David Welton: More Github

Before I get started, I want to make it quite clear that I have no problems with Github - au contraire, they provide a very nice service. What my speculation centers around is the social dynamics of Github. One of the Github guys writes a nice response to my original post, here: http://ozmm.org/posts/linux_vs_classic_dev_style.html First of all, apologies for the comment bug. In theory, it has been fixed by the Typo guys, I just need to find the time to upgrade. Chris mentions that it's possible to create a "SourceForge style" project on Github. I see that it's possible to add collaborators, so I guess that's what he means. I still find it a bit ugly to have things at .../davidw/... but that's not very important if the URL is at least stable, rather than hopping around to whoever has the latest fork and updates of the code in question. In my other post, I talked about people being less interested in doing what it takes to contribute to existing projects, rather than forking them, unless it's really called for. Here's a concrete example of how things might go wrong. At my current consulting gig, we were looking at utilizing actionwebservice to do some SOAP stuff. That code is not part of Rails anymore, but that's not the problem - surely someone has decided to take up maintenance of the gem, right? Well, yes... but let's look:
root@fortrock:~# gem1.8 search -r actionwebservice
*** REMOTE GEMS ***
actionwebservice (1.2.6)
datanoise-actionwebservice (2.2.2)
dougbarth-actionwebservice (2.1.1)
nmeans-actionwebservice (2.1.1)
So we have the original, clearly out of date, and three others. Yuck... I guess we'll use the 2.2.2 one, but who knows if perhaps the others contain some good stuff too? Let's Google it. http://www.google.com/search?hl=en&q=actionwebservice The first link is to a RubyForge project, which is basically dead. A few links down, there is a link talking about a more recent version, at the Datanoise site. However, it's one of many. Confusing. If you go to the github page for the datanoise version of actionwebservice, the README has this:
The latest Action Web Service version can be downloaded from http://rubyforge.org/projects/actionservice
Hrm. We were just there and that doesn't seem quite right... Sure, it's an easy enough oversight to ignore, but it adds to the confusion. Now, this is not really a serious problem, but do you see how it could get worse over time, as various people fork the code, write blog entries, and so on? It would get harder for someone interested in utilizing the code in question to ascertain which is "the" version. It's not hard to imagine situations where two forks add different bits of useful code. Typically, in situations like this, new users, those who don't know the code at all, are also the people least able to look through all the diffs and changes and log entries and what not in an attempt to merge any changes that might be useful. This leads to a "paradox of choice" type of problem. Another consideration, this one more positive, is that perhaps people are putting code in Github that, in the past, might have simply remained on their own computers, with no effort whatsoever to share it, so in that sense, Github might be doing people a service by at least making the code public. However, even in that case, if the service fills up with code that people have simply "thrown over the wall", rather than creating a genuine open source project, with a community, communication channels, and so on, it could get a reputation for having code that you have to handle with care, as a lot of is just stuff slapped up there without much thought to quality or continuity. Anyway, the Github guys have done a nice job with the service, and I'm sure they'll continue to improve it. Who knows, perhaps they have some good ideas about mitigating some of these potential problems that they'll be rolling out soon.

MJ Ray: SPI January 2009

The monthly board meeting of SPI will take place on irc.oftc.net #spi tonight (Wed 21 Jan) at 20:00 UTC. Members may have seen that the meeting announcement is delayed because the secretary has been ill and it seems that none of the other board members has stepped in to take over. I think the only new associated project currently under discussion is waiting for a legal opinion, so your guess about the meeting contents is probably as good as mine. My guesses: there will probably be a treasurer s report; Martin Zobel-Helas has been filling in the gaps in the 2007-8 minutes, so there ll be two or three sets for approval; the secretary may report on website redevelopment progress; Privoxy might have taken up the offer of associated project status from the SPI December 2008 meeting; and there might be a report on Tux4Kids trademarks. Watch the comments below this article for a link to the summary when posted.

Robert McQueen: Quitclock

(Apologies in advance for the shameless plug.) It s possibly a little late to talk about new year s resolutions, but if anyone is a Facebook user and has given up smoking (or plans to), you might be interested in Quitclock. My brother Alastair is a health editor for the Bupa private health insurance company, and thought of this neat project which was implemented by my housemate Martin Kleppman, and announced at new year. It helps you keep track of how long since you ve smoked, how much money you ve saved, lets you and your friends know how you re doing, and has health tips about the improvements that you can expect from your new-found abstinence. I m not a smoker but hopefully someone will find it useful.

Biella Coleman: Pirate Philosophy

Culture Machine has just come out with a new issue and it is all on pirates. Looks like a great collection.

Biella Coleman: Google it

So I am still getting a lot of comments on my blog about BCBS horror stories and recently this one was submitted, which seems particularly horrific:
I had an accident in June. I was rushed to the emergency room on a Saturday afternoon. An Orthopaedic surgeon that was on call came in to set my bones. BCBS says that the physician was out of network and they paid $3900 of a $21,000 bill. I had NO choice and I was not in any shape to find out if the doctor was in-network. Seems illegal to me.
Wow. I also got an email from someone else also undergoing some horror who has asked me for the email of the public relations director who had emailed me many moons ago. Normally I would feel somewhat guilty giving it out, but given that BCBS is seriously causing a lot of problems for people all over the country, I think it is important that top executives in the company know they are causing havoc and financial problems for scores of peoplethis one is pretty horrible as well . Second, the information is already public and so one can easily find this person s name by googling BCBS Horizon public relations director (You will get his name) and then google his name and you will get his email and phone number. Good luck. If I were not a professor and were financially secure, I would definitely spend all my time on health insurance reform activism (and kick some serious ass, since I really enjoy that type of political work). In the meantime, I will help in the little ways I can and hope that this administration, which is a vast improvement over the last, will also rattle the health insurance industry as well. There are also groups out there doing great work, so if you are into reform, do lend them a helping hand if you can!

Steve Kemp: I saw green fields and flowers. I could smell the grass.

Fabio Tranchitella recently posted about his new filesystem which really reminded me of an outstanding problem I have. I do some email filtering, and that is setup in a nice distributed fashion. I have a web/db machine, and then I have a number of MX machines which process incoming mail rejecting spam and queuing good mail for delivery. I try not to talk about it very often, because that just smells of marketting. More users would be good, but I find explicit promotion & advertising distasteful. (It helps to genuinly consider users as users, and not customers even though money changes hands.) Anyway I handle mail for just over 150 domains (some domains will receive 40,000 emails a day others will receive 10 emails a week) and each of these domains has different settings, such as "is virus scanning enabled?" and "which are the valid localparts at this domain?", then there are whitelists, blacklists, all that good stuff. The user is encouraged to fiddle with their settings via the web/db/master machine - but ultimately any settings actually applied and used upon the MX boxes. This was initially achieved by having MySQL database slaves, but eventually I settled upon a simpler and more robust scheme: Using the filesystem. (Many reasons why, but perhaps the simplest justification is that this way things continue to work even if the master machine goes offline, or there are network routing issues. Each MX machine is essentially standalone and doesn't need to be always talking to the master host. This is good.) On the master each domain has settings beneath /srv. Changes are applied to the files there, and to make the settings live on the slave MX boxes I can merely rsync the contents over. Here is an anonymized example of a settings hierarchy.. So a user makes a change on the web machine. That updates /srv on the master machine immediately - and then every fifteen minutes, or so, the settigngs are pushed accross to the MX boxes where the incoming mail is actually processed. Now ideally I want the updates to be applied immediately. That means I should look at using sshfs or similar. But also as a matter of policy I want to keep things reliable. If the main box dies I don't want the machines to suddenly cease working. So that rules out remotely mounting via sshfs, nfs or similar. Thus far I've not really looked at the possabilities, but I'm leaning towards having each MX machine look for settings in two places: That way I can rsync to /backup on a fixed schedule, but expect that in everyday operation I'll get current/live settings from /srv via NFS, sshfs, or something similar. My job for the weekend is to look around and see what filesystems are available and look at testing them. Obmovie:Alive

Obey Arthur Liu: Debian Summer of Code 08 : Where are they now (part 1/3)

It s been a while now since the 2008 Summer of Code ended. This year, twelve (?) projects were selected. That s twelve students working full time on a Debian-related project during the summer. The Google Summer of Code has sometimes been criticized in the past for having a poor student-developer retention rate inside the host projects. One of the goals of the program has always been to bring new people to budding or established free software organizations and it s a pity that some would leave the project as soon as the program ends. On the other end, poor integration of created code within the project leads to work that is hard to merge in, or worse, doesn t get merged in at all. That s a waste of time and resources and a probably cause of global warming as well. Hopefully, it s not always the case. Some people choose to stay committed within the organization in the long-term. Useful code gets merged in and pushed to the public. I am going to give a talk about this at FOSDEM (go to FOSDEM!) so I m giving you a little preview. I need your help to collect information for my talk. As you know, information is always hard to come by with these kinds of projects so anything can be useful. Without further ado, let s have a look at the cast of the Debian Google Summer of Code 2008: Netconf, a network configuration management system Presentation Netconf is a network configuration management system designed with modern network infrastructures and the needs of roaming users in mind. It is a personal project of Martin Krafft that he started in 2007. He did some presentations about it that you can find on the dev website. The project proposal was introduced by the mentor. The work was mainly about completing the roadmap items for version 1.0. Most of the design was done and code fleshed out. The stated goal was to have netconf ready for lenny. Martin noted that due to lack of regular free time, he couldn t reach that goal by himself. Student Jonathan Roes was a computer science graduate student from the University of North Carolina at Charlotte. He had programming experience as a hobby for a long time and wrote some free games and libraries for the Nintendo DS and some proprietary webapps. He submitted a few little patches in mid-march right after the publication of accepted mentoring organizations and went on to work from mid-may to mid-august. He wrote a lot of code right into the trunk since the whole project was a prototype. Result The last commit by Jonathan was also the last to date in the main netconf git repository. No further progress has been made and obviously netconf didn t get into lenny. I couldn t find any further public involvement of Jonathan within Debian. The ultimate Debian database, all things Debian in a SQL database Presentation The Ultimate Debian database wants to reunite all Debian data sources in a SQL database The project was mentored by Lucas Nussbaum and co-mentored by Stefano Zacchiroli and Marc HE Brockschmidt. The project proposal was introduced by Lucas. Student Christian Neronus Von Essen is.. well, there wasn t much information readily available on him. Result The whole project is coded up and working well with a whole bunch of data sources. There will be a talk at FOSDEM about this so I ll leave it to Lucas to talk about it in detail. I couldn t find any further public involvement of Christian within Debian. Security-beta, a beta testing for Debian security updates Presentation The task is to improve the quality assurance process for security updates by providing a public security update beta test program in addition to the existing QA done for security updates. During the preparation of security updates, there s an inherent delay between the initial upload of the fixed packages and the time until the packages have been built on porter machines. This time gap will be used for a new security update beta program. The project was supposed to be mentored by Moritz M hlenhoff. Student The project was supposed to be done by Nico Nion Golde. He is studying computer sciences at the Technical University of Berlin. He s also a DD. Result There s no nothing. Nico, what happened ? And obviously, he s still developing for Debian. Debgraph, a generic infrastructure for the development of packages management tools Presentation In a large software ecosystem such as Debian Linux, there is the potential for dependencies among software packages to create complex management and technical problems. For example, dependency loops (cycles) in which a package directly or indirectly depends on itself can confuse package management tools as they determine the proper order of package installation. debgraph helps developers to solve this problem by enabling generic queries (e.g., Give me all the nodes that depend on package X ) against the graph of packages and thus automating much of the manual labor that is typically involved in resolving dependency problems. The project was mentored by Robert Lemmen, who introduced the project proposal. The project was already started and the C++ code foundation was done by the time it was proposed. Student The project was executed by Adam Jensen, research assistant in the Software Engineering and Network Systems Laboratory at Michigan State University. Result Adam maintained a blog about his progress and finished ahead of schedule. However, the resulting work seems to be unused, which is a pity since the code could be used within other programs (package managers?). I couldn t find any further public involvement of Adam within Debian.
That s all for now. The information is quite fragmented I admit. Most of it was pulled from Google, mailing lists, commit logs, blogs, whatever. If some projects are lacking in information here, it s because I couldn t find it readily (which is an issue in itself!). In my next post, I ll try to analyze the success and failures to extract some insight. Teaser: pet projects!
If you re a student or a mentor mentioned above, feel free to fill any of the blanks in my report. It s much appreciated. You re not a student or mentor mentioned above and have an opinion on how to improve the next Debian Summer of Code ? Feel free to comment.
Sledge, ping! Here s a list of projects to be described in my next posts:

