Subversion questions

It looks like I'm going to invest in a server to host all my web activities. I'll have root access and can install whatever I want. So I'll be installing subversion. What particular setup has worked well for the PyPy folks? I'll probably use Debian for the OS. Also, Laura, are you using Subversion from within Emacs? If so, what did you do to set that up? I *love* accessing cvs from Emacs, so I'd like to be able to do the same with Subversion. Since I'll have unlimited domain capabilities, I can host the entire project, if you want. I'll be installing Mailman, so I can set up some mailing lists as well. If we can decide on a name (unless everyone is happy with restweb), I can register the domain name as well. The following are available: restweb.net rest-web.com rest-web.net rest-web.org If someone else wants to host this (Holger, Stepen) that's fine. Just thought I'd offer. -- Patrick K.

Here is what would be my ideal system: * text files written using reST conventions * text files stored in cvs or svn * style sheet to work with reST that ends up looking like Tim's design * the result is static html pages that are search engine friendly Here is how people would contribute website content: * read tutorial about reST and updating content * ask for privileges at the cvs or svn repository * check out the files from cvs or svn * make changes in preferred text editor, or * check out the templates and create a new document * run unit tests which make sure the html gets created properly * make sure the html results look good with the style sheets * check the changes into the cvs or svn repository * cvs or svn changes get emailed to anyone who wants to monitor them * someone can reverse the changes, just like code in cvs or svn * the website gets rebuilt from the cvs or svn reposity each day If the content is in reST, we can also produce XML, PDFs, latex, OpenOffice, etc. Thoughts? - -- Patrick K.

I thought of 'restify' as something you would pour something in some other format, say html, into and get ReST out .... I like being a restifarian. Pyrite pleases the geologist in me. Laura

from comp.lang.python.announce -- Helix encryption
by Laura Creighton 16 Nov '03

This might be interesting to use as a pypy performance test, if we can get the python version acceptably fast. ------- Forwarded Message From: "James Makela" <jamesm249(a)comcast.net> Newsgroups: comp.lang.python.announce Subject: ANN: xhelix encryption/authentication module There was recently an article named "Helix: Fast Encryption and Authentication" by Niels Ferguson and Bruce Schneier, published in the Nov 2003 issue of Dr Dobbs Journal. In it was a module written in python to implement this encryption method. This module works very well, but is too slow to be used in any practical application. xhelix is a python C extension implementing Helix encryption and authentication. It is used in the same way as the Helix module descibed in the article, but runs many, many times faster. The project resides at: http://sourceforge.net/projects/xhelix/ The current version is 1.0 and is released under LGPL if you have any questions, mailto: jamesm249(a)users.sourceforge.net - -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html ------- End of Forwarded Message

Introducing Richard Emslie
by Christian Tismer 10 Nov '03

10 Nov '03

Dear PyPy-bakers, how do I write a nice introduction? Here a try... Last time in Charleroix, I met Richard Emslie, right before my Stackless talk. He was quite interested and later implemented auto-scheduling for SLP 3.0. He is working for the Dublin department of a larger reinsurance company, which makes heavy use of Python. Last week, I was invited to Dublin as a consultant, in order to do training for them on how to build Python, extensions and GUIs under Windows. It was a very pleasant experience, both the department and working with Richard. There is a lot of interest to see PyPy succeed, and he may be sent to the next PyPy sprint, which I would appreciate very much. Richard is new to PyPy, but very interested and learning quickly. He has tough knowledge of Python and knows C very well, working under Linux most of the time. Still I'm not sure how to do a nice introduction, but that's all, folks. I'll leave the rest to Richard. cheers - chris -- Christian Tismer :^) <mailto:tismer@tismer.com> Mission Impossible 5oftware : Have a break!

How do you > do global optimizations like register allocation? It is central to Psyco, the Python just-in-time specializer (http://psyco.sourceforge.net) whose techniques we plan to integrate with PyPy. Unlike other environments like Self, which collects execution profiles during interpretation and use them to recompile whole functions, Psyco has no interpretation stage: it directly emits a basic block and run it; the values found at run-time trigger the compilation of more basic blocks, which are run, and so on. So each function's machine code is a dynamic network of basic blocks which are various specialized versions of a bit of the original function. This network is not statically known, in particular because basic blocks often have a "switch" exit based on some value or type collected at run-time. Every new value encountered at this point triggers the compilation of a new switch case jumping to a new basic block. We will also certainly consider Self-style recompilations, as they allow more agressive optimizations. (Register allocation in Psyco is done using a simple round-robin scheme; code generation is very fast.) > That would be great!

Well, as the C++ API is nice and clean it is probably simpler to bind it directly to Python. We would probably go for Boost-Python, which makes C++ objects directly accessible to Python. But nothing is sure about this; maybe driving LLVM from LLVM code is closer to our needs. Is there a specific interface to do that? Is it possible to extract from LLVM the required code only, and link it with the final executable? In my experience, there are a few limitations of C that require explicit assembly code, like building calls dynamically (i.e. the caller's equivalent of varargs). A bientot, Armin.

Are how about Numarray and how that will be different from Numeric? This then segues into scientific uses of Python. Educational uses of Python is always nice.
