ffmpeg 0.5 for OS X

The original VholdR wearable camcorder, a tiny solid state camcorder that easily mounts to helmets, bikes, dogs and whatever else to capture POV video, is a good little package. For Mac users, the output format of this camcorder can be a problem to manipulate without lots of tweaking. The ffmpeg utility makes using these files, in their original state, easy on the Mac.

Broken Spokes From Surface Rust

When building your own wheels -- or anything -- ensuring you have quality parts is paramount. I've built many wheels now and usually use DT Swiss spokes, but for my custom trike project, the spoke vendor wasn't known. And it had disastrous results.

Last year my recumbent trike (link in progress) developed a case of Spokus Brokenus on one of its front wheels. It's a "tadpole" trike, which means there is one wheel in back for propulsion, and the two in front steer. It was odd that just the one front wheel had this issue, but it became clear why.

XCode 3.0 Copy Files dependency bug

One of our builds was breaking recently, and the error messages reported from Xcode 3.0's xcodebuild command were unusual. Xcode 3.0 has broken dependency handling, at least in one case.

Sharing shared libraries on OS X

Recently at work I encountered a problem with dylibs (shared libraries) with our OS X application. Our application is based on a cross-platform modular framework that runs on four different platforms, and the modular plugin architecture makes it easy to include new features into our programs.

New website engine for Relro

Finally! After trying a few different CMS configurations I've finally decided on Drupal. A couple years ago I tried Joomla but found it cumbersome with difficult theming, and more recently I tried Django which was very cool if I wanted to write a CMS but not what I wanted on this site.

Drupal has a great balance, and a good abstraction between content and theming. Its community is very active in terms of development as well as supporting new users, so its a good thing.

EvoLisa in C++ and OpenGL

Last December Roger Alsing had an interesting blog entry that created an approximation of the Mona Lisa with genetic programming in a program named EvoLisa. I'm not familiar with genetic programming techniques, but given the application to graphics I was interested.