Wouter Verhelst: Re: emulated buildds

Aurelien, your claim is wrong. About a year ago (IIRC; might've been longer), the Debian/m68k team decided that it wanted to do emulated buildd hosts, since that would allow us to more easily keep up with unstable. We discussed it in the team, we discussed it with ftp-masters, and we all decided to go for it. We've had emulated m68k builds go to the archive for quite a long time, with full knowledge and agreement of ftp-masters. We realized that emulated builds could be problematic, but we evaluated the issues and decided to take that risk, as a team. The reason your key was rejected for uploads of arm binaries was because you started doing those emulated builds without discussing it with the arm buildd maintainers, and without discussing it with the arm porters. You just decided it might help, so it must be good, right? Finding the difference is left as an exercise to the reader.

Gunnar Wolf: About the recent events and possible outcomes in Israel and Palestine

Several friends, from different groups and backgrounds and with different points of view regarding the current war in Israel (and regarding the Arab-Israeli conflict in general) have asked me for an explanation on what is happening there, what is (my view of) the real conflict, its causes... and any possible answers. And yet I am quite far from being an authority, I do want to write something about it. Be prepared, as this post is quite long.
And yet, after writing frankly a lot more than what I expected... It is by far not enough. I have still much more to add, but I have to say "stop" at some point. So, here you have it: My points of view, as well as some explanation on why are we standing where we currently are.
I am writing this based just on my personal experiencie and, of course, my personal point of view. Furthermore, I wrote a good part of this text while riding a bus, with no network access, so I am offering very few references - In any case, it will allow me to make much more progress. References always take as much time as the text itself! About me Why am I writing this? Why do people ask for my opinion? I must start by explaining who I am, so the rest of this makes sense. I am a Mexican Jew. That means, I was born in a Jewish (albeit secular) family, and grew up in an environment with general Jewish culture. My direct family (say, my parents and brother, and to a lesser degree my closest cousins) are not at all religious, I'd even venture to say most of us are complete atheists. Yet, besides the cultural belonging (which is a mixture of a Eastern European culture with lots of Idish words and dishes and general humor), my family has a strong national identification - In other words, I grew up in a fully Zionist environment, which traces back to Poland.
My grandmother was member of Hashomer Hatzair in Poland, since the early years of its existence, late 1910s and early 1920s. What is it? To make it short, a Zionist Socialist, Kibbutzian youth movement. It has many similarities (and somewhat stems indirectly from) the Scouts many of you will be familiar with, but -obviously- has a way lengthier agenda. And, yes, nowadays I feel it is somewhat out of reach with the current state of the world - It was founded in 1913, and only slightly adjusted its principles since then.
I will talk more about Hashomer later on.
My grandmother arrived in the late 1920s to Mexico, for familiar and economic reasons, but still dreamt about living in Israel for a long time. As they grew up, first my uncle joined Hashomer in Mexico in the late 1940s, when it still pursued a very much Soviet-style ideals for Israel (one of the core points that changed during the 1950s); both my father and my mother joined in the late 1950s (in fact, that's where they met). My cousins and myself were very active in the 1980s and 1990s.
The Iszaevich family has something very unusual, I'd say, engraved in our genes. We live very deeply our ideologies. That's the only explanation I can find to the way we all have led our lives. I won't go into the other family members' details, but just into mine: I was fully convinced of all we taught to our younger members and what we discussed among ourselves. I am among the very few people who really learnt Hebrew at my school, and that was only because I really cared - I know some people that just after 12 years of pseudo-learning could maybe utter a few phrases.
After finishing high school I went with my Hashomer group, together with people my age from other similar-minded Mexican Zionist youth groups, to live and learn for a year in Israel, on what is usually known as shnat hajshar - A year to get ready. To get ready to what? But of course, to come and give back go the younger groups of the movement, and finally go back to Israel and settle there definitively. I came back to Mexico, and after one year I did the only thing that was logical: I became an Israeli and went to live to a kibutz - Zikim, a beautiful place just between Ashkelon and Gaza, very near the sea shore. It was a beautiful period in my life, and I really enjoyed it - But it didn't last for very long - I quickly grew to hate the Israeli society at large. A society full of rage, of hatred. Not just between Arabs and Israelis, as many would think from the outside, but between religious and seculars. And between immigrants and locals. And between leftists and rightists (in several dimensions, as it is one of the countries where you can most easily be a economic leftist while being a political rightist - a complex society it is). A society full of disrespect and intolerance. A very hypocritical society. And one of the things that most shocked me: I wanted to live in a society of proud of its existence, that's what I had learnt Israel was - But Israelis aspire and dream of being anything else (and mostly US-Americans) in a way that made me sick, more than anything I had previously seen in Mexico.
I loved the life at the Kibutz, and I loved being an agricultor, doing hard work every day and literally getting the fruit of it. However, I cannot live isolated to a 300-people universe - At least once a week you have to go to the city if you don't want to become insane. And I could not stand the sick Israeli society.
Anyway, to make things short: After six months as an Israeli, I came back to Mexico. I went through a long period of finding myself, as I could not uphold anymore my Hashomer ideology (if I am not going to live by it, how can I continue teaching it?). Many people do anyway, but for the first months, where my Hashomer work was basically all of my life, I felt really uncomfortable. So, in short, I severed all of my relations to the Jewish community, and even denied for a long time my Jewishness until I found a (I think) better balance.
Today I am at peace. But anyway, I wanted to talk about myself in the critical period that marked me in this regard: The 1990s. Enough, lets get down to business. Zionism 1870-1920 Many people argue that the Jews invaded the Palestinians homeland - And yes, nowadays I cannot counter this. But we cannot judge what happened then based on what we see now.
