Skype in Docker
Although jabber is my preferred IM protocol, sometimes I have to communicate with people who, for some reason, only use Skype. On Debian, that can be quite a problem, supposing you are not particularly keen on weed infestation of your…
AWK – print no newline
Using awk to display information, the print function, by default, adds newline after each iteration. I wanted to copy the results and use them as an actual array in a program and preferred to have them all on one line,…
CentOS 6 and MiniDLNA
I’ve got a small home server made from a half-broken laptop nobody wanted any more. The screen was’t working, but otherwise the machine was fine, so I took it, shipped Centos 6 on it and it’s been serving as a…
Mount a disk image containing LVM
If you have an image with standard partitions, you can mount any partition as a loopback device using the offset given by fdisk:

The sda5 partition starts on sector 204804096. We know from fdisk -l that one sector is…
Observium and SNMPv3
Some tasks you find yourself doing only once in a while, so they never stick in your memory for too long. Adding a new device to Observium (a great monitoring tool), and that device being off the premises, so it’s…
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…
GPG encrypted files for Amazon Glacier storage
I am no big fan of cloud solutions, mainly because I don’t like to entrust my data to people I don’t know. But like with any other tool, the cloud is still just a tool and it really depends on…
Delete huge amount of files in a directory
I had this peculiar problem – one of my virtual hosts had a custom tmp directory where sessions were stored and not deleted for a long time. When I found out, the number of files in there already posed a…

However, it wouldn’t start automatically after logging in, see:
