'sup Doc?

It's been a long time coming,…

I have recently defended my doctoral Dissertation (PDF) on The Ardour DAW – Latency Compensation and Anywhere-to-Anywhere Signal Routing Systems at the University Paris 8.

Many thanks for everyone who helped make this happen, friends close and far and all the wonderful people who joined me during various periods along the road in the last 5 years. It's been quite a ride! Dr. Robin

Since 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.

Besides being back coding for mediamatic's anyMeta CMS (here: Community Managemet System), I've teamed up with Luis, Sly, Thijs and Neil to build The Breeder: an installation where you can interact with a virtual creature that «lives on your RFID tag».

Besides feeding the creature with input from your personal-profile and online activity, you can meet with your and other creatures for reproduction at a pond-like portal (beamer, pond with white sand, camera, rfid-readers) that will be exhibited during the conference staring next Wednesday. The Breeder will visualize meta-activity of conference-visitors in a game like environment (processing/java) where creatures can reproduce when their owners meet and recombine genes of their profiles. Furthermore interaction is not limited to the pond: Users can download a screenshot/snapshot of their pet or enter a communication that their creatures stroke up.. - I'm out to walk my amoeba.

It's a very ambitious project, even more so given a 5 days timeframe from idea until deadline.. You can follow development at our project trac/wiki.

linux sound tags

Categorizing linux audio applications

As a first step to clean up the tag mess at I started to visualize “the problem”. It turns out there are ~1800 tagged pages with ~200 unique tags1).

Most of the tags go back to headlines in the original data of 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 themselves. 57 of the 203 tags are not tagged (orphaned, loose), these are either top-level-tags or new additions that have not yet been categorized. An index of all tags can be generarated at; a text-file is available with the sources below.

The most commonly used tags are:

  154 software_sound_synthesis_and_music_composition_packages
  145 other_documentation_and_newsworthy_items
  137 all_things_jack
  119 midi_software
  115 linux_audio_tools
  113 tools_to_make_tools
  110 signal_analysis_processing_software
  102 on-line_articles


I trashed the initial intention to reduce the number of tags to a manageable amount. On the contrary: some of the multi_word_tags shall be broken up, and the overall conclusion is: We just need a better user-interface to browse and assign tags.

dokubookmark already prototypes a check-box interface to manage tags. For the apps-wiki a tag-cloud or hierarchical display would be needed to ultimately improve usability.

More discoveries

Now made visible, I discovered a bug in the tag-inheritance parser which imported the data from linux-sound to the apps-wiki. There are additional false tags to content where a sub-level heading was not closed. Most prominently affected are SOAL and openAL.

I'm pondering on a re-import of the data but that would require magic to merge the updates. Magic is the cue, so I'm now writing a perl-script to manage, rename and clean up the tags:

Source image of all tags (1.8MB)

The data was generated from the wiki-content (dokuwiki text files) using this greppy shell-script and graphviz. The png/jpeg images turned out to be rather large (2400×2200 pixel ~2MB). I suggest you download look at the SVG or render images from source.


The color of each tag gives a hint on how often it is used. This value is also printed in brackets after each tag-name. red color increases with more common usage. white indicates end-points and the shades of blue/green jump at usage-counts < 20 , < 40 , >= 40.

Arrows should go from parent topic-tag to child tag - but the current script does not filter out back-links so the direction is more or less random. it is not relevant for this analysis anyway.

Big Screen Plaza, NYC


Streaming Museum, an international public art and online museum, will celebrate its fourth anniversary on January 31 with the US premiere of ”Emotion Forecast” and ”Occupy Wall Screens”, real-time artworks by the renowned French artist Maurice Benayoun. The exhibition will be on view for one month at Big Screen Plaza in New York City and through 2012 at

“Emotion Forecast” and “Occupy Wall Screens” are part of Maurice Benayoun's ongoing series on the “Mechanics of Emotions” which translate emotions into maps, performances, the Emotion Vending Machine, and sculpture relics of the world.

The artworks have been developed by Robin Gareus, at the CiTu-Paragraphe Lab of the University Paris 8, in the frame of The Art Collider project as a part of the PUF program of the FACE Foundation in collaboration with the SFAI (San Francisco Art Institute).

Streaming Museum is the first global public space and online hybrid museum with collaborating locations and cultural centers on 7 continents. The 30 x 16.5 ft. HD format screen of Big Screen Plaza is located at 29th Street and 6th Avenue, adjacent to the Eventi Hotel.

back from Finland

nordkapp_jump.jpg After some creative interlude we eventually completed Carolina's trip from Ushuaia all the way down south to NordKapp, spending two weeks in Finland's Lappland on the way. - gorgeous and relaxing.

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.

Starting off with the night train from Helsinki to the midnight-sun film-festival in Sodankylä..
