ANN: numarray-1.5.0
by Todd Miller 06 Dec '05

06 Dec '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-1.5.0 I. ENHANCEMENTS 1. Implementation of scipy newcore array interface and __array_struct__ support (supplying and consuming) for numarray. This should facilitate better interoperability with scipy newcore and Numeric. This protocol is documented here: http://numeric.scipy.org/array_interface.html but also in numarray's source code in Include/numarray/arrayif.h. Thanks to everyone who gave feedback on 1.4.1 and particularly to Francesc Altet for his diligent testing (and doctest) of Numeric<->numarray data interchange. II. BUGS FIXED / CLOSED 1365121 Definition of PyObject* operator conflicts with C++ 1350954 nummacro.h:27: error: expected type-specifier before ';' tok 1346470 Please document more of what byteswap and byteswapped do 1364215 Cannot combine array and masked array (e.g. via divide) 1363723 my_array = +my_other_array uncovers a bug 1364811 Infinite loop converting empty CharArrays to lists 1364815 Strange behaviour when creating empty Int32 arrays 1340983 Fix __get_array_data__ 1346480 byteswapped doesn't match doc string 1346425 Please document if copy "fixes" byte order 1346426 Please document what array does with numarray arrays See http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse for more details. III. CAUTIONS This release should be binary compatible with numarray-1.3.x. New extensions compiled against 1.5.0 may not work with prior versions of numarray. WHERE ----------- Numarray-1.5.0 windows executable installers, source code, and manual is here: http://sourceforge.net/project/showfiles.php?group_id=1369 Numarray is hosted by Source Forge in the same project which hosts Numeric: http://sourceforge.net/projects/numpy/ The web page for Numarray information is at: http://www.stsci.edu/resources/software_hardware/numarray Trackers for Numarray Bugs, Feature Requests, Support, and Patches are at the Source Forge project for NumPy at: http://sourceforge.net/tracker/?group_id=1369 REQUIREMENTS ------------------------------ numarray-1.5.0 requires Python 2.2.3 or greater.

ANN: Leo 4.4a4 released
by Edward K. Ream 06 Dec '05

06 Dec '05

Leo 4.4 alpha 4 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 To learn about Leo see http://webpages.charter.net/edreamleo/intro.html Leo 4.4 a4 redraws the screen more quickly, corrects numerous bugs in the 4.4 code base, and introduces several new features. You should be able to use this version safely. There are no known serious bugs, but several minibuffer commands are not ready for prime time. All the major features of 4.4 are in place. The highlights of Leo 4.4: ---------------------------------- - An Emacs-like mini-buffer: you can now execute any command by typing its long name. Support for tab completion. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Support for almost all commands in the Emacs Cmds menu, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. - Per-pane key bindings. You can bind shortcuts to multiple commands depending on which of Leo's panes presently has focus. For example, you can use arrow keys to move nodes in the outline pane, while retaining their defaults in Leo's body pane. Per-pane key bindings are essential for mouseless Leo. - @command nodes create minibuffer commands. You can bind key shortcuts to @button and @command nodes. - A rewrite of Leo's keystroke handling. In particular, Leo handles key events immediately rather than queuing them for idle time. - Leo recovers from crashes much more reliably than in any previous version. - Leo updates the screen immediately rather than waiting for idle time. This 'Newer World Order' simplifies the code and improves performance. Known bugs in Leo 4.4a4 ----------------------- - Several minibuffer commands do not work. See the release notes for details. Coming in later releases of Leo 4.4: ------------------------------------ - An auto-complete command that shows class members in the Completion tab. - More support for mouseless Leo. There will be commands to manipulate all aspects of Leo using commands, so your fingers will never have to leave the keyboard. - Support for Vim and other 'plain-key' input modes. -------------------------------------------------------------------- Edward K.

