xkcd widget

When I saw the xkcd comic “Now”, I immediately wanted it as widget on my smartphone. A cool little gadget showing you the approximate time of day all around the world.

I searched trough the Google Play Store and only found versions with a huge file size – since they just stored all possible images in the app files, the widgets reached a size of around 25 MB.

So I spent a few hours learning how to built Android widgets and compiled my own version – fewer than 1 MB big and with a cool preview animation.

Download the xkcd widget and try it for yourself!

Passdraw is my first smartphone app on Google Play.

Passdraw is a special keyboard assisting you with entering your passwords – which is normally ridiculously annoying on smartphones. After you have done the setup just draw one of your secret paths whenever you need your password!
+ No annoying switching between special characters and normal keyboard layout
+ Bystanders don’t get to see the original characters
+ This app does not know your password either
+ No extra permissions – your data stays with you!
+ No need for simple passwords
More information under www.passdraw.com or directly on Google Play.

Update (December ’13): I am currently working on a complete redesign with an entirely new algorithm and a new user interface. So stay tuned!

Hobson 2008

Hobson 2008 is a program suite which simplifies the selection of classes for German A levels. It replaces the current paper-based system by a web interface for the pupils and a management application for the school’s administration. Pupils can submit their course selection online while the administration is able to process the data and export them to third-party programs such as lecture-planning software.

Every 10th grader is assigned an account with which they can authenticate in the web interface to update their personal information whenever necessary, and finally make their course choices according to the limitations set by the Ministry of Education (the standard limitations are those of Rhineland-Palatinate).

The project was created as part of a school project and was developed together with Oliver Klupp. Those interested in the software can get an idea by downloading the (German) manual.

I need H.E.L.P

I need H.E.L.P. (High-End-Lautlos-PC – translates into High-End-Silent-PC) is a jump&run-game telling the story of a poor computer modder fighting against out-dated technology to reach his aim – the H.E.L.P. .

The game was created during a creativity competition managed by CHIP-Online. They assembled six different personal computers (a gaming pc, a home theater pc, …) and asked their community to apply for one of them in a creative way. I need H.E.L.P. was my application for the “Lautlos-PC” (a completely passive cooled and therefore almost soundless computer).
Accidentally I won this computer. My complete application (in German) can be found here. The game is compatible with Wine.
