Terah went to college at Purdue University, and always enjoyed basketball games there. I ve not been much of a sports fan, but have enjoyed watching Purdue games with her on TV. Terah has been wanting to see a game in person for awhile, so a couple of weeks ago, we went. It was a really fun weekend! When we planed the trip, we had no idea that the Purdue-Ohio State game was going to be such a big one. We walked over from the Union Club Hotel where we were staying on the Purdue campus. People were streaming towards Mackey Arena from all directions. Once inside, it was already loud and buzzing people cheering, the band playing. I ve never experienced anything quite so loud. The game started out badly for Purdue; they were down a few points up front. The entire game was a close one, and the crowd sometimes got so loud that nothing else could be heard not even the band or the announcer. When it became clear at the end that Purdue won the game, the people behind me and apparently 12,000 others began screaming at the top of their lungs. My hearing did eventually return to normal. So did my throat, which had gotten rather sore from from cheering myself. This was our first road trip since I got my amateur radio license. I had a lot of fun visiting with people as we drove. I talked to a retired railroad engineer that used to take an amateur radio with him in his locomotive. As he went through a certain town where he had friends he liked to talk with on the radio, he d get their attention by blowing CQ in Morse code with the train s whistle. Some people in Kansas City had us laughing as we passed through. In Missouri, I talked with some farmers and a World War II vet. In Champaign, IL, I visited with a retired Unix systems administrator that had spent decades working with Unix operating systems. Our hotel was connected to the Purdue Memorial Union, a large and historic building. Besides having some ice cream at the Sweet Shop one evening, we also spent a bit of time exploring it. I noticed that the Purdue Amateur Radio Club was having a testing session in there. We walked past once it was underway, and one of the students was not very busy. I introduced myself and asked if we could see their shack. It was neat to see all the equipment some of it quite old in the room that they must have been using for decades. Terah, of course, had ideas for visiting a number of her favorite places while we were there. We visited Arni s and Bruno s, both pizza places. Bruno s happens to be a Swiss pizza place, so much to my surprise, I had Wienerschnitzel there, which was excellent. We ate a (week late) Valentine s dinner at Bistro 501. On our way back, we also chatted with various people on the radio, though not quite as much. We got helpful suggestions for which route to take, and stopped at the excellent Bobby D s Merchant St. BBQ in Emporia, KS for supper. The boys had also enjoyed their weekend with grandparents, but were glad to see us back. They were particularly interested to see a lot of train videos from Youtube with me the next day.

The nominations for Debian Project Leader elections for 2011 are open. As always, I'm tempted to nominate myself, but after thinking about it, I again conclude that I shouldn't. If I did nominate myself, there's a couple of things I'd like to push for.

• re-think the new maintainer process: if you are known among existing members of the project to do good work for the project, and to be trustworthy, then you should be offered membership, and that means voting rights (upload and login rights are less important)
• in general, attract more new contributors to the project
• more rotation for key positions: it is good for the project if positions like DAM, DSA, secretary, etc, get new people into these positions, so that the knowledge and skills get spread out more
• improve how we deal with conflict, especially internally: we've reduced general flame levels a lot over the past fix years or so, but we still have problems dealing with conflict or disagreements
  • this should probably include a more explicit consensus on what is acceptable and what is unacceptable behavior within the project (lists, irc, bts, etc), and how this should be enforced
  • this could also include education and training of how to deal with conflict; perhaps even about dealing with cross-cultural issues
  • could also include neutral "ambassadors", "diplomats", or "hostage negotiators" that step into a heating situation and attempt to defuse it before it blows up
• regular online training sessions, e.g., for packaging in general, packaging of particular kinds of applications, etc
  • Debian Women has run a number of such sessions over IRC, and Ubuntu runs such sessions regularly
  • both popular and useful
  • realtime access to a teacher is qualitatively different from reading books or web pages

The DPL position is inherently a political one, which is why nothing in the list above is technical. On the other hand, I want to concentrate my Debian time on doing stuff that is fun, and right now that means writing code. I want to write code for Debian.

One of features for Gammu SMSD which was for quite a long time in my head was ODBC support. With unified SQL backend we have right now it should be pretty easy to add support for it so I gave it a try. It really did not take to long and the ODBC driver is committed to git and will be part of next release. The great benefit of this is that we get native database support on Windows without need to linking against database libraries, which is always painful. The ODBC driver behaves like any other SQL based driver for SMSD, so if you are familiar with it, the configuration won't surprise you:

[smsd]
service = sql
driver = odbc
host = dsn_of_your_database
user = username
password = password

All important information about the driver should be available in the manual.

