  • ...lists, and to the PSF blog (http://pyfound.blogspot.com/2006/12/call-for-nominations-of-psf-directors.html). We had a good response, with 4 new candidates stepping forward, in addition to the 8 incumbents. We have a total of 12 candidates for Director this year, but currently the Board is limited to 8 Directors. As Tim Peters put it, "the bigger the board, the more gets done." This motion aims to increase the limit on the number of Directors going forward. We learned in the past that...

  • Python Success Stories

    Python Success Stories Background The Molecular Modeling Toolkit (MMTK) is a open source Python library for molecular modeling and simulation with a focus on biomolecular systems, written in a mixture of Python and C. It provides standard techniques such as Molecular Dynamics or normal mode calculations in a ready-to-use form, but also provides a basis of low-level operations on top of which new techniques can easily be implemented. I started developing MMTK in 1996. I had some experience wit...

  • Bugs in Python 2.3.1

    Bugs in Python 2.3.1 <h3>Bugs in Python 2.3.1</h3> <ul> <li>IDLE now executes code in a separate process. To communicate between the main process and executing processes, IDLE opens a socket to 127.0.0.1 (the local machine). Some firewalls running on Windows machines interfere with this and can cause either silent failures or erroneous popup windows from the firewall. This problem only occurs if you run a firewall on the same machine as IDLE.</li> <li>The...

    ...lists than the previous implementation, and reported to be just as fast on randomly ordered lists on several major platforms. This sort is also stable (if A==B and A precedes B in the list at the start, A precedes B after the sort too), although the language definition does not guarantee stability. A potential drawback is that list.sort() may require temp space of len(list)*2 bytes (*4 on a 64-bit machine). It's therefore possible for list.sort() to raise MemoryError now, even if a comparison...

    ...lists of properties that define each unique custom ERP implementation. This has reduced maintenance costs by an order of magnitude: The typical ERP5 system contains 100,000 lines of code, rather than the 1,000,000 lines of code required in similar projects based on traditional programming techniques. Python supports efficient metaprogramming through powerful introspection features that allow programs to inspect and modify code at runtime. Java's introspection are by contrast quite poor and infle...