akismet 0.1.2, cgiutils 0.3.5, pathutils 0.2.3
by Fuzzyman 05 Dec '05

05 Dec '05

Hello All, A new release and two updates. New akismet.py 0.1.2 ================ Python Interface to the Akismet API Version 0.1.2 4th December 2005 http://www.voidspace.org.uk/python/modules.shtml#akismet `Akismet <http://www.akismet.com>`_ is a web service for recognising spam comments. It promises to be almost 100% effective at catching comment spam. They say that currently 81% of all comments submitted to them are spam. It's designed to work with the `Wordpress Blog Tool <http://wordpress.org/>`_, but it's not restricted to that - so this is a Python interface to the `Akismet API <http://akismet.com/development/api/>`_. You'll need a `Wordpress Key <http://wordpress.com>`_ to use it. This script will allow you to plug akismet into any CGI script or web application, and there are full docs in the code. It's extremely easy to use, because the folks at akismet have implemented a nice and straightforward {acro;REST;REpresentational State Transfer} API. It also comes with an `example CGI <http://www.voidspace.org.uk/cgi-bin/akismet/test_akismet.py>`_. (Although the akismet feature of an "example positive" doesn't seem to be working currently - there fault not mine :-) You can read the full (Python) docs at : * `akismet.py Docs <http://www.voidspace.org.uk/python/akismet_python.html>`_ Download it here : * http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=akismet-0.1.2… cgiutils 0.3.5 - pathutils 0.2.3 ===================== pathutils 0.2.3 November 26th 2005 cgiutils 0.3.5 November 26th 2005 http://www.voidspace.org.uk/python/recipebook.shtml#utils These two modules contain functions and constants for *'general'* use. They are both included as part of the `Voidspace Pythonutils Package <http://www.voidspace.org.uk/python/modules.shtml#pythonutils>`_ . (A new release of pythonutils - containing these updated modules - is due shortly). **Pathutils** contains various functions for working with files and paths. This includes (amongst other thing) : * Easy ways to iterate over files and directories * A function to calculate a relative path from one location to another * Several 'convenience' file reading/writing functions * `py2exe <http://www.py2exe.org>`_ directory support * A function for pretty printing file sizes * A simple solution to cross-platform file locking * Import from a specific location See the `pathutils Homepage <http://www.voidspace.org.uk/python/pathutils.html>`_. **CGI utils** has (guess what... {sm;:?:}) various functions for use with CGI. It contains functions to do things that every CGI has to cope with. They are most useful for simple scripts, where a full blown framework would be too cumbersome. It includes (amongst other thing) : * Functions for receiving form submissions * Cross platform functions to send emails (including creating {acro;HTML} emails) * A basic templating system * A {acro;DNS;Domain Name System} blacklist lookup * A function to generate a menu line for pages with lots of results See the `cgiutils Homepage <http://www.voidspace.org.uk/python/cgiutils.html>`_. Download them here : * http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=utils.zip (25k) (both modules) * http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=pathutils.py (19k)} * http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=cgiutils.py (20k)} {small;The zip file has text versions of the docs for these two modules.}

Flightdeck-UI Online Version 0.4.0 (Stable) Released
by George Belotsky 01 Dec '05

01 Dec '05

The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. Flightdeck-UI Online version 0.4.0 is the latest stable release of the Web-based dashboard/monitoring system based on these concepts. Here is the list of changes from the previous release (advanced beta version 0.3.91). * A bug in the "__getattr__" method of "CachedObject" (file "Flightdeck-UI/python/FdUI/engine/Cache.py" was corrected. * Minor whitespace inconsistencies were fixed in the following files. Flightdeck-UI/python/FdUI/apache/RemoteLogger.py Flightdeck-UI/python/FdUI/logic/_DrawPrimitives.py Flightdeck-UI/python/FdUI/util/Daemon.py * The stylesheet ("/docroot/fdui-resources/css/fdui.css") was updated to control the body colors, and eliminate validator warnings. The distribution includes detailed installation instructions and two example control panels. The installation is designed to be a very simple process -- please contact the author if you have questions. See the homepage: "http://www.openlight.com/fdui" or download directly from: "http://www.openlight.com/fdui/downloads/fdui-online-0.4.0.tar.gz". What is Flightdeck-UI --------------------- The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The web service version (Flightdeck-UI Online) retains the plug-in architecture of previous releases. Each plugin, however, may now be monitored at different sampling rates. Multiple data sources (hosts on the Internet, embedded devices, etc.) can be tracked simultaneously. Also, virtually any Unix command that you enter from the shell can be automatically executed by Flightdeck-UI Online, and the results displayed by the system's virtual instruments. Although the web service requires a Flash front end (developed using only the MTASC open source ActionScript compiler; see http://www.mtasc.org/) Flightdeck-UI Online is still primarily written in Python. The author welcomes any ideas and suggestions: please email them directly to "python(a)openlight.com". Best Wishes, George Belotsky.
