Anbox - Android in a Box

April 12, 2017

Today I am making a private side-project public I am working on for more than 1.5 years now. Back in 2015 I started working on a prototype of what I call Anbox today. It was born out of the idea of putting Android into a simple container based on LXC and bridging relevant parts over to the host operating system while not allowing any access to real hardware or user data. ...

Upgrade from Debian Lenny to Squeeze

May 4, 2012

Today I upgrade my server finally from Debian lenny to squeeze (which was released already last year, but I never had the time to do the upgrade since today).

In some cases the linux userland is talking plain AT over a serial line with the modem but that's expected. Let me list some devices: Palm Pre/Pre Pus/Pre 2: All three have a MSM6280 modem chip and are using a binary protocol for modem access from the application processor. ... Read more

FOSS capabilities of the HP Veer smartphone

May 16, 2011

Yesterday HP released their new smartphone the HP Veer in the US to the market. At the same they released their webOS doctor for the new phone which is the ulitity you use when your device gets broken some way.

Here are my first notes about the device and the software it's using: ... Read more
