This is mostly just a note to myself, because I have to look it up every time I need to generate one, and the make-ssl-cert script that comes with debian doesn't appear to work.
openssl req -new -x509 -days 365 -nodes -out /tmp/cert.pem -keyout /tmp/cert.pem
Converting midi to wav using fluidsynth is not entirely trivial. Here is how I do it:
# convert opensolo.mid to fluidsynth.raw using the soundfont /usr/share/sounds/sf2/FluidR3_GM.sf2 fluidsynth -l -i -a file -z 2048 /usr/share/sounds/sf2/FluidR3_GM.sf2 opensolo.mid # convert fluidsynth.raw to fluidsynth.wav using sox sox -b 16 -c 2 -s -r 44100 fluidsynth.raw fluidsynth.wav
You can use this together with the midi export of tuxguitar to export tuxguitar and guitarpro files to wav files.
I bought myself a M-Audio Axiom 61 to play around with. It works nicely on Linux, plug & play, literally. I tried it with the demo version of Pianoteq and Fluidsynth. Both worked perfectly on the first try. I'm happy so far.
tcpdump -X tcp port 80
Yesterday, I messed up my system by trying to install a NVIDIA beta driver in order to use opencl. Today I tried again with more success. Here is how I did it:
A WORD OF WARNING don't try this unless you understand all the steps involved and know how to recover your system in case something goes wrong!
Stay tuned for some nice opencl experiment.
It looks like the problem is still there in Ubuntu 9.10, and it looks like the old fix still works. But it looks gorgeous.

Pulse audio seems to be a constant source of trouble for me while providing no benefits at all (at least not any noticeable ones). So here's how to get rid of it:
Open /etc/X11/Xsession.d/70pulseaudio in a text editor and comment out everything (put a # in front of every line) and then save it.
This will prevent pulse audio from being started when you log in.
I bought myself a new HP Pavilion dv5 notebook because my old Lenovo broke. It's a bit too shiny for my taste but anyway. Installing the new Ubuntu was a breeze. After installing I noticed that audio playback using the speakers didn't work. Too bad. So here's the solution that worked for me.
Open /etc/modprobe.d/alsa-base.conf and add the following lines at the end of the file:
alias snd-card-0 snd-hda-intel alias sound-slot-0 snd-hda-intel options snd-hda-intel model=dell-m4-1 options snd-hda-intel enable_msi=1
Reboot and everything should work again (or just reload the snd-hda-intel with the new parameters).
I hope that helps,
Jonas
Changes
Compatibility with python 2.6 means that this release should work with Ubuntu 9.04 etc.
You can fordward ports from userspace using netcat like this:
nc -l -p $localport -c "nc $remotehost $remoteport"
Example:
nc -l -p 8888 -c "nc example.com 8888"
Caution: This starts a new process for ever connect to the port.
