David Pashley: Comment Counts in Feeds and Updated Entries

Tim Bray just posted an entry about including a comment count in his atom feed. He said that he soon disabled it as people complained that it meant they saw the entry again as an updated entry. As I've recently done the same for my atom feed, I'm confused as to why this is happening. In my case I don't update either <published> or <updated>, just the <content> element. As the guid never changes, readers shouldn't consider it updated. Do readers really take a hash of the contents and consider it updated if it changes? Why do readers ignore the date fields. Is this affecting anyone? Certainly, it doesn't seem to affect Planet or the few readers I've tried it on.

Benjamin Mako Hill: Trademark Violation and Greater Evils

Biella Coleman recently mentioned counterfeit drugs in a blog post:
A pirated movie carries little consequence, except for that the movie industry may lose some cash flow. A fake Rolex purchased on the bustling streets of NYC saves you a lot of money (and robs you of a warranty). But counterfeit drugs, the consequences and stakes are at a whole other, more serious, order of things.
Biella's intentions in drawing the analogy are harmless -- people really do lose their lives because of fake drugs while rock-off movies and Rolexes are relatively harmless. However, her aside reminds me of the much less harmless, fair, and honest analogies drawn by Pat Choate in Hot Property who used examples like counterfeit drugs and dishonestly labeled aircraft parts to support a high protectionist position on IP. Because of the arguments made by people like Choate, I believe that there is a subtle danger in the type of analogy that Biella draws that I think we should try to guard against in the future. The danger lies in the fact that these comparisons tend to conflate at least two very different kinds of illegal activity. Trademark violations are illegal. So it selling drugs without approval from regulatory bodies. So is manslaughter and murder -- both terms used in the Times article Biella links to to describe the actions of drug counterfeiters. Laws in most countries already prohibit all of these things and offer increasingly harsh punishments for each action. In fact, selling unlicensed drugs and killing people is much more illegal than violating trademark and making knockoffs. And it should be. When someone commit IP violations in the process of committing much worse crimes, we should focus on highlighting, condemning, and punishing the much worse crime, not the IP violation which in comparison is almost inconsequential. The punishment for counterfeiting drugs may only be a slap on the wrist and that's probably an appropriate punishment for the counterfeiting component of the crime. The other worse crimes that the counterfeiter is also committing should be punished much more harshly. If, as the Dr. Reggi quoted in the Times article complains, "counterfeiting a medicine can be [only] a misdemeanor," we need stronger laws against selling unregulated drugs -- not stronger IP laws. If we confuse and compare bootleg movies and knock-off Rolexes with fake malaria or AIDS drugs, we're likely to come to the opposite conclusion. Our reactions to such situations should be, "People are killing people with fake drugs! We need stronger laws against killing people in these ways." They should not be "People are killing people with fake drugs! Interesting to note that they are also violating trademark laws like other counterfeiters." The former reaction will frame the discussion in a way that lets us treat the bad components of the crime more harshly and will not help IP high protectionists argue for stronger IP through a disingenuous process of guilt by association.

Lucas Nussbaum: State of software for Suspend to RAM/Disk ?

Dear readers, I am the mostly happy owner of a Dell Latitude D610 (the one with the ATI video card), running Debian Etch. I installed the hibernate package to try to get Suspend to RAM and to Disk to work, and Suspend to Disk worked out of the box. But Suspend to RAM didn’t work (garbled screen at resume). I never bothered to investigate this until today, when I discovered that acpi-support provides the same functionality, and works both for Suspend to RAM and to Disk ! I’m happier now, but I would like to understand, and the world of ACPI and Suspend to RAM/Disk is very difficult to grasp for newcomers. What is the story behind hibernate and acpi-support ? Why was this duplication of effort needed ? Also, it seems that gnome-power-manager and kpowersave provide the same functionality. Why can’t they just call the relevant acpi-support or hibernate scripts ? How do those different implementations compare (what are their main differences ?) ? Looking at the packages content, it seems that hibernate tries to be generic, while acpi-support gave up, and handles each and every laptop model differently. Correct ? Also, hibernate seems to be handling a few things better, like getting my network interface back up after hibernation. Finally, the last question: how do one debug Suspend issues, when it fails to work ? Is there a document somewhere explaining that ?

Sven Mueller: Dual boot and full encryption - Part 2

In my previous post about “Dual boot and full encryption“, I talked about the difficulties of combining full disk encryption for Windows with the option to dual-boot into Linux. Thanks to Jari Eskelinen (who probably is the anonymous user who posted the link to his page in a comment to my original entry), there now is a solution for this problem, at least for DriveCrypt Plus Pack from SecurStar GmbH. I will try this solution soon and it’s likely that I will blog about the results.

Benjamin Mako Hill: Novartis, Stop It

Swiss pharmaceutical company Novartis is currently suing the Indian government over its patent law in an effort to further limit production of generic drugs in India. Among other drugs, the company is trying to stop India's production of generic AIDS medicines that supplies more than half of the developing world. M decins Sans Fronti res (MSF) has a great FAQ and bunch of other information on their access to essential medicines (AEM) site that you should check out if you are unfamiliar with the case. Mika has been working on a variety of AEM projects for a while with quite a few important successes. From a certain perspective, some of the core calls for access to knowledge share common ground with free software, free culture, and anti software patent advocacy that I've been involved in. Of course, it puts things in perspective to see Mika and others in the AEM community point to millions of people and say that those people will die because of an IP maximilist position. Last week, I went with Mika to a protest of Novartis near MIT. It was just below freezing, slushy, raining, sleeting, and probably the worst weather I've ever experienced in Cambridge. Despite all that, it was wonderful to join a large group of activists in Cambridge/Boston and around the world to send a strong message to Novartis. You can watch a video of the protest or see a set of photographs. Both were taken by my friend Jay.

Eddy Petri&#537;or: I hope they don't see this

Now this is interesting, it seems that there is little spam with a subject pretending to be an answer.

BTW, I don't understand where the percentages come for, judging by the nuber shown, they don't make sense...

And in case you are wondering, this is mnenhy.

Wouter Verhelst: FOSDEM booth: more volunteers needed

Yesterday, I sent out an email to the debian-events-eu mailinglist, to ask for more volunteers for the FOSDEM booth next weekend. The situation is a little less desperate now than it was yesterday, but I would still need about 5 extra people who would want to put in one our at the booth. Manning the booth at FOSDEM is not hard; you need to know a bit about Debian to be able to answer questions (which means that you don't even have to be a Debian Developer), and be sure to be at the booth for your designated hour. I fully expect you not to be there all alone, but you will have final responsibility for the stuff that's at the booth during your hour, and you are not to leave it, just in case everyone else does at some point, because of a rather interesting talk, or the keysigning, or some such. If there are interesting things which you definately don't want to miss, then just let me know the hours that would work for you; I'll consider them then when I put you on the schedule.

Daniel Baumann: Debian Live Encryption

In the past, the (compressed) filesystem image was always unencrypted. Thanks to a patch from Sebastien Raveau, live-package 0.9.22-1 and casper 1.81+debian-2 now supports encrypted live filesystems through loop-aes.

Jordi Mallach: Rjukan, again

Very early tomorrow I'll be flying to Oslo for my second week at the Telemark. The only fixed plan for the week is to do ski daytrips all over the Gausta area, and, maybe, attempt topping it if my skills with the Telemark skis are good enough. I don't think so, though. Unlike two years ago, the weather will be a bit less gentle, according to the forecast. It is expected there'll be snow and under -5 C next Tuesday at noon, when we'll be out in the forests. Eww! While I planned to hang around Oslo with Tollef while we waited for our bus to Rjukan, it seems this year we don't have that much time to kill. So, depending on how tight the return is, I hope we can at least have a beer next Saturday instead! Keep an eye on your e-mail.

Christian Perrier: And the target moves again: twiki

So, today, as I was about to NMU atokx2, the twiki maintainer decided it would be time to slightly rewrite his debconf templates. And, therefore, we end up with two fuzzy strings (and still bad templates for that package anyway). So, the target moves again away from me and I will have to deal with a round of translation updates, templates rewrite and probably some more explanations with the maintainer. I don't doubt this will suceed but, of course, in the meantime, I can bet that another maintainer will have the weird idea to change his/her debconf stuff. It's really time for me to buy a real hard cluebat...:-) Meanwhile, I'll try hunting a few packages that are still not using po-debconf (except of course the desperate case of qmail).

Biella Coleman: I cite, you cite, I rant

Since there are few topics about academic etiquette than get me as excited as the norms of citations, I was quite fascinated by Joseph Reagle’s blog entry on the topic, a discussion that spanned a summary of Helen Nissenbaums’ work on the subject to his own wrangling with how he should recognize others who have independently reached similar conclusions as his own. Citations fascinate me because they are one of the few tangible inscriptions that reveal just how much of our work is indebted to others; it is stimergic (and if you don’t know what that is, read Joe’s entry as his moral wrangling over citations had to do with this term, his use of it and the discovery that someone else came up with it also). Despite the fact that all disciplines use them, we use them slightly distinctly. Lawyers use them in lawyerly-like ways: they cite the crap out of everything (it is kinda annoying but kinda helpful) and this makes total sense: they are covering their asses (lawyers know how to do this well), they are following the logic of their own practice as case law is quite citational, and well, law professors usually have one if not two research assistants, and this I am sure helps them in covering their citational bases. Another big difference in practices of citations is between a conventions that includes the name of the person you are citing in the body of the text and those that stuff all that data in a footnote. I can’t stand the later convention, not only because it is a pain in the neck to have to go back to the footnote JUST to see who the heck the author is citing but I think the credit should be right there, springing off the page so that the politics of collaborative recognition are, well, very evident (and I do understand that if you are citing a buttload of folks, that sometimes it is just better to do that in footnotes and sometimes with history they are citing way to may folks to really do it effectively in the body of the text). Joe raises some fundamentally thorny questions of who and how do we cite given that we may come up with an idea with the power of our own little brains, only to find out (gasp) that others, past and present and very unknown others, say something similar. On the whole, I tend to try to make clear, as Joe did in the example he provided, where I am totally taking the idea from someone to apply to another idea of mine and where I have an independently crafted idea and I am citing others so as to support my own position, which usually only strengthens my own argument. And what I find is that just because a cohort of folks may be working on similar topic (open souce, hackers), since we do so from our own perspectives and methods, most of the research will be original, though not as much as we tend to perform to our superiors. Also I sometimes find myself with an idea, which I consider as my own, but where I am so in need of a citation because it is an idea that seems at an intuitive level to be right on but it is hard to truly substantiate with the data I have (I am in that position right now and am desperate to find someone who says what I say and thus have a means to support what otherwise seems like a lofty idea…) And in fact, one thing that bothers me about citations is that we don’t seem to take seriously that the date of publication may not just tell us when something was published but help us gauge if something can become “dated.” What I mean is that when (and I guess if) I publish my book on hackers and Debian, it will not be a reflection not of some timeless aspects of hacking but firmly based out of the time period (roughly 10 years give or take 3 or 4) that I was either researching and writing about the topic. And while you can and should cite folks who wrote stuff in the past because that stuff still matters (a lot of what Steven Levy says for example still holds water) a lot changes. And yet I can’t stand how folks then cite someone as wrong when in fact all that went wrong is that time does what it does best: MOVE FORWARD and social phenomenon change along with the passing of new moons. This is not as likely to happen in the hard sciences but sure as heck happens with anything in the so-called human realm (which is why it bothers me that the social sciences and humanities model our citational and journal practices so similarly to the hard sciences, when it seems there are enough differences to warrant more differences than there are but that is a whole other topic). So now I try to note where my analysis diverges because the context so radically changed and really leave critique for those things I can safely and fairly disagree with on its own terms.
Finally, Nissenbaum’s article seems so interesting (I have not yet read it but now will) because it confronts how our practices of citations may or may not (or should) change in the face of a proliferation of access to work due to electronic media (she flags: wildcat publisher, grey literature, preprints). But I have found that, at least in anthropology journals, and especially in the anthropology of science, technology, and medicine, authors are mostly citing other anthropologists, as if a whole scholarship on a topic was non-existent, which seems more odd today when it has gotten easier to mine and find this stuff. They only cite “non-anthro others” when these folks are so standard, it would look horrible not to do so, but there is not a move to branch out, which I find a real shame and why I sometimes get really down on disciplinary journals (and why I am quite content to be joining an interdisciplinary department). And to be clear, I don’t fault individual authors, it seems that this is the unstated expectation and if that is what is going to get you in a journal, and that is what gets you tenure brownine-points, then you do as everyone else does. And that brings me to the final point which is the problem with standards in citational practices. So for example in the field of science studies, everyone must and usually does cite Bruno Latour. And as Chris Kelty reminded us, there is *very* good reason to. But I find what happens is that once a person is flagged and gets cited ad nauseum (which is mostly a decent but not full proof baramoter for judging good work), it become self-perpetuating reality/cycle because everyone else is doing it and it seems weird if you don’t (and I have sometimes seen some articles just awkwardly cite famous people in their discipline when it made little sense to do because, I think of this phenomenon). So all of a sudden, it becomes all Microsoft-Windows like: you cite, they cite, and it becomes “standard” who you cite and you can’t seem to escape the default. But alas, there is always an escape hatch, because one of the gems in academia is discovering that one theorist or book relate x to y and z topic that for some reason everyone else overlooked (because they were busy citing Latour,) to bathe some topic in a wholly new light and then a whole group of folks become unfashionable and the cycle begins, yet again…. The solution? If we only had a couple of research assistants like the lawyers, well maybe we could branch out a little and cover our bases a little..

David Welton: Caching &quot;streamed&quot; content in Rails

In a previous article, I illustrated one way of generating streaming content programatically. The application utilizing it is still slow in sending it, though, because it's got to interact with the database, process the data, and so on. The ideal solution would be to cache it, however, the normal rails cacheing solutions don't work, because the return value is a Proc, and if you try and write that to disk, it just writes the equivalent of proc_object.inspect, which doesn't do me much good. However, I figured out a clever way of running the exact same controller method "standalone", and stashing the results to disk. I placed this file in scripts/cacher:
#!/usr/bin/env ruby
ENV['RAILS_ENV'] = ARGV.first   ENV['RAILS_ENV']   'development'
require File.dirname(__FILE__) + '/../config/boot'
require "# RAILS_ROOT /config/environment"
require 'console_app'
app.get '/mycontroller/big_results_method'
resp = app.controller.response
File.open("# RAILS_ROOT /public/cached_big_results.csv", 'w') do  out 
  resp.body.call resp, out
end
I think it could be improved, because it seems to be running the DB query twice - once during the actual app.get, and once again when the Proc is called. But, in any case, it works, and now I can call it from a cron job.

