In his short, highly-readable Turing Award speech, he describes "the cutest program I ever wrote." He notes that because the C compiler is written in C, it is possible to alter the source code maliciously to produce a malicious [...]

ACM Classics Wiki

I mentioned earlier that the ACM was asking for nominations for classic CS books. The nominations have been received and the ACM has set up a wiki for comments on the books. The intent is to come up with a list of out of print classics for republication.

ACM is launching a new initiative to revive classic, out-of-print, computer science books and make them available to members via the Professional Development Center and the Digital Library.

New, Efficient Sort Algorithm

This month’s issue of the Journal of the ACM presents an algorithm for in-place sorting which claims at worst O(n log n) comparisons and O(n) moves.

Safety First

From time to time folks see fit to publish lists of what the general priorities for developing a software project should be. The funny thing about these lists is that almost all of them omit what I consider to be the number one priority….
