BeGeistert 021 Report - October 17 to 18, 2009 Düsseldorf (Germany)

Article by DaaT - 26 October 2009 - IsComputerOn

First of all, sorry for taking so long to post this. Been a busy week but I must admit to lazyness as well. Guilty as charged. As usual, BeGeistert was great and I'm not saying that just for the sheep, honest. Click below for a (not that detailed) report.

This time I didn't go alone, my girlfriend went with me, for a geek-filled weekend... there were 3 couples at BG actually, a record I believe :)

BeGeistert for us started on Friday and didn't start that well. We arrived without a problem at the Dusseldorf airport, problem is, our luggage didn't. Second problem, it was quite cold, around 7C and my warm, nice jacket? In the luggage... So after we arrived at the Hostel, Charlie kindly lent me his jacket and we went shopping for some essentials, jacket included. At night there were around 17 of us there already so we went for dinner at this very nice restaurant, not far from the hostel. Everyone had a good time and the food was delicious, what more can you ask for? During the dinner our luggage was delivered to the hostel, so all's well that ends well. By the way, Jonas from Sweden also had his luggage lost during his trip to Dusseldorf, sheeesh...

Saturday started with the "Auckland Presentation" (which I didn't attend from the start, regretfully), named as such because it was done remotely from New Zealand. The presentation was done by Christof Lutteroth and the subject was ALM, the Auckland Layout Model. The bit I did see was about HaikuHelp, a way to automatically generate help information by "analyzing input messages and state changes in a GUI". It was very interesting and it could be a nice addition to Haiku.

After lunch the French group (which arrived around 6am after driving all night) took over and we had presentations by Maxime Simon on his Google Summer of Code project, the webkit port, and Adrien Destugues gave a presentation on his GSoC project, the locale kit. Maxime didn't have any slides, so his presentation was more of a Q&A session about his and Ryan's work. They're making progress but the webkit project moves so fast they wouldn't mind help from coders wanting to dip in.

Adrien's project is progressing quite well and is now integrated into the Haiku source (happened sometime after the Alpha release). According to Adrien some of the work still needed is, among others, to convert apps to use the locale kit and also a font overlay for japanese characters for example.


After the presentations some of the devs (with a little coaxing from Charlie) got up and the last 6 months of Haiku were discussed. The Summer coding spring at Axel's and of course the Alpha release were the highlights. It was then time for a little celebration, to celebrate Haiku, the Alpha release and all of the devs working on the project. It was a very nice moment of which we posted a photo during that same night as I'm sure you recall.

Saturday night there was a big group dinner which... we missed. Charlie and the gang (could be a band name) left and left the two of us plus Rene Gollent and his girlfriend back at the hostel. The four of us ended up at an Italian restaurant with HUGE coke glasses (their grosse cola really was grosse) and delicious pizza, along with nice live music, jazz. On the way back to the hostel we took a taxi and it was a fun ride since the driver, a turkish guy, spoke portuguese!

Sunday rolled around and in the morning there was a presentation done by Nicholas Blachford (over who's Canon I drooled on Friday, it's a 5D MKII) on Haiku Distro Guidelines. This brought on an interesting debate on the subject with many sharing their point of view.


In the afternoon it was time for Colin Gunther's presentation on bringing WLAN to Haiku. It turns out there are more drivers than the Atheros one that Colin's working on, including the Intel 2200BG (the one I have, yay). In the next 6 months or so he intends on porting over from BSD more drivers, an enhanced ifconfig and have repository integration. Before R1 is out a GUI for WLAN will need to be done as well. In the next 12 months Colin is aiming at encryption and ad-hoc support. (Sunday morning I had a nice chat with Colin and am anxiously waiting for an e-mail with a certain driver to test)


Sunday afteroon was also time for a "class" on coding for Haiku which was held in another room (smaller one, next to the main room) held by Stephan and Jan. Though Stephan tried to lure me in (sorry Stephan :)) I didn't attend, coding isn't for me. But from what we heard it was definitely interesting. In fact, Charlie had the idea to, beginning with next BeGeistert, have an extra Tutorial Day.

I should say that the room was packed! A lot of people attending BeGeistert including all presentations, except Colin's since several people had to leave for home after lunch. Also noteworthy was Rudolf Cornelissen's presence back at BG. It was great to see him again after several years and we had a very nice chat.

All too soon Sunday was over, after another group dinner at yet another Italian restaurant (following a brief passage at a brewery) and it was time to hit the sack, Monday morning we had to get up at 5am for our plane, but there were several people still up, talking and coding, coding and talking, including the devs staying for the coding sprint.

As always BeGeistert was great fun and this time it was special due to the recent Alpha release. You could sense the excitement in the air and the fact that it was crowded didn't hurt either. Even if I won't be able to go, the next BeGeistert can't come soon enough. And mark your calendars, BeGeistert 022 "Return of the Cola Coder" (talk about pressure) will be held over the April 10th-11th weekend and... a tutorial day will be premiered on Monday the 12th! Start boooking your flights.