Jordi Mallach: Tunisia

Last month, Bel n and I managed to secure our trip to Tunisia on the very last moment. So, planning trips on the very last moment isn't nothing new around this place, but we made a big effort to take things to the limit. I can't remember why exactly, but on January 31 we were *so* close to fucking everything up before it started, when we packed our stuff just a pair of hours before having to leave to the train station. My luggage was prepared in a rush, so while I think I took everything I thought I'd need, I didn't really select my clothes too much. The idea was to have our suitcases mostly empty to bring back stuff from the markets: smoking cachimbas, lamps, leather stuff, etc. At that time I didn't know that would end up being a great strategy. Anyway, like 9 minutes before the train's departure we were stuck in Nuevo Centro without a taxi and at that point I really had lost hope about being on time. For some reason, there were no taxis in the area, when it's normally a place where there's tons of them. Suddenly one appeared, we rushed in and I asked the taxi driver to please fly to the station. Happily, we got an incredible green wave around the avenues, he drove us at like 80 Km/h and we even had to wait for a few minutes at the station. In Barcelona, we prepared our small New Year's Eve dinner with my cousin Laia and Marc, and while the plan was to go to sleep pretty early to be in good shape to go to the airport next morning, the bottles of wine and cava emptied quite fast, and around 4:30 we were quite drunk when we decided it was enough. When some annoying sound woke us up next morning, it was really late, so we again rushed out to the empty streets of Barcelona, sneaked into a regional train, without knowing it was the only way to get in time in El Prat airport, and after some initial confusion trying to find the travel's agency desk in the wrong terminal, we managed to check into our flight, being the very last to do so. With all the rush, I couldn't get some clothes from my suitcase transfered into my hand luggage, which I really wanted to do after my nice lost luggage experience during Debconf 5 in Helsinki. Anyway, chances are small that your luggage gets lost, right? But of course, Murphy is always vigilant, and this was a great opportunity to fuck me up. After a short but horrible (due to our really bad hangover) to Tunis/Carthage airport, we were in the long security/passport check. When Bel n picked up her bag and mine didn't appear, I tried to tell myself hey, it'll appear, no worries! . After 15 minutes, the stupid suitcase was nowhere to be found. Apparently, another two pieces of luggage had the same luck, which made us contact a group of four Uruguayans who were missing one of them. Nothing too terrible; it'll surely come on tomorrow's flight. After reclaiming our lost luggage, we went out to the parking where a bus was waiting for us, and on the way there, the six of us nearly fell into the first Tunisian scam, involving a dude selling jasmine flowers at 2 each. The bus took us down to Jasmine Hammamet, the most touristic place in Tunisia. Valencians might have an easy imagining the atrocity of the area by picturing what twice Marina d'Or plus Benidorm including Terra M tica would look like. Kilometres and kilometres of a disgusting Who can build the most horrible giant hotel right next to the beach contest. So it was pretty clear we had to spend as little time as possible in the area. We soon learned about how transport works in Tunisia. The cheapest is to use the public busses and the luagge collective taxis, we soon found out. Our first morning there, our guide Rejeb, working for Iberojet and Solplan touroperators, gave a talk where he advised us against travelling alone, specially around the South, while he offered organised trips around the country for every day of the week. Although we expected this danger! speech, we decided to book the two day trip to the South and Great South of the country, basically because it was the best way to see many places in a short time, even if it meant having limited time in each destination. We wandered around Jasmine Hammamet and discovered Carthage Land, sort of a Disneyland set in the age of Anibal and Carthage's empire, which was inside a newly built medina complex. This was a really bad place to practice the art of haggling, as the place was so desert, merchants really tried hard to get you buy something. Again, we were close to fucking up after our first negotiation, but we finally decided we weren't so interested. Lucky, we later found out the price was outrageous. Sadly, we spent way too much time in that tourist trap, and we found it was too late to go to the real Hammamet town to see a real medina and real stuff, so we had a long walk around the immense beach until sunset. On Wednesday, we did organise a bit with the Uruguayans and some others we had met: Mar a and Santi Kuchi Kuchy , Cristina and Pedro and an Argentinian family, and managed to hire a van driver to drive us all over the North. For quite a good price, we were taken to a few ruin sites in Carthago, now mostly a residential area, and it was really impressive. While the condition of many of the remainings is not optimal, it was exciting to see things which had been built by Phoenicians and Romans 2,000 years ago. I really enjoyed the remainings of the Antonine thermal baths of the city. It had been a huge building right next to the sea; one of the standing columns helps figuring out how big it had been. Right next to this site, the Presidential Palace dominated the whole gulf. Military places are treated zealously in Tunisia, and it is against the law to take pictures of any bit of it, not even a barbwire of the fence. The Palace had a great Tunisian flag waving over it, and many signs advised you against taking pictures in that direction. I couldn't resist.


The ruins of the Roman Antonine Baths After Carthage, we went to Sidi Bou Said, a small touristic town, which had the peculiarity and beauty of having all windows and doors painted in a beautiful light blue colour. Our last stop for the day was in Tunis, where we visited the most amazing medina of the whole week. Unlike the new medina in Jasmine Hammamet, this one was literally packed with people going up and down the maze of very narrow streets. Every few metres you'd come across a new, attractive smell coming from the few salons de th or spice, leather or perfume shops. Here we finally started developing our haggling skills, and managed to get a few items for reasonable amounts.


