GPULib pre-release

A pre-release of GPULib was made available today. GPULib is a library of common scientific computational routines that use modern graphics processing units (GPUs) to improve performance. I saw speedups of 5-50 times faster than normal IDL code for example code I was writing. Vectorized code that is still not fast enough can be improved […]

I would like to eventually write this as a DLM, but until then here’s my pure IDL draft. It contains a main-level […]

Google charting API

Google released a seriously cool charting API today. The data and options about its presentation (not as many as IDL, but quite a few) are encoded into the URL of the image. Of course, there are plenty of chartjunk options, but it seems quite possible to make some serviceable graphs. The one thing I wasn’t […]

Pictures of Numbers blog

I recently discovered Mike Dickison’s Pictures of Numbers blog. He keeps the quality very high (posting only when he has a polished article, averaging just over one post per month for the last two years).
