Recently the main Linux website, kernel.org, was compromised by an hacking attack. Since then, Linus Torvalds decided to use GitHub as the master repository for the whole kernel (here the announcement), and kernel.org has been down for a long time. This has broken some of my old tutorials on this blog. In my tutorials, I […]

I recently bought a Bluetooth cardio sensor, the Zephyr Hxm. Its selling points for me were the ability to use it together with my Android smartphone and the fact that Zephyr encourages developers to access its functionality through an open SDK. The package contains: The sensor, which is very light but feels sturdy. On the […]

PyPy as a faster alternative for Python

June 7, 2011

It came to my attention today that there’s an alternative interpreter for the Python language which is faster and often viable: it’s called PyPy and uses Just-In-Time compilation to execute Python code. Just-In-Time compilation is a technique that is used successfully in many projects: the .NET Framework, Java, QEMU, … and it has also been […]

Ubuntu 11.04 Natty Narwhal has been just released. I’m curently seeding the torrents of the installation images, I feel it’s a small yet effective thing to do to reciprocate the benefits I get for using Ubuntu since 2007, when the release was called Feisty Fawn. I went to the Ubuntu alternative download page, downloaded the […]

ZPUino is a project that offers a microprocessor that can be put on FPGA, and that can be programmed with a simple IDE. Everything is open source: the toolchain, the IDE and the VHDL code; and it can be downloaded freely. The hardware architecture is based on the ZPU (Zylin CPU), which is a processor […]

I really wanted to try Arduino; Arduino narrates a story where the good guys are winning. Saturday I arranged to buy one, the Arduino Uno, and the first thing that came into my mind was “Wow, it’s really smaller than I thought possible!”. I went home and started unboxing it: the packages comes with a […]

Simulating AT91 with Skyeye

September 27, 2010

Atmel AT91 is a series of common microcontrollers that contain ARM cores. The AT91SAM7 series in particular runs the ubiquitous ARM7TDMI. I found out that there is an open source program that emulates these microcontrollers (among many others): it is Skyeye. Skyeye is a project that emulates big and small microcontrollers, and for this reason […]

The guys at OpenCores released a new version of their OpenRisc core, tweaking many hardware bug but also porting Linux kernel 2.6.24 to their simulation platform, that is called or1ksim. The procedure (found here) to try Linux on the new simulator is straightforward and involves executing a script. The script hides most of the complexity […]
