Site Clean-Up

Blog categories: 

You might have noticed, I made this site a bit cleaner and added the possibility for you to support a bit by flattr. The search field is now in the header and the right sidebar is completely gone. Just in case you’ve been searching for it… ;)

Add SSH Public Key With One Command

As I always forget the exact syntax and am too chicken-hearted to fool around, I note down the command to add one’s public key to the authorized keys on the remote machine (to login using pub/private key pair only) here. Use the following command ( might be on your site).

Furthermore, I noticed several crashes of my ssh sessions.
