Re: [Python-Dev] "CPython loves your Pull Requests" talk by Stéphane Wirtel
Hi Mariatta, Thank you, I was really happy to see you at my talk, usually this kind of talk is boring ;-) just kidding, but usually I prefer a technical talk.

Re: [Python-Dev] "CPython loves your Pull Requests" talk by Stéphane Wirtel
Hi, Thank you for this post to python-dev. About my talk, it was a real pleasure to give it at PyCon Canada, and I hope I could propose it to PyCon US for a larger public. But the goal behind this talk was to show that we have a good community, firstly by the external contributors and by the core-dev. For the statistics, I used the REST API v3 of GitHub and matplotlib. For the future, I would like to update them via a service running on my own server and maybe submit it to the Python Software Foundation, because I think it's a good indicator for the future contributors of the project. But seriously, I was surprised by the number of Pull Requests and by the number of contributors from Feb 2017 to Oct 2017. Here is my graph for October and November 2017. I will share my scripts on Github and if you want to help me with some good ideas, you are welcome.

Re: [Python-Dev] Micro-optimizations by adding special-case bytecodes?
there is the Peephole for that, it's a small optimizer in the compiler. On 05/24/2017 08:07 PM, Ben Hoyt wrote: Hi folks, I was looking at some `dis` output today, and I was wondering if anyone has investigated optimizing Python (slightly) by adding special-case bytecodes for common expressions or statements involving constants? For example, I (and, based on a quick grep of the stdlib, many others) write "x is None" and "x is not None" very often. Or "return True" or "return None" or "return 1" and things like that. These all expand into two bytecodes, which seems pretty non-optimal (LOAD_CONST + COMPARE_OP or LOAD_CONST + RETURN_VALUE). It seems we could get an easy speedup for these common cases by adding a peephole optimization and some new opcodes (maybe COMPARE_IS_SMALL_CONST and RETURN_SMALL_CONST for these cases). I'm not proposing to do this yet, as I'd need to benchmark to see how much of a gain (if any) it would amount to, but I'm just wondering if there's any previous work on this kind of thing. Or, if not, any other thoughts before I try it?

Re: [Python-Dev] GitHub migration scheduled for Friday
Nice, good news. On 02/07, Brett Cannon wrote: To let the non-core devs know, the GitHub migration will be happening this Friday. For those of you who use the current GitHub mirror to create patches, do be aware that the hashes will most likely be changing so don't expect your checkout to work past Thursday (you can always generate a patch and apply it to a fresh checkout). Otherwise https://cpython-devguide.readthedocs.io/en/github/ is what the devguide will become on Friday if you want to read now instead of waiting for the official switch-over (although for non-core devs the migration basically means you can use GitHub to submit changes instead of uploading patches). ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/stephane%40wirtel.be -- Stéphane Wirtel - http://wirtel.be - @matrixise ___ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
