Raphaël Hertzog: Managing distribution-specific patches with a common source package

In the comments of the article explaining how to generate different dependencies on Debian and Ubuntu with a common source package, I got asked if it was possible to apply a patch only in some distribution. And indeed it is. The source package format 3.0 (quilt) has a neat feature for this. Instead of unconditionally using debian/patches/series to look up patches, dpkg-source first tries to use debian/patches/vendor.series (where vendor is ubuntu, debian, etc.). Note that dpkg-source does not stack patches from multiple series file, it uses a single series file, the first that exists. So what s the best way to use this? Debian should always provide debian/patches/series, they are supposed to provide the default set of patches to use. Any derivative cooperating with Debian can maintain their own series files within the common VCS repository used for package maintenance. They can drop Debian-specific patches (say branding patches for example), and they can add their own on top of the remaining Debian patches. It s worth noting that it s the job of the maintainers to keep both series files in sync when needed. dpkg-source offers no way to have stacked series files (or dependencies between them). If you want to use quilt to edit an alternate series file, you can temporarily set the QUILT_SERIES environment variable to vendor.series . Just make sure to start from a clean state, i.e. no patches applied. Otherwise quilt will be confused by the sudden mismatch between the series file and its internal data (stored in the .pc directory).

Clint Adams: Greedy sellouts

Thank you, Tim.

Jaldhar Vyas: All Hail Aqua Buddha!

My fellow Republicans and I got a nice early Diwali present on Tuesday. ~65 seats in the House ~6 in the senate, ~18 governorships and control of ~20 state legislatures. (Some races haven't been formally called yet.) A few disappointments though. no majority in the Senate and Harry Reid and Barney Frank were not defeated. Still overall its an election to celebrate. Here are a few thoughts. The Election System Is An Embarassment Once again there are several races where the outcome is in doubt because of technical problems with voting. Whatever politics we have, can we agree that it is damn stupid that we still can't get something as simple as counting ballots right? Prediction: The 2012 Republican presidential candidate will come from the Tea Party. While I may be a Republican, I am also a Cosmopolitan East Coast Elitist so the Tea Party didn't move me much. There were a couple of cases (NY and DE atleast) where their candidates were subpar and cost us victory but the best of the new Republicans also came out of this movement. I would rather vote for one of them than Romney, Huckabee, McCain, Gingrich etc. (With the exception of Sarah Palin who is just too polarizing I'm afraid.) The Tea Party itself will subside in a few years as all populist movements do. (Ask the Hope'n'changers.) Young People Are Dumb Part of leftist mythology is the idea that one day "the kids" are going to rise up against the mean old corporate overlords. It ain't going to happen. There was a huge upsurge in first time voters in 2008 but that was because Obama was a novelty act not because they had suddenly discovered the merits of Keynesianism. Now Obama is old and busted so they won't vote anymore. (Not until they have kids and a mortgage sometime in the future.) They'll spend time make cool ironic signs for the Rally to Promote Comedy Central but even the prospect of legalizing pot won't get them to the polling booths in sufficient numbers to defeat the oldies. Why? Because young people are dumb. Prediction: War With Iran If you're President Obama what do you do now? Bipartisanship? Yeah right. Look at what happened to Rep. Cao of Louisiana, the only Republican to vote for Obamacare and one of only two GOP congressmen to lose on Tuesday. Obama actively campaigned for his challenger. Any of the new Republicans who try and compromise with the President will end up under the bus sooner or later as they well know. The President could go full retard with the socialism (progressivism, liberalism whatever. It's all the same.) All his initiatives will be shot down but he can claim to be a martyr to the party of No. (Who will be joined in the Senate by Lieberman and whatever centrist Democrats who are up for reelection in 2012.) But this seems to be the path to a one-term presidency to me. Maybe that's what he wants. He could retire comfortably to the deanship of some Ivy League law school and make a lucrative killing on the rubber chicken circuit. But lets assume he wants to get back in the White House in 2012. One way to get back in touch with the voters is to start getting serious about foreign policy which has either been a joke (Remember the reset button?) a travesty or just copied from the Bush administration. In particular the Obama administration has completely failed in stopping Iran from gaining nuclear technology, sponsoring terrorism in Iraq, Afghanistan and Lebanon, and oppressing its own people. War with Iran would enhance his standing with Conservatives (hey it works for me!) most liberals would go along with it and the extreme Code Pink type loonies can safely be ignored. I say it happens before November 2012.

