X11 is the mother of many things, one being remote computing. Since X11 is still the graphical engine on most modern Linux distributions these now old-school X11 functionalities are still usable. Just for fun, I set things up on Ubuntu and OS X Mavericks, without using SSH. This is important since SSH has the -X option for tunneling X11, which makes a X11 client server configuration very simple. And thus you can find guides to do this all over the internet. X11 works best on a LAN and SSH tunneling is not needed when connecting over a LAN. Also SSH tunneling kills your performance due to encryptionRead More →

In 2012 I moved from the Netherlands to Bremen, Germany. Both countries being part of the European Union, a work permit is not required. Obviously, a lot of things are different in Germany and many information regarding this subject is available on the Internet.
