Wouter Verhelst: DVD's ready

Yesterday, I was finally able to fetch this: Baobab DVD (plus 99 more like it) It's been a while since the concert back in march, which we recorded (with dvswitch); the reason it took that long was mainly due to a few organizational reasons where people who needed to order couldn't because someone else was delaying (you don't want to know). But the DVD's are now, finally, ready. I (really) like what they look like. There'll probably be a few leftovers, but I can deal with those.

Pietro Abate: bypassing the apt-get solver

Here at mancoosi we have been working for quite a while to promote and advance solver technology for FOSS distributions. We are almost at the end of the project and it is important to make the mancoosi technology relevant for the community. On goal of the project is to provide a prototype that uses part of the results of mancoosi that can based to install/remove/upgrade packages on a user machine. We certainly don't want to create yet another meta installer. This would be very time consuming and certainly going beyond the scope of the project. The idea is to create a prototype, that can work as an apt-get drop in replacement that will allow everybody to play with different solvers and installation criteria. A very first integration step is a small shell script apt-mancoosi that tries to put together different tools that we have implemented during the project. Roberto wrote extensively about his experience with apt-mancoosi a while ago showing that somehow the mancoosi tools are already usable, as proof of concept, to experiment with all solvers participating to the Misc competition. On notable obstacle we encountered with apt-mancoosi is how to pipe the result of an external solver to apt-get to effectively install the packages proposed as solution. Apt-mancoosi fails to be a drop-in replacement for apt-get exactly for this reason. The "problem" is quite simple : The idea at the beginning was to pass to apt-get, on the command line, a request that effectively represents a complete solution. We expected that, since this was already a locked-down solution, apt-get would have just installed all packages without any further modification to the proposed installation set. Of course, since apt-get is designed to satisfy a user request, and not just to install packages, we quickly realized that our evil plan was doomed to failure. The only option left, was to use libapt directly, but the idea of programming in c++ quickly made me to desist. After a bit of research (not that much after all), I finally found a viable solution to our problems in ''python-apt'' that is a low level and wrapper around libapt. This definitely made my day. Now the juicy details. the problem was to convince apt to completely bypass the solver part and just call the installer. First a small intro. python-apt has an extensive documentation with a couple of tutorials. Using python-apt is actually pretty easy (some snippet from the python-apt doco) :
import apt

# First of all, open the cache
cache = apt.Cache()
# Now, lets update the package list
cache.update()
here we open the cache (apt.Cache is a wrapper around the low level binding in the apt_pkg module), then we update the package list. This is equivalent to apt-get update . Installing a package is equally easy :
import apt
cache = apt.Cache()
pkg = cache['python-apt']

# Mark python-apt for install
pkg.mark_install()

# Now, really install it
cache.commit()
Now, the method mark_install of the module package will effectively run the solver to resolve and mark all the dependencies of the package python-apt. This is the default behavior when apt-get is used on the command line. This method has however three optional arguments that are just what I was looking for, that is autoFix, autoInst and fromUser . The explanation from the python-apt doco is quite clear.
mark_install(*args, **kwds)
Mark a package for install.
If autoFix is True, the resolver will be run, trying to fix broken packages. This is the default.
If autoInst is True, the dependencies of the packages will be installed automatically. This is the default.
If fromUser is True, this package will not be marked as automatically installed. This is the default. Set it to False if you want to be able to automatically remove the package at a later stage when no other package depends on it.
What we want is to set autoFix and autoInst to false to completely bypass the solver. So imagine that an external solver can give use a string of the form : bash+ dash=1.4 baobab- that basically asks to install bash to the newest version, dash at version 1.4 and remove baobab. Suppose also that this is a complete solution, that is, all dependencies are satisfied and there are no conflicts. The work flow of mpm (mancoosi package manager) is as follows : We already have a first prototype on the mancoosi svn. It's not released yet as we are waiting to do more testing, add more options and make it stable enough for testing. Maybe one day, this will be uploaded to debian. This is the trace of a successful installation of a package in a lenny chroot. The solver used here is the p2 solver

I think we'll keep working on this python prototype for a while, but this is not certainly what we want to propose to the community. The mancoosi package manager is probably going to be written in Ocaml and integrated with dose3 and libcudf. This will allow us to gain speed and have a solid language to develop with (nothing against python, but we don't feel that a scripting language is suitable for an essential component as a package manager). Time will tell. For the moment this is just vapor-ware ...

Petter Reinholdtsen: Lenny->Squeeze upgrades of the Gnome and KDE desktop, now with apt-get autoremove

Michael Biebl suggested to me on IRC, that I changed my automated upgrade testing of the Lenny Gnome and KDE Desktop to do apt-get autoremove when using apt-get. This seem like a very good idea, so I adjusted by test scripts and can now present the updated result from today: This is for Gnome: Installed using apt-get, missing with aptitude

Running apt-get autoremove made the results using apt-get and aptitude a bit more similar, but there are still quite a lott of differences. I have no idea what packages should be installed after the upgrade, but hope those that do can have a look.

Petter Reinholdtsen: Lenny->Squeeze upgrades, apt vs aptitude with the Gnome and KDE desktop

I'm still running upgrade testing of the Lenny Gnome and KDE Desktop, but have not had time to spend on reporting the status. Here is a short update based on a test I ran 20101118. I still do not know what a correct migration should look like, so I report any differences between apt and aptitude and hope someone else can see if anything should be changed.

Petter Reinholdtsen: Lenny->Squeeze upgrades, apt vs aptitude with the Gnome desktop

Here is a short update on my my Debian Lenny->Squeeze upgrade testing. Here is a summary of the difference for Gnome when it is upgraded by apt-get and aptitude. I'm not reporting the status for KDE, because the upgrade crashes when aptitude try because of missing conflicts (#584861 and #585716). At the end of the upgrade test script, dpkg -l is executed to get a complete list of the installed packages. Based on this I see these differences when I did a test run today. As usual, I do not really know what the correct set of packages would be, but thought it best to publish the difference. Installed using apt-get, missing with aptitude

I was told on IRC that the xorg-xserver package was changed in git today to try to get apt-get to not remove xorg completely. No idea when it hits Squeeze, but when it does I hope it will reduce the difference somewhat.

Petter Reinholdtsen: Lenny->Squeeze upgrades, removals by apt and aptitude

My testing of Debian upgrades from Lenny to Squeeze continues, and I've finally made the upgrade logs available from http://people.skolelinux.org/pere/debian-upgrade-testing/. I am now testing dist-upgrade of Gnome and KDE in a chroot using both apt and aptitude, and found their differences interesting. This time I will only focus on their removal plans. After installing a Gnome desktop and the laptop task, apt-get wants to remove 72 packages when dist-upgrading from Lenny to Squeeze. The surprising part is that it want to remove xorg and all xserver-xorg-video* drivers. Clearly not a good choice, but I am not sure why. When asking aptitude to do the same, it want to remove 129 packages, but most of them are library packages I suspect are no longer needed. Both of them want to remove bluetooth packages, which I do not know. Perhaps these bluetooth packages are obsolete? For KDE, apt-get want to remove 82 packages, among them kdebase which seem like a bad idea and xorg the same way as with Gnome. Asking aptitude for the same, it wants to remove 192 packages, none which are too surprising. I guess the removal of xorg during upgrades should be investigated and avoided, and perhaps others as well. Here are the complete list of planned removals. The complete logs is available from the URL above. Note if you want to repeat these tests, that the upgrade test for kde+apt-get hung in the tasksel setup because of dpkg asking conffile questions. No idea why. I worked around it by using 'echo >> /proc/pidofdpkg/fd/0' to tell dpkg to continue. apt-get gnome 72

Also, the list of external (non-mainboard) programmers increases, e.g. there is support for NICs (3COM, Realtek, SMC, others upcoming), SATA/IDE cards from Silicon Image and Highpoint, some NVIDIA cards, and various USB- or parallelport- or serialport- programmers such as the Busirate, Dediprog SF100, FT2232-based SPI programmers and more. More details at flashrom.org and in the list of supported chips, chipsets, baords, and programmers. I uploaded an svn version slightly more recent than 0.9.2 to Debian unstable, which should reach Debian testing (and Ubuntu I guess) soonish.

Wouter Verhelst: Baobab

So, we recorded the performance. As I mentioned in my previous blog post, the sound for sunday was not recorded properly, so while the image looks far better, having a video with no sound is hardly interesting. But as a 'sneak preview' for the people involved, I uploaded one fragment of the Saturday recording to youtube: <object height="385" width="640"><param name="movie" value="http://www.youtube-nocookie.com/v/dziL11aNHvA&amp;fs=1&amp;"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="385" src="http://www.youtube-nocookie.com/v/dziL11aNHvA&amp;fs=1&amp;" type="application/x-shockwave-flash" width="640"></embed></object> There's a lot of grain in this image, courtesy of the fact that two of our three cameras just weren't very good. But beyond that, it looks quite good, I'd say...

Wouter Verhelst: Stuff

I'm running again. No, not running in a bubulle style; I'm running for DPL. It started as a fairly last-minute decision because I would hate to see an election with only one candidate, but then two other people submitted their candidacy right after me. As I stated in my candidacy email, I had "a concert" this weekend. Actually, there were three two-hour performances; two on saturday, one on sunday. Early on, I also suggested videotaping the performance (using the excellent dvswitch, for which I added a patch to support crossfading transitions) to the organising group within the choir, and they liked that. Apart from dvswitch, we used the theatre's own audio mixing setup (so I wouldn't have to worry about that too much) and the theatre's intercom system. I'd made some tally lights, but in the end we were not entirely able to use them, because there were some issues to be dealt with that meant I couldn't quite get them working properly. So on saturday, I was in the theatre pretty early to get everything set up, did some explanations to the volunteers who would do the actual recording, drove my dad (who'd done the direction for the video parts) home, went home, and found my bed at around midnight. On sunday, I got up fairly early, booted my laptop to update the live images with some fixes for some issues we'd encountered on saturday, left for the theatre fairly early again, set up the extra camera position, found out that one of the laptops was actually running at 100Mbit rather than a gigabit and that therefore the extra camera wasn't going to work, learned that one of the volunteers for sunday had done some other camera work for another performance right before that, for which he'd rented some high-end DV-capable cameras. So we broke down the two low-end set-ups, set up the high-end cameras, connected them to the laptops, recalibrated the whitebalance and the diaphragm setting, and restarted the streams. Then one laptop started failing. Since we had had to remove one camera anyway, I just replaced it. By that time, I had about 15 minutes left before sunday's performance would start, so I went to prepare for that. After the performance had finished, I found out that something had gone wrong with the sound of sunday's performance; rather than music, we only heard crackling all the time. Luckily, the sound had also been separately recorded to a different medium, and that recording is fine, so we only need to resync the audio to the video, which should not be a problem. All in all, I had an extremely busy weekend. The alert reader will note that I didn't mention 'food' anywhere in the above paragraphs, mostly because I hardly ever found the time to eat. But it was also extremely satisfying. We still have some postprocessing to do, but I expect I'll put some videos online once we've done that. They're truly stunning, at times. And then yesterday I still had to spend some time writing my DPL platform, and doing some campaigning work. All in all, I didn't find my bed until approximately 4 AM... oh well. I look forward to the election time, and hope that I will do well. I don't need to win, but I'd hope my result will be at least as good as the last time... Update: we used the theatre's audio setup, not video setup -- oops :-)

Joerg Jaspert: Vacation fun

As some people know, I had a vacation in February. Only very few knew that I was heading down to Taiwan. I was leaving Germany at the 8th and back here on the 24th of February. Yes, that neatly fit this years Chinese New Years parties. Was at home for four days (and at work for one), after which I went off to this years Cebit. Until the day I arrived in Taiwan it looked like we do not have a booth there, but then everything changed while I was having a nice vacation. I really have to thank Alex here. Cebit was actually my task, but he jumped in and did all the preparatory work that was needed right in the time I started my vacation. Without that either my vacation would have been much different and less nice or we wouldn t have had a booth. I am back home since some days now, without any travel plans for the next few weeks/months to come. Though I wish I had a job (and private life) that would allow me to just go off again, ie. something I could do everywhere where there is net. Meh. Of course I did take some pictures (more than 2500) and also some notes during the trip. And having a blog that one or two people read, I think I should bore you all with it. But hey, you can skip it if you want. :) Yes, I should really take some time and work a bit on the pictures I took. Right now I only selected around seven hundred which I show off to people (and to link to from here), but they are basically just copies. While some are great in itself, many can need a bit of work here and there (cut out unimportant, blurry, colors, the usual stuff). And I also prepared multiple shots for HDR processing or to make a panorama view from, but thats something that takes time and has to wait. Just for the record, I think that this, this and this are very nice ones.
This is a public version of this text, so names and also various events and days have been cut out. Yes, people who know those in my pictures will know names, but thats no reason to feed the evil $searchengine caches more with hits for their names. Flight down, 8 Feb. Flight down from Frankfurt, using KLM so it went via Amsterdam and Bangkok (short Transit stop) to Taipei. The days before we had lots of snow and cold and all that stuff which tends to get flights cancelled, but I was lucky, none of that for me. The only slightly annoying thing was in Taipei, where KLM demonstrated how much a Business class Priority luggage sign is worth for them sometimes. We came in half an hour before schedule, but then had to wait an hour for our luggage (while all of economy luggage passed by). I think the business class Priority sign actually meant Priority to wait . The food on the flight from AMS to BGK was good, having a No Lactose Meal actually tasting well. Can t remember what it was, but better than the fish I got from BGK to TPE. Catering from Thai Airways, they do not know anything besides Fish when preparing No lactose meal and then they also manage to prepare it in the most boring way possible. Sad thing, but happened four times now, all the times I had catering prepared by them. Other than those points, no trouble at all. Immigration was done in about 20 seconds, customs didn t want to look at me, just the asians in front and behind me, all fine. Met my Travel Companion outside and off we got. First to the Taipei Main Station, where we got some food. Some rice (with a bit of meat) and red sauce, together with a soup. And a glass of tea, but that had an oily surface. Umm. Guess the cup wasn t all that clean, we both skipped that. Then I tried to get money from an ATM. First had to find one that actually wants my european credit card. And then, as usual when I travel offroad, I managed to forget my pin. Bah. Well, found an HSBC somewhere that actually takes my Maestro card, so at some point I got money (a pretty helpful thing, that is).
Wednesday, 10 Feb. First night in a new Timezone which is 7 hours before my normal one. Makes my body think I should not be allowed to sleep much. So it only allowed me some two hours before I woke up again. It didn t listen to any argument and didn t care that it was all dark and night, so I couldn t sleep more. Wellwell, got up at the same time as $TC then, we got some breakfast, egg/ham sandwich and tea. From there I set off and juggled my way through Taipei MRT over to YuanShan Station.
Confucius Temple
It is good for a visit of the Confucius Temple and also the Dalongdong Baoan Temple which is right beside it. Later on I got told there are much more impressive Confucius temples elsewhere, but it is still a good place to start off. And it just means I have one more reason for another visit. After those two temples I moved over to the Taipei Fine Arts Museum. Took about an hour to go through that museum, which again made it pretty clear to me: Some people just have too much time and money. I do not even get the setup in the entry hall, even though it looks nice, and let s not start about the rest they show there. Definitely not my thing, Fine Arts , nothing worth to waste money on, at least for me.
Having fun
So I left there after just about an hour and fought the MRT again. This time it spit me out at the Taipei Zoo station and I went through that. Appearently the nice sunny weather let some animals have fun, and that all in public. Tssk. Won t someone please think of the children?! :) Otherwise it is a pretty big area with lots of animals. Not all of them seem to be in areas that (I think) are big enough for them, though I m no expert in that. But it looked small for them. Also, while I thought it pretty well visited, many people there, I bet for Taiwanese standards the zoo was nearly empty. At least looking at their preparations for queues, like in front of the koala house, they are used to deal with like 20 times the amount of people. I count me lucky that there haven t been that many, else I would have needed to wait everywhere, which I hate. Queues are bad, mmmmmkay? As I already mentioned, the weather that day was pretty nice. Mostly sunny, only few clouds and some 25 til 29 degrees. No rain. Now that s a nice winter day.
HotPot
Dinner was scheduled for 1800h, a Hot Pot session. 5 people in total. Appears you order the meat for the hot pots from the waiter and let them bring it, but all the additional stuff you get yourself. They have a big selection of vegetables, seafood, bread/cake like stuff and whatnot you can take. I first also went there and got a small dish with stuff. But stopped right then and let the Taiwanese do the rest. Better that way, they know it. And hey, we had been 5 and they got stuff for like 35 people. :) It was a nice 2 hour session, in which we had lots of different kinds of additions to the hotpot (two pots actually, one spicy and one not spicy). I know of some meats, some vegetables, but then there also was said to be duck bladder and some other organs which they couldn t (or didn t want to? :) ) name in english. Now, db sounds worse than it is, it doesn t have a special taste and is mostly boring, I think. Of course, not liking seafood, I skipped on that, but about all the rest was nice. I like Hot Pot :) After this session the other 3 left for various reasons and $TC and me had a nice walk around/through the University, before going back to $TCs place.
Thursday, 11 Feb Had another short night as I only got to bed around 2AM, just to get up around 9AM. Additional fun that my body again insisted in being elsewhere, not accustomed to the timezone in Taiwan yet, waking me up a few times during the night.
Fishermans Wharf
Got an easypass for the MRT as that is a little better than buying a chip for every single trip and battled with MRT again, finally emerging at Danshui station. Sat a bit at the beach eating breakfast before finally starting a walk out to the Fisherman s Wharf . It is some 4 kilometers to it, made out as a bicycle path, but I just walked. Visited Fort San Domingo on the way and then went all the way up in that Wharf area, another kilometer. Got me a nice peppermint ice tea, though it was a funny process to it. The salesperson didn t speak english and my chinese is - well, limited is a too soft word to describe it. But it worked pretty well, with us pointing around on the menu and then the salesman showing me various additions, if I would want them. Like showing a milk bottle Want milk in tea? , showing sugar,
Spongebob
At the bridge in that Wharf I was approached by some Asian people, asking me to take a picture of them in front of the bridge. Fine, did it, did it again in another setting and then, when done, they asked me where I am from. When I said Germany they thanked me in German which surprised me a little. :) That is something funny anyways. Wherever I go, people look. They aren t much used to someone my size. Kids are usually more direct with pointing, grinning and sometimes crossing my way on purpose, just saying hi (some kind of test of courage, I bet). Every now and then I also get asked if they can take a picture with me. Right now there are like 20 pictures of me (that I know of) all over Taiwan that I didn t take, nor have. :) Now, who here loves Spongebob? This is the country for you! The picture only shows one small table, you can find much much more. Same goes for Hello Kitty and other such stuff.
Food!
Dinner this day was initially planned to be at some place called Maokong, but then plans changed, as $TC and others that we should meet there needed to pack for the next day. So $TC and me just went to the Shilin Night Market. Right beside it is a big food plaza. Like a thousand square meters (or probably a few more, what do I know, I haven t measured it, but it wasn t all too big) having some hundred or more little kitchens where you can get a very broad mix of things. We had cold noodles with some slightly spicy sauce and then some fresh guava juice. Tasty tasty. Though noodles with chopsticks was something new, but it worked out well enough. Later I had a noodle soup, that was something more tricky, but in the end you just need to find the right trick.
Little crowded
After food we went through the night market. Well. Parts of it. It s big. And its crowded. About the most crowded place I ve been to. Heck, half of Taiwan was in that street area. :) Didn t buy anything. The only stuff I thought interesting was a T-Shirt with a Taiwan map on it, but do try getting some in my size. Ha. Small asians. They say they have big sizes, but then its XL only (or a totally ugly color, brrr). We finished early here, as the packing for the trip starting Friday right in the middle of the night still needed to be done, and getting up at 6AM you do not want to stay up too late. But it was nice there anyways.
Friday, 12 Feb Got up early. I mean, early. 6 AM. ARGS. Not really my favorite thing to do, but as our plan said we have to get the HighSpeedRail to Kaohsiung at 7:42AM there wasn t much else to do. Pretty nice train, lots of room to sit, even in second class. Don t know business, but probably even more. And it looks fast, if I can trust the display it had we where going near 300km/h. After arrival in Kaohsiung we went out to $TC s place to get our luggage away, as it is annoying to move around with all the stuff. I got another easypass here, this time a lent one from $TC s Mother. It s fun, there are two MRT systems in Taiwan using the same technics, basically the one in Kaohsiung is built like the one in Taipei, using the same style of RFID cards (and chips for single trips). But they made them incompatible. One can not use a pass from Taipei in Kaohsiung and vice versa, for whatever reason. It s not like the two cities are very far away from each other, it would actually make sense to be compatible, but that is probably what stops them doing it. We took this Friday and also the Saturday to get around Kaohsiung, visiting several places. As the MRT in Kaohsiung has a different station design at every of its stations we did look at some of those too. Especially Formosa Boulevard , a station that has two points describing it best:
one part of the dome of light
Right outside one of the exits is a funny little cosmetic surgery. I only remember it thanks to the english name of the Doc, but somehow I don t think it was chosen wisely: Dr. Luck . . Aiik, you need be lucky to get out there looking better? Dr. Unlucky might not be good for you taking a wrong cut? :) (Yes, I know, I m crazy, don t tell me. Ok, if you really want, queue up, you aren t the first.) At one point we went out to Sizihwan, where we walked to a ferry. Actually we tried renting bikes, but this little bike shop wasn t prepared for a small german like me, not having bikes my size. (And no safe way to get the saddle of the smaller ones into a height I could start using the bike). So walk it was, not nice bike trip. Still ok, got to the ferry, got over to the other side and had a nice walk there to the/along the coast.
one more temple
We bypassed multiple temples there, at one of which a great cite came up: Temples in Taiwan are something like 7-eleven. They are everywhere. I love it. And somehow it s true, you can find one around each other corner, a little like those churches in Puebla, Mexico. In the evening we had been out for a night market. The first one was pretty boring. While having been announced in the MRT station near it to be a night market for New Years things, we found it to be about empty and very boring, so we went over to another one nearby. Wasn t as crowded as the Shilin one, and not as large, but nice. At the end of it had been a small game stand, where one could shoot balloons to get some price. I ended up getting the biggest available, as this isn t really a challenge. How anyone can miss hitting a balloon there I don t know. They are only like 3m away, not moving, you have clear view, and if you really need it even get a laser pointer on your gun. Anyways, was fun enough, I repeated shooting enough times to get the biggest available Patrick doll they had (a meter). Hrhr. Who likes Spongebob, eh? Speak up! :) I got a few nice shots of the night skyline of Kaohsiung late one of those evenings, where we went to the Dream Mall and up into the big wheel . Also had some game spots there, but turns out I m not as good throwing things at a target than I am shooting at them. We also went out to a historical sugar refinery, looking around. Of course, this being Chinese New Years eve, there haven t been that much people moving around, it was pretty empty. And the people working there all just waiting for their shift to end. But still got some pretty nice pictures from and around it. Also tasted a new kind of icecream (new for me that is), which actually has a kind of sand like feel. I like it. Like I actually liked most of the food, pretty much all the time. Of course everyone has things one does not like, but in general the food is great. Especially the largely different style compared to the european way of cooking. I ate lots of things I won t ever touch here in Germany.
Sunday, 14 Feb; Monday 15 Feb A nice two days some way out of Kaohsiung. Found out I am pretty good at losing various things: I got a bag full of (Li n w ; Syzygium samarangense; wax apple, love apple, java apple, bellfruit, see the wikipedia page for more on it) and about an hour later I totally had lost track where it ended up. The same happened with a big bag of tissues I had bought. Somehow both of the bags got feet and ended up elsewhere without telling me.
ocean place
That one evening we went out for Dinner, a big party of people. Was a place right beside the ocean, so yes, seafood. Oh yay, I don t like that too much. Happy enough there must have been a conversation going on like Hey people, this silly german doesn t like seafood much, lets get one other option too . So we had a plate with some cold chicken on. But I tried various of the seafood dishes too and liked some of them. Actually some I had tried in Germany at some point where I learned to hate them and now I liked them as I got them in Taiwan. People also seemed to think I am good at using chopsticks, though I think I am just fiddling around and be lucky when I get my stuff. But maybe it just means Hey, it looks funny what you are doing. Keep going, we like to laugh. :) ). We actually had been around this place a little earlier that day, taking a walk around it, drinking some tea, that type of thing. And got a set of nice bottles of fresh coconut juice. My first time i got it fresh, I think. But I also managed to lose track of it. I bet somewhere there is a party consisting of tissues, (Li n w ) and a bottle of coconut juice, singing classic songs like Strike, we escaped the german Lunch the other day happened to be a big family meetup. Lots of people, lots of chatting, lots of fun (I think :) ). When we arrived it started out by about all of them trying to get me to sit down somewhere. And me bad impolite german not wanting to. But there was no way to escape, so finally they won and I sat, with a number of people around me, trying to chat with me. Which is actually hard work for both sides, but every now and then gets a good laugh. But my chinese is far far away from being useful for even a small meaningful sentence, so they had to activate their english knowledge, especially for the times $TC had been elsewhere and couldn t help out translating. Somehow the job got done, they asked their questions and I hope they mostly understood my replies. Bad me, speaking too fast english sometimes. We had a nice lunch there, with the most notable part being the way I got called to it. It s interesting how much you can say by just using body language and pointing. (Oh, of course food was very good too, but that fact is one you can take as a given, even if I don t mention it again). Later on a dice game started, and after a short explanation of the rules I joined in. Took only a little, but then I got the rules, its easy. I didn t get any of the chatting that happened during the whole game, but it was very much fun and really insane (so would also fit DebConf very well) and nearly no times you do need words to understand what is going on. I like this game and they gave me a set of dices, so I can train it and come back to play again. Ha. A bit after that dice game people unpacked some of the sweets I brought from Germany. One of them being spicy. Really nicely spicy, at least for the average Taiwanese. If you happen to have been at DebConf9 and also had the luck to be one of those I offered some chocolate or wine gum to, you know what I write about. The stuff here was slightly less spicy, but still more than enough to leave a nice impression. They had lots of - well - fun trying them out, gave a good set of laughter. And ordered more for next time. Uhoh, I already know which I will take with me, but then there have to be special preparations before testing. :) I ve also got invited to come back next year. Might be I haven t made the worst impression. Well, lets see if I can take this up and if they still want me in a years time. At least my chinese should be much better by then, given another year of training. (Even if I find it actually hard to learn. For some reason its not easy for me to memorize language things, at least not chinese. Oh my, one year, I should have some 3 words more, I hope :) ). In the evening, back in Kaohsiung, $TC also told me rules of a second dice game that I had seen some people playing. Also seems like fun if played with enough people.
Tuesday, 16th Feb
35mins delay
We started the trip by taking the train from Kaohsiung to Taitung. We had been a little late for it, had to run from the MRT to the train station. Silly me took that as an opportunity to fall down a set of stairs. Only to discover, when getting to the platform, that the Taiwan Railway wanted to give me a feeling of home, delaying the train. First by 31 minutes, later it got up to 43 minutes. Somehow felt like Deutsche Bahn, being late is also their best quality. When the train finally got in we saw that we had been lucky to have seats reserved, this train was full, lots of people moving around within Taiwan that day. We got to Taitung all fine and had the Hotel send someone to pick us up at the train station, as it is a long way from the train station over to the Hotel. Got our room and left it pretty soon again to look around.
Hello Kitty
Spotted a funny little Hello Kitty car and got some food for lunch followed by a walk along the beach. Found some sculptures made of wood, where one of it seems to have some bad stomach problems
Wooden figure with stomach problems
Later on we had a nice and long walk through Taitung Forest Park. Took some time, got some nice pictures. It was getting dark when we got back into town, time for Dinner already. Yay, food. Next day a train trip to Hualien was set, but only for the afternoon, so we had time to look around. We first went through the Peinan Cultural Park, but unfortunately
Park your dog
we had no dog to park there. After that we rented a scooter to get a little farther away from the train station. After getting some fuel for it we headed to National Museum of Prehistory (which was much more interesting than the Fine Arts one earlier) and later on just drove around some time. Just looking around, without a clear direction, simply for the look around. Was fun, but too short actually. But we had to head back at some point to catch our train over to Hualien. In Hualien we again got a Taxi to the Hotel. We left that soon after arriving, Hotel rooms are boring, and it was food time again anyways. Only a little annoying, one of the few days we had rain and I can imagine something nicer than rain when I am outside. But somehow this damn weather doesn t bother to stop raining when I go out.
Thursday, 18th Feb A full day stay in Hualien, no Hotel change. Just a trip over to the Taroko Gorge.
Taroko Gorge
Which is a very nice and impressive place to visit, sure too much for a single day, I definitely have to come back here. (Well, I have to come back for multiple other reasons, but this sure is one). We took the bus to the first stop in that park, somewhere around the Leader Village Taroko. Probably a nice place for a night or ten.
Nice place?
There was a short trail we followed, getting some more pictures and impressions, but it didn t take us long until we where back in a queue for a bus, this one going all the way up to the furthest away spot a bus goes to. There we had some lunch before we wanted to start walking around. Unfortunately (for my nose) we then passed by a place selling Stinking Tofu . Other customers there said that this is not the best available, but I got a taste of it. Don t really need that version more often, even though its not as bad as it smells or the name suggests. We walked a little there and I got some more pictures before we set off to climb the stairs to the Hsiang-Te Temple of Taroko .
Hsiang-Te Temple of Taroko
Looking down from there we saw a lot of buses which was our sign to get back to the bus station, as the last bus was scheduled to get off somewhere at 3 in the afternoon. And as we didn t have a Hotel place here it is pretty helpful to catch the bus. So we queued up once more and had a bus ride back to the train station. Next time there should definitely be a night or more in some Hotel somewhere there. On the way back we took a slight detour, having another time at the beach, not enjoying the weather which insisted on a little rain and lots of wind.
Friday, 19th Feb This day saw us moving to Luodong, another place with a day of rain. Still, my gps log tells me we where moving around a lot, even though I do not have a single picture from the whole day. And as pictures are the main source of my memory ups. Well, I remember the rain, of course. I also remember that I got a steak at some place and that we bought various kinds of food (and tea and juice! :) ) on one of those markets, eating it in our Hotel room. (Rain is bad, mmmmmmmkay?!). And there was some kind of park too, in which I got a funny little game. Oh well.

Way to go
There is nothing nicer than starting a day with a fun bus trip in the morning. Going high up into the mountains. On a day where the clouds reach down to some level underground, more or less. Using very narrow streets and the usual mountain like narrow curves. While not being able to see far. We got up to Taipingshan all fine but once there we had to wait for our room to be ready. So we took a walk around. Actually not a walk. More a climb. Being a mountain place, and those mountains never having heard of those nice invention called elevator or that other named escalator, people setup stairs. Millions of them.
atmosphere
Besides the stairs it is a very nice place to walk around. We took various of the trails through the area and besides me sometimes nearly falling down (damn slippery grounds) it was great. At some point in the afternoon we got our room and also ate some instant noodles before taking another trail, one that took us some 2 hours. You should really take a look at all the pictures I took, as the few I link directly sure do not present this area right. Taipingshan starts at Picture 434 and continues up to Picture 634, but a good number of them is from the second day too.
Sunday, 21st Feb Contrary to the day before there wasn t a single cloud to spot. Ok, ok, there have been some, pictures proof it, but it was a nice sunny day. Nice start of the end of the trip through Taiwan (still one and a half day in Taipei to follow, but the trip around country is over). Of course that meant taking a lot of pictures again,
a sunny morning
and soon after breakfast we took the BongBong Train over over to the Maosing station. There are again a few prepared trails, most of which we took. We only skipped on the one going to the waterfalls, as it wouldn t have fit into our schedule. Got compensated with a pretty adventurous track with lots of nice sights following the old train tracks. Thanks to a number of landslides there is no train going anymore and thus it is a nice way to walk.
rails
It is a 1500m long walk and sometimes you really have to be careful, but it provides many great views and is a really nice trail. Got a few hundred pictures, yay. Including a proof I ve really been there. I hate pictures with me, really, they are just shit by default (maybe I shouldn t be in them?), but in total I got 11 pictures that proof I was really there and not only sent a camera (four of those are included in that gallery I always link to). We got back to the main place around noon and after Lunch we took the Bus back down to Ylan. The bus was scheduled to go at 15:30h, so we went to it fifteen minutes earlier. While we had a sunny day, clouds had started coming in at 15:00h, and at the time the bus started it was all white and there wasn t much too see for the driver again.
me was there
But it turned out that this makes no difference. The driver must have a very prominent wish to die while taking his passengers with him. Or he is insane. Or has a very important appointment somewhere else. Whatever it is, he drove down, on narrow streets, very tight curves, not too much sight and all that with a speed thats incredible. Several times a part of our bus was out over the abyss. I found it pretty fun and all that, especially as it made for a set of very nice views all over the area, and appearently another passenger thought similar, but $TC did have quite the opposite of thoughts and did not feel all that great. We arrived in Ylan one hour before schedule, which, on a 70km trip through mountain area should give a hint how it was. Took a minute off to regenerate and then we wanted to look around a bit. Having our luggage with us that is annoying so we tried to leave that at the train stations baggage service counter. Turns out the personell there is a bunch of crackmonkeys not following their own advertised opening times. Probably wanted to go home early, those lazy dolts. Fortunately the people at the ticket counter were better and exchanged our tickets and we took the Train back to Taipei a little earlier than initially planned.
Monday, 22nd Feb Bad day for all those people who had a nice vacation during Chinese New Year, they had to get back to work. I didn t have that problem and so went around Taipei a bit. Initially I had plans of going to some tourist spots, like the National Palace Museum or others, but then just skipped them all and just took a walk through various spots of Taipei. Basically just Get out of MRT station XY, walk around . The GPS track later told me that I actually covered about 15 km that way, and my feet agreed to that. At some point I did bypass a German Cuisine restaurant, called Zum Fass . Don t ask me how the food is there, I wasn t in, but still had to grin a little when reading the menu. In the evening we went out to get me some Tea to bring back to Germany. Well, some is some kind of understatement, it was lots, as much as I could pack. But good stuff, some of it is steaming right now right besides the keyboard here. Yummy.
Tuesday, 23rd Feb
lantern
As always, the worst day of any vacation. The day you have to leave and go back home. My flight was scheduled for 20:00h, so I took another half a day just looking around Taipei. Which made me even more jealous of those not having to get away, as I happened to pass by some preparations for the Lantern festival. Which happened only a few days after I got away. Next year I have to plan better and stay longer, what I saw on preparations, and that only at the Sun Yat-sen Memorial Hall definitely makes it worth it. Timing in the afternoon was very tight, I actually got the last bus that was in time for my flight. Just one later would have created some trouble, my total time on the airport was something around 30 minutes before boarding started. Just enough to get the minimum needed amount of postcards written and off to boarding. The flight back was boring. Food from TPE to BGK was a pretty good variation on No lactose , some noodles with stuff. Of course from BGK over to AMS it was fish again, same boring Thai Catering as usual. I was unable to sleep well on the flight. Somehow I woke up very often despite earplugs and eye mask. With all that I turned out to be half asleep when we arrived in Amsterdam and so I accidently took an opened half litre bottle of water with me through security. Funny, they didn t spot it. Instead they decided to make a big fuss about my camera bag, asking me in detail what I have in there, supposedly trying to check if I know what I carry. And made an even bigger show of scanning it again. And that bad liquid that those idiotic stupid laws written by brainless monkeys from our governments forbid got no notice at all. Imagine what I could have done to air safety with it! Oh my. Back in Germany my luggage got out first, so no waiting at all. I passed by work to leave some weight there (Hello boss, want some tea?) and went back home. This was also my first trip where I had a noticable jetlag after coming back. For nearly a week my damn body insisted on being in Taiwans timezone, waking me up at times I should sleep, feeling tired when I should be awake. Tssk. Conclusion of this trip: I will be back in Taiwan for sure. I don t care if you take this as a promise or threat, but I will be back! :)

Christian Perrier: Translations: LOL, but after?

Of course, one would expect me to react to this post. Apparently, from my cumulated experience, joking about funny translations is a very widespread game among german-speaking developers (of course, as everybody knows, us French do translate everissing and no single Frainche DiDi will make such fun abaouttel10n wouhorke, aha). I'd say: more generally widespread among people .who jargonize about computing so often in their daily work that they often forget that not everybody, even in a country where people are as clever about English as German/Austrian/Swiss folks are (we all know that 100% population in these places speak a very perfect English) do understand what "downgrade" means. Seriously, "funny" translations are our (translators) daily nightmare. We hate them because we know people hate us (or make jokes about our work) when they face them. The example taken by Patrick is a nice case as "downgrade" is tricky for all of us. For instance, French translators have chosen "revenir la version pr c dente" as "bring back to former version". This is about the only "right" way to say what's being done ("d grader" is another option but that has a negative connotation). Of course, I often *hear* people (incl. me) say "downgrader" which is an horrible neologism....and of course doesn't say anything to people who are clueless in English. English is, unfortunately, often a very compact language. This is our daily pain. So, as German translation of "to downgrade", what do *you* propose, Patrick? "Downgradieren"? Tricky, eh? Taken from APT for "downgrade": Hint: you can see this with "apt-get source aptitude" and look in po/ for you favorite language. That sounds funny to you? Fine. But as usual in free software, please report.....and patches welcome...

Gunnar Wolf: EDUSOL almost over - Some highlights

Whew! Is it karma or what? What makes me get involved in two horribly complex, two-week-long conferences, year after year? Of course, both (DebConf and EDUSOL) are great fun to be part of, and both have greatly influenced both my skills and interests. Anyway, this is the fifth year we hold EDUSOL. Tomorrow we will bring the two weeks of activities to an end, hold the last two videoconferences, and finally declare it a done deal. I must anticipate the facts and call it a success, as it clearly will be recognized as such. One of the most visible although we insist, not the core activities of the Encounter are the videoconferences. They are certainly among the most complex. And the videoconferences' value is greatly enhanced because, even if they are naturally a synchronous activity (it takes place at a given point in time), they live on after they are held: I do my best effort to publish them as soon as possible (less than one day off), and they are posted to their node, from where comments can continue. This was the reason, i.e., why we decided to move at the last minute tomorrow's conference: Due to a misunderstanding, Beatriz Busaniche (a good friend of ours and a very reknown Argentinian Free Software promotor, from Via Libre) thought her talk would be held today, and we had programmed her for tomorrow. No worries - We held it today, and it is already online for whoever wants to take part :-) So, I don't want to hold this any longer (I will link to the two conferences that I'm still missing from this same entry). Here is the list of (and links to) videoconferences we have held.

As two last notes: Regarding the IRC interaction photos I recently talked about, we did a very kewl thing: Take over 2000 consecutive photos and put them together on a stack. Flip them one at a time. What do you get? But of course A very fun to view and interesting interaction video! We have to hand-update it and it is a bit old right now, but nevertheless, it is very interesting as it is. Finally... I must publicly say I can be quite an asshole. And yes, I know I talked this over privately with the affected people and they hold no grudge against me... But still - yesterday we had an IRC talk about NING Latin American Moodlers, by Luc a Osuna (Venezuela) and Maryel Mendiola (Mexico). One of the points they raised was they were working towards (and promoting) a Moodle certification. And... Yes, I recognize I cannot hear the mention of the certification word without jumping and saying certifications are overrated. Well, but being tired, and not being really thoughtful... I should have known where to stop, where it was enough of a point made. I ended up making Maryel and Luc a feel attacked during their own presentation, and that should have never happened. A public and heartfelt apology to them :-(

Gunnar Wolf: Getting closer to the fifth EDUSOL Encounter

This is the fifth year we hold an EDUSOL, and we are closing in on it. EDUSOL is an online encounter whose topics are Education and Free Software Actually, this year we are widening our scope, and we will include Free Culture as well as a base area. Now, besides those three general areas, each year we have had a base topic around which we invite the speakers to talk about (although it is a lax requirement). This year, the base topic is social networks No, not in the Twitter/Facebook/blah sense, but as a wider phenomenon, studying interaction between people, the forming of communities. And for our particular areas, the forming of knowledge-based communities. Anyway I agreed with the organizers to provide the English translation of the participation invitation. I will skip the call for papers, as we are basically at the proposal deadline (October 17), but if you have anything you want to propose, please tell us so! Leaving that aside... Please excuse the quality of my translation, it is late and I'm tired. We will work on it :) Videoconference reception EDUSOL spans several participation categories. The closest category to a traditional, face to face conference. Each year, we invite a group of speakers to talk about a topic related to our main discoursive line. Among the speakers that have confirmed so far, we have: We invite you to be active participants in the videoconference cycle. You can invite your social or user group to be part of the Encounter. There are three ways to do it:
  1. Using the videoconference facilities in your University network
  2. Connecting from a personal computer with broadband access, by using Ekiga or any other H.323 client
  3. Following the .ogg stream and participating back via IRC
In any case (specially in the first two, which require more coordination), please contact us. For further information, visit http://edusol.info/es/e2009/convocatorias/videoconfrencias November 6: Free Education and Free Culture day We invite social and user groups to host talks regarding Free Education and Free Culture. This is not a call to promote Free Software, as there are many other spaces devoted to it. We should start with the idea that freedom resides in us, not in the software. Some of the topics our community recommends are: Further details at http://edusol.info/es/e2009/convocatorias/dialternativo We need some help in this area to generate contents with slides, making it easier for proposed scripts for the talks. If you want to collaborate, please write to our academic support list, http://lists.edusol.info/listinfo.cgi/soporte-academico-edusol.info Want to collaborate? Further questions or comments? We are holding on-line meetings for this group of topics on Thursday 22:00 GMT-5, in the #edusol channel in OFTC (irc.debian.org); you can enter the IRC channel using the Web client at http://irc.bine.org.mx or http://edusol.info/irc About EDUSOL EDUSOL started as a proposal seeking to provide a space so that people interested in education could discuss and analize the good and bad points about Free Culture and Free Software, with no geographic restrictions. Year after year, freedom-loving educators of all Latin America and Spain gather for our annual party. EDUSOL's core language is Spanish, although participation in English is allowed and encouraged (although understanding Spanish will be a strong aid). We invite you to participate and contribute in this collective effort using and commenting on our blogs, or adding your personal blog to our planet: http://edusol.info/es/node/add/blog

Steve McIntyre: Silly photos from Spain

While driving through Spain around DebConf, I saw a few things that I thought I should share with the world... San Sebastian runs on dbus!
let's all take the d-bus! ALSA on a coach:
alsa-riffic Wonderful fuel economy! We managed to fill up with diesel, then coast for about 15 miles down a very very very long downhill stretch into Bilbao. And just before we stopped at a toll booth at the bottom of the hill, the car's estimated MPG figure flipped to 99.9 and we got a blurry photo.
we could drive home on that tank...

Steve McIntyre: Cool DebConf

Yeah, OK, I suck and I should have posted about DebConf 9 while I was there or shortly afterwards. Well, I've been busy with various things (or, to be more specific, one person \o/). I'm slowly catching up on stuff now, so I thought I'd write something and link to some photos! I drove down from the UK with Neil, Chris and Chris and we had a good trip. We left Cambridge really early on Wednesday the 22nd, stopped at Le Mans for lunch, then headed to San Sebastian overnight. The French autoroutes were mostly empty and we made very good time, swapping drivers every two hours. Le Mans The venue was superb, with just about all the facilities we needed on site. And there was a handy outdoor bar in the park just up the street. Yay! MT residence As always, it was excellent to meet up with Debian friends old and new from all over the world. The DebConf team did a great job of making the conference happen and I had a wonderful time, as did everybody else I spoke to. Tincho! There was an official day trip involved, but as we had 2 cars from the UK a group of us rebelled and made our own trip out to do touristy things. We visited the Roman ruins in Merida (photos here), then as we were so close to Portugal we decided to head over the border and found the lovely old town of Elvas. Elvas After the conference, we headed slowly back up to the north coast of Spain, stopping over in Madrid and then Bilbao before catching the overnight ferry back to England. Along the way on that trip we saw a few sights such as the historic city of Pamplona and the "Valley of the Fallen", the monument to people killed in the Spanish Civil War. Valley of the Fallen I got back to Cambridge late on Monday the 3rd, tired but happy. We'd done 2,400 or so miles in the car and several hundred more on the ferry, and we'd all had a great journey. We saw some silly stuff along the way too, and I'll post more about those soon.