Modern Zionism started around the 1870s. The Jewish history is full of pogroms and persecution, in different countries all over Europe - And a group of young people decided the only solution was to build a place to call their own. And yes, this was full of idealism and in no small part the foolishness of youth. For several centuries and up to 1920, all of current Middle East were provinces of the Ottoman Empire. Before Zionism began, the population of today-Israel was very sparse, not more than 400,000 people - up to 5% of them Jewish, around 10% Christian Arabs, and the remainder, Muslim Arabs. Of course, the low population was mostly because the country was mostly hostile - A desert in the South, mostly swamps in the North, and some minor towns mostly in the hills. It was a mostly forgotten province, away from the central Turkish rule, and there had been no frictions with the local population. It was a nice place to go, thinking -again- as a fool youngster, or as an idealist. They said, lets take a folk without a land to a land without a folk.
The number of accomplishing Zionists (this is, people who actually went to Israel instead of just talking about doing so) was not high during the first decades. But towards the 1890s, it gained critical mass. The political Zionist movement was born, with Theodor Herzl as a leader, and they started pushing -politically- for different governments to concede a territory to Jews. They went to the Turks, and didn't really get much echo. Went to other colonial powers of the time, and got unfeasible promises with no real backing (i.e. Birobidjan in Eastern Russia, Uganda in Africa)... And, as it happens in strongly ideologized movements, the movement started splitting into different groups with slightly different positions.
And no, I am not talking about the People Front for the Liberation of Judea and the People Judean Liberation Front, but I very well could. Sometimes the differences are as ridiculous as that. But hey, I take that most of my readers are acquinted with the Free Software issues, right? Think BSD vs. GPL vs. OpenSource. To give a broad idea - Only in Mexico City, with a very small Jewish community (~30,000 people), in the mid-1990s we had over 10 such movements, with 50-150 youngsters attending each. And even though some were local, and even though some very important ideologies are not represented in this country, they are all different enough to exist as separate entities. British Mandate The Ottoman empire was divided after the first World War. Its possesions in Europe became independent states, while in Asia (and Africa, if you take the semi-independent Egypt and part of Sudan into account) they were taken over as colonies or protectorates by France and the UK - Evidently, attempting to secure a long-term dominion over the area. In some aspects, they failed. In some aspects, they were (and still are) tremendously successful. The division of people by setting arbitrary boundaries has led to countries sustainable only by force and a harsh rule (such as Iraq, Lebanon and Syria), or doomed to poverty (and thus submission) due to lack of natural resources (as Jordan). Focusing on Israel/Palestine, the UK entered the area by making mutually incompatible promises to arabs and Jews - i.e. the Hussein-McMahon letters and the Balfour declaration, both ambiguous enough to lead to... Well, today. The UK rule was disastrous to the region, both in giving (and taking away) power from all sorts of puppet regimes, and swiftly going away as soon as things started looking too complicated. Yes, typical colonialism.
So, while up to the 1920s there was no real animosity between Arabs and Jews (as i.e. the Faisal-Weizmann agreement shows), during the next decades the seeds of hatred started growing, from both sides.
Many people still quote the 1947 partition plan as the direct antecedent towards Israel's real existence - That was not the first partition plan that existed. Ten years earlier, the Peel commision suggested a similar partition involving forceful population transfer. And many people see the separation of Transjordan (now Jordan) from Palestine in 1922 as a first partition. It is understandable that both partition plans (much more the 1947 than the 1937 one) were accepted by Zionists: Going from having nothing to having something (and against all odds in the environment they lived) is acceptable.
From the Zionist side, two main groups rejected the partitions: The right-wing and religious groups, insisting that the whole of the Mandate should become Israel, and the left-wing groups, which advocated for a single, bi-national state, with equal rights for all of its population. Go over and read this last link, as it was quite interesting (to me at least) to see how this solution has kept existing and regarded by (relatively) many people, and has many interesting links. 1948 onwards: Where did the refugees come from? The November 1947 partition didn't exactly translate to a planned, smooth Israeli independence - It led to six months of revolts (basically, a civil war). By mid May, the UK government and troops abandoned the territory, and one day later, Israel declared its independence. And, of course, all neighbouring countries (and Iraq) sent their troops to invade Israel. The war lasted for over six months (cease-fire was signed in January 1949). There was an intense Arab campaign indicating the armies would enter Israel and devastate it, leaving no stone in place, indicating Arab population to temporarily leave the Jewish-destined areas. The war, they said, would not take more than a couple of months, and they would be able to go back home.
Only that... When the war ended, the results were far from what the Arab governments expected. Not only Israel continued to exist, but it conquered important territories.
Of course, the Israelis were not innocent from said exodus: During the 1947-1948 civil war, and the independence war, some of the existing so-called self-defense forces (some of them were really defensive, while some were quite aggressive, even terrorist) attacked Arab villages in strategic or predominantly Jewish areas to prompt them to leave - yes, what we today call ethnic cleansing.
I had (in my head) the number of 650,000 Arabs (from a total of slightly over a million) fleeing to neighbouring countries. Wikipedia states that it is somewhere between 367,000 and 950,000. A similar number of Jews were expelled from Arab countries, many of which arrived to settle at Israel (and many others went elsewhere - For instance, a good part of the Mexican Jewish community is from Syrian origins - Many of them fleed in those years). Israel didn't accept back the (relatively few) Arabs that requested to resettle, as they were seen as hostile population - but neither did the countries that "temporarily" accepted the Palestinians accepted them as citizens. The Palestinian refugee camps today, mainly in in Lebanon, Syria, and the occupied territories held by Israel have terrible living conditions, and its population -despite living there for over 60 years- have no civil rights at all. Note that I'm omitting Jordan here, although it has several camps as well, as their situation is way better.
The Arab population that didn't leave did receive full Israeli citizenship. No, their living standards are not up to level with the average Israeli. The country and the society do have a sensible degree of racism and segregation. But the situation is nowhere as terrible as it is in the camps.
The areas which were originally to become Palestinian and were not conquered by Israel -this is, current-day West Bank and Gaza- bacame respectively Jordan and Egyptian territory. While Jordan did fully extend its soverignty covering the West Bank, Egypt didn't - Gaza is, since 1949, occupied military territory. Gaza, among the most densely populated areas in the world, has had their inhabitants under military rule ever since. When Israel returned the Sinai after signing the peace treaty with President Sadat, Egypt didn't accept Gaza back - And that's where today's greatest problem is born.
