== Meeting: Wednesday, May 16, 2007 == * Time: 6-8 PM * Location: bivio Software, Inc., 28th and Iris, Boulder, CO. Above Hair Elite in Suite S. There is abundant parking. This coming Wednesday, May 16, we have two researchers from the National Center for Atmospheric Research (NCAR) in Boulder presenting how they use Python as part of their weather research: * Joe VanAndel will present "Linux and Python at 20,000 Meters Above the Sea", a NCAR/CNES dropsonde project that investigated the hurricane formation zone off the west coast of Africa. After introducing the driftsonde project, he will discuss how Linux was used in the on-board gondola computer and explain how using the Python programming language facilitated reprogramming the gondola in the middle of a flight. * Mary Haley will present "Python Frameworks for Geoscience Visualization and Analysis". PyNGL and PyNIO are Python interfaces to a widely popular software package called the NCAR Command Language (NCL) for the access, analysis, and high-quality quantitative visualization of geoscientific data. Mary will briefly discuss NCL's history, and then segue into why Python was chosen for developing the next generation framework tools for file input/output, analysis and visualization. She will show an animation from a new high resolution Community Climate System Model (CCSM) run computed on a T341 grid (1024 points in longitude by 512 points in latitude) that was created using NCAR's new Python interfaces to NCL and other post production utilities. Some upcoming events you might be interested in: * Front Range Code Camp. Saturday, May 19. This would be an good setting to have a Python code jam. * Pythoneers Meeting, June 18. Steve Bethard from CU will present on Python and Natural Language Processing. * SciPy 2007 Conference, Aug 16-17. Held on the CalTech campus in Pasadena, CA, Aug 16-17. The deadline for abstracts is June 29. We will have food & drink available as usual. This includes our usual free beer! Hope to see you there Wednesday!

by eGenix Team: M.-A. Lemburg 10 May '07

10 May '07

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Database Interface Version 3.0.0 Our commercially supported Python extension providing ODBC database connectivity to Python applications on Windows and Unix platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Distribution-3.0-GA.html ________________________________________________________________________ ABOUT The mxODBC Database Interface allows users to easily connect Python applications to just about any database on the market today - on both Windows and Unix platforms in a highly portable and convenient way. This makes mxODBC the ideal basis for writing cross-platform database programs and utilities in Python. mxODBC is included in the eGenix.com mxODBC Distribution for Python, a commercial part of the eGenix.com mx Extension Series, a collection of professional quality software tools which enhance Python's usability in many important areas such as ODBC database connectivity, fast text processing, date/time processing and web site programming. The package has proven its stability and usefulness in many mission critical applications and various commercial settings all around the world. * About Python: Python is an object-oriented Open Source programming language which runs on all modern platforms (http://www.python.org/). By integrating ease-of-use, clarity in coding, enterprise application connectivity and rapid application design, Python establishes an ideal programming platform for todays IT challenges. * About eGenix: eGenix is a consulting and software product company focused on providing professional quality services and products to Python users and developers (http://www.egenix.com/). ________________________________________________________________________ NEWS mxODBC 3.0 has received a large number of enhancements and supports more ODBC drivers than ever. Some highlights: * mxODBC has been ported to Python 2.5. * We've worked a lot on the Unicode support and made it more robust, especially on Unix platforms where the ODBC Unicode support has stabilized over the last few years. You can now issue commands using Unicode and exchange Unicode data with the database in various configurable ways. * We've also added a methods to give you more control of the connections and cursors as well as the .callproc() method for calling stored procedures that mxODBC 2.0 was missing. * Multiple result sets via the .nextset() are also supported, so working with stored procedures should be a lot easier now. * Another highlight is the added support for Python's datetime module types and the option to use strings for date/time processing (e.g. to be able to use timezones in timestamps if that's supported by the database). * Python's decimal module is now supported as well and it's possible to configure mxODBC to return Decimal types for numeric values. * mxODBC 3.0 received full 64-bit support, so that you can run mxODBC (and all other mx Extensions) on e.g. AMD64 platforms. * We've switched from the old distutils wininst installer to the new MSI installer for the Windows Python 2.5 build. This gives you a lot more options for automatic installs, including unattended installs. See http://www.python.org/download/releases/2.5/msi/ for details. Note that in order to avoid confusion, we've decided to rename the eGenix.com mx Commercial Distribution to eGenix.com mxODBC Distribution with this release. The commercial distribution has always only contained the mxODBC package, so this was an obvious step to clarify things for our users. As always we are providing pre-compiled versions of the package for Windows, Linux, Mac OS X, FreeBSD and Solaris as well as sources which allow you to install the package on all other supported platforms. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing the package can be found at: http://www.egenix.com/products/python/mxODBC/ IMPORTANT: In order to use the eGenix mx Commercial package you will first need to install the eGenix mx Base package which can be downloaded from here: http://www.egenix.com/products/python/mxBase/ ________________________________________________________________________ UPGRADING Please note that mxODBC 2.0 does not support Python 2.5 on 64-bit platforms due to the Py_ssize_t changes in the Python C API. You are encouraged to upgrade to the new mxODBC 3.0 release, if you plan to deploy on 64-bit platforms and use Python 2.5 as basis for your applications. ________________________________________________________________________ LICENSES & COSTS This release brings you all the new features and enhancements in mxODBC that were previously only available in through our mxODBC Zope Database Adapter. Like the Zope product, mxODBC now requires that you install a license in order to use it. You can request 30-day evaluation licenses by writing to sales(a)egenix.com, stating your name (or the name of the company) and the number of eval licenses that you need. We will then issue you licenses and send them to you by email. Please make sure that you can receive ZIP file attachments on the email you specify in the request, since the license files are send out as ZIP attachements. _______________________________________________________________________ SUPPORT Commercial support for these packages is available from eGenix.com.

