Today I started to add extsting git projects into my home git repository as submodules. In short: git submdule add -f ... solves the problem…

Recently I got a Korg M1. When you have a synthesizer like that you want to have a good librarian that helps you organizing your sounds, have a big sound library and so on. A quick research brought nothing helpful. So I decieded to give Ctrlr a try. The downloaded Linux version did not work as I have newer binutils installed and libbfd has no stable ABI.

In many forums and wikis the recommended way of changing the uuid of a fat partition involves dd and a hex editor.

However the easy way is to use mtools. Let's suppose we want to change the UUID of a fat partition on /dev/sda1.
As a first step we have a look at the UUIDs of the different file systems:

> blkid
/dev/sda1: SEC_TYPE="msdos" LABEL="boot" UUID="4059-33BB" TYPE="vfat"

Seitdem Debian und Ubuntu verschiedene Architekturen unterstützen ist es eigentlich relativ einfach, Windows-Software zu unterstützen. Eigentlich… Aber dazu später mehr.

wxWidgets provides a global colour database (wxTheColourDatabase). Unfortunately the documentation doesn't show the colors for an easy selection. The following code extracts the definitions from wx/common/gdicmn.cpp and converts them into HTML:

sed -e 's;^\s*{wxT("\([^"]*\)"),\([^\}]*\)\},?;<span style="color: rgb(\2)">\1</span><br />;' gdicmn.cpp |grep '<span' > colors.html


Yesterday, I stepped over a problem when I tried to connect two MIDI aware applications: Mutabor and a MIDI only filter implemented using JUCE.

I finally found some website that allowed me to configure bluez to work both as alsa and as pulseaudio device. My Bluetooth audio device is now working. The main hint comes from this post:

I didn't check everything by now, but the most important hint seems to be #2, that told me to add

Enable=Source,Sink,Headset,Gateway,Control,Socket,Media

to /etc/bluetooth/audio.conf instead of the disable option.

Additionally I put the following contents into /etc/asound.conf:

Recently, I started to fix some issues in the Bibsonomy JabRef plugin. As debugging is not possible if you don't get any information about what's going on, I tried to enable logging. According to the Bibsonomy website the plugin uses Log4J for logging. But I was unable to change the console output of JabRef. I simply didn't accept my log4j.properties.

Recently, I have been asked to try to get OpenMusic running on Linux. So far, IRCAM provides only versions for Windows and Mac OS X. Ok. OpenMusic is GPL licensed and the source code is availlable from their download page. I downloaded it, ignoring the sufficiently large list of dependencies – I can return to this topic later.

LispWorks

Though LeoCAD could be availlable in Debian soon, I wanted to install it now.

Compiling LeoCAD on Debian based systems as Ubuntu is easy as described on The official Wiki page. But there are some easy steps missing.

Lets. start: Open a shell window (xterm, Terminal, rxvt).

At first we need some software and libraries:

sudo apt-get install subversion libgtk2.0-dev libgl1-mesa-dev libjpeg-dev libpng-dev zlib1g-dev
