Flightdeck-UI -- a Cockpit for your Desktop (initial release)
by fdui＠openlight.com 25 Sep '02

25 Sep '02

The goal of the Flightdeck-UI project is to apply ideas from aircraft instrumentation design to general purpose user interfaces. The project homepage is at "http://www.openlight.com/fdui/". Flightdeck-UI is open source. It is written in Python and requires Tkinter. A whitepaper and the initial code release are available at the project website. The library modules in the current release include two virtual instruments (altimeter-style and VSI-style gauges) and a demonstration program. The demonstration program ("cmdwatch.py") will monitor the output of a Unix command of your choice (you also enter a regex filter and a numerical expression, so that the final result is a number), displaying the quantity and rate of change using two gauges on the screen. A "SHRINK" button puts up a small window with two scaled-down gauges, and hides everything else -- so you can keep it running in a corner of your screen. As a quick experiment, you can run several instances of "cmdwatch.py" to monitor multiple variables. A more comprehensive application -- the Multi-Variable Monitor "mvm.py" is being planned. Some good places to use Flightdeck-UI are operations centers that perform monitoring (typically 24x7), as well as tools for System Administrators who need to keep an eye on multiple machines while concentrating on other work. Questions can be emailed to originating address of this message. Have fun! George

ANN: eGenix.com mx EXPERIMENTAL Package 0.7.0
by M.-A. Lemburg 25 Sep '02

25 Sep '02

________________________________________________________________________ ANNOUNCING: eGenix.com mx EXPERIMENTAL Extension Package for Python Version 0.7.0 Experimental Python extensions providing important and useful services for Python programmers. ________________________________________________________________________ WHAT IS IT ?: The eGenix.com mx Experimental Extensions for Python are a collection of alpha and beta quality software tools for Python which will be integrated into the other mx Extension Packages after they have matured to professional quality tools. Python is an object-oriented Open Source programming language which runs on all modern platforms (http://www.python.org/). By integrating ease-of-use, clarity in coding, enterprise application connectivity and rapid application design, Python establishes an ideal programming platform for todays IT challenges. ________________________________________________________________________ WHAT'S NEW ? This release fixes a few minor bugs and solves the distutils problem with mxNumber. It also comes with an updated distutils setup which installs the RPMs into /usr/ rather than /usr/local/. ________________________________________________________________________ EGENIX.COM MX EXPERIMENTAL PACKAGE OVERVIEW: mxNumber - Python Interface to GNU MP Number Types mxNumber provides direct access to the high performance numeric types available in the GNU Multi-Precision Lib (GMP). This library is licensed under the LGPL and runs on practically all Unix platforms. eGenix.com has ported the GMP lib to Windows, to also provide our Windows users with the added benefit of being able to do arbitrary precision calculations. The package currently provide these numerical types: 1. Integer(value) -- arbitrary precision integers much like Python longs only faster 2. Rational(nom,denom) -- rational numbers with Integers as numerator and denominator 3. Float(value[,prec]) -- floating point number with at least prec bits precision 4. FareyRational(value, maxden) -- calculate the best rational represenation n/d of value such that d < maxden mxTidy - Interface to HTML Tidy (HTML/XML cleanup tool) mxTidy provides a Python interface to a thread-safe, library version of the HTML Tidy. command line tool. HTML Tidy helps you to cleanup coding errors in HTML and XML files and produce well-formed HTML, XHTML or XML as output. This allows you to preprocess web-page for inclusion in XML repositories, prepare broken XML files for validation and also makes it possible to write converters from well-known word processing applications such as MS Word to other structured data representations by using XML as intermediate format. mxURL - A URL Datatype mxURL provides a new datatype for storing and manipulating URL values as well as a few helpers related to URL building, encoding and decoding. The main intention of the package is to provide an easy to use, fast and lightwheight datatype for Universal Resource Locators (note the W3C now calls these URIs). mxUID - A UID Datatype mxUID provides a fast mechanism for generating universal identification strings (UIDs). The intent is to make these UIDs unique with high probability in order to serve as object or data set identifiers. A typical use lies in generating session IDs. Other areas where unique IDs play an important role are RPC-implementations, ORBs, etc. ________________________________________________________________________ WHERE CAN I DOWNLOAD IT ? The download archives and instructions for installing the packages can be found at: http://www.egenix.com/ Note that in order to use the eGenix.com mx EXPERIMENTAL package you will first need to install the eGenix.com mx BASE package which can be downloaded from the same location. ________________________________________________________________________ WHAT DOES IT COST ? The EXPERIMENTAL packages uses different licenses in its subpackages. Please refer to the subpackage documentation for details. Some of them may be integrated into the BASE package, others will be integrated into the COMMERCIAL package. The package comes with full source code ________________________________________________________________________ WHERE CAN I GET SUPPORT ? Commercial quality support for these packages is available from eGenix.com. Please see http://www.egenix.com/files/python/eGenix-mx-Extensions.html#Support for details about our support offerings. ________________________________________________________________________ Enjoy, -- Marc-Andre Lemburg CEO eGenix.com Software GmbH ______________________________________________________________________ Company & Consulting: http://www.egenix.com/ Python Software: http://www.lemburg.com/python/

ANN: Python FAM
by Robert Sander 25 Sep '02

25 Sep '02

Hi! I would like to announce release 1.0.1 of Python FAM. http://python-fam.sourceforge.net/ Python FAM is a port (or wrapper module) of libfam from the File Alteration Monitor project at http://oss.sgi.com/projects/fam/. The included test.py does everything test.c++ (the original example) does, so I am quite confident that it works. ;-) This is my first adventure in the large world of extending Python with C modules. Therefore feedback is very appreciated. Greetings -- Robert Sander Manager Information Systems www.epigenomics.com Kastanienallee 24 +493024345330 10435 Berlin

ANN: Python CVS RDF news feeds
by Dinu Gherman 25 Sep '02

25 Sep '02

I'm making available RDF news files with pointers to the latest changes in the Python (and ReportLab) CVS repositories (using ViewCVS on SourceForge): http://me.in-berlin.de/~darwin/cvspysf.rdf (Python, 48 h) http://me.in-berlin.de/~darwin/cvsrlsf.rdf (ReportLab, 72 h) There is also one such file for Stackless Python, but given that there is no ViewCVS for it (yet), the links point some- where into Nirwana: http://me.in-berlin.de/~darwin/cvsstpy.rdf (Stackless, 72 h) All are updated each hour. You can point any GUI tools like SlashDock* (on OS X) to them and save time by forgetting about typing the respective URLs or CVS commands for quickly tracking changes. BTW, another interesting news file is ActiveState's one, which will let you keep an eye on the newest Python recipes in their cookbook website: http://aspn.activestate.com/ASPN/Cookbook/Python/index_rss Regards, Dinu * http://homepage.mac.com/stas/slashdock.html

[ANN] Latest Puffin Article on IBM's developerWorks
by A. Keyton Weissinger 25 Sep '02

25 Sep '02

IBM has just published the latest article on the Puffin Automation Framework. Check it out: http://www.ibm.com/developerworks This article introduces the new architecture and the future of the system. What is the Puffin Automation Framework? As it's name implies, Puffin allows you to automate "actions." An action, in terms of Puffin, is any "high level" execution item that may require inputs, may produce outputs, and whose results may be validated for success or failure. For example, an action may involve making an HTTP request to a dynamic web page. It may involve grabbing a file's contents or even retrieving a specific email based on a keyword in the subject line. All of these are actions in the sense that they can be automated by Puffin. Puffin will manage all inputs, outputs, and validation for these actions.
