IRC server unreachable

Hi,

am I the only one unable to join any freenode IRC servers ? I get
connection refused errors on servers listed on
http://freenode.net/irc_servers.shtml

Or has the IRC network for pypy changed ?

See interpreter/test/test_executioncontext.py, or look at how
module/thread/__init__.py adds an action that is called back every Nth
bytecode instruction.

A bientot,

Duesseldorf sprint report

Hi all!

it is with a familiar level of tiredness that we bring you these lines.
We are again sitting in one of the rooms of the Institut für Informatik,
after 6 days of sprinting. As usual, it has been a busy and productive
(and sometimes strange) sprint.

One of the new developments of the sprint was the work of Leonardo
Santadaga, our "Summer" of PyPy student from Brazil. Leonardo proposed
to write a JavaScript interpreter, had his proposal accepted and now
gets his travel to sprints funded. This work has seen good progress
every day, so that we now have an interpreter that handles simple
snippet of JavaScript code. Leonardo had help from various other people
changing over the course of the sprint such as Maciek, Guido (the
reluctant Master of JavaScript) and Stephan. The parser is currently
stolen from them Narcissus project, and the interpreter does not
translate yet. For less than a weeks work though we think are doing
pretty well (we are trying not to distract ourselves with crazy thoughts
like translating a JS interpreter to JS or wondering how fast it would
be after applying the magic JIT technology). Although Leonardo will be
flying back to Brazil soon he will continue working on it (at least if
he finds sufficient time between caring for his beloved new MacBook).

The other PyPy sprint virgin was Niko Matsakis, a graduate student at
ETH Zürich. To start with he worked with help of Antonio on the
fledgling JVM backend. Antonio and Niko worked on moving code out of the
CLI backend to be shared with other object-oriented backends. They got
as far as supporting nearly everything except constants (which as usual
turns out to be the hardest thing to support). The team was split up
later in the week to work on Other Things. Niko only found out after he

Re: Duesseldorf sprint report

Congratulations to you all. You have been extremely productive and seem to 
have managed to have fun at the same time. Wish I could have been there.

Summer of PyPy Call for Proposals

Last chance to join the Summer of PyPy!
=======================================

Hopefully by now you have heard of the "Summer of PyPy", our program for
funding the expenses of attending a sprint for students.  If not, you've
just read the essence of the idea 

However, the PyPy EU funding period is drawing to an end and there is
now only one sprint left where we can sponsor the travel costs of
interested students within our program. This sprint will probably take
place in Leysin, Switzerland from 8th-14th of January 2007.

So, as explained in more detail at:

    http://codespeak.net/pypy/dist/pypy/doc/summer-of-pypy.html

we would encourage any interested students to submit a proposal in the
next month or so.  If you're stuck for ideas, you can find some at

    http://codespeak.net/pypy/dist/pypy/doc/project-ideas.html

but please do not feel limited in any way by this list!

Cheers,

Carl Friedrich Bolz and the PyPy team

JIT improvements for RISC processors

Hi to everyone,

I am really interested in code machine generation for risc processors.
In order to have an idea of the work that can be done, and to create
a proposal I will ask some questions:

- What is already done? where is it? (paths, file names please)
- What ideas are already defined and need just to be implemented?
- Material that I have to / should read?

I have a rough background on RISC assembler,
the most comes from MIPS and IBM's PowerPC

some material I am aware of is http://tinyurl.com/9dw43

Don't let me escape for the second (last?) time!
:)

interesting paper on a object-oriented language for very constrained embedded systems

http://compilers.cs.ucla.edu/virgil/virgil-oopsla06.pdf 
<http://compilers.cs.ucla.edu/virgil/virgil-oopsla06.pdf>

RPython for different reasons or by different means does similar things 
already (devirtualisation,
separate flexible load time) and could be adapted to implement other 
aspects/optimisations as well,
under the no new allocations assumption.

regards.