Now, Israel conquered those territories in 1967, along with the very sparsely populated Sinai and Golan. For the first ten years, the territories were basically only administered (yes, under a military rule). In 1977, with the first right-wing Israeli government, an extensive settlement policy began (and led partly to today's seemingly unsolvable situation). In 1980-1982, Israel withdrew from the Sinai. In 1981, Israel claimed full soverignty over the whole of Jerusalem and the Golan. In 1993, the "Oslo Agreement" was signed between Israel and the PLO, and it seemed we were heading towards a bright future. I lived in Israel between 1994 and 1996 - Yes, the most hope-filled period in the country's life.
Since 1996, I have tried to keep up to date with the country's evolution. All in all, even if I won't live there again, it is a country I learnt to love, a society I have long studied (even if in the end I did include many references, I wrote most of this text just off the top of my head, with the data I remember - so it might have several big errata). And yes, I keep the political stand I had 12 years ago: The only solution is to dialogue, to treat the current enemies -and not only their governments- with respect, recognizing their dignity and right to life, to self-determination. Only then we will change the status quo. How not to fight hatred Since 1993, the dream of peaceful coexistence seems to have faded. What we saw during the past three weeks, along to what we saw in Lebanon in 2006, is plainly a gross mistake if the goal is to achieve good, lasting peace.
Try to imagine how could life in Gaza be, even in the total absence of Israeli attacks. Just to set some numbers first: The Gaza strip hosts almost 1.5 million people on 360 km . When I lived in Israel, I was constantly surprised at how small a country it is - Israel tops at 550Km North to South, 150Km east to West (it is amazing, almost wherever you stand, except in the middle of the Negev, you can see the country's borders. Yes, I recognize as the border the so-called Green Line); over half of the territory is a desert, and it hosts seven million inhabitants. And it is hard to imagine how that country can be economically viable.
I do not find it feasible to imagine Gaza and the West Bank integrating a single country, and not only because they are separated by ~40Km, but because they are so sociologically different. People in the West Bank, yes, live opressed under military rule and subject to a much more constant, more visible apartheid-like state (as the territory is truly sprinkled with Jewish outposts which many Israelis refuse to recognize as their own, but still, which have incredibly higher living standards). The best land has been taken away from them, yes, but they have some space between cities to have some farming, to communicate, to... Breathe. Besides, West Bank inhabitants -even those in refugee camps- have much better living standards than anybody in Gaza. It is still an overpopulated area, but not nearly as much as Gaza.
Gazan population have been driven towards extremism. And yes, there was a civil war between Palestinian factions, as the world views between both populations are completely different - However hostile a Jenin inhabitant can be towards Israel, he does not lead the life -if it can so be called- you see at Khan Yunis.
But back to Gaza... What Israel is doing (and not only during this military operation terror campaign is wrong, from any rational point of view. Israel wants Hamas to become weaker? Then don't drive the population into supporting them!
Palestinians started giving over 50% of their support to Fatah (ex-PLO), and under 20% to Hamas. That was less than 15 years ago. However, Fatah has shown to be corrupt and inefficient at building infrastructure and improving life conditions, ineffective at negotiating a permanent agreement which secures dignity and sustainability to their people. Hamas stands as a religious, righteous organization. There are no serious corruption charges against any Hamas leaders. Hamas is clearly still at war - They didn't subscribe any peace agreement so far, and their stated #1 goal is to build a Muslim State in the whole of Israel. And the Hamas movement -like Hizbollah in Lebanon- has built quite a bit of infrastructure in the areas they control - Mainly housing. Yes, housing where they mix their own offices, many will accuse, getting human shields for free. But still, they are benefactors to a dehumanized, pauperized population.
I find it obvious that, if living conditions were at a basic level in the region, support of Hamas would decrease. Even more, of course, if they improved due to Israeli support. Israel controls this territory, so it is responsible for the well-being of its population, like it or not. And Gaza is simply too small and low on resources to survive by itself.
I was a bit surprised to find mention -although very brief- of a three state solution - And yes, this is close to what I would expect as a viable outcome. It is clear that Israel will not ever grant full citizenship to the Palestinians, as they would -euphemistically speaking- challenge the Jewish character of the State. Dropping the euphemism, Israel relies on apartheid in order not to become an Arab majority country. I might have some numbers wrong, but AFAIK, there are ~7 million Israelis, 20% of which are Arab citizens (which means, 1.4 million Arabs and probably 5 million Jews, with many other minor denominations for the difference), and ~4 million Palestinians live in the territories. Today, the country is already predominantly Arab, or at least is close to being so. So, Israel should permanently, formally disengage from all of the occupied territories. And in order to ensure violence stops, start a comprehensive, unconditional, long-term aid program. Start with giving them autonomy to regain their sea, as the Gaza port has long been closed. Allow the airport to operate again. Instead of bombing tunnels in the Egypt-Gaza borders, allow Gaza to trade with Egypt - Perhaps even to integrate territorialy, if the conditions are met. Treat their people with respect, and help them ease the terrible situation they have lived for so many decades - and then, undoubtely, terror will stop.
The West Bank? Possibly it could become a Palestinian state by itself. Possibly, it could integrate back to Jordan. That would be up to Jordans and Palestinians to decide. Of course, Jordan has already a large segment of its population defining itself as Palestinians, which counts both for and against. So, I won't venture into this supposition.
But anyway - Back to what prompted me to write this text -yes, a very or maybe even too long text - I hope somebody even takes the time to read it!- is to explain what is my point of view on the current situation, and why.
Today, a cease-fire was announced, after 23 days of murder and destruction. I sadly do not hold very high hopes for it to be lasting, much the less to be enough, to lead to what they call a de-escalation of the conflict. The most I can currently do is to voice my opinion, and hope that mine is just one more voice pointing to a sane solution, to a permanent, dignifying way out, for all people involved. Every people has the right for survival and for safety. We cannot deny this to any others. And certainly, we cannot expect anybody not to fight for their right to live.

