the alarm was on… I asked for the security guard (I did not want to take risks the day of my birthday: February 28th)… we found nobody but someone tryied to enter on Sunday. I’ll try to prepare some report about Debian-Java tomorrow. The report will be reviewed by Wolfgang and Michael and I’ll send it on the debian-java list on Saturday or on Sunday.

I woke up to a breakfast of pancakes, cooked by the wonderful riseorbleed. I don't know about you but waking up to a hot breakfast is heavenly. After some morning ablutions, we hailed a cab and along the way we chatted with the cabbie as I looked out the window. Luxor cabbies are really nice, every time I travelled with them, they had some interesting story to tell and big, broad smiles. Smiling is the way to fatter tips! The weather in San Francisco is supposed to be rather variable. You know how that is, rain one minute and then sun the next. Well, the entire time I was there, it was bright and sunny and gorgeous. San Francisco really put on her best to charm me and she really succeeded. I didn't think that postcard-perfect pictures were possible, but I saw them everywhere. I was happy to walk around without needing a winter coat. And everyone else smirked at how happy I was. Daniel seemed to have recovered from the previous night's revelry. His talk on delta was excellent because he's a very good public speaker. Which is good, because he gave two presentations at CodeCon. When I talked to him on Thursday night, he seemed a little embarassed at how successful delta had become since it such a simple piece of software. But people like GCC use it to fare down their bug reports to the lines of code that reproduce its bugs. Rob and Tristan sidled up to my bar and asked me if I could get them some juice. For their laptops. They were working on their presentation all the way until the last minute, which involved a drunken Tristan stumbling around on stage. Except that Tristan doesn't drink, so his imitation was quite poor. They were presenting Djinni, which is their implementation of a fast simulated-annealing algorithm that takes also pressure into account. Sadly, they didn't explain their algorithm but their talk was entertaining nevertheless. At lunch, Spider snuck me out of the building and she showed me around San Francisco. She pointed out the Eagle Tavern with a glimmer in her eye. I think she's trying to corrupt me. Or she's trying to pimp me out. Then we went to Stompers where she tried on some boots. We were stymied, however, by the fact that a very annoying woman and her husband were trying on every single pair of boots in the entire store. iGlance is a real-world video-conferencing and screen-sharing application that has some fairly good usability built into it. It also has a fairly sensible privacy model and does some NAT punching to boot. Although it's only got a Win32 port for now, it's free software so someone will fix it up. Sometime in the afternoon, the beautiful and fair wealhtheow came behind the bar and surprised me with a hug and a sandwich! I was happy with the random hug from a new friend, but the sandwich was wonderful. I had not eaten lunch on Friday so I was very grateful. She put a huge smile on my face. I munched on the sandwich while listening to the OASIS talk. This technology is a locality-aware server-selection resolver, which is pretty good for distributing servers around the world and finding the fastest one. They implement this as a DNS redirector so that lookups are transparent to normal Internet software. This made me feel a little bad for holdenk, whose SelfDirectedProject happens to be on a very similar topic. It does, however, validate his approach. maradydd's presentation about Query by Example was up next. She did a very good introduction to data-mining, which segued into her hack on PostgreSQL where you can specify examples of things you want to search for. That is not how SQL normally works, where you specify constraints. With QBE, you just specify things similiar to what you want, and things similar to what you don't want. I was chatting with Rob Pascual when I noticed Len lining up in the Q&A; queue. Suddenly, my ears perked up as I sensed something important was going to happen. So I pulled out my camera, stepped on some toes, and got into position. When it was his turn at the microphone, he started saying random stuff that wasn't question at all! Something cheesy like how Meredith had changed his life and how he wanted to be with her. Then he got up on stage and asked The Question. It was beautiful. The audience broke out into cheers and applause, except for the heartless bastards beside me. But who cares about them? This was such an awesome occurance that an interview was taped. After teardown, some people were going to head to a franchise Mexican restaurant. Spider insisted that I get real food, so we walked down to the Mission. We made a detour to Good Vibrations which is a San Francisco landmark if ever there was one. I swear that she's trying to corrupt me. Anyway, as we were walking out, I must have mentioned that I was from Canada. Because Cohen, a Torontonian, came out of nowhere and introduced himself to us. Well, what was I to do but to invite my fellow countryman to dinner? So we set off to find a Taqueria that served nopales. This failed since Californians don't seem to like eating cactus. Instead, we went to Pancho Villa where I ate enchiladas and salsa verde and guacamole and churros and I was so very happy! We bid farewell to Cohen after exchanging contact information and tried to find everyone else. Unfortunately, we couldn't reach anyone by cellphone, so we sat around dejected for a while. Then we realised that we could go to Annie's Social Club where an event was happening. This turned out to be a good and a bad idea. It was a good idea because we found everyone at CodeCon. It was a bad idea because Annie's Social Club double-booked us with bad karaoke! And then were quite rude when we complained. And then kicked out John Gilmore. So I just want to say that Annie's Social Club hates geeks and freedom. So Len hailed a black stretch limousine, we all climbed into it, invited some reporters along and moved the entire party to the XYZ bar. The XYZ staff were very awesome, accommodating an extra hundred patrons and getting an extra bartender. And they were very nice about it. Unfortunately, the bar was full, so I had to lead a bunch of introverts in the fine art of taking over an establishment. We walked in, started talking, I encouraged people to sit down in empty spots on the couches. They did a very admirable job of taking over the back. I got the stunningly adorable akashayi a seat and a drink, before I taked to the people sitting with us. They were a couple who had moved from Florida to San Francisco, and a man from New York who was quite the boor. The man in the couple knew the New Yorker and seemed quite embarassed about him. After twenty minutes of conversation, they excused themselves and bid us good night. This gave us plenty of seating space to talk about geeky things until the manager kindly kicked us out. I made sure Akasha got safely to her hostel and then took a taxi back to the guest room. It was quite the challenge to direct the cab driver, since I had lost the directions back, but I managed!

