Raspberry Pi 2 Announced

Posted on by

The announcement of the Raspberry Pi 2 earlier this week made me happy. The thing I felt with the RPI version 1 is obvious the lack of CPU power. The version 2 has roughly 6x it`s power and 4 cores. Along with double RAM memory (1 GB compared to 512 MB) it`s now a beast in a box for its 35 bucks.

Just a couple of hours later Microsoft announced Windows 10 support for the Raspberry Pi 2 (source)
This means the RPI2 will be my new tool of choice for most programming languages. It already supports  C, C++, Java, Scratch and Ruby. It might support J and VB too when Windows 10 comes.

Ubuntu Linux Kernel 3.19 installation guide

Posted on by

This short walkthrough describes how to install the Ubuntu Linux Kernel 3.19 (server and desktop/client) without compiling.

This guide should work with the latest version of Ubuntu Linux and most Ubuntu-based distributions including Mint. The included kernel files have been compiled using the generic Ubuntu configuration. The general packages are available for 32 bits systems (I386+) and 64 bits (AMD64) and both as low latency.

Installation Guide (GUI)

  1. Download the kernel headers package:

    http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-headers-3.19.0-031900_3.19.0-031900.201502091451_all.deb
  2. And the appropriate package for your system
  3. And the accompanying compiled kernel image
  4. Install the files in the same order as downloaded above. So first install the headers (2 files) and finally the image (1 file).
  5. In the terminal run:

    sudo update-grub
  6. Reboot and select the kernel from the bootloader menu

I will post the latest version of the 3.19 branch and 3.20 release candidates in comments below.