Andrew Pollock: [life] Zoe at six months

Today, Zoe is six months old. The last three months certainly feel like they've taken their time, but a lot has happened. Developmentally, she's doing great. She's now in the 70th percentile for height (up from around the 25th percentile), and 31st percentile for weight (up from the 25th percentile). She cut her bottom front teeth a few days ago. Crawling is imminent, I'd say. She can already scoot around in reverse, and by a combination of shuffling and rolling, doesn't seem to be having problems moving around the floor. We started her on solids at five months, and she's taken like a duck to water to pureed pumpkin, sweet potato, beans, zucchini, apple, pear, banana and avocado. Speaking of water, she's also decided she likes to drink water from our glasses whenever she sees us doing it. Hilarity usually ensues, closely followed by a change of outfit. She's sleeping well, only waking up once a night under normal circumstances, and that wake-up is getting later and later. She loves her baths. She usually lets out a series of loud sighs as soon as we put her in the bath. She got her first cold a couple of weeks ago. It coincided with her first day in ad hoc daycare, but Sarah and I were both sick as well, so I think it's more likely that she caught the cold from us than from daycare. She's still battling it, but it hasn't really bothered her all that much. She's just a bit snotty. The NoseFrida has been very handy for dealing with this. She had her six month shots today, and seems to be tolerating them fairly well. Sarah says she hardly even cried when she got them. She continues to be a remarkably happy baby. She always wakes up with a smile, she really only fusses if we keep here away for more than a couple of hours, or haven't fed her on time. Even with this current cold she has, she's still stayed very happy. We feel incredibly lucky to have such a wonderful baby. The next big adventure is to try a babysitter. Zoe and me in early October

