Displaying log data in latest-first format
I like having log data in a last-first form (the same way most blogs and news sites organize their posts). The languages I'm most comfortable in are C++ and Python: is there a way to output log data either to the screen (stdout) or a file with the most recent entry always being on top? Or is there perhaps a way of modifying tail to sho...

Reordering python list based on an algorithm or pattern
Here is a stumper for you math geeks out there. I have a python list that is just a sequence that looks like this: myList=[1,2,3,4,5,6,7,8,9,10,11,12,13,(...etc...),43] Unfortunately, the data from which the list was generated was not zero-padded, and it should have been. So in reality: 1==1 2==10 3==11 4==12 5==13 6==14 7==15 8=...

Metrics on "market share" for server-side scripting languages
Hi all, Does anyone know of any market share information for server-side scripting languages (# of web servers, % of web servers, etc.)?
