As you might have noticed, posting frequency has waned over recent years which is partly to do with Real Life taking over somewhat but also because my professional life...

The MATLAB community site, MATLAB Central, is celebrating its 20th anniversary with a coding competition where the only aim is to make an interesting image with under 280 characters of code. The 280 character limit ensures that the resulting code is tweetable.  There are a couple of things I really like about the format of this competition, other than...

Just over 4 years ago I was very happy with the 1.2 Teraflops of single precision performance I measured on my then-new Dell XPS 95600 laptop using MATLAB’s GPU Bench and noted that its performance was on-par with the first supercomputer I supported professionally. Double precision performance stank of course but I had gotten used to that with laptop...

Simultaneously, The Numerical Algorithms Group announced that they had ported their Fortran Compiler to the new platform. At the time of writing this is the only Fortran compiler publicly...
