[ANN] PyDO-2.0b1 Released
by Jacob Smullyan July 26, 2005

July 26, 2005

I'm pleased to announce the release of PyDO-2.0b1, the second beta release of the 2.0 series. What's New ---------- * more tests and corresponding bug fixes. What it is ---------- PyDO is Drew Csillag's ORM (Object-Relational Mapper) database access library for Python that facilitates writing a Python database access layer. PyDO attempts to be simple, flexible, extensible, and unconstraining. PyDO 2 is a rewrite of the 1.x series distributed with SkunkWeb. It has several enhancements: * PyDO can now be used in multi-threaded or twisted-style asynchronous sitations, with or without a customizable connection pool. * PyDO objects are now dict subclasses, but also support attribute access to fields. * Projections -- subsets of the field list of a super-class -- are now supported by the PyDO.project() method. * Table attributes are now declared in a more concise way. * PyDO2 supports runtime table introspection. * Overall, the API has been tightened and the code restructured. PyDO 2 requires Python 2.4 or later. It currently supports PostgreSQL, MySQL, Sqlite, MSSQL, and Oracle, and support for other databases is planned. PyDO is dual GPL/BSD licensed. The source tarball is available at SkunkWeb's berlios site: https://developer.berlios.de/projects/skunkweb/ or, more directly: http://download.berlios.de/skunkweb/PyDO-2.0b1.tar.gz Questions pertaining to PyDO can be addressed to the SkunkWeb mailing list at sourceforge: http://lists.sourceforge.net/lists/listinfo/skunkweb-list Cheers, js -- Jacob Smullyan

pyparsing 1.3.2 released
by Paul McGuire July 25, 2005

July 25, 2005

"The best laid plans o' mice an' men / Gang aft a-gley" So said Robert Burns (who really should do something about that speech impediment!). And so said I about 6 weeks ago, when I thought that I would leave pyparsing alone for awhile, after the 1.3.1 release. Well, here we are, and I'm announcing the 1.3.2 release, with some changes that I'd like to get released quickly. Here is the excerpt from the change log: Version 1.3.2 - July 24, 2005 ----------------------------- - Added Each class as an enhanced version of And. 'Each' requires that all given expressions be present, but may occur in any order. Special handling is provided to group ZeroOrMore and OneOrMore elements that occur out-of-order in the input string. You can also construct 'Each' objects by joining expressions with the '&' operator. When using the Each class, results names are strongly recommended for accessing the matched tokens. (Suggested by Pradam Amini - thanks, Pradam!) - Stricter interpretation of 'max' qualifier on Word elements. If the 'max' attribute is specified, matching will fail if an input field contains more than 'max' consecutive body characters. For example, previously, Word(nums,max=3) would match the first three characters of '0123456', returning '012' and continuing parsing at '3'. Now, when constructed using the max attribute, Word will raise an exception with this string. - Cleaner handling of nested dictionaries returned by Dict. No longer necessary to dereference sub-dictionaries as element [0] of their parents. === NOTE: THIS CHANGE MAY BREAK SOME EXISTING CODE, BUT ONLY IF PARSING NESTED DICTIONARIES USING THE LITTLE-USED DICT CLASS === (Prompted by discussion thread on the Python Tutor list, with contributions from Danny Yoo, Kent Johnson, and original post by Liam Clarke - thanks all!) Download pyparsing at http://pyparsing.sourceforge.net. -- Paul ======================================== Pyparsing is a pure-Python class library for quickly developing recursive-descent parsers. Parser grammars are assembled directly in the calling Python code, using classes such as Literal, Word, OneOrMore, Optional, etc., combined with operators '+', '|', and '^' for And, MatchFirst, and Or. No separate code-generation or external files are required. Pyparsing can be used in many cases in place of regular expressions, with shorter learning curve and greater readability and maintainability. Pyparsing comes with a number of parsing examples, including: - "Hello, World!" - chemical formulas - configuration file parser - web page URL extractor - 5-function arithmetic expression parser - subset of CORBA IDL - chess portable game notation - simple SQL parser - Mozilla calendar file parser - EBNF parser/compiler

ANN: MyNewspaper 1.2
by Iñigo Serna July 24, 2005

July 24, 2005

Hi there, I'm really pleased to announce the second public release of MyNewspaper. MyNewspaper v1.2: "faster (25-35%), cleaner (100%), smaller(69%) and even more robust(100%)". If you liked the first version but thought... uhmm it's buggy and slow, then this is your release. In fact first version was a proof of concept to get some attention and feedback. What is MyNewspaper after all? ============================== MyNewspaper is a personal RSS Aggregator and Reader, licensed under GPL. Why? As everybody says, I couldn't find any which fulfills all my requirements. In fact I used liferea and was pretty happy with it, but it eats lot of memory when you have many feeds and the program is running for much time, but the main problem was that it's a desktop program and I couldn't read the feeds from the work. So I started writing my own RSS aggregator and reader. MyNewspaper is written in Python with a bit of javascript and uses sqlite as permanent storage for the articles. From v1.2 up sqlobject is used as an abstraction layer for database access, so it would be very easy to support other database engines. It is installed as a CGI, so in order to use and manage it you need a web browser and a web server. Feeds are updated by a command run by cron or from the WebUI. Changes ======= v1.2: "faster (25-35%), cleaner (100%), smaller(69%) and even more robust(100%)" * a major rewrite and clean up of the whole code * uses sqlobject as database abstraction layer * uses Cheetah Template as html template * generated html is valid now * bugs fixing IMPORTANT NOTE to upgrade from v1.0: * download and install sqlobject and Cheetah Template * copy all the needed files to the directory overwriting old ones * you need to upgrade db: $ cd /path_to/mynewspaper $ ./migrate_db.py Home page and download ====================== Read more and download it from: http://inigo.katxi.org/devel/mynewspaper or http://www.terra.es/personal7/inigoserna/mynewspaper Of course, all comments, suggestions etc. are welcome. And yes, I know code is really awful now, but I wanted to make a public release to get some feedback while improving the code. Best regards, -- Iñigo Serna <inigoserna(a)terra.es> Katxijasotzaileak

[ANN] Fail2Ban 0.5.1
by Cyril Jaquier July 23, 2005

July 23, 2005

Hi, The version 0.5.1 of Fail2Ban is available. "Fail2Ban is written in Python. It scans log files like /var/log/pwdfail or /var/log/apache/error_log and bans IP that makes too many password failures. It updates firewall rules to reject the IP address." This release fixes bugs discovered in 0.5.0 and add multi targets for the log output including syslog. Default config creates an iptables chain for each section. Please do not forget to remove your previous 0.4.x version before upgrading to 0.5.x and update your configuration file. fail2ban-0.5.1 is still an unstable version but should work perfectly. Homepage: http://fail2ban.sourceforge.net Best Regards, Cyril Jaquier

mma - Musical MIDI Accompaniment: Beta 0.15
by Bob van der Poel July 22, 2005

July 22, 2005

I'm pleased to announce the release of my program mma - Musical MIDI Accompaniment version: Beta 0.15 MMA is a accompaniment generator -- it creates midi tracks for a soloist to perform with. User supplied files contain pattern selections, chords, and MMA directives. MMA is very versatile and generates excellent tracks. It comes with an extensive user-extendable library with a variety of patterns for various popular rhythms, an extensive user manual, and many demo songs. MMA is a command line driven program. It creates MIDI files which need a sequencer or MIDI file play program. MMA is written in Python. You'll need Python 2.3 (or later) for MMA to function. MMA is supplied in 4 tar.gz archives. Included: mma-bin -- the main script and library files. mma-html -- documentation in HTML format. mma-pdf -- documentation in PDF format. mma-songs -- a collection of about 230 songs in MMA format. If you get all four download packages the total size is still less than 1.5 megabytes. MMA is currently in final BETAs. We are hoping for a 1.0 release in summer 2005. Right now we need help in debugging the program, creating songs for distribution, and new and improved library files. Best of all, MMA is free. It is released under the terms of the GNU General Public License. It has been developed on a Linux platform, but should be usable on just about any system. A detailed page now exists on our web site on how-to install on a Windows system. MMA is available on my personal home page: http://mypage.uniserve.com/~bvdp/mma/ If you have any questions or comments, please send them to: bvdp(a)uniserve.com Beta 0.15: A number of synth translation options have been added, chord voicings improved, more chord adjustment options, and a lot of minor (and not-so-minor) bug fixes. Comments appreciated! -- Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bvdp(a)uniserve.com WWW: http://mypage.uniserve.com/~bvdp