Gintautas Miliauskas: Living a monastic life for 10 days

About a month ago, at the end of August, I finished a 10-day Vipassana meditation course. This was probably one of the more extreme activities I have ever participated in, and it's well worth a blog post. I found out about the course in a ridiculously trivial way, by following a link in a Reddit comment (I wonder if I could track down that comment...). The website referenced by the comment contained (almost) no new-agey mumbo-jumbo and looked legit in general. I also appreciated the fact that this was a relatively serious and intensive course, which should be enough to form a reasonably founded opinion on meditation in general. When learning sporadically, in small bits, it is hard to say whether the material itself is no good, or you just do not understand it yet and need to study more; I was quite skeptical towards the practice, but wanted to give it fair trial. I was quite impressed that there was a course available in Lithuania, a few hours by train from where I live. Finally, the course was free (by tradition Vipassana is taught without monetary compensation). I went ahead and signed up for a standard introductory 10-day course. Vipassana (also called insight meditation) is a meditation technique allegedly coming back from Gautama Buddha himself (well, all the traditions like to claim that origin...). It has been experiencing a renaissance, partly due to an organization set up by a meditation teacher S. N. Goenka which has founded meditation centers all over the world. The essence of Vipassana is a method of teaching your mind to act instead of merely reacting to outside stimuli such as pain, anger of other people or hardships. The technique provided is to monitor your sensations, watch them with equanimity and suspend any reaction, and slowly it sinks in that all things are temporary and you can choose what to react to and how. That's the basic idea; I don't want to go deep into exposition of Vipassana as there is plenty of information about that (also at the same time the information is almost useless because you have to experience it to really understand it). Instead, I will sure some of the more personal remarks and experiences. The course took place in an cottage near Kretinga, housing around 50 people. The living conditions were absolutely great, and this would have been a true holiday if not for the regime and the rules. The day would start very early, at 4 AM (ending at around 9:30 PM), and we'd do about 12 hours of meditation in total inbetween, with occasional breaks, but the most gruesome part is that no communication at all was allowed with anyone except the manager of the camp (and the teacher during a specified time). That gets to you after a few days, but still, there are people around you, so it's bearable; on the other side, the senses (touch, smell) become very acute. The food was taken care of by volunteers (students who have finished the course), and I could say it was quite good actually. The goal, of course, was to keep the environment from interfering with meditation, and I think it was done very well. The presentation of the actual technique also did not disappoint. Each day a new step would be introduced, with the whole day to practice before moving on. Looking back, the pacing worked well. Every day in the evening there were lectures on theory. They were somewhat informative, but also sometimes annoyingly primitive and verbose. The little mistakes, holes in logic and slight doses of mumbo-jumbo almost drove me nuts by the middle of the course, until I learned not to react to them. Despite the shortcomings of presentation, the simplicity and lucidity of the practice and lightness of theoretical baggage really appealed to me. The whole organisation in general gave the impression of complete transparency, with no strings attached, no financial interests in play and no agitation for further involvement. While there are many meditation techniques, I am happy that I've gone with Vipassana in particular for one reason: Vipassana meditation uses no artificial tools to help you concentrate, such as mantras, visualisations, counting, etc. Such methods make concentration much easier, but they also create a dependence on the methods themselves. I appreciate the purity of Vipassana in this regard. Not everything in the practice is roses though. First, a particular worldview supported by Vipassana is presented as "scientific" and supposedly "the right way to live", and if even if you don't agree, "the truth" of Vipassana will become obvious to you with time. This is a distinctive mark of ideologies. The thing that makes everything break is the reincarnation, which is generally assumed as true, even if it's not shoved down the student's throat. Every rationalization of a world view has a "white lie" (usually related to the concept of eternity somehow) at the core, and in this context reincarnation is it. Given what we know now about the relationship between the mind and the body, reincarnation is absolutely ridiculous and completely untenable, and that breaks all "moral" reasoning for practicing meditation as opposed to doing something else. I'm not the first to bring up this problem, there's plenty of material about it online. The second slippery idea is that the concept of "negative happiness" is central in Vipassana, that is: happiness is defined as lack of suffering. This point is not that unreasonable actually, from personal experience I could indeed call the state of non-suffering happiness, but there is definitely something missing when compared to the state of mind when I'm truly, positively happy. Whether you consider that something important or not, it's definitely there. Third, Vipassana suggests that it is only you who is at fault when your inner state is disturbed; the world affects you as much as you let it, and in order to find happiness you should learn to control the "interface" rather than the outside world, which will usually not behave as you want. This may be correct, but sometimes it could just be easier to fix the world rather than change yourself, and I have the suspicion that it this is much more frequently the case in the modern world compared to the pre-modern environment. (This is one of the points which break when reincarnation is rejected, as with reincarnation you have the whole eternity to fix yourself.) While the complaints are serious, they do not mean complete rejection of Vipassana but rather integration among the various other techniques available. The actual meditation technique is still great for gaining and maintaining mental composure, reducing anxiety and improving well-being. Now, if I could only get used to meditating regularly... If you have the chance, I highly recommend you try out an introductory 10-day course. There is little to lose and a lot to gain. And if you do go ahead, I have two hints. First, do not even think about leaving the course before it's over. Any hardships are temporary and will be overcome quickly. Second, use the time with the teacher, those interactions were very helpful to me. Also, given the "noble silence", talking to someone once in a while will not hurt.

Matt Zimmerman: Weathering the Ubuntu brainstorm

In our first few years, Ubuntu experienced explosive growth, from zero to millions of users. Because Ubuntu is an open project, these people don t just use Ubuntu, but can see what s happening next and influence it through suggestions and contributions. The volume of suggestions quickly became unmanageable through ad hoc discussion, because the volume of feedback overwhelmed the relatively few people who were actively developing Ubuntu.

Ubuntu Brainstorm logo In order to better manage user feedback at this scale, Ubuntu Brainstorm was created in 2008. It s a collaborative filtering engine which allows anyone to contribute an idea, and have it voted on by others. Since then, it s been available to Ubuntu developers and leaders as an information source, which has been used in various ways. The top ideas are printed in the Ubuntu Weekly Newsletter each week. We experimented with producing a report each release cycle and sharing it with the developer community. People have been encouraged to take these suggestions to the Ubuntu Developer Summits. We continue to look for new and better ways to process the feedback provided by the user community. Most recently, I asked my colleagues on the Ubuntu Technical Board in a meeting whether we should take responsibility for responding to the feedback available in Ubuntu Brainstorm. They agreed that this was worth exploring, and I put forward a proposal for how it might work. The proposal was unanimously accepted at a later meeting, and I m working on the first feedback cycle now. In short, the Technical Board will ensure that, every three months, the highest voted topics on Ubuntu Brainstorm receive an official response from the Ubuntu project. The Technical Board won t respond to all of them personally, but will identify subject matter experts within the project, ask them to write a short response, and compile these responses for publication. My hope is that this approach will bring more visibility to common user concerns, help users understand what we re doing with their feedback, and generally improve transparency in Ubuntu. We ve already selected the topics for the first iteration based on the most popular items of the past six months, and are organizing responses now. Please visit brainstorm.ubuntu.com and cast your votes for next time!

