Call for Papers: Workshop on Self-sustaining Systems (S3) 2010
by Carl Friedrich Bolz 13 May '10

13 May '10

*** Workshop on Self-sustaining Systems (S3) 2010 *** September 27-28, 2010 The University of Tokyo, Japan http://www.hpi.uni-potsdam.de/swa/s3/s3-10/ In cooperation with ACM SIGPLAN === Call for papers === The Workshop on Self-sustaining Systems (S3) is a forum for discussion of topics relating to computer systems and languages that are able to bootstrap, implement, modify, and maintain themselves. One property of these systems is that their implementation is based on small but powerful abstractions; examples include (amongst others) Squeak/Smalltalk, COLA, Klein/Self, PyPy/Python, Rubinius/Ruby, and Lisp. Such systems are the engines of their own replacement, giving researchers and developers great power to experiment with, and explore future directions from within, their own small language kernels. S3 will be take place September 27-28, 2010 at The University of Tokyo, Japan. It is an exciting opportunity for researchers and practitioners interested in self-sustaining systems to meet and share their knowledge, experience, and ideas for future research and development. --- Submissions and proceedings --- S3 invites submissions of high-quality papers reporting original research, or describing innovative contributions to, or experience with, self-sustaining systems, their implementation, and their application. Papers that depart significantly from established ideas and practices are particularly welcome. Submissions must not have been published previously and must not be under review for any another refereed event or publication. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Revised papers will be published as post-proceedings in the ACM Digital Library. Papers should be submitted electronically via EasyChair at http://www.easychair.org/conferences/?conf=s32010 in PDF format. Submissions must be written in English (the official language of the workshop) and must not exceed 10 pages. They should use the ACM SIGPLAN 10 point format, templates for which are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. --- Venue --- The University of Tokyo, Komaba Campus, Japan --- Important dates --- Submission of papers: July 30, 2010 Author notification: August 27, 2010 Early registration: September 3, 2010 Revised papers: September 10, 2010 S3 workshop: September 27-28, 2010 Final papers for ACM-DL post-proceedings: October 15, 2010 --- Chairs --- Robert Hirschfeld (Hasso-Plattner-Institut Potsdam, Germany) hirschfeld(a)hpi.uni-potsdam.de Hidehiko Masuhara (The University of Tokyo, Japan) masuhara(a)graco.c.u-tokyo.ac.jp Kim Rose (Viewpoints Research Institute, USA) kim.rose(a)vpri.org --- Program committee --- Carl Friedrich Bolz, University of Duesseldorf, Germany Johan Brichau, Universite Catholique de Louvain, Belgium Shigeru Chiba, Tokyo Institute of Technology, Japan Brian Demsky, University of California, Irvine, USA Marcus Denker, INRIA Lille, France Richard P.

ANN: Release of SimPy2.1.0beta (Simulation in Python)
by Klaus G. Muller 12 May '10

12 May '10

It is my pleasure to announce the release of SimPy 2.1.0beta. It is ready for download at https://sourceforge.net/projects/simpy/. It is published for community testing. SimPy 2.1.0 is a major new version, with a refactored code base, two powerful API additions, additional documentation and bug fixes. 2.1.0 is fully backward compatible with 2.0.1 and earlier versions. Do not use this release for production purposes yet, but help with testing it. Submit any bugs/comments/suggestions to the SimPy user mailing list (simpy-users(a)lists.sourceforge.net). What is SimPy? ~~~~~~~~~~~~~~ SimPy (= Simulation in Python) is a process-based discrete-event simulation package based on an implemented in standard Python. It is released under the GNU LGPL. It provides the modeller with components of a simulation model. These include processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics. SimPy has plotting and GUI capabilities "out of the box". It comes with extensive documentation, tutorials and a large number of example models. Dependencies ~~~~~~~~~~~~ SimPy 2.1.0 works with Python 2.3 and later versions. It does not work with Python 3.x. SimPy also works with Jython and IronPython, with the exception of SimPy's plotting and GUI capabilities. Change notes ============ Here are the changes to the previous SimPy release (2.0.1): Additions ~~~~~~~~~ - A function `step` has been added to the API. When called, it executes the next scheduled event. (`step` is actually a method of Simulation.) - Another new function is `peek`. It returns the time of the next event. By using `peek` and `step` together, one can easily write e.g. an interactive program to step through a simulation event by event. - A simple interactive debugger ``stepping.py`` has been added. It allows stepping through a simulation under user control, viewing the event list, skipping to a process' next event, etc.. - Versions of the Bank tutorials using the advanced object-oriented API have been added. - A new document describes tools for gaining insight into and debugging SimPy models. Changes ~~~~~~~ - Major re-structuring of SimPy code, resulting in much less SimPy code -- great for the maintainers. - Checks have been added which test whether entities belong to the same `Simulation` instance. - The `Monitor` and `Tally` methods `timeAverage` and `timeVariance` now calculate only with the observed time-series. - Changed class `Lister` so that circular references between objects no longer lead to stack overflow and crash. Bug repairs ~~~~~~~~~~~ - Functions ``allEventNotices`` and ``allEventTimes`` are working again. - Error messages for methods in SimPy.Lib work again. Acknowledgements =============== The great code refactoring was done by Ontje Lünsdorf, with key inputs from Stefan Scherfke. Thanks, guys! I also thank the other developers and users for their inputs and support in defining SimPy 2.1.0. Now, go ahead, download SimPy 2.1.0beta, and then test it. (Did you know that you can easily create an isolated Python environment with virtualenv { http://pypi.python.org/pypi/virtualenv }? Use that, and you don't have to overwrite your current SimPy installation for testing 2.1.0. Also good if you are new to SimPy and just want to try it out.) Klaus Müller