Streets of Sidi Bou Said Back at our hotel, everyone tried to get a quick dinner and go early to bed, as next morning we were taking a bus for our trip around the South. There was time to call yet another time to the Airport, to find out that one of the luggage pieces had been found. While there was no news about my suitcase, we shared a taxi to the airport to pick the found suitcase, and see if mine was actually there by any chance. Unluckily, it wasn't, so I wouldn't have any clothes for the desert visit. Some people in the group were kind enough to lend me some t-shirts and pants. For my underwear, I actually resorted to using some of Bel n's (no kidding, it was way too sexy :P), while mine dried up after some manual washing. The alarm clock went off at 5:15 or so, and soon after we were ready in the hall with our small bags. When the bus was ready to pick us up, the guide said we weren't allowed in, as we weren't on the list. WTF? We were nearly the first ones to book and pay for it! So he finally let us in, for a short while, until he realised there was no space for everyone, so he demanded that we got off. Of course, we didn't, and a long and very disgusting argument started between the guide, us and a few people who had seen us pay for our trip, and were trying to support us. To make a long story short, we ended up stepping down when I noticed the bus driver calling the police, and after Rejeb, our guide, told us the other bus would be waiting for us at the travel agency if we quickly took a taxi there. We of course knew that was a fantasy to get the bus moving, but dealing with the police at 6:30AM wasn't on my list of activities for the day, so we finally gave up to let the rest of the people get in time to their visits, as they were very tightly scheduled to make everything fit in two days. Nobody was waiting for us at the travel agency, but we were promised our money back, which did happen in the evening; our plans for Thursday and Friday were a bit broken though, and the rest of the morning was spent looking for alternatives. When we had managed to book a new trip in a different agency for Saturday, we took the bus to Nabeul, the capital of the province, well known for their medina specialised in pottery. In Nabeul, we lived a tourist trap which I found to be quite original. Not having walked 3 metres into the city walls, some young dude stops us and tells us that he knows us, as he works in the restaurant of our hotel . I totally didn't remember his face at all, but why not? So he quickly tells us Nabeul has good carpet workshops, and her sister is working in one which is regulated by the Government, and you can only visit two days a week. Coincidentally, Thursday is one of them! So he literally grabs us by the arm and takes us to one of the streets perpendicular to the main market street, and we enter a carpet shop. To the right, his sister probably being like 45 years older, is knitting a nice carpet on the loom. And a few seconds after, we're taken upstairs, where a Teletienda show starts before us. Without being asked if we want to buy a carpet, some other dude starts to unroll carpets and more carpets before us, talking in some very basic Spanish. While we're offered jasmine tea, which is really nice, Ali the brother quickly excuses himself and vanishes, leaving us with the salesman, which continues unrolling more and more before us, now helped by someone else. When 10 minutes later we convince them that we won't buy any carpet, he asks a donative for his young employee, who has unrolled and will now roll back a zillion carpets. Back in the hotel, we have dinner with a pair of Catalans from our flight, and when we tell us about the carpet place, they tell us they went over the same story like one hour before us! On Friday, we got some advice on other places to visit, and decided to go up to Cape Bon and visit Kerkuan, the only important remainings of a Punic city which, when conquered by the Romans, was destroyed to the grounds, but not rebuilt on top (they were busy with Carthage). Romans did an excellent job when destroying cities, and the result is a site which still lets you see perfectly how a small town (around 1,500) looked like 2,000 years ago.


Ruins of a Kerkuan neighbourhood, with their red bathrooms nearly intact To reach Kerkuan we had taken the bus up to Nabeul and then our first luagge to Kelibia, where we took a taxi (after no less than half an hour arguing in French with the taxi driver to settle on a rate for a ride to Kerkuan and then to the tip of the Cape in El Haouaria. Luagges are undoubtedly the best way to travel medium distances for very little money, while getting mixed with locals. During our ride up North, we chatted with a nursing student from Kelibia who was going back to her town for the weekend. She was really open, like most of the people we found in Tunisia, and we ended up exchanging our post addresses; we still need to send her a postcard from Val ncia soonish. This area wasn't so touristic, so the roads, while totally acceptable, weren't as good as the highway from Tunis to Sfax we were used to. We had seen some bits of the local driving skills , but the luagge driver performed some of the most extreme overtakings I've ever seen. These happened every three of four minutes, so after a while I was actually amused about what was going on. We would overtake two lorries on one go when there was absolutely no visibility; if things went too far, people would just slow down to let the overtaker get back into his lane on time, and those coming ahead would just use their headlamps to make them know it was just a bit too close. The taxi driver, annoyed at us, took us to Kerkuan but didn't wait for us; he immediately left, leaving us without any transportation in the middle of nowhere. After a visit at the site, we walked around 2.5 kilometres back to the main road, where we decided it was too late and risky to continue the journey up to El Haouaria, so we waited on the road gutter for a taxi. The first one which stopped was, to our surprise, the same bastard who left us one hour before, who stopped, laughing at us a little. Luckily some other taxi came by in the correct direction, and soon forgot about that man. After a taxi, luagge and bus ride, we were back in Hammamet, and the desert group had already got back from the two day trip. We were asked over and over what happened, what did we do, etc. People who hadn't talked to us before would come over and see; we were really surprised about the warm welcome we had. After dinner, we improvised a customes party, and many people managed to dress up in Tunisian/arabic fashions using bed sheets and so on. We had to wake up at 5AM next morning, but didn't go to bed until 2AM. Nothing could go wrong this time. We had our tickets, we had confirmed we would be going on Sunday the night before, so at 6:15, our new guide came in, and came straight towards me. He said something in German, and after I told him I spoke absolutely no German, he said huh, well you know the bus is full of Germans, and my indications will be in German? . Pretty incredible, but again a fuckup by the agency. My ticket said, clearly: Sahara safari. Bus + 4x4. (ALL). Turns out ALL meant Allemand, not everything included , although we had requested English pretty clearly. This was quite a minor problem though, after having no clothes for a whole week and having been left behind two days before. I think we were really lucky getting that German group, though. We were only 16 people on the minibus, making the stops a lot faster than the normal ones, where 55 persons need to get out and in of the bus. We had our own Routard guide for Tunisia, so we could read about the places we were about to visit before getting ther. Also, I surprisingly knew much of what our guide was talking about, just missing the details he talked about oil production in Tunisia compared to Spain's, among other topics . When the landscape was becoming drier and drier, Bel n and I spotted something dark far away ahead in the completely straight road. As it became bigger, I started thinking it might be the #1 place to visit for me in Tunisia: El Djem's impressive Roman amphitheatre. When we got off the bus, I was totally excited. Before me, the walls of an incredibly well preserved, huge Roman building; in fact, the best Roman ruins in the whole continent. El Djem's amphitheatre was the third biggest of the Roman empire with 35,000 seats, only surpased by Rome's and Capua's. It remained mostly intact until the 17th century, when some of its stones were used to build the city and some of the treasures taken to the Great Mosque of Kairouan, but when it took more damage was during two consequent wars, when the Turks didn't have many problems to blow part of the wall away using cannons to end up a siege of the city.


