Martin-Éric Racine: ALSA pitfalls ... and a bounty ... or two

Daniel Jacobowitz writes about problems he's having getting proper ALSA support for his desktop computer. Boy, does that sound familiar! I myself have three computers that are partially or totally unsupported on ALSA:
  • Apple iMac rev.D a.k.a. 333MHz G3 tray-loading iMac. Partially supported by snd-powermac, except that some controls are inverted and other controls just plain don't work. Probably something as simple as the wrong offset in the bitmap used to select the control on which to act. Bug filed in the ALSA BTS. No reaction. Anyhow, sound support for Apple products is being migrated to snd-aop, which was written from scratch using a modular architecture that enables easily adding support for new sound chips. Nice idea, except that no effort is being put towards supporting pre-G4 products... Back when Ubuntu appeared on the Linux scene, Mark Shuttleworth agreed to pay a 500$ bounty to whoever made ALSA work on all PowerMac variants. Nobody took it, as far as I know. Those who are interested in taking on this challenge might wanna check my wiki page for our summary of the ALSA PowerMac situation.
  • HP 9000 series model 712. Recently supported, thanks to someone on the PA-RISC Linux mailing list having a go at coding it. Never merged by upstream ALSA, though. It's been a while since I gave it a try but, last time, only output worked.
  • AMD Geode SCx200. There is no snd-scx200 driver at all. Bug filed in the ALSA BTS. The issue of sound support on early Geode products was also mentioned on the Linux kernel mailing list, during the big OSS cleanup discussion so, at least, some people are aware of the issue. It so happens that the Geode SC is used in a number of popular embedded boards, such as the Soekris and yet, nobody tried porting the old OSS drivers available on AMD's Geode driver source page. Odd.
As we can see, there's plenty of ALSA support remaining to be coded, ported or cleaned up, and some people are willing to pay for the results. Who's gonna grab it?

Isaac Clerencia: Anti-bullfighting demo

More than a thousand people took part in the anti-bullfighting demo that every year takes place in Zaragoza. (Spanish) For those who are not familiar with bullfighting, it’s basically a Spanish shameful tradition, where six bulls are released one at a time to a bullfighting arena. There the bulls are tortured to death, first they’re stabbed on the neck by horse-mounted lancers, then they got planted in their back several harpoon-pointed sticks, and after half an hour of torture and agony, the bullfighter definitely murders the bull with a sword. Does it sound disgusting, cruel and sadist? It definitely is, and I’ve skipped the worst details. (yeah, I’ve got sick just writing this) We gathered at a square near the bullfighting arena, and then we headed towards it shouting stuff like “torture is neither art nor culture” (as bullfighting defenders usually say that “bullfighting is a central part of Spanish culture”), “murderers”, “torturers”, “sadists”, “you’re cavemen, evolve!”, “if you wanna see blood, slit your wrist” or “you should be ashamed of how you are raising your children” (to people who brought little (5 or 6 years old) children to the bullfight arena). The demo lasted about two hours and was completely peaceful, which is a great thing IMHO, as it clearly shows which side despises violence and which one loves it. There have been several good news for the anti-bullfighting movement last years, like several Catalonian towns declaring bullfighting illegal, Barcelona declaring itself an anti-bullfighting city (although it doesn’t have the legislative power to really ban bullfighting), demos in lots of cities and increase in people attending them. If Bullfighting seems doomed, but we still will have to push for a few years to really bury it. Even if you are not Spanish you can still help abolish bullfighting by taking part in anti-bullfight demos in front of Spanish embassies (there were 17 of them this summer), boycotting travel agents that promote bullfighting, …

Daniel Jacobowitz: ALSA: Disasters, frustration, hacking, progress, and education

I have had, ever since I got my current desktop, been frustrated with ALSA support for it. The machine is an Shuttle SN25P (with ice1724 onboard 7.1 sound card); it's otherwise very nice. I've had it for a bit over a year. When I got it, I lost several long weekends to hacking on ALSA and peering through asoundrc files, gstreamer and gnome-control-center source code, and other such things. There were two basic problems. One was that no matter what I did, I couldn't get the back speakers to play independent channels. Generally they mirrored the front speakers. The other was they adjusted volume based on the headphone mixer, rather than the master mixer - especially aggravating because muting the master mixer left my music still pouring out of the rear speakers! I filed a bug in the ALSA tracker, but didn't get much feedback, and eventually gave up. Last week, someone else seconded the bug. A helpful fellow responded and pointed us to a couple of basics, like the ALSA datasheet archive (very handy, since as far as I can tell a lot of them aren't available elsewhere, at least without NDAs). We spent some time poring over those. One of the interesting things I learned this weekend: there's a bunch of independent chips involved in onboard sound, in my case three. One seems to do communication between the computer and the analog-digital convertor, another handles the actual conversion (AC97 compatible in this case), and a third (I think...) handles the remaining two channels for 7.1 support since the second one only seems to do six. Digression time. Unfortunately one of the things he asked us to check was physical connections between the chips, and whether there was an onboard EEPROM... and somehow, in lightly applying enough compressed air to dislodge the dust, I got something wedged into the fan of my video card. Which began making a horrible rattling noise. And then when I attempted to clean it, I made it even worse. So at this point in my Saturday afternoon I had to go out and buy another one. The new one is marginally crappier than the old one, which was also pretty cheap, but the new one has the advantage of not needing a fan at all. Digression part two. While I was at the store, I picked up a Slug. I haven't unboxed it yet or gotten a drive for it, but I think I will in a week or two, and see if I can pick up some of Martin's excellent work in running Debian on one. I see that the IXP ethernet driver isn't working at the moment, maybe I can give Lennert a hand... At this point it was clear ALSA had eaten my weekend. So I came back to finish the job. The other reporter of the bug noticed a very interesting bit in the manual for the VT1617A (Via-manufactured AC97 codec) - which affected volume control and routing for the rear surround channels. I poked around in the kernel driver for a while, and discovered that the similar VT1616 chip exposed that bit as an ALSA mixer control (boolean switch)! So, wiring the two together was the next logical step. And suddenly I'd made a world of progress. I could hear things out the back speakers. Apparently - as far as I can tell anyway - no one has good solutions to this problem. I fumbled around with it for a while, wrote two more ALSA patches, and got manual configuration to use a software volume control (the "softvol" plugin) and mute switch which govern all channels. But I'm taking a break from that while I fish around for how this works on other chipsets. It's so immensely awkward that I can't believe there's no standard solution. I mean, is wanting your volume control to affect all your speakers such a rare thing? Anyway, this paragraph summarizes about six hours of beating my head on the wall. Most of this was at the asoundrc format, which is immensely picky, underdocumented, and seems like it really oughtn't to be needed at all. But apparently it is. During the course of this I got to learn how different applications decide which volume control to use, which was exciting in an exasperating and insanity inducing sort of way. You see, ALSA exports basically everything on the card as a "mixer control". There's some things which recognize volume controls by name, and some basic sorting by usefulness. xmms allows you to select any one control to use for its volume slider, which is nice. The GNOME mixer applet allows you to select any arbitrary _set_ of volume controls for the panel applet, which is even nicer. But it's at this point that, both last time and this time, I gave up in general rage. You see, the mixer applet is completely disconnected from the other and more useful way I deal with volume - the hotkeys on my keyboard, which GNOME also handles. But those go to gnome-settings-daemon, and a bunch of code labelled "acme". And this just adjusts the volume on the track which gstreamer (the GNOME audio management libraries) have marked as "MASTER", and that's done based on the order ALSA supplies the controls, which is done by a name-based sorting deep within the bowels of the ALSA library (it's in mixer/simple_none.c). And if you have two with similar enough names, it slaves them together. And nothing has a higher priority than the hardware supplied "Master Playback" controls. The best I could manage was to get the software volume control listed right after the master (in which case it wouldn't get adjusted at all), or adjusted in lockstep with the real master channel (which causes the front speakers to drop at a different rate from the rear speakers, messing up depth). Like last time, this was the point at which I gave up for the weekend. But this time I've learned a lot more and made a whole lot more progress! And written more of it down, so hopefully I have to rediscover less of it next time. I really was going to do a bunch of other things this weekend... but it just didn't happen.