Martin Michlmayr: The Boot Process of the SheevaPlug running Debian

I received a number of questions as to how the boot process of the SheevaPlug running Debian works. I've now published an explanation of how u-boot loads the Debian kernel and ramdisk in order to boot Debian.

Sam Hartman: Review of Git DPM

I ve been looking at git dpm. It s a tool for managing Debian packages in git. The description promises the world: use of git to maintain both a set of patches to some upstream software along with the history of those patches both at the same time. It also promises the ability to let me share my development repositories. The overhead is much less than topgit. My feelings are mixed. It does deliver on its promise to allow you to maintain your upstream patches and to use git normallyish. It produces nice quilt patch series. In order to understand the down side, it s necessary to understand a bit about how it works. It maintains your normal branch roughly the way you do things today. There s also a branch that is rebased often that is effectively the quilt series. It starts from the upstream and has a commit for every patch in your quilt series containing exactly the contents of that patch. This branch is merged into your debian branch when you run git dpm update-patches. The down side is that it makes the debian branch kind of fragile. If you commit an upstream change to the Debian branch it will be reverted by the next git dpm update-patches. The history will not be lost, but unless you have turned that change into a commit along your patches branch, git dpm update-patches will remove the change without warning. This can be particularly surprising if the change in question is a merge from the upstream branch. In that case, the merged in changes will all be lost, but since the tip of the upstream branch is in your history, then future merges will not bring them back. If you either also merge your changes into the patches branch, or tell git dpm about a new upstream, then the changes will reappear at the next git dpm update-patches. The other fragility is that rebasing your debian branch can have really unpleasant consequences. The problem is that rebase removes merge commits: it assumes that the only changes introduced by merge commits are resolution of conflicts. However, git dpm synthesizes merge commits. In particular, it takes the debian directory from your debian branch, plus the upstream sources from your upstream branch, plus all the patches you applied and calls that your new debian branch. There s also a metadata file that contains pointers to the upstream branch and the quilt patch series branch. In addition, debian/patches gets populated. Discarding this commit completely would simply roll you back to the previous state of your patches. However, this loses history! There is no reference that is left pointing to the patches branch; the only reason it is still referenced is that it s a parent of the commit rebase is throwing away. This isn t really all that unusual; if you merged in any branch, deleted the branch and rebased away both the merge and the commits from the branch, you d lose history. I do find it a bit easier to do with git dpm. However, it s more likely that you ll manage to rebase and keep the commits from the patches branch. In particular, if the horizon of your rebase includes a merge of the patches branch,then for every patch that involves changes to the debian branch from the point where rebase starts rewriting history, you will see a commit included by your rebase. My suspicion is that this commit is more likely to generate conflicts than usual because it s a patch on top of the upstream sources being applied to a partially patched debian branch. However I have not fully worked through things: it may be that such a patch is exactly as likely to cause conflicts as it would in a git dpm update-patches operation. If that succeeds and you do not manage to fail to pick one of these commits, you ll end up with roughly the same debian sources you started with. There are two key exceptions: the git dpm metadata file is not updated and your debian/patches is not consistent with your sources. The first means you re in the state of the previous paragraph: git dpm update-patches will blow away your changes. The second means that any source package you produce is going to be kind of funky if not out right broken. It is possible to recover from git dpm plus rebase. I think if you git dpm checkout-patches, then cherry pick the patch related commits from your debian branch that were introduced by the rebase, then git dpm update-patches, you ll be in a sane state. Obviously you could also recover by finding the pre-rebase commit and resetting there. I m assuming though that you actually needed to rebase for some reason. Of course git dpm does involve a space penalty. You generate a commit for every patch in your quilt series for every version of the upstream sources you deal with. Also, you will introduce and store every version of the quilt series directly in your debian directory. The extra commits probably aren t a big deal: the blobs probably delta compress well. I m not sure though that the quilt patch blobs will compress well with other things. In my opinion the ability to get nice quilt patches is well worth the space penalty. In conclusion, git dpm is a sharp tool. Actually, I think that s understating things. Git dpm involves a bunch of rotating blades. You stick your face and foot between the blades, and if you use it correctly, there s exactly enough clearance that nothing gets damaged and you get some fairly neat results. Other outcomes are available. I m still trying to evaluate if it is worth it. I think the tradeoff might be different for something like the krb5 package which is maintained by two very experienced maintainers than say for Shibboleth which seems to involve several more maintainers. I m not sure that there is much git dpm can do to make things better. Even detecting loss-of-foot events might be kind of tricky.

