Release 0.3 of Evoque Templating
by Mario Ruggier Sept. 6, 2008

Sept. 6, 2008

Happy to announce release version 0.3 of the Evoque Templating engine for python. Other than the bug fixes, a couple recent changes that are particularly worthy of mention are: - Significantly more dynamic In particular you can now do things like determine the base template of a template hierarchy chain dynamically at runtime -- how it is done boils down to just using a variable to select which template to to use as base template i.e. a template just declares an overlay directive such as $overlay{name=my_site_theme} and the runtime value of my_site_theme will determine which template will be overlaid. This can be a very nice way to manage a site theme as per user preferences. For further explanations, see: http://evoque.gizmojo.org/howto/site-template/ - Seamless integration with Pylons The code for using Evoque as the templating engine in a Pylons application is included in the distribution, and detailed description of the process is at: http://evoque.gizmojo.org/ext/pylons/ What is Evoque? Evoque is a lightweight full-featured generic text templating engine for python with sandbox-ability, versatility and simplicity as key feature priorities. In spite of its feature-richness, it has a small footprint (972 SLOC) and is very fast.

[ANN] pysqlite 2.5.0 released
by Gerhard Häring Sept. 5, 2008

Sept. 5, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 pysqlite 2.5.0 released ======================= I'm pleased to announce the availability of pysqlite 2.5.0. This is a release with major new features. Go to http://pysqlite.org/ for downloads, online documentation and reporting bugs. What is pysqlite? pysqlite is a DB-API 2.0-compliant database interface for SQLite. SQLite is a in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. pysqlite makes this powerful embedded SQL engine available to Python programmers. It stays compatible with the Python database API specification 2.0 as much as possible, but also exposes most of SQLite's native API, so that it is for example possible to create user-defined SQL functions and aggregates in Python. If you need a relational database for your applications, or even small tools or helper scripts, pysqlite is often a good fit. It's easy to use, easy to deploy, and does not depend on any other Python libraries or platform libraries, except SQLite. SQLite itself is ported to most platforms you'd ever care about. It's often a good alternative to MySQL, the Microsoft JET engine or the MSDE, without having any of their license and deployment issues. pysqlite can be downloaded from http://pysqlite.org/ - Sources and Windows binaries for Python 2.5, 2.4 and Python 2.3 are available. ======= CHANGES ======= - - Windows binaries are now cross-built using mingw on Linux - - import various fixes from Python 2.6 version - - Connection has new method iterdump() that allows you to create a script file that can be used to clone a database - - the docs are now built using Sphinx and were imported from Python 2.6's sqlite3 module - - Connection.enable_load_extension(enabled) to allow/disallow extension loading. Allows you to use fulltext search extension, for example ;-) - - Give the remaining C functions used in multiple .c source files the pysqlite_ prefix. - - Release GIL during sqlite3_prepare() calls for better concurrency. - - Automatically download the SQLite amalgamation when building statically. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIwZV3dIO4ozGCH14RAp1YAJwPIdgtCZY7E8YcDUjO/dzoAThblgCggfhs OATfXAb6JYXqb8eTadl9k74= =KU3f -----END PGP SIGNATURE-----

GPCE'08 Call for Participation
by Emir Pasalic Sept. 5, 2008

Sept. 5, 2008

< http://gpce08.gpce.org > Seventh International Conference on Generative Programming and Component Engineering (GPCE'08) Nashville, Tennessee (co-located with OOPSLA 2008) * Only Six Days Left for Early Registration * *** CALL FOR PARTICIPATION Generative and component approaches are revolutionizing software development similar to how automation and components revolutionized manufacturing. Generative Programming (developing programs that synthesize other programs), Component Engineering (raising the level of modularization and analysis in application design), and Domain-Specific Languages (elevating program specifications to compact domain-specific notations that are easier to write, maintain, and analyze) are key technologies for automating program development. GPCE provides a venue for researchers and practitioners interested in foundational techniques for enhancing the productivity, quality, and time-to-market in software development that stems from deploying standard components and automating program generation. In addition to exploring cutting-edge techniques for developing generative and component-based software, our goal is to foster further cross-fertilization between the software engineering research community and the programming languages community. GPCE 2008 will be co-located with OOPSLA, in Nashville, Tennessee. The GPCE technical program will take place on Oct. 19-20, before the OOPSLA technical program begins. Other GPCE events (workshops and tutorials) will run in parallel with OOPSLA events on Oct 21-23. GPCE'08 is sponsored by ACM SIGPLAN, in cooperation with ACM SIGSOFT. GPCE'08 proceedings published by ACM Press. For full conference program and the latest news, check the GPCE'08 web site (http://gpce08.gpce.org). **** REGISTRATION Registration for GPCE'08 is handled through the OOPSLA registration page (http://www.regmaster.com/conf/oopsla2008.html).

[ANN] final 2008 Python courses, San Francisco
by wesley chun Sept. 5, 2008

Sept. 5, 2008

Need to get up-to-speed with Python as quickly as possible? Come join me, Wesley Chun, author of Prentice-Hall's bestseller "Core Python Programming," for another comprehensive intro course plus a 1-day Internet programming course coming up in November in beautiful Northern California! I look forward to meeting you! (Comprehensive) Introduction to Python Mon-Wed, 2008 Nov 10-12, 9am-5pm Internet Programming with Python Sat, 2008 Nov 15, 9am-5pm courses can be taken separately or combined for a discounted price. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (COMPREHENSIVE) INTRODUCTION TO PYTHON Although this course may appear to those new to Python, it is also perfect for those who have tinkered with it and want to "fill in the gaps" and/or want to get more in-depth formal training. It combines the best of both an introduction to the language as well as a "Python Internals" training course. We will immerse you in the world of Python in only a few days, showing you more than just its syntax (which you don't really need a book to learn, right?). Knowing more about how Python works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer coming out of the gate. 3 hands-on labs each day will help hammer the concepts home. Come find out why Google, Yahoo!, Disney, ILM/LucasFilm, VMware, NASA, Ubuntu, YouTube, and Red Hat all use Python. Users supporting or jumping to Plone, Zope, TurboGears, Pylons, Django, Google App Engine, Jython, IronPython, and Mailman will also benefit! - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - INTERNET PROGRAMMING WITH PYTHON This is a one-day course with lecture and lab exposing attendees to FOUR distinct areas of Internet programming: * Network Programming using Sockets -- we introduce client/server architecture and how to program sockets using Python. * Internet Client Programming -- we learn how to use Python's standard library to create FTP, NNTP, POP3, and SMTP clients * Web Programming -- before you jump on all the web framework bandwagons, it's a good idea to learn basics and the basis of how all web servers deliver dynamic content back to the client browser to prepare you better when jumping to a full-stack web framework * Intro to Django -- a lightweight introduction to the Django web framework including whipping up a very simple blog application in 20min! - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - WHERE: near the San Francisco Airport (SFO/San Bruno), CA, USA WEB: http://cyberwebconsulting.com (click "Python Training") FLYER: http://starship.python.net/crew/wesc/flyerPP1combo.pdf LOCALS: easy freeway (101/280/380) with lots of parking plus public transit (BART and CalTrain) access via the San Bruno stations, easily accessible from all parts of the Bay Area VISITORS: free shuttle to/from the airport, free high-speed internet, free breakfast and regular evening receptions; fully-equipped suites See website for costs, venue info, and registration.