Martin-Éric Racine: Linutop - Internet for the masses

I promised last week that I would be telling more on October 1st, about the mysterious Project X that I had been sporadically blogging about over the last few months. Better late than never, so here's the story: Casablanca I met Morocco-based French entrepreneur Laurent Bervas via his blog in January 2006, while looking for countries nearby EU with a promising ICT market, because of growing obstacles in getting work in my field, due to my not being an EU national. By the time the situation had reached the ridiculous extreme that friends were continuously loosing juicy recruitment bonuses, simply because their employer's HR department had issues with hiring non-EU nationals despite EU policies that clearly favor foreigners married to an EU national I figured that I ought to do something creative and see which of the countries bordering with EU might offer interesting opportunities. Laurent was blogging about all the exciting opportunities he kept on seeing, since he relocated to Morocco to conquer the high-end Real Estate market. One day, he wrote about Morocco becoming a rising figure in the outsourcing business for the Francophone market, which prompted me to contact him. After a couple of weeks of discussion, he cautiously dropped his idea for a niche market he had spotted: a simple Linux-based set top box to surf the Internet. He then asked if I would be interested in developing it and in launching a startup with him to promote it. I gladly accepted. Startup That's when Laurent decided to introduce me to an old friend of his, Fr d ric Baille, who spent several years at Compaq, culminating with a role in the team that launched the iPaq. Fred's help was instrumental in defining the market positioning of our product. Laurent and I discussed the product features at length over IM and immediately agreed that the OS would be based on Free Software. That left the hardware part unresolved... or so did Laurent think. Years ago, I briefly worked in the management team of an Estonian data security startup. This gave me the opportunity to network with several movers and shakers of the Estonian ICT. Among them was a promising ASIC and industrial design startup that produced really cool Thin Client hardware. The answer to our hardware needs, I figured, could easily be fulfilled by them. My idea of contracting the hardware to Estonia was initially received with skepticism, so I made a simple proposal: why don't we hold the inception meeting in Tallinn and meet with the potential hardware supplier at the same time? Fred and Laurent accepted, so we spent part of April 2006 there, with me acting both as their friendly tourist guide and as the middleman for the introductions. Fred and Laurent immediately fell in love with Tallinn's designer bars, omnipresent WiFi network and blond-a-plenty. Most of all, their visit at our potential hardware supplier gave them the answers they needed: Estonia is IT. Overview The hardware we selected is built around the AMD Geode LX, a nifty Pentium-compatible single-chip computer. It comes equipped with VGA output and four USB 2.0 ports, along with high-quality audio via 1/8" input and output jacks, plus a built-in encryption engine. We added 100baseT Ethernet connectivity (with provision for other networking options) to that, to complete the platform. For the software part, we used ingredients from Debian's Etch release, focusing on a configuration that would enable easy access to the most popular applications for home and small business use: Instant Messenger (Gaim), Multimedia player (Totem), PDF reader (Evince), Web browser (Firefox), word processor (AbiWord). The result is this: Press Coverage The editorial team at IT-Neeger (an A-level Estonian ICT blog) immediately scooped the story [in Estonian] and it produced such a strong response that the traditional Estonian media contacted the IT-Neeger team to write a feature article (stay tuned for details). The local Slashdot, Minut.EE, also reported [in Estonian] on the IT-Neeger article. Thus, myself and Laurent Bervas spent the better part of this week being blogged, interviewed and podcasted by a variety of Estonian and French publications, which is how I only got around blogging this bit tonight. Marketing Contrary to our competitors, we fully intend on keeping this platform open, so our initial market will actually be Free Software developers with a penchant for innovation. As such, our first 50 units are exclusively intended for interested developers who want to improve upon our initial idea and participate in defining the final product. Inquiries are welcome!

Adam Rosi-Kessel: Absurd Copyright Law Case of the Day

I’m visiting my parents’ house in Vermont, where they finally got cable after the provider agreed to dig up the ground and run a mile or so of cable to their house in return for a two year subscription agreement. (I think after two years the cable company will almost have broken even on the cost of the installation). Having been absent myself from the cable world for some time, I am impressed by the variety of interactive and “on demand” options. My parents’ low-end package includes dozens of free on-demand movies and music videos, as well as built-in easy-to-use tivo-like functionality. The on-demand music videos show one brief ad before the video — it seems the tradeoff is that if you are really going to watch the ad, they can get more money and show you fewer ads. (Or, maybe I’m wrong — if it’s one ad per video, I suppose that would be more ads, but it feels like fewer because of the “on demand” nature. I guess it’s a perceptual trick.) Anyway, getting to the title of this entry. Anybody in the field of intellectual property these days has got to find Weird Al Yankovic’s music video for Don’t Download This Song (warning, myspace page, authorized by Weird Al!) (or, here) (warning, YouTube page, also authorized by Weird Al!) at least a little amusing. If you haven’t watched it, see it now. The opening verse goes like this:
Once in a while maybe you will feel the urge
To break international copyright law
By downloading MP3s from file sharing sites
Like Morpheus or Grokster, or Limeware or Kazaa
But deep in your heart you know the guilt would drive you mad
And the shame would leave a perminant scar
Cuz you’d start out stealing songs, then you’re robbing liquor stores
And selling crack and running over school kids with your car
On the cable video-on-demand channel, however, the names of all the filesharing services (Morpheus, Grokster, Limewire, and Kazaa), are all replaced with beeps, as if they were vulgarities unfit for broadcast. Or cable. If you had never seen the video online, you’d actually be likely to think this was another Weird Al joke — that he can’t even sing the names of (the mostly now defunct) filesharing services publicly. But I’m pretty sure the video was censored by the cable provider or distributor and the irony is wholly unintended. There are a couple of possibilities here. One is that the distributor was trying to avoid inducement liability under the Supreme Court’s decision in MGM v. Grokster. Could a funny song about filesharing actually meet the inducement standard? I sure hope not. The other possibility is that the distributor just found the references too abhorrent to leave in — basically the equivalent of the seven dirty words banned from broadcast TV and radio. Either way, if Weird Al were dead, I’m sure he’d be spinning in his grave. We’re lucky he’s still kicking. (“case” is kind of a misnomer for the title here, but is included for consistency).