Axel Beckert: Traveling plans for the first half of 2009

Since the time between the years is traditionally family time for me, I never were at the Chaos Communication Congress. So I wasn t at 25C3 either. All the more I look forward to HAR2009 this summer (13th to 16th of August near Vierhouten in the Netherlands), but also because, for the last three years I always have been in the Netherlands for one week in summer, sailing with friends on the sselmeer. But before HAR2009, there will be a bunch of other events to visit and people to meet in real life: Then there will be the big summer holidays driving around in the middle of Europe with the 2CV and taking part in most likely: This also means that I ll probably miss: at least unless one of the other events I plan to visit doesn t take place as expected or my plans change heavily. P.S.: Anyone thinks this amount of events justifies a Dopplr account? ;-) Or is there somewhere a free online service similar to Dopplr, but runs software under the GNU Affero General Public License like e.g. identi.ca and many other Laconica instances do for microblogging?

Axel Beckert: How I use my virtual desktops

Many months ago I stumbled upon this German written meme about how users use their virtual desktops. I use virtual desktops since my very early Unix times (tvtwm on Sun Sparc SLC/ELC/IPX with greyscale screens running SunOS 4.x), so in the meanwhile I use them nearly everywhere the same way. Short Summary 3x5, no overlapping windows, either tiling or fullscreen, keyboard navigation, xterms, yeahconsole, FVWM, panel for systray. Window Manager of Choice My window manager of choice is FVWM since more than a decade. I tried others like Sawfish, Metacity and Compiz, but I couldn t get them behave like the FVWM I got used to, so I always came back. Since I hate overlapping windows, I use FVWM a lot like a tiling window manager. FVWM has this nice function to maximize windows so that they occupy as much space as available, but do not overlap other windows. This function was also often missing when I tried other window managers. I though do not want to use real tiling window managers since I have a few sticky windows around (e.g. the panner with the virtual desktops and xosview) and they shouldn t be overlapped either. Virtual Desktops Switching between virtual desktops is done with the keyboard only with Ctrl-Shift as modifier and the cursor keys. The cursor keys are usually pressed with thumb, ring and small finger of the right hand. Which hand presses Ctrl and Shift depend on the situation and keyboard layout, but it s usually either ring and small finger of the left hand, or pointer and middle finger of the right hand. So I m able to switch the virtual desktop with only one hand. I have always three rows of virtual desktops and usually four or five columns. The top row is usually occupied with xterms. It s my work space. The top left workspace usually contains at least one xterms with a shell and one with mutt, my favourite e-mail client since nearly a decade. At home the second left virtual desktop in the top row usually contains a full-screen Liferea (my preferred feed reader) while at work it contains the GNU Emacs main window besides two xterms. Emacs and the emacs server are automatically started at login. This also means that I switch the virtual desktops when I switch between mutt and Emacs for typing the content of an e-mail. Did this already during my studies. (At home mutt runs inside a screen, so there I just switch the virtual terminal with Ctrl-A Ctrl-A instead of the virtual desktop. Not that big difference ;-) The other virtual desktops of the the top row get filled with xterms as needed. Usually one virtual desktop per task. The middle row is for web browsers. One full screen browser (usually Conkeror or Opera) per virtual desktop, often opened with many tabs (tabs in Opera, buffers in Conkeror) related to the task I m accomplishing in the xterms in the virtual deskop directly above. The third row usually contains root shells for maintenance tasks, either permanently open ones on machines I need an administrate often (e.g. daily updates of Debian testing or Debian unstable machines), or for temporary mass administration (Linux workstations on the job, all Xen DomUs of one Xen server, etc.) using pconsole. yeahconsole Additionally I have a sticky yeahconsole running, an xterm which slides down from the top like the console in Quake. (It s the only overlapping thing I use. :-) My yeahconsole can be activated on every virtual desktop by pressing Ctrl-Alt-Z (with QWERTY layout, Ctrl-Alt-Y with QWERTZ layout). It s the terminal for those one-line jobs then and when, e.g. calling ccal, translate, wget or clive. Changes over time Of course the desktop usage changes from time to time: At work I have more than one monitor, so in the meanwhile the second row with the web browsers moved to the second screen with independent virtual desktops (multiple X servers, no Xinerama). The second row on the main screen at work is now used the same way as the third row with a slight preference for the permanently open shells while the third row is more used for mass administration with pconsole. At home I used XMMS respective Audacious for a long time (my FVWM panner and xosview are exactly as wide as WinAmp2/XMMS/Audacious, guess why:-) which usually was sticky the same way as the panner and xosview are. But when I started using last.fm recently, I moved to Rhythmbox (after testing some other music players like e.g. Amarok) which I use in fullscreen as I do with web browsers and the feed reader. So it occupies a complete virtual desktop, usually the second one in the middle row below the feed reader because I don t need a corresponding web browser for the feed reader. (Just found out that there is a last.fm player for text-mode, so maybe that will change again. :-) Another thing which changed my virtual desktop usage was the switch from a classical tabbed web browser (Galeon, Kazehakase, Opera) to the buffer oriented Conkeror. With a tabbed web browser I have either no overview over all open tabs (one row tab bar or truncated tab menu) or they occupy too much space of the browser window. That was another reason for more than one browser window and therefore more than one virtual desktop with fullscreen web browser windows. With Conkeror tabs are optional (and not even enabled by default), Conkeror uses buffer like Emacs and if you want to switch to another buffer, you press C-x b and then start typing parts of the buffer s name (e.g. parts of the URL or the web page title) to narrow down the list of buffers until only one is left or until you have spotted the wanted buffer in the list and choose it with the cursor keys. So the need for more than one browser window is gone. For a long time I didn t need any task/menu/start/whatever bar on my desktop. But since neither NetworkManager nor wicd have a comand-line interface (yet) and bluetooth seems also easier handled from the system tray my laptops also use either gnome-panel (big screen, long sessions with FVWM) or lxpanel (formerly used trayer; use it on small screen, short sessions with ratpoison or matchbox) on my laptops. It s sticky and always visible. (No overlapping, remember? ;-) The panel is usually at the bottom on the screen as by default with Windows or KDE, not at top as with GNOME and MacOS. Only on the OpenMoko, I have the panel at the top to be close to what I m used from Nokia mobile phones. Things I tried but didn t survive in my setup: Systems without Virtual Desktops Anyway, there are systems where I don t use virtual desktops at all. On systems with a screen resolution so small that there s not enough space for two non-overlapping, fixed font 80x25 xterms on the screen (e.g. on my MicroClient with 8 touch screen, the 7 EeePC or the OpenMoko) I do not use virtual desktops at all. On such systems I use all applications in fullscreen, so switching between applications is like switching virtual desktops anyway. My window managers of choice for such systems are ratpoison for systems with keyboard and matchbox for system without keyboard. With ratpoison you treat windows like terminals in GNU screen, so there are no new keybindings to learn if you re already used to screen (which I use nearly daily since more than a decade).

René Mayorga: yay!, I m a Debian Developer \o/

following the traditional post.
I got an email today, telling me that I m a full Debian Developer now, I started my NM process on 2007-12-10 it took a bit more then a year, and now I m the first DD of El Salvador I have to thanks to all people that help me out, anibal, gregoa, dmn, mlt(Marcela), xerakko, twerner, benh and some more people that I don t remember.