Christian is a figure of Debian, not only because of the tremendous coordination work that he does within the translation project, but also because he s very involved at the social level. He s probably in the top 5 of the persons who attended most often the Debian conference. Christian is a friend (thanks for hosting me so many times when I come to Paris for Debian related events) and I m glad that he accepted to be interviewed. He likes to speak and that shows in the length of his answers but you ll be traveling the world while reading him. My questions are in bold, the rest is by Christian. Who are you? I am a French citizen (which is easy to guess unless you correct my usual mistakes in what follows). I m immensely proud of being married for nearly 26 years with Elizabeth (who deserves a statue from Debian for being so patient with my passion and my dedication to the project). I m also the proud father of 3 wonderful kids , aged 19 to 23. I work as team manager in the Networks and Computers Division of Onera the French Aerospace lab , a public research institute about Aeronautics, Space and Defense. My team provides computer management services for research divisions of Onera, with a specific focus put on individual computing. I entered the world of free software as one of the very first users of Linux in France. Back in the early 1990 s, I happened (though the BBS users communities) to be a friend of several early adopters of Linux and/or BSD386/FreeBSD/NetBSD in France. More specifically, I discovered Linux thanks with my friend Ren Cougnenc (all my free software talks are dedicated to Ren , who passed away in 1996). You re not a programmer, not even a packager. How did you come to Debian? I m definitely not a programmer and I never studied computing (I graduated in Materials Science and worked in that area for a few years after my PhD). However, my daily work always involved computing (I redesigned the creep testing laboratory and its acquisition system all by myself during my thesis research work). An my hobbies often involved playing with home computers, always trying to learn about something new. So, first learning about a new operating system then trying to figure out how to become involved in its development was quite a logical choice. Debian is my distro of choice since it exists. I used Slackware on work machines for a while, but my home server, kheops, first ran Debian 1.1 when I stopped running a BBS on an MS-DOS machine to host a news server. That was back in October 1996. I then happened to be a user, and more specifically a user of genealogy software, also participating very actively in Usenet from this home computer and server, that was running this Debian thing. So, progressively, I joined mailing lists and, being a passionate person, I tried to figure out how I could bring my own little contribution to all this. This is why I became a packager (yes, I am one!) by taking over the geneweb package, which I was using to publish my genealogy research. I applied as DD in January 2001, then got my account in July 2001. My first upload to the Debian archive occurred on August 22nd 2001: that was of course geneweb, which I still maintain. Quite quickly, I became involved in the work on French localization. I have always been a strong supporter of localized software (I even translated a few BBS software back in the early 90 s) as one of the way to bring the power and richness of free software to more users. Localization work lead me to work on the early version of Debian Installer, during those 2003-2005 years where the development of D-I was an incredibly motivating and challenging task, lead by Joey Hess and his inspiring ideas. From user to contributor to leader, I suddenly discovered, around 2004, that I became the coordinator of D-I i18n (internationalization) without even noticing You re the main translation coordinator in Debian. What plans and goals have you set for Debian Wheezy? As always: paint the world in red. Indeed, this is my goal for years. I would like our favorite distro to be able to be used by anyone in the world, whether she speaks English, Northern Sami, Wolof, Uyghur or Secwepemcts n. As a matter of symbol, I use the installer for this. My stance is that one should be able to even install Debian in one s own language. So, for about 7 years, I use D-I as a way to attract new localization contributors. This progress is represented on this page where the world is gradually painted in red as long as the installer supports more languages release after release. The map above tries to illustrate this by painting in red countries when the most spoken language in the country is supported in Debian Installer. However, that map does not give enough reward to many great efforts made to support very different kind of languages. Not only various national languages, but also very different ones: all regional languages of Spain, many of the most spoken languages in India, minority languages such as Uyghur for which an effort is starting, Northern Sami because it is taught in a few schools in Norway, etc., etc. Still, the map gives a good idea of what I would like to see better supported: languages from Africa, several languages in Central Asia. And, as a very very personal goal, I m eagerly waiting for support of Tibetan in Debian Installer, the same way we support its sister language, Dzongkha from Bhutan. For this to happen, we have to make contribution to localization as easy as possible. The very distributed nature of Debian development makes this a challenge, as material to translate (D-I components, debconf screens, native packages, packages descriptions, website, documentation) is very widely spread. A goal, for years, is to set a centralized place where translators could work easily without even knowing about SVN/GIT/BZR or having to report bugs to send their work. The point, however, would be to have this without making compromises on translation quality. So, with peer review, use of thesaurus and translation memory and all such techniques. Tools for this exist: we, for instance, worked with the developers of Pootle to help making it able to cope with the huge amount of material in Debian (think about packages descriptions translations). However, as of now, the glue between such tools and the raw material (that often lies in packages) didn t come. So, currently, translation work in Debian requires a great knowledge of how things are organized, where is the material, how it can be possible to make contribution reach packages, etc. And, as I m technically unable to fulfill the goal of building the infrastructure, I m fulfilling that role of spreading out the knowledge. This is how I can define my coordinator role. Ubuntu uses a web-based tool to make it easy to contribute translations directly in Launchpad. At some point you asked Canonical to make it free software. Launchpad has been freed in the mean time. Have you (re)considered using it? Why not? After all, it more or less fills in the needs I just described. I still don t really figure out how we could have all Debian material gathered in Rosetta/Launchpad .and also how Debian packagers could easily get localized material back from the framework without changing their development processes. I have always tried to stay neutral wrt Ubuntu. As many people now in Debian, I feel like we have reached a good way to achieve our mutual development. When it comes at localization work, the early days where the everything in Rosetta and translates who wants stanza did a lot of harm to several upstream localization projects is, I think, way over. Many people who currently contribute to D-I localization were indeed sent to me by Ubuntu contributors .and by localizing D-I, apt, debconf, package descriptions, etc., they re doing translation work for Ubuntu as well as for Debian. Let s say I m a Debian user and I want to help translate Debian in my language. I can spend 1 hour per week on this activity. What should I do to start? Several language teams use Debian mailing lists to coordinate their work. If you re lucky enough to be a speaker of one of these languages, try joining debian-l10n-<yourlanguage> and follow what s happening there. Don t try to immediately jump in some translation work. First, participate to peer reviews: comment on others translations. Learn about the team s processes, jargon and habits. Then, progressively, start working on a few translations: you may want to start with translations of debconf templates: they are short, often easy to do. That s perfect if you have few time. If no language team exists for your language, try joining debian-i18n and ask about existing effort for your language. I may be able to point you to individuals working on Debian translations (very often along with other free software translation efforts). If I am not, then you have just been named coordinator for your language I may even ask you if you want to work on translating the Debian Installer. What s the biggest problem of Debian? We have no problems, we only have solutions We are maybe facing a growth problem for a few years. Despite the increased welcoming aspects of our processes (Debian Maintainers), Debian is having hard times in growing. The overall number of active contributors is probably stagnating for quite a while. I m still amazed, however, to see how we can cope with that and still be able to release over the years. So, after all, this is maybe not a problem Many people would point communication problems here. I don t. I think that communication inside the Debian project is working fairly well now. Our famous flame wars do of course still happen from time to time, but what large free software project doesn t have flame wars? In many areas, we indeed improved communication very significantly. I want to take as an example the way the release of squeeze has been managed. I think that the release team did, even more this time, a very significant and visible effort to communicate with the entire project. And the release of squeeze has been a great success in that matter. So, there s nearly nothing that frustrates me in Debian. Even when a random developer breaks my beloved 100% completeness of French translations, I m not frustrated for more than 2 minutes. You re known in the Debian community as the organizer of the Cheese & Wine Party during DebConf. Can you tell us what this is about? This is an interesting story about how things build themselves in Debian. It all started in July 2005, before DebConf 5 in Helsinki. Denis Barbier, Nicolas Fran ois and myself agreed to bring at Debconf a few pieces of French cheese as well as 1 or 2 bottles of French wine and share them with some friends. Thus, we settled an informal meeting in the French room where we invited some fellows: from memory, Benjamin Mako Hill, Hannah Wallach, Matt Zimmermann and Moray Allan. All of us fond of smelly cheese, great wine plus some extra p t home-made by Denis in Toulouse. It finally happened that, by word of mouth, a few dozens of other people slowly joined in that French room and turned the whole thing into an improvized party that more or less lasted for the entire night. The tradition was later firmly settled in 2006, first in Debconf 6 in Mexico where I challenged the French DDs to bring as many great cheese as possible, then during the Debian i18n meeting in Extremadura (Sept 2006) where we reached the highest amount of cheese per participant ever. I think that the Creofonte building in Casar de C ceres hasn t fully recovered from it and is still smelling cheese 5 years after. This party later became a real tradition for DebConf, growing over and over each year. I see it as a wonderful way to illustrate the diversity we have in Debian, as well as the mutual enrichment we always felt during DebConfs. My only regret about it is that it became so big over the years that organizing it is always a challenge and I more and more feel pressure to make it successful. However, over the years, I always found incredible help by DebConf participants (including my own son, last year a moment of sharing which we will both remember for years, i think). And, really, in 2010, standing up on a chair, shouting (because the microphone wasn t working) to thank everybody, was the most emotional moment I had at Debconf 10. Is there someone in Debian that you admire for their contributions? So many people. So, just like it happens in many awards ceremonies, I will be very verbose to thank people, sorry in advance for this. The name that comes first is Joey Hess. Joey is someone who has a unique way to perceive what improvements are good for Debian and a very precise and meticulous way to design these improvements. Think about debconf. It is designed for so long now and still reaching its very specific goal. So well designed that it is the entire basis for Joey s other achievement: designing D-I. Moreover, I not only admire Joey for his technical work, but also for his interaction with others. He is not he loudest person around, he doesn t have to .just giving his point in discussion and, guess what? Most of the time, he s right. Someone I would like to name here, also, is Colin Watson. Colin is also someone I worked with for years (the D-I effect, again ) and, here again, the very clever way he works on technical improvements as well as his very friendly way to interact with others just make it. And, how about you, Rapha l? I m really admirative of the way you work on promoting technical work on Debian. Your natural ability to explain things (as good in English as it is in French) and your motivation to share your knowledge are a great benefit for the project. Not to mention the technical achievements you made with Guillem on dpkg of course! Another person I d like to name here is Steve Langasek. We both maintain samba packages for years and collaboration with him has always been a pleasure. Just like Colin, Steve is IMHO a model to follow when it comes at people who work for Canonical while continuing their involvment in Debian. And, indeed, Steve is so patient with my mistakes and stupid questions in samba packaging that he deserves a statue. We re now reaching the end of the year where Stefano Zacchiroli was the Debian Project Leader. And, no offense intended to people who were DPL before him (all of them being people I consider to be friends of mine), I think he did the best term ever. Zack is wonderful in sharing his enthusiasm about Debian and has a unique way to do it. Up to the very end of his term, he has always been working on various aspects of the project and my only hope is that he ll run again (however, I would very well understand that he wants to go back to his hacking activities!). Hat off, Zack!I again have several other people to name in this Bubulle hall of Fame : Don Armstrong, for his constant work on improving Debian BTS, Margarita Manterola as one of the best successes of Debian Women (and the most geeky honeymoon ever), Denis Barbier and Nicolas Fran ois because i18n need really skilled people, Cyril Brulebois and Julien Cristau who kept X.org packaging alive in lenny and squeeze, Otavio Salvador who never gave up on D-I even when we were so few to care about it. I would like to make a special mention for Frans Pop. His loss in 2010 has been a shock for many of us, and particularly me. Frans and I had a similar history in Debian, both mostly working on so-called non technical duties. Frans has been the best release manager for D-I (no offense intended, at all, to Joey or Otavio .I know that both of them share this feeling with me). His very high involvment in his work and the very meticulous way he was doing it lead to great achievements in the installer. The Installation Guide work was also a model and indeed a great example of non technical work that requires as many skills as more classical technical work. So, and even though he was sometimes so picky and, I have to admit, annoying, that explains why I m still feeling sad and, in some way, guilty about Frans loss. One of my goals for wheezy is indeed to complete some things Frans left unachieved. I just found one in bug #564441: I will make this work reach the archive, benefit our users and I know that Frans would have liked that.

