PyCon early-bird deadline: MONDAY Jan. 17
by Catherine Devlin 13 Jan '11

13 Jan '11

The early-bird registration deadline is coming up fast: it's this Monday, Jan. 17! (AUDIENCE GASPS) Fortunately, everything you need is right here: PyCon 2011, March 9-17: http://us.pycon.org Register: https://www.cteusa.com/pycon4/ Tutorial list: http://us.pycon.org/2011/schedule/lists/tutorials/ Talk list: http://us.pycon.org/2011/schedule/lists/talks/ Hotel reservation: https://www.cteusa.com/pycon4/ Also, keep in mind that, for the first time ever, we've had to place a cap of 1500 on PyCon registration. Delaying too long won't just cause you to miss the early-bird discount, it might make you miss PyCon altogether. While there might be a certain historical thrill in being able to say, "Yes, I was one of the people turned away from the world's first sold-out PyCon"... no, don't do that. Please forward this notice in Python-related groups and mailing lists you belong to. How will you live with yourself if a friend misses PyCon because you didn't tell them? See you in Atlanta! -- - Catherine http://catherinedevlin.blogspot.com

ANN: oejskit 0.9.0 JavaScript in-browser testing, now with py.test 2.0 support
by Samuele Pedroni 11 Jan '11

11 Jan '11

Hi, I'm happy to announce a new release of OE jskit 0.9.0, just pushed to PyPI. Main highlights: - *py.test 2.0 is now supported!* py.test 1.x still works as well - reusing one page (tab/window) for all tests using the same setup in a session is now the default, this is enforced when using py.test 2.0 which collects all tests first - to make the one test page more functional, jskit displays during the test run a list of links on the upper right corner of the pages to easily jump to specific outcome section for a JavaScript test files or python module with JavaScript tests. About OE jskit: jskit contains infrastructure and in particular a py.test plugin to enable running unit tests for JavaScript code inside browsers. It contains also glue code to run JavaScript tests from unittest.py based test suites. The approach also enables to write integration tests such that the JavaScript code is tested against server-side Python code mocked as necessary. Any server-side framework that can already be exposed through WSGI can play. The plugin works with py.test 2.0 or late py.test 1.x. More information and downloading at: http://pypi.python.org/pypi/oejskit jskit was initially developed by Open End AB and is released under the MIT license. Samuele Pedroni

[ANN] cdecimal-2.2 released
by Stefan Krah 10 Jan '11

10 Jan '11

Hi, I'm pleased to announce the release of cdecimal-2.2. cdecimal is a fast drop-in replacement for the decimal module in Python's standard library. Blurb ===== cdecimal is a complete implementation of IBM's General Decimal Arithmetic Specification. With the appropriate context parameters, cdecimal will also conform to the IEEE 754-2008 Standard for Floating-Point Arithmetic. Typical performance gains over decimal.py are between 30x for I/O heavy benchmarks and 80x for numerical programs. In a PostgreSQL database benchmark, the speedup is 12x. +---------+-------------+--------------+-------------+ | | decimal | cdecimal | speedup | +=========+=============+==============+=============+ | pi | 42.75s | 0.58s | 74x | +---------+-------------+--------------+-------------+ | telco | 172.19s | 5.68s | 30x | +---------+-------------+--------------+-------------+ | psycopg | 3.57s | 0.29s | 12x | +---------+-------------+--------------+-------------+ In the pi benchmark, cdecimal often performs better than Java's BigDecimal running on Java HotSpot(TM) 64-Bit Server VM. Both cdecimal and the underlying library - libmpdec - have very large test suites. libmpdec has 100% code coverage, cdecimal 85%. The test suites have been running continuously for over a year without any major issues. Install ======= Since cdecimal is now listed on PyPI, it can be installed using pip: pip install cdecimal Windows installers are available at: http://www.bytereef.org/mpdecimal/download.html Links ===== http://www.bytereef.org/mpdecimal/index.html http://www.bytereef.org/mpdecimal/changelog.html http://www.bytereef.org/mpdecimal/download.html Checksums of the released packages ================================== sha256sum --------- 3d92429fab74ddb17d12feec9cd949cd8a0be4bc0ba9afc5ed9b3af884e5d406 mpdecimal-2.2.tar.gz e8f02731d4089d7c2b79513d01493c36ef41574423ea3e49b245b86640212bdc mpdecimal-2.2.zip 515625c5c5830b109c57af93d49ae2c57ec3f230d46a3e0583840ff73d7963be cdecimal-2.2.tar.gz sha1sum ------- 24695b2c9254e1b870eb663e3d966eb4f0abd5ab cdecimal-2.2.win32-py2.6.msi e74cb7e722f30265b408b322d2c50d9a18f78587 cdecimal-2.2.win32-py2.7.msi 7c39243b2fc8b1923ad6a6066536982844a7617f cdecimal-2.2.win32-py3.1.msi 5711fd69a8e1e2e7be0ad0e6b93ecc10aa584c68 cdecimal-2.2.win-amd64-py2.6.msi b1cd7b6a373c212bf2f6aa288cd767171bfefd41 cdecimal-2.2.win-amd64-py2.7.msi f08a803a1a42a2d8507da1dc49f3bf7eed37c332 cdecimal-2.2.win-amd64-py3.1.msi cb29fa8f67befaf2d1a05f4675f840d7cd35cf6c cdecimal-2.2-no-thread.win32-py2.6.msi 012a44488f2ce2912f903ae9faf995efc7c9324b cdecimal-2.2-no-thread.win32-py2.7.msi 1c08c73643fc45d7b0feb62c33bebd76537f9d02 cdecimal-2.2-no-thread.win32-py3.1.msi b6dbd92e86ced38506ea1a6ab46f2e41f1444eae cdecimal-2.2-no-thread.win-amd64-py2.6.msi b239b41e6958d9e71e91b122183dc0eaefa00fef cdecimal-2.2-no-thread.win-amd64-py2.7.msi 413724ff20ede7b648f57dd9a78a12e72e064583 cdecimal-2.2-no-thread.win-amd64-py3.1.msi Stefan Krah

PyCon 2011 - Full talk and tutorial list now available, registration open!
by Jesse Noller 08 Jan '11

08 Jan '11

I'm very pleased to announce, on behalf of the PyCon 2011 Program committee, and entire PyCon 2011 volunteer staff, that the full list of PyCon 2011 talks is now public, and available! This was an especially hard year for the PyCon program committee: we had over 200 proposals for only 95 total slots, so we ended up having to reject a lot of excellent proposals. We've spent the better part of the last few months in reviews, meetings and debates selecting which talks would be in the final PyCon program. It was not and easy task - all of the proposal authors really came through in their proposals - the number of high quality proposals we had to chose from was simply staggering. That said - the program committee completed it's work yesterday morning. Acceptance and rejection letters have been sent, and you can now view the full program on the site: http://us.pycon.org/2011/schedule/lists/talks/ This obviously complements the list of tutorials also available: http://us.pycon.org/2011/schedule/lists/tutorials/ Personally, this is my second year acting as the Program Committee chair (and hence, my last) - and between the talk list, and the list of tutorials, our current keynote speaker (http://us.pycon.org/2011/home/keynotes/) and the emerging line of up poster sessions - I'm extremely proud to have been part of the process, and extremely excited about the upcoming conference. It is going to be amazing One behalf of the entire PyCon 2011 staff, I want to again thank every single talk author for their submission(s), and I look forward to seeing all of you, and them at the conference. PyCon is an amazing conference only because of the quality talks, tutorials and community we have. I'm confident this one will knock it out of the park. As a reminder: Early Bird registration (http://us.pycon.org/2011/tickets/) closes January 17th - and we have an attendance cap of 1500 total attendees (speakers are counted against this number, and guaranteed a slot) so be sure to register today!
