The new webp image standard is used a lot this days. Somehow Nautilius is not generating thumbnails for this format automatically. To add support for this just do the following: STEP 1: Add support for the new image format. Create a new file /usr/share/thumbnailers/webp.thumbnailer with the following content.

As you maybe discovered there is no rpm build support from the Signal team. Yes you can compile your own version and then do that for every new release but if you are lazy like me and nor an international wanted person (like Assange) there is a simpler version to do it. Here comes the… Read More »
Another post that focuses on some smart one liners in Linux. Who is using my port ? ss is the new replacement for netstat. Same parameters can be used but gives more information.
A simple one liner to kill all the processes having the same name or token in the name (myprocess): kill -9 $(ps aux | grep myprocess | awk ‘{print $2}’) This is a very effective way of cleaning up stuck processes that were spawned by some gone wrong software.
The bash one liner of the day is to find and kill a Java process using one liner. In my case I have a Jboss application server domain that is stuck. By using jps command that displays only the running Java processes is a no brainer to kill the process by using a token that… Read More »

In my case I all the labels are kept in Java property files with “.properties” file extension. Then for each language I have… Read More »
Reinstalling things like Oracle is always a hassle and takes about one day to make it work. Lucky for me I made a full back-up of my old disk when I upgraded to a new laptop. On the new laptop I did a fresh install of Fedora 28. The idea is to migrate my old… Read More »
Generation of core dumps that result in freezing the Linux system is another common issue in the new Linux kernels discussed on many forum threads. Same as the bug of kswapd0 discussed here Kswapd0 going haywire this can become very annoying. It seems that lately someone tries to add developer features turned on by default… Read More »
I like when solutions you are excited about and are first seen as “experimental” start to go mainstream. This happened with containers (Docker, CoreOS, Kubernetes etc.) which are now the hottest topic in DevOps right now. The same is happening now for Apache Kafka which was adopted by no other than “Goldman Sachs” for their… Read More »
