I really love sqlite3 databases. They are small, scalable and just do the job. The only thing they need is a file, so they are also much easier to configure, maintain and backup than heavy database solutions like MariaDB, MySQL or PostgreSQL. For bigger class applications they do a very good job, for most of… Read More »
I share one of my Iceland pictures because I think it makes a great wallpaper. Feel free to use and to share (CC BY-SA 4.0 Licence). The picture is as well on unslpash.com Screenshots And this is how it looks in elementary OS
http://www.arrl.org/news/american-red-cross-asks-arrl-s-assistance-with-puerto-rico-relief-effort They are doing something really meaningful, and I have to sit here on my desk doing some gamma-ray computations. Man, I really need to finish my PhD soon 🙂
I've written a small bash-script that should make the process of building your own LineageOS easy. The script is on GitHub, including a how-to-use readme. Have fun! 🙂
Just some time ago, I let myself go and wrote about how upset I was about the (missing) support for my new RX 470 on Linux. Today AMD released the amdgpu-pro driver 17.30, with support for Kernel 4.10 and Xorg 1.19. So my setup is finally not useless anymore. Details are on the AMD download… Read More »
The doomsday clock is at two-and-a-half minutes to midnight. The doomsday clock is a illustration of how close we are to a man-made global catastrophe, published by " The Bulletin of the Atomic Scientists' Science and Security Board". Last time it was at that level has been 1953, during the tests of the Hydrogen-Fusion bombs.… Read More »
Because of heavy rain and thunderstorms this weekend, I had some time to work on my lightning monitor again. With success, I could reduce the "DISTURBER DETECTED" messages significantly by putting the device away from the laptop. Even better, it was starting to measure lightnings during one of the thunderstorms! Great 🙂 The data makes… Read More »
I hacked a C++ tool for converting GPX files to GeoJson, because the only one I could find used Node.js. The tool is available on GitHub. Binaries are available for GNU/Linux, the tool should be compatible with MacOS and Windows (Not tested). Runtime comparison with togeojson (Node.js)

I recently purchased a MOD-1016 chip for lightning detection in order to improve my weather station. The chip is based on the AS3935 chip and ships as a complete I2C-ready breakout module from embedded adventures. First steps I skip the following parts because I consider them trivial: Soldering Wiring to a Arduino Nano The wiring… Read More »
About a month and half ago I purchased a RX470 and I want to write my experience with the card so far. I am not happy. Originally I wanted to have a nVidia GTX 970. But the RX470 had 8GB RAM instead of 4GB and, more interestingly, the double precision float operations should be significantly… Read More »
