# > How about thinking up new algorithms that run an order of magnitude faster # > than the one you first thought of? that's what kernighan and plaugher had to say in their classic "the elements of programming style" (2nd ed, 1978). http://www.amazon.com/exec/obidos/tg/detail/-/0070342075/qid=1126976107/sr=8-3/ref=sr_8_xs_ap_i1_xgl14/104-2565701-7342352?v=glance&s=books&n=507846 though the examples were mostly in fortran, the concepts are timeless. for $11.50 (used, from amazon), it's a hell of a deal for anyone here who hasn't got a copy. # yep! Bram Cohen's BitTorrent is a good example. A pure networking # algorithm, written in Python -- an interpreted language. But still a # significant improvement on traditional TCP/IP transfers in certain aspects. network applications will almost always be network-performance limited. python or perl or other scripting MIGHT slow down a number crunching app that had no network or filesystem dependencies, but even in that case it's likely that (a) some use or misuse of the scripting language's special features will make reasonable performance possible, and (b) by the time moore's law works its magic, you'll have saved more time from being able to debug the app and execute more-working code than you'll have lost from whatever extra cpu cycles you spent. _______________________________________________ Fun and Misc security discussion for OT posts. https://linuxbox.org/cgi-bin/mailman/listinfo/funsec Note: funsec is a public and open mailing list.