Michael Prokop: Debian GNU/Linux 5.0 codename Lenny - News for sysadmins

Alright, Debian GNU/Linux 5.0 AKA as Lenny has been released. Time for a Debian unstable unfreeze party! 8-) What does the new stable release bring for system administrators? I ll give an overview what news you might expect when upgrading from Debian GNU/Linux 4.0, codename Etch (released on 8th April 2007) to the current version Debian GNU/Linux 5.0, codename Lenny (released on 14th February 2009). I try to avoid duplicated information so make sure to read the release announcement and the official release notes for Lenny beforehand. Noteworthy Changes Virtualisation Virtualisation related new tools: Desktop oriented packages like virtualbox and qemu are available as well of course. Noteworthy Updates This is a (selective) list of some noteworthy updates: New packages Lenny ships over 7000 new packages. Lists of new/removed/replaced packages are available online. I ll name 238 sysadmin related packages that might be worth a look. (Note: I don t list addon stuff like optional server-modules, docs-only and kernel-source related packages. I plan to present some of the following packages in more detail in separate blog entries.) Further Ressources

Wouter Verhelst: SSL "telnet"

A common way to debug a network server is to use 'telnet' or 'nc' to connect to the server and issue some commands in the protocol to verify whether everything is working correctly. That obviously only works for ASCII protocols (as opposed to binary protocols), and it obviously also only works if you're not using any encryption. But that doesn't mean you can't test an encrypted protocol in a similar way, thanks to openssl's s_client:

Pierre Machard: Install Debian on Dell Vostro200

Recently, at work we changed our desktop computers. I’ve been faced to difficulties with a Dell Vostro200. Vostro had no OS. The hardware is still very recent. After 2 days I finally succeed in it. : The content of my box : (lspci and lspci -v).

So let me explain how I did.
  1. First, I used a netboot. I downloaded a recent netboot.tar.gz (from Debian website). I downloaded a daily image and use a Netboot PXE.. Not all the netboot.tar.gz are working… (That is to say, that I am not sure that all daily snapshot are working). I used this tarball:
    http://migus.nerim.net/vostro200/netboot.tar.gz
    I tried to build my own netboot.tar.gz without success. IRQ conflicts always vanished the debian-installer. I wish I had included the lastest e1000 drivers in my netboot…
  2. I had a problem of network hardware (Intel e1000 included in vostro 200 is too recent). So
  3. I decided to plug the time of my install an old 10OMb/s Ethernet card (e100 with PXE).
  4. Very quickly I had IRQ conflicts that blocked the disk detection. (SATA Controller had timeout).
  5. I passed the following arguments to the install command line acpi=off  irqpoll  vga=791
  6. Everything went well. The installer finished its work. The box rebooted.
  7. I downloaded module assistant, kernel-headers, gcc : aptitude install module-assistant gcc linux-headers-2.6.21-2
    and the e1000 driver from http://sourceforge.net/projects/e1000/. I just run make install
  8. (for lspci I ran a update-pciids (8)).
Everyting work well since :-) Conclusion :
1) Install an old PCI Ethernet card with PXE
2) Install DHCP + PXE
2a) Find a netboot.tar.gz that work without freeze. (the tarball on my website works)
2b)Do not forget to plug your USB keyboard in the usb connector just bellow your ethernet connector. (If you don’t for an unknown reason, when you type on a key, Your box get it twice….)
3) Tune the installer command line : acpi=off  irqpoll
[let’s the installer worked]
4) Download e1000 driver
5) Remove your old PCI Ethernet Card.
6) Be happy
6a)If you want to enable acpi into your desktop, once you installed your system you can try acpi=noirq irqpoll.

Neil Williams: dpkg filtering

This started as an Emdebian idea but it is growing into a more all-purpose option. The requirement is to be able to filter packages during installation or cross-building so that manpages, infopages, documentation (including changelogs, copyright and readme etc.) and translation files for unsupported locales are omitted. When installing, the files would simply not appear on the filesystem or in the dpkg status information. When building, the files would disappear from the package completely (hence the role of filtering in Emdebian). The intention is that embedded systems can have empty /usr/share/man/ /usr/share/info/ and /usr/share/doc directories and a much reduced number of translation files in /usr/share/locale - the default would be only the translation files for languages that are supported on that machine, via 'dpkg-reconfigure locales'. Initially, only the narrow filters needed by Emdebian were considered - discussions at DebConf7 have shown how this can be easily extended to support arbitrary filters - necessarily the risks of using such optional filters would be made clear to the users in the manpage etc. - so that any file in any package could be omitted from the install process and the package file lists as well as during the preparation of packages for embedded devices.

Filters would be glob patterns held in a file in /etc/ (possibly /etc/dpkg/filters.d/) and would include the option to exclude files en-masse and specifically include some files that may otherwise be excluded in specific circumstances. The same filters could be used when building packages for embedded usage as well as installing Debian packages on systems where space is a problem. The main benefit of this filtering for Emdebian is that it makes it much easier to isolate the package changes needed to make the package cross-compilable from the changes needed to remove stuff that embedded devices don't need but which Debian Policy requires. This in turn makes Emdebian patches more useful to Debian maintainers when bugs are filed on their packages about a failed cross-build.

So far, it's taken up most of my hacking time in DebConf. Ian Jackson, Enrico Zini and Wookey have all helped improve the original ideas during that time. Prototype code is mostly complete but the extended filtering support will now have to wait until after DebConf. I'm hopeful that the patch will be accepted, once it is ready.

If this seems strange or unnecessary, just compare the disc usage of /usr/share/doc (which you can control) with /usr/share/locale/ (which you cannot currently control) or view the baobab images from my current laptop installation.
