[ANNOUNCE] gmpy 1.0 alpha released
by Alex Martelli 13 Nov '05

13 Nov '05

See http://gmpy.sourceforge.net/ for details. What is it: a wrapper for the GMP library, to provide multi-precision arithmetic for Python. Multi-precision floats, and unbounded-precision rationals, are not present in stock Python; multi-precision integers ('long') are, but gmpy's version of multi-precision integers is faster for some operations (NOT all -- used to be, but Python 2.3 did serious enhancements to some operations on longs) and provides lots of nifty pre-packaged additional functions. Minor changes and bug-fixes since the latest 0.9 pre-alpha; support for Python 2.3. The Windows binary release is now for Python 2.3 _only_ (if you're stuck with Python 2.2 on Windows, you can keep using gmpy 0.9 pre-alpha and not really suffer from that). Known bug on Windows: the scan0 and scan1 functions appear broken (perhaps related to the lack of a GMP 4.0 library for Windows -- haven't found one around yet). Alex

[ANN] mlabwrap v0.9 released
by Alexander Schmolck 27 Feb '05

27 Feb '05

This release just adds OS X support to setup.py (thanks to Josh Marshall). I've also made some recent improvements to the website, based on user feedback. In the absence of any bug reports so far I'd tentatively consider mlabwrap as stable. Dowload from: <http://mlabwrap.sourceforge.net/> What is mlabwrap? ----------------- A high-level python to matlab(tm) bridge (low-level access is also possible). It should work with recent python >=2.3 and matlab(tm) >=6.0 versions and under practically any supported by both matlab and python (I'm using linux myself, but thanks to user feeback windows and OS X should also work fine). Here is a short demo snippet: >>> from mlabwrap import mlab >>> import Numeric >>> mlab.lookfor('singular value') GSVD Generalized Singular Value Decompostion. SVD Singular value decomposition. [...] >>> help(mlab.svd) mlab_command(*args, **kwargs) SVD Singular value decomposition. [U,S,V] = SVD(X) produces a diagonal matrix S, of the same dimension as X and with nonnegative diagonal elements in [...] >>> mlab.svd(array([[1,2], [1,3]])) array([[ 3.86432845], [ 0.25877718]]) 'as

ANN: PyQwt3D-0.1 released
by Gerard Vermeulen 27 Feb '05

27 Feb '05

What is PyQwt3D? - it is a set of Python bindings for the QwtPlot3D C++ class library which extends the Qt framework with widgets for 3D data visualization. PyQwt3D inherits the snappy feel from QwtPlot3D. The examples at http://pyqwt.sourceforge.net/pyqwt3d-examples.html show how easy it is to make a 3D plot and how to save a 3D plot to an image or an (E)PS/PDF file. - it requires and extends PyQt, a set of Python bindings for Qt. - it supports the use of PyQt, Qt, Qwt, the Numerical Python extensions (either Numeric, or numarray or both) and optionally SciPy in a GUI Python application or in an interactive Python session. - it runs on POSIX, MacOS/X and Windows platforms (practically any platform supported by Qt and Python). The home page of PyQwt3D is http://pyqwt.sourceforge.net. PyQwt3D-0.1 supports: 1. Python-2.4 downto -2.3. 2. PyQt-3.14 downto -3.12. 3. SIP-4.2 downto -4.0, but SIP-4.2 is recommended. PyQwt3D does *not* support SIP-3.x (I tried, but failed). 4. Qt-3.3.4 downto -2.3.0. 5. QwtPlot3D-0.2.4-beta. Have fun -- Gerard Vermeulen

by Ransdell, Robert Ethan 26 Feb '05

26 Feb '05

Hexerei 1.1! Description Hexerei is a colorful software package for Python (and optionally a web server) that assigns a color value to each word or letter in a database. Hexerei then utilizes the PIL to convert produce an image consisting of color blocks which correspond to the given text. Thus, "a thousand words" become a picture! I have provided sourcecode access in HTML format for anyone to view. As all the important functions are in a few scripts and run by another script, it is simple for users to import the code and run it from a command line or interpreter. Features - Just set the permissions (with a web server) and run the code! - Tools are included for creating XHTML files on-the-fly. - Preferences can be set for many features. - Simple text documents are store encountered words and letters and to maintain a list of statistics. Licensing Hexerei is released under the GNU GPL.

XP / Python Code Sprint 4/9-10 in Portland, Oregon
by Arlo Belshee 25 Feb '05

25 Feb '05

XPDX will be hosting a code sprint on April 9-10, 2005 in downtown Portland, Oregon. A code sprint is a gathering of a bunch of programmers to complete a short, rapid development project. It allows developers from different companies to work together and learn from each other. It's also a fun weekend where we can make some impressive advances in interesting projects. This code sprint will be focused on two things: Extreme Programming and Python. Come pair with long-time XPers to learn from their experience. Or, pair with people from other backgrounds to get a fresh look at your own practices. We are focusing on Python because it is a new language to many in XPDX, and one that works well with XP. Also, Python integrates tightly with other common XP languages, allowing us to easily blend in XP work in a number of different areas. Currently, people have expressed interest in the following languages. * Pure Python. * Python and C++, via boost.org's boost::python interoperability template library. * Python and Java, via Jython. * Python and .Net, via Iron Python. * And probably some Smalltalk, just because. This is not a pure Python sprint. Please feel free to come if you've never even heard of the language. Many of us will be learning it this weekend. Also, if you have no interest in Python, come anyway. There will be a lot of work in Java and C++, and a smattering of other options. We are organizing this sprint via the XPDX area of the C2 wiki, at [http://c2.com/cgi/wiki?XpCodeSprint].Please visit that page for up to date information or to sign up. If anyone has a project that they want to work on, please add it to the wiki. Here are some get us started. * http://pythoncard.sourceforge.net/ * http://moinmoin.wikiwikiweb.de/, or MoinMoin plugins. * http://scons.sourceforge.net/ * 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. Glue together existing products, and provide a single installer that will configure the whole suite. If anyone knows of one of these currently in progress, please update the page to add a link. * How about a rocket telemetry data analysis or visualization tool for http://psas.pdx.edu/? We could even provide live hardware. 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. If you have additional questions, please email me. I look forward to pairing with you.

ANN: ViTables 1.0 beta - A GUI for PyTables files
by Francesc Altet 25 Feb '05

25 Feb '05

Announcing ViTables-1.0b ------------------------ I'm happy to announce the availability of ViTables-1.0b, the new member of the PyTables family. It's a graphical tool for browsing and editing files in both PyTables and HDF5 format. As it happens with the entire PyTables family, the main strength of ViTables is its ability to manage really large datasets in a fast and comfortable manner. For example, with ViTables you can open a table with one thousand millions of rows in a few tenths of second, with very low memory requirements. In this release you will find, among others, the following features: - Display data hierarchy as a fully browsable object tree. - Open several files simultaneously. - Reorganize your existing files in a graphical way. - Display files and nodes (group or leaf) properties, including metadata and attributes. - Display heterogeneous entities, i.e. tables. - Display homogeneous (numeric or textual) entities, i.e. arrays. - Zoom into multidimensional table cells. - Editing capabilities for nodes and attributes: creation/deletion, copy/paste, rename... - Fully integrated documentation browser Moreover, once CSTables (the client-server version of PyTables) will be out, ViTables will be able to manage remote PyTables/HDF5 files as if they were local ones. Platforms --------- At the moment, ViTables has been fully tested only on Linux platforms, but as it is made on top of Python, Qt, PyQt and PyTables, its portability should be really good and should work just fine in other Unices (like MacOSX) and Windows. Note for Windows users: Due to license issues, commercial versions of Qt and PyQt are needed to run ViTables on Windows platforms. Furthermore, those libraries must be packaged in a special manner to fulfill some special license requirements. An installer that handles properly these issues is being developed. A Windows version of ViTables will be published as soon as the installer development finishes. Current development state ------------------------- This is a beta version. The first stable, commercial, version will be available late on Mars. What is in the package ---------------------- In the package you will find the program sources, some info files as README, INSTALL and LICENSE, and the documentation directory. Documentation includes the User's Guide in HTML4 and also the xml source file, so you can format it as you want. Finally, those of you interested in the internals of ViTables can find the documentation of all its modules in HTML4 format. Legal notice ------------ Please, remember that this is commercial software. The beta version is made publically available so that beta testers can work on it, but the terms of the license must be respected. Basically it means that the software or its modifications cannot be distributed to anybody in any way without Cárabos explicit permission. See the LICENSE file for detailed information. Share your experience --------------------- Let me know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy Data with ViTables, the troll of the PyTables family! -- >qo< Francesc Altet http://www.carabos.com/ V V Cárabos Coop. V. Enjoy Data ""

