[off topic] Python is taking over the world
by James C. Ahlstrom May 19, 2001

May 19, 2001

I was in my local (Sommerville, NJ) Borders book store last week and noticed that they stocked many Python books, most in multiple copies. It all added up to three feet of Python books. Great. The clincher was when I went to my YMCA, and saw that someone had posted a flyer offering tutoring in Math, Physics, Java and Python. Congratulations to Guido and all on this list. JimA

PyBench DictCreation (was Re: Performance compares)
by Tim Peters May 18, 2001

May 18, 2001

The worst percentage hit in both MAL's and Jeremy's pybench run was (here showing Jeremy's numbers, cuz I doubt anyone could reproduce MAL's <wink>): DictCreation: 87.80 ms 2.93 us +115.72% Assorted things do not account for it: the new overhead of linking and unlinking dicts into the gc list (at creation and destruction times) seems to account for no more than 2%; and the overhead due to using the slower lookdict (as opposed to lookdict_string) even less. Jeremy … [View More]

IPv6

It is too large for any individual to review in one chunk. 2. It gets quickly outdated. 3. It … [View More]

GC and ExtensionClass - a summary of the problem and a workaround
by skip＠pobox.com May 17, 2001

May 17, 2001

Over the past couple days I've included python-dev on various messages in an ongoing thread about a segmentation violation I was getting with the new PyGtk2 wrappers. With some excellent assistance from the GC maestro, Neil Schemenauer, I finally know what's going on and I have a simple workaround that lets me get back to work. Here's a summary of the problem. When defining ExtensionClass types, you need to create and initialize a PyExtensionClass struct. It looks something like so: … [View More]

FYI: MIT's dynamic language design panel now online
by Chris Ryland May 16, 2001

May 16, 2001

This talk is most entertaining! Highly recommended to you good folk, if only as a reinforcement of the good design principles embodied in Python (with the exception of print >> ;-). Jonathan Rees (an old Scheme/T hand) kept referring to Python whenever he wanted to give an example of a modern dynamic language (disclaiming a lot of knowledge about it). He mentioned it three or four times (usually positively), so it must be on the tip of his mind. -- Cheers! Chris Ryland Em Software, Inc. www.emsoftware.com
