hello python developers, the fourth PyPy coding sprint will take place in Berlin (Germany) from (morning of) 29th of September to (evening of) 4th of October 2003. All Python developers are welcome to join the sprint. See below for participation details. What is PyPy? ------------- PyPy is a remimplementation of Python in the Python language itself. Simplicity and flexibilty are the foremost goals. With PyPy we want it to be easy to extend the language or generate a more minimal language implementation. One key technique to making this feasible is to specialize our abstract/general PyPy-Python implementation into native code (e.g. C-code). Eventually the concepts of PSYCO and Stackless are to be integrated into PyPy. There is, of course, much more to it so feel free to consult some documents especially our Oscon-2003 paper on this page: http://codespeak.net/pypy/index.cgi?doc We know that many areas and issues are still somewhat vague although PyPy can already run many python programs [*]. Fortunately, Python is pretty tolerant about expressing ideas in vague ways. After all, hacking at PyPy aims (and already proved!) to preserve the fun of hacking in Python. History, status and Berlin goals -------------------------------- The project started in Jan/Feb 2003 with an initiative from Christian Tismer, Holger Krekel and Armin Rigo. During the course many more developers joined our sprints and there are now between 5 and 15 people involved in developing PyPy. The three sprints resulted in a fully working interpreter, some development infrastructure and the "standard object space" which is an abstraction for operations on standard (CPython) objects. There is no public release yet, you more or less have to install a subversion-client and checkout the trunk. Here is our 'howtosvn' which contains up-to-date clients for multiple platforms along with some instructions how to get started: http://codespeak.net/pypy/index.cgi?doc/devel/howtosvn.html Main goals for the Berlin sprint are - integration/enhancement of a Python parser and the compiler package - generating native code from our Python interpreter/types implementations - enhancing/correcting/completing what we have (various tasks) How to participate in Berlin (29th of Sept. to 4th of October) -------------------------------------------------------------- If you are interested to participate please subscribe at our sprint organization list http://codespeak.net/mailman/pypy-sprint and please list yourself at http://codespeak.net/moin/pypy/moin.cgi/SprintAttendants so that we can organize accomodation and arrange details. Costs should be pretty low (except from travelling costs, of course). Currently nine people are scheduled to come. Btw, the sprint starts early on the 29th of september so it's best to arrive on sunday, 28th. Also we probably want to have one day off during the sprint week to do some sight (or cafe+pub) seeing. Actually it's much better to participate the whole week to better get into it. cheers, holger [*] and currently only 20-40 thousand times slower than CPython! which clearly shows that we are successfully follow the "premature optimization is the root of all evil" maxime.
