How to patch binary files with Java
Recently, I wanted to create an “intelligent” binary patcher, which not only replaces some chunk of binary data at a file’s predefined offset, but instead performs search and replace. Here is the Java class I came up with. import java.io.*; import java.math.BigInteger; public class BinaryPatcher { private String content; private final String filename; private final [...]
Robust HTML parsing the Groovy way
With Groovy, it’s very easy to parse XML data and extract arbitrary information. This works great as long as the input data is well-formed, but you can’t always guarantee that in real-world scenarios. Think of extracting data from HTML pages. They are very often a mess when it comes to XML validity and that’s where [...]

Logitech G5 Laser mouse on Mac OS X (updated)
I recently bought Logitech’s G5 Laser mouse. It’s meant to be a gamer mouse but is also great for daily work. The only problem for us OSX users is that Logitech in contrast to most of its devices doesn’t offer drivers. The mouse works just fine out of the box without any proprietary driver, but [...]
My Top 3 Finder Toolbar Scripts
With Leopard’s Finder, you can not only add applications to the toolbar, but also scripts. That’s an extremely useful feature I use every day and so I put together an introduction to my favorite three. But let’s first talk about the installation. That’s pretty easy. Just extract the downloaded archive, copy the script to an [...]
