it is amazing on how many chips linux can run CPUs you probably have NEVER heared of 😀 OpenRISC – Academic and non-commercial use Being open source, OpenRISC has proved popular in academic and hobbyist circles. For example, Stefan […]


What are kernel modules? What exactly is a kernel module? Modules are pieces of code that can be loaded and unloaded into the kernel upon demand without rebooting the system. Without modules, we would have to build monolithic kernels and […]


you can boot a knoppix to perform those benchmarks or my debian 8 based ideal-linux-usb-stick image. BE CAREFUL WITH KNOPPIX ON SYSTEMS WITH NTFS AND LSI RAID ADAPTERS!!! (you might lose your partition table) apt-get install sysbench; # install it […]

Linux Hardware Support Detection and Survey script

download the script: (will have to be renamed to .sh and marked runnable with chmod u+x) #!/bin/bash # this script basically asks the user, if he is happy with the hardware-support of the currently running linux # it then […]


… and even more importantly – will it run Linux? Mar 22, 2017 Betakit Betakit: Volkswagen Partners with D-Wave to Adopt Quantum Technology Author: Madonna Dennis „Volkswagen says they are the first automakers to work with quantum computers, partnering with […]

The Problem with Closed Source Drivers

Unfortunately Debian – and i guess the rest of the Linux world as well – users have a pretty hard time finding WIFI and LAN cards but also grafix cards that can run with 100% free software. (FSF! STALLMAN! HELP! […]


pcDuino3 jumping up on the latest MicroMicro-Mini-Low-Power-Low-Cost-Computer train: Arduino actually startet off with Atmel-CPUs which could do all sorts of automation and measurement industrial applications… but were not really usefull as PC-replacement or Gaming-Consoles 😀 actually i try to establish […]


Hardware Assembly: (i think 512MByte should be enough, 1GByte probably pretty good) Software Installation: including squid-proxy and web advertisement-filtering in the next part: OpenVPN 🙂 Thanks man! Amazing tutorials! by Related Links:

Was macht eigentlich ORACLE?

Jeder kennt Steve Jobs (now dead) – aber wer kennt schon „Larry“ Ellison? 😀 Oracle hat 2010 die Firma „Sun Microsystem aufgekauft“ und damit OpenSource Technologie wie Java, VirtualBox und MySQL eingekauft. Lawrence Joseph „Larry“ Ellison (born August 17, 1944) […]

i would love iceland or any government come forth on that issue – developing and standardizing free hardware (from phones to laptops to 3d printed houses?) for it’s free citizens – without closed-source-binary-blobs and drivers. Further hardware resources: […]

Open Source Hardware

while this is not exactly the same as „free hardware“… it is still a step in the right direction. Here is a list of OSHWA approved hardware projects:   1 UID Project Name Brief Project Description Link […]


So it seems pretty hard to find a grafix-card that runs on completely open source and not closed-source drivers. we try never the less we try. Reception and impact Cover for „Open-Source Lab“ by Joshua M. Pearce (2014). […]

Open (Plans-Source) Hardware – DragonBox Pyra – designed in Germany

the massive challenge for Open (Source/Schematics/Plan/Recipe) Hardware seems the grafik-card… which often runs on closed-source drivers. This is true for the raspberry pi (it even needs binary-closed-source-blob to boot), for the EOMA68 project and the pyra. holy cow this thing […]
