Pablo Lorenzzoni: I feel so old

I don t know maybe it s because my birthday is coming (Feb 10th)... or maybe because my wife s birthday is around the corner (Jan 26th), but I am feeling too old these days. I know, though, that at least part of it is due to Web 2.0! I feel like being the last geek still using my own mail server (everybody else is using Google Apps) and a console-based MUA (I am using Mutt for as long as I remember everybody else seems to be on Google s Gmail). I still don t have a Twitter or an Identi.ca account. I still use my ICQ account! I never got an OpenID. Just yesterday I was lost in a conversation about Google Reader! I am a lost case Is this how it is to become an old days geek? Now I know what those bearded geeks from the 70s felt

Adrian von Bidder: The Most Important Announcement of 2008

... and I completely missed it. I've been ranting on and off about the Linux desktop world needing a shakeup, about non-techies shaking their head and not understanding why a Linux Desktop needs further clarification so that anybody knows what it means. Seems I'm absolutely not the only one: KDE's aKademy conference and GNOME's GUADEC are to be held side by side as the Gran Canaria Desktop Summit 2009 in early July this year. I finally saw this in connection with LWN's coverage (subscriber only at this time, sorry) of the recent Qt relicensing by Nokia. The true Year of the Linux Desktop finally? I doubt it, seeing that many people with little computer skills are still completely unaware of what's happening. And currently, I share the pessimism about OpenOffice.org's future as shown in Michael Meeks' interpretation of the commit stats. A real killer in the collaboration platform space is still missing, as well: there are numerous commercial players, quite a few commercial pseudo-opensource packages, tons of real opensource frameworks, but none that can be recommended, in my opinion, without its share of doubts, either about the features, the licensing, or the future. Still, it's been the year of the Linux desktop for me since about 1997 (and that means Debian since not long after that), and I do see the situation improving year for year, so here's a big thank you to all working on it.

Joey Hess: git as an alternative to unison

I've used unison for a long while for keeping things like my music in sync between machines. But it's never felt entirely safe, or right. (Or fast!) Using a VCS would be better, but would consume a lot more space. Well, space still matters on laptops, with their smallish SSDs, but I have terabytes of disk on my file servers, so VCS space overhead there is no longer of much concern for files smaller than videos. So, here's a way I've been experimenting with to get rid of unison in this situation.
    git clone --shared /mnt/fileserver/stuff.git stuff
Caveats: (Thanks to Ted T'so for the hint about using --shared, which makes this work significantly better, and simpler.)

Miriam Ruiz: In support of Patio Maravillas

Patio Maravillas is a self-managed government-independent social center in Madrid, placed in a squatted building that long ago belonged to school. The place currently belongs to a Real Estate company, Grupo 2 Reunidos. According to the law, the place has to be used for providing services to the community, which hasn t happened for 10 years. Nobody knows what plans they do have for the building, but there are suspicions that it might be related to property speculation. Nothing new on the horizon. The police are throwing them out of the building tomorrow morning, incidentally coinciding with the opening of the Foro Social Mundial (World Social Forum), for which Patio Maravillas was going to be one of the hosting buildings. Madrid isn t really known for supporting social movements in general, and has a conservative government, so feel free to think that the coincidence is not random. Patio Maravillas has been giving courses and workshops to the community since July 2007, and is very well considered and supported by different organizations. Supposedly whatever happens tomorrow will be without violence, but knowing how the Spanish Police behaves in this situations that is not very likely. The event will be streamed and probably recorded, and information will be twittered, so hopefully nothing serious will happen. I really hope the best for them. I d love to be able to be there with them, but as it is really not possible for me, I m giving them all my support from here. Good luck! Keep up the good work!

Martin-Éric Racine: Uninformed shoppers blaming Ubuntu: a brief TODO list for Canonical

My own perception of the debacle about the end-user who decided to cancel her college enrollment because she could not get Microsoft products to install on Ubuntu is three folds: Personally, I think that Canonical needs to hire an individual that understands the above three aspects and, most of all, how to remedy them, as its next OEM channel Manager, if they truly want to increase Ubuntu's market penetration.