John Goerzen: Some Amateur Radio Statistics

I ve had a lot of fun with amateur radio since I got licensed in July! Here are some numbers regarding my HF contacts. Not included in this are probably hundreds of more contacts on VHF or UHF, which are more local bands and not typically logged. One of my favorite moments happened recently when I turned on my digital program (fldigi) and happened to tune to 17m. I don t have antennas there and don t usually bother, since there s rarely something I can receive. But I saw two PSK-31 (digital) signals. One of them was a Japenese station calling CQ. I replied, and although we had some noise (perhaps due to my lack of a 17m antenna), made my first contact with Japan! Things like this are part of the fun of amateur radio. Sometimes things that have no business working actually do, and I get a surprise like this.

Tim Retout: Boxes

Today I bought two Ikea boxes. Possibly the best 8 I have ever spent - I still have a load of bits of paper to sort out, but now they're all hidden from sight in a sleek, black and chrome rivet-effect container. More than simply reclaiming my sofa from the piles of notes, they seem to point to a higher truth; they fit their purpose in a way that is hard to articulate, like some platonic Form. Taking complexity, and making it manageable; but more than that, elegant. At some point, I lost the ability to explain to my friends and family what it is I spend my spare time doing. I feel isolated; I cannot express what motivates me, or even what it is I do. In fact, sometimes I can't even describe it to myself. Perhaps I never could. I don't believe that you can buy happiness; but if I surround myself with metaphors, maybe I can buy clarity.

Adnan Hodzic: I want Xperia X10 Android 2.1 update now!

Story I bought Xperia X10i this summer during DebConf10 in NYC, I loved this phone from very beginning however what bothered me was that it was still stuck on outdated Android 1.6. To get your own custom Android on it, wasn t quite possible because no one managed to hack bootloader even though some of the guys at XDA where getting pretty close. Long story made short, Sony Ericsson has finally release their Android 2.1 update, but made it available only for Nordic region, they explained it all on their blog where they also sent a message for paranoid users as they called them. I thought, if I gave it all this time I can wait a little bit longer, but then one of my friends (@sahinovic) gave me a good pointer to go in right direction with using custom ROM, Nordic for example? So this is where I got my idea. I want 2.1 update now! Please note steps below will get you Android 2.1 update, but AFAIK you ll also lose your warranty 1. Root your phone If you don t have your phone rooted, this can now be done in single click. Get X10 Root and follow instructions on screen. 2. Edit system/default.prop Get Root Explorer, mount r/w (upper right corner), edit system/default.prop Lines you re concentrating on are 1 and 3 Let s say they are:
ro.semc.version.cust=1237-0333
ro.product.name=X10_1237-0333
Edit them to look like:
ro.semc.version.cust=1234-8465
ro.product.name=X10_1234-8465
Save the file and it s gonna create automatic backup of original file. 3. Get the updates using SEUS Turn off your phone, launch SEUS, plugin in the USB cable while holding back button, SEUS is going to tell you have updates for your phone Smile Follow on screen instructions. Enjoy the update Smile Conclusion X10 is a pretty sweet phone, but with it being so closed, it also closes a lot of doors to hacking it and playing with it, great example would be this update itself, since right now Android 2.1 update is an outdated one. However 2.1 update brings new life into it, just as it s a brand new phone, it s more responsive and much much faster. And do take a backup before this update, because I lost everything from my contacts to internet settings, but all files on my sd card remained intact. If you want to discuss anything regarding this topic please do so in comment area below or find me on Twitter.

