Actually at least some core developers are discussing core terminologies for quite some time now, especially when we have to synchronize and give a talk together (we often do group-talks, i.e. not only one person speaking the whole time). > So how to identify/create a representation of a project for a prospective > explorer?

Note that the main entry page has a cross-referenced directory index. cheers, holger

Refining terminology
by holger krekel 12 Jul '05

12 Jul '05

Hi folks, i have just started to write some documentation about PyPy's bytecode interpreter (only the overview chapter in fact see http://codespeak.net/pypy/index.cgi?doc/interpreter.html ). And i realized that i'd like to push to refine the terminology we are using throughout the PyPy documentation and our presentations. For starters, i think that it does not make sense to fight against the common notion of an "interpreter" refering to the whole thing (our bytecode interpreter + objectspace). If we want to refer to the "pure" thing, we should thus talk of the "bytecode interpreter". Usually refering to our (Python) Interpreter then really means StdObjSpace + the bytecode interpreter. Other wording issues are the various "times", "levels", "phases" and "passes" we are talking about. I think we desparately need pictures to support a clear and consistent terminology and make it more obvious to everyone. This may become even more important when we'll go for a JIT-compiler interweaving levels as well as compile- and runtimes some more. Well, maybe we should just go through the effort of creating a "glossary" containing the basic vocabulary we are using for describing what PyPy does and how it works. And i think we should try to reuse common VM/Compiler terminology, even refering to Wikipedia and other public resources, to make it easier for non-Python/PyPy crowds to understand what we are doing. I guess that some of you may think that it is only real working code that matters (i know some do :-). But i think this is not true. Communicating the concepts is and has always been a major issue of the whole project. Any opinions or feedback (also from people just following the project's progress)? cheers, holger

Please give advice for newbie reading pypy source......

PyPy Developers: I'm really excited about learning PyPy source code really well and possibly helping the project in some capacity. Reading source code inevitably leads to tons of questions. **Any advice on how to progress quickly in PyPy source code understanding?** Any chance there are PyPy people close to San Diego, California?? Any better method than posting questions to this mailing list and slowly getting replies to all my questions? Any help would be greatly appreciated.

amep (~amp(a)user-12lcgki.cable.mindspring.com) has joined channel #pypy <amep> I wanted to say how cool I think pypy is. And how much I'm looking forward to a complete release. I'm writing a program that would really be improved by some extra speed and I'm sure pypy will be able to provide that. (Machine code output and all) amep has left channel #pypy Laura

os.getuid

Hello PyPyers! I was just wondering if anyone had noticed that on windows (and cygwin) os.getuid doesn't actaully exist, and so I am getting lots of failures. I see that great progress is being made anyhow! Is there a status report due out a the end of the sprint so us observers can see what has been done? Cheers, Ben
