SC-Corporate-ID release
by Philippe C. Martin May 6, 2005

May 6, 2005

Dear all, I am very pleased to announce the release of SC-Corporate-ID. SC-Corporate-ID is a commercial Smart Card security system that can be extended by the user using the Python language. SC-Corporate-ID is written in Python and wxPython for the most part (except for the PCSC wrapper, the GINA dll and the crypto) on the PC side, and in .... other languages on the Smart Card side. The PCSC driver (PYCSC) and the crypto (PYCRYPTO) are public domain packages (PYCSC was slightly modified by us) SC-Corporate-ID is an off-the shelf package: you can use it as is; yet, as it is based on a set of libraries (SCF), it can be modified and customized by the company using it (the restriction being the capabilities of the code in the Smart Card which would have to be modified by us). SC-Corporate-ID can be used for PC Access, Data Security (file encryption/signature), Company Electronic Purse and Corporate Identification. Some of its possible extentions are Building Access and WEB Security. SC-Corporate-ID cards can be delivered pre-programmed (firwmare + data) or simply with the firmware so the user may handle its own cards issuance. Although it is a commercial product, SC-Corporate-ID intends to be a true low cost security solution for Corporations. SC-Corporate-ID will soon be followed by a School/University ID as well as an Health Card ID. You may find information on SC-Corporate-ID at www.snakecard.com. Best regards, Philippe Martin

by Frank Niessink May 5, 2005

May 5, 2005

Hi all, I'm pleased to announce release 0.36 of Task Coach. New in this release: Bug fixed: - Descriptions loose newlines after reload (1194259). Feature added: - French user interface added, thanks to Jerome Laheurte. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://taskcoach.niessink.com https://sourceforge.net/projects/taskcoach/ A binary installer is available for Windows XP, in addition to the source distribution. Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

[ANN] Voidspace Guestbook 1.4.2
by Fuzzyman May 5, 2005

May 5, 2005

Oops, embarrasing bugix release time. Guestbook 1.4.1 worked fine (wonderfully even) with Python 2.4, but not with Python 2.3. This release fixes that, and also another Python 2.2 compatibility problem (yes I'm testing now...). Homepage : http://www.voidspace.org.uk/python/guestbook.html Example : http://www.voidspace.org.uk/cgi-bin/voidspace/guestbook2.py Quick Download : http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=guestbook.zip I might even have spelt my domain name right this time...

[ANN] PuLP 1.1: A Python Linear Programming modeler
by Jean-Sebastien Roy May 5, 2005

May 5, 2005

I would like to announce the release of PuLP v 1.1. PuLP is an LP modeler written in python. PuLP can generate MPS or LP files and call GLPK[1], COIN CLP/SBB[2], CPLEX[3] and XPRESS[4] to solve linear problems. PuLP provides a nice syntax for the creation of linear problems, and a simple way to call the solvers to perform the optimization. See the example below. This version adds C modules to use the GLPK, COIN and CPLEX solvers without using intermediate MPS or LP files. It is faster and more reliable. You can get it at: http://www.jeannot.org/~js/code/pulp-1.1.tgz The latest version is always available at: http://www.jeannot.org/~js/code/index.en.html Multiple examples are provided. Thanks, Jean-Sebastien References: [1] http://www.gnu.org/software/glpk/glpk.html [2] http://www.coin-or.org/ [3] http://www.cplex.com/ [4] http://www.dashoptimization.com/ Example script: from pulp import * prob = LpProblem("test1", LpMinimize) # Variables x = LpVariable("x", 0, 4) y = LpVariable("y", -1, 1) z = LpVariable("z", 0) # Objective prob += x + 4*y + 9*z # Constraints prob += x+y <= 5 prob += x+z >= 10 prob += -y+z == 7 GLPK().solve(prob) # Solution for v in prob.variables(): print v.name, "=", v.varValue print "objective=", value(prob.objective)

Europython update
by jacob＠cd.chalmers.se May 5, 2005

May 5, 2005

This is a news update about the Europython 2005 conference, to be held in Göteborg, Sweden 27-29 June - Due to some technical prolems with the registration website we have decided to extend the registration of talks until 8 May. We already have an impressive array of talks, but we do have room for some more. We are especially interested in talks focusing on the Python language and talks on Python usage in Science. - To encourage companies to bring their whole staff and their customers to Europython, we have created a corporate discount. If you bring 5 people or more from a single organisation, you get a 20% discount on the regular and early-bird regular fee. - A list of all the accepted talks will be published 11 May 2005 on the Europython website. - Early bird registrations end 15 May. Registration for the low cost accomodation close to the conference venue ends on the same day. For all conference details, go to: http://www.europython.org See you in Göteborg. EuroPython Team About EuroPython: Europython is an annual conference for the Python and Zope communities. It circulates between different sites in Europe. Having started in Charleroi, Belgium, it is now in Göteborg, Sweden and will move to CERN in Swizerland next year. Europython is a community conference run by volunteers. --

Spyce 2.0 beta
by Jonathan Ellis May 4, 2005

May 4, 2005

The beta of Spyce 2.0 is available at http://spyce.sourceforge.net/docs/get.html. Spyce is a python web application server, combining the features of popular frameworks such as JSP and ASP.NET with Pythonic elegance. Spyce may be deployed as a standalone server (or proxied behind Apache), or under mod_python, FastCGI, or CGI. Documentation and demos are at http://spyce.sourceforge.net/. Highlights of Spyce 2.0 include: Active Handlers - reusable components without the leaky abstractions seen in ASP.NET et al. - http://spyce.sourceforge.net/docs/doc-lang_handlers.html Active Tag compiler - http://spyce.sourceforge.net/docs/doc-tag_new2.html OpenACS-like (Tiles-ish, for you JSP people) parent/child templating system - roughly the same speed as include.spyce, so using one parent template has about 1/2 the overhead as the old standard two-includes-for-header-and-footer. - http://spyce.sourceforge.net/docs/doc-tag_core.html#parent Full changelog at http://svn-hosting.com/svn/spyce/trunk/spyce/CHANGES. -Jonathan

ANN: CherryPy-2.0-final released
by remi＠cherrypy.org May 4, 2005

May 4, 2005

Hello everyone, I am happy to announce the first stable release of CherryPy-2. CherryPy-2 is a pythonic, object-oriented web development framework. CherryPy-2 is a redesign of CherryPy-1 (the unpythonic features have been removed): no more compilation step, pure python source code (no more "CherryClass"). Here is a sample Hello, World in CherryPy-2: # from cherrypy import cpg # class HelloWorld: # @cpg.expose # def index(self): # return "Hello world!" # cpg.root = HelloWorld() # cpg.server.start() Main properties: - this code starts a multi-threaded HTTP server that dispatches requests to methods - requests like "http://domain/dir/page?arg1=val1&arg2=val2" are mapped to "dir.page(arg1='val1', arg2='val2')" - CherryPy also supports "positional" arguments in URLs like http://domain/book/science/9 - requests are mapped to an object tree that is "mounted" on cpg.root (for instance: "cpg.root.user", "cpg.root.user.remi", ...) - method must be explicitely exposed with a decorator "@cpg.expose" (or "index.exposed = True" for Python-2.3) - methods can return a generator instead of a string (useful when generating big pages) Here is a non-exhaustive list of CherryPy-2 features: multi-threaded HTTP server, XML-RPC server, sessions, form handling, authentication, unicode support, gzip-compression, virtual hosting, WSGI adapter The design of CherryPy-2 allows to easily write/use pluggable "filters" or "modules": - filters perform operations on the request/response such as gzip-compression or string encoding - modules are web applications (like a blog or a web forum) than can be easily "mounted" anywhere you want in your website CherryPy-2 is already used in production by many sites and is supported by an active community. Remi. http://www.cherrypy.org
