  • Python Software Foundation: Minutes of Board of Directors Meeting (July 12, 2005)

    ...releases should be a "PSF product". If yes, the PSF members should be asked if they agree. For the PSF, the advantage would be better visibility. Anthony Baxter is Python's all-purpose release manager, with a time plan that he tends to follow. T. Peters asked what a Python release committee would do that Anthony isn't already doing. M. von Löwis said that Anthony should be asked whether he wants to chair such a committee. A discussion ensued, touching on the following issues: This...

  • Ancient Releases

    ...Releases Andrew Dalke was clever and persistent enough to scrape Python 0.9.1 out of the Usenet alt.sources archives and assemble a compressed tarball. It's here mostly as a historical relic. If you want a compiled binary (on Linux) you can install it with conda (ideally in its own conda environment): conda install -c davidmertz python=0.9 Skip Montanaro has created a GitHub repository of Python 0.9.1 source.

  • Python Success Stories

    Python Success Stories Background MayaVi is an open source scientific data visualization tool written entirely in Python. I started work on MayaVi in 2000. At that time, a few colleagues of mine needed to visualize their computational fluid dynamics (CFD) data but the only suitable tools available were commercial, closed source programs that were prohibitively expensive. We looked at some open source tools as alternatives. OpenDX had just been released to the public and at that time was har...

To communicate between the main process and executing processes, IDLE opens a socket to 127.0.0.1 (the local machine).

The new seed function addresses two problems: (1) The old function couldn't produce more than about 2**24 distinct internal states; the new one about 2**45 (the best that can be done in the Wichmann-Hill generator). (2) The old function sometimes produced identical internal states when passed distinct integers, and there was no simple way to predict when that would happen; the new one guarantees to produce distinct internal states for all arguments i...
