by Aahz July 10, 2009

July 10, 2009

NOTE: time change AND location change The July BayPIGgies meeting will be held at OSCON in the San Jose Convention Center as one of the BoF (Birds of a Feather) sessions from 8pm to 9:30pm Thursday July 23. Everyone is welcome: you do NOT need to be an OSCON member to attend a BoF. Wesley Chun will have a newbie-oriented "What is Python?" BoF from 7-8pm in the same room as BayPIGgies (we don't know which room yet). The July meeting is supposed to have a Django focus, but the program hasn't been settled yet, either. For more information, see http://baypiggies.net/ Discussion of details will take place on the BayPIGgies list: http://mail.python.org/mailman/listinfo/baypiggies -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "as long as we like the same operating system, things are cool." --piranha

Pydev 1.4.7 Released
by Fabio Zadrozny July 8, 2009

July 8, 2009

Hi All, Pydev and Pydev Extensions 1.4.7 have been released Details on Pydev Extensions: http://www.fabioz.com/pydev Details on Pydev: http://pydev.sf.net Details on its development: http://pydev.blogspot.com Release Highlights in Pydev Extensions: ----------------------------------------------------------------- * The interactive console can be used on the remote debugger * Remote debugger properly redirects contents from the server on multiple runs. * Providing context-independent completions when other completions are not available (until now, it only gave those completions for method parameters) * The number of chars required to show the context-insensitive completion can now be customized. * Fixed problem with Eclipse 3.5: "Invalid Thread Access" when trying to rename a class Release Highlights in Pydev: ---------------------------------------------- * Iron Python support * Fixed issue when configuring interpreter on Eclipse 3.3 and 3.2 (was using API only available in 3.4) * Google App Engine o Popup menus for google app engine are now working with eclipse 3.2 o Fixed issues when google app engine project has spaces in path * Launching o Ctrl+F9 can be used to run as unit-test and select which tests will be run o F9 will now run the current editor based on the project type o Changed run icons o Run configurations can be created for the project o Run as unit-test can have --filter and --tests as a parameter set in the run configuration * Shift left can now shift even when there are less chars than the required indent string * Top-level modules on .egg files are now properly recognized * Auto-config fixed * Fixed problem when .pydevproject was not a parseable xml file (the pydev package explorer wouldn't work because of that) * When a new interpreter is created, it's properly selected in the tree * Code-completion better heuristic when analyzing function return that's called on self. * Code-completion in the interactive console now handles import sections correctly * Code formatter: Spaces after square and curly braces are no longer changed when an unary operator is found afterwards * Fixed problem when recognizing encodings (regexp was not correct) What is PyDev? --------------------------- PyDev is a plugin that enables users to use Eclipse for Python, Jython and Iron Python development -- making Eclipse a first class Python IDE -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, refactor, debug and many others. Cheers, -- Fabio Zadrozny ------------------------------------------------------ Software Developer Aptana http://aptana.com/python Pydev Extensions http://www.fabioz.com/pydev Pydev - Python Development Environment for Eclipse http://pydev.sf.net http://pydev.blogspot.com

ANN: KeepNote 0.5.3 - Note taking and organization
by rasmus July 8, 2009

July 8, 2009

KeepNote is a simple cross-platform note taking program implemented in Python. I have been using it for my research and class notes, but it should be applicable to many note taking situations. KeepNote is ideal for storing your class notes, TODO lists, research notes, journal entries, paper outlines, etc in a simple notebook hierarchy with rich-text formatting, images, and more. Using full-text search, you can retrieve any note for later reference. KeepNote is designed to be cross-platform (runs on Windows, Linux, and MacOS X, implemented in Python and PyGTK) and stores your notes in simple and easy to manipulate file formats (HTML and XML). Archiving and transferring your notes is as easy as zipping or copying a folder. KeepNote is licensed under GPL. KeepNote 0.5.3 has the following features: * Rich-text formatting * Bullet point lists * Colored font * Inline images * hyperlinks * Hierarchical organization for notes * File attachments * Full-text search * Integrated screenshot * Extension framework * Spell checking (via gtkspell) * Auto-saving * Built-in backup and restore (archive to zip files) * Cross-platform (Linux, Windows, MacOS X) Web site and download: http://rasm.ods.org/keepnote Documentation: http://rasm.ods.org/keepnote/manual.shtml Matt Rasmussen

ANN: SUMMON 1.8.8 Released: 2D Visualization prototyping and scripting
by rasmus July 7, 2009

July 7, 2009

SUMMON 1.8.8 SUMMON is a python extension module that provides rapid prototyping of 2D visualizations. By heavily relying on the python scripting language, SUMMON allows the user to rapidly prototype a custom visualization for their data, without the overhead of a designing a graphical user interface or recompiling native code. By simplifying the task of designing a visualization, users can spend more time on understanding their data. SUMMON is designed to be a fast interface for developing interactive scene graphs for OpenGL. Although python libraries already exist for accessing OpenGL, python is relatively slow for real-time interaction with large visualizations (trees with 100,000 leaves, sparse matrices with a million non-zeros, etc.). Therefore, with SUMMON all real-time interaction is handled with compiled native C++ code (via extension module). Python is only executed in the construction and occasional interaction with the visualization. This arrangement provides the best of both worlds. SUMMON 1.8.8 comes with the following features: * a demo large sparse matrix visualizer (ideal for visualizing clusterings) * a demo tree visualizer * Python C++ extension module * Fast OpenGL graphics * Drawing arbitrary points, lines, polygons, text with python scripting * Binding inputs (keyboard, mouse, hotspots) to any python function * Separate threads for python and graphics (allows use of python prompt and responsive graphics at the same time) * Transparently handles graphics event loop, scrolling, zooming, text layout (auto-clipping, scaling, alignment), and click detection; allowing you to focus on viewing your data * SVG output (also GIF/PNG/JPG/etc via ImageMagick) * Cross-platform (Linux, Windows, OS/X) * And lots of examples for how to prototype your own custom 2D visualizations Web site and download: http://people.csail.mit.edu/rasmus/summon/ Videos: http://people.csail.mit.edu/rasmus/summon/index.shtml#videos

ANN: GMPY 1.10 alpha with support for Python 3
by casevh July 6, 2009

July 6, 2009

An alpha release of GMPY that supports Python 2 and 3 is available. GMPY is a wrapper for the GMP multiple-precision arithmetic library. The MPIR multiple-precision arithmetic library is also supported. GMPY is available for download from http://code.google.com/p/gmpy/ Support for Python 3 required many changes to the logic used to convert between different numerical types. The result type of some combinations has changed. For example, 'mpz' + 'float' now returns an 'mpf' instead of a 'float'. See the file "changes.txt" for more information. In addition to support for Python 3, there are several other changes and bug fixes: - Bug fixes in mpz.binary() and mpq.binary(). - Unicode strings are accepted as input on Python 2. (Known bug: works for mpz, fails for mpq and mpf) - The overhead for calling GMPY routines has been reduced. If one operand in a small integer, it is not converted to mpz. - 'mpf' and 'mpq' now support % and divmod. Comments on provided binaries The 32-bit Windows installers were compiled using MPIR 1.2.1 and will automatically recognize the CPU type and use code optimized for that CPU. Please test with your applications and report any issues found! casevh
