ANN: MkSQL release 0a0
by Gordon McMillan 02 Sep '01

02 Sep '01

The first alpha release of MkSQL is here: http://www.mcmillan-inc.com/mksqlintro.html What is it? MkSQL is a Python package which implements a SQL front end to the MetaKit database. It implements a large subset of the SQL 2 (aka SQL 92) standard, and comes with a Python DBI version 2 interface. Prerequisites: Python 2.1 (or later). MetaKit 2.4 including the metakit.py wrapper. mx.TextTools from the egenix mxBase package. (Links on page referenced above). More Details: MkSQL can be used to query or update any existing MetaKit database which has a relational structure. Basically that means that subviews are ignored. In addition, if you use MkSQL to define your database structure, MkSQL will enforce integrity constraints on all update, insert and delete statements. Note that MkSQL is not a database server. MetaKit is an embedded database, and MkSQL does nothing to change that. License: MIT license. Contact: gmcm(a)hypernet.com <P><A HREF="http://www.mcmillan-inc.com/mksqlintro.html"> MkSQL release 0a0</A> A SQL front-end for MetaKit (cross-platform). (28-Aug-01) - Gordon

[Module] QuantLib-Python
by Ferdianando Ametrano 31 Aug '01

31 Aug '01

QuantLib-Python ---------------- A module for quantitative finance QuantLib-Python is a module for quantitative finance. It is a SWIG wrap of QuantLib, a C++ open source library. The QuantLib project is aimed to provide a comprehensive software framework for quantitative finance. The goal is to provide a standard free/open-source library to quantitative analysts and developers for modelling, trading, and risk management in real-life. QuantLib plans to offer tools that are useful for both practical implementation, with features such as market conventions, solvers, PDEs, etc., and advanced modelling, e.g., exotic options and interest rate models. QuantLib is for academics and practitioners, eventually promoting a stronger interaction between the two.

Python 2.1.1-3 RPMs updated with LFS
by Sean Reifschneider 31 Aug '01

31 Aug '01

Guido has put up my RPMs for Python 2.1.1 (thanks) at: http://www.python.org/2.1.1/rpms.html This includes Large File Support which enables the writing of files larger than 2GB. This also works around the problem with the interpreter exiting when a file reaches 2GB. Included above are links to the SRPM (which includes tunable entries at the top of the .spec file. Also included are binary RPMs built against RedHat 7.1. To build binaries for your specific system, download the .src.rpm and do "rpm --rebuild python2-2.1.1-3.src.rpm", or install it and modify the settings in the .spec file, then rebuild with "rpm -ba python-2.1.spec". Enjoy, Sean -- Today's robots are very primitive, capable of understanding only a few simple instructions such as 'go left', 'go right', and 'build car'. -- John Sladek Sean Reifschneider, Inimitably Superfluous <jafo(a)tummy.com> tummy.com - Linux Consulting since 1995.

[Application] Global Digital Elevation Model Data Viewer Python Script
by Tom Babbitt 31 Aug '01

31 Aug '01

Global Digital Elevation Model Data Viewer Python Script -------------------------------------------------------- Viewer for GTOPO30 - Global Topographic Data The program starts by opening a DEM (Digital Elevation Model) file. This program requires the .dem file, the .gif file and the .hdr file from the GTOPO30 archive. The right panel contains controls for setting the Longitude, Latitude and size of the area to be rendered. You can also set the area using the mouse. When you are done selecting the area press the Refresh button on the left panel to display the 3D image. The left panel controls set the rotation angle, the angle above the horizon and the distance in pixel units out from the center for the grid type of rendering. The Display control selects the type of rendering method. You can change any of these factors and just press the Refresh button to display changes. I have only tested this out on Win 98.

[announce] Roundup issue tracker version 0.2.8
by Richard Jones 30 Aug '01

30 Aug '01

Roundup 0.2.8 - an issue tracking system This is a bugfix release. Fixed: . Missing import in mailgw. Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.0+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates and three database back-ends. Back-ends for relational databases are being developed. Source is available at the website: http://sourceforge.net/projects/roundup/

[Application] mwsynth / 1.0
by Parnassus Submission 30 Aug '01

30 Aug '01

mwsynth / 1.0 ------------- mwsynth converts a text file to speech using the pronounciation feature of an online dictionary mwsynth performs speech synthesis on the text in a given input file, using the word pronounciation feature of an online dictionary. It outputs a series of numbered .wav files, which when played in ascending order, sound roughly like the text of the input file being spoken aloud. A CR separated playlist is also generated, which can be used with XMMS or WinAMP to easily play the files in the correct order. This tool is not intended for serious use, and really just constitutes a lighthearted attempt to demonstrate a mostly functional speech synthesis system in ~80 lines or so of Python. Comments and questions are welcome, although I don't intend to develop the application further.

[announce] Roundup issue tracker version 0.2.6
by Richard Jones 29 Aug '01

29 Aug '01

Roundup 0.2.7 - an issue tracking system This is predominantly a bugfix release. Feature: . Text searches are now case insensitive. All forms of text search use regular expressions now. Fixed: . Had another 2.1-ism in the unit tests . Made the mail parser a little more robust w.r.t missing Subject: (both thanks Mikhail Sobolev) . Missed some isFooType usages (thanks Mikhail Sobolev for spotting them) . Reverted back to sending change messages to the web editor of a node so that the change note message is actually generated. . CGI interface wasn't generating correct change messages. . Notes entered during a change are saved to the messages list even if there's no nosy list. No message is generated if there's no nosy list and there's no change note (since it would just duplicates the journal). . Completely removed the bsddb3 module from the tests - will be reinstated when the http://bsddb.sourceforge.net/'s bugs #439959 and #456408 are dealt with. One is fixed in CVS, the other pending. Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces.

[Module] Python Frame Buffer
by David Pettersson 28 Aug '01

28 Aug '01

Python Frame Buffer ------------------- Simple graphics drawing extension with minimal event handling. The frame buffer extension was intended as a simple aid, because I always found myself hacking together some sort of way to present iterative improvement in my algorithms (e.g. shortest path, traveling salesperson problem etc). This module simplifies drawing simple things like that a lot. All that is needed to draw a line is: import fb f = fb.FrameBuffer() f.open(100, 100, 'Line Example') f.line(10, 10, 50, 50) It could also be useful when teaching younger students (or those new to Python and computer graphics) graphical algorithms. Any feedback is welcome.
