P.S. The picture is a Beta-prime distribution. It shows the program speedup factors you can get if you see a problem twice in 2, 3, 4, and 5 samples.

+ That's what callbacks are good for, but I hate having to write them :-)

comment Implicit optimization versus explicit optimization
+ Library routines should not be sluggards, but their main purpose is ease of use, correctness, and reliability. I discovered using LAPACK that it was actually not very efficient in the case of small matrices, but it still serves its purpose.

comment What to do when your colleagues don't value code maintainability
I saw things like that during my contracting days. It seems to me the real problem is the high turnover, and that is caused by a management style, starting from the top, that doesn't actually value its people. I could always tell, just by sizing up the CEO, whether this would be a good company to work for.