The Roman amphitheatre of El Djem The underground tunnels are intact, and it's difficult to not have flashes of Gladiator while walking under the arena's trapdoors. Sadly, there was little time to spend there, and we had to continue the journey after just 45 minutes. I would have spent half of the day there. From here, the landscape truly started to get drier and more desertic. The south of Tunisia is a giant olive field, until you reach the Great South, where it's dry enough that the only thing that grows in the land are rocks. Hours later we arrived in Matm ta, the very famous troglodyte village of small holes in the ground. Although I was curious about being there, watching how organised and massive tourism has destroyed these Berber's ways of life dissapointed me greatly. Our guide stopped the bus in one of the pits, which was decorated with white and light blue. In the first room, an old woman was grinding something in a small, stone mill. The dwellers of the few pits still used by their original inhabitants now make a living by letting people into their homes and getting dinar as a payment for taking photographs. What the woman was doing was just a bit of theatre, part of the show. After this first room, we got into the middle of the pit, which had a series of other passages to some rooms, some of which were simply open so we could get in and have a look. I felt a little bit like violating someone's privacy, and wondered how much the house had changed in the last years.


Inside a troglodyte underground house in Matm ta After our visit, we continued up the mountains of Matm ta, and after going by a giant "WELCOME TO MATMATA" sign drawn in white in the middle of a mountain, Hollywood style (!), we stopped for a brief photo-stop (sic). Indeed, the view was quite impressive, and is universally famous as one of the filming spots of Tatoonie scenes in Star Wars: A New Hope. Speaking of famous places, a few minutes later we stopped at the top of one of the hills, were we'd have lunch in the Hotel Sidi Driss, a place of pilgrimage for Star Wars fans, as it was the troglodyte pit which served as the Skywalker's home. The place is full of references to the film saga, and one of the open pits is full of set pieces stuck into the walls. We were served couscous, which wasn't bad, but was cooked and served in the most genuine fast-food fashion. Everyone there gets couscous to eat, apparently, and it's the same in many other touristic places in the area.


Matm ta's lunar landscape From here, our journey headed straight West, in the middle of the rocky desert, until after some time, you could start to see lines of palm tree branches planted here and there, a sign that rocks would soon disappear, being replaced by sand and dunes. As when we were approaching El Djem, at some point a huge, dark spot appeared on the horizon. Douz, probably named after some 12th French batallion which stayed there, is a small town in the very limit of the Sahara desert, built right next to a huge oasis, exclusively dedicated to palm tree plantations, making dates production a big source of income, along with, of course tourism. The travel agencies use Douz as the starting point for several-day trips into the desert, camel rides and stuff like this. Our guide offered us getting a camel and carriage ride in Tozeus for 20 dinar, but Bel n and I declined. He didn't seem to be too happy about it, and had no problem commenting this in German and Arab with the driver (Spanisch and Spanien were clear to me). We learned that the agency (or the guide) makes around 3 Dinar for everyone who contracts the camel rides, after speaking to one native young kid who worked in the camel place. While our German trip mates got dressed in berber fashion, we opted to walk into the desert and play around in the sand on our own. I discovered a few desert insects which were unlike anything I've seen anywhere, and their diminute trails were all over the dunes. Looking West, the view was astonishing, with only thousands of kilometres of yellow dunes ahead us.


The evening sun over the dunes After they came back, we were taken to our hotel, which was really impressive. After leaving our stuff in our room, we headed back to the desert, which was like 300 metres away, to see the sunset over the Great Dune . There's a street which literally serves as the frontier between the rocky ground and the sand desert. From there, you could see many lines of palm tree branches, which are planted by locals in a futile attempt to stop the inexorable advance of the desert. Women in Douz and other towns in the desert limit spend their days sweeping the entrances to their homes, as sand gets in really fast. A small village next to Douz even had to be abandoned and rebuilt in some other place, with the old one being finally devoured by the dunes. When it got dark, we still had some time to kill before dinner, and we discovered a hammam in our hotel. I got in, and saw there was a bored young man inside. He informed us about the prices, and after some short deliberation, we realised we'd spent half of the camel money in some Arab relaxation; while I got a really cool massage, Bel n enjoyed a Turkish bath. I spoke to the guy for a while, and he said not that many people used that hammam. He actually handed the list of services since 2002, which easily fitted in one piece of paper. People don't know what they are missing; he explained that most of the hotel's clients just showed no interest in the baths. I wonder how Fins or Norwegians would react, given their sauna culture. The dinner and breakfast in that hotel was absolutely awesome, and I actually ate too much to have an easy sleep. Next morning we had to be ready at 5:30. That's pushing my limits. The bus started crossing the Chott Jerid when it was still quite dark. The chotts are dry, salt lakes in the middle of the desert, which during some seasons do get some water, sometimes from the underground. The Chott Jerid is the biggest of the three chotts in the area, and the views are fantastic. It's like a giant, totally flat muddy sea which reflects light creating dangerous mirages of oasis-like dark patterns. Before the construction of the recent road that links Douz and Tozeur, crossing the chott was so risky that many people died in the attempt. We had the unique opportunity to see the sun rise over the salty horizon.


