Its features can be handy: you can safely deliver banking information via e-mail when using GPG or verify the authenticity of the sender of a message. I wil describe the basic setup for a GPG key, GPG configuration and GPG key signing. ...

accessibility in Android

Posted by Sebastian Humenda at 15/09/2013 (12:29)

Finally I got my hands on a Samsung smartphone and tried out the accessibility provided with Talkback on an Android 4.2.2. I want to give a short overview what is already working and what not. Fortunately, I cannot (and don't want!) compare the accessibility to the other big mobile operating system which has currently accessibility features. ...

Encodings In CGI Scripts Using Python3

Posted by Sebastian Humenda at 12/09/2013 (13:17)

As some might have noticed, I have rewritten my internal blog handling to make the appearance more uniform with the general web site design and to allow comments in the future. Since I now have switched „full-time” to Python 3.x, I had some real problems with encodings in Python3-CGI scripts, which I here want to discuss. ...

uTeXer: replace (math) Unicode

Posted by Sebastian Humenda at 04/08/2013 (18:31)

When I am reading scientific papers or technical books, I'm often stumbling over formulas. Since I'm using a screen reader, I can't read (in most cases) the Unicode signs and therefore they must be corrected (transcribed into LaTeX commands) by someone else. Another annoying thing are the ligatures produced by LaTeX, found in a lot of PDF's, because they can't be read by speech synthesizers. ...

Chroot At Boot Time

Posted by Sebastian Humenda at 04/07/2013 (13:41)

I wanted to experiment with more up-to-date software while preserving my stable working environment. Of course a frequent desire. Therefore I build a Debian unstable chroot and tried to get X running. But I didn't want to run chroot manually. In this article, I want to show you how I start my chroot with X support at log-in-time on a separate console. It should be mentioned that other tutorials already discuss this topic, but they didn't work for me. ...

There happened quite a few things in Debian, especially because Wheezy will be released soon. At this point a short overview about activities from me or about things which I've translated in the Wiki and are noteworthy to mention. ...

scanning and recognizing text on the console

Posted by Sebastian Humenda at 02/04/2013 (12:30)

The usual problem seems to be that there are a lot of tools which do the job, but the available front ends don't fulfil the personal requirements. Look at the current scanning front ends: ...

virtualisation with braille and speech

Posted by Sebastian Humenda at 30/03/2013 (19:02)

I always translate the Debian wiki page into German. That's not as boring as some might think because this way I keep track of what happens in regard of accessibility in free software or Debian respectively. ...

Own Radio Stream With Icecast

Posted by Sebastian Humenda at 26/12/2012 (17:08)

I like to listen my music everywhere where I want:wq , not only at the computer . My smart phone has not enough space for all my music and anyway, I don't like to keep the music on my notebooks and my smart phone synchronized. Therefore a own streaming server is the easiest solution. I'll describe here a quick setup which assumes Debian GNU/Linux (or Ubuntu), but can be done on other *nixes as well. ...

Tunneling Ports behind NAT over SSH

Posted by Sebastian Humenda at 26/12/2012 (12:08)

It can be useful to make a service from your machine available for others, might it be a http server, a game server or even a icecast streaming server. Unfortunately the pain called NAT can prohibit that sometimes. The simple solution is to forward the port from your local machine to a server. The problem I had was that most sources in the internet explain how to forward a port from a host to the local computer by binding the port on this local machine. The fastest way for tunneling is in my opinion to tunnel over SSH, since it has already all facilities for this task. Throughout this article I'll use the term host for referring to the server which will tunnel the port out of the NAT. ...
