Palacsinta
A Hungarian crepe like pancake. Could be served with different fillings, sweet and salty. One of the sweet famous is the “Gundel Palacsinta” or the Hortobagyi.
This is the best recipe I got out of my mothers old cook book.

linux 3.0.4 on a GA-MA78G-DS3H boot without stuttering
Since a few months I wonder why on my workstation newer kernels than 2.6.37 are stuttering or even stopping (failing to boot). Some times the stops could be resumed with just typing on the keyboard or pressing the power button. Finally I had ACPI in mind as an suspect and experimented with some ACPI boot options, and came out with a solution: acpi_skip_timer_override. It skips a timer which is automatically on for some bad hardware (motherboards). My is a crappy one but not listed in the description. Maybe the latest bios update changed some ACPI parameters. Dunno. I didn’t investigated this issue further, even not checked why this problem was introduced after 2.6.37. Just for someone who also owns a crappy Gigabyte GA-MA78G-DS3H place: acpi_skip_timer_override as boot option in your grub.conf and you are fine.

Snowy on softmonsters
To have my own sync repo for tomboy, I installed snowy on softmonsters.
I mainly followed the mod_wsgi howto at: http://live.gnome.org/Snowy/Install/WSGI
I needed to make it a full virtual domain. A subdomain in this case: snowy.softmonsters.com.
The essential configuration, for a non ssl-site, in sites-available is:
WSGIRestrictStdout Off
ServerName snowy.softmonsters.com
WSGIPassAuthorization On
Alias /media/ /usr/lib/python2.5/site-packages/django/contrib/admin/media/
WSGIDaemonProcess snowy user=joy home=/home/joy/snowy
WSGIProcessGroup snowy
WSGIScriptAlias / /home/joy/snowy/snowy.wsgi
Options -Indexes FollowSymLinks
AllowOverride AuthConfig FileInfo
Order allow,deny
allow from all
Options -Indexes FollowSymLinks
AllowOverride AuthConfig FileInfo
Order allow,deny
allow from all
ErrorLog /var/log/apache2/error_snowy.log
CustomLog /var/log/apache2/access_snowy.log combined
LogLevel debug
I need to set WSGIRestrictStdout Off because snowy spits out some debugging information in it’s default configuration. I additionally set custom logs, to better identify snowy problems.
Don’t forget to set your host/domain name in the DB. For sqllite consult the docs how to manually edit a table.

Eggs and Kids
The eggs are running, mostly. There are still problems with the borders and irritating IR-signals but I have Ideas how to solve this issue.
You can visit this permanent robotic installation at BMW world Munich.
But the girls are all right.

Find your continent
While travelling home by train i thought about the navigation for the “egg” robots to find home into the allowed playground. I tried several possible methods mostly in favour the so called dead reckoning using sensor data collected from the wheels and compass. But this is all over complicated to handle and naturally erroneous in time. I came up with the simple approach to find back with the data of the last left IR-field and the compass. This is somehow like searching for continents but should be efficient.
This sketch shows the turn back angle depending on the last left ir field:

Running Mike
So after some real programming. Adapting the new laser scanner, changing the protocol version to the embedded board and some other adjustments Mike is running.
See him here: http://vimeo.com/8584913
Sorry for the bad quality, but old camera and bad conversion.
The video is 2 weeks old so some improvements have been done. Tomorrow we will travelling to Hannover. Hope “Daisy” will not stop us.

Implanting the eye
Today I mastered the second big hurdle for implementing a new eye into a robot system.
The story is: for a new show an autonomous tracking system, which is based on a hokuyo laserscanner, should be overhauled. It is for a robot of course. I post images later of my new friend.
For this show the laserscanners changed. They are now connected via USB and the protocol version bumped to 2.0. (SCIP). Today i integrated some sample libraries from hokuyo into parts of our steering software. Even the mapping is added. So far the data looks very right.

direct link to live streams
it is amazing how some radiostations try to hide their direct stream links, to make life harder for users who don’t want to click through tons stupid webpages, popups and don’t want to install even more stupid plugins.
here are some direct links from some of my favorite radiostations. i will update this list.
an other link for fm4. why the heck do they change it?
so listening to one station is as easy as: mplayer mms://streamy.orf.at/fm4_live
why fm4 offers only a windows-media-stream is still a mystery to me. since it is a state founded austrian radio-station they could effort encoder machine with icecast on it, for sure.

emacs for lisa
ever wanted emacs for mac os x, then check this out: http://emacs-app.sourceforge.net/
it is much cooler than emacs over fink or the cocoa-port. it has a native aqua-interface and comes from a brand new trunk (23.0)

64bit lightning.xpi 0.7
since my calender_for_google_provider addon (really a nice tool) requiered lightning-0.7 i built one. for whatever reason there is no official 64bit-built for lightning.
i followed this guide http://www.mozilla.org/projects/calendar/lightning/build.html
but the cvs-source isn’t really usefull, you need to have the 0.7 source, which could be downloaded here: http://releases.mozilla.org/pub/mozilla.org/calendar/lightning/releases/0.7/source/lightning-sunbird-0.7-source.tar.bz2
i built it with follwing params:
export CFLAGS="-O2 -pipe -fPIC"
export CHOST="x86_64-pc-linux-gnu"
as it is suggested here: http://blog.crox.net/archives/28-Lightning-for-x86_64-Linux-amd64.html
you can download my built from:
