funding/popularity?
by Dima Tisnek Dec. 21, 2010

Dec. 21, 2010

First of all, congratulation on getting Eurostars Would be nice if companies that use Python extensively chipped in [more]. By [out of] my [@%%] calculations, each percent of perfromance improvement that pypy achieves potentially saves google many millions a year in data centre costs. What are other companies use/love python and how much? Popularity, I for one would like python to be used much more widely; it is of course a double-edges sword, on one hand more users and developers means more … [View More]

playing with fast-forward
by Gary Robinson Dec. 20, 2010

Dec. 20, 2010

I'm experimenting with the fast-forward branch. I'm actually not sure about the proper way to get it. (I have the main branch working fine.) I downloaded a nojit version from http://buildbot.pypy.org/nightly/branch/fast-forward/ since I didn't see any jit versions listed there. I was happy to see that the method I care most about, multiprocessing.Pool.imap_unordered, seemed to work. But I want to test it with the jit. The page (https://bitbucket.org/pypy/pypy/src/021b219e0aef) appears to be … [View More]

speed.pypy.org and mercurial
by Antonio Cuni Dec. 18, 2010

Dec. 18, 2010

Hi Miquel, hi all, as you probably have noticed, we have recently migrated the main repo to mercurial. Now speed.pypy.org receives a revision number in the form "40046:2088ce763fc2", but of course it can no longer fetches the commit logs from the svn server. Would it be possible to fetch the commits from the bitbucket repo, please? ciao, Anto

Can't run PyPy due to missing libbz2.so.1.0
by Gary Robinson Dec. 17, 2010

Dec. 17, 2010

When I try to start PyPy, I get: bin/pypy: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory This is on a SuSE Linux Enterprise Server 10.3 SP2. This system does have: /lib/libbz2.so.1.0.0 As a quick experiment, I tried temporarily renaming it to /lib/libbz2.so.1.0 but that didn't change the result. I also tried installing the bzip2 package from the rpm, but it said it was already installed. Can anyone suggest a solution? … [View More]

Mercurial workflow
by Jacob Hallén Dec. 16, 2010

Dec. 16, 2010

Hi folks, now that the switch to Mercurial has happened, people are discovering that their Subversion workflow habits don't quite work. This is because Mercurial has a distributed philosophy, inlike svn which has the concept of the holy central server where all operations take place. In Mercurial, you do all the important operations in your local repository. If you have a central node (which is not strictly necessary), you just push ready made change sets to it. Any conflict resolving … [View More]
