freki design changes
2016-11-11
Another day, another bugfix and feature session. freki now has a better overview (articles). The old system was a little clumsy and screwed up when faced with strange situations. Therefor, the article overview now includes ALL articles ever written. ;)

This may seem stupid and not ideal, but for the time being, I am satisfied so far. Because of this changes, I allow myself to increase the version to 0.7. Have fun!
Back on ArchLinux
2016-11-10
After some time of fiddling around with Slackware now, I decided to switch back to ArchLinux on my main machine. Partially, because at some point it ended being fun searching for dependencies on Slackware, and partially because I missed pacman. slackpkg did a really good job on Slackware, but could not resolve dependencies.

I am not 100% confident that this switch will be permanent. Since Slackware was my first distro to touch about 16 years ago, I learned to really love it. There is much nostalgia involved in this decision. I like the Slackware community, I like how Patrick Volkerding does things and I like the pure simplicity of it. But, as mentioned, then there is pacman ...

If someone ported pacman to Slackware (slackman ;) ?) I would be first in line to try it and switch back to Slack.
SlackwareARM + PiNOIR camera howto
2016-04-27
I am on SlackwareARM on my Raspberry Pi 2 and have the PiNOIR camera connected to it. At first I thought it should be pretty easy to accomplish, but it turned out to be trickier than I thought.
At first, I couldn't find reliable information whatsoever, but after some more specific search terms I found a solution that worked.

All these steps are meant to be executed by root

Step 1 - download and install raspberry pi userland tools
cd /usr/src
git clone "https://github.com/raspberrypi/userland.git"
mkdir userland/build
cd userland/build
cmake ..
make
make install


Step 2 - apply permissions to devices
usermod -a -G video 
chmod 0660 /dev/vchiq
chgrp video /dev/vchiq
echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules


Step 3 - Modify library paths
echo "/opt/vc/lib" >> /etc/ld.so.conf
ldconfig


Step 4 - create a file called /etc/profile.d/videocore-paths.sh and edit it like this:
#!/bin/sh

# For root users, ensure that /opt/vc/sbin is in the $PATH.
if [ "`id -u`" = "0" ]; then
    echo $PATH | grep /opt/vc/sbin 1> /dev/null 2> /dev/null
    if [ ! $? = 0 ]; then
        PATH="$PATH:/opt/vc/sbin"
    fi
fi

# Add videocore utilities to system $PATH:
PATH="$PATH:/opt/vc/bin"


Step 5 - make it executable
chmod a+x /etc/profile.d/videocore-paths.sh


Step 6 - modify config.txt 
echo "gpu_mem=128" >> /boot/config.txt
echo "start_file=start_x.elf" >> /boot/config.txt
echo "fixup_file=fixup_x.dat" >> /boot/config.txt
echo "disable_camera_led=1" >> /boot/config.txt


Please make sure that your config.txt has the new values in it and then reboot and enjoy :)
If everything worked, you can try:
raspistill -o test.jpg

to test if it really worked. If it tells you something about permissions, make sure your user is in the video group.