Sunrise at the Chott Jerid Again, on our way to Tozeur, we were offered a carriage ride for ten dinar, and again we declined. The guide then asked us if we had no money or what. So in Tozeur we basically wanted to walk around the oasis fields, and ended up talking most of the time with some old man who sold drums and desert roses. On a 4x4, we went up North to Chebika, a really cool town with a small oasis of thermal water, which I guess was around 40 C. The short walk to the wall where the oasis surfaced was packed with children who insistently begged for money or offered necklaces and other items. It was difficult to make them understand you didn't want anything. We then went up the mountain behind Chebika through a road which had its own piece of history. It seems that during WWII, Rommel suffered an Allied siege in Chebika, with a range of mountains behind their backs. The Allies gave him one month to surrender, and he took his time to answer. During that time, he ordered his engineers to design and build a road which would let them escape Chebika through the steep mountains, and they managed. When the ultimatum expired, the Allies apparently found out Chebika had been abandoned by the Germans, including tanks and most of their equipment. So, on the way up, a few kilometres away from the Algerian border, there was another typical visit to the biggest oasis waterfall in Tunisia, which was several metres high.


The oasis at Chebika Our Sahara trip would soon end, and after lunch we headed Northeast on our way to Hammamet. On our way back, we stopped in Kairouan, one of the key Islam pilgrimace spots, with the Great Mosque as the biggest attraction. Unluckily, as we arrived after lunch, we didn't had a chance to see it. Apparently it is really impressive. We haggled a bit for a pair of babouches and a small leather couch in the medina. We came back to our hotel around 7, and found most of the people around the hall. After the obligatory update on how it went, we went to bed as we were exhausted, and of course we had to get up really early to head to the airport. The airport was at that early time of the morning a total chaos, and while people stood in the checkin lines, I tried to find out what was going on with my still lost luggage. I went back to the lost luggage window, which would be closed for 5 more minutes. When they finally opened, they told me once again they had no clue about what was going on with my luggage. I finally understood they had no clue: my tracking number wasn't in their database. I asked them if I could have a look at the unreclaimed luggage storage room. They kindly opened a small door for me, and invited me to go inside and have a look. The view was gross: hundreds of lost bags all over the place. As I was in a bit of a hurry (I actually had to get back to Barcelona), I asked him where to find the bags of one week ago, and he nearly bursted into laugher. Okay, I had to look all over the place, scanning every piece of luggage in an attempt to spot mine. There were bags of absolutely every type in there. In one of the corridors, I sensed a disgusting smell, and figured out some poor guy may have food or something in one of their lost bags, which was rotting in that horrible room. So wrong: soon after I found myself nearly stepping on a puddle of shit, as if someone had literally dumped it right there. Oh my... luckily my search was nearly over and unsuccessful, and I got back to Barcelona with the hope of finding my bag in El Prat. After looking in their two storage rooms I realised I'd probably not see the luggage again, which is a real pain in the ass. A few hours of train later we were back in Val ncia, with a feeling of having spent 3 or 4 weeks in Tunisia, not just 8 days. Really a great place to visit, not only for their cultural treasures, both current and ancient, but for the openness of their people. I hope I'll be back at some point!

Erich Schubert: iCalendar is broken by design

Seriously, RFC2445 is on crack. No wonder that few apps handle recurrence rules properly. Let me give you some examples straight from the RFC:
RRULE:FREQ=YEARLY;INTERVAL=2;BYMONTH=1; BYDAY=SU;BYHOUR=8,9;BYMINUTE=30
These are tons of events: at 8:30 and 9:30 every other year, every sunday in january. That's not precisely what I'd call a yearly frequency... I mean, we're talking about every sunday in januar. I'd more call that like... weekly. And yes, this is the official solution:
"every Sunday in January at 8:30 AM and 9:30 AM, every other year"
Note that you can not do 8:30 AM and 9:00 AM. You could do 8:00 AM, 8:30 AM, 9:00 AM and 9:30 AM (using BYMINUTE=0,30). Pure crack.
Everyday in January, for 3 years:
DTSTART;TZID=US-Eastern:19980101T090000 RRULE:FREQ=YEARLY;UNTIL=20000131T090000Z; BYMONTH=1;BYDAY=SU,MO,TU,WE,TH,FR,SA or RRULE:FREQ=DAILY;UNTIL=20000131T090000Z;BYMONTH=1 Isn't that totally on crack? Using FREQ=YEARLY for everyday in january? Notice how the semantics of "BYMONTH" change? In the first case, it's creating multiple events (BYMONTH=1,2 would name january and february independently); in the second case it's used to filter out individual days. Let me explain that a bit more: FREQ=YEARLY;BYDAY=MO,WE means every Monday and Wednesday. See how the modifier makes about 104 recurrences out of a single year? FREQ=HOURLY;BYDAY=MO,WE means every hour, but only on Monday or Wednesday. In this case, the modifier reduces the hourly events by throwing out all that are on other weekdays, reducing the number of recurrences. Again, this is not my weird reading, but the RFC says:
BYxxx rule parts for a period of time which is the same or greater than the frequency generally reduce or limit the number of occurrences of the recurrence generated. [...] BYxxx rule parts for a period of time less than the frequency generally increase or expand the number of occurrences of the recurrence.
(Note that I didn't find any details on if they consider a week to be be "less" or "more" than a month, since there is no obvious subset relationship, but a week can overlap two months, and a month usually overlaps five weeks... So if I have FREQ=WEEKLY;BYMONTH=1;BYDAY=WE, is that Monday in every week overlapping January? Every week completely contained in January? If I'd want every Monday in January, I'd use FREQ=DAILY;BYMONTH=1;BYDAY=MO...) Intersecting or joining two RRULE specifications is usually impossible (try to write one rule that is 8:00 and 9:30 every day for convincing yourself that a join won't work, and try to intersect FREQ=DAILY;INTERVAL=3 and FREQ=YEARLY;INTERVAL=2...) Anyway, I'm truly not suprised that my mobile and probably many other applications don't handle recurring events completely (that is when importing from iCal they often just lose the repetitions). My own implementation is doing okay. There are still a few missing features (BYSETPOS e.g. which can be used to say "the second to last tuesday or thursday each month"; should be trivial to add however, just picking the appropriate indexes out of a list), and some odd corner cases to dig in the specs and resolve (e.g. "every other week on friday, starting saturday march 3" - are we talking in business weeks, or intervals of 7 days here? When talking in weeks, is it friday in the week containing march 3, or following march 3, since that day itself is not a friday!) Some of these details probably vary heavily from iCalendar-supporting application to another... e.g. FREQ=DAILY;BYHOUR=8;UNTIL=20070215T000000Z does this include a recurrence on 2007/02/15 at 8:00 (which is past the UNTIL time, however the hour of the UNTIL field is not used in presence of BYHOUR). If you ever design a language for specifying recurrences, please: Consider something like (intersect (repeat daily interval=3) (union (repeat weekly monday) (repeat monthly 1) ) ) (i.e. every 3 days, if they fall on the first of the month or on a monday) Also spend some time thinking about alignment: "Every monday in a week containing the 15th of a month." - months and weeks are not aligned; assuming a week being defined as Monday-Sunday, this can be any day between the 9th and 15th of the month (in fact you could specify this in iCalendar, but it's probably easy to come up with an example that is too difficult to represent in iCalendar RRULEs, albeit trivial to calculate.)

MJ Ray: Darling cheese head SPI was yards too greasy

SPI's February meeting (agenda) on Friday is approaching and the board seems to have gone all evasive and yeti-like. For yet another month, I've heard nothing in response to simple questions and over on debian-vote, board members posted a bizarre claim about how SPI acts for debian and a direction back to SPI so I've asked the board to confirm SPI's view of debian but this is all yards too greasy, really. I'm getting quite irritated with the question-avoiding and red tape from the board, as you can maybe tell from the tone of:
"In case anyone hasn't noticed, it seems very difficult to get anything like a straight answer out of most of the current SPI board lately. Try it for yourself. Fun for all the debian family. Knock one over, win a coconut and five tons of flax!"
There only seems to be one responsive sane board member at present and that's just not enough to ensure SPI members can exercise their right to oversee the board's work. SPI seems to be going delinquent again. Please correct it before it does much damage. Please, debian, postgresql and GNUstep developers in particular, please request your contributing membership and help get this organisation back on track.

Ingo Juergensmann: Goodbye Drupal, Hello Serendipity!

Or: my last blog entry in Drupal I'm migrating from Drupal to Serendipity, just because Drupal won't be released with Etch. I already blogged about this migration here and here. It's not because I don't like Drupal. I really like it. But as it won't be included in Etch, that's a real show stopper for Drupal and s9y is nice as well - and it even seems to have a better spam prevention than Drupal. So, when you've subscribed to my blog feeds, you'll need to resubscribe soon, because the domain will point to a different location and thus breaking the links. Maybe I'll keep the old blog under the subdomain "oldblog.windfluechter.net"...
If you want to take a first look, visit http://blog2.windfluechter.net/ (or while the DNS update is on its way). I apologize in advance in case of flooding planet.d.o!

Russell Coker: John Howard is bizarre

Our despicable prime minister said "I think that would just encourage those who wanted completely to destabilise and destroy Iraq, and create chaos and victory for the terrorists to hang on and hope for (an) Obama victory".

That statement is wrong in many ways, firstly the US (with Australian help) has destabilised and destroyed Iraq already. Claiming that removing US troops at this stage will do any further harm is unproven (and except for the Kurdish area extremely unlikely). Trying to link a presidential candidate with a terrorist organisation is the worst type of dirty politics.

Texas Republican senator John Cornyn requested that the Australian government stay out of US politics. It sounds like a reasonable request. But I wonder whether John Cornyn got involved when the US ambassador spoke out against the leader of the Labor party at the last Australian Federal election...

Senator Obama suggested that if John Howard wants to criticise his policies in Iraq then he should first send another 20,000 Australian troops (there are currently 140,000 US troops compared to 1,400 Australians). According to the CIA World Fact Book Australia has a population of 20.3M while the US has a population of 298.4M. If the ratio of serving soldiers was to match the populations then Australia would have 9,500 troops in Iraq. If Australia was to be a full military partner of the US (but scaled down due to the smaller population) and therefore had troops in South Korea, Japan, and Germany then the number of Australian troops committed might be closer to the 20,000 number cited.

But this is no criticism of Senator Obama. For a number that was made up to demonstrate his point that Australia is not pulling it's weight in Iraq it's a quite reasonable estimate.

The US Democrat Senator Ron Wyden correctly described Howard's comment as "bizarre". This may become a catch-phrase for the Howard regime (as the Bush regime is described as a "miserable failure").

Johnny seems to think that it's in his best interests to send Australians to fight a war that has no benefit for Australia (or the US for that matter), but he doesn't have the guts to do it properly. Fortunately for him the Bush regime understands his position and allows him to send a token force to demonstrate support without the risk of any significant number of casualties or having to conscript soldiers.

This mutual meddling in elections is a demonstration of the way Bush and Howard conspire against the interests of the Australian and US citizens. Both countries need governments that look after the interests of their citizens at home and let the UN take a larger role in world issues.
