Forwarding it again to pypy-dev. Sorry missed the first time. Regards, Vishal ---------- Forwarded message ---------- From: Vishal <vsapre80(a)gmail.com> Date: Sun, Oct 16, 2011 at 10:51 PM Subject: Re: [pypy-dev] Anyone interested in a MIPS port... To: Armin Rigo <arigo(a)tunes.org> Thanks Armin. Appreicate your email a lot. I had sort of lost track of this message. My final target is actually a 32 bit microcontroller from Microchip, the very famous PIC32 family. RAM is a big issue there...atleast I dont know what is the exact way of expanding ram on that architecture. MIPS though is available from many other companies, and has been the embedded workhorse of the last decade. Will be happy to help to someone who would take the lead in this effort. The python-on-a-chip project is more what microcontroller guys should look at.

Anyone interested in a MIPS port...
by Vishal 16 Oct '11

16 Oct '11

Hello, I would like to collect volunteers for a MIPS port of PyPy JIT. MIPS is used across the embedded scene universally and a PyPy support for MIPS would be wonderful. So I have 2 questions (may seem like very nuby like...pardon me for that): a) Does it make sense to have a MIPS port of the PyPy JIT. b) How much hardware dependent is a JIT port? Thanks and best regards, Vishal Sapre

How to organize the py3k branch (was: [pypy-commit] pypy py3k: Remove print statement)

I thought that the idea was to have support for python 2 and 3 from the same codebase, while from your commits it seems that your are actually destryoing support for python 2. I think that there are several possible ways to organize the source code, each one with pros and cons. Maybe we should organize an IRC meeting with the interested people to decide which direction to follow? I.e., a list of possibilities (everyone feels free to add more): - have a branch where we have *only* python3, and rely on hg merge to get the improvements to the translator (which is what you are doing right now, I think). It's easier to write, but then it might be hard to keep in sync with the default branch - support for py2 and py3 in the same branch, with minimal duplication of code. This would mean that e.g. in ast.py you would have tons of "if py2: enable_print_stmt()", etc. Personally, I think that the codebase would become too cluttered. - support for py2 and py3 in the same branch, with some duplication of code; e.g., we could copy the existing interpreter/ into interpreter/py3k and modify it there. While we are at it, we should try hard to minimize the code duplication, but then it's up to us to decide when it's better to duplicate or when it's better to share the code between the twos. - other? ciao, Anto

I am very happy to finally see an amount-feedback with numbers and bars for py3k on the website ! Thank you so much! Could that also happen for the numpy-funding? As much as I know, 1200 british pounds have allready been pledged, which shall be 1880 USD...

First draft in extradoc. Please add the more details of the topics we want to discuss, and decide whether you want to do the sprinting at my house or at OE. I am fine with either. I don't think there will be any actual construction happening in the house at this time. If I am wrong, I will let you know as soon as I do. Laura

Gothenburg Sprint Dates
by Carl Friedrich Bolz 13 Oct '11

13 Oct '11

Hi all, Laura asked me to post the following, since she has problems with her mail: ---------------------------------------------------------------------- Some of us need to be in Stockholm Oct 24 and 28. Anto needs to be with his family Nov 1. Fscons starts Friday Nov 11 in Göteborg, and we're giving a talk. Thus I propose that we hold a Sprint at my house Wednesday Nov 2nd through Thursday Nov 10. fscons: http://fscons.org/ Nov 11-13 Not sure what day we will be speaking yet. What do the rest of you think of this idea? Laura

And, again as always, I think that sprint funding is the very best use we can make of our money, as a general principle. Laura

Just to clarify: I am fine with all of you eating at my house and cooking together if that is what is required. It is just the 'sleeping at my place' part which is temporarily broken, because I don't have any bathing facilities to offer you (showers and bathtub). The laundry and toilets are fine. It just sounded like a good idea to have a sprint in Gbg at this time because of the fscons and vinnova connection at this time. If people want to sprint someplace else, I am fine with that too. Laura, who cannot even begin to tell you how much she is sorry about this ...

With mercurial it should be very easy to get a diff against the original one whenever we want. ciao, Anto
