Occasionally, I get to find very interesting scientific apps for the Mac. In light of the recent events, SeisMac is definitely one of those. While not technically useful for the general public, it is a very important application for research. All Mac laptops include the so-called Sudden Motion Sensor, a Micromechanical system (MEMS) accelerometer. This [...]

I recently bought this 240 Gigabytes of awesomeness, conveniently packed into a 2.5″ SATA box. It’s an Other World Computing Mercury Extreme Solid State Hard Drive. It has no moving parts, it consumes less battery, and it’s fast. Damn fast. This thing is so fast it opens applications before you lift your finger from the [...]

Apparently, something changed in the ls command with the release of Leopard. I don’t remember seeing this kind of report on Tiger, although it looks like the features already existed since long time. Now, take this information with a grain of salt, as I am not a MacOSX expert, just a (very busy) occasional tinkerer [...]

Looks like I am not the only one suffering of keyboard freezes in MacOSX Leopard on a laptop. Looks like upgrading to 10.5.1 does not solve either. A temporary solution for this problem, while waiting for Apple to release a patch, is to keep numlock pressed for some seconds. When the led turns on, the [...]

I wrote the first part of some research I did on script relocatability. The basic problem is to make a script and its resources relocatable. It is not meant to be correct, actually I believe there are many errors and inaccuracies, but it brings a lot of arguments to discuss. I will write the second [...]
