  1. we have buttons!

    since time immemorial (well, almost) i own a private epson 1260 scanner. a couple of weeks ago i — foolishly, as it turns out now — offered to my in-laws to copy all lake district articles out of our country walking collections. foolishly, because i realized that country walking must have their …

  2. RESTful regions

    we are currently trying to figure out what the best approach for a REST “API” for regions is and would like to solicit comments :-)

    currently the idea is to have a scheme as follows:

    • http://opensim.foobar.org:9000/admin/regions —
      • GET returns an array of (UUID, name, x location …
  3. which serialization format for OpenSim REST services?

    we are currently looking at adding REST support to the RemoteAdmin plugin (other stuff to follow) — the idea being that we can get information about (as well as change state of) a running OpenSim instance not only via XmlRpc but also via REST.

    looking at the way we currently deal …

  4. fixing absurdly high wordpress CPU loads...

    ever since i switched to wordpress 2.5 (and 2.5.1) i was experiencing absurdly high CPU loads whenever i posted a new blog entry or changed a page — culminating in loads of 124+ yesterday, effectively bringing our server to a standstill! :-( not good. not good at all.

    a …

  5. console-less opensim

    until a couple of days ago, opensim would only run in console mode: whenever you started OpenSim you would end up at a prompt inside OpenSim’s very own console — which is very convenient if you want to manage it that way. it is rather inconvenient if you want to …

  6. proper footnote IDs for markdown-extra.php

    i realized the other day that the markdown-extra plugin i am using for text markup was generating non-unique footnote anchors, resulting in any footnote #1 in a blog entry on referring back to footnote #1’s anchor in the very first blog on a page with multiple blog entries. not …

  7. installing mono 1.9

    to run the most recent libsecondlife release you need to have at least mono 1.9 installed. the following step-by-step recipe applies to a ubuntu 7.10 system and you should be root:

    installing pre-reqs

    apt-get install build-essential bison gawk
    apt-get install libglib2.0-dev
    apt-get install libpng12-dev libx11-dev libfontconfig1-dev 
    apt-get …
  8. being slartibartfast...

    tonight i felt like being slartibartfast — yep, the urge to create some fjords, mountain ranges, and islands was just overwhelming. unfortunately, the previous routes to scratching that itch were blocked: using L3DT to generate a nice looking landscape (all by just twiddling a couple of sliders) and then loading the …

  9. ubuntu 7.10: fixing emacs flyspell & transient mark mode bug

    while working on a lengthy LaTeX text in my favourite editor, emacs, i noticed that once i turn on flyspell-mode (spell check as you type), that transient-mark-mode (highlight marked regions) would become borked :-( not good.

    investigating the issue, it transpired that the flyspell.el and ispell.el files installed as …

  10. debugging qrcode...

    as you hopefully have not noticed (well, there was some downtime, but not more than usually afflicted by cablecom) i switched xyzzyxyzzy.net from gentoo to running ubuntu server 7.10 on monday.2 along with that came a reorganization of the web server directory layout — and i took the …

  11. installing OpenSim on PowerPC...or: of eggs and virtual worlds

    we noticed last week (well, actually a bit longer than that) that OpenSim would not really care to run on PowerPC platforms. the symptoms were that (a) it would die with an array index exception on restart, and (b) the SL client would crash horribly when connecting to the region …

  12. patching pidgin to recognize F19/F20

    my X60 keyboard has those rather convenient “next page” and “previous page” keys (located just above and to the side of the cursor keys) which i’m using to switch to the next or previous tab in konsole and firefox:

    • adding support for that in konsole was rather easy: just …
  13. OpenSim...or: your very own secondlife grid in 3 easy steps...

    want to run your own secondlife grid? not satisfied with that lousy 512m² plot in the middle of that sleazy, red-light district sim somewhere on a remote secondlife island on the LindenLab grid? ever dreamed of becoming a railway tycoon and running a railway company in secondlife — but couldn’t …