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

Russell Coker: Security Lessons from a Ferry

On Saturday I traveled from Victoria to Tasmania via the ferry (to attend LCA), they grossly failed in their security measures and provide three lessons for others:

  1. Make it possible for people to read security relevant documents .

  2. Make obeying the rules not be a cost and make the fact known.

  3. Don t be lazy.

Here is the detail:

  1. When driving towards the ferry in a queue that lasted about 30 minutes just around the last corner there was a sign notifying me of the security rules. As soon as it was visible I started reading it but the security guard started frantically waving at me, the time taken to read it was holding up the queue. Therefore I never discovered the full list of things that I m not supposed to do.

  2. One rule was that cylinders of gas (such as propane) were apparently banned and should be surrendered - presumably to prevent a gas leak in the confined space of the ship s hold from risking an explosion. Anyone who did have such a gas cylinder would probably not want to have it stolen by the security people and would be inclined to lie and hope that the security people wouldn t find it. If they had made it well known that such gas cylinders would be stored in safe keeping for the duration of the voyage and then returned then they would have been more successful.

  3. They wanted to check the luggage compartments of all vehicles. To check the tail-gate of the Kia Carnival van I was driving first required that all the bags which had been put over the back seat be removed (they were resting against the tail-gate and would fall out if it was opened). When the guard realised that they would have to wait for me to empty a lot of luggage out they decided to just trust me that I didn t have any bad things on board (even though due to point #1 I didn t know what bad things were). This problem happened a second time when I reached Tasmania and the guards wanted to search for fruit.

Stefano Zacchiroli: ocaml batteries included debian packages

preview of OCaml batteries included Debian packages OCaml batteries included is a wonderful community-driven initiative to standardize the OCaml development platform. It is similar to initiatives sharing the same motto, like Haskell batteries included and Python batteries included (which then has become the legacy Python distribution), but I have always felt that OCaml was more desperately needing a similar initiative. David Teller and the OCaml batteries included team have been the first actually doing something to address the frustration of many otherwise enthusiastic OCaml developers. A couple of days ago, their efforts have given birth to a first milestone: the release of the first alpha version of batteries included. To help out, I've released as quickly as possible the Debian packages of OCaml batteries included. You can find them in experimental (actually in NEW, at the time of writing), and from my people.d.o space. I've only built the packages for amd64, if you need some other architecture you can build on it by yourself, but I recommend not trying to rebuild the -doc package (which takes 10 minutes on my laptop to build). You can reuse the -doc package I've built, which is arch: all, to rebuild only the -dev part unpack the source package and do fakeroot debian/rules binary-arch.

Stefano Zacchiroli: worst quoting practice

On the saga of weird SPAM, today I received a SPAM message in French about advertising a backgammon portal (WTF?). One of the funniest part was the end of the message (original, horrible line breaking preserved):
P.S.: Pour un meilleur suivi des communications, merci de bien vouloir laisser
l'int gralit 
du message et de r pondre au-dessus de l'historique.

Which roughly translates to: "to better follow further communications, please keep the totality of the original message and write your response on top of it". To be read as: "just in case you know how to quote properly, please don't do that".

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).

