easiest way to split a list into evenly divisble smaller lists, and assign them to variables?

Lets say I have a list containing 12, 13, 23 or however many entries. What I want is the greatest number of lists evenly divisible by a certain number, and for those lists to be assigned to variables. This leads to a few problems.. If I don't know the length of the list beforehand, I can't create

Re: Grand Challenge Pegasus Team: Programming Pegasus Bridge 1 ?

Thank you Alex for your feedback. What I am really proposing is for others to test their software on our vehicle for the very reason that there are a lot of unknowns that I cannot believe can directly modeled into an ODE type of engine (as you call it.) Several reasons for this: - one piece of d

Re: Socket Speed

300KB/s sounds dreadfully low. I simply ran "python /usr/lib/python2.3/SimpleHTTPServer.py &", then "wget -O /dev/null http://0.0.0.0:8000/70megfile";. On the best of 4 runs (when the file was cached) wget measured 225.20MB/s. The hardware is a Pentium-M laptop with 768MB RAM runnng at 1.5GHz.