Biella Coleman: ABILIFY THIS

Yesterday I was catching up with my magazine reading at Chapters (the Canadian equivalent of Border) when I came across an ad for a drug ad for bipolar disorder that struck me as slightly different less euphoric, more cautious to be exact compared with the ads that have been bandied loosely in all sorts of magazines in the last decade in the US. The ad was for a drug called Abilify which must be some verbal riff on Ability (no?) and there was a very clear pronouncement on that ad that admitted they had no idea how the drug even worked. It went like this: ABILIFY may work by adjusting dopmamine activity instead of completely blocking it and by adjusting serotonin activity. However, the exact way any medicine for bipolar disorder works is unknown. I find this interesting because its tone seems to depart from other ads that seem somewhat more confident (or if they were less so, it was probably kept in the fine print). But when I went to the webpage, this caveat was a little harder to find, as it was a few clicks away within a page entitlted The Brain, Bipolar I Disorder, and ABILIFY . It provides a “handy” pictoral representation of what may be going on with your brain with bipolar disorder/treatment. I found the series somewhat odd and amusing, especially the one that used a magnifying glass to see” all the neurons and nerves or whatever they are in your brain. update: so you know, the US and New Zealand are the only 2 countries that allow drug direct to consumer advertising so I am not sure what the ad was doing in this magazine. It was American magazine but in Canada. I would think they would make them get rid of ads like that. Anyone know why it can slip through the border like that?

Gunnar Wolf: About Google Reader

Ian: I have to agree with you - Google Reader rocks. So far, I've been quite reluctant on putting more personal information in other entities hands than what is necessary - specially when those entities are, as Google, expert in exploiting whatever they learn about you. Call me a paranoid, a privacy freak, or whatnot, but after fooling around a bit on Orkut, I decided to withdraw all of my participation there (and never engaged on explicit social network sites ever again - Of course, my participation in several mailing lists is tracked by many Web searchers, and I'm sure I'm well categorized in non-explicit social networks - To say the least, my GPG key is in the Debian keyring ;-) ). I never got a Gmail account and hope I'll never have to - After all, gwolf.org gives me way more than 1Gb of space, is easily accessible and searchable (by me and only by me)... Why should I worry with that?
But, yes, Google Reader gave me something I didn't ever before have: The ability to read my RSS feeds from wherever, from whatever computer, without worrying about synchronizing. For the first time ever, I found my cell phone's uncomfortable, tiny but usable Web browser good for something - whenever I cross the city, I can do it reading news or my friends' life updates. That's quite cool, and that's the only reason I'm ditching Liferea.
But unlike you, I would prefer a more mailbox-like system on Reader. And having to use non-free software sucks, as there is no way for me to change this but to bitch around :) Why do I like to treat my feeds as mail folders? Because there is certain coherence between them. If I just "read all", I get a strange mixing of unrelated items. However, in Liferea, I went through each of my feeds, in order, unless (of course) I decided to jump to another one. And I can do the same in Reader, by clicking on each individual feed with pending items... But it's a manual operation, and those should be avoided. Liferea does support acting as Google Reader, when you click on the "all unread items" virtual folder, but the default style is just the other one.
Anyway... I know that overloading Reader with everybody's preferences is not an option. I know I am not like most Google Reader's users, and it sucks. I'll have to get used to the more regular style (or write an aggregator for myself and host it at gwolf.org or such), but I'm too tied with other stuff to give it a go. :-/
Besides, I like to complain.

