Back in 2012 we blogged about Meego/Mer/Nemo, Android for x86 and other Linux operating systems for touchscreens and tablets. Back in the day we also compared Ubuntu Unity vs. Gnome 3 and which would work better as a touch operated system, and Gnome 3 was clearly the more mature system. Since then Ubuntu has dropped Unity […]
In our previous article we described an idea setup for a modern server with btrfs for flexibility and redundancy. In this article we describe another kind of setup that is ideal only for a backup server. For a backup server redundancy and high availability are not important, but instead maximal disk space capacity and the […]
Btrfs is probably the most modern filesystem of all widely used filesystems on Linux. In this article we explain how to use Btrfs as the only filesystem on a server machine, and how that enables some sweet capabilities, like very resilient RAID-1, flexible adding or replacing of disk drives, using snapshots for quick backups and […]
Btrfs (pronounced Better FS) is a relatively new filesystem that operates on the copy-on-write principle (abbreviated COW, which stems a more friendly pronunciation for btrfs: Butter FS). Btrfs includes a lot of interesting functionality and replaces traditional Linux disk and filesystem tools like LVM (volume manager, disk snapshots) and mdadm (software RAID). In RAID usage btrfs is much more flexible […]
With billions of devices produced, Android is by far the most common Linux-based mobile operating system to date. Of the less known competitors, Ubuntu phone and Jolla are the most interesting.

OpenFOAM (Open source Field Operation And Manipulation) is a numerical CFD (Computational Fluid Dynamics) solver and a pre/postprocessing software suite. Special care has been taken to enable automatic parallelization of applications written using OpenFOAM high-level syntax. Parallelization can be further extended by using a clustering software such as OpenMPI that distributes simulation workload to multiple […]
The OpenPGP standard and the most popular open source program that implements it, GnuPG, have been well tested and widely deployed over the last decades. At least for the time being they are considered to be cryptographically unbroken tools for encrypting and verifying messages and other data. Due to the lack of easy-to-use tools and […]
