Announce: PythonD 2.2.1 Release 2.0 development platform for DOS
by bdeck 25 Jul '03

25 Jul '03

Python is an interpreted, interactive, object-oriented programming language. PythonD is a 32-bit, multi-threaded, networking- and OpenGL-enabled Python interpreter for DOS and Windows. **************************************************************************** ******* ANNOUNCEMENT: PythonD 2.2.1 Release 2.0 is now available for public download at: http://members.lycos.co.uk Many additional modules are also available for download including: Reportlab 1.15 PDF library PyHL HDF5 file format library Gnome LibXML2 and LibXSLT modules (based on LibXML2 2.5.8) PyXML 0.82 PyNumeric 23.0 Previous versions of these PythonD modules are no longer usable, as the DXE file format has changed. **************************************************************************** ******* ENHANCEMENTS and FIXES over last (1.13) Release: PythonD now passes more that 145 tests (155 in verbose mode) Threading. PythonD attempts the first multi-threaded posix scripting engine for DOS. Thanks to R. Dawe for his pth threads patch. Added PyOpenGL using Mesa 5. Some demos provided. Added Python Imaging Library Added dbmmodule Upgraded socketmodule with new Wattcp-32 2.2.4 release. New DXE format & Many additional C and Assembly tokens added to export list. re-compiled with newest DJGPP 2.0.4 alpha libraries. DJGPP's 'FNCASE' variable is automaticaly set to 'y' during PythonD sessions. This may be turned off by commenting out the appropriate lines from site.py. This is currently only activated during NT sessions. 'commands' module hacked for DOS/DJGPP. Requires 'bash.exe'. copy_absolute() in getpath.c has been fixed for DOS-DJGPP... consequently, 'sys.executable' now returns the correct value. *limited* library support for 8.3 OSes (pure DOS without LFN driver). PythonD standard library found in: os.path.join(prefix, "lib", "python" + sys.version[:1]) the standard declaration uses 'sys.version[:3]' This is for dos 8.3 compatibility (one library for both LFN and non-LFN!). posixpath.abspath() fixed for DOS/DJGPP. site.py loads error-free on non-djgpp systems. Networking exceptions have been added to the list kept in the errno module. Socketmodule now initializes upon module import. Requires packet driver. Somewhat better selectmodule build. Added select.poll() (from Wattcp). Note that select.poll() is largely untested. Other small fixes I want to thank those whose work greatly helped to make this release possible, including: Daniel Borca Richard Dawe Charles Sandmann Regards, Ben Decker

RELEASED Python 2.3c2
by Barry Warsaw 24 Jul '03

24 Jul '03

Python 2.3c2 is the second and last release candidate for Python 2.3. There have been a bunch of bug fixes and memory leak plugs since the first release candidate, but no new features. As described in PEP 283, Python 2.3 final will be released before the end of July 2003. We are planning for Tuesday 29-Jul-2003 if everything looks good. We highly encourage everyone to rigorously test this release candidate. Only critical bug fixes will be allowed from here to the final release, but we want this release to be as stable as possible. Highlights since rc1 include: - It is now possible to import from zipfiles containing additional data bytes before the zip compatible archive. Zipfiles containing a comment at the end are still unsupported. - Fixed leaks in pyexpat and locale, and a long standing bug in the parser module. - The MacOSX build is now built with -mno-fused-madd to fix test_coercion on Panther (OSX 10.3). For more highlights, see http://www.python.org/2.3/highlights.html Other new stuff since Python 2.2: - Many new and improved library modules, e.g. sets, heapq, datetime, textwrap, optparse, logging, bsddb, bz2, tarfile, ossaudiodev, and a new random number generator based on the highly acclaimed Mersenne Twister algorithm (with a period of 2**19937-1!). - New builtin enumerate(): an iterator yielding (index, item) pairs. - Extended slices, e.g. "hello"[::-1] returns "olleh". - Universal newlines mode for reading files (converts \r, \n and \r\n all into \n). - Source code encoding declarations. (PEP 263) - Import from zip files. (PEP 273 and PEP 302) - FutureWarning issued for "unsigned" operations on ints. (PEP 237) - Faster list.sort() is now stable. - Unicode filenames on Windows. - Karatsuba long multiplication (running time O(N**1.58) instead of O(N**2)). To report problems, use the SourceForge bug tracker: http://sourceforge.net/tracker/?group_id=5470&atid=105470 brought-to-you-by-the-letter-'D'-for-drifty-ly y'rs, -Barry

open source applicatons foundation is hiring python hackers
by Bart Decrem 24 Jul '03

24 Jul '03

Hi folks, During boom years, this message would definitely be spam, but in those lean years, I'm hoping that it's not quite a mortal sin to post this announcement on the Python list, especially since Chandler is entirely build in Python. I'm helping with recruiting for the open source applications foundation in San Francisco. Mitch Kapor, who runs OSAF, is (m)itching to speed up development on Chandler, an innovative open source PIM project, but the team is chronically understaffed. I think Chandler has great potential. Rather than try to explain it myself, here's how Mitch explains it: http://www.osafoundation.org/Chandler_Compelling_Vision.htm. In addition to working on a very interesting open source end-user application, there's a couple of other really compelling things about working at OSAF: - The team: It's an amazing group of people: Mitch Kapor, Andy, Michael Toy (who pushed a bunch of Netscape releases out the door), John Anderson (who wrote WriteNow), Mitchell Baker (of Mozilla fame). See the people page at http://www.osafoundation.org/people.htm - A hub for interesting open source initiatives. OSAF is helping the Mozilla Foundation get off the ground and we're working on several other significant open source initiatives - An incredible office: Really cool digs, south of Market, dog friendly - Great, relax work environment, no 80 hour weeks. Below is an overview of what kind of people we're looking to hire. Please send me mail (bart(a)decrem.com) if you're interested or know people I should be talking to. Bart Decrem OSAF Hiring Wishlist OSAF is looking for people of all shapes and sizes. Obviously we would like to hire the best people we can find. All people we are looking for would: • Live in San Francisco or be willing to commute to San Francisco three days a week • Have significant experience with object oriented languages • Be able to understand and work with large bodies of code they did not write without getting too cynical. • Be fun to hang out with. It would be nice, but not necessary for people to also have: • Significant experience working with a functional language • Python experience • Strong contribution to other open source projects As our plans for the future are still sketchy, it is impossible to write complete job descriptions for the people we want to hire, we would be happy to hire people with combinations of these skills. User Interface Implementation. Someone needs to turn the pretty drawings into something which works spectacularly well. This person would ideally have worked on well though of end-user software on more than one platform and be proud to show off her or his past work. Network Internals Architect – Inside Chandler will be a component which manages asynchronous data streams from many different sources and provides the plumbing for Chandler. We need someone who can design and implement this. E-Mail data wizard. We will need someone to evaluate exiting code for communicating with e-mail servers and parsing e-mail messsages, make a fix/build decision, and then hook it to the networking and data repository frameworks. wxPython platform wizard. Someone who is familiar with with win32, gtk and mac toolbox who can help us polish wxwindows to be a modern ui platform. Toolkit implementor – Someone who has written a fair share of UI toolkits in their life and would be interested in helping us extend wWindows into a fairly high-level toolkit for data based applications. Indexing expert. Chandler will require full text indexes for constantly changing data, we need someone to show us the way. We will need rich text editing and HTML display in wxWindows. Someone familiar with parts of this landscape who could take us where we need to go would be excellent. Gecko/Konqueror, CSS, XBL, XSL, yadda yadda yadda. qa coordinator – eventually there will be some community based qa effort with an osaf contact managing the work. this person needs to be able to evaluate the quality of tests and to be fliexible in choosing approaches to testing and verification. It is unlikely that someone from a QA organization will be able to do this job. tech writer – it would be good to have someone who wrote well, it would be nice if that person also had some other skill on this list Another development manager. We imagine the org chart will eventually require the hirhing of a second manager. This person needs to be organized enough to provide structure, but not so organized that they provide calicification.

