Experiments with PyPy and libgccjit
by David Malcolm Dec. 16, 2014

Dec. 16, 2014

I'm the maintainer of a new feature for the (not-yet-released) GCC 5: libgccjit: a way to build gcc as a shared library, suitable for generating code in-process. See: https://gcc.gnu.org/wiki/JIT I've been experimenting with embedding it within PyPy - my thought was that gcc has great breadth of hardware support, so maybe PyPy could use libgccjit as a fallback backend for targets which don't yet have their own pypy jit backends. I'm attaching the work I've got so far, in patch form; I … [View More]

Dec. 13, 2014

Dear Ms./Mr. Director / Dear Pypy Team: I'm a e-pal named bitpeach. I'm so interested in your work and admire the Pypy. Therefore, I try to install Pypy and pratice with Pypy during my working and studying. But I got a problem, what is worrying me is that there is few versions of Pypy running on the Windows. So the problem comes as follows: (1)I want to instal Pypy but do not confuse the the 3rd packages or libraries with Python2.7 already in my operate system Windows 7/8 (… [View More]

Unify lib_pypy by vendoring six
by VanL Dec. 6, 2014

Dec. 6, 2014

Hi all, I’ve been doing some experiments with pypy and I would interested in making parts of the codebase more 3x compatible. As a first step, I notice that there are slight differences between the lib_pypy shipped in the 2.7 and 3.2 releases. How would people feel about reducing the duplication by consolidating the lib_pypy implementations? The strategy would be: - vendor six.py within lib_pypy - unify implementation as much as possible, using either compatible syntax or six helpers - if … [View More]

Looking for Python/Twisted developer to work on Open-source
by Tobias Oberstein Dec. 5, 2014

Dec. 5, 2014

Hi, we're looking for an experienced, dedicated Python / Twisted developer to work on http://crossbar.io/ helping us move faster. The code base is around 40k LOC right now, all open-source here https://github.com/crossbario/crossbar https://github.com/tavendo/AutobahnPython This stuff is all new, probably non-trivial, but I'd say technically exciting. Means: a "challenge" should be something that wakes you up;) We have big plans, and we're starting to see strong uptake - both community … [View More]

GSoC 2015: cpyext project?
by Toby St Clere Smithe Dec. 3, 2014

Dec. 3, 2014

Hi all, I've posted a couple of times on here before: I maintain a Python extension for GPGPU linear algebra[1], but it uses boost.python. I do most of my scientific computing in Python, but often am forced to use CPython where I would prefer to use PyPy, largely because of the availability of extensions. I'm looking for an interesting Google Summer of Code project for next year, and would like to continue working on things that help make high-performance computing in Python straight-forward. … [View More]