I was going to make this a comment against Ritesh Raj Sarraf's post about patents and pharmaceuticals but the comment got way too long.

The basic problem is that patents on pharmaceuticals cannot be directly compared to patents on software and the explanation gets a bit involved. It's worse than apples and oranges, it's more like comparing an algorithm to a piece of DNA.

Patented pharmaceuticals must declare the precise chemical formula of the molecule (and a whole lot else besides) before the molecule can be brought to market but the company holding the patent is legally prevented from protecting themselves against slightly different molecules which are blatantly based on the protected molecule. All modification results in a new patentable product, legally separated from the original.

Therefore, the first company to patent a molecule from a new class is instantly joined in the field by other companies who are (obviously) watching the research news channels very carefully. (In their shoes, you would do the same or you go bust.) These companies simply add a flourine ion or change a hydrogen to a hydroxl group or any other number of minor, apparently inconsequential, changes. Changes which, in software, would be deemed a derivative work and would be roughly equivalent to changing a single local variable from a 16bit integer to a 32bit integer in a single function in a single file in the entire codebase. i.e. a trivial bug fix or even a typo.

A molecule with a couple of hundred atoms can have a change affecting one atom and be a completely new patentable item without any risk of the other company being sued for patent infringement, plagiarism, copyright violation (there is no copyright) or any other barrier. It's common to find that molecule foo is joined on the market by a desoxyfoo and a flourofoo etc. with a chlorofoo just around the corner, within months of the class-leader being launched. It can't be compared to software - effectively, every new release gets a new patent which covers the entirety of everything contained in that release, even if 99.999999999% of it is precisely the same as is covered under other several other patents held by extremely litigious competitors.

Modification is simply not prohibited - copying without making any changes whatsoever to the active molecule is prohibited. Changes to the inactive ingredients will be prosecuted - changes to the active ingredient will not. Comparing this with software is likely to drive you insane.

For example, the mere process of packaging an upstream release for a distribution would be patent infringement in pharmaceutical terms - UNLESS you deliberately patch the original source to make an utterly trivial and apparently pointless change. At that point, the upstream completely disown your entire release and you would have to fix every bug yourself - without the original upstream even telling you whether they fixed the same bug themselves, because they aren't ABLE to modify the upstream code without starting a whole new project and they won't tell you why or how they changed things. There is no such thing as an alpha-release of a molecule. Every release is final and no subsequent modification is possible - unless it only affects the inactive ingredients, e.g. by adding a slow release coating. These changes can affect the way that the molecule acts on the test subject / patient but must not change the active ingredient itself in any identifiable way. So the upstream can make a new wrapper (new packaging) but nobody else is allowed to do so until the patent expires. Once the patent expires, every one and their dog is allowed to make identical copies of the active ingredient in their own inactive packaging and these are called generics. Generics still need testing to ensure that the active ingredient truly is the same and that the generic behaves in the same way as the original but this process is cheaper than making a change to the active molecule.

A changed active molecule is an entirely new substance, it gets a new patent and it needs to go through largely the same amount of testing as the patented original but the new company still gets a head start on what the molecule is likely to do and what side-effects (by now noticeable with the class-leader product which is in large scale trials or even on the market) would be harmful to the future usefulness of their new, derivative, molecule. The new company simply jumps onto the bandwagon shouting "I want a piece of that action!" and there is absolutely nothing the original company can do about it, except try to show that their original molecule is better than the new competitors and to try and build a substantial market share before everyone switches to the new derivative. (Prescribers are human and tend therefore to be lazy, so unless there's a reason to change, the class leader will still have substantial share even after several derivatives exist.)

It's an arms race - each company tries to create as many of these potential "me-too" variants as possible in-house, put as many as can be (financially) supported through trials, keep pursuing those which don't have prohibitive side-effects / problems in tests and hope that, at the end, one of their versions will actually turn out to have better effectiveness or fewer side-effects. If not, they just have to market one as "as-effective-and-no-more-harmful-but-CHEAPER-than" the class leader. The majority of "me-too" molecules come under this category - even if the company concerned would try to point to infinitesimal differences in trial data to pretend otherwise. All this with the knowledge that the very hour that the patent expires, a dozen generic manufacturers will flood the market with copies which do not need to recover the massive costs of the original research and are therefore massively cheaper.

How much cheaper? patented molecules may cost 30 for 28 doses on Monday and one generic may cost 3p for 500, another may cost 40p for 10,000 on Tuesday, the day after the patent expiry. Generic houses only need to cover the actual costs of manufacture, not the costs of the original patent etc. and by the time the patent expires, the efforts of the patent holder to generate market share mean that economies of scale become evident. The absolute cheapest isn't necessarily the one who gets the contract either, these things all have expiry dates and all 10,000 have to be sold / supplied from a single location within that date to actually deliver the full savings. So then you get satellite generics who buy in quantities of a few million and pack down into 56 or less so that the total purchased quantity can sit on many shelves instead of just one. It's the same tablet in the end, with the same markings too. All that differs is the marking on the foil and the colour of the cardboard. (Oh and the same foil and colour cardboard can contain tablets with different markings from different manufacturers from one batch to the next, all within the branding of the same repackaging company.)

The original patent-holding company also has an interest in generating their own "me-too" derivatives, sometimes marketed under the name of a company which turns out to be solely owned by the parent of the original company. It can get horribly recursive.
Sometimes, the derivative from the sibling company hits the market before the "true" competitor from a different company - simply because all companies try to have many molecules in development at any one time (because most changed molecules fail in testing) and sometimes they get lucky and come up with two v.similar molecules and have to do something to justify the cost of developing both. That can turn out to be a poisoned chalice rather than two golden geese.

Sometimes, the company fails to get enough variants through testing and the company then gets bought out by a rival - who then gains their research and continues experimenting with other derivative molecules based on the ones already tested and dismissed. The limiting factor is the money.

At this point, I must now declare my cards. I used to be a pharmacist and although I am still entitled to call myself the holder of a Batchelor of Sciences degree in Pharmaceutical Sciences I am most definitely no longer a pharmacist. I therefore defer to my still-registered colleagues in case I've messed up any of the detail here. The above cannot be declared as the opinion of a pharmacist. I am an ex-pharmacist who voluntarily chose to resign his registration to take up full time work as a software developer rather than pay the exorbitant costs of maintaining such registration and all the "proof-of-competency" requirements which such registration requires.