Raphaël Hertzog: 5 free software to support with Flattr

Flattr FOSS LogoIt s already the fourth issue of Flattr FOSS: it means 20 different projects using Flattr that I presented you. Here are the 5 suggestions for November:
  1. Redshift is a small utility that adjusts the color temperature of your screen to make it less aggressive on your eyes, in particular during evening/nights. It uses the time of the day and the geographic location to know whether it s night or day. I discovered it this summer and I liked it, although I m not running it permanently.
  2. Noscript is a Firefox plugin to control what sites can execute javascript, flash and other plugins. All those are creating supplementary security risks and you browse safer if you allow only some sites to run them. This is the number one entry on Flattr in the opensource category, it recently took the place of dpkg.
  3. phyMyAdmin is a web interface to manage MySQL databases. If you have such a database on a web-hosting service, you have likely already seen it in action. It s an award-winning software with a 12 year history, it s not so common for PHP applications. :-)
  4. Chromium maintenance in Debian. Chromium is a rapidly-evolving & complex software and Giuseppe Iuculano has been tirelessly working on packaging it. Almost alone within Debian. He deserves kudos for his work even though he reused work made by Fabien Tassin on the Ubuntu package.
  5. Dulwich is a pure-Python implementation of the Git file formats and protocols. It s an important building block for interoperability between Bazaar and Git: bzr-git (a Bazaar plugin providing Git integration) is notably using it. Given the large usage of bzr in Ubuntu and the popularity of Git world-wide, it s important to have such gateways.
This article is part of the Flattr FOSS project.
Update: mentioned the work of Fabien Tassin on the chromium package within Ubuntu.

Russell Coker: Communication Shutdown and Autism

The AEIOU Foundation The AEIOU Foundation [1] is a support and advocacy organisation for people on the Autism Spectrum, note that they clearly say Autism Spectrum Disorder (ASD) on their About page, some of what they write would be less wrong if it was claimed to apply to only non-verbal Autistics or people claimed to be Low Functioning Autistic (LFA). But in regard to the Autism Spectrum they just don t seem to know much about it, a lot of their web pages seem to be based on the assumption that anyone who is on the Spectrum will be lucky if they can ever live independently. However it seems that most people who can be diagnosed with an ASD have typical social skills by the standards of the IT industry and can get by without any special assistance. The entire site seems to be written about people on the Spectrum by people who know little of their experiences and contains hardly any information that matches what I ve read from various people on the Spectrum (of course there are a wide range of experiences that differ greatly). They have a link to Autism Related Sites which starts with Autism Speaks (the Wikipedia page about Autism Speaks is worth reading note the section about immunisation research which has been repeatedly debunked and the section about legal action against a young autistic blogger). There are many good reasons why Autism Speaks is so widely hated among people on the Spectrum. I think that recommending Autism Speaks is a sign of willful ignorance of almost everything related to Autism. In their page about describing Autism to NTs they say Imagine if you suddenly woke up in a foreign country, did not speak the language and had no way of effectively communicating with the people around you . I ve been diagnosed with Asperger Syndrome by a psychologist who considers that to be the same as High Functioning Autism (HFA) and I ve visited more than a few countries. I find the comparison of the Autistic experience to visiting another country to be so strange that I don t even know where I would begin if I was to comment on where it went wrong. Finally they have a scrolling bar listing their advertisers at the bottom of ever single page on their site. If someone was going to design a web site specifically to annoy people on the Spectrum then such a scrolling banner would be a good place to start. Now they probably do some good things to help families with children on the Spectrum. But their ability to do good is really hindered by the lack of input from people on the spectrum, Rachel Cohen-Rottenberg (leader of the Vermont Chapter of the Autistic Self Advocacy Network) wrote an interesting post about AEIOU and noted that none of the people who run AEIOU are Autistic [2]. The Communication Shutdown Someone got the idea that Neuro-Typical people (NTs) should try and understand what it s like to be on the Spectrum which is a reasonable idea. But they decided that the way to do so is to have them refrain from Internet based socialisation and not use Facebook and Twitter for one day. It seems to me that most people on the Spectrum primarily socialise via the Internet, so ceasing Internet based socialisation is likely to make their experience less like that of people on the Spectrum. I m getting a mental image of a bunch of NTs deciding to go to a night-club for their Internet free evening and then imagining that they are somehow empathising with the experience of people who can never enjoy a night-club. As an aside, a web site which has anything at all related to disabilities shouldn t rely on Flash the Communication Shutdown site totally fails in this regard. No Stereotypes Here has an interesting analysis of this situation, among other things they comment on the irony of having someone ask them to stop using twitter as part of this campaign [3]. One thing that they suggest is for NTs to have a day without any communication at all. Some Suggestions for People who Want to Understand As a communication exercise, try going shopping without speaking, just use hand gestures. For bonus points try doing so in a foreign country where you don t know the language so you need bidirectional non-verbal communication with some luck you can complete a transaction without the shopkeeper realising that you are a foreigner. This won t actually give you much of the Autistic experience, but it s a good exercise in understanding how communication works. Someone who wanted to know the down-side of being on the Spectrum could find a sports bar where most patrons support one team and then enter the bar while wearing a jersey indicating support for an opposing team. I don t recommend doing this because it really wouldn t be fun, but for a quick approximation of the experience it would probably work well. It seems to me that paying $5 to a charity and then boasting about doing so on your Facebook page for a day is an easy thing to do. A harder task would be to spend a day reading about the experiences of the people in question and then giving $5 to a charity that is well regarded by the target group. Another possible way of gaining some understanding would be to have a party where everyone brings their laptop and uses only electronic communication no speaking at all. This is in fact fairly close to what some of the Geekier (possibly Autistic) members of the IT community do.

