  1. happy 2nd birthday OpenSim!

    guess what? today is OpenSim’s second birthday! that’s right it’s just two years old and already a pretty strong little (?) bugger. to quote the official OpenSim 2nd birthday page:

    The consensus is that OpenSim was ‘born’ on Jan 29 2007, when Darren Guard (MW) made his prototypical …

  2. the mystery of the blank opengl window on screen 2

    the x200 i’m using has enough omph to power OpenGL on both the builtin display and the 1600x1200 external display. unfortunately whenever i moved that glxgears window on to the second screen it would just show…nothing. googling around for that showed that a number of people had the …

  3. addressing places in virtual worlds...or: why SLURLs are bad

    we currently are using LindenLabs’s SecondLife clients (and derivatives thereof) to login to and render our OpenSim based virtual worlds. as the SecondLife client is produced by LindenLabs for their SecondLife grid, it should come as no suprise that their client by default only talks to their grid(s …

  4. java printing & (k)ubuntu hardy

    as much as i like kubuntu 08.04.01, there is one issue that’s a pain in the netherregions: printing from java — it just doesn’t work with the sun6-java package :-( and CUPS 1.3 (which is the default version on 08.04.01): java’s printing subsystem will …

  5. using /etc/crypttab to decrypt encrypted external disk

    for a couple of months now i’ve been running my notebook from an encrypted filesystem (which works really well, i’ve to say). my external backup disk has, of course, also been converted to an encrypted filesystem.

    what has been annoying me, though, is that everytime i plug the …

  6. digitalk podcast on virtual worlds

    yesterday matthias schüssler and roger zedi from digitalk along with their technically well-versed dog visited us in rüschlikon to do a podcast about virtual worlds! having always been on the receiving end of podcasts (i just love listening to podcasts) it was a very interesting and exciting experience to be …

  7. goodbye steve

    this morning i learnt that on monday afternoon my very good friend (and colleague) steve wright died after a motorbike accident in twyford.

    to say that i’m devastated and sad is an understatement.

    all day long pictures of steve keep coming up: our first project together for a UK …

  8. happy birthday GNU!

    incredible as it is, GNU turns 25! unless you’ve been hibernating behind a big rock in a remote area almost off our world you must have heard about GNU — in fact, i think it’s fair to say that without GNU, without richard stallman and his vision we’d …

  9. opensim: isolating virtual world data and code

    for our application testing we are most of our internal grids in stand-alone mode. until last week i had been using sqlite as the underlying databases for our grids. as we gathered more and more prims on some of our regions, i noticed that loading from the sqlite databases would …

  10. GridInfo...or: client auto-configuration

    mana janus suggested last week on opensim-dev that it would be rather useful to have a grid info mechanism that would allow smart clients to obtain useful grid related parameters such as

    • login server (-loginuri parameter for the SecondLife® client)
    • grid welcome page (-loginpage)
    • URI of the economy subsystem (-helperuri …
  11. splitting opensim's chat module

    similar to other virtual worlds opensim supports in-world chat (and instant messaging) so that two avatars can “talk” to one another. the code that implements that functionality is mostly contained in ChatModule, a region module.

    OpenSim also supports an IRC bridge: you can tie your OpenSim grid to an IRC …
