(In fact it's an implementation of the sieve of Eratosthenes). The bugs came not only from not beeing interested in primes less than 2 ;-) but also from beeing a little tired already. Sorry. I think the following version repairs that - and hopefully uses less obfuscating variable names (which in fact originally was part of the "riddle"): def primes(n): sieve, zeros = range(n), [0]*n sieve[:2]= 0,0 i = 1 while i*i < n: if sieve[i]: sieve[i*i:n:i]=zeros[i*i:n:i] i += 1 return [p for p in sieve if p] Regards, Gregor >

But there are half a million players now, so how to get your issue made into one that the every nation must vote on (or ignore) is complicated. I haven't figured it out yet. Laura

FW: Common Live CD base and generator (was: Educational Collaboration)
by Arthur Feb. 22, 2004

Feb. 22, 2004

The ideas for LiveCD creation for educational use are peculating. The concept presented here I think is good indication of the good things to come.

The idea I would like a litle more would be a project to include a live CD base package into debian. Maybe with support from Morphix and others. A Debian Live CD generator, somthing like jigdo[1] for live CDs that can draw any .deb into a live CD. Peter [1] http://www.debian.org/CD/jigdo-cd/

You try to shoot yourself in the foot, only to realize that there's no need, since Guido thoughtfully shot you in the foot years ago.

Groovy
by Jason Cunliffe Feb. 17, 2004

Feb. 17, 2004

http://groovy.codehaus.org/ "Groovy is a powerful new high level dynamic language for the JVM combining lots of great features from languages like Python, Ruby and Smalltalk and making them available to the Java developers using a Java-like syntax. Groovy is designed to help you get things done on the Java platform in a quicker, more concise and fun way - bringing the power of Python and Ruby inside the Java platform. Groovy can be used as an alternative compiler to javac to generate standard Java bytecode to be used by any Java project or it can be used dynamically as an alternative language such as for writing scripts or unit test cases.
