progress with numpy and removal of numpy.py
by Matti Picus Oct. 29, 2013

Oct. 29, 2013

I have been working to get numfocus benchmarks written for numpy to run on numpypy and pypy https://github.com/numfocus/python-benchmarks The biggest obstacle is actually the need for matplotlib, which is used internally to produce pretty comparisons between different benchmarks. Luckily, Stefan H. Muller did much of what is needed to use matplotlib (non-interactively) with pypy, I have taken over his work and it now lives in two git repos: https://github.com/mattip/numpy on the pypy-… [View More]

Fwd: LLVM stackmaps
by Armin Rigo Oct. 29, 2013

Oct. 29, 2013

Hi all, hi mjacob, Someone interested in the port to llvm could have a look at this: http://llvm-reviews.chandlerc.com/file/data/qnievreabgj3qqnco3ax/PHID-FILE-… It adds two different things. The first is stackmaps, which could replace shadowstack/asmgcc for regular translation. The second is patchpoints, which together with stackmaps could potentially be used for a llvm JIT backend's guards. A bientôt, Armin.

pypi blog shows strange on planet.python.org

The last "Making coverage.py faster under pypy" blog shows strangely on the Python planet, check it out: http://planet.python.org/ I guess it's not a good idea to include the docutils comments or so. IIRC this didn't happen before. best, holger

Using RPython for a semi-statically-typed language
by Ryan Gonzalez Oct. 27, 2013

Oct. 27, 2013

Hello, I am in need of a little assistance. I am thinking of writing a language in RPython. Now, here is what I want: -Polymorphism(C++) without pointers, i.e., Derived can be implicitly cast to Base I am thinking of picking RPython because of the JIT. However, I am worried about the speed. I know the JIT PyPy generates is fast, but if it's the same speed as PyPy itself, someone would easily pick PyPy or Topaz or the like. My question is: For a somewhat statically-typed language like I am … [View More]

error message with windows
by Trevor Langevin Oct. 27, 2013

Oct. 27, 2013

Hello, I'm learning 3D printing, and to use Skeinforge it was recommended to download your pypy program to use on a windows machine. I get an error message while trying to unzip you program "Please insert the last disk of the multi-disk set?" Where do I find this disk, its not included in the installer package? Trev I could not log on to your bug tracker site, firefox would not let me view the page as its listed as untrusted.

pypy-stm and lock-free data structures
by Andrew Francis Oct. 25, 2013

Oct. 25, 2013

Hi Folks: I have been reading a few papers on lock-free data structures (and reading some posts on Golang Nuts). I was thinking about writing new a version of stackless.py with Go's select. However I would try to use lock free data structures and techniques in the channel implementation. My questions: 1) Would I be using the pypy-stm branch? (because there is no GIL) 2) Would I write some of this in RPython? (I am assuming yes) 3) Do I have access to low-level atomic operations (I don't think … [View More]
