Re: Some Python Benchmarks

Very interesting, the second example, euler135.py I have no idea why it is slower in pypy.

GSoC Project idea

Hi everyone, my name is Tamreen Khan (Scriptor on IRC) and I'm
interested in working on PyPy for Google's Summer of Code. I have
experience in Python, basic knowledge of assembly, and I'm interested
in language implementation. Otherwise, I'll have to learn much of the
rest myself. I'm currently working on an abstract register allocator
(doesn't deal with actual CPU registers) that fijal asked me to write
before I apply. However, I would like to start getting figuring out
what I would do for my actual summer project.

I understand that the JIT is a priority spot for development right
now. Also, on the ideas page, I saw that integrating Stackless better
is a possible project and I'd like to work on that, although I think
someone on IRC was already doing that.Besides what's on the ideas
page, does anyone have any suggestions for areas in PyPy that I could
pick to create my own idea if needed?

Thanks,
Tamreen Khan

Student application deadline on friday for SoC

Hello.

All students should submit their application ASAP. There is no point
in waiting for friday IMO, especially that you can change it
afterwards.

Cheers,
fijal

Just FYI so there aren't any unpleasant surprises for someone, my 
understanding is that you *can't* edit it afterwards. A tidbit from the 
resident bot in the #gsoc channel:

<socinfo> "edit" is You can submit your application early and edit it up 
until the deadline (April 9). Once the deadline passes, you cannot edit 
it. Instead, leave comments.

But in any case, students should definitely submit their applications 
right away.

Re: Python Ireland Conference

Hi,

Apologies for the late response, I picked a good time to go on holidays :)

We don't have a fixed deadline defined at the moment, so I'd say you'd
get away with the end of June before making a firm decision.

Hope you can make it!

cheers,
  Michael

Re: Student application deadline on friday for SoC

Hi, after thinking this through I've decided that I won't apply for
Summer of Code, mainly because I don't think I'll be able to make the
full-time commitment needed. I would still like to continue to work on
the project, however.

Re: Student application deadline on friday for SoC

I haven't submitted yet, but here's what should be very close to the finished proposal: http://codespeak.net/~dan/gsoc/micronumpy.html Any and all comments and suggestions are welcome.  Please ignore the ugly feature list though... I don't think it will be in the final revision.

vfs.py - sandboxing with option to write

Hi,

 

I have been tracing: vfs.py, pypy_interact.py  and sandlib.py.

 

Just to make sure that I got it right.

 

* The object RealFile in vfs.py is first used then we know that here is a  RealFile on the real system that is the --tmp=directory, the method is also use on python files I can see from my trace?

 

* The join method in RealDir is the key, because it maps (join) the virtual filename to a real filename og real directory

 

So if I want to expand the vfs.py I need to modify RealDir to allow to return RealFile for files that are new, that is that they are not part of names.

 

On files that do exist and I want to write to then, I do not have a clue. As I can see I get the error even then I open the file using open( "myFile", "w"). And

because of that I am not sure about my previous statement " So if I want to expand the vfs.py I need to modify RealDir to allow to return RealFile for files that are new, that is that they are not part of names."

 

Regards,


Søren Laursen

mozilla speed website

Hi all,

Just wanted to point out the website Mozilla is using to track their 
JIT's progress (it's quite a bit less polished then what we have, but 
still):

http://arewefastyet.com/

As a reference "jaeger" refers to the new per-method JIT compiler 
Mozilla is writing, that is supposed to run before tracing kicks in. 
Right now it doesn't seem to help much, even over interpretation.

Cheers,

Carl Friedrich
