[ANN] Pyspread 0.0.14b released
by Martin Manns 13 Mar '10

13 Mar '10

Pyspread 0.0.14b released ========================= I am pleased to announce the new release 0.0.14b of pyspread. About: ------ Pyspread is a cross-platform Python spreadsheet application. It is based on and written in the programming language Python. Instead of spreadsheet formulas, Python expressions are entered into the spreadsheet cells. Each expression returns a Python object that can be accessed from other cells. These objects can represent anything including lists or matrices. Pyspread runs on Linux and *nix platforms with GTK support as well as on Windows (XP and Vista tested). On Mac OS X, some icons are too small but the application basically works. Homepage -------- http://pyspread.sourceforge.net New features ------------ * Cell border can be changed independently. * Cell access allows negative indices when not slicing. Enjoy Martin

PyPy 1.2, JIT included
by Armin Rigo 12 Mar '10

12 Mar '10

================================== PyPy 1.2: Just-in-Time Compilation ================================== PyPy 1.2 has been released. The highlight of this release is to be the first that ships with a Just-in-Time compiler that is known to be faster than CPython (and unladen swallow) on some real-world applications (or the best benchmarks we could get for them). The main theme for the 1.2 release is speed. Main site: http://pypy.org/ The JIT is stable and we don't observe crashes. Nevertheless we would recommend you to treat it as beta software and as a way to try out the JIT to see how it works for you. Highlights of This Release ========================== * The JIT compiler. * Various interpreter optimizations that improve performance as well as help save memory. * Introducing a new PyPy website at http://pypy.org/ , made by tav and improved by the PyPy team. * Introducing http://speed.pypy.org/ , a new service that monitors our performance nightly, made by Miquel Torres. * There will be ubuntu packages on "PyPy's PPA" made by Bartosz Skowron; however various troubles prevented us from having them as of now. Known JIT problems (or why you should consider this beta software): * The only supported platform is 32bit x86 for now, we're looking for help with other platforms. * It is still memory-hungry. There is no limit on the amount of RAM that the assembler can consume; it is thus possible (although unlikely) that the assembler ends up using unreasonable amounts of memory. If you want to try PyPy, go to the "download page" on our excellent new site at http://pypy.org/download.html and find the binary for your platform. If the binary does not work (e.g. on Linux, because of different versions of external .so dependencies), or if your platform is not supported, you can try building from the source. What is PyPy? ============= Technically, PyPy is both a Python interpreter implementation and an advanced compiler, or more precisely a framework for implementing dynamic languages and generating virtual machines for them. The focus of this release is the introduction of a new transformation, the JIT Compiler Generator, and its application to the Python interpreter. Socially, PyPy is a collaborative effort of many individuals working together in a distributed and sprint-driven way since 2003. PyPy would not have gotten as far as it has without the coding, feedback and general support from numerous people. The PyPy release team, Armin Rigo, Maciej Fijalkowski and Amaury Forgeot d'Arc Together with Antonio Cuni, Carl Friedrich Bolz, Holger Krekel and Samuele Pedroni and many others: http://codespeak.net/pypy/dist/pypy/doc/contributor.html

RSON v 0.02 available
by Patrick Maupin 12 Mar '10

12 Mar '10

RSON (Readable Serial Object Notation) is a superset of JSON that is suitable for files that humans have to edit and diff. The current release is decoder-only, but the decoder will read files encoded by JSON encoders such as json or simplejson. The current release consists of a single Python module and a short manual. The manual admittedly needs some work, but has a few syntax examples. http://code.google.com/p/rson/

Command-Line Code Dojo this month, Jabber/XMPP next month in Toronto
by Mike C. Fletcher 10 Mar '10

10 Mar '10

We'll be having our regular Greater Toronto Area Python User's Group (PyGTA) meeting this month and next. * Command-Line Apps (Code Dojo) -- Tues, March 16th, 7pm o Want to create utilities that do "one thing well" in the Unix philosophy? o We'll be exploring methods for how to accomplish this using collaborative on-screen coding. All experience levels welcome. * Jabber/XMPP in Python -- Tues, April 20th, 7pm o XMPP is chat. It's the underlying protocol for open peer-to-peer communication systems, but what becomes possible when the peers are servers? How can you make your server a chatty teen? Myles Braithwaite uses XMPP a lot. He ships documents and data-sets across it that look nothing like the chatter of teenagers. He'll explain how he does this, why he does this, and how you can do it too. Regular time (Third Tuesday of the Month) and place (Linux Caffe). More details on the web site: http://www.pygta.org Enjoy, Mike -- ________________________________________________ Mike C.

Hi, The 0.9.7 release of BetterBatch is now available. BetterBatch is designed as a middle ground between batch files and more powerful languages (Python, shell scripting, etc). The project is hosted on code.google.com: http://code.google.com/p/betterbatch/ Download from http://code.google.com/p/betterbatch/downloads/list Or discuss at http://groups.google.com/group/betterbatch-discuss/topics Here is the list of changes from the last release: 0.9.7 Functions, negative conditions, Setup/Installer and test fixes ------------------------------------------------------------------ 07-March-2011 * Add preliminary support for Functions, give it a try and let me know. * Add support for negative conditions for IfSteps. (e.g. if not exists, if not defined, etc) * Add a supported qualifier to VariableDefinition Steps to allow delayed resolution for Variable references. * Allow defined to use <var_name> as well as var_name. (usability) * Due to a case issues (tools/Tools) the betterbatch\tools folder was left out of the distribution. There was also a bug that meant when this folder wasn't found BetterBatch would not run. (fixed in 0.9.6b) * Fix the old tests (change what could be changed and comment out the rest) * Change setup.py so that Setuptools will be used if it is available - otherwise docutils. (fixed in 0.9.6b) * Add a -t/--timed option to print how long the script took to execute. * Fix manifest.in to include/exclude more files. (fixed in 0.9.6b) * Cleaned up the the output messages of PathExists(), PathNotExists() and VerifyFileCount() * Ensured that the Testing phase is more silent (some messages that should only be displayed during execution phase were being logged) * Some other small fixes. * Many thanks to Yuhui for pointing out many of these issues on the mail list. If you want to check at the home page. If you find an bug or have a suggestions then please log an issue at http://code.google.com/p/betterbatch/issues/entry Thanks Mark <P><A HREF="http://code.google.com/p/betterbatch/">BetterBatch 0.9.7</A> Powerful, safe and simple batch language.