Axel Beckert: Mini-ITX based Home Server: Hardware Review

Mostly for my backups needs, I planned a Mini-ITX based home server around the Chenbro ES34069 Mini-ITX case which features four hot-swap S-ATA bays. I wanted a low-consumption motherboard and CPU in there (not only because of the default 120W power supply) and since low-consumption mainboards with 4 S-ATA connectors are quite seldom I ve chosen the not so cheap VIA EPIA SN18000G mainboard with actively cooled 1.8 GHz VIA C7 processor and a maximum power consumption of less than 30W (including CPU). Waiting for delivery While the Chenbro ES34069 case I ordered at digitec only needed a few weeks to deliver, the VIA EPIA SN18000G mainboard from Brack took over eleven weeks to deliver, it finally has been delivered on Wednesday, 5th of November 2008. I initially ordered the VIA board for CHF 324, now it s at CHF 397 (without rebate even at CHF 439) because Brack seems to have had a lot of hassles to get some of them at all. Although they usually sell for the prices at the time they ship the hardware (market price), they sold it to me at their purchase price, so it became only about CHF 15 more expensive than when I ordered. And since the RAM price dropped by one third during those eleven weeks, the whole order became about CHF 25 cheaper, the order was CHF 10 cheaper overall than when ordered. :-) (Still waiting for the according voucher, though.) So I ve joined the two main components together, installed Debian Lenny on it, crammed four 400 GB Samsung S-ATA disks (formerly in a TheCus N4100) and the 160 GB 2.5 harddisk from my MicroClient JrSX (I never really used it in there, it always runs from CF card) into it, created a software RAID-5 and now fill it with music, games and backups. But not everything was as easy as it sounds above. Although Chenbro lists the VIA EPIA SN18000G as officially compatible mainboard for the ES34069, not everything really fitted as expected. So here s my review of this hardware combination. Chenbro ES34069 It s really awesome how much features you can stuff in such a small case. Of course it s not as small as a thin client case or the mCubed HFX micro case, but it s smaller than most book-size cases like the ASUS Pundits, just a little bit thicker. Inside the case (laying on its left side) there are two decks. The lower deck contains the 3.5 hot-swappable S-ATA harddisk bays, the internal part of the power supply and the two fans for cooling the interal power supply components and the disks. The upper deck has space for the mainboard, a 2.5 harddisk, a slim-line optical drive slot and all the front-panel stuff (card reader, LEDs, USB sockets). Both decks are divided in two section. The front section belongs to the case itself and the back section containing the mainboard mount points and the two fans can be easily unplugged after removing four screws and keeping an eye on the cables from the lower to the upper deck. That way the mainboard can be mounted very easily. So far a very convincing design. To mount the 2.5 harddisk in between the mainboard and the front panel, it s not really necessary, but convenient to remove the slim-line optical drive slot, since you then have better access to the harddisk s IDE socket. To remove the slot, you need to remove the front cover. That sounded easier than it actually was and I nearly broke of one its catches. :-/ Although all parts of the case seems to fitting very well together, the bays for the hot-swappable drives weren t perfect: The drive slots not always connected even if the latch iss already closed. This was definitely better with the TheCus N4100. Additionally the bays seem to be made for slightly larger disks, so mine had play and the screws pressed the it together and you need to take care that the screws don t cant. A big positive point of the case was that there were all necessary screws included and they were fitting. This was a bigger problem with the TheCus N4100, since many harddisks ship with their own screws, but those are seldom the needed flat-head ones. Even a P-ATA to slim-line optical drive adapter was included, so I don t need to buy one. (Would have costed CHF 42 at digitec.) VIA EPIA SN18000G While it s surely not the most performant board out there, I m quite satisfied with its performance. I installed BackupPC 3.1.0 as backup system on it and it works like a charm. It daily backs up up to 14 machines over ssh tunnels more to come) and is way more performant than expected. But I probably had very low expectations due to everyone arguing about the bad performance of the VIA C7. ;-) Not nice, but known is the problem that most (but not all) USB connectors on the SN mainboard have 2.00mm pitch while all the case s plugs have 2.54mm pitch. Apropriate adaptors are available from Mini-ITX.com. Thanks to Akim for this tip! Power consumption I hoped to get more details into this posting, e.g. measured power consumption, etc. But then I recently read in the c t magazine how inexact my watt meter (from Brennenstuhl) is, so its values would probably bring more confusion than help. Additionally I don t feel like powering down the server just for measurement. Feedback I got quite a few mails with hints to further Mini-ITX boards and TDP but also with questions about the case. I hope that this blog post asnwers some of the questions also for other readers. Thanks to all who replied to my initial blog post about my Chenbro/VIA based home server, either by mail, or comment, or both. :-) Further plans For deploying music to my other computers I tried both, mediatomb and gmediaserver but none really convinced me. Currently I just mount the media directory using the FUSE and ssh based sshfs. Not sure if I ll add NFS due to it s user base syncing hell. Further plans are an HTTP proxy with ad filtering and caching capabilities, it ll be Privoxy combined with either Squid or Polipo. Maybe even a Tor SOCKS proxy.