pasc: http://www.roombacommunity.com/. From what I’ve seen, they’re neat little machines.

I never thought I would see the day where I would actually find a vacuum cleaner cool. So... Who's going to be the first to put Debian on it?

So I got pet peeved by Carlos Laviola in relation to by recent pondering about how MacOS X's SSH agent starts up on login. Perfectly reasonable grounds for complaint. I have had people contact me in relation to blog posts in the past, so it's obviously not impossible. People know I'm a Debian developer and can put two and two together and wind up at db.debian.org. Anyway, I'm the first to admit that my blog probably has too many of the Weblog Usability Top Ten Design Mistakes (something for me to work on). To date, I've been avoiding plastering my email address on my website because I didn't want to get it harvested. I try and use a per-list email address for this reason as well, and I haven't enabled blog comments because of comment spam, and because I haven't been clever enough to implement comments with Blosxom full stop. So I started getting an idea for reversibly encrypting my email address on my blog after reading about Hashcash for Wordpress the other day. I first started playing around with the Vernam cipher in High School, when I wanted to easily reversibly obfuscate some data for something. I'd read about this cipher in a magazine or something and seen it implemented in Pascal (it's not exactly hard). So I happened upon the idea of encrypting my email address with the Vernam cipher. Turns out another chap's already got a page for encrypting and decrypting on the fly with JavaScript. It even generates the JavaScript for putting in your own web pages. I had to use a different key to avoid getting dollar signs in the encrypted string, as this confused the tripe out of Blosxom (and me for a while when I tried to figure out what was going wrong). Then I thought it'd be nice to explain to people who had JavaScript disabled what they might be missing out on, so I fiddled around with some DOM stuff, and had some text get displayed if JavaScript was disabled. When JavaScript is enabled, this text is replaced by the decrypted text. So of course, like the Wordpress Hashcash, this is largely relying on the inability of spam bots to grok JavaScript. Once they can, this obfuscation technique is all for naught. Meanwhile, you can email me bit more easily now if you get the urge. View the source of my blog for an example of the implementation.

Finally, I can drop freepascal. It turned out to be far more effective to rewrite things in c++ (like, do a module in a day, while I've been fighting freepascal for a week, before I worked around all quirks and bugs). Maybe life does not suck that much, after all...
