This blog (“Walking randomly”) contains a pretty host of good pieces in computational programming, in Matlab, Python, R, etc, and also of news about computational software, particularly open-source tools, and mathematics by large.

Several that are of interest to most (after a very random walk of recent entries):

Randomness in Matlab (discussing why using the new random generator controller

**rng()**is important, here also)Pandas toolbox (Python data analysis package frequently mentioned in the blog)

The Julia language (A new high-level language targeted for high-performance with the slightest coding pain)

Disagreement on operator precedence for 2

^{3}4 (Don’t be afraid to use brackets!)Nonlinear eigenvalue problems and a toolbox (Solving problem of the form \(F(\lambda) \mathbf{ x} = 0\) where \(F\) maps complex scalars to complex matrices (e.g., matrix-coefficient polynomials). Applications can be found in many minimal problems in computer vision, e.g., the relative pose problem.

Will 2012 be the year when OpenCL adoption really takes off? (Describing trends in CPU-contained GPU units and relative lack in OpenCL’s stand in scientific computing arena)
