by Dave Peterson 15 Sep '08

15 Sep '08

I'm pleased to announce that the Enthought Tool Suite (ETS) 3.0.2 has just been tagged and released! Source distributions (.tar.gz) have been pushed to PyPi. Window's binaries will be built and uploaded to PyPi over the next 24 hours or so. You can update to ETS 3.0.2 like so: easy_install -U ets>=3.0.2 Changes ----------- ETS 3.0.2 is an update to ETS 3.0.1 that includes the following changes: * Update of Enable to fix problems doing 'setup.py install'. * Update of ETSProjectTools to fix bugs and improve the help messages. * Update of Mayavi to fix bugs found during the SciPy conference. * Update of Traits, TraitsGUI, and TraitsBackend* to fix a number of issues (see https://svn.enthought.com/enthought/query?milestone=Traits+3.0.2) What is ETS? ------------------ The Enthought Tool Suite (ETS) is a collection of components developed by Enthought and our partners, which we use every day to construct custom scientific applications. It includes a wide variety of components, including: * an extensible application framework * application building blocks * 2-D and 3-D graphics libraries * scientific and math libraries * developer tools The cornerstone on which these tools rest is the Traits package, which provides explicit type declarations in Python; its features include initialization, validation, delegation, notification, and visualization of typed attributes. More information is available for all these packages from the Enthought Tool Suite development home page: http://code.enthought.com/projects/tool-suite.php -- Dave

Hello, We're pleased to announce: OpenOpt v 0.19, free (license: BSD) optimization framework (written in Python language) with connections to lots of solvers (some are C- or Fortran-written) is released. Changes since previous release 0.18 (June 15, 2008): * Some changes for NLP/NSP solver ralg (especially related to handling linear constraints Ax <= b, Aeq x = beq, lb <= x <= ub) * Bugfix for ralg and IPOPT linear constraints handling * ALGENCAN v 2.0.x has been connected (v 1.0 is no longer supported, v 2.0.3 or later is required) * Bugfix for constrained NLSP graphic output (constrained nssolve isn't turned to latest ralg version yet) * Scale parameter for lpSolve (p.scale = {False} | True | 0 | 1) * New OO class LLAVP (linear least absolute values aka linear least deviations) * Improved handling of non-linear functions with restricted dom * GLP (global) solver galileo now can handle integer problems (via p.useInteger = 1 or True) * Another one GLP (global) solver connected: pswarm * Lots of work related to oofun concept (see OO Doc page for details) * Add converters llsp2nlp, llavp2nsp * Convenient handling of maximization problems (via p.goal = 'max' or 'maximum') * Some code clean up and bugfixes Backward incompatibility: * Changed objective function in LLSP * MATLAB-style gradtol renamed to gtol (for to provide same syntax to scipy.optimize fmin_bfgs, fmin_cg and less-to-type) Newsline: http://openopt.blogspot.com/ Homepage: http://scipy.org/scipy/scikits/wiki/OpenOpt Regards, OpenOpt developers.

Beginning Computer Programming with HLA and PYTHON
by dwzavitz＠gmail.com 14 Sep '08

14 Sep '08

Beginning Computer Programming with HLA and PYTHON will provide the beginner with a tremendous jump start in understanding. The newbie will readily appreciate the benefits of the High Level instructions in Python and HLA and the benefits of Low Level instructions in Assembly after just a little 'hands on' use of each. The reason for these free online Google Docs is to provide a fun and user friendly, but solid and quickly productive foundation for new programmers. And Python and HLA programs will work on today's most popular operating systems, so you will be well positioned with your programs for future customers. http://developers-heaven.net/forum/index.php/topic,46.msg83.html#msg83

RELEASED Python 2.6rc1
by Barry Warsaw 12 Sep '08

12 Sep '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team and the Python community, I am happy to announce the first release candidate for Python 2.6. This is a release candidate, so while it is not suitable for production environments, we strongly encourage you to download the release and test it on your software. We expect only critical bugs to be fixed between now and the final 2.6 release, still scheduled for October 1st, 2008. There is one more release candidate planned for September 17th. You might notice that unlike earlier releases, we are /not/ releasing Python 3.0rc1 at this time. It was decided that 3.0 still needs time to resolve open issues and that we would not hold up the 2.6 release for this. We feel that Python 2.6 is nearly ready for its final release. If you find things broken or incorrect, please submit bug reports at http://bugs.python.org For more information and downloadable distributions, see the Python 2.6 website: http://www.python.org/download/releases/2.6/ (Note that the Windows installers will be uploaded shortly.) See PEP 361 for release schedule details: http://www.python.org/dev/peps/pep-0361/ Enjoy, - -Barry Barry Warsaw barry(a)python.org Python 2.6/3.0 Release Manager (on behalf of the entire python-dev team) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQCVAwUBSMsXV3EjvBPtnXfVAQJFsgP9GxZYQocbDTd0Z/0yEjpHfZ/FTd8y83jV 5JouO07lB8XtLawnWB9hF8sUrCuBVog5He3mLVUPDmlyn30qvjYWMG2J6zW0yYMX yZdjUyUmta0IMCsXe7YXj369xebh4nWuwG4tDygly4donA7GYPXAlxI48MmyDJxw 1v07LM4Dttw= =Nd3s -----END PGP SIGNATURE-----

Py3K or Not at PyGTA Tuesday
by Mike C. Fletcher 11 Sep '08

11 Sep '08

It seems that Py3K (Python 3.0) is just around the corner, so let's discuss it. If you've played with converting your code to 3.0, are just toying with the idea, or have gone whole-hog and converted, bring your experiences to the table. A more general discussion of your strategies for migrating and maintaining code among different language/library versions should hopefully emerge. As usual, we'll be at Linux Caffe (corner of Grace and Harbord, 1 block South of Christie station), starting around 7pm and going until whenever on the Third Tuesday of the month. http://www.pygta.org/ Have fun all, Mike -- ________________________________________________ Mike C.

Greetings, I just wanted to alert everyone of the upcoming, 2nd annual, Python Texas Regional Unconference which will be held in Austin, TX this year. http://www.scipy.org/TXUncon2008 This site is a wiki page, so edit away! Like last year, this Unconference is intended to be a FREE event for Pythoneers from all over the Texas region to gather and share experiences and developments. Again, the topics to be presented are purely up to the participants. Last year there were two main tracks of talks: Python in Scientific Computing, and Python in Web Frameworks. We welcome any other presentations as well. Please see the schedule at the link above and add yourself to the list of attendees so we'll know you're coming. Please pass along this info to any other local meetup groups as appropriate.
