[ANN] Voidspace Pythonutils Updates
by Fuzzyman 08 Apr '05

08 Apr '05

Lots of updates to the Voidspace modules and recipes. Update to the Firedrop plugins see : http://www.voidspace.org.uk/python/programs.shtml#firedrop New version of FireSpell the spell checker (based on PyEnchant by Ryan Kelly) New plugin called FireMail which lets you send blog entries (or articles) by email - either as HTML or text. All the plugins are available for download. There is also docs on installing and using the plugins and docs on writing plugins. downman.py http://www.voidspace.org.uk/python/cgi.shtml#downman More improvements to downman.py - the simple download manager CGI 2005/03/15 Version 0.4.0 Configuration moved into external config file. HTML stuff mmoved into downman_templates.py Put quotes round filename (This stops firefox truncating filenames with spaces) Flush the output buffer as we serve the file (may help those who have to use env in the shebang line) guestbook.py http://www.voidspace.org.uk/python/guestbook.html Quite a big change - with a cleaning up of the default HTML templates and several new features to help combat guestbook spam. 2005/04/06 Version 1.3.0 Lots of restyling in the HTML templates - not *quite* so horrible now. We write new entries at the start of the file rather than the end (undoes a bug introduced in 1.2.0) Max of two URLs in an entry. A few extra words added to the banned list. (Still trying to combat guestbook spam) New value 'BREAKVAL' added to templates (so we can use the XHTML <br /> if needed) The '_charset_' field added to the form and value checked (in case page encoding changed by guests browser) Now use rel="nofollow" in links to foil spammers Email addresses shown using javascript in an attempt to foil address harvesters. Obviously invalid email addresses and urls are removed. (very basic) Jalopy and Login Tools Not a huge amount of progress - but a few bugs fixed. http://www.voidspace.org.uk/python/jalopy.html http://www.voidspace.org.uk/python/logintools.html 2005/03/23 Admin levels are now preserved when new users are created or invited. Corrected bug causing accounts to not be editable. Changed all the shebang lines to '#! /usr/bin/python' Updated to latest versions of all the pythonutils modules (like ConfigObj) Fixed typo in HTML for editing users (causing crashes). cgiutils.py http://www.voidspace.org.uk/python/recipebook.shtml#utils cgitutils now has much better functions for handling emails. It includes a function for creating HTML emails and a single function will do the sending, rather than 3 functions for the three different cases as before (using sendmail, using smtplib, using smtplib with login). 2005/04/07 Version 0.3.0 Changed the email functions, this may break things (but it's better this way) Added createhtmlemail, removed loginmailme mailme is now a wrapper for sendmailme, mailme, *and* the old loginmailme upload.py http://www.voidspace.org.uk/python/cgi.shtml#upload 2005/04/07 Version 1.1.1 We now set I/O to binary mode for windows. googleCacheServer.py http://www.voidspace.org.uk/python/recipebook.shtml#google An innovative use of the google api ! Version 0.1.3 5th April 2005 This is a simple implementation of a proxy server that fetches web pages from the google cache. It's based on SimpleHTTPServer and lets you explore the internet from your browser, using the google cache. See the world how google sees it. Alternatively - retro internet - no CSS, no javascript, no images, this is back to the days of MOSAIC ! Best Regards, Fuzzy http://www.voidspace.org.uk/python

