Open Source Conference

I just came across Matt Raible's report on the OSCON'08.

A couple of tidbits from that post:

IT jobs are 2.3% of all jobs posted, according to the Bureau of Labor Statistics. Technology oriented companies (e.g., Google, Yahoo, Sun) make heavy use of Open Source (40% of all jobs posted by Y!). Open source is growing faster in non-tech companies. Of the open source technologies in the enterprise, the highest share of jobs is… Continue

Laws of data driven decision making

I came across a wonderful, somewhat tongue in cheek, posting by Edmund Freeman here. Anyone that has been asked to do an analysis to support decision making will recognize these principles. Here they go:

Certainty Principle: Certainty is inversely proportional to knowledge
Anyone that works with data will understand the limitations of data and any inference analysis or signal processing. When maki… Continue

Computational Science and Engineering book

I was looking for a classification of algorithms used in Computational Science and Engineering for Stillwater's trifecta. In all classification problems, selecting the right attributes is key. I was on the wrong path since I was trying to use a classification based on solver algorithm structure and that caused significant problems since it appears to cause a decoupling of the physical intuition of the original problems. So I started to look for others who have attempted to construct a structure… Continue

Climate Prediction

While researching climate models I came across a BOINC based community for climate prediction: climateprediction.net at http://www.climateprediction.net

From their website:

The aim of climateprediction.net is to investigate the approximations that have to be made in state-of-the-art climate models. By running the model thousands of times (a 'large ensemble') we hope to find out how the model responds to slight tweaks to these approximations - slight enough to not make the approximations any le… Continue