Version 0.3.9 of the Python config module has been released.
by Vinay Sajip 11 May '10

11 May '10

Version 0.3.9 of the Python config module has been released. What Does It Do? ================ The config module allows you to implement a hierarchical configuration scheme with support for mappings and sequences, cross-references between one part of the configuration and another, the ability to flexibly access real Python objects, facilities for configurations to include and cross-reference one another, simple expression evaluation and the ability to change, save, cascade and merge configurations. You can easily integrate with command line options using optparse. This module has been developed on python 2.3 but should work on version 2.2 or greater. A test suite using unittest is included in the distribution. A very simple configuration file (simple.cfg): # starts here message: Hello, world! #ends here a very simple program to use it: from config import Config cfg = Config(file('simple.cfg')) print cfg.message results in: Hello, world! Configuration files are key-value pairs, but the values can be containers that contain further values. A simple example - with the example configuration file: messages: [ { stream : `sys.stderr` message: 'Welcome' name: 'Harry' } { stream : `sys.stdout` message: 'Welkom' name: 'Ruud' } { stream : $messages[0].stream message: 'Bienvenue' name: Yves } ] a program to read the configuration would be: from config import Config f = file('simple.cfg') cfg = Config(f) for m in cfg.messages: s = '%s, %s' % (m.message, m.name) try: print >> m.stream, s except IOError, e: print e which, when run, would yield the console output: Welcome, Harry Welkom, Ruud Bienvenue, Yves The above example just scratches the surface. There's more information about this module available at http://www.red-dove.com/config-doc/ Comprehensive API documentation is available at http://www.red-dove.com/config/index.html As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last release posted on comp.lang.python[.announce]: ===================================================== Fix bug in parsing numbers with exponents (reported by Philip Søeberg).

[ANN] pylint 0.21 / astng 0.20.1
by Sylvain Thénault 11 May '10

11 May '10

Hi there! I'm pleased to announce a new pylint / astng release. It provides several bug fixes, as well as command line enhancements: all options for messages / reports control have been merged into two generic --enable / --disable option. Also, pylint --help is much more concise, and longer version is available through the --long-help option. Notice that because of that, this release introduce backward incompatible changes in the command line, you may have to update your scripts. Last but not least, the gui has been revisited by students from the Toronto university, that should please windows users! More details about changes in packages'ChangeLog. What is pylint ? ---------------- Pylint is a python tool that checks if a module satisfy a coding standard. Pylint can be seen as another pychecker since nearly all tests you can do with pychecker can also be done with Pylint. But Pylint offers some more features, like checking line-code's length, checking if variable names are well-formed according to your coding standard, or checking if declared interfaces are truly implemented, and much more (see http://www.logilab.org/projects/pylint/ for the complete check list). The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature. The usage it quite simple : $ pylint mypackage.mymodule This command will output all the errors and warnings related to the tested code (here : mypackage.mymodule), will dump a little summary at the end, and will give a mark to the tested code. Pylint is free software distributed under the GNU Public Licence.