Febrl-0.3 released
by Peter Christen 07 Apr '05

07 Apr '05

Canberra, 7 April 2005 The ANU Data Mining Group is pleased to announce the release of Febrl 0.3, a prototype open source record linkage, deduplication and geocoding system intended to make probabilistic record linkage easier, faster and more accurate for biomedical and other researchers. The programs, known collectively as "Febrl" - Freely Extensible Biomedical Record Linkage - address the data cleaning and standardisation tasks which are essential first steps for most record linkage projects, and provide routines for probabilistic record linkage and record deduplication, as well as geocode matching based on the Australian G-NAF (Geocoded National Address File, www.g-naf.com.au) database. This fifth release Febrl Version 0.3 has been updated to Python 2.4 (also runs on Python 2.3). We would like to thank everybody who sent us bug-reports or other comments. The main features of the current release are: * Probabilistic and rules-based cleaning and standardisation routines for names, addresses, dates and telephone numbers. * A geocoding matching system based on the Australian G-NAF (Geocoded National Address File) database. * A variety of supplied look-up and frequency tables for names and addresses. * Various comparison functions for names, addresses, dates and localities, including approximate string comparisons, phonetic encodings, geographical distance comparisons, and time and age comparisons. Two new approximate string comparison methods (bag distance and compression based) have been added in this release. * Several blocking (indexing) methods, including the traditional compound key blocking used in many record linkage programs. * Probabilistic record linkage routines based on the classical Fellegi and Sunter approach, as well as a 'flexible classifier' that allows a flexible definition of the weight calculation. * Process indicators that give estimations of remaining processing times. * Access methods for fixed format and comma-separated value (CSV) text files, as well as SQL databases (MySQL and new PostgreSQL). * Efficient temporary direct random access data set based on the Berkeley database library. * Possibility to save linkage and deduplication results into a comma-separated value (CSV) text file (new). * One-to-one assignment procedure for linked record pairs based on the 'Auction' algorithm. * Supports parallelism for higher performance on parallel plat- forms, based on MPI (Message Passing Interface), a standard for parallel programming, and Pypar, an efficient and easy-to-use module that allows Python programs to run in parallel on multiple processors and communicate using MPI. * A data set generator which allows the creation of data sets of randomly generated records (containing names, addresses, dates, and phone and identifier numbers), with the possibility to include duplicate records with randomly introduced modifications. This allows for easy testing and evaluation of linkage (deduplication) processes. * Example project modules and example data sets allowing simple running of Febrl projects without any modifications needed. - An extensive 185 page manual. Febrl, which is written in the free open source Python programming language, is itself available under a free, open source license, which we hope will encourage others to contribute to its further development and support. Contact details, background information, documentation and, of course, the program code are all available from the project Web site at http://datamining.anu.edu.au/linkage.html as well as from 'sourceforge.net' at http://sourceforge.net/projects/febrl We would like to stress that the programs are still in the early stages of development, and we do not yet recommend them for production use, but we encourage you to try them and to provide us with feedback. We particularly welcome bug reports and ideas for future development. There are many ways to help with the project: testing, programming and software engineering, documentation and technical writing, translation, provision of (anonymous, non-confidential) training and example data sets, and testing.

[Announce] SpamBayes 1.1a1 is now available
by Tony Meyer 07 Apr '05

07 Apr '05

The SpamBayes team is pleased to announce release 1.1a1 of SpamBayes. As is now usual, this is both a release of the source code and of an installation program for all Microsoft Windows users. This is an *ALPHA* release. It should only be installed by users willing to try out experimental software, and almost certainly contains new bugs. If you don't know what an alpha release is, please stick with 1.0.4 for the moment. The 1.1 release has been worked on since May of 2004, so contains a vast number of improvements over the 1.0.x line. These include, but are not limited to: * New database backends, including ZODB and ZOE. * Internationalisation support, including partial translations into French and Spanish. * Improved statistics reporting. * The ability to set audio notifications with the Outlook plug-in. * The ability to set the Outlook plug-in to move/copy ham, as well as spam/unsures. * Partial POP3 over SSL support for sb_server. * A vastly improved sb_imapfilter. Suggestions about what to try out can be found here: http://entrian.com/sbwiki/TryOutThePreRelease This release, like the ill-fated 1.0.2 and 1.0.3, is built with Python 2.4. We believe that the remaining incompatibilities with Python 2.4 have been resolved, and so this release should also include superior email parsing to the 1.0.x line. Details about the changes in this release can be found at http://sourceforge.net/project/shownotes.php?release_id=318577 You can get the release via the 'Download' page at http://spambayes.org/download.html Enjoy the new release and your spam-free mailbox :-) As always, thanks to everyone involved in this release! Tony. (on behalf of the SpamBayes team) --- What is SpamBayes? --- The SpamBayes project is working on developing a Bayesian (of sorts) anti-spam filter (in Python), initially based on the work of Paul Graham, but since modified with ideas from Robinson, Peters, et al. The project includes a number of different applications, all using the same core code, ranging from a plug-in for Microsoft Outlook, to a POP3 proxy, to various command-line tools. The Windows installation program will install either the Outlook add-in (for Microsoft Outlook users), the SpamBayes server program (for all other POP3 mail client users, including Microsoft Outlook Express), or the SpamBayes IMAP filter (for all IMAP mail client users). All Windows users (including existing users of the Outlook add-in) are encouraged to use the installation program. If you wish to use the source-code version, you will also need to install Python - see README.txt in the source tree for more information.

Sybase module 0.37 released
by Dave Cole 06 Apr '05

06 Apr '05

WHAT IS IT: The Sybase module provides a Python interface to the Sybase relational database system. It supports all of the Python Database API, version 2.0 with extensions. NOTES: The 0.37 release is identical to 0.37pre3 as no problems were reported with the prerelease. This release contains a number of small bugfixes and patches received from users. I have been unable to find the source of the memory leak reported here: http://www.object-craft.com.au/pipermail/python-sybase/2004-December/000346… The test program I wrote follows: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - import sys import Sybase db = Sybase.connect(..., auto_commit=True) db.execute(''' if exists (select name from sysobjects where name = "sp_test_leak") begin drop procedure sp_test_leak end ''') db.execute(''' create procedure sp_test_leak @arg int as select @arg ''') for i in range(200): for j in range(1000): c = db.cursor() c.callproc('sp_test_leak', {'@arg': 12345 }) sys.stdout.write('%3d\r' % i) sys.stdout.flush() sys.stdout.write('\n') - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - If someone is able to modify this and come up with a leaking result I am interested in working on the fix. You can build for FreeTDS like this: python setup.py build_ext -D HAVE_FREETDS -U WANT_BULKCOPY python setup.py install The module is available here: http://www.object-craft.com.au/projects/sybase/download/sybase-0.37pre3.tar… The module home page is here: http://www.object-craft.com.au/projects/sybase/ CHANGES SINCE 0.36: * Fix FreeTDS compilation and rearrange header includes to remove warnings. * Cursor state initialisation fix from Skip Montanaro. * Callback declaration fix on Windows from Vadim Beloborodov. * Cursor output parameters now work when parameters are passed as a sequence. * Output parameters now work for FreeTDS 0.62.4. 1> create procedure sp_test_output 2> @num int, @result int output 3> as 4> select @result = @num 5> go params = c.callproc('sp_test_output', {'@num': 12345, '@result': Sybase.OUTPUT(1)}) print params['@result'] * The CS_STATUS_RESULT result set is now consumed internally in the Cursor and does not appear in the result sets consumed by the fetch and nextset methods. The return value from the stored procedure is available in the .return_status member of the Cursor. It will only contain a meaningful value once all of the row result sets have been consumed. Note that this does not work with FreeTDS 0.62.4. The return_status seems to always be 0. Research shows that the problem is probably in the CT emulation layer as tsql displays the correct value, but sqsh displays 0. * Output hook patch from Ty Sarna has been applied. * Applied patch from Andre Sedinin to improve error handling. * Improved detection of SYBASE_OCS. -- http://www.object-craft.com.au

Portland area Code Sprint on April 9-10
by Arlo 04 Apr '05

04 Apr '05

XP / PYTHON CODE SPRINT XPDX will be hosting a code sprint on April 9-10, 2005 in downtown Portland, Oregon. We're all meeting in one big room, where we'll code and talk smack until beer-thirty. Come pair with long-time XPers to learn their techniques while working on nifty Python projects. If you're intending to attend at least part of the sprint, please email Arlo Belshee (a_xp_code_sprint(a)arlim.org). You can also add your name to the Sprint wiki, at http://c2.com/cgi/wiki?XpCodeSprint . We've currently got about 20 confirmed attendees from Oregon, Washington, and California. There's no headcount limit; come on down and join us for a weekend of coding, learning, and fun. If you can't make it for the whole weekend, just tell Arlo which day you can make it for. Many of the attendees are new to Python. Some are experts. So feel welcome regardless of your skill level. Also, Python integrates well with other common languages, allowing us to easily blend in work in a number of different areas. There will probably be projects in a number of different languages, such as: * Pure Python * Python and C++, via boost.org's boost::python interoperability template library * Python and Java, via Jython * And probably some Smalltalk, just because This is not a pure XP Sprint. Please feel free to come if you've never even heard of the practice. Many of us will be learning it this weekend. Also, if you have no interest in XP, come anyway. There will be a lot of Python coding and a variety of interesting topics. ------------------------------------------------------------------------ There are several potential projects for you to work on. If any of these catch your eye, come to the sprint ready to plow into it. If they don't, come on down with your own pet project - or even with no project at all. Someone'll grab you as a pair partner. http://pythoncard.sourceforge.net/ http://moinmoin.wikiwikiweb.de/, or MoinMoin plugins. http://scons.sourceforge.net/ http://ipodder.sourceforge.net/index.php Agile programming infrastructure. Some (as yet poorly defined) set of integrated tools to allow unit testing, automated build, automated smoke testing, release control, SCM, and other necessary activities. How about a rocket telemetry data analysis or visualization tool for http://psas.pdx.edu/? We could even provide live hardware. Scope, a simpler automated test framework for C++ that takes advantage of the features of that language. --------------------------------------------------------------------------- LOCATION AND LOGISTICS Critical Path Software his kindly invited us to use a floor of its downtown facilities for this sprint. The office is at 711 SW Alder St. in downtown Portland. It is about a block from Pioneer Courthouse Square, so is an easy MAX ride from many places in the city. The code sprint will run on April 9th and 10th. We will start each day at 10:00, and run until evening. Saturday night, several of us will probably troop on down to one of the local beer establishments. Arlo Belshee is organizing this event. If you have questions, you may contact him via email at a_xp_code_sprint(a)arlim.org. Arlo
