Recently, I have been thinking about how to organize the things I've been doing over the last years. I happened to post a little article on my blog from time to time, but I feel that this format becomes a bit messy as time goes by, and that it doesn't …
I deployed a Ceph cluster (Nautilus, then upgraded to the Octopus release) to store my personal data a few months ago. So far it has been working pretty well, apart from a 1 hour partial outage that won't be covered there, most probably linked to the issue described.
That said …
This is the story of me attempting to convert an old machine into a Cryptocurrency miner. I basically tried to plug my AMD Radeon RX 480 graphic card into an old PC, a Core 2 duo with 4GB RAM and a GF7050T-M5 motherboard.
According to the GF7050T-M5 manual, its PCI …
This post summarizes the results of my AMD GPU benchmark code to benchmark the computing power of an AMD Radeon RX 480 GPU against an Intel Core i5-7400 CPU.
The benchmarking code I am running on is the following code:
__kernel void kerntest(__global char* data, int loops_cnt) {

Installing a Vanilla Linux Kernel on Fedora is quite simple (once one knows how to do it..)
One can start by cloning Torvalds' Linux repository to fetch the latest master (or we could fetch the latest stable release) :
$ git clone https://github.com/torvalds …There is a whole lot of files in the Documentation directory of the
Linux kernel source. Is it possible for a single person to read
the whole documentation ? Let's have a look at what's inside it.
$ pwd

To follow-up on my previous blog post about driving a YM2149F chip with an Arduino, I wrote an Arduino firmware that can be used together with a PC side Python script to send music to the YM2149F. All the code is available in the ym2149-streamer repository on GitHub.
A few months ago, I had the opportunity to get a Yamaha YM2149F chip. This chip is basically a clone of General Instrument's AY-3-8910, "a 3 voices programmable sound generator" widely used in the 80's in many arcade games and home computers (including the Atari ST and Amstrad CPC).

There is already a number of resources available about programming the Arduino with or without the IDE (I won't discuss here the pros and cons of using it). This aims at being a quick memo for those who already have some knowledge about C programming, and just want the minimal …
