[ANN] Python courses this Spring
by wesley chun 22 Mar '07

22 Mar '07

I'll be giving a variety of Python courses this Spring. Daytime courses are for visitors and locals who need Python training in the shortest amount of time possible via consecutive workdays. Python is certainly gaining momentum as our February course filled up completely! Although I had planned on scheduling the same set to be taught in November, it is likely that these May daytime sessions are the last ones of 2007. In contrast, I'm experimenting with a *weekly evening* course in Silicon Valley designed mainly for locals. It represents a viable alternative to those who cannot take time off during the week as well as being more budget-friendly, as I am partnering with a local community college (Foothill) to offer this course. Class takes place on the main campus and you must register through the college to attend. For more information, such as cost and other course details, see the corresponding websites below.

itools 0.15.2 released
by "J. David Ibáñez" 22 Mar '07

22 Mar '07

itools 0.15.2 (2007/03/22) ========================== itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.http itools.uri itools.cms itools.i18n itools.vfs itools.csv itools.ical itools.web itools.datatypes itools.rss itools.workflow itools.gettext itools.schemas itools.xhtml itools.handlers itools.stl itools.xliff itools.html itools.tmx itools.xml This release brings tons of changes, many more than it is reasonable to do for just a minor version bump. Highlights: - The speed of the iCalendar handler has been radically improved, specifically for searches. We have added reverse indexes and now the method "search" offers the same API as the CSV handler. - A new module, "itools.i18n.locale", has been added to provide support for locale information like dates. - The database system for "itools.cms" has been re-worked. The code is cleaner, faster and more robust. - There have been major user interface improvements in "itools.cms". Most notably, a drop-down menu has replaced the tabs. There is also a new menu in the left column called "Main Menu", with links to the most frequently used views. Other improvements involve the folder's browse view (sort by size, localized last modification time), and the JavaScript calendar widget, which is multilingual now. - The Wiki and Calendar objects of "itools.cms" have been improved. The first has a new "export to PDF" feature and has a generally better user interface. The second has an improved weekly view. - A new object has been added to "itools.cms": Web-Site. Its intended purpose is to be the root of a public (extranet) or private (intranet) site; so a single "itools.cms" instance may host several web sites, with a shared user database. - The user management and control access interfaces of "itools.cms" have been re-worked. And now we have two security policies: intranet or extranet. Also, now users have the fields "firstname" and "lastname" (instead of just one field for the fullname). - The API of "itools.cms" has been tweaked to make easier several tasks, most notably to define custom skins, to use the "table" widget, and to validate forms. Credits: - Luis Belmar Letelier helped fixing bugs; - Hervé Cauwelier worked on "itools.cms" (Wiki, CSS), got the API of "itools.web" working as documented, and fixed bugs; - Nicolas Deram worked on "itools.ical", "itools.cms.ical", and fixed bugs; - J. David Ibáñez worked on the user interface of "itools.cms" and the related programming interface, on the performance of "itools.ical" and fixed bugs.

ANN: Schevo 3.0
by Matthew Scott 21 Mar '07

21 Mar '07

Orbtech, L.L.C. and the Schevo team are pleased to announce the availability of Schevo version 3.0. After nearly two years of refinement, the third generation of Schevo, a next-generation DBMS for Python, has been deemed ready to be stripped of "beta" status. Don't let that fool you though: Schevo has been in production use during that entire time as its development is driven by real-world use cases. Get started with Schevo right away: http://schevo.org/wiki/SchevoGettingStarted Learn more about Schevo and related projects: http://schevo.org/ What is Schevo? Rapid Development: It's easy and fun to create even the most complex of databases. Easily write and understand schema syntax. Quickly place required initial data directly in your schema; use the same syntax to create sets of sample data for development use. Rich Schema Definition: Write database schemata using concise, easy-to-read Python code. Your schema will describe not only database structure, but also all transactions and rules that ensure database integrity. Automated Schema Evolution: Deploy a Schevo database and use it to store valuable data, then easily make further changes to the structure of the database. Use Schevo's tools to help restructure a database and safely migrate data from one schema version to the next. Transaction Based: Schevo protects your data. Use transactions to make all changes to a Schevo database (it's the only way it allows you to!), and you can trust Schevo to ensure that your database is left in a consistent state at all times. User Interface Generation: User interface code takes advantage of the richness of your database schema. Use a full-featured database navigator to interact with your database without writing a single line of code outside your database schema. Build customized UIs using Schevo-aware widgets and UI tools.

by Irmen de Jong 20 Mar '07

20 Mar '07

I'm happy to announce Pyro 3.6 -- Python's own powerful remote method invocation technology! You can get it via http://pyro.sourceforge.net, then go to the SF project homepage download area. It has many new features and improvements over Pyro 3.5, which was released more than a year ago. (Sorry about the glacial update rate) Most important new stuff: - python 2.5 compatibility fixes - multithreading stability fixes - mobile code race condition fixes - a few new examples - various stability improvements and other fixes - new looks for the manual The full list is far too long to include here. Please view it online: http://pyro.sourceforge.net/manual/12-changes.html#latest Have fun, and thanks for your interest, support, and feedback! --Irmen de Jong ---> What is Pyro? Pyro is an acronym for PYthon Remote Objects. Pyro is an advanced and powerful Distributed Object Technology system written entirely in Python, that is designed to be very easy to use. It is extremely easy to implement a distributed system with Pyro, because all network communication code is abstracted and hidden from your application. You just get a remote Python object and invoke methods on the object on the other machine. Pyro offers you a Name Server, an Event Service, mobile objects, remote exceptions, dynamic proxies, remote attribute access, automatic reconnection, a very good and detailed manual, and many examples to get you started right away.