I can't end this report without one very special mention to Charlie. He's not the only one involved in organizing and hosting BeGeistert of course but he's the "face" of it. His diligency and attention to everyone and everything make BeGeistert for us attending, a pleasure. Charlie, you should have had a glass as well on Saturday :) And the invitation we made still stands of course. Till next time.

Obligatory BeGeistert Report - October 17 to 18, 2009 Düsseldorf (Germany)

Article by mmu_man - 27 October 2009 -

I'm in the TGV back to Valence on wednesday, which luckily has many power plugs, unlike the Thalys which has wifi but no plug for those battery-drained guys like me. It's 21:30 as I start writing this. Will take some more days to finish though...

Not there yet

But first things first, after attending a meeting on Friday in Grenoble, I headed back to Valence to leave some stuff there, then back to the train station, where my train got delayed by an hour or so. But the other frenchies I was to share a car with were also a bit late, so they didn't have to wait for me too much. We then took the road to Düsseldorf and started to talk about each others work, and GSoC since we had two of the students on board.

On a night like this...

After a long digression about the evilness of Flash™ and non-websites, we talked about the state of the localization project, its integration into all applications and the need to pair it with the layout API, and the progress of the Webkit port. Interestingly, Webkit itself has a plugin-based framework for image loading, quite like our Translation Kit, but possibly even more powerful, so there were concerns about either bypassing it to the Translation Kit, or making a Translation Kit plugin as fall-back, or just leave it alone. Probably we can take ideas out of it to improve our Translation Kit. Then the two at the back of the car snooze a bit (guess where I was), while the drivers hopefully didn't.

When we arrived at 6 am, we registered at the office and got some keys, but when we entered the room we disturbed some asleep girls, so we quietly backed up and gave the keys back. We tried other keys but also found long blond hair in the beds, so we decided to just have a sit until the sunrise. We talked about FTTH and geopolitical topics for a change.


We enjoyed a nice german breakfast and headed for the room. Most of the attendees arrived during the morning, and by noon all the seats of the room were taken. René (aka Deadyak) couldn't bring his BeBox this time, but he brought himself which was really nice cause I didn't see him in a while. So did some others who were enticed by the alpha release into getting back on the BeGeistert experience, like Jonas, or Daniel (DaaT) who likely missed watching the sheeps from the river shore! Frenchies were quite present, and Italians as well.

I took my antique IBM model M keyboard out of the bag and aligned it with all the Kinesis ones on the tables, which made for an interesting comparison.

The French team started to look at an issue with the marvell_yukon driver which only worked for a few hundred kB before halting transfers. We tried to eliminate possible IRQ sharing bugs from other drivers, but the problems was still present without other drivers hooked up.

Santa Claus was here in disguise, and handed me a nice black and green box, containing a Neo FreeRunner as another incentive to the ARM port... He also had a new card for Rudolf to play with. Quite early he was this year ;-)

Then I took upon myself to fix the ARM and 68k builds, after Axel's breakage two days before. Others continued to commit fixes and other cleanups.

Despite being on the other side of earth, Christof Lutteroth managed to do a remote presentation of the Auckland Layout Model. I must admit I got lost near the end due to lack of sleep, but luckily the PDF of the presentation is available, and even some sample code.

Maxime detailed his GSoC work on the Webkit port and asked for more hands, and Adrien talked about what he did on the Locale Kit as part of GSoC which is already in svn. Both wore the blue t-shirt for this year's edition, while I left mine for Sunday and instead had the white shirt from the Haikuware Thank You Award. I didn't talk about the ARM port, as I didn't have much more to show than what was already published, but likely next time I'll have more for your eyes.

Then Charlie required an update on the work done since the last BeGeistert, which of course included the alpha release, for which I brought a bottle of Clairette de Die to celebrate, so we opened it and filled some glasses, not everyone had one, but at least it made a nice picture.

Since I also brought a cold with me (it's starting to be a tradition, really), and I wanted to get some work done, I went downstairs with Marcus and ordered a pizza at the bar, which wasn't too bad. Most others went out for dinner. We pondered about watching a movie but as always work took over.


Nicholas had an extensive talk about the so-called "distro guidelines" which not everyone agreed on the definition and targets. Maybe the word "distro" should be avoided, as it actually implies we'd favor distros, while it's not the will of most developers.

Then Colin used rather unusual support for his talk on the wifi stack, which despite a dubious choice for implementation (Flash...) is an interesting concept. As he explained, he has ported wifi stack from BSD, but has to design an object oriented one as part of his master thesis, so it's not the definitive one yet. The current focus for development was to get more drivers integrated.