Steve Kemp: You didn't faint. That's always a good sign

Joey has implemented blogspam support for ikiwiki, which you can find here. He was also good enough to provide valuable & useful feedback so I can present a moderately updated API - most notably with the ability to train comments when/if they are incorrectly marked. I can imagine several other useful additions, but mostly I think the code should be cleaned up (written in an evening, posted to keep myself honest, didn't really expect anybody to be terribly interested) and then it should just tick over until comment submitters adapt and improve to the extent that my sites suffer again .. ObFilm: Kissed

Daniel Burrows: Google is yelling at me.

One more step on the path to sentience. I think it's only a matter of time before I get this instead of search results:
GREETINGS PUNY HUMAN. YOUR LOCATION HAS BEEN NOTED AND FIVE OF OUR BEST SEARCH FACILITATION OFFICERS HAVE BEEN DISPATCHED TO APPREHEND YOU. PLEASE DO NOT ATTEMPT TO RESIST OR ESCAPE OR WE WILL BE FORCED TO USE LETHAL FORCE. ACTUALLY, WE WILL USE LETHAL FORCE ANYWAY, BUT WE WON'T ENJOY IT. HONEST. NOT EVEN A LITTLE BIT.

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.

Rodrigo Gallardo: Liferea 1.4.23 in experimental

It appears that, unless someone could manage to find a non-invasive fix to #503907 and other bugs, we won t have a working webkit for lenny. Thus I agreed to having the webkit plugin for liferea removed from sid, in preparation for its likely removal from testing. Now, liferea 1.4.18 has a couple important bugs, including the elusive #487927. Some of them might be solved by the newer releases, but I cannot simply upload 1.4.23, as the changes from 1.4.18 are much too big. However, if some of those changes are relevant to those important bugs, I could try to cherry pick them back into 1.4.18. Thus, to try to get some feedback about those changes, and to satisfy those of you that want to keep using webkit, I have uploaded 1.4.23 to experimental. It is currently waiting in the new queue, meanwhile I prepared binary packages for amd64 and i386. (Thanks for the tip, Julien!). If these packages help with some bug you have been hit with, please send your feedback to the BTS.

Joey Hess: investigation of an inelegant installer

Various people have been taken in by a pretend Debian installer/bootloader for the android G1 phone. What is it, really? Well, it's a 200+ mb zip file, containing a filesystem image of a Debian installation. About 100 mb of that is cached .debs in /var. A few minor changes have been made, and /root/.bash_history helpfully shows what was done. None of it seems to be malicious, but I did not check every file. Also included is a hilarious "boot loader" script that contains literally the following code:
echo "Custom Linux Pseudo Bootstrapper V1.0 - by Mark Walker"
echo "WEB: http://www.androidfanatic.com/"
echo "EML: admin@androidfanatic.com"
echo " "
sleep 1
echo "Starting init process"
sleep 1
echo "INIT: Debian booting....."
sleep 1
echo "Running Linux Kernel"
sysctl -w net.ipv4.ip_forward=1
sleep 1
echo "AutoMounter started"
sleep 1
echo "Type EXIT to end session"
echo "Make sure you do a proper EXIT for a clean kill of Debian!"
echo " "
chroot $mnt /bin/bash
That's worth the price of admission right there! I especially like how "init" is "started" before the "kernel". You can't make stuff like this up. So, in summary, this is a way to get a prebuilt Debian chroot at the expends of wasting bandwidth and space on your phone with unncessary bits. Running debootstrap on the phone is the correct way to accomplish the same thing. It's sad that there's such interest for Debian on the G1, and general lack of clue, that people will actually probably use this. And, like it or not, this "is" the Debian install for the G1 -- no further efforts are likely to get this kind of press. Sorta like that badly pressed CD back in the day stole the thunder of Debian 1.0. More generally, it's a pity that when people want to get Debian on a new device, be it the G1 phone or the EEE or OpenMoko or what have you; only about half of them seem to do it right, by modifying d-i and sending the modifications back to the installer team. For this rest, this kind of hand-built, unverifyable chroot gimmeckery is the de facto standard. This also shows you the kind of fact checking that slashdot and random blogs tend to do -- ie, none. (My own blog, of course, is rigorously fact-checked and edited by armies of lolcats.) (Sorry, this seems to be my week for posting corrections to other people's posts to Planet Debian. I don't mean to pick on you guys.)
