Image creation with PHP
There are several ways to create images or graphics with PHP. First there are some well known extensions, like ext/GD, or perhaps ext/ming everybody immediately remembers, when it comes to graphics generation. But there are several structural differences not in between the avaliable libraries, but also between the image formats you can create. This article series will give you some insight on the formats and libraries, and then shows how an abstraction layer could be build. This fifth part of the article covers the complex topic of text rendering with all the backends.

This third part of this article makes the images a bit more colorful, by providing support for gradients in the graphics.

Evil bugs in your code
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.

Tagging - Broken by design
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.
