We use Debian for our systems. Not only because we love it, but also because you can harden and secure it very well. One of the many security precausions for Debian-based Linux distributions are unattended upgrades.
This time I’d like to talk about some some useful tips how to move through a file. Vim motions and marks cannot only be helpful to jump to a specific location, but also to select, copy-paste and delete text passages.
This time I’ll show you how to undo, redo and repeat stuff in Vim. With just a few simple keystrokes you can improve your daily workflow.
In this blog post, I’d like to show you how to use Vim to open and edit multiple files. Use the right techniques and you’ll be even more productive in handling multiple files at the same time.
I think every *NIX admin knows this little gem – the Vi or Vim (Vi Improved) text editor. While the origin vi was written by Billy Joy, vim was cloned, improved and released in 1991 by Bram Moolenaar. In the blog series Mastering Vim, I’d like to show you some tips & tricks.

When it comes to (simple) web applications, then most of the time Docker is a perfect fit. However, as you begin to migrate your applications into Docker containers, you might ask yourself how to forward all the requests to the different containers. A Docker Reverse Proxy can help!
While most Linux Kernels nowadays come with nice sysctl defaults, there’s always room for improvement. Some parameters can be used for performance tuning, others can be critical for security hardening. What is sysctl? sysctl is an interface to view and dynamically change parameters in Linux and other *NIX operating systems. In Linux, most of the dynamic Kernel settings can be […]