ANN Leo 4.3-a3 Outlining IDE
by Edward K. Ream 25 Feb '05

25 Feb '05

Leo 4.3 alpha 3 is now available at http://sourceforge.net/projects/leo/ Leo 4.3 is the culmination of more than five months of work. This alpha 3 release corrects various bugs in Leo's core and in plugins. This is the first release that include an installer for MacOSX. The defining features of Leo 4.3: --------------------------------- 1. Leo now stores options in @settings trees, that is, outlines whose headline is '@settings'. When opening a .leo file, Leo looks for @settings trees not only in the outline being opened but also in various leoSettings.leo files. Users can create arbitrarily complex user options with @settings trees. Leo settings outlines are, in fact, infinitely more flexible and powerful than any scheme based on flat text. Readers of Python's configParser shootout take note. 2. The Preferences command temporarily replaces the outline pane with an outline showing all the @settings trees in effect. The Preferences command also replaces the body pane with a "settings pane". This settings pane allows you to change the settings selected in the outline pane using standard gui widgets. 3. Leo's read/write code in leoAtFile.py has been rewritten to support user-defined tangling and untangling. This is a major cleanup of Leo's core. 4. Leo now boasts an excellent Plugins Manager plugin. This plugin enables and disables plugins automatically and tells you everything you need to know about each plugin. This plugin also lets you download plugins from Leo's cvs site. 5. You can install third-party extensions in Leo's extensions directory. Leo will attempt to import such extensions from the extensions directory when normal imports fail. The distribution contains Python Mega Widgets in the extensions directory. What people are saying about Leo -------------------------------- "[Leo] should either replace or greatly augment the development tools that I use." -- Zak Greant "Leo is a marriage of outlining and literate programming. Pure genius. The main reason I am impressed with this tool is that it doesn't affect your choice of tools. You can use whatever IDE for whatever language and switch back and forth between Leo and it." -- Austin King "Leo is the best IDE that I have had the pleasure to use. I have been using it now for about 2--3 months. It has totally changed not only the way that I program, but also the way that I store and organize all of the information that I need for the job that I do." -- Ian Mulvany "I only have one week of Leo experience but I already know it will be my default IDE/project manager...people complain about the lack of a project manager for the free/standard Python IDE's like Idle. Leo clearly solves that problem and in a way that commercial tools can't touch." -- Marshall Parsons "[Leo has] become my main development platform, and I do this for a living. -- Nicola Larosa "I have been using Leo for about 3 weeks and I hardly use my other programming editor anymore...I find it easy and enjoyable to use. I plan to adopt it as my presentation tool for code reviews." -- Jim Vickroy "I'm absolutely astounded by the power of such a simple idea! It works great and I can immediately see the benefits of using Leo in place of the standard flat file editor." -- Tom Lee, <tomlee(a)bigpond.net.au> I think you're really showing what open source can do and your current trajectory puts you on track to kick Emacs into the dustbin of computing history. -- Dan Winkler More quotes at: http://webpages.charter.net/edreamleo/testimonials.html What makes Leo special? ----------------------- - Leo's outlines add a new dimension to programming. - Leo shows you your code and data the way _you_ want to see them. - Leo extends, completes and simplifies literate programming. - Leo's script buttons bring scripts to data. What is Leo? ------------ - A programmer's editor, an outlining editor and a flexible browser. - A literate programming tool, compatible with noweb and CWEB. - A data organizer and project manager. Leo provides multiple views of projects within a single outline. - Fully scriptable using Python. Leo saves its files in XML format. - Portable. leo.py is 100% pure Python. - Open Software, distributed under the Python License. Leo requires Python 2.2.1 or above and tcl/tk 8.4 or above. Leo works on Linux, Windows and MacOs X.
