Adding persistence of objects to a derived Python Queue class partially addresses this issue. We use the DyBASE embedded object oriented database to persist queues items in files. If needed, you can

- python April 02, 2012 ### Revisiting Perl and Python's Speed I was really surprised to see the discussion that was generated as the result of my previous post comparing the speed of Python and Perl . Many people much wiser than me posted a lot of valuable comments and suggestions, and two people were kind enough to post total rewrites of my routines which (to nobody's surprise) were much faster than the codes I wrote. A few people (both here on the blog and through other discussion) raised legitimate

### Thursday, August 27, 2009 ## Inside the "Inside the Python GIL" Presentation On June 11, 2009 I gave a presentation about the inner workings of the Python GIL at the Chicago Python user group meeting. To be honest, I always expected the event to be a pretty low-key affair involving some local Python hackers and some beers. However, the presentation went a little viral and I've received a number of requests to get the code modifications I made to investigate thread behavior--especially the traces that

# The History of Python A series of articles on the history of the Python programming language and its community. ## Saturday, May 12, 2018 ### The origins of pgen David Beazley's talk at US PyCon 2018, about parser generators, reminded me I should write a bit about its history. Here's a brief brain dump (maybe I'll expand later). There are actually two pgens. The original, in C, and a rewrite in Python, under lib2to3/pgen2. I wrote both. The original was actually the first code I wrote for Python. Al
