This script redefines the % motion so that (in addition to its usual behavior) it cycles through if/elif/else, try/except/catch, for/continue/break, and while/continue/break structures. The script also defines g% to cycle in the opposite direction. Two ot

Python anti-pitfalls The following are a quick (random, off the top of various heads) list of things that I think are anti-pitfalls in Python. That is, because the language has these features, it is harder to make programming mistakes.

Pypar -- parallel programming - 0 views
-
Pypar does not require the Python interpreter to be modified or recompiled: Parallel python programs use the standard Python and need merely import the pypar module. This means for example that you can upgrade Python independently of your parallel codes.
-
Pypar is an efficient but easy-to-use module that allows programs/scripts written in the Python programming language to run in parallel on multiple processors and communicate using message passing. Pypar provides bindings to an important subset of the message passing interface standard MPI. Other Python MPI bindings available from other developers include: PyMPI, Scientific Python and pythonMPI.

blog.bjrn.se: TrueCrypt explained - 0 views
-
he most popular cryptographic software for Windows is probably TrueCrypt. In this article I will explain how TrueCrypt works and as a by-product a working Python implementation will be provided. This article is written from a programmer perspective and the math will be kept to the minimum. The emphasis is on how TrueCrypt uses cryptographic primitives such as AES and SHA-1, not how the primitives themselves work.
