ANN: Yappi(Yet Another Python Profiler) 0.51 released
by Sumer Cip 15 May '10

15 May '10

Hi all, Yappi (Yet Another Python Profiler) 0.51 released. See the version highlights: * OPTIMIZATION:Use per-pit cpc for better accuracy in different timing_sample values. Now timing_sample is not linearly decreasing the timing accuracy for most of the applications tested. We reduced the runtime of the profiler from 3.2 secs to 0.7 by giving away ~%2 timing accuracy. This means yappi can now run 4x-7x times faster than the standart cProfile by increasing timing_sample values with very little accuracy defect. * Python 2.6.5 gives import yappi Dll load failed error. This is due to VC2008 compile. Unfortunately, we need to use VC Express Mingw is not working because of MSVCR dll files on 2.6.5 on some machines. * Use snprintf for stat handling code. There may be some buffer overflow situations. Use PyOS_snprintf for platform differences. (Thanks to Dave Peticolas) * Format stat STRINGs from left, instead of right. (Thanks to Dave Peticolas) * OPTIMIZATION:Move ctx calculation code to callback function. Optimize call_XXX functions as much as possible. * Move timing calculation code from header to the C file. * MACRO defining code in setup.py is broken for some compilers, use DEFINE_MACRO keyword. * OPTIMIZATION:Disable HASH table linked list swapping code, it is not adapting to the profiler nature very well. Rollback to simple hash- table-bucketing. See below for more and download: http://code.google.com/p/yappi/ Thanks, twitter.com/sumercip

ANN: MDP release 2.6 and MDP Sprint 2010
by Tiziano Zito 14 May '10

14 May '10

We are glad to announce release 2.6 of the Modular toolkit for Data Processing (MDP). MDP is a Python library of widely used data processing algorithms that can be combined according to a pipeline analogy to build more complex data processing software. The base of available algorithms includes, to name but the most common, Principal Component Analysis (PCA and NIPALS), several Independent Component Analysis algorithms (CuBICA, FastICA, TDSEP, JADE, and XSFA), Slow Feature Analysis, Restricted Boltzmann Machine, and Locally Linear Embedding. What's new in version 2.6? -------------------------- - Several new classifier nodes have been added. - A new node extension mechanism makes it possible to dynamically add methods or attributes for specific features to node classes, enabling aspect-oriented programming in MDP. Several MDP features (like parallelization) are now based on this mechanism, and users can add their own custom node extensions. - BiMDP is a large new package in MDP that introduces bidirectional data flows to MDP, including backpropagation and even loops. BiMDP also enables the transportation of additional