This is the playground for my Arduino, Raspberry Pi and Web projects.
Strong encryption for small payloads on Arduino
Most time, the wireless communication between embedded devices like the Arduino happens in plain text. While block ciphers like AES are too bulky in terms of speed, payload and object code size, stream ciphers like RC4 do not offer a high level of security through the lack of diffusion. In this post I will describe a new method to use a modified stream cipher that offers diffusion and also works with no overhead on small payloads, that are common in such devices.
I bought a Gigabyte Brix Gaming computer, which is a pretty strong machine for its size. But it has a major drawback: it is incredibly loud. Thus I have 3D printed a case and replaced the two 40 mm fans with 120 mm ones that are quiet.
Introduction to OpenMAX on the Raspberry Pi
As I want to dive deeper into the Raspberry Pi, I tapped into the hardware accelerated media capabilities. This is my journey into OpenMAX.
Fairmount, VideoLAN Client and the Bagels
This article gives you a hint about how to get Fairmount to work in these days as it’s not supported anymore.
Camera RAW Compatibility Updates in Snow Leopard
Many updates are tied to certain versions of software that needs to be present. But in some cases it is ridiculous because the required software is also no longer provided by Apple. Buying a new computer just to be able to use a cameras RAW files is also no option.