[ANN] Pymprovisator 0.1 released
by forodejazz＠yahoo.es 24 Jul '03

24 Jul '03

Hi all! I've released the first version of my program Pymprovisator. Pymprovisator is a program that emulates the program Band in a Box from PG Music. You can think in it like the electronic version of the books+CD from Jamey Aebersold. You set the basic parameters in a jazz song (title, style, key, chords sequence,...) and the program will generate a Midi file with the correct accompainment. Pymprovisator is written in Python and Tkinter, and needs some auxiliary programs: abc2midi (http://abc.sourceforge.net/abcMIDI/) and a MIDI player (on Windows boxes, Windows Media Player is a good choice; on other systems, you can use playmidi, timidity, kmid or another program). Pymprovisator runs on several operating systems: Windows, Linux, FreeBSD, BeOS, MacOS and many other O.S. The program is available at http://www.angelfire.com/jazz/forodejazz/ Happy playing! -- David Asorey Álvarez Mail: forodejazz (at) yahoo (dot) es Web (spanish): http://www.geocities.com/forodejazz/programacion/

[ANN] py2exe 0.4.1 released
by Thomas Heller 24 Jul '03

24 Jul '03

py2exe is a distutils extension to convert python scripts into windows exe-files (plus a few dlls), able to run on computers without requiring a python installation. New in release 0.4.1: Integrated support for dll and exe COM servers, contributed by Mark Hammond. Thanks! Much better modulefinder module from Python 2.3 included. The build process should now give a lot less warnings and better results. py2exe now is compatible with PyXML, for example. The support of Python 2.3 is still preliminary, and has to be improved. I intend to use the new zipimport feature instead of good old imputil. Thanks to Just van Rossum for his work on both the zipimport and the improved modulefinder. Download from the usual location: http://starship.python.net/crew/theller/py2exe/ Enjoy, Thomas

ANN: numarray-0.6
by Todd Miller 23 Jul '03

23 Jul '03

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, and improved type promotions. I. ENHANCEMENTS 1. Repackaging numarray has been modified from a collection of Python modules into a Python package. See Doc/Repackaging in the source distribution for more details. 2. Median Filter Function See numarray.image.combine.median for a function which computes the median pixels in a stack of images. 3. Thread Safety Work Modifications to ufunc caching and IEEE error handling enable numarray to work in multi-threaded programs. This is barebones support, not thread awareness. II. BUGS FIXED 733534 Broadcasts of non-array sequences fails 733535 NA_typeNoToTypeObject sometimes fails 736674 PyArray_ContiguousFromObject() fails for some scalars 750320 CharArray.raw() is broken 750326 building RPMS fails 754836 Missing Src/_convmodule.c during setup 756050 chararray multi-d copy fails for recarray 772519 memory.new_memory() 64-bit scanning bug III. CAUTIONS 1. Due to the distribution repackaging, numarray-0.6 will not install correctly on top of an existing numarray installation. Before installing numarray-0.6 remove your old version of numarray. IV. REQUIREMENTS numarray-0.6 requires Python 2.2.2 or greater. V. AUTHORS Numarray was written by Perry Greenfield, Rick White, Todd Miller, JC Hsu, Paul Barrett, Phil Hodge at the Space Telescope Science Institute. Thanks go to Jochen Kupper of the University of North Carolina for his work on Numarray and for porting the Numarray manual to TeX format. Thanks also to Edward C. Jones, Francesc Alted, Paul Dubois, Eric Jones, Travis Oliphant, Pearu Peterson, Konrad Hinsen, and everyone who has contributed with comments and feedback. VI. LICENSE Numarray is made available under a BSD-style License. See LICENSE.txt in the source distribution for details. VII. WEB PAGE <P><A HREF="http://www.stsci.edu/resources/software_hardware/numarray">numarray 0.6</A> - array processing extension supporting records and memory mapping. (18-07-03)
