I got Raspberry Pi 2 as a present from my brother. It’s a nice toy, I was trying out OpenELEC, it makes for a really nice home theater in combination with a NAS on local network. The only drawback was that the analog sound output produced kind of unpleasant noise. I tried to follow a lot of pieces of advice found around on forums, changed the operating system, drivers, nothing helped. It seemed that the noise was a design problem of the analog sound (the digital sound output was all right).
In the end, I installed Raspbian and started using this Pi as a “thin client” to connect to other computers using X2Go remote sessions. It was a nice use case, but I didn’t need it so often as to actually miss sound. Eventually, I was advised to use an external sound card. A small, $10 USB card did the trick. The noise was gone and now, when using Raspberry as a thin client, I’m able to listen to music on it, too.
Spending a lot of time with mouse and keyboard, I decided I would give it a try with trackball. A friend lent me Logitech Trackman Marble for a week to see if I can get used to it. The one drawback in Linux is that there’s no support for scroll emulation by default. It was relatively easy to set this up on my laptop with help of xinput, but at home, where I’m using Debian 9 (currently ‘testing’ branch) with Mate, this didn’t work. So this had to go to a good old X.Org configuration file:
# cat /usr/share/X11/xorg.conf.d/50-trackball.conf
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Option "ButtonMapping" "1 2 3 4 5 6 7 8 9"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "8"
Option "ZAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
Option "Emulate3Buttons" "true"
Option "EmulateWheelInertia" "10"
# cat /etc/debian_version
By the way, after two days of using it, I think I’m getting used to it, so I’ll probably buy one for myself.
Yet another game from the 90’s that I wanted to tick off as done. Here are a few screenshots:

kids helped a lot
I’ve been tinkering with my computers ever since the days of ZX Spectrum, more or less. In the last eight years or so, however, people would come to me with their broken laptops and computers every now and then. It didn’t happen too often to become a nuisance; instead, it was a welcome distraction from my regular daily tasks (with the exception, maybe, of the time when I had seven laptops at my office at once 🙂 ).