Finally, before you ask, I am very happy to be an ex-pharmacist - my erstwhile colleagues have my ongoing sympathy but no matter how much some of them may beg, they all know that I will not be rejoining them on that side of the dispensary bench if I've got any choice in the matter.

Software is just better. It's all just recycled electrons.

February has been again a busy month for me. Here s a quick summary of what I did: Multi-Arch work I have spent many days implementing and refining dpkg s Multi-Arch support with Guillem Jover (dpkg co-maintainer) and Steve Langasek (beta-tester of my code ). Early testers can try what s in my latest pu/multiarch/snapshot/* branch in my personal git repository. A Debian DVD shop I m always exploring new options to fund my Debian work (besides direct donations) and this month with the Debian Squeeze release I saw an opportunity in selling Debian DVD. Nobody provides DVD with included firmwares and quite a few people would like to avoid the SpaceFun theme. So I built unofficial Debian DVDs that integrate firmware and that install a system with the old theme (MoreBlue Orbit). Click here to learn more about my unofficial DVDs. On my blog In my People behind Debian series, I interviewed Mike Hommey (Iceweasel maintainer) and Maximiliam Attems (member of the kernel team). I started a Debian Cleanup Tip series and already published 4 installments:

• Debian Cleanup Tip #1: Get rid of useless configuration files
• Debian Cleanup Tip #2: Get rid of obsolete packages
• Debian Cleanup Tip #3: Get rid of third-party packages
• Debian Cleanup Tip #4: Find broken packages and reinstall them

For contributors, I wrote two articles: the first gives a set of (suggested) best practices for sponsoring Debian packages and adapted my article as a patch for the Developers Reference. In the second article, I shared some personal advice for people who are considering participating on Debian mailing list: 7 mistakes to avoid when participating to Debian mailing lists.

Continuing my series about a desktop in a shell, today I will present you my mutt setup. I use mutt because it has no bugs and is a really good MUA for people loving consoles ;)First of all you have to know, that all my mail is forwarded to my server and sorted into Maildirs via maildrop, so I do not care about sorting on my desktop , which just fetches the mail via IMAP from the server ;)I m running mutt-patched from Debian Squeeze, so not all options may be available for you if you do not have the same patchset as I do.First, tell mutt to fetch mail from imap.die-welt.net via IMAP:

set imap_user=username
set imap_pass=password
set folder="imaps://imap.die-welt.net/INBOX"
set spoolfile="imaps://imap.die-welt.net/INBOX"

Now, enable IMAP-IDLE, list subscribed folders, reconnect to the server if needed and mark mail as read when you open it:

set imap_idle
set imap_check_subscribed
unset imap_passive
unset imap_peek

Let mutt save sent mail to the Sent directory on the IMAP server, and postponed mail to Drafts:

set record=+Sent
set postponed=+Drafts

Read mail should stay where it is:

set mbox="!"

We use IMAP-IDLE, thus check for new mail manually only every 90 seconds:

set mail_check=90

Instead timeout after 15 seconds if no user input is given:

set timeout=15

Set default mail from address to my default mail address:

set from=evgeni@golov.de

And send mail via mstmp (see below for mstmp configuration):

set sendmail="/usr/bin/msmtp"

Tell mutt which addresses I recieve mail to (danger, ugly regex!):

alternates (evgeni@(debian.org golov.(de eu)) sargentd@(die-welt sargentd).net evgeni.golov@uni-duesseldorf.de)

As mutt knows where I receive mail, let it set From accordingly:

set reverse_name

Let mutt cache some stuff and find its certificates:

set header_cache="~/.mutt/cache/headers"
set message_cachedir="~/.mutt/cache/bodies"
set certificate_file=~/.mutt/certificates
set ssl_ca_certificates_file=/etc/ssl/certs/ca-certificates.crt

Show only interesting headers in an useful order:

ignore headers *

Fix stupid MUAs behaviour (e.g. filenames like =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=):

set rfc2047_parameters

Beep on new mail, will generate a ! in the window name in screen:

mutt-patched has the great sidebar patch, assign ctrl-n, ctrl-p to select next, prev folder, ctrl-o to open selected folder:

bind index \Cp sidebar-prev
bind index \Cn sidebar-next
bind index \Co sidebar-open

And toggle sidebar visibility with ctrl-b:

macro index \Cb '<enter-command>toggle sidebar_visible<enter><refresh>'
macro pager \Cb '<enter-command>toggle sidebar_visible<enter><redraw-screen>'

Since 1.5.20-2, mutt patched contains my sidebar-dotted and sidebar-sorted patches.
Let mutt shorten the displayed path (e.g. debian-devel instead of INBOX.ml.debian-devel) and sort the folders (the are returned in random order when using imap_check_subscribed):

set sidebar_shortpath
set sidebar_sort

Now let s set some colors (that match the rest of my desktop ):

color sidebar_new yellow default
color normal white default
color hdrdefault brightcyan default
color signature green default
color attachment brightyellow default
color quoted green default
color quoted1 white default
color tilde blue default

And add some useful macros for marking new and old messages as read:

macro index .n "<tag-pattern>~N<enter><tag-prefix><clear-flag>N<clear-flag>*" "Catchup all new messages"
macro index .o "<tag-pattern>~O<enter><tag-prefix><clear-flag>O<clear-flag>*" "Catchup all old messages"

When forwarding mail, I like it to be forwarded as an attachment (YMMV):

set mime_forward=yes

I m using goobook in mutt to fetch my addressbook from Google. As there is no Debian package for goobook (yet), you have to install it yourself (via easy_install):

apt-get install python-argparse python-gdata python-simplejson python-keyring python-nose
easy_install goobook

Configuration is easy via ~/.goobookrc:

[DEFAULT]
# If not given here, email and password is taken from .netrc using
# machine google.com
email: me@gmail.com
password: password

And then add the following to your .muttrc:

set query_command="goobook query '%s'"
bind editor  complete-query
macro index,pager a "<pipe-message>goobook add<return>" "add the sender address to Google contacts"

That s all for mutt, but We are running mutt in a screen, so let s add the following to .screenrc to fix transparency and cut&paste (see http://wiki.mutt.org/?MuttFaq/Appearance):

 defbce on
 term screen-bce

And as mutt uses mstmp (yes, I know, mutt can handle SMTP itself ), this is my .msmtprc:

defaults
domain dorei.kerker.die-welt.net
tls on
account die-welt.net
host smtp.die-welt.net
from sargentd@die-welt.net
auth on
user username
password password
tls_starttls on
tls_certcheck off
# Set a default account
account default : die-welt.net

C est tout! That is my personal mutt configuration, you can download it as one file here: my .muttrc. And as everyone loves screenshots, here is one:Oh, the next chapter will be about irssi, but not before next Sunday (March 6th) as I ll be offline for a week, skiing in Austria :)

You re eager to start contributing to Debian, your first action is to subscribe to some high-profile mailing lists (like debian-devel and debian-project) to get a feel of the community. You read the mails for a few days and then you find out that you could participate to the discussions, it s a simple first step after all. True enough. That said, it s not as easy as it looks like. There are many mistakes that you should avoid:

1. Don t fall in the trap where your mailing list participation is your sole contribution to Debian. If you want people to give credit to your messages, you should already be doing something else for Debian.
2. Don t participate more than once a day to a given thread. There are many people subscribed, you should leave room for other people to express their point of view. You can always follow up one day after and reply to several messages at once if you believe you still have something new to add to the discussion.
3. Don t reply to off-topic threads. Someone asked a simple question and someone else pointed out that his message was off-topic. Don t reply, or if you really need to, do it on the correct list or with a private response.
4. Don t ask questions unless it s useful to bring the discussion forward. Development lists are not here to fill the gaps in your knowledge. We already have debian-mentors for this. Furthermore there s no better way to learn than to find yourself the answers to your questions.
5. Don t believe your opinion is so important. We re all very opinionated and discussions that consist only of contradicting opinions tend to go nowhere. Thus don t give your opinion unless you can back it up with new facts or another experience.
6. Don t participate to all threads. There are surely some topics where you are more knowledgeable than others, participate where you add the most value and leave the others threads to the other experts (and learn by reading them).
7. Don t hide your identity. In Debian we like to know each other. Use your real name and not some anonymous nickname. You need to be able to stand up behind your words, otherwise you re not credible.

I have myself been guilty of several of those when I started I invite you to follow my recommendations to ensure our mailing lists remain pleasant to read and an effective discussion place.

You should follow me on Identi.ca, Twitter and Facebook. Or subscribe to this blog by RSS or by email.

There are many ways to run some commands simultaneously on multiple hosts like cssh or dsh. They come handy for example when you are installing software updates on a set of hosts. dsh is a rather simple comandline tool allowing to execute a command over ssh on multiple hosts. However it doesn't allow any interactive input -- so you can't look at the potentially upgrading packages and press y to accept and you can't go through debconf promts or similar. This is solved by cssh which opens a XTerm for every host and a input area that is broadcastet to all of them. this is working really well -- you can execute your update on all hosts and still do individual adjustments just as needed: switch focus from the broadcasted input to one of the terminal windows and anything you type just goes there. Now cssh has a big disadvantage: it requires a running X server (and doesn't do too well with a fullscreen windowmanager). Requiring X is quite a blocker if you need to run that ssh multiplexer on a remote host, for example if the firewalling doesn't allow direct connections. Fortunately you can make tmux behave as we want -- in a simple terminal: First you need a script spawning the ssh sessions in separate tmux panes and direct input to all of them -- here called ssh-everywhere.sh (you could also write a tmux config I guess):

#/bin/sh
# ssh-everywhere.sh
for i in $HOSTS
do
  tmux splitw "ssh $i"
  tmux select-layout tiled
done
tmux set-window-option synchronize-panes on

Now start the whole thing:

tmux new 'exec sh ssh-everywhere.sh'

And be done. Update If you want to type in just one pane (on one host) you can do that as well: C-b : set-window-option synchronize-panes off and moving to the right pane (C-b + Arrow keys)

Maximilian, along with the other members of the Debian kernel team, has the overwhelming job of maintaining the Linux kernel in Debian. It s one of the largest package and certainly one where dealing with bug reports is really difficult as most of them are hardware-specific, and thus difficult to reproduce. He s very enthusiastic and energetic, and does not fear criticizing when something doesn t please him. You ll see. My questions are in bold, the rest is by Maximilian. Who are you? My name is Maximilian Attems. I am a theoretical physicist in my last year of PhD at the Technical University of Vienna. My main research area is the early phase of a Quark-Gluon Plasma as produced in heavy ion collisions at the LHC at CERN. I am developing simulations that take weeks on the Vienna Scientific Cluster (in the TOP 500 list). The rest of the lab is much less fancy and boils down to straight intel boxes without any binary blobs or external drivers (although lately we add radeon graphics for decent free 3D). Mathematica and Maple are the rare exceptions to the many dev tools of Debian (LaTeX, editors, git, IDE s, Open MPI, ..) found at the institute, as those are unfortunately yet unmatched in Free Software for symbolic computations. The lab mostly runs a combination of Debian stable (testing starting from freeze) for desktops and oldstable/stable for servers. Debian is in use for more than 10 years. So people in the institute know some ups and downs of the project. Newcomers like my room neighbors are always surprised how functional a free Debian Desktop is. What s your biggest achievement within Debian? Building lots and lots of kernels together with an growing uptake of the officially released linux images. I joined the Debian kernel team shortly after Herbert Xu departed. I had been upstream Maintainer of the linux-2.6 janitor project for almost a year brewing hundreds of small cleanups with quilt in a tree named kjt for early linux-2.6. In Debian we had lots of fun in sorting out the troubles that the long 2.5 freeze had imposed: Meaning we were sitting on a huge diverging monolithic semi-good patchset. It was great fun to prepare 2.6.8 for Sarge with a huge team enthusiastic in shipping something real close to mainline (You have to imagine that back then you had no stable or longterm release nor any useful free tools like git. This involved passing patches around, hand editing them and seeing what the result does.) From the Sarge install reports a common pattern emerged that the current Debian early userspace was causing lots of boot failures. This motivated me to develop an alternative using the new upstream initramfs features. So I got involved in early userspace. Thanks to large and active development team initramfs-tools got a nice ecosystem. It still tries to be as generic and flexible as possible and thus gains many nice features. Also H. Peter Anvin (hpa) gave me the official co-maintenance of klibc. klibc saw uptake and good patches from Google in the last 2 years. I am proud that the early userspace is working out fairly well these days, meaning you can shuffle discs around and see your box boot. Later on we focused on 2.6.18 for Etch, which turned out to a be good release and picked up by several other distributions. Only very much later we would see such a sync again. With 2.6.26 for Lenny we got somehow unlucky as we just missed the new longterm release by one release. We also pushed for another update very late (during freeze) in the release cycle, which turned out to semi-work as too much things depend on linux-2.6. For Squeeze 2.6.32 got picked thanks to discussions at Portland Linux Plumbers and it turned out to be a good release picked up by many distributions and external patchsets. The long-term support is going very well. Greg KH is doing a great job in collecting various needed fixes for it. Somehow we had hoped that the Squeeze freeze would start sooner and that the freeze duration would be shorter, since we were ready for a release starting from the actual freeze on. The only real big bastard on the cool 2.6.32 sync is Red Hat. Red Hat Enterprise 6.0 is shipping the linux-2.6 2.6.32 in obfuscated form. They released their linux-2.6 as one big tarball clashing with the spirit of the GPL. One can only mildly guess from the changelog which patches get applied. This is in sharp contrast to any previous Red Hat release and has not yet generated the sharp and snide comments in press it deserves. Red Hat should really step back and not make such stupid management moves. Next to them even the semi-maintained Oracle Unbreakable 2.6.32 branch looks better: It is git fetchable. What are your plans and those of the kernel team for Debian Wheezy? Since 2.6.32 many of the used patches landed upstream or are on the way (speakup, Kbuild Debian specific targets, ..). The proper vfs based unionfs is something we d be looking forward. We haven t yet picked the next upstream release we will base Wheezy on, so currently we can happily jump to the most recent ones. There are plans for better interaction with Debian Installer thanks to generating our udebs properly in linux-2.6 source itself. Also we are looking forward to using git as tool of maintenance. We d hope that this will also allow for even better cross distribution collaboration. Concerning early userspace I plan to release an initramfs-tools with more generic userspace for the default case and finally also a klibc only for embedded or tuning cases. What do you like most in Debian? For one thing I do like the 2 year release cycle. It is not too long to have completely outdated software and on the other hand it gives enough time to really see huge progress from release to release. Also at my institute the software is is recent enough without too much admin overhead. For servers the three years support are a bit short, but on the manageable side. I do enjoy a lot the testing distribution. For my personal use it is very stable and thus I mainly run testing on my desktop and work boxes. (Occasionally mixing in things from sid for unbreaking transition or newer security fixes). Debian is independent and not a commercial entity. I think this is its main force and even more important these days. I enjoy using the Debian platform a lot at work thus in return this motivates me to contribute to Debian itself. I also like the fact that we strive for technical correctness. Is there some recurrent problem that hinders the progress of Debian? The New Maintainer process is a strange way to discourage people to contribute to Debian. It is particularly bureaucratic and a huge waste of time both for the applicant and his manager. It should be completely thrown overboard. One needs a more scalable approach for trust and credibility that also enhances the technical knowledge for coding and packaging of the applicant. NM is currently set in stone as any outside critics is automatically rejected. Young and energetic people are crucial for Debian and the long-term viability of the project, this is the reason why I d consider the New Maintainer process as Debian s biggest problem. Note from Rapha l Hertzog: I must say I do not share this point of view on the New Maintainer process, I have witnessed lots of improvements lately thanks to the addition of the Debian Maintainer status, and to the fact that a good history of contribution can easily subsume the annoying Tasks & Skills questionnaire. Another thing I miss is professional graphics input both for the desktop theme and the website. I know that effort has been done there lately and it is good to see movement there, but the end result is still lacking. Another trouble of Debian is its marketing capabilities. It should learn to better sell itself. It is the distribution users want to run and use not the rebranded copies of itself with lock-in sugar . Debian is about choice and it offers plenty of it: it is a great default Desktop. Linus Torvalds doesn t find Debian (and/or Ubuntu) a good platform to hack on the kernel. Do you know why and what can we do about this? The Fedora linux-2.6 receives contributions from several Red Hat employed upstream sub-Maintainers. Thus it typically carries huge patches which are not yet upstream. As a consequence eventual userland troubles get revealed quite quickly and are often seen there first. The cutting edge nature of Fedora rawhide is appealing for many developers. The usual Debian package division of library development files and the library itself is traditionally an entry barrier for dev on Debian. Debian got pretty easily usable these days, although we could and should again improve a lot more in this sector. Personally I think that Linus hasn t tried Debian for years. I have the feeling that the implication of the Debian Kernel team in LKML has been on the rise. Is that true and how do you explain this? Ben Hutchings is the Nr.1 contributor for 2.6.33. He also is top listed as author of patches on stable 2.6.32. Debian is not listed as organization as many send their linux-2.6 patches from their corporate or personal email address and thus it won t be attributed to Debian. There is currently no means to see how many patches get forwarded for the stable tree, but I certainly forwarded more then fifty patches. I was very happy when Greg KH personally thanked me in the 2.6.32.12 release. In the Squeeze kernel, the firmwares have been stripped and moved into separate packages in the non-free section. What should a user do to ensure his system keeps working? There is a debconf warning on linux-2.6 installation. It is quite clear that the free linux-2.6 can t depend on the firmware of the non-free archive (also there is no strict dependency there technically). On the terminal you d also see warnings by update-initramfs on the initramfs generation for drivers included in the initramfs. The debconf warning lists the filename(s) of the missing firmware(s). One can then apt-cache search for the firmware package name and install it via the non-free repository. The check runs against the current loaded modules. The match is not 100% accurate for special cases as the one where the device might be handled well by this driver without firmware, but is accurate enough to warrant the warning. The set of virtualization technologies that the official Debian kernel supports seems to change regularly. Which of the currently available options would you recommend to users who want to build on something that will last? KVM has been a smooth ride from day zero. It almost got included instantly upstream. The uptake it has is great as it sees both dev from Intel and AMD. Together with libvirt it s management is easy. Also the performance of virtio is very good. The linux containers are the thing we are looking forward for enhanced chroots in the Wheezy schedule. They are also manageable by libvirt. Xen being the bad outside boy has an incredible shrinking patchset, thus is fair to expect to see it for Wheezy and beyond. For many it may come a bit late, but for old hardware without relevant CPU it is there. Many tend to overstate the importance of the virtualization tech. I d be much more looking forward to the better Desktop support in newer linux-2.6. The Desktop is important for linux and something that is in heavy use. The much better graphics support of the radeon and nouveau drivers:

• For Nouveau in 32 with 33 drm we could only deliver a first taste meaning something better then rusty nv.
• For Radeon the support for Evergreen and newer is only been shaping now.

The performance optimizations thanks to dcache scalability work and the neat automatic task-grouping for the CPU scheduler are very promising features for the usability of the linux desktop. Another nice to have feature is the online defrag of ext4 and its faster mkfs. Even cooler would be better scalability in ext4 (This side seems to have seen not enough effort lately). Is there someone in Debian that you admire for their contributions? Hans Peter Anvin and Ted Tso are a huge source of deep linux-2.6 knowledge and personal wisdom. I do enjoy all sorts of interactions with them. Christoph Hellwig with Matthew Wilcox and also William Irwin for setting up the Debian kernel Team. Several Debian leaders including the previous and the current one for their engagement, which very often happens behind the scene. The Debian Gnome Team work is great, also the interactions have always been always easy and a pleasure. Martin Michlmayr and previously Thiemo Seufer do an incredible job in porting Debian on funny and interesting ARM and MIPS boxes. Debian has a lot of upcoming potential on this area. I m looking forward to other young enthusiastic people in that area. Colin Watson is bridging Debian and Ubuntu, which is an immense task. Michael Prokop bases on Debian an excellent recovery boot CD: http://www.grml.org. I d be happy if any Debian Developer would work as carefully coding and working.

Using a virtual IP managed by heartbeat is a nice way to work around the slow fallback behavior with multiple nameservers in /etc/hosts. But unlike ntpd, bind9 doesn't automatically listen on new IPs on the system. Here's a cute hack to fix that:

# cat /etc/ha.d/haresources
server01 bind9release IPaddr::10.0.0.3 bind9takeover
# cat /etc/ha.d/resource.d/bind9release
#!/bin/sh
# when giving up resources, reload bind9
case $1 in
        stop) /etc/init.d/bind9 reload ;;
esac
exit 0
# cat /etc/ha.d/resource.d/bind9takeover
#!/bin/sh
# on takeover, reload bind9
case $1 in
        start) /etc/init.d/bind9 reload ;;
esac
exit 0

A new release 0.9.1 of Rcpp went to CRAN and Debian yesterday. This version contains mostly bug-fixes and rather few enhancements. The changes are mostly 'internal fixes' and not user-facing; they mostly address some issues in memory management which, while not tripping up the unit tests or common usage, caused trouble for advanced Rcpp modules use and repeated memory allocation / deallocation. This bit Doug Bates repeatedly, and he put his head down and debugged the issue. A number of changes fairly deep-down in Rcpp (as well as in R-devel) later, this looks much better and we owe him a hearfelt Thank You! A big Thanks! also goes to Luke Tierney who out some new memory debugging code into R-devel which the --enable-strict-barrier in R 2.13.0 (due in April) will enable. A related fix is also in R 2.12.2 due on the 25th. The NEWS entry is below; more detail is in the ChangeLog file in the package.

0.9.1   2011-02-14
    o   A number of internal changes to the memory allocation / protection of
        temporary objects were made---with a heartfelt "Thank You!" to both
        Doug Bates for very persistent debugging of Rcpp modules code, and to
        Luke Tierney who added additional memory allocation debugging tools
        to R-devel (which will be in R 2.13.0 and may also be in R 2.12.2)
        
    o   Removed another GNU Make-specific variable from src/Makevars in order
        to make the build more portable; this was noticed on FreeBSD
    o   On *BSD, do not try to compute a stack trace but provide file and
        line number (which is the same behaviour as implemented in Windows)
    o   Fixed an int conversion bug reported by Daniel Sabanes Bove on r-devel,
        added unit test as well
    
    o   Added unit tests for complex-typed vectors (thanks to Christian Gunning)
    
    o   Expanded the Rcpp-quickref vignette (with thanks to Christian Gunning)
    o   Additional examples were added to the Rcpp-FAQ vignette

Thanks to CRANberries, there is also a diff to the previous release 0.9.0. As always, even fuller details are on the Rcpp Changelog page and the Rcpp page which also leads to the downloads, the browseable doxygen docs and zip files of doxygen output for the standard formats. A local directory has source and documentation too. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page

On the gripping hand, Matthew, notice that patches written by someone utterly unfamiliar with the code in question aren't always welcome. While some people don't mind spending several days on something that may or may not be accepted to begin with, it's important to realize that talking about wishlist items before even thinking about possibly writing a patch is more likely to result in the desired behaviour than writing and submitting patches in a fire-and-forget manner. In that light, there are cases where 'please send a patch' can be quite demotivating, and it makes sense as a developer to engage in a discussion about a wishlist item, even if you're not immediately interested in implementing said feature yourself. Such a discussion could lead to either you implementing it, or someone else implementing it, or the other person finally understanding that your vision for the software in question doesn't match theirs, and that they should just find something else to spend their time on. I guess the moral of the story is: as a user with a wishlist item, you should talk to developers, let them know what you think is important, and be prepared to write a patch yourself if needs be and you have the skill. As a developer, you shouldn't interpret every wishlist request as a question to 'please please please implement my pet feature', but as an opportunity to reconsider your views, and possibly implement some nice new feature that you hadn't thought about originally but which you think might be nice, too. If people reply with 'please provide a patch' to each and every wishlist request, they're stupid; even more so than users who think they have anything to demand.

