i just had the book FLOWS reccomeenmded to me
by Laura Creighton April 13, 2004

April 13, 2004

this is part of its amazon review: the book has an excellent, though smaller, section on enhancing personal creativity. To those who seek to be more creative, a series of suggestions on how to implement these suggestions into everyday life is presented, with the note; "Even though personal creativity may not lead to fame and fortune, it can do something that from the individual's point of view is even more important: make day-to-day experiences more vivid, more enjoyable, more rewarding.… [View More]

Announcing new designs for Leo
by Edward K. Ream April 10, 2004

April 10, 2004

Laura asked me to make an announcement here of a set of new designs for Leo. These designs are now on Leo's SourceForge site at: http://sourceforge.net/forum/forum.php?thread_id=1056336&forum_id=10228 This is a technical design of three major new features to be added to Leo, probably in version 4.2: - @file-thin will allow Leo to be used more easily in a multi-user environment. With @file-thin one could conceivably manage all of Python's or PyPy's code base with a single .leo file, … [View More]

Proof that pypy is feasible
by Edward K. Ream April 10, 2004

April 10, 2004

Hello all, "Rumors have it that the secret goal is being faster-than-C which is nonsense, isn't it?" My thinking about this has changed since then as the result of reading the following two excellent HP tech reports: http://www.hpl.hp.com/techreports/1999/HPL-1999-77.pdf http://www.hpl.hp.com/techreports/1999/HPL-1999-78.pdf These papers should convince any skeptic that PyPy is feasible. The first report is a summary; the second provides more details. I won't discuss them in detail; they … [View More]are clear enough. Here is the key sentence from the abstract of the first paper: "Contrary to intuition, we demonstrate that it is possible to use a piece of software to improve the performance of a native, statically optimized program binary, _while it is executing_." (emphasis in original). The phrase "contrary to intuition" is apt". One would have thought that interpreting opcodes in software and maintaining a cache (also in software) would be way too expensive. Apparently not. It is this surprise that makes these papers so important. If Dynamo can optimize the binary output of compilers at run time, totally in software with no assist whatever from the compilers or any other part of the OS, then a similar approach certainly can certainly optimize either Python's C interpreter main loop or Python's byte codes directly. Whether the specific approach discussed in these papers would be of value is something for PyPy's designers to decide. The more people are convinced that PyPy is feasible, the more people will be inspired to contribute to it. Edward P.S. I regretted being able to see you all at PyCon this March. I would have been most interested in the PyPy papers. I wonder if the various PyPy authors would mind sending me notes of their presentation? I did pay for the conference; I just was not able to attend. P.P.S. Iirc I found these reports after reading about "code morphing" and doing a bit of googling. I don't think I found about them from here :-) P.P.P.S. In the next several weeks I shall add the so-called @file-thin feature to Leo. This will allow Leo to be used in highly cooperative environments managed by cvs or subversion or whatever. In the short term, this is likely to be the extent of my contribution to the PyPy project. P.P.P.S. Think what might happen if hardware used a similar caching scheme... EKR -------------------------------------------------------------------- Edward K.

It's their problem :-) grin, but, indeed, the reason to ask why is to figure out a way to nail down some safe, valued, apprecuiated space to create in at all. I'm not interested in 'creating in the cracks' -- having the main part of my life go on doing things I despise, and just dreaming of the evenings, the weekends, the vacation time, to get me the … [View More]

python/pypy hacking before EuroPython
by holger krekel April 8, 2004

April 8, 2004

Hi PyPy devers, the other day Armin and me talked about the next PyPy sprint. Due to our recent inhuman efforts negotiating with the EU actual coding and planning sprints suffered. Thus we think it's hardly possible to do a separate PyPy sprint before the one at EuroPython. But as a remedy the idea now is to do a 3+7 day coding sprint before EuroPython in Goetheburg/Sweden: 28th of May till 30th of May: Free Python hacking 31st of May till 6th of June: PyPy sprint 7th of … [View More]

Here is IBM's announcement: http://www-306.ibm.com/chips/news/2004/0331_power.html and Wired's blurb on it: http://www.wired.com/news/infostructure/0,1377,62885,00.html?tw=wn_tophead_2 What would you do if you could design ideal h/w support for python or a python VM?
