ANN: NumPy 1.0.4
by Jarrod Millman 07 Nov '07

07 Nov '07

I'm pleased to announce the release of NumPy 1.0.4. NumPy is the fundamental package needed for scientific computing with Python. It contains: * a powerful N-dimensional array object * sophisticated (broadcasting) functions * basic linear algebra functions * basic Fourier transforms * sophisticated random number capabilities * tools for integrating Fortran code. Besides it's obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide-variety of databases. This is largely a bug fix release with one notable improvement: * The NumPy and SciPy developers have decided to adopt the Python naming convention for classes. So as of this release, TestCase classes may now be prefixed with either 'test' or 'Test'. This will allow us to write TestCase classes using the CapCase words, while still accepting the old style names. For information, please see the release notes: http://sourceforge.net/project/shownotes.php?release_id=552568&group_id=1369 Thank you to everybody who contributed to the recent release. Enjoy, -- Jarrod Millman Computational Infrastructure for Research Labs 10 Giannini Hall, UC Berkeley phone: 510.643.4014 http://cirl.berkeley.edu/

[ANN] Release 0.66.1 of Task Coach
by Frank Niessink 07 Nov '07

07 Nov '07

Hi, I'm happy to announce release 0.66.1 of Task Coach. This bug fix release addresses four bugs: * When changing the sort order in a tree viewer, keep collapsed items collapsed and expanded items expanded. * Sort categories alphabetically in task editor. * Double clicking a task in the tree view did not open the task edit dialog. * When filtering on a specific category, a newly added task belonging to that category was not shown in the task viewers. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org In addition to the source distribution, packaged distributions are available for Windows XP/Vista, Mac OSX, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

New book: Object-Oriented Programming in Python
by Michael H. Goldwasser 06 Nov '07

06 Nov '07

We are pleased to announce the release of a new Python book. Object-Oriented Programming in Python by Michael H. Goldwasser and David Letscher Prentice Hall, 2008 (available as of 10/29/2007) This book is based on materials developed after switching our curriculum to the use of Python for an object-oriented CS1 course. Since the primary market is an introductory course, we do not assume any previous programming experience for our readers. This should make it a very good match for those who wish to self-study. The book differs greatly from existing introductory Python books as it warmly embraces the object-oriented nature of Python from the onset. It is also extremely comprehensive with solid fundamentals as well as several "advanced" topics that can be covered as desired. More information can be found at http://www.prenhall.com/goldwasser With regard, Michael Goldwasser +-----------------------------------------------+ | Michael Goldwasser | | Associate Professor | | Dept. Mathematics and Computer Science | | Saint Louis University | | 220 North Grand Blvd. | | St. Louis, MO 63103-2007 | | | | Office: Ritter Hall 6 | | Email: goldwamh(a)slu.edu | | URL: euler.slu.edu/~goldwasser | | Phone: (314) 977-7039 | | Fax: (314) 977-1452 | +-----------------------------------------------+

[ANN] Scope_Plot, another plot library for real time signals.
by Stef Mientki 04 Nov '07

04 Nov '07

hello, I justed finished, another plot library, called Scope_Plot, based on wxPython. Scope_Plot is special meant for displaying real time signals, and therefor has some new functionalities: - signal selection - each signal has it's own scale, - moving erase block - measurement cursor ans should be a lot faster than MatPlot, Plot and FloatCanvas, at least for real time signals (because it only draws the changes). An animated demo can be seen here (2 MB, 2:10): http://stef.mientki.googlepages.com/jalspy_scope.html A description of the library, as used in an application, can be found here: http://oase.uci.kun.nl/~mientki/data_www/pic/jalspy/jalspy_scope.html And finally the file (and a few necessary libs) can be found here: http://oase.uci.kun.nl/~mientki/download/Scope_Plot.zip The library has a main section which contains a simple demo, the animated demo and the application description shows a more complex signal organization. cheers, Stef Mientki

Roundup Issue Tracker release 1.4.0
by Richard Jones 04 Nov '07

04 Nov '07

I'm proud to release version 1.4.0 of Roundup. The metakit backend has been removed due to lack of maintenance and presence of good alternatives (in particular sqlite built into Python 2.5) New Features in 1.4.0: - Roundup has a new xmlrpc frontend that gives access to a tracker using XMLRPC. - Dates can now be in the year-range 1-9999 - Add simple anti-spam recipe to docs - Allow customisation of regular expressions used in email parsing, thanks Bruno Damour - Italian translation by Marco Ghidinelli - Multilinks take any iterable - config option: specify port and local hostname for SMTP connections - Tracker index templating (i.e. when roundup_server is serving multiple trackers) (sf bug 1058020) - config option: Limit nosy attachments based on size (Philipp Gortan) - roundup_server supports SSL via pyopenssl - templatable 404 not found messages (sf bug 1403287) - Unauthorized email includes a link to the registration page for the tracker - config options: control whether author info/email is included in email sent by roundup - support for receiving OpenPGP MIME messages (signed or encrypted) There's also a ton of bugfixes. If you're upgrading from an older version of Roundup you *must* follow the "Software Upgrade" guidelines given in the maintenance documentation. Roundup requires python 2.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: roundup-demo Release info and download page: http://cheeseshop.python.org/pypi/roundup Source and documentation is available at the website: http://roundup.sourceforge.net/ Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.3+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and five database back-ends (anydbm, sqlite, metakit, mysql and postgresql).