Part of the motivation for creating that site was that a lot of them tend to contain one good idea, and an inordinate amount of fluff. This book does not - it's good material that could not easily be summarized because it's full of information. I think it's actually one of the more relevant books I've ever read in that, for my situation, the idea behind it really speaks to me. I work as a consultant during the days, and I like it a lot. Rather than working on the same old thing year after year, I get to meet new people, new clients, new situations, and help them out, which is motivating. However, consulting has its downsides too, in that it doesn't create a great deal of long-term value. Once you've finished up a project, it's on to the next one, or no money comes in. I'm also a bit older and more set in my ways: I did my time in the California Bay Area, and I don't relish going back and working like mad on a "Real Startup" with VC backing, crazy hours, and having the thing consume my life. The idea behind "Start Small, Stay Small" is to find and create really niche products: stuff that will earn you some extra money as a developer, but also niches that are small enough to not really be interesting to larger companies that need a lot of income to justify a forray into a particular market segment. This, then, becomes your 'competitive advantage': Microsoft, or even 37 Signals, simply isn't going to chase after a market that is worth 20,000 dollars a year. And yet for someone working on their own, if you manage to set up something that brings in that money, and mostly automate it so that it's not a second job, it's a tidy extra bit of money. Several projects like that might even be enough to live on, depending on your lifestyle. With that in mind, the authors, Rob Walling and Mike Taper, delve into the details of how to go about doing so. The whole thing is done under the assumption that you don't have a lot of time or money to throw at things that don't bring in concrete results in relatively short order. Various subjects discussed in detail include how to find a niche, how to create a sales web site, how to measure market demand, conversion rates, how to productively outsource less critical portions of your business, and much more. They also discuss what sorts of numbers to look at for various aspects of the business, and anchor the discussion with real numbers for many things, rather than just giving you a hand-wavy phrase that's not that useful in the real world. It's not a 'timeless' book as all the concrete numbers and techniques reference technologies, sites, and the market dynamics of 2011, but after all, that's part of what makes it good. Other things I didn't like so much were being sold on their for-pay "micropreneur community", and the relatively high price of the book but I think it's worth it given the real advice you get. If you don't like marketing, and think that products succeed or fail on their merits alone, of course the book will leave you cold, but of course you're wrong about that anyway!

The first day of GNUnify 11 has passed. My talk on Haskell went, as far as I can tell, well. Attendance was good (rough estimate: just above 50), although it was not as packed as later talks, and there some questions being asked. There were some technical problems with the microphone, I m not sure how that affected the people sitting in the rear rows. Also, I fear that the video recording of the talk might have suffered we will see. Later throughout the afternoon and evening I would repeatedly find myself cornered by five to ten students of SICSR who would question me about Haskell (Why should I learn it, where is it used, how is different from Java?) mostly volunteers who were busy and thus unable to attend the session. I think I got some of them at least curious about Haskell. I did attend a talk on virtualization and a short demo of GNOME 3 and otherwise just talked to people or sat in the speakers corner. The pampering by the organizers continued if I would stand for half a second with a slightest, even false, hint of help-needing on my face, they would ask me if I need any thing. When I pass they would step back to free the path. It made me feel a bit uneasy, but I figured that normal behavior in the Indian culture and they, being hosts to me, would not feel comfortable any other way. We had dinner at the side of the pool of the Symbiosis university, and more interesting talk happened. So far, nobody seemed to be interested in GPG keysigning, maybe I should give a talk about GPG and the web of trust next time.

A while ago (early 2009), I created whiteboard.debian.net as a way to do real-time editing collaboration. While working for DebConf, I really wanted to be able to collaboratively edit text with people, and all of the web-based solutions I found at the time were non-free. Thus, I took mobwrite and wrote a very thin wrapper around it. Mobwrite is where all the cleverness is (and mobwrite is way beyond my expertise, by the way). Mobwrite is Apache licensed, so you can use it in other places, too.Thus, whiteboard.debian.net was begun. It was never publicized very much. It has no authentication required and no history (the "static link" does provide limited recovery for mistakes, though). Here is a test whiteboard; open it in two tabs and watch the text areas sync. Any whiteboard is created if you go to a valid URL.I just deployed a slightly newer version of whiteboard. You can now see an options page for each whiteboard, and it can render in several lightweight markup languages (good for drafting+previewing things). If you have other options to add there, let me know.If you are interested in collaborative text editing, there are some other options. There is a Debian titanpad, an "open" instance of now-open-sourced Etherpad, and it has history support. Use titanpad.com and you don't have to log in. Here is a test pad. For a non-web application, Gobby exists. Use gobby-0.5 for smart undo history if everyone uses squeeze or above.Is whiteboard still relevant in light of the options above that store history? I'm sure it depends, but for now, whiteboard works well for a low-overhead scratch space and for cases where you don't want to have a history trail. I also tend to use it as a simple pastebin or a personal notepad when I don't want to worry about having traces left behind. In short, it is so minimal you don't have to think about starting one up for something. I have found that collaborative writing really helps to get things done, thus, I hope that whiteboard (or a similar tool) can be useful to you.

The Ubuntu website states that we aim to make Ubuntu a wonderful place to participate . We developed the Ubuntu Code of Conduct to set a standard for participants to accept each other in the spirit of cooperation, and have improved it over time to state these principles more clearly. It is implicit in our philosophy that these and other Ubuntu values should hold equally true for everyone. I would like to propose that we upgrade this to an explicit statement on behalf of the project. I have spoken with many people who were interested in joining a free software project, but were put off because they felt unwelcome. I know various people who participate in Ubuntu today, but sometimes face difficult social obstacles in order to do so. Going forward, I would like for us, as members of the Ubuntu community, to make the extra effort to accept all kinds of people. This may sound simple, but it can be very difficult to put into practice. People often don t even notice they ve gotten it wrong, until the offended party points it out to them. We need tools and guidance to make this a reality. To that end, I would like to propose a diversity statement for Ubuntu. This draft has already received support from a majority of the Community Council, but I d like to take it a step further. Because I want this to be a commitment that we can all stand behind, I m also calling for support from the community as a whole. Please give this issue your consideration, and let me know in the comments if you can get on board with an official statement like this. The more support we have, the more real this commitment can be. Here s the text. Many thanks to Mary Gardiner, Valerie Aurora and Benjamin Mako Hill for their review and input.

The Ubuntu project welcomes and encourages participation by everyone. We are committed to being a community that everyone feels good about joining. Although we may not be able to satisfy everyone, we will always work to treat everyone well. Standards for behavior in the Ubuntu community are detailed in the Code of Conduct and Leadership Code of Conduct. We expect participants in our community to meet these standards in all their interactions and to help others to do so as well. Whenever any participant has made a mistake, we expect them to take responsibility for it. If someone has been harmed or offended, it is our responsibility to listen carefully and respectfully, and do our best to right the wrong. Although this list cannot be exhaustive, we explicitly honor diversity in age, culture, ethnicity, genotype, gender identity or expression, language, national origin, neurotype, phenotype, political beliefs, profession, race, religion, sexual orientation, socio-economic status, subculture, and technical ability. Some of the ideas and wording for this statement were based on diversity statements from the Python community and Dreamwidth Studios (CC-BY-SA 3.0).

(This is part of a series of posts on Why Linux?) I think of myself as reasonably pragmatic in my approach to Free/Open Source software. I don't get worked up over which set of language people want to use. I use devices that require binary firmware to be downloaded to them (because just because I can't see it doesn't mean it doesn't exist). I have non-free in my sources.list. And yet, talking to other Linux users these days, I realize I'm much more of a Freedom nut job than average. I want the source, be it for a driver, a minor widget, or a full app. I don't buy nVidia. I will sacrifice a degree of functionality in order to get Free. And while I think WINE is an excellent piece of software, I think the best end result is that it's no longer necessary, not that it's a perfect implementation of the ABI. How does any of this help justify my use of Linux in the work place? As previously mentioned, I'm a developer. Most developers don't operate in a vacuum; they have to inter-operate with other ecosystems. And usually somewhere along the line there's a failure to document exactly how something is handled, or an ambiguity about what exact choice might be taken. If I have access to the source then I can check that out for myself. If I don't, I have to guess. As an example, a long time ago I was involved in writing a serial console driver for QNX. There came a point where the behaviour wasn't quite as we'd expect. Although the organisation had a license for the source, I wasn't allowed to look at it. Instead I had to come up with a series of suitable questions that someone who could look at the source could answer without violating any NDAs. If I'd been able to look at the source directly we'd have all saved a lot of time. And that's an example where someone could look at the source, rather than having to make a bunch of guesses and instrument tests to see which was right. Access to the Linux source has helped me in other commercial contexts too. At Black Cat we were able to take advantage of patches like grsecurity in order to tighten up shell account boxes. I wrote the IPv6 support for l2tpns, because we had access to the source and could. I've been able to look at the source to understand exactly what SCSI responses are sent in certain circumstances too (or understand exactly what the error that a user land test program was getting back meant). Also I'm a big believe in Linus' Law. I do think that good Free software is much better than proprietary software (there's some really bad Free software out there though, I'm not disputing that). The fact that smart people can look at it and scratch whatever their itch is means that we get a gradual process of improvement that can't be ignored. Equally as long as someone has an interest in the software, end users can't be left high and dry by organisations abandoning still users applications. I think that should be a powerful driver to business to look towards Free software. (Before my more astute readers point it out; yes, I am employed writing non-free software. See the first sentence. One day I'll find a job working on Free software that ticks enough of the other boxes to be viable.)

It's been reported for some time now that the number of active editors on Wikipedia (usually defined as people who have edited at least 5 times in a given month) peaked in 2007 and has been mostly stable since then. A graph of the total number of active editors in every month since Wikipedia's founding is shown below. The graph shows the aggregate numbers for all language Wikipedias. English Wikipedia is the largest component of this and is generally more variable. That said, very similar patterns exist for most larger languages. Felipe Ortega, who has provided many of these statistics, has warned against fatalist claims. Although there seems to be a decrease in the total number of active editors over the last two years, the situation seems to have somewhat stabilized in most languages. New editors in Wikipedia are replacing folks at almost the rate that they are leaving. It is also widely known that the number of readers of Wikipedia has been increasing during this period. According to the report cards released by the foundation using comScore data, the number of unique visitors to Wikipedia each month has increased by 61 million people in the last year -- over 17%. This discrepancy between rising readership and stable or sinking editorship should raise major concern. After all, the Wikimedia Foundation's mission is two part: (1) to empower and engage people around the world to collect and develop educational content and (2) to disseminate it effectively and globally. Although the Foundation report cards include measures of raw levels of editorship, a better metric of engagement and empowerment might be the proportion of readers who engage in editing. I could not find reliable data on the number of unique readers reached each month for more than a few months in the last year. What is available, however, is wonderful data on page views each month going back to 2008. Analysis of the data from available report cards show that, at least during the last year, there is a very stable ratio of 35 page views per unique visitor, as estimated by comScore. Using that measure, we can do a back of the envelope estimation on the proportion of users that are editors for the period where page view data is available, dating back from February 2008 ( marked with the grey dashed lined above). The graphs below show the very different results you get when you consider the change in the number of Wikipedia editors and the change in the editor-to-reader ratio. Once again, these data are combined data for all language Wikipedias although graphs look very similar for most larger languages. The results are striking. Although there has been a 12% decrease between February 2008 and December 2010 in the number of active editors, there is a 42% decrease in the proportion of readers who edit at least five times a month. We can see that fulfilling the first half of the Wikimedia mission remains a struggle. Although the graphs above do not say anything directly about the most active core contributors to Wikipedia, the fact that Wikipedia is being maintained by a tiny -- and shrinking -- proportion of its readership does mean that the idea behind Wikipedia is under threat. Although none are as big as Wikipedia, there are lots of good encyclopedias out there. The reason Wikipedia is different, interesting, and important is because -- unlike all those others -- Wikipedia is the encyclopedia that anyone can edit. Wikipedia is powerful because it allow its users to transcend their role as consumers of the information they use to understand the world. Wikipedia allows users to define the reference works that define their understanding of the their environment and each other. But 99.98% of the time, readers do not transcend that role. I think that's a problem. Worse, that the number is growing. The Wikimedia Foundation recently ran a major successful effort to attract donations in its annual fundraiser. Jimmy Wales' smiling mug is apparently enough in the way of motivation to get something like 1% of its readers to donate money to support the project. I think that's very good news. If the Wikimedia community can entice even half of those people to contribute through an increased involvement in the projects themselves, they might do more than ensure Wikipedia's continued growth. They would help take a step toward the empowerment and engagement of those users in sharing their own knowledge, and the continued fulfillment of a critically important mission.

I just got a Zoom 5341 modem to replace a very sketchy old Motorola model and so far it seems to work fine. However, the Comcast self-install switch process was not seamless. After you plug your new modem in the process starts fine, capturing your session and prompting you for your account. However at the next step it prompts you to download the Windows or Mac only client, directing you to an address http://cdn/.... It is at this point you can get stuck if you're behind a Netgear router (I have a WNDR3700) and probably others. The simple problem is that, for whatever reason, the factory firmware in this router does not pass on the domain search suffix through its inbuilt DHCP client. Without that, cdn doesn't resolve to anything, so you can't download the self-help tool and you're effectively stuck at a "can not find this page" screen. If you google at this point you can find many people who have hit this problem, and various information from erroneous suggestions that you've been hacked (?) to most people just giving up and moving into Comcast phone support hell. Assuming you now don't have internet access, you can complete the process with a quick swizzle. Somebody might be able to correct me on this, but I don't think you want to run the self-install tool from an actual computer plugged directly into the modem if you have a router in the picture, because the wrong MAC address will get registered. So, your best solution is to turn everything off, plug your computer directly into the modem, turn it on, get an address, download the tool, turn everything off, plug the router back-in to the modem and then run the self install tool. At this point, everything just worked fine for me. Netgear should probably fix this by correctly passing through the domain search suffixes in their routers. Comcast should probably fix this by doing some sort of geo-ip lookup to give clients a fully-qualified address in that webpage to download the tool even if their router is broken (or really, does downloading that file really require a content-delivery network?). You can probably fix this by running Openwrt on your router before you start. Otherwise, the Zoom modem and the Netgear WNDR3700 seem to make a very nice combination which I would reccommend.