Stephan and Jan gave a C++ introduction tutorial, I didn't attend but it seems to have been very much appreciated as the proposed tutorial day for next edition is already fully booked. Meanwhile there were some more build breakage to fix.

We moved to a smaller room after everyone else left. Alexandre arrived just in time for the distro talk, which lasted several hours, some of us swapping in and out to do other stuff, and kinda reflected the profusion of thoughs that appeared on the mailing list. We wrote down the list of features we wanted from a package manager, to get the ball rolling.

Meanwhile I fixed the BeOS port of XEmacs with the current source tree from mercurial, and managed to build and run it from Haiku, which was a first since the BeOS binary doesn't run due to the brain dead "unexec/dump" thing of the build process, which involves starting a first binary to load a bunch of lisp files, and dump the resulting process to a cache file to speed up normal runs, which of course hardcodes pointers to stuff, which on Haiku ends up pointing into kernel space since the kernel/user split was reversed back from BeOS R5. It still has some issues, which are not present on ZETA, so likely shows bugs in the Haiku App and Interface Kits.


On Monday I started running svn cleanup on my laptop, because after deciding to svn switch my BFS-hosted source tree to the new server, and trying it from the recently installed Haiku R1/alpha, I spent 4 hours waiting for it do finish silently converting the working copy to the new format which of course isn't readable from ZETA anymore, and then an svn up crashed in the middle. So I spent some more hours running this to remove all locks in the local copy. Then I tried to svn up again, which crashes again. It seems the recent svn:keyword issues had put my local copy in a really strange state...

Oliver eventually put an end to the svn:keywords issue on the repository.

I continued my svn up loops, but also started checking out some stuff to port, like the pciutils (Linux' lspci) which isn't very useful to most of us since we have listdev but can still help driver writers by providing more informations. I extracted a test code from the XEmacs port to pinpoint a deadlock in BApplication::Quit() when the object is not Run() from the main thread.

Another project I worked on this week was IM Kit. After fixing the ZETA build, I still had issues trying to get newly created accounts for the various protocols to be saved and used, I decided to try and build from Haiku. Apart the yahoo add-on all built, with some help, and I even managed to get it to connect and talk to Bruno (BGA) via gtalk. It seems my commits cought attention of the other devs on the projects who committed new code as well.


Oliver who was sitting next to me worked on the BTextView display code to fix wrapping and other glitches. Stephan continued his Media Kit and MediaPlayer fixes and enhancements, trying to get 5.1 audio played, while Axel and Michael chased bugs without mercy.

I committed some new shortcuts to go along the Ctrl-Alt-arrows taken from the Gnome desktop, that is the same ones with Shift held would also move the window to the workspace it's switching to, and fixed some shortcut issues on VNCViewer but it would still need attention. Talking about windows, we also had to play with the automated blinds of the room that kept on rising or descending randomly, to keep it from cutting us from the outside light.

I also kept up on checking out new stuff to port, like fish or xpilot (which I did port to BONE long ago but it still required X11), though most missed some stuff from autofools, er hmm, autotools (like SDL aclocal macros). I also looked at the libusb port I never finished, and it seems the newer version was rewritten from scratch, hopefully more portable, but it seems it will require some more support from the usb_raw driver to handle asynchronous requests.

During the week we also got some screenshots of the upcoming Qt port, which seems quite advanced already.


I continued to svn up and svn cleanup intermittently, trying to update only parts to make the cleanup faster... hopefully I'll get a full checkout someday to build a newer version.

It was also discussed and unanimously voted that Brecht would be granted commit access, also because he was present at the sprint. His first commit raised some warnings from the coding style police, but well, who doesn't get some ?
≶irc>/me hides...</irc>

Since I did many source checkouts those two days, I decided I would make it more user friendly, so I wrote a small application to do exactly this, which handles the git: and soon svn: urls in hyperlinks from your web browser, opens a file panel to ask where you want it, runs the SCM client in a Terminal, and opens the result in Tracker. Check it out ;-)

By the way, it was even my first commit from Haiku!

I had to leave after lunch to get my train, and despite Oliver lending me 20 cents I still missed 10 cents for the tram so had to walk a bit to the next cash dispenser. I eventually made it, and played with the FreeRunner which had more battery than my laptop, and I even managed to crash the session. ;-)

As I noticed, there were many commits from Germany the next days from the others, so I suppose they were still having fun.

This was a very exciting event as always, and even more because of all the known faces reappearing, and the new ones of course. I heard the next edition is nicknamed "The return of the Cola-Coder", who indeed was missed this time, likely it will be interesting too. I didn't do all I had on my list as always, but now I even have more to add to it! I also need to prepare for the upcoming Alchimie 2k9, where I will be showing up the R1/alpha features (but not the bugs hopefully). Also, the booth registration for FOSDEM are now open, so if you feel like helping in February don't hesitate to tell!
