Systemd problem
At home, I’ve been using rolling release of Debian for my desktop for quite some time. The good thing about it is that years go by and you need not worry about the end of life of this or that…
Skype in Docker

CentOS 6 and MiniDLNA

Broken MATE panel
Following an upgrade in Debian Jessie/testing, I was left with no panels at all after logging into the MATE desktop. Running dpkg -s mate-desktop, I saw that MATE had been changed to 1.8 from the previous 1.6 version. My first…
