Installing Ubuntu Karmic Koala

October 31, 2009 / / 4 Comments

I have been looking forward to Thursday’s release of Ubuntu 9.10, code name Karmic Koala, for some time now. CouchDB integrated into the desktop — sweet!

The actual install overall went really smooth. Installer got streamlined a bit more and now carries over the initial language selection to defaults for time zone and keyboard settings. Most complicated about it was my chaotic partition layout on my dev machine. Installation went all fine, all devices recognized. At first I had problems with my Wacom Bamboo graphics tablet because copying over the old config created double entries for all devices, making X choke and kill my USB mouse. Just commenting out the entries in my X config solved that problem. I just had to redo the basic configuration from Gimp by invoking the Gimp Preferences Dialog under Edit -> Preferences, select input devices in the tree, then “Configure Extended Input Devices”. There I just set the mode of all auto-discovered wacom devices to “Screen”. (not “Window” or “Disabled”).

Things turned out to be a bit more work than initially planned when I discovered that the MythTV frontend from karmic wouldn’t connect to my mediahub computer, a Eee Box B202 with dual DVB-T tuner ( TerraTec Cinergy DT USB XS Diversity , newer hardware-rev). After the initial troubles I had first getting the DVB-T to work perfectly, I was really not eager to change anything about that system.. In fact it was still running an updated EasyPeasy 1.0.

But my fears were totally unfounded. The DVB-T stick was now auto-discovered and there just needed one module option to be added in a newly created /etc/modprobe.d/options :

options dvb_usb_dib0700 dvb_usb_dib0700_ir_proto=0

This sets the remote control protocol to NEC, which is something my remote control needs. Everything else basically worked out of the box. I just had to configure MythTV and tell it the two DVB front end devices and EIT create video sources and connect those two. After copying over the randomly generated mySQL password to the laptop, I was back at my old setup.

What changed is that both computers now boot a lot faster and look a lot prettier, even using only graphics that come with Karmic Koala

Congratulations to the ubuntu team for producing such a fine new ubuntu version, better than ever.

Hood Beta 2

October 20, 2009 / / 0 Comments

After fixing a pretty serious bug in the combination of svenson and jcouchdb and releasing svenson 1.3.4 and jcouchdb 0.9.1-4 and jcouchdb 0.10.0-2, I got around to release a new, improved version of Hood, too. It’s called “Beta 2” and still lacks some features but the documentation is a lot better and the application design is basically what I think will be the final layout of things.

Head over to google code and grab yourself a copy.

Hood: example application for jcouchdb 0.10.0-1

October 15, 2009 / / 2 Comments

On the occasion of presenting CouchDB and jcouchdb at my place of work, I got around to finally create a small example application that is now downloadable as sneak preview. There need to be bugs fixed, features implemented and lots of documentation to be added, but it kind of works.

It’s called “Hood” for neighbourhood and allows you to mark places or people around a place of activity of yours, called hood. it is meant to foster collaboration / tips on local places etc.

It’s Spring Web Application demonstrating some techniques of working with jcouchdb. It’s an eclipse WTP/Spring IDE project with all dependencies you need besides couchdb and tomcat or another servlet container.

Stay tuned for hood to grow into a fullblown app.

Twitter/IRC integration with boticelli

October 6, 2009 / / 0 Comments

I have been planning to release my IRC bot project as open source for quite a while now and the recently added twitter integration gave me the final push to actually do it. So now I am proud to announce the inital release of boticelli, a java / spring IRC bot/web application based on the martyr IRC library. Its mean to be easily configurable and extendable and ships with lots of plugins already included.

Available Plugins:

  • Logging – log channel conversation and provide a web interface to browse and search them
  • Seen – Remembers when a user last spoke in the channel
  • FAQ – Manages a keyword list of FAQ keywords that are matched to a description. Useful to provide answers for reoccuring topics in the channel.
  • AccountCreator?/Revoke/Grant – commands to automatically create accounts for the webapplication and to revoke / grant web app access rights (for ops)
  • ServerPing? – plugin that detects broken connections and makes the bot reconnect.
  • Say – plugin to let the bot say something or make it do something (a CTCP Action)
  • Twitter – two way integration into twitter over a bot specific twitter account.

So if you’re into old-school IRC fun, head over to google code and grab yourself a copy.
