Status Updates From The Algorithm Design Manual...

Should have read this book earlier - there are external references (to papers and codebases) which would have been of immense help.

One way to generate true random numbers is by taking external measurements (I use temperature and time). It may take longer than a few processor cycles per number. The overhead can be reduced by storing the numbers in memory (in an independent queue) for other programs to use.

Part one is usual, but part two seems to have new to offer. Seeking improvement. Easy to understand and practical.
