This is actually just a copy of an article from ubuntu.com, but they tend to move things around and I like to have short search times. Apart from that, this works for FreeBSD and even for Windows (tested with Windows 7) as well. Sorry for this this blatant plagiarism, but it might be also to your advantage ;)

One more note: If you want to create a bootable USB stick to be used on a Mac/OS X, do not forget to format the stick with Disk Utility to HFS+ with a GUID partition table.

I just cleaned up my home brew cellar and had problems reinstalling R. I got the old well-known error message:

brew install r
==> Downloading http://cran.r-project.org/src/base/R-2/R-2.15.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/r-2.15.1.tar.gz
Error: This formula requires a fortran compiler,...

Reinstalling gfortran (which was actually installed already) did not help and so I decided to trick home brew until the problem is fixed, with the following:

What a nice post on Stackoverflow! Just paste the following lines into your .ssh/config file and let SSH redirect to ssh.github.com

After I had to upgrade the X11 support on OS X 10.8 (Mountain Lion), I got an annoying dialog asking for some strange application called OroborOSX every time I wanted to start Matlab. After a quick look into the launch script, I found a solution and it seems to be aligned with Mathworks - the company behind Matlab.

I just added a workaround for DAViCal with Apple’s Address Book application. Since my update to 10.7.4, I was no longer able to add a contact to the server and the card stopped the whole server communication to fail completely.

This is a (growing) collection of useful custom settings for the PostBox mail client. It obsoletes the old post for one PostBox setting. All these settings are available in the PostBox configuration editor, which is located under Preferences -> Advanced -> General -> Config Editor...

As written in a post before, I customized the Drupal RSS feed icon by replacing it with my own PNG icon. Unfortunately, the PNG icon should be designed well and is never scalable when using pixels. Therefore, I wanted to change it to a font based (vector) icon using again free fonts from font squirrel.

I just added a page to my Mailserver documentation. I finally found the time to setup per user spam filtering for all accounts just based on the contents of a folder. Very easy to use for everybody indeed.

I hope you’ll enjoy reading :) Cheers, iss

Yesterday evening I decided to move from dynamic http/https switching to SSL (https) only mode. I decided to do so because I want everybody to feel free to take down her tin foil hats when visiting my site.

Some weeks ago I had to run a simulation for my research which has been very elaborate and involved externally invoked scripts on remote machines (so-called Wuchtbrummen). These external calls were dispatched by a central main script, that was running on my local PC. To avoid a complete SSH session setup and teardown every time a new call should be invoked on a Wuchtbrumme, I wanted to have a persistent SSH connection, where all subsequent commands can be tunneled through.
