[ANN] Release 0.64.1 of Task Coach
by Frank Niessink 11 Jun '07

11 Jun '07

Hi, I'm pleased to announce release 0.64.1 of Task Coach. This is a bug fix release that should fix the following bugs: * Task Coach would complain about an error when closing the application. This was due to a missing package in the Windows executable distribution. * On Linux, Task Coach was not very helpful when the taskcoachlib package is installed for a different python version than the one the user is starting Task Coach with. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org https://sourceforge.net/projects/taskcoach/ In addition to the source distribution, packaged distributions are available for Windows XP, Mac OSX, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

New mailing list mirrors
by sebulba 10 Jun '07

10 Jun '07

Hi all, I created two new google groups to mirror the activity of python-dev and python-3000: * http://groups.google.com/group/python-3000 * http://groups.google.com/group/python-dev2 There are many mirrors out there, but none of them lets you post to a thread. With google groups you can just hit "reply" on the message you want to reply to, and that's it. No need to send an email to the group (although you still need to register your email with python mailing list). Supports searching, tree-view, list-view, fixed/proportional font, tracking of read/unread messages, etc. Enjoy. -tomer

Calling Usergroup Organizers (and Wannabees)
by Jeff Rush 07 Jun '07

07 Jun '07

We'd like to strengthen and raise the visibility of Python usergroups and foster the creation of new ones, by sharing the valuable experiences of those leaders around the community who make it happen. [1] One step is to make others more aware of what is already happening, perhaps in their own neighborhood re Python meetings. I've created a shared blog and invite organizers of existing groups to send me their email address to get privs to post to it. http://python-groups.blogspot.com/ Because these postings will be distributed far and wide, a posting should be of interest to those who did not attend but are considering doing so, or that might be instructive to organizers in other cities. An overview of what was covered in a past meeting, or an announcement with substance on what an upcoming meeting is going to be about are good postings. A simple date and local address, or that the pizza was good last week, is not. ;-) [2] A second step is to encourage and support new organizers in forming groups in their area. There is a strong demand for such meetings, but many are uncertain how to go about it. Therefore I've created a new mailing list on which experienced and new organizers can share tips on getting started, whether about getting the word out, finding a place to meet or getting interesting speakers. http://mail.python.org/mailman/listinfo/group-organizers Those of us with a history of involvement in a usergroup often forget that many people have never attended a usergroup meeting, or lack experience in running one, so let's help strengthen this aspect of Python. We could use some videos or photos of group meetings as well, posted to youtube.com/flickr.com and the link emailed to me for use. I'd also like to reach out to the existing, successful usergroups and ask them to spread the word about their efforts by being interviewed by Ron Stephens on Python411, and/or writing up an article on how your group got started for Tennessee Leeuwenburg of _The Python Papers_. Even a simple "what a typical meeting is like in my area" is helpful. http://www.awaretek.com/python/index.html http://pythonpapers.cgpublisher.com/ It would be especially interesting to see how usergroups operate in various countries around the world, and perhaps help bring together these regions. In closing, please, for existing usergroups as well as new ones coming online, update the entry for your group on the roster of Python usergroups. http://wiki.python.org/moin/LocalUserGroups Jeff Rush Advocacy Coordinator

ANN: LOLPython 1.0
by Andrew Dalke 04 Jun '07

04 Jun '07

Following along with the current lolcat fad, and taking inspiration from lolcode, I've implemented LOLPython. For details and downloads see http://www.dalkescientific.com/writings/diary/archive/2007/06/01/lolpython.… Here's an example implementation of a Fibonacci number generator SO IM LIKE FIBBING WIT N OK? LOL ITERATE FIBONACCI TERMS LESS THAN N /LOL SO GOOD N BIG LIKE EASTERBUNNY BTW, FIBONACCI LIKE BUNNIES! LOL U BORROW CHEEZBURGER U BORROW CHEEZBURGER I CAN HAZ CHEEZBURGER HE CAN HAZ CHEEZBURGER WHILE I CUTE? I AND HE CAN HAZ HE AND I ALONG WITH HE IZ HE BIG LIKE N? KTHXBYE U BORROW HE The lolpython.py runtime converts LOLPython to Python. def FIBBING ( N ) : 'ITERATE FIBONACCI TERMS LESS THAN N' assert N >= 0 # BTW, FIBONACCI LIKE BUNNIES! LOL yield 1 yield 1 I = 1 HE = 1 while 1: I , HE = HE , I + HE if HE >= N : break yield HE and by default exec's the translated code. You might also be interested looking at the code because I use PLY for tokenization and translate the token stream into Python code which is then exec'ed. The neatest part was making the exec'ed code act like it was in __main__ using module_name = "__main__" python_s = to_python(lolpython_s) m = types.ModuleType(module_name) sys.modules[module_name] = m exec python_s in m.__dict__ which is a trick others might use when implementing interesting import hooks. LOLPython, at http://www.dalkescientific.com/writings/diary/archive/2007/06/01/lolpython.… Please note that LOLPython does not implement the lolcode standard language. While I was influenced by some of the language I wanted something which was semantically equivalent to Python, including support for classes, exceptions and the yield statement. For an implementation of lolcode in Python (and also using PLY) see sjlol at: http://lolcode.com/implementations/sjlol and a full list of implementations at http://lolcode.com/implementations/implementations including IDE support in Visual Studio.

Pythomnic 5.0 - platform for building reliable network services in Python
by dmitry＠targeted.org 04 Jun '07

04 Jun '07

Pythomnic is a platform for building non-stop middleware around a set of network services. It allows changing source code and configuration on the fly without interrupting the live service. Pythomnic modules can be invisibly migrated from one server to another for redundancy or load balancing. Such middleware can take as much business logic as necessary, from being a simple adapter to an integration platform. New in version 5.0: * RPC channels are protected with cryptographic HMAC signature. * Client request timeouts are rigorously enforced and can be queried from the application code using new pmnc_time_left construct. * Centralized two-phase lock manager can be deployed and used for network-wide mutual exclusion with a pmnc_lock construct. * New shell-like interface allows connecting to a service using telnet and sending it commands for controlling external equipment, software or the service itself. + More documentation http://www.pythomnic.org/
