ANN: PyEnchant 1.2.0
by Ryan Kelly 19 Sep '07

19 Sep '07

Hi All, I'm pleased to announce the release of PyEnchant version 1.2.0. This version includes some important updates in the underlying enchant library, and implements basic "filters" to allow skipping of email addresses, WikiWords, URLs, etc during a spellchecking session. Cheers, Ryan About: ------ Enchant (http://www.abisource.com/enchant/) is the spellchecking package behind the AbiWord word processor, is being considered for inclusion in the KDE office suite, and is proposed as a FreeDesktop.org standard. It's completely cross-platform because it wraps the native spellchecking engine to provide a uniform interface. PyEnchant brings this simple, powerful and flexible spellchecking engine to Python: http://pyenchant.sourceforge.net/ It also provides extended functionality including classes for tokenizing text and iterating over the spelling errors in it, as well as a ready-to-use text interface and wxPython dialog. Current Version: 1.2.0 Licence: LGPL with exemptions, as per Enchant itself ChangeLog for 1.2.0: -------------------- * Implemented "filters" that allow tokenization to skip common word forms such as URLs, WikiWords, email addresses etc. * Now ships with enchant-1.3.0, meaning: * PWLs can return a useful list of suggestions rather than the empty list * Hunspell replaces MySpell as the default Windows backend * Tokenization doesnt split words at non-alpha characters by default * GtkSpellCheckerDialog contributed by Fredrik Corneliusson * Removed deprecated functionality: * Dict.add_to_personal * All registry handling functionality from enchant.utils * enchant.utils.SpellChecker (use enchant.checker.SpellChecker) * Removed PyPWL, as native enchant PWLs can now suggest corrections -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.

Creating Web 2.0 sites using Python2.5, without a database.
by George Belotsky 31 Jan '07

31 Jan '07

LinuxWorld has published my article about the Relative Static approach to web application design ("BoSStats, FlightFeather and the Relative Static Web"). http://www.linuxworld.com/news/2007/012907-flightfeather.html This method tries to capture as much system state as possible in static HTML files, which the webserver can use directly. While the resulting site is dynamic, it is static from the webserver's point of view. I use this approach in my FlightFeather and Flightdeck-UI Online Free/Open Source projects. The article describes why Python (specifically version 2.5) is such a good choice for Relative Static web applications. The discussion focuses on the newly introduced "with" statement and the context manager type (see link to page 5, below). http://www.linuxworld.com/news/2007/012907-flightfeather.html?page=5

FlightFeather Social Networking Platform 0.3.2
by George Belotsky 31 Jan '07

31 Jan '07

FlightFeather's goal is "social networking for everyone". This means that *anyone* should have a chance to run a *popular* social networking site -- on minimal hardware, and without wasting bandwidth. Release 0.3.2 is the current development release. It updates the submission feature (which currently supports Digg) introduced in version 0.3.0. The old behavior was to submit article body text only up to the first URL in the story. The new approach submits the maximum allowed text, including any URLs encountered along the way. In the future, there may be an option to enable the old behavior, as well as other, alternative ways to process submissions. The current beta release of FlightFeather is 0.2.8. You can download these releases (free/open source under the GPL) from the "BoSStats" site, which runs on FlightFeather. http://www.bosstats.com/flightfeather.html You are always welcome to participate in the discussion on the "BoSStats" site; the topic covered (what makes a good boss, office politics, etc.) is valuable in and of itself. Please, however, refrain from posting test comments, as the site is live. A Brief Overview of FlightFeather and BoSStats ---------------------------------------------- FlightFeather is in its early stages, but it is functional. You can see the system in action on the BoSStats site. BoSStats is dedicated to improving the world of work: you can discuss what makes a good boss, or share your experiences of office politics. You can also comment and vote on the posts made by others. The application does not set cookies, and no registration is required for anything except voting. http://www.bosstats.com/ BoSStats is a good testbed for FlightFeather, and has value of its own, since meaningful advice about work-related problems is very hard to find. A "Wisdom of Crowds" solution -- particularly with strong privacy protection (see below) -- is a necessary addition to this field. FlightFeather's most important feature is that all write requests generate (or modify) HTML files. In consequence, a pure read (the most common operation) merely serves static pages. The major design focus for FlightFeather are responsiveness and performance; the system should eventually support very high traffic volumes. In addition, FlightFeather allows for a great deal of user privacy -- a critical, rapidly emerging problem in the social networking realm.

ANN: Release of SimPy 1.8
by Klaus Muller 31 Jan '07

31 Jan '07

With great pleasure we announce the availability of SimPy version 1.8 This is a major release, with significant changes to API and documentation and with a number of bug fixes. What is SimPy? ============== SimPy (= Simulation in Python) is an object-oriented, process-based discrete-event simulation language completely implemented in Python. It is released under the GNU Lesser GPL (LGPL). SimPy provides the modeler with components of a simulation model including processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics. Random variates are provided by the standard Python random module. Many users claim that SimPy is one of the cleanest, easiest to use discrete event simulation packages! SimPy is in use at many universities, research institutes and in industry. SimPy comes with data collection capabilities, GUI and plotting packages. It can be easily interfaced to other packages, such as plotting, statistics, or database systems. ============================= Release notes for SimPy 1.8 ============================= This version is the result of many months of intense collaboration in the SimPy community. It includes design ideas and improvements proposed by Steve Rogers, Matt Kuperholz and Igor Cananea. It also includes code in SimulationRT contributed by Robert C. Ramsdell III which allows setting of the simulation to real time ratio during a simulation run. Many thanks to all contributors! Our apologies if we have forgotten to mention a contributor! For the first time, we had an editor/co-author (Bob Helmbold) working with us on rewriting Manual and Cheatsheet. You will like the resulting documents! Important Note: =============== SimPy 1.8 and future releases will not run under the (obsolete) Python 2.2 version. Additions ========= - New compound yield statements support time-out or event-based reneging in 'get' and 'put' operations on Store and Level instances. - 'yield get' on a Store instance can now have a filter function which selects which and how many items (e.g. "3 parcels weighing less than 3 pounds") should be retrieved. - All Monitor and Tally instances are automatically registered in lists 'allMonitors' or 'allTallies', respectively. - The new function 'startCollection' allows activation of Monitors and Tallies at a specified time (e.g. after a warm up period). - A 'printHistogram' method was added to Tally and Monitor which generates a nicely formatted table-form histogram. - In SimPy.SimulationRT: A function to allow changing the ratio of wall clock to simulation time has been added. It facilitates slowing down or speeding up model execution, e.g. for interactive models or games. Changes to code and documentation ================================= - The Manual has been thoroughly edited, restructured and rewritten with a view to greater clarity and readability. It is provided in both HTML and PDF format. - The Cheatsheet has been rewritten in a tabular format and reduced to just a few pages. The goal was to turn it into a concise desktop reference of SimPy commands. The Cheatsheet is provided in both XLS (MS Excel spreadsheet) and PDF format. - The obsolete Interfacing document has been replaced by a brief introduction to using the matplotlib library for publication-quality plotting of SimPy-produced data. - The version of SimPy.Simulation(RT/Trace/Step) is now accessible by the variable 'version'. - The '__str__' method of Histogram was changed to return a table format (like that produced by the new 'printHistogram' method of Monitor and Tally). Repairs ======= - Repaired a bug in 'yield waituntil' runtime code. - Introduced check for '<capacity' parameter of a Level or a Store being a number > 0. - Added code so that 'self.eventsFired' gets set correctly after an event fires in a compound yield get/put with a waitevent clause (reneging case). - Repaired a bug in prettyprinting of Store objects (the buffer content, i.e. '._theBuffer' was not shown) by changing '._theBuffer' to '.theBuffer'. ------------------------------------------------------------------------ (end of Release Notes) Enjoy! Best wishes for happy, productive SimPying in 2007! Klaus Muller TonyVignaux Bob Helmbold

New mailing list: centralOH@python.org
by Catherine Devlin 30 Jan '07

30 Jan '07

There's a new mailing list, centralOH(a)python.org, for Python users in central Ohio (outside the range of the Cleveland Python Interest Group). http://mail.python.org/mailman/listinfo/centraloh The hope is that, once several Pythonistas are on the list, we can use it to plot and scheme (no, not Scheme) toward building a real user group with live activities. The mailing list will be used to make plans for it. Please pass this notice on to any Ohio Pythonistas you may know who are near Columbus, Dayton, etc. Thanks so much! -- - Catherine http://catherinedevlin.blogspot.com/
