I'm a great fan of the TV series Game of Thrones and the books it's based on.

Be aware, you need a braille printer or similar device to produce tactile maps.

For the friends of the text console I've created a small shell script, which extracts text from images and scanned PDF files. You can specify as many input files as you want. The results are merged into a single text file. You can open it in your favorite text editor or pipe it to stdout. The program Tesseract is used for the text recognition.
Calendars and address books contain very sensible personal data. So it's not advisable to share them with companies like Google or Apple. But with more than one client system in use, it is necessary to run an own calendar server to synchronize that data between the clients.
The first part of this article describes the installation and configuration of a calendar and contacts server. After that follows the presentation of calendar and address book programs for the Linux console and the Android operating system.
Last year I've converted my blog to Octopress, a static website generator. Although I appreciate the general advantages of a static website generator I miss two features now:
Octopress doesn't support multilingual websites
It's mainly for blog's. Other website layouts are difficult to realize.
The layout adaption would be fairly time consuming. So I searched for an alternative website generator which allows a more flexible design. I found what I searched for at nanoc. This article contains the created nanoc theme for this website.
