28 Oct '05

Numarray is an array processing package designed to efficiently manipulate large multi-dimensional arrays. Numarray is modelled after Numeric and features c-code generated from python template scripts, the capacity to operate directly on arrays in files, arrays of heterogeneous records, string arrays, and in-place operation on memory mapped files. ========================================================================= Release Notes for numarray-1.4.1 II. BUGS FIXED / CLOSED 1339713 segfault when comparing string-array to self ========================================================================= Release Notes for numarray-1.4.0 I. ENHANCEMENTS 1. Speed improvement for numarray operators. The Python level hook mapping numarray operators onto universal functions has been moved down to C. 2. Speed improvement for string-array comparisons, any(), all(). String correlation is ~10x faster. 3. Better operation with py2exe to help it automatically detect the core numarray extensions to include in an installer. 4. scipy newcore compatible lower case type names (e.g. int32 not Int32) 5. scipy newcore 'dtype' keyword and .dtypechar attribute.

OSDC (Melbourne, Australia) open for registrations
by Jacinta Richardson 28 Oct '05

28 Oct '05

Registrations for Australia’s second Open Source Developers’ Conference are now open. Last year’s conference was a huge hit with 60 high quality talks running in three streams over three days. If you were not able to join us last year make sure you don’t miss out this year! The conference is running from Monday 5th – Wednesday 7th December 2005. If you register before Sunday 30th October you will receive a conference t-shirt and a $50 discount. You can register at http://www.osdc.com.au/registration/index.html OSDC is a grass roots, YAPC-style conference designed by developers for developers, covering open source languages, tools, libraries, operating systems, licences and business models. We’re booking 3 lecture rooms each day for the 3 days to hold a new set 60 different talks. Talks topics range from the safety of Perl’s Safe.pm, to rapid game development in Python, to using PHP for unorthodox applications, to utilizing Java’s Groovy in your next application. We also have talks on conference skills, database integration, digital forensics, Gumstix and Nagios. You can find the full list of speakers and talk titles at http://osdc2005.cgpublisher.com/session_descriptions.html Because there are so many good talks, you can be certain that there will be something that interests you in every talk session. Each day will start with a keynote by our excellent keynote speakers. These include Damian Conway, Jonathan Oxer, Richard Farnsworth (from the Australian Synchrotron) and Anthony Baxter. The rest of the day will be filled with up to 5 hours of talks and plentiful food breaks. Our catering choices should result in you being extraordinarily well fed throughout the days of the conference. There will also be several BOFs (yet to be organised), lots of opportunities to socialise, a semi-formal dinner, a partners’ programme and other usual conference stuff. If you have any other questions about what is happening, please don’t hesitate to ask: osdc-help(a)osdc.com.au I hope to see you there! jarich

by Nagappan 26 Oct '05

26 Oct '05

About LDTP: Linux Desktop Testing Project is aimed at producing high quality test automation framework. It uses the "Accessibility" libraries to poke through the application's user interface. Thanks to Sun and Accessibility team. Whats new in this release: * Testing Applications in localized languages using LDTP ('Nagappan' & 'Premkumar') The wait is over! Languages are no barriers for testing applications any more! We are proud to announce the localization support available with this release of LDTP which no other F/OSS test automation tool has ever provided till date. This version of LDTP lets you test applications in localized languages. The best part being not necessary to rewrite scripts for testing applications running in localized languages. Use existing script, follow the simple steps provided in the README file (Localization support section) and you have LDTP testing your application!! The current version of LDTP does not include testing of rendering of localized strings. Thanks to Karunakar (karunakar(a)indlinux.org) for helping us complete this work successfully. * New component functions: + 'sortcolumnindex' and 'sortcolumn' for table/tree-table objects. ('Shaheed') + 'getwindowlist' and 'getcomponentlist' ('Premkumar') + 'bindtext', 'getobjectinfo' and 'getobjectproperties' ('Nagappan') * Major Bug Fixes: + Proper error messages have been updated for easy debugging ('Nagappan') + 'selectrow' to select row based on number of matchings ('Shaheed') + 'doesrowexist' now performs an exact match ('Shaheed') + Crasher bug in menu.c relating to menu items has been fixed ('Nagappan') + Crasher bug in 'selectcalendardate' API has been fixed ('Premkumar') * Automation scripts: + Evolution 2.5.1 automation scripts for the following scenarios have been updated. Thanks to Patrick (patrick.gu(a)sun.com), Haip (harry.lu(a)sun.com), Nags (anagappan(a)novell.com), Premkumar (jpremkumar(a)novell.com) and Shaheed (sshaik(a)novell.com) for their wonderful contribution. - Compose mail with/without attachment - Copy/Delete/Move mail - Forward mail mail in different styles (Attachment/Inline/Quoted) - Search for mail based on - Subject or sender contains - Subject contains - Sender contains - Create/Rename/Delete mail folder - Create vfolder from message sender/message subject - Creating an user account Following are the requirements for setting up LDTP + Python 2.3 or higher + Python Imaging Library + libstatgrab and pystatgrab [please use the development snapshot for libstatgrab which includes an important fix for a crasher bug].

ANNOUNCE: Rx4RDF and Rhizome 0.5.1
by Adam Souzis 26 Oct '05

26 Oct '05

Rx4RDF is application stack for building RDF-based applications and web sites implemented in Python. Rhizome is a Wiki-like content management and delivery system built on Rx4RDF that brings the Wiki approach to building dynamic web sites. What's new? Major changes since last announced release (0.4.3): * RxPath's RDF mapping has been applied to Schematron, enabling a Schematron schema to be used to validate a RDF model. * The Raccoon application server has been signficantly restructured, new features include: - applications can now use XML (in addition to RDF) data stores. - added SQL-like triggers for changes to the data store. - added a two-phase commit transaction coordinator. - enable multiple applications to run in one Raccoon process, each owning part of the URL namespace. * Rhizome enhancements include: - Sports a new look and feel provided by a new, more usable and polished default theme. - The authorization schema has been made considerably more flexible and expressive, enabling all changes to the RDF data store to now be authorized. - In addition, all changes to the data store are now incrementally validated by a Schematron schema. In addition, there have several other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt for more details. More Info: * Rx4RDF is a set of technologies designed to make RDF more accessible and easier to use. It includes: ** RxPath provides a deterministic mapping between the RDF abstract syntax to the XPath data model, allowing you to query, transform, update and validate a RDF model with languages syntactically indentical to XPath, XSL, XUpdate and Schematron. ** ZML is a Wiki-like text formatting language that lets you write arbitrary XML or HTML (using Python-esque indentation rules), enabling you to author XML documents with (nearly) the same ease as a Wiki entry. ** RxML is an alternative XML serialization for RDF that is designed for easy authoring in ZML, allowing novices to author and edit RDF metadata. * Raccoon is a simple application server that uses an RDF model for its data store, roughly analogous to RDF as Apache Cocoon is to XML. Raccoon uses RxPath to translate arbitrary requests (currently HTTP, XML-RPC and command line arguments) to RDF resources, each of which can be associated with RxSLT and RxUpdate stylesheets. * Rhizome is a Wiki-like content management and delivery system built on Raccoon that takes the concept of the Wiki to the next level: everything is editable, not just content but its meta-data and behavior, even the structure of the site itself. Furthermore, Wiki entries are abstract globally unique RDF resources that can have any kind of content and whose presentation is contextual.