Stefano Zacchiroli: mini debconf paris - success

I'm just back home after Paris mini-DebConf. I'm happy, excited, and exhausted almost as if it had been a full fledged DebConf. That's enough in my book to consider the event a complete success. As far as I know, it has been the first mini-DebConf held in Paris and about 150 people have come to attend the event from all over Europe. Off the top of my head I've met friends from at least: Spain, UK, France (obviously!), Italy, Germany, Austria, Switzerland, Greece. I'm still very much impressed by such a diverse attendance. Initially, I had planned the first "DPL strike" ever (i.e. not doing anything DPL-related) for the duration of the conference, in order to take part into the BSP. That agenda has been pretty much subverted by a last minute emergency, by chatting with loads of people, and by actually finalizing the Debian Sprint Program, which had been at the top of my Debian TODO list for quite a while now. Nonetheless, I've managed to advance a bit on a couple of RC bugs, which belong to the "annoying/pointless/but-still-valid" category. They are not solved yet, but I hope to have good news to share soon. Bottom line: I loved the event. and I've even managed to avoid getting killed by my (local) family for taking part in a Debian-weekend after an almost full week of Debian traveling, which is another success on its own right :-) Closing advice: beside some last minute legwork, I did essentially nothing to organize this mini-DebConf, your kudos should be better directed to Carl Chenet and Mehdi Dogguy for the organization. Other gifts such as bug fixes can be directed to the speakers, sponsors, and loads of other helpers from Debian France and not in particular Xavier Oswald, Valessio Brito, Tanguy Ortolo, Nattie Mayer-Hutchings, Luca Capello, Stephane Glondu, and others which surely I'm forgetting to mention here (sorry about that). Kudos folks ... let's do it again next year! (SCNR)

Jan Wagner: linux-image-2.6.32-bpo.5-xen-686 and xen/xen-common from squeeze broken?

I m experiencing since some time (out of the blue) spontaneous reboots of some of my dom0s on lenny/i386 (others don t have this effect). As result of this, I started rolling out linux-image-2.6.32-bpo.5-xen-686 from bpo and backported xen and xen-common from testing:

# dpkg -l grep xen grep bpo
ii libxenstore3.0 4.0.1-1~bpo50+1 Xenstore communications library for Xen
ii linux-image-2.6.32-bpo.5-xen-686 2.6.32-26~bpo50+1 Linux 2.6.32 for modern PCs, Xen dom0 suppor
ii xen-hypervisor-4.0-i386 4.0.1-1~bpo50+1 The Xen Hypervisor on i386
ii xen-linux-system-2.6.32-bpo.5-xen-686 2.6.32-26~bpo50+1 Xen system with Linux 2.6.32 on modern PCs (
ii xen-tools 4.1-1~bpo50+1 Tools to manage Debian XEN virtual servers
ii xen-utils-4.0 4.0.1-1~bpo50+1 XEN administrative tools
ii xen-utils-common 4.0.0-1~bpo50+1 XEN administrative tools common files
ii xenstore-utils 4.0.1-1~bpo50+1 Xenstore utilities for Xen This fixed the problem of spontaneous reboots for all of the systems I have migrated . until now! Last week I tried this solution on my private system and it failed in some way.
boot problems
A full dump of the syslog is also available. It looks like /etc/rcS.d/S03udev is hanging in some way .. the syslog for this looks like:

Oct 29 20:51:07 mordor kernel: [ 17.728120] Code: 04 00 00 00 00 83 3c 24 10 74 32 77 0c 83 3c 24 08 0f 85 9f 00 00 00 eb 12 83 3c 24 20 74 30 83 3c 24 40 0f 85 8d 00 00 00 eb 35 <0f> b6 01 8b 54 24 20 89 02 c7 42 04 00 00 00 00 eb 79 0f b7 01

Priority:-1 extents:1 across:10000452k The dom0 is there hanging in some way I don t have an exact way to get the system proceed from there usually I need to wait some seconds and pressing ^C after a while will get the box up.
Anyways I remember there are some problems with udev >= 150 and older kernels, which is also documented in the squeeze release notes. Maybe there is also a problem with older udev and newer kernels? But why is this combination working on other systems? Booting linux-image-2.6.32-bpo.5-686 works without any issue anyways, so it seems xen related. Any idea is appreciated!
UPDATE: I ve also reported this via #602109.

Christian Perrier: Debian Installer beta1 released

Otavio Salvador announced the release of the beta1 version of Debian Installer, the installation system for Debian. This release is made in preparation of the overall release of Debian Squeeze. It should be followed soon by another release ("Release Candidate", probably) with a full localization update (that involves building/uploading all packages to get localization changes in). That release is dedicated to Frans Pop, who worked for two years as Debian Installer release manager and continued to bring very significant contributions to D-I later on.

Rapha&#235;l Hertzog: Latest features of dpkg-dev: debian packaging tools

I m attending the mini-Debconf Paris and I just gave a talk about the latest improvement of dpkg-dev the package providing the basic tools used to build Debian packages. Latest is a bit stretched since it embraces the last 2-3 years of development. My talk covered the following topics: The slides are relatively verbose so that you can understand them even if you did not attend the talk. Click here to get the slides. Related links This section points to various articles that cover more extensively some of the features mentioned in my talk.

Alexander Reichle-Schmehl: Release Critical Bug report for Week 43

The bug webinterface of the Universal Debian Database currently knows about the following release critical bugs:
In Total:695
Affecting Squeeze:284
Squeeze only:71
Remaining to be fixed in Squeeze:213
Of these 213 bugs, the following tags are set:
Pending in Squeeze:7
Patched in Squeeze:40
Duplicates in Squeeze:24
Can be fixed in a security Update:14
Contrib or non-free in Squeeze:7
Otherwise fixed in Squeeze:32
Ignoring all the above (multiple tags possible), 126 bugs need to be fixed by Debian Contributors to get Debian 6.0 Squeeze released. However, with the view of the Release Managers, 169 need to be dealt with for the release to happen. Please see Interpreting the release critical bug statistics for an explanation of the different numbers.

Obey Arthur Liu: Debian & the Google Code-in 2010, requesting tasks

Debian so far had a nice experience with the Google Summer of Code and this year, Google is going to run the Google Code-in. We have applied and would now need some help from you all.
In the words of the official announcement: Google Code-in, Google s contest to introduce pre-university students to the many kinds of contributions that make open source software
development possible, is starting on November 22, 2010. Google is inviting students worldwide to produce a variety of open source code,
documentation, training materials and user experience research for the organizations participating this year. These tasks include: I have applied on behalf of Debian and we now need a series of short tasks (1-2 weeks work) to propose in all these areas.
The selected mentoring organizations will be announced on November 5th 2010.
As you can see, this is an interesting project as the individual tasks are closer in size to an RC bug and encompass a wider range of areas than the Summer of Code. I set up a welcome page and a tasks page.
Please fill in your tasks ideas ASAP. You can also volunteer to help as admin and/or mentor.
We will be using the usual communication channels used for the Summer of Code:
