ANN: TakeNote 0.4.1 - Note taking and organization
by rasmus Aug. 11, 2008

Aug. 11, 2008

This release contains - several bug fixes - better support for HTML and image copy and paste - customizable word-wrap TakeNote is a simple cross-platform note taking program implemented in Python. I have been using it for my research and class notes, but it should be applicable to many note taking situations. Although this is my first release, it has most of the basic features needed for effective notes. TakeNote is ideal for storing your class notes, TODO lists, research notes, journal entries, paper outlines, etc in a simple notebook hierarchy with rich-text formatting, images, and more. Using full-text search, you can retrieve any note for later reference. TakeNote is designed to be cross-platform (runs on Windows, Linux, and MacOS X, implemented in Python and PyGTK) and stores your notes in simple and easy to manipulate file formats (HTML and XML). Archiving and transferring your notes is as easy as zipping or copying a folder. TakeNote is licensed under GPL. TakeNote 0.4.1 is has the following features: * Rich-text formatting * Hierarchical organization for notes * Full-text search * Inline images * Integrated screenshot * Spell checking (via gtkspell) * Auto-saving * Built-in backup and restore (archive to zip files) * Cross-platform (Linux, Windows, MacOS X) Web site and download: http://rasm.ods.org/takenote Matt Rasmussen

Simulator of arbitrary fixed and infinite precision binary floating point
by Rob Clewley Aug. 11, 2008

Aug. 11, 2008

Dear list, I have written a module to simulate the machine representation of binary floating point numbers and their arithmetic. Values can be of arbitrary fixed precision or infinite precision, along the same lines as python's in-built decimal class. The code can be found here: http://www2.gsu.edu/~matrhc/binary.html The design is loosely based on that decimal module, and the primary intended use of this module is educational. You can play with different IEEE 754 representations with different precisions and rounding modes, and compare with infinite precision Binary numbers. For instance, it is easy to explore machine epsilon, representation/rounding error using a much simpler format such as a 4-bit exponent and 6-bit mantissa. The usual arithmetic operations are permitted on these objects, as well as representations of their values in decimal or binary form. Default contexts for half, single, double, and quadruple IEEE 754 precision floats are provided. Binary integer classes are also provided, and some other utility functions for converting between decimal and binary string representations. The module is compatible with the numpy float classes and requires numpy to be installed. The source code is released under the BSD license, but I am amenable to other licensing ideas if there is interest in adapting the code for some other purpose. Full details of the functionality and known issues are in the module's docstring, and many examples of usage are in the accompanying file test_binary.py (which also acts to validate the common representations against the built-in floating point types). I look forward to hearing feedback, especially in case of bugs or suggestions for improvements. -Rob -- Robert H. Clewley, Ph. D.

The Python Replybot 5.0.0a3
by Barry Warsaw Aug. 8, 2008

Aug. 8, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm happy to announce the release of my newly updated Python Replybot program. This is an alpha release, but I am using it in production. Hopefully you'll take a look and let me me know what you think. The Python Replybot sends automatic responses to email messages, under the appropriate circumstances. It strives to be RFC and de-facto standards compliant, so that it will never send auto-responses to Precedence bulk|junk|list messages, any mailing list message that support the RFC 2369 List-ID header, any null Return-Path message, etc. It supports whitelists and configurable grace periods. It allows you to segregate responses into 'contexts' so that you can have multiple addresses each with their own grace period. It supports downloading the response messages via any url, with a configurable cache lifetime, and it supports purging of whitelists, reply records, and the cache. The Python Replybot 5.0.0a3 requires Python 2.5, SQLite, and Storm, but the setup.py does all the work for you. You can download the package from the Cheeseshop: http://pypi.python.org/pypi/replybot/ or use easy_install: % sudo easy_install replybot The project's source code is managed under Bazaar and hosted on Launchpad: https://launchpad.net/replybot Please use the Launchpad bug tracker to report any problems. Enjoy! - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQCVAwUBSJypfXEjvBPtnXfVAQLkqAP/Q9kNxKGSu39VEhMoXf/goR22NU9XISXt QcWTxHTFjAIeoA5WGD2qSBA2vMLngOSoqKIjdAr8pdeBK/lE8mR4V2UHSbQ1jDLZ nNj58TiKPhsGbZqiD+Bv9KeGQs6/dkJFdUJuZVE4HQb24Q/9gR/R/Ly3FrzzBtns 4/Foexg5DYo= =JP7q -----END PGP SIGNATURE-----

IronPython 1.1.2
by Dave Fugate Aug. 8, 2008

Aug. 8, 2008

Hello Python Community, I'm pleased to announce the release of IronPython 1.1.2 which is our last planned 1.1 release. Our 1.x releases in turn target compatibility with CPython 2.4. IronPython v1.1.2 is a minor update in which we fixed the most requested CodePlex bugs and also a handful of trivial bugs. In total twenty-one bugs have been resolved for 1.1.2. It's worth noting that this included the implementation of the "_winreg" CPython module and a few performance improvements in targeted areas. Please also note that there are two potentially breaking changes in this release: [PicExportError] * nt.unlink will now throw an exception if the file doesn't exist, as it does in CPython [PicExportError] * The signature of IronPython.Runtime.Operations.Ops.Id() has changed and it now returns an object instead of long. This maps to the id() function in Python. Note that there is no change for Python caused by this and only code which is directly calling Ops.Id from a statically typed language like C# or VB will be affected. The following CodePlex Work Items were closed: * 16368 1.1.2: nt.access is missing * 16402 1.1.2: implement _winreg module * 15105 1.1.2: endpos is zero in IronPython 1.1.1 * 16335 1.1.2: Event handlers can cause circular references and leak memory * 16337 1.1.2: Trivial: Implement float.__lt__(float) * 16338 1.1.2: Using lambda in class definition will add <lambda$..> into the * 16342 1.1.2: calling base class __call__ invokes constructor instead * 16343 1.1.2: problem with __slots__ and __init__ in new-style classes * 16347 1.1.2: Trivial: popen shouldn't open new window * 16348 1.1.2: Removes the inexistent file did not throw OSError in IP * 16350 1.1.2: int() doesn't convert representable longs to int * 16351 1.1.2: dict.update doesn't take keyword arguments - differs from CPython * 16353 1.1.2: Trivial: int('0x20', 16) fails to parse, long too * 16355 1.1.2: unpacking single element tuples in for-statement, listcomp and generator * 16356 1.1.2: socket.getnameinfo(...) broken under Vista * 16360 1.1.2: Class with slots and getattr not compatible * 16363 1.1.2: Can't call method w/ nullable as 1st argument w/ greater than 5 arguments * 16364 1.1.2: Backport fix for compiled regular expressions * 16365 1.1.2: Tuple hashing improvements * 16366 1.1.2: PyCF_DONT_IMPLY_DEDENT support in compile * 16749 1.1.2 (Trivial): Modifier of PythonEngine.DefaultCompilerContext(..) We'd like to thank everyone in the community who contributed to these bugs: Ronnie Maor, jackeyoo, sanxiyn, Michael Foord, Kamil Dworakowski, lthompson, romank, Jeff Brown, rridge, David Fraser, pobrien, ebaklund.

[ANN] Release 0.70.2 of Task Coach
by Jerome Laheurte Aug. 8, 2008

Aug. 8, 2008

Hi, I'm happy to announce release 0.70.2 of Task Coach. This release fixes some bugs and brings back the Fedora RPM. Bugs fixed: - Using the "Save selection" feature together with mail attachments could result in data loss. - Under KDE, the maximized state of the main window would not be restored. - One couldn't e-mail tasks with non-ASCII characters in their description. (SF#2025676) - Dragging an email message from Thunderbird and dropping it on Task Coach could give a "UnicodeDecodeError" on Fedora. (SF#1953166) - When an invalid regular expression was entered in a search control, no items were displayed. Additionally, if it was saved in TaskCoach.ini, TaskCoach would crash on launch later. - Mention of non-existing files in taskcoach.spec prevented the Fedora RPM from being built. - The category viewer would sometimes skip keyboard navigation or need an extra mouse-click to get focus. (SF#2020816, SF#2020812) - On Mac OS X, the keyboard shortcut for 'help' was interfering with the shortcut for 'hide window'. (SF#2006455) Features added: - Notes can be e-mailed. - Display a tool tip to warn user when a search string is an invalid regular expression. In this case, default to substring search. - Optionally put Task Coach in the user's startup menu so that Task Coach is started automatically when the user logs on (Windows only). (SF#2017400, SF#1913650) - Made (right-click) context menu's more consistent. Feature removed: - Don't supply the dummy recipient 'Please enter recipient' to the email program when mailing a task. This only forces the user to perform an extra action to remove that dummy text, while most if not all email programs will warn the user when she forgets to enter a recipient. (SF#2026833) What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org In addition to the source distribution, packaged distributions are available for Windows XP/Vista, Mac OS X, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Jérôme

Cryha - hasher and cipher in data bases [Feedback]
by Kless Aug. 7, 2008

Aug. 7, 2008

Cryha [1] allows to manage password hashs and encrypted text easily in data bases. Its main use is on web frameworks. I created a little TG2 project [2] with Cryha installed and configured to run, for if anybody wants to check that it is working well on its system. I need any *feedback* before of uploading the module to PyPi. * Before of use it, you need read the install file [3] Unzip archive, enter in directory and run:: $ cd test-cryha $ paster setup-app development.ini You can see the password that is stored as base-64:: $ cat data/schema_k See data in data base, to see as are stored passwords and emails:: $ sqlite3 devdata.db > .tables > SELECT * FROM tg_user; Check decrypting and login checking, and that both work with Unicode ('UTF-8'): $ paster shell u = model.User(password='yep', email='bar', nickname='foo') u.check_login('manager', 'managepassÑ') print u.decrypt_email('manager') [1] http://github.com/kless/cryha/tree/master [2] http://groups.google.com/group/tw-registra/files [3] http://github.com/kless/cryha/tree/master/INSTALL