SQLObject 0.9.0
by Oleg Broytmann 10 May '07

10 May '07

Hello! I'm pleased to announce the 0.9.0 release of SQLObject, the first stable release of the 0.9 branch. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.9.0 News and changes: http://sqlobject.org/News.html What's New ========== Features & Interface -------------------- * Support for Python 2.2 has been declared obsolete. * Removed actively deprecated attributes; lowered deprecation level for other attributes to be removed after 0.9. * SQLite connection got columnsFromSchema(). Now all connections fully support fromDatabase. There are two version of columnsFromSchema() for SQLite - one parses the result of "SELECT sql FROM sqlite_master" and the other uses "PRAGMA table_info"; the user can choose one over the other by using "use_table_info" parameter in DB URI; default is False as the pragma is available only in the later versions of SQLite. * Changed connection.delColumn(): the first argument is sqlmeta, not tableName (required for SQLite). * SQLite connection got delColumn(). Now all connections fully support delColumn(). As SQLite backend doesn't implement "ALTER TABLE DROP COLUMN" delColumn() is implemented by creating a new table without the column, copying all data, dropping the original table and renaming the new table. * Versioning - see http://sqlobject.org/Versioning.html * MySQLConnection got new keyword "conv" - a list of custom converters. * Use logging if it's available and is configured via DB URI. * New columns: TimestampCol to support MySQL TIMESTAMP type; SetCol to support MySQL SET type; TinyIntCol for TINYINT; SmallIntCol for SMALLINT; MediumIntCol for MEDIUMINT; BigIntCol for BIGINT. Small Features -------------- * Support for MySQL INT type attributes: UNSIGNED, ZEROFILL. * Support for DEFAULT SQL attribute via defaultSQL keyword argument. * cls.tableExists() as a shortcut for conn.tableExists(cls.sqlmeta.table). * cls.deleteMany(), cls.deleteBy(). Bug Fixes --------- * idName can be inherited from the parent sqlmeta class. * Fixed a longstanding bug with .select() ignoring 'limit' parameter. * Fixed a bug with absent comma in JOINs. * Fixed sqlbuilder - .startswith(), .endswith() and .contains() assumed their parameter must be a string; now you can pass an SQLExpression: Table.q.name.contains(func.upper('a')), for example. * Fixed a longstanding bug in sqlbuilder.Select() with groupBy being a sequence. * Fixed a bug with Aliases in JOINs. * Yet another patch to properly initialize MySQL connection encoding. * Fixed a minor comparison problem in test_decimal.py. * Fixed a bug in SQLRelatedJoin that ignored per-instance connection. Docs ---- * Added documentation about 'validator' Col constructor option. * Added an answer and examples to the FAQ on how to use sqlmeta.createSQL. * Added an example on how to configure logging. * More documentation about orderBy. For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

ANN: parley 0.2
by Jacob Lee 09 May '07

09 May '07

Release Announcement: PARLEY version 0.2 PARLEY is an API for writing Python programs that implement the Actor model of distributed systems, in which lightweight concurrent processes communicate through asynchronous message-passing. Actor systems typically are easier to write and debug than traditional concurrent programs that use locks and shared memory. PARLEY can run using either traditional native threads or user-space threads (i.e. the "tasklets" implemented by Stackless Python). A program written using PARLEY can choose between the two by changing a single line of code. Code samples, documentation, and source code can be found at the PARLEY home page: http://osl.cs.uiuc.edu/parley/ PARLEY is licensed under the LGPL. -- Jacob Lee <artdent(a)freeshell.org>
