Gestion de versions: la gestion des sources de python passe de subversion à mercurial !.
- http://sayspy.blogspot.com/2009/03/why-python-is-switching-to-mercurial.html (‘Starting at PyCon 2008 thanks to Barry Warsaw and the Bazaar team I started thinking about moving Python over to a distributed version control system (DVCS). While I wanted to get offline commits for the benefit of non-core developers along with easier merging from 2.6 to 3.0 (ah, the days when there are only three branches under development), I knew that would not necessarily be enough of a reason for others to switch…Based on the results of that survey where git was clearly the most disliked tool of the core developers, having the weakest Windows support, and not being implemented in Python, I decided to eliminate git from the running and announce its elimination at the first lightning talk at PyCon.When I arrived at PyCon pretty much everyone asked me about the DVCS PEP. People wanted to know how it was going, who was going to win, and giving me support/pity for what I was going through. Guido noticed this and decided to end my misery by saying he wanted to make a decision by the end of PyCon. I said I was fine with that as one was already about to be eliminated and I knew my personal preference at that exact moment aligned with Guido’s…So Monday morning came around and I walked into the sprint. I asked Guido if he was ready to make a decision. He said yes, we both said hg, and so Guido tweeted the decision before telling python-dev that we chose Mercurial…Obviously community preference as shown at PyCon played a role. No one wants to choose a DVCS that causes the community to not want to contribute to Python. And I would never choose a VCS that would cause Guido to not want to work on Python. Some people seem surprised that something non-technical played a role, but ignoring social issues is to ignore how much open source is a social phenomenon. And we are not the first project to take social preference into consideration: I know both GNOME and Pinax chose git because their developers preferred git. And there are technical reasons. Having hg being faster than bzr by 2x to 3x does matter to some extent. No one wants to cause someone to not contribute because they didn’t want to wait for a checkout. And having personally experienced long checkout times because of a subpar connection to a specific server I know this can occur. The performance margin between hg and bzr is within reason typically and is not a flat-out deal-breaker, but it doesn’t help either. Bazaar also has its short timespan of format stability working against it. The tool has changed its format at least three times based on what the man page says (1.0, 1.6, and 1.9). Mercurial, on the other hand, has been stable since I think it went public or near that time. They take great pride in the fact they have not changed it. And that stability more aligns with python-dev’s sensibilities regarding stability. Once again the Python community stands out as being friendly and understanding about stuff like this with no one really seeming to be upset that we made the decision we did.’)

- http://en.wikipedia.org/wiki/Mercurial_(software) (‘ Mercurial is a cross-platform, distributed revision control tool for software developers. It is mainly implemented using the Python programming language, but includes a binary diff implementation written in C. Mercurial was initially written to run on Linux. It has been ported to Windows, Mac OS X, and most other Unix-like systems. Mercurial is primarily a command line program. All of Mercurial’s operations are invoked as keyword options to its driver program hg, a reference to the chemical symbol of the element mercury. Mercurial’s major design goals include high performance and scalability, decentralized, fully distributed collaborative development, robust handling of both plain text and binary files, and advanced branching and merging capabilities, while remaining conceptually simple . It includes an integrated web interface.The creator and lead developer of Mercurial is Matt Mackall. The source code is available under the terms of the GNU General Public License version 2, qualifying Mercurial as free software.’)

At the time of this post about 14 talks are now online. By the end of the day Friday, almost everything should be available (with a few minor exceptions). The videos are also integrated into the PyCon Schedule App as well, with a minor lag time. Just look for the tiny video icon: .
Congratulations to the entire PyCon US 2009 volunteer video team for performing this Herculean task. In total 2.2TB of video, covering 168 hours of material, were collected, edited, transcoded, and uploaded. This is divided into 96 hours from the tutorials and 72 hours from the main conference.’)

If I’d had $1 million of startup funding to hire a staff to work on sqlpython, I couldn’t have gotten a team that large or that talented. I figure that gives me better than a 1000-to-1 return on my PyCon investment. :) ‘)
Python 3.1a2 release
- http://mail.python.org/pipermail/python-dev/2009-April/088213.html (‘ On behalf of the Python development team, I’m thrilled to announce the second alpha release of Python 3.1. Python 3.1 focuses on the stabilization and optimization of features and changes Python 3.0 introduced. For example, the new I/O system has been rewritten in C for speed. Other features include an ordered dictionary implementation and support for ttk Tile in Tkinter. For a more extensive list of changes in 3.1, see http://doc.python.org/dev/py3k/whatsnew/3.1.html or Misc/NEWS in the Python distribution.Please note that this is an alpha release, and as such is not suitable for production environments. We continue to strive for a high degree of quality ,but there are still some known problems and the feature sets have not been finalized. This alpha is being released to solicit feedback and hopefully discover bugs, as well as allowing you to determine how changes in 3.1 might impact you. If you find things broken or incorrect, please submit a bug report at http://bugs.python.org. For more information and downloadable distributions, see the Python 3.1 website:
