ANN: SciPy 2006 Conference
by Travis N. Vaught April 11, 2006

April 11, 2006

Greetings, The *SciPy 2006 Conference* is scheduled for August 17-18, 2006 at CalTech. A tremendous amount of work has gone into SciPy and Numpy over the past few months, and the scientific python community around these and other tools has truly flourished[1]. The Scipy 2006 Conference is an excellent opportunity to exchange ideas, learn techniques, contribute code and affect the direction of scientific computing with Python. Conference details are at http://www.scipy.org/SciPy2006 Keynote ------- Python language author Guido van Rossum (!) has agreed to be the Keynote speaker at this year's Conference. http://www.python.org/~guido/ Registration: ------------- Registration is now open. You may register early online for $100.00 at http://www.enthought.com/scipy06. Registration includes breakfast and lunch Thursday & Friday and a very nice dinner Thursday night. After July 14, 2006, registration will cost $150.00. Call for Presenters ------------------- If you are interested in presenting at the conference, you may submit an abstract in Plain Text, PDF or MS Word formats to abstracts(a)scipy.org -- the deadline for abstract submission is July 7, 2006. Papers and/or presentation slides are acceptable and are due by August 4, 2006. Tutorial Sessions ----------------- Several people have expressed interest in attending a tutorial session. The Wednesday before the conference might be a good day for this. Please email the list if you have particular topics that you are interested in. Here's a preliminary list: - Migrating from Numeric or Numarray to Numpy - 2D Visualization with Python - 3D Visualization with Python - Introduction to Scientific Computing with Python - Building Scientific Simulation Applications - Traits/TraitsUI Please rate these and add others in a subsequent thread to the SciPy-user mailing list. Perhaps we can pick 4-6 top ideas and recruit speakers as demand dictates. The authoritative list will be tracked here: http://www.scipy.org/SciPy2006/TutorialSessions Coding Sprints -------------- If anyone would like to arrive earlier (Monday and Tuesday the 14th and 15th of August), we can borrow a room on the CalTech campus to sit and code against particular libraries or apps of interest. Please register your interest in these coding sprints on the SciPy-user mailing list as well. The authoritative list will be tracked here: http://www.scipy.org/SciPy2006/CodingSprints Mailing list address: scipy-user(a)scipy.org Mailing list archives: http://dir.gmane.org/gmane.comp.python.scientific.user Mailing list signup: http://www.scipy.net/mailman/listinfo/scipy-user [1] Some stats: NumPy has averaged over 16,000 downloads per month Sept. 05 to March 06. SciPy has averaged over 3,800 downloads per month in Feb. and March 06. (both scipy and numpy figures do not include the 2000 instances per month downloaded as part of the Python Enthought Edition Distribution for Windows.)

ANN: QWeb, a python framework to build web applications quickly
by Antony Lesuisse April 11, 2006

April 11, 2006

Can you imagine a day without a new python web framework ? QWeb is Yet an another web framework (WSGI compatible). This one is in the spirit of web.py (http://webpy.org/) URL: http://antony.lesuisse.org/qweb/trac/ It provides: * A lightweight request handler (QWebRequest) * An xml templating engine (QWebXml and QWebHtml) * A simple name based controler (qweb_control) * A standalone WSGI Server (QWebWSGIServer) * A cgi and fastcgi WSGI wrapper (taken from flup) * A startup function that starts cgi, factgi or standalone according to the evironement (qweb_autorun). The templating system (that can be used independently) is IMHO superior to everything else. It looks like kid or ZPT. It takes pure XML to generate any kind of textual output (valid or non valid xml). It's very simple and extensible. QWebHtml is an extension of the basic templates that support urls and forms. The example blog shows how to use the templates: http://antony.lesuisse.org/qweb/files/QWeb-0.5-blog.tar.gz It's a small blog engine with comments made of 2 files. It uses sqlobject and sqlite as backend. blog.py 131 lines long (model and controller) template.xml 380 lines long (views 6 templates) The demo example illustrate the use of the request object and static component: http://antony.lesuisse.org/qweb/files/QWeb-0.5-demo.tar.gz Helloworld ---------- import qweb def helloapp(environ, start_response): req = qweb.QWebRequest(environ, start_response) req.response_headers['Content-type'] = 'text/plain' req.write('Hello World') return req if __name__ == '__main__': qweb.qweb_wsgi_autorun(helloapp) Example template: ----------------- <t t-name="democall"> democall called, <br/> <t t-esc="0"/> <br/> <t t-esc="arg1"/> <br/> <t t-esc="arg2"/> <br/> </t> <t t-name="demo_template"> <h2>The QWebXml and QWebHTML templating system</h2> <pre> Basic tags: t-raw t-esc t-if t-foreach t-call t-set t-trim </pre> <a t-att-class="varname">test</a> <t t-raw="varname"/> <t t-esc="varname"/> <t t-if="1==2">KO</t> <t t-if="1!=2">OK</t> <t t-call="democall"> <t t-set="arg1">the value of arg1</t> <t t-set="arg2" t-eval="2+2"/> body of the call </t> <t t-foreach="range(10)" t-as="i"> i= <t t-esc="i"/><br/> </t> </t> Usage of template: ------------------ import qweb t=qweb.QWebHtml('file.xml') t.render("demo_template",{'varname':"some text with a tag <tag>"})

ANNOUNCE: PyGObject 2.10.1
by Johan Dahlin April 11, 2006

April 11, 2006

I am pleased to announce version 2.10.1 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygobject/pygobject-2.10.1.tar.gz What's new since PyGObject 2.10.0: - uint64 property bug fix (Andy Wingo) - Hard code path to 2.0 (Gustavo) - Allow only tuples and lists in strv to value (Gustavo) - Include dsextras.py in the dist (Johan) Blurb: GObject is a object system library used by GTK+ and GStreamer. PyGObject provides a convenient wrapper for the GObject+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyGTK, PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject requires GObject >= 2.8.0 and Python >= 2.3.5 to build. Bug reports, as always, should go to Bugzilla; check out http://www.pygtk.org/developer.html and http://www.pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK.
