[ANN] Websourcebrowser 0.4a released
by Stefan Schwarzer Aug. 4, 2010

Aug. 4, 2010

Hello, I'm happy to announce the release of Websourcebrowser 0.4a. Websourcebrowser is a program intended to get a quick overview of a project's source code. The program is controlled from a web browser which displays a directory tree and a source code file side by side. The homepage of the project is at http://websourcebrowser.sschwarzer.net/ The download of version 0.4a is at http://websourcebrowser.sschwarzer.net/download *** Note that this is still an alpha release. *** I use the program regularly to dive into new projects, but I consider it in the alpha stage because it has been used and tested by only a few other people than me. On Windows, this version doesn't seem to work with IE 8.0 whereas it works with Firefox 3.6.8. I know the software could be improved a lot. For some ideas, look at http://websourcebrowser.sschwarzer.net/trac/wiki/Ideas http://websourcebrowser.sschwarzer.net/trac/browser/todo.txt If I implement this alone, it'll probably take years, given that Websourcebrowser is a spare time project (beside my other project, ftputil). So it would be great to get more developers on board. Of course, I'm thankful for feedback on the mailing list (subscription required to avoid spam, sorry), http://codespeak.net/mailman/listinfo/websourcebrowser or via private e-mail. If you encounter problems, you may also file a bug report at http://websourcebrowser.sschwarzer.net/trac/newticket *** You need to log in as user wsbuser with password wsb . *** Stefan

ANN: Numexpr 1.4 released
by Francesc Alted Aug. 1, 2010

Aug. 1, 2010

======================== Announcing Numexpr 1.4 ======================== Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. What's new ========== The main improvement in this version is the support for multi-threading in pure C. Threading in C provides the best performance in nowadays multi-core machines. In addition, this avoids the GIL that hampers performance in many Python apps. Just to wet your appetite, look into this page where the implementation is briefly described and where some benchmarks are shown: http://code.google.com/p/numexpr/wiki/MultiThreadVM In case you want to know more in detail what has changed in this version, see: http://code.google.com/p/numexpr/wiki/ReleaseNotes or have a look at RELEASE_NOTES.txt in the tarball. Where I can find Numexpr? ========================= The project is hosted at Google code in: http://code.google.com/p/numexpr/ And you can get the packages from PyPI as well: http://pypi.python.org/pypi Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy! -- Francesc Alted

[RELEASED] Python 3.2 alpha 1
by Georg Brandl Aug. 1, 2010

Aug. 1, 2010

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I'm happy to announce the first alpha preview release of Python 3.2. Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only. Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python's syntax and built-in types in Python 3.2. Development efforts concentrated on the standard library and support for porting code to Python 3. Highlights are: * numerous improvements to the unittest module * PEP 3147, support for .pyc repository directories * an overhauled GIL implementation that reduces contention * many consistency and behavior fixes for numeric operations * countless fixes regarding string/unicode issues; among them full support for a bytes environment (filenames, environment variables) * a sysconfig module to access configuration information * a pure-Python implementation of the datetime module * additions to the shutil module, among them archive file support * improvements to pdb, the Python debugger For an extensive list of changes in 3.2, see Misc/NEWS in the Python distribution. To download Python 3.2 visit: http://www.python.org/download/releases/3.2/ 3.2 documentation can be found at: http://docs.python.org/3.2/ Please consider trying Python 3.2 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy! - -- Georg Brandl, Release Manager georg at python.org (on behalf of the entire python-dev team and 3.2's contributors) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (GNU/Linux) iEYEARECAAYFAkxVQJsACgkQN9GcIYhpnLBxIgCcCiVu/QUkFf0bYM2Vmi8St3mZ 2N4An04q36lr47OA+bslqG/4Zj7ZwVOX =iL8N -----END PGP SIGNATURE-----
