Visiting Seoul, Korea

Today I arrived in Seoul, South Korea. I am here for a four weeks research stay at the HCI lab of the Konkuk University together with Nadia, a colleague of mine.

Clean Code: Comments about some ”smells“

In the last article I introduced the highly recommendable book ”Clean Code“ written by Robert C. Martin. While I tried to essentially describe what the book is about and what’s so great about it, I would like to comment on some of his so-called ”code smells“. I do not want to challenge the quality of [...]

Printing from Mac OS X to Ubuntu 10.04

When I just wanted to install the shared network printer on my wife’s new MacBook Pro, I was pretty much at a loss. The printer just didn’t want to show up in the list of available printers, even though I can see and use it without any problems from my laptop (also a MacBook Pro). [...]

Contrasehen – Die 2. Staffel

Seit dem 10. Juni 2009 läuft jeden zweiten Donnerstag wieder eine neue Folge der etwas skurrilen Internetshow Contrasehen. Nachdem die erste Staffel mit ihren 40 Folgen zunächst sehr strukturiert begann, dann aber das Konzept verloren ging und die Sendung im Chaos unterzugehen drohte, macht die aktuell laufende zweite Staffel nun Nägel mit Köpfen und verfolgt [...]

The Stack Overflow Questions Widget

There is news: a plugin for WordPress which displays questions you have asked on Stack Overflow in a small widget in your blog.