Biella Coleman: Easy to Miss



calle-monjas, originally uploaded by the biella.
In the last 8 years, I have spent a lot of time in Puerto Rico and I always hit the Old City for some food, walking, music, and beautiful views. When walking around my favorite streets, I noticed for the first time the lovely tiling pictured above, which features 5 dancing nuns. Even though I have walked on this street probably hundreds of times, I have never noticed it until last trip. While this is a very small detail there are many things one might overlook when visiting PR as they are not well known. One of the easiest things to miss is my favorite trail in the National rain forest, El Yunque, Tradewinds. It is easy to miss because it is not on the main road (It is on the closed service road, which you reach at the end of 191) and it is not mentioned very often in travel books and web pages. But if you are visiting El Yunque, I recommend the trail. It is as lovely as can be. Since it is not frequented very often, I would make sure to have a hiking buddy as it is easy to slip and fall (there is tons of mud). But do check it out if you visit the rain forest. It is really lovely.

Biella Coleman: Blue Cross No Shield

After two years of phone calls, nasty emails, filing claims and reports, Blue Cross Blue Shield of NJ finally ponied up every last cent of cash they originally did not want to pay. Since the ordeal began, many BCBS customers left comments here where I chronicled my plight and many have also sent me emails as well. In the end, I think I was successful mostly because I had the email of the director of public relations (he made the mistake of emailing me) because well, I would send him these emails and I think he just did not want to receive anymore. Recently I received an email from Reynold Weidenaar with a pointer to his webpage where he is also chronicling what is happening with BCBS since they want to deny coverage for physical therapy. This is great and more folks need to do this exact thing, which is chronicle every last detail in a public place. In the end, they have a lot of paperwork and we need to turn it back to them and in very large numbers.

Wouter Verhelst: Filesystems: the saga continues

Bernhard comes up with a few arguments in support of multiple filesystems which, in my arrogant opinion, make no sense. The first argument (about hardlinking a file to your homedirectory until something bad is discovered in one of the binaries) has been sufficiently debunked by Joey Hess. The second and third arguments are the same, really. Repeating your argument won't buy you any beer, sorry. Finally, all your arguments talk about server. I was talking about laptop. I don't know about you, but me, I'm not in the habit of loaning out my laptop to someone I don't trust. I'm not even in the habit of loaning out my laptop to someone I do trust, come to think of it. I do run some servers on my laptop, but I also have a firewall on my laptop that refuses incoming connections. This is a laptop. Not a machine in a data center. As such, the only person with access to my machine is me. Now I don't say I trust each and every bit of software that I run on my laptop, but I do trust myself. I won't start scanning my laptop's hard disk for rogue SetUID hardlinks in another user's home directory, because there isn't another user, stupid! Paranoid security is nice and dandy and totally useless. Security is all about trade-offs. Even Bruce says so: if the cost of a security measure (having to deal with with 73 filesystems) does not outweigh its benefit (protection against cosmic rays changing not only my firewall configuration, but also writing a suid CGI binary and installing that in /usr/lib/cgi-bin), then it's just not worth it. Now of course you might argue that 'having to deal with 73 filesystems' is no cost at all, in which case it would be worth it. But to me, it certainly is a cost, and one I'm not willing to take even if it did protect me against a real-life problem. And if someone were to break into my system, I'll just reformat it and recover from back-ups. I won't even have to revoke my GPG key, this time, since it's no longer on the disk.

Andrew Pollock: [tech] USB power switch, part 2

Continuing with my mission to control the power to some dumb USB-powered lights... Dann Frazier confirmed my theory that a USB hub would indeed do the job. I'd already found the hub-ctrl.c program he mentioned, but couldn't get it to work with my built-in USB ports of my laptop. It seems it all depends on whether the hub will support per-port power switching or not. (lsusb -v will tell you). So off to the mighty institution that is Fry's Electronics I went. The first two attempts failed, as did a borrowed hub. It seems most (at least the cheap one) use a Genesys Logic chipset, which does not support per-port power control. Fortunately I chose products that weren't in blister packs, so I was able to return them to Fry's in as-new condition and try again. Now that I knew USB hubs would do the trick, I did some more targeted searching, and found this thread where someone had been messing around with hubs to do what sounded like what I wanted. (Incidentally, this email in the thread also provided a nice looking Python program. I'm going to look at refitting it to use the "real" Python USB module.) I emailed the poster to ask him what brand of hub he was using. The answer was the Linksys 4-port hub So I managed to track down one of them last night. Yes, it works, but the downside is the hub itself requires external power, which is a bit unfortunate. Not only do I need to use a hub to make these lights software controllable, I have to plug the hub into a power outlet. Bleh.

Joey Hess: little known fact

An apparently little known fact about dpkg is that it clears suid bits when upgrading packages. This defeats the hardlink-a-suid-binary-and-wait-for-exploit attack that used to be a worry, and which apparently still is to some.

PPS, If you find yourself making statements like "While noexec is only a weak defense, it gives a little bit more protection", you are probably not really talking about security, but instead about a warm fuzzy feeling. PPS, If shellcode can create a suid root executable, it can create it in /root or some other directory that is not mounted nosuid.

Bernhard R. Link: Multiple filesystems for the paranoid

Given the current discussion on planet.debian.org about having only one or multiple file-systems, I just wanted to add a plea for having multiple filesystems. In my (perhaps a bit overly paranoid) eyes, having multiple filesystems is mainly a security measure. I prefer having enough partitions so that the following properties hold: Admittedly, those arguments may not be as convincing for a laptop as for a server. But I personally like to have paranoia enacted everywhere. Uniformness makes live much easier sometimes. Update: If having paranoid in the title was not enough to hint you that I do not claim a system losing a significant amount of security compared to more important measures, let it be told to you know. It's all about thinking about even the little things and taking measures where they do not otherwise harm. To get the warm fuzzy fealing I got when e.g. CVE-2006-3626 was found and my computers had nosuid for /proc already set. ;->
