Besides an unbelievable ammount of unripe berries we did encounter too many mosquitoes (not bugs and luckily no sand-flies), yet found free-wifi in the most unexpected spots under the midnight sun.blog:breedr2008-10-06T11:34:13+00:002008-10-06T11:34:13+00:00http://mir.dnsalias.com/blog/breedr?rev=1223292853I'm just recovering from the picnicnetwork.org conference where I forged some new contacts and renewed many old.
The week before picnic we had the chance to build and design interactive installations presented at the conference in a 5 day hackers-camp. We rented a house with 30 people and as you can imagine there was little time for sleep. Besides supporting the camp on oAuth and anyMeta.

Frontera is a touch-screen that projects a pre-recorded video of a player touching the screen at the same position as the user. I'm going to do the whole installation (hand-detection, recording and playback) from-scratch together with Arjan Scherpenisse. the sources will be on sourceforge. - stay tuned.blog:liboauth_0.3.02008-08-25T03:53:38+00:002008-08-25T03:53:38+00:00http://mir.dnsalias.com/blog/liboauth_0.3.0?rev=1219636418Yet another Sunday without sun in Amsterdam... I spent the afternoon fixing an
issue with empty URL paths
for liboauth.
After scraping the documentation I choose to
insert a slash before the [first] '?' (or '&' or end of string) if and only if
there is no '/' between the protocol's /:\/[\/]*/ and the delimiter.
It looks like a dirty hack, but checking the BNF this seems perfectly ok. All slashes in the /authority/-part of the URL (userinfo, host) should have been escaped. This was too easy an…blog:linux_film_browsing2009-01-01T16:06:25+00:002009-01-01T16:06:25+00:00http://mir.dnsalias.com/blog/linux_film_browsing?rev=1230825985Happy new 1984 2009! Neujahr what a great day to update the blog.
I spent the quiet days unwrapping the web-interface of the sodankyla film server; adding an audio-decoder and streaming capability. Quite a cool gift for media archivers. It's the last piece of infrastructure before work on the compositor and session management can begin. I've attached a few screenshots of the bare-bone interface: seeking to frames and streaming/exporting an excerpt.blog:linux_sound_tags2008-08-11T02:28:20+00:002008-08-11T02:28:20+00:00http://mir.dnsalias.com/blog/linux_sound_tags?rev=1218421700Categorizing linux audio applications
As a first step to clean up the tag mess at <http://apps.linuxaudio.org> I started to visualize “the problem”.
It turns out there are ~1800 tagged pages with ~200 unique tags.
Most of the tags go back to headlines in the original data of linux-sound.org. All applicable headings (<h1>..<h5> and <li><b>..) were used as tags for a given link in a flat structure. However interrelations between the tags (headings) have been maintained by tagging the tags thems…blog:linuxaudio.org2008-08-09T20:31:40+00:002008-08-09T20:31:40+00:00http://mir.dnsalias.com/blog/linuxaudio.org?rev=1218313900..so what have you done on 8/8/8 ?
I spent the morning reading <http://dyne.org/first_dharma_dyne.pdf>
and been hanging out at Nadya's good by party: Lucky girls attend MIT in roaring 1920 style.
Much of my time the last days went into linuxaudio.org and related endeavors: On the WWW front I set up a public git repository (using gitosis, gitweb and git-daemon) running on <http://git.linuxaudio.org/> , updated the dokuwiki at <http://apps.linuxaudio.org/> and for good measure threw in an ABC-M…blog:osxjadeo2008-12-17T18:22:03+00:002008-12-17T18:22:03+00:00http://mir.dnsalias.com/blog/osxjadeo?rev=1229538123I've just completed the first round of porting xjadeo to OSX.
On the way to learn about cross-OS video coding and prepare for sodankyla, I've added a native display (carbon/quicktime) and included a mac-style menu-bar to Jadeo instead of using remote-control and qjadeo. Far from perfect but usable, there's still performance improvements on the ToDo-list and surely a bug or two to fix ;)blog:picnic082008-09-21T22:54:56+00:002008-09-21T22:54:56+00:00http://mir.dnsalias.com/blog/picnic08?rev=1222037696Since Friday I'm hacking almost non-stop for the picnic conference where registered conference visitors keep their online-profile on a RFID-chip (ik-tag or i-tag) which they can use to sign up for workshops, participate in games, make friends/exchange contacts, get consumption vouchers, etc. throughout the conference.blog:rt2460_and_linux_2.6.312009-09-18T11:09:36+00:002009-09-18T11:09:36+00:00http://mir.dnsalias.com/blog/rt2460_and_linux_2.6.31?rev=1253272176As of linux 2.6.31 there is no mainline support for the Ralink rt2680 Wifi chipset.
While there is an official driver provided by Ralinktech, it is incompatible with 2.6.31 due to the fact that post 2.6.29 the kernel's net_device_ops API has changed and 2.6.31 also removed CONFIG_COMPAT_NET_DEV_OPS backwards compatibility.blog:slowlin2008-10-06T11:38:14+00:002008-10-06T11:38:14+00:00http://mir.dnsalias.com/blog/slowlin?rev=1223293094Berlin is slow, very slow but steady... I had two great weeks of creative holiday, visiting friends & collaborative coders; been hanging out online in the Görlitzer park and read «Robinson Crusoe» during never-ending subway trips.
Most of the Prenzlauer Berg has been taken over by pay-wifi providers, not to mention the tourist commerce. Yet I found the Schleussenkrug in the Tiergarten to be a very comfy place for breakfast and reading email in the sun.

However the latest version (as of writing 0.40) does not work with a real-time patched Linux-kernel.
The problem is that rt-linux uses a new mechanism for mutex-locking, which allows preemption and is incompatible with current Linux-mainline. In order to get the tp_smapi driver compile with rt-linux you need to replace the MUTEX locks. I came up with a simple patch that applies to tp_s…blog:unusual_workflow2008-12-17T18:20:23+00:002008-12-17T18:20:23+00:00http://mir.dnsalias.com/blog/unusual_workflow?rev=1229538023It's been almost two months since the last post which I mostly spent pushing open-source tools to the limit with film-postproduction.
Looking at the rushed scans for the Wicked offline-edit, I noticed that some sound-clips have gone missing and only the 16 bit versions of the audio have been synced to the new-timecode. No EDL has been provided by Filmmore either. dang.blog:wicked_days2008-12-17T18:22:45+00:002008-12-17T18:22:45+00:00http://mir.dnsalias.com/blog/wicked_days?rev=1229538165I spent the last days on the Wicked film set; driving the Chevrolet Impala set-car in gorgeous weather with an amazing team in the Amsterdamse Bos. Thanks everyone! Before post-production (and sodankyla development) begins I'm just about to release oauth-utils, preparing for the dokuwiki oAuth plug-in. Oh, a film-website is also on my ToDo list, besides ..well you don't wanna know.

So here's a few more updates before x-mas. I'm thinking of attending 25c3 and to check out the dokuwiki developer room there. After all kind of Audio/Video coding I think I need a break and write some different languages before heading to FOMS and LCA mid Jan 2009.