Biella Coleman: My Reading

So people may be wondering, How does Biella pass her time in the vast, desolate Canadian north? Thankfully there are many things to do in Edmonton proper, but I have delved quite a bit into reading so I thought I would take a break and give small reviews of the books I have read or am reading as they are all quite good. I am trying to be more systematic about my reading habits so I am back to using citeulike. I am adding anything new I read and then as I go back to I have already read (for articles), I am adding them to the list also. I hope this pays off in the future! I started the reading bash with a book that was recommended to me over a year ago while I was still in Chicago: The Fugitive’s Property: Law and the Poetics of Personhood as it deals with the bread and butter of my own work, intellectual property, liberalism, market capitalism, and American history. I found the introduction enlivening and was sufficiently interested to continue on. I think there is not a lot of innovative work in the field of intellectual property (only because it has been covered very well) and to bring together slavery/the fugitive person and intellectual property under the same analytical lens, seems productive. Best looks at how the legal treatment of the slave and that of IP, hold striking parallels for their highly fugitive (formal) nature, driven and intensified by the legal/market framework that makes personhood into property. There is a lot of good stuff in there (including a fantastic discussion on legal positivism) but in the end, the labor it took to sift through some really obtuse prose was too much for me. I can’t remember the last time I languished under the heavy weight of language that was far too ornate and under sentences that just lacked clarity. This was compounded by the fact that he assumed you knew a fair bit about slave history, which I did not. My drive also escaped me and while I hope to return to it later, I took a break and turned to more readbale material. After such heavy linguistic ornateness, I needed an antidote, QUICK, and I knew exactly where to go: William Sewell and his book I had on my shelf also nearly for a year: The Logics of History. Along with being a first rate historian he is like that black instrument popularized in the 1980s by the likes of Herbie Hancock, and Brian Eno, he is a synthesizer with an amazing ability to write clearly. Being the synthesizer that he is, he is skilled at connecting the dots between various theoretical topics like event, structure, and agency, making the theoretical implications so crystal clear you feel happy to have entered into a field (the social sciences that is) that feels awfully arcane and pointless at times. I left Stehpen Best, which was like leaving a cluttered medieval castle and into a simply decorated room filled nothing with good theoretical feng shui (I think about writing in spatial terms more than ever). He just makes reading fun, even when the topics can be less than enthralling. Many of the essays were published previously and I had read a number of them, such as his famous essay on structure and agency. What I appreciated along with the great writing, was that he takes serious the question of plurality of social life within the net of various social, economic, political determinants. So while he assumes the existence of structure (and turns Marshall Sahlins to establish), he also is quick to show that structure, like a cultural system, can only act as partial (and unexpected determinants of social life) because of the existence and presence of events (which is really Sahlins great masterful point) but more importantly because of the plurality of structures… This was perhaps on the the central motifs in my dissertation; while I placed hacking within the cultural lineage of liberalism, in no way is this the only cultural system that hackers operate through and with; they move through a cultural domain more intrinsic to their own praxis, not to mention other systems of value that reverberate more widely among the digerati… And it is this movement between social positions that allows for forms of reflexivity and social change. I primarily used Bakhtin to make this point but now I got Sewell to add to this mix. Here is a nice passage from the book that makes this point:
I would argue that a multiple conception of structures would make subjects cultural creativity easier to explain. If the cultural structures by which subjectivities are formed are multiple, then so are the subjectivities… Because persons, symbols, and objects of cultural reference overlap between structural realms, structurally generated rules, emotions, categories, and senses of self can potentially be transposed from one situation to another. Indeed, if actors commonly have the experience of negotiating and renegotiating the relationships between noncongruent cultural structures, it follows they should have some intellectual distance on the structural categories themselves, that they should be able to view one set of cultural categories from the point of view of others that are differently organized, to compare and critizise categories and categorical logics, to work out ways of harmonization or odering the seemingly contradictory demands of different cultural schemes. A multiple conception of structure, consequently makes human creativity and reflection an integral element in the theory of history, not a philosophically prior metaphysical assumption. p. 213
And here is a more engaged review that is a little more critical than my very short comments. As part of a reading group organized by my tireless supervisor, I am also reading The Cultural Locations of Disability written by two of the most prolific scholars in the field, Sharon Snyder and David Mitchell. Since I am a novice in field it is hard for me to judge the two chapters we have so far read but it is a total total total treat reading a book slowly with a group of other folks from a vast range of departments. So far I appreciate the larger arguments presented in the introduction. For example, they point to two broad categories—capitalism and modernity/enlightenment– as driving forces in a new wave of obsession with the disabled. So while capitalism’s insistence on measuring the worth of humans through an abstract and actual ability to labor, marginalizes those who cannot offer their constant labor power (and makes them an “odd” cultural object), modernity–in its desire to march forward to the mysterious plane of progress, offers a technological promise to eradicate what it designates as deviant or primitive. As they nicely sum up: In a culture that endlessly assures itself that it is on the verge of conquering Nature once and for all, along with its own primitive instincts and the persistent domains of have-nots, disability is referenced with respect to these idealized visions. As a vector of human variability, disabled bodies both represent a throwback to human prehistory and serve as the barometer of a future without deviancy. p. 31 I, think, however, they should have also included some discussion of liberalism, which in many ways, was the legal and philosophical engine that helped to naturalize capitalism not to mention it also offered a vision of person, in which self-development, expression, and discrete autonomy was deeply cherished. Seen in this liberal light, disability becomes also a type of tragedy that can be resolved though new technological interventions they discuss under the guise of modernity. I have just started Michelle Murphy’s Sick Building Syndrome and the Problem of Uncertainty: Environmental Politics, Technoscience, and Women Workers, which promises to be quite a tour de force into the contentious politics of uncertainty and the play of perceptibility and imperceptibility that surround one of many many syndromes sick building syndrome that now are part and parcel of the medical and patient advocacy field. Along with this I read and finished Andrew Lakoff’s Pharmaceutical Reason: Knowledge and Value in Global Psychiatry, which will make for great teaching, and has one of the nicest discussions on the way in which psychiatry’s insecure status among the other medical science was one of the driving forces toward embracing the new scientism of the 1980s that coincided with new more general neoliberal trends. Another nice move about the ethnography is that he was able to clarify some of the trends and rationalities of American and European psychiatry by examining how it was received and resisted among more psychoanalytical Argentinian therapists. Very classicial anthropological lens in that sesne. Finally I am in the middle of Play Money: Or, How I Quit My Day Job and Made Millions Trading Virtual Loop and I will say more about it when I am done, which should be soon as I am tearing through it evern night. I have been waiting for this book for a long while now because Dibbell is part of that trinity (Steven Levy, Bruce Sterling, Julian Dibbell) that offers some of the best writing on hackers, the internet, and virtual worlds. And this book continues in that tradition of providing a fantastic read, a vivid ethnographic picture of the topic at hand, along with key insights into the nature of economies, money, and plau within (and outside of) virtual landscapes. What I respect about Julian Dibbell is that he took a long time to get this book out. He started the research in 2003 and then spent a few years writing up. I think there is a lot of pressure to get any material or book on “virtual whatever” out there as quick as possible but for the most part I think that is a mistake. You need to let these things brew a long while or else they won’t acquire that taste of a finished product.

