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 directl...

ok well i was going through trying to install wine, but couldnt get it to install or anything, so then i found a script to install it, it installs, but idk what is wrong now. i type "/usr/local/bin/winecfg" into my terminal to configure wine, and i get this "Application tried to create a window, but no driver could be loaded. The X11 driver is missing. Check your build!

Hi All, Currently I am investigating how interesting OGG is for me. The most important requirements are: - Decoding on embedded hardware, ARM7 or ARM9. - Mixing multiple audio streams/files on embedded hardware First of all how difficult is it to decode OGG on an ARM7/9 processor? I read that OGG decoding needs floating point support? Secondly I would like to know how many MIPS are needed to

...c part of (P). Now consider (M) itself and specialize it statically for its first argument (I) for optimization. The result is efficient low-level code that can dynamically instrument and compile any user program (P). This efficient low-level code can also be written by hand; it is what I did in Psyco. Now that I know exactly how such code must be written it is not difficult to actually generate it out of the regular Python source code of (I), i.e. PyPy. We won't actually write (M). A bientot, Armin.

I have been comparing R with other languages and systems. One peculiar feature of R is there is no scalar. Instead, it is just a vector of length one. I wondered how much performance penalty this deign cause, particular in situations with many scalars in a program. Thanks.

I found this little post over at the Slicehost forums (http:// forums.slicehost.com): http://www.alrond.com/en/2007/jan/25/performance-test-of-6-leading- frameworks/ Speed test between Rails (1.1.6 and 1.2.1), Django (w/wo psyco and threaded/pre-forked), TurboGears, Symfony, Catalyst etc. Nginx as the front-end for all of them. Even though they are simulated numbers I thought it might be interesting to discuss. Besides the fact that from these tests Django seems to be whooping serious butt on all fronts, it shows th...

The topic of Ra and jit has come up on this list recently (see http://www.milbo.users.sonic.net/ra/index.html) so I thought people might be interested in this little demo. For it I used my machine, a 3-year old laptop with 2Gb memory running Windows XP, and the good old convolution example, the same one as used on the web page, (though the code on the web page has a slight glitch in it). This

I recently coded a recursion algorithm in R and ir ran a few days without returning any result. So I decided to try a simple case of computing binomial coefficient using recusrive relationship choose(n,k) = choose(n-1, k)+choose(n-1,k-1) I implemented in R and Fortran 90 the same algorithm (code follows). The R code finishes 31 minutes and the Fortran 90 program finishes in 6 seconds. So the
