Tornado this month, PyCon Dress Rehearsal next month at PyGTA
by Mike C. Fletcher Jan. 13, 2010

Jan. 13, 2010

We've got two fun months of PyGTA lined up. This month we'll be exploring the world of the Tornado web server (http://www.tornadoweb.org), next month we've got a 3-speaker dress rehearsal for PyCon 2010. The details: Tuesday, 19th January, 2010, 7pm Tornado Hacking Tornado <http://www.tornadoweb.org> (http://www.tornadoweb.org) is an Open Source non-blocking web server. It's used by FriendFeed to provide lightweight "server push" to the browser on the scale of thousands of simultaneous clients per server. We'll explore how to code with Tornado, and in particular, how to write callback-based asynchronous code. We'll also look at how server-push (polling, long-polling and streaming variants) works works on both the server and client side. If people are interested, we can also look at the REST-based CouchDB (asynchronous) client, or do some collaborative hacking on the ChatTrack (conference feedback tool) or TorChannels (generic push channels for Tornado) codebases. Tuesday, 16th February, 2010, 7pm (gather) PyCon Dress Rehearsal 3 PyCon 2010 Presenters will do a dress rehearsal of their PyCon 2010 presentations <http://us.pycon.org/2010/conference/talks/> just before they head down to Atlanta. All three talks are targeting beginner or general audiences, so feel free to bring along your new Pythonista friends. We have 3 PyCon previews scheduled: * Think Globally, Hack Locally - Teaching Python in Your Community — Leigh Honeywell * What We've Learned From Building Basie — Greg Wilson * Debating 'til Dawn: Topics to keep you up all night — Mike Fletcher We will give each presenter 20 minutes and then as much question/answer and feedback time as they want. At PyCon they'll only get 30 minutes total, but we want to give them as much feedback as possible so they can polish their presentation for the larger audience. We'll start the presentations at 7:30 (sharp) at Linux Caffe. If you bring a laptop, there will be an immediate feedback channel available. Directions to the venue, RSS feeds of upcoming events, and all the details are available on the web site: http://www.pygta.org Enjoy yourselves, Mike -- ________________________________________________ Mike C.

Python-URL! - weekly Python news and links (Jan 13)
by Gabriel Genellina Jan. 13, 2010

QOTW: "... if I want to know something new (be it a computer language or anything else, such as economics, history, science) I skip the introductory material and go directly to the discussion, to the issues.

by David Beazley Jan. 11, 2010

Jan. 11, 2010

Python Concurrency Workshop, v2.0 January 14-15, 2010 Chicago, Illinois http://www.dabeaz.com/chicago/concurrent.html *** Last chance to register. There are still a few slots available as well as a deeply discounted student rate. *** Join David Beazley, author of the Python Essential Reference, for an in-depth workshop on concurrent programming techniques and idioms. This workshop, designed for more experienced Python programmers, covers threads, synchronization, message passing, multiprocessing, distributed computing, coroutines, asynchronous I/O and other related topics with an eye towards writing programs that can run on multiple CPU cores, clusters, or distributed systems. A major theme of the workshop is to explore and understand different programming techniques, their associated performance properties, and other tradeoffs. You'll definitely walk away with new insight and a better understanding of how different parts of Python work under the covers. Workshop attendance is strictly limited to six people. More information, including a detailed topic index, is available at: http://www.dabeaz.com/chicago/concurrent.html

Release of version 0.21.0 of CodeInvestigator
by hans moleman Jan. 11, 2010

Jan. 11, 2010

CodeInvestigator 0.21.0 was released on January 11. Bug changes: - In Windows, a shortcut was only created when an Administrator did the install: Administrator privileges are no longer required. Functionality changes: - Tabs styling. - Drive letters show in the sub-menu under Windows. - 'About' in Menu - Changed the code background colors. - Firefox doesn't need to be closed down before a restart of CI. You need Python 2.6 and Firefox for CodeInvestigator. CodeInvestigator is a tracing tool for Python programs. Running a program through CodeInvestigator creates a recording. Program flow, function calls, variable values and conditions are all stored for every line the program executes. The recording is then viewed with an interface consisting of the code. The code can be clicked: A clicked variable displays its value, a clicked loop displays its iterations. You read code, and have at your disposal all the run time details of that code. A computerized desk check tool and another way to learn about your program. http://sourceforge.net/project/showfiles.php?group_id=183942