Ben Armstrong: Ichthux and Ubuntu CE: Why two projects?

Barbicane asked me the other day: “Why Ichthux and Ubuntu CE? Why not consolidate efforts?” As much as I’d like to see Ubuntu CE succeed, I believe they are headed down a path that will make it difficult for them to survive if they continue. In this thread (see Google cache since the forums seem to be having problems today) Jereme severely understates the differences in development philosophies that keep us apart. One key difference is more fundamental than just using metapackages instead of scripts. As I wrote about earlier, the approach Ichthux has chosen is to be a Custom Debian Distribution (CDD), working within Debian and Ubuntu to configure those distributions for the needs of Christians to meet their various needs. This is incompatible with CE’s approach, which uses scripts to tailor an Ubuntu system. This approach risks violating the integrity of the packages being modified, and makes each system upgrade an adventure for the user. What you end up with cannot truly be called an “edition” of Ubuntu at all, but is more accurately described as an Ubuntu derivative. Derivatives are not easily sustained because they are always struggling with staying in sync with the parent distribution. Ubuntu itself is a derivative, but it has an impressive amount of infrastructure with a lot of manpower behind it to ensure that the branching and merging process doesn’t get out of control. I don’t see how the much smaller Ubuntu CE development team will manage to accomplish anything significant using their current approach without being crushed by the maintenance costs of their customizations. Another difference, perhaps more readily apparent to end users, is what’s included in each distribution by default. While CE has chosen the Gnome desktop, Ichthux has gone with KDE. With each new release of Ubuntu CE, it seems what is stressed the most in their release notes is “what’s included”. Well, I just can’t see how that’s terribly important. Debian and Ubuntu both have a vast amount of software available, and both make it easy for users to make choices. If a user wants to add another application, it’s often just a few clicks away. It’s not nearly as important to have these installed by default as it is to ensure that the packages we do include are as solid and well-integrated with the system as possible. To this end, Ichthux makes use of its Debian and Ubuntu developers to ensure that each package included is kept in good shape from release to release. This means addressing bugs and wishlists that matter to our users, improving those packages not just for Ichthux, but for Ubuntu, Debian, and where those fixes flow back upstream, the broader community of Christian FOSS users everywhere. This is the real work of Ichthux: not just the production of a livecd, nor merely tweaking the default selection of packages we include from one release to the next, but to be actively involved in the Christian FOSS developer and user community. Our greatest successes will not be in the degree to which we differentiate ourselves from other Linux distributions, but rather how well we’re listening to what Christian FOSS users are saying they need, and how broad we can make our solutions. We can’t afford to be a niche distribution working off in a corner on our own pet project. That would be a terrible waste of our energy. We’re dreaming big: we want every Christian Linux user to be able to benefit from our work.

Ben Armstrong: TODO or not TODO

I’m reviewing my next actions: dozens of worthy projects waiting for me to do. But I just can’t seem to get moving on any of them. What’s keeping me back? What is so hard about getting things done? Especially with respect to the more rewarding tasks on the list, it’s a mystery that I fail to act. It should be easy. I’ve fretted over this problem for years, yet I’m no closer to an answer today at age forty than when I first discovered my dubious skills many moons ago as a procrastinator extraordinare. Surely all that I need to do is stop worrying and just act—act, and continue to act until to get things done is as natural as breathing. Oh, so simple! So easy to say! I fear I am caught in a cycle of anxiety and inaction that defeats me before I even begin. Faced with my list of next actions, I inexplicably feel anxiety about it with something like the force of physical pain. I balk. I seek out some numbing diversion to get relief: anything but whatever’s at the top of my list. But I know I mustn’t nurse this fear, or it will grow. I will not escape by focusing on how hard it is. So I resolve to nurture hope, to act and not doubt. TODO: Pick any next action. Do it! Repeat.

Ian Murdock: Dunc Tank, Debian, and leadership

I’ve been asked by numerous people for my take on Dunc Tank, the latest “conspiracy” to roil the Debian waters. (Summary: Dunc Tank aims to raise funds to pay Debian developers to complete certain key projects, such as ensuring the next version of Debian, etch, is released on time.) My take is simple: The kind of childish sniping that has taken place over the past few weeks (which, as usual, seems to come from a small but extremely vocal corner of the community) does far more harm to Debian than any perceived monetary “taint”. It’s no wonder “the enterprise” doesn’t take Debian seriously. If anything, I’m encouraged by what I’ve seen lately, namely that Debian finally has strong leadership that’s willing to take necessary steps without fear of offending the mob of the few that often paralyzes these kinds of projects. Bravo, AJ. And keep at it. It takes a steely sort of person to stick their necks out like this, but strong leadership is absolutely essential to the success of any project, open source or otherwise. After all, success doesn’t just happen at random.

Russell Coker: Virgin - no free water and renewable energy

When returning from Ruxcon I took a Virgin Blue flight.

The Virgin web site has a FAQ with the following advice regarding DVT:
Drink plenty of water and other fluids during and after the flight, limiting alcohol, tea and coffee.

