You seem to work faster than me at the moment. I'm still stuck with finishing my thesis. But I'll submit my binascii code before chrismas, I promise ;-) I wouldn't convert … [View More]

Switzerland sprint around Jan 22-29
by Armin Rigo Dec. 10, 2004

Dec. 10, 2004

Hi all! The next sprint will take place in Leysin, in the Swiss pre-alps. The precise dates are not fixed yet, but it will almost certainly be during the week of the 22-29th January. Leysin is a village at an altitude of 1200 to 1400m. It is a skiing station, and also the place where I lived for 20 years. There are 2000 people in summer and 10000 in winter :-) but the sprint will be just before the most crowded periods of February. Of course at least one full day will be dedicated to … [View More]

[patch] bitwise binary operators
by Olivier Dormond Dec. 9, 2004

Dec. 9, 2004

Oops! Armin told me that nonneg means that we know for sure that the value is not negative (i.e. postive or null). In that case the xor behave differently. Hopefully this patch will do it right.

[patch] bitwise binary operators
by Olivier Dormond Dec. 7, 2004

Dec. 7, 2004

Hello, Here is a small patch that add the and_, or_ and xor bitwise operators. It also replaces the add method which is identical to union by a synonym.

unlurking
by Douglas McNeil Dec. 6, 2004

Dec. 6, 2004

Hi, all. Brief intro: Canadian astronomy graduate student, does lots of python programming, thinks pypy is a cool idea and has been lurking for a long time. :) Some of my codes are in C for speed reasons, but they're a lot uglier than the python equivalents would be.. I really wish there were a way to get C speed out of python without going the numarray/pyrex/weave routes, so the translator/annotator stuff interests me for reasons entirely unrelated to pypy itself. Numeric codes tend not to … [View More]

EU funding is official!
by hpk＠trillke.net Dec. 6, 2004

Dec. 6, 2004

Hi pypythonistas, lucky day! The EU signed the contract and the PyPy/EU projects starts, umm, started on 1st of December 2004! This means we have now two years of funding for PyPy to deliver research and implementation results. The funding will go to a number of people (through their respective organizations) who already are involved in the project for a long time. But this doesn't mean that there is not room for new fellow hackers especially with research interests! After our … [View More]

Hi! I have attached a patch for autopath.py. It fixes the __clone function for windows. I don't know whether it still works on unix, but I think it should. Regards, Florian Schulze
