Evil bugs in your code
by Kore Nordmann at Mon, 03 Dec 2007 15:31:05 +0100
From time to time I write some code snippets, which I find really hard to debug, and the code does not do, what it is expected to do. Especially when the code is not tested directly, but only executed in some a bit more complex environment. Those are 4 typical errors I introduced in my code, and spend some time debugging it, because I found them really hard to spot. Luckily, once I spotted the actual bug, I find it a lot easier the next time the typo occurs. Therefore I want to share those, so that I may save you some minutes of your life hunting stupid bugs. read more…

Tagging - Broken by design
by Kore Nordmann at Fri, 16 Nov 2007 11:46:11 +0100
In the meantime tagging, as a folksonomy, is often nearly used as equivalent to the whole Web-2.0-hype. Nowadays you can't develop any new application without adding tags, and I wanted to do the same. But reviewing the system in a bit more complex environment shows some major flaws, which can also be detected in the implementations of simple applications. This article lists some structural problems, and will be followed by other articles describing solutions for some of these cases. read more…

Why are you using BBCodes?
by Kore Nordmann at Mon, 03 Sep 2007 11:02:40 +0200
The discussion on my blog post "Do not use regular expressions for parsing" ended in a discussion about BBcodes in general. I just used them as an example to demonstrate why it it is impossible to parse such a language with regular expressions - and mentioned in a subclause, that I don't see any sense in using them at all. So why use them at all? read more…
