About Stefan Helander
I was born a nerd! As a child I was fond of fiddling with all kind of thechnical stuff, discovering how things work and often fixing them. As a 6 year old I fixed my grandmothers 220 volts wiring.
The interest in technical stuff grown even bigger in the teenage years where I got my amateur radio license and developed a keen interest in computers.
Today I am proud to be a nerd. It is a part of my profession.
To all of you nerds and geeks out there - remember that nerd is the new sexy! :)

It turned out the reason for this was changed permissions on the /tmp folder (caused by restoring a folder with BackupPC to /tmp instead of it’s original location). Solution: After this apt update worked as normal.
By using word-wrap, word-break and overflow-wrap in CSS you can control the browser’s behaviour when it comes to word wrapping. However, it is not possible to control where the word breaks. It just breaks when the word no longer fits in the container. To indicate where a word can be broken, the soft hyphen can […]

I had a rather large Akeeba Backup file (about 25 GB) which I tried to restore using Akeeba kickstart from the web browser. It took a long time unpacking the archive but never reached the point where database is being restored. The Akeeba kickstart (version 5.0 or later) can be run from command line (shell) […]
The antenna seems always to be a compromise between practical matters and performance. While not being the most high performance antenna, I find the end fed half wave (EFHW) a very practical antenna, especially during portable operations. The EFHW doesn’t need to be straight. It can be bent in angles and be “abused” a lot. […]
