I found very profound best practices for git on github. Well done!

I found a nice tool for editing and testing crontab-entries.

A sysadmin needs his tools. I really need at least 3 tools to be productive:

• Terminal-Emulator (or screen/tmux if I am working without X)
• Shell
• Editor

This is my Rule Of Three. Those 3 tools can make my life much easier. Therefore I have to choose those tools wisely. And of course I have to know them very well, so I can get all the benefits of them. The last time I wrote about rxvt(Terminal-Emulator). In this article I want to introduce one of my “favourite” shells: zsh

After years of hoaxes about the date, it finally happend: The Future is NOW! Don’t wonder if you see a guy called “Marty” or a scientist called “Doc”. They are just visitors from the past…