However Virgin provide no free water on the flight and charge $2 for 350ml of water! This is a strong incentive to buy caffeinated drinks and/or alcohol, after all if you are going to pay then you want something better than water!

They should provide free tap water as a basic health measure.

On the positive side there was an interesting article in the Virgin Blue magazine about alternative sources of fuel. It covered bio-Diesel (renewable and produces less toxic smoke), and producing Diesel from waste plastic (saves space in land-fill as well as providing fuel). It wasn't as technically detailled as I would like and it didn't mention some of the methods being developed for producing Diesel fuel from algae or the work on using bio-fuel for jet aircraft (which would be appropriate for an airline magazine).

But it's a good start, hopefully some travellers will learn that there are environmental problems and ways that we can fix them.

Zak B. Elep: Unexpected

There was no power again at the office today (thanks to my boss for sounding me while I was laying in bed ;) so I had a pretty free day today. This is the first of my Unexpected Series of Events (although, in retrospect, this is somewhat expected since we did lose power at the office yesterday, giving credence to Clair’s story…) So I spent a little more time in bed, trying to get sleep; but my Mom got me ony my feet, calling via landline all the way from Daet, which just got its power restored a few days prior. She told me that my Tita Mendy will be arriving tomorrow, and she’ll be carrying some of my things too. That’s the second Unexpected. After that I left the house to deposit my second paycheck from work and payment for my second semester at school. A quick trek back home for lunch, and a few pages of Even Grues Get Full after, I went to Robinsons Place to check mail for free (well, not really free since I usually pay for my cup of Java to have a reason for taking a table.) As I’ve come to expect of freebies, free WiFi in Robinsons is rather limiting, as it appears to only allow HTTP ,S connections (yeah, no Yahoo! even for the unenlightened masses!) The bandwidth, in fairness, is fairly decent, allowing for a good audio or video stream to pass through without much lag (as long as its from HTTP ,S .) However, today’s service was extra crappy, as it appears that the WiFi DHCP server went down, and I couldn’t acquire an IP address. It wasn’t much of a problem for me, though: last weekend allowed me to spend a lot of my time hanging out in the place as it was the only place nearby to have seemingly continuous DC power (the storm that passed over pretty much knocked down normal AC power everywhere,) and also gave me an excuse to explore the WiFi network, letting me know such minutiae as the right IP address block and gateway Robinsons Free WiFi used. Hence, even without DHCP, I was able to configure Perlis to connect via a statically-randomly-chosen-by-magic-255-ball IP address. This wasn’t Unexpected. What was Unexpected was what happened next: as I was surfing the Web, I noticed that the other folks nearby were having difficulties accessing the free WiFi; of course, they didn’t have the information (that I had known by simply being observant) that they needed. Nearest to my table were a couple of Korean-looking foreigners and a doctor-looking guy inquiring each other if they were able to connect. I went near them and asked them about it too. Yeah, my deductions were correct; the foreigners (hello, Emma and Jay) were Korean students learning English, the guy (hello, Charlie Atienza) was a dentist, and all of them couldn’t connect to the Net. Windows was choking up on them, since it could not acquire an IP address. So, needless to say, I came to the rescue, and within a few minutes (which included trying to change the Korean’s locale settings to Engrish, which we eventually gave up, and forcing me to hibernate Kubuntu and booting to Windows just to find the right Network Settings menu, duh) I got them to have a working, albeit laggy, internet. I couldn’t get Charlie’s laptop working though, since it seemed to suffer another problem althogether :/ At any rate, meeting new people over this problem was by itself quite Unexpected, but that wasn’t the only thing: Charlie noticed my Kubuntu desktop earlier and recognized it immediately as open source. It turns out that Charlie have seen FOSS operating systems in action via Knoppix, and he knows Dr. Alvin Marcelo (of CHITS fame) and Eric Pareja, and is also quite involved in bioinformatics too. Small world indeed! =) I guess having no power at the office makes for a good adventure, after all. Well, yesterday was quite an adventure in itself (Clair can tell you all that, and more :P ) Today, however, was pretty much very Unexpected, and indeed I’m thankful that so many surprises come my way. The last Unexpected: I forgot to update my phone number on the calling cards I gave away today. :P Oh well…

NOKUBI Takatsugu: i18n discussion with Warren Togami

Now Warren Togami, the founder of the Fedora Project, is in Japan. And today I and some Japanese FLOSS developers (includes Kenshi Muto) are going to discuss with him. The last year, he has come to Japan and already discussed about i18n with many people, so today's addendants are a few people. Anyway, I hope the discussion will improve i18n environment in the FLOSS world.

Marc 'HE' Brockschmidt: Why I keep working on Debian

I haven't blogged in a long time, so I probably should drop some thoughts here to show that I'm still around.

In the past few months, I have been able to dump some of my work on other people by orphaning some packages and getting Christoph Berg (Myon) to do Debian Front Desk work.

To compensate this loss of tasks, I became a member of the release team, so the recent discussions about funding release managers should probably interest me, but I fear the threads on debian-private, -project and -vote have only made me sick. The number of people who have been childish, unjust and simply weird is enormous and would be a good reason to leave Debian altogether, something which I considered a few times over the last weeks. I would surely quit a job where co-workers hate each other that much, so why should I do this to myself in my free time?

Interestingly enough, actual work for money has shown me why Debian is something that should be supported, even if the mailing lists are full of posts from idiots. I had (and have) to work on OpenBSD for a customer, porting the recent release of Gnome 2.16... Well, let me tell you, Debian is better. A lot.

I think this may help you if you're doubting that working on Debian is sane: Remember that we work together to create the best possible, universal operating system. And even if we're not there yet (and there's a lot of work left), we have succeeded in creating an useable, useful operating system, which is easy to administrate and allows you to have a lot of fun with it. And we did that together, in the occasional moments when fighting with each other wasn't that important.

I have to admit that I haven't invested a lot of time to work on Debian in the last few weeks, but this was due to personal and work reasons. In two weeks, I'll have to return to my usual university schedule, so I'll spend a lot of time on Debian ignoring the exercises I'm supposed to work on.

Also, I have been working on a new server I've rented together with Andreas Barth, playing around with Xen and starting to bootstrap the actual systems we will need. This will mean that I'll have to move my mail and web services in the next few days. I think I'll also move my blog to the new box, but I need to check out how to do this without flooding the planet...

Edd Dumbill: The best of XTech 2006

As I'm finalising the call for participation for XTech 2007 (15-18 May 2007, Paris, France), I've taken a look back at the some of the best received presentations from the 2006 conference. I thought them well worth sharing again here. To be sure of hearing about the call for participation and other XTech 2007 news, sign up for the newsletter or keep an eye on this blog.

Axel Beckert: Mailing lists made my day

Bullshit.  Where did anyone say this?
Why don't you put people in charge who can READ CODE, and SEE THAT
THIS IS ABSOLUTE BULLSHIT.

The OpenSSH 4.4 release announcement says that, actually:
 * Fix an unsafe signal hander reported by Mark Dowd. The signal
   handler was vulnerable to a race condition that could be exploited
   to perform a pre-authentication denial of service. On portable
   OpenSSH, this vulnerability could theoretically lead to
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   pre-authentication remote code execution if GSSAPI authentication
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   is enabled, but the likelihood of successful exploitation appears
   remote.

Well, looks like an exquisite own goal. (Found by Squeeeez.) Then, _rene_ cited a mail from the current Debian Project Leader Anthony Towns on debian-devel in #debian.de, who thought that Switzerland was some foreign word meaning “snowy place” :

I was assuming, of course, that "Switzerland" was some foreign word
meaning "snowy place", but apparently it's actually a country all of
its own, entirely separate to Austria...

And contrary to the usual biases, this geographic unawareness comes from Australia (which is unequal to Austria ;-) and not from the US. :-) Guys, you all made my day. Kind regards from a currently not so snowy snowy place. :-)

Erich Schubert: Fun with explanations

From Top Ten Geek Business Myths:
One of the ironies of the programming world is that using Lisp is vastly more productive than using pretty much any other programming language, but successful businesses based on Lisp are quite rare. The reason for this, I think, is that Lisp allows you to be so productive that a single person can get things done without having to work together with anyone else, and so Lisp programmers never develop the social skills needed to work effectively as a member of a team. A C programmer, by contrast, can't do anything useful except as a member of a team. So although programming in C hobbles you in some ways, it forces you to form groups whose net effectiveness is greater than the sum of their parts, and who collectively can stomp on all the individual Lisp programmers out there, even though one-on-one a Lisper can run rings around a C programmer.
This is probably the first time I've seen somone use Lisp vs. C to explain business mechanics. Fun!

Martin F. Krafft: My hatred for single-language DVDs

Following a friend's recommendation, I set out to buy Kikujiro non natsu this morning, a movie by Takeshi Kitano, one of my favourite contemporary film directors. I came back empty-handed. The movie is available in countless stores (much to my surprise, actually), but all versions I've seen are German-only. I hate synchronised/translated movies. What I want is the original Japanese movie with English subtitles. I do not want some silly German dork utter words and concepts in a way too distant from anything in the Japanese culture. One of the main arguments for DVDs has always been the ability to provide multiple audio and subtitle tracks, so everyone could watch the movie the way they wanted. Publishing a DVD with a single audio track, which isn't even the original, should be punishable. Seriously, what the heck drives people to commit such a blatant act of ignorance? If the answer to this is licence issues then I really don't want to know more; then our world is even more fucked up with respect to intellectual property and art than I was willing to admit until today. Update: Daniel Baumann tells me that audio and video track are licenced separately ("value creation chain" should really be called "cost creation chain"; value is removed, not added, but the alliteration you get for free), so in the interest of maximising profits, the local film distribution just removes half of the film and provides crap instead. I'd wish that they'd save the money on the synchronisation, spend considerably less on subtitle creation, and just publish the films the way their creators made them.
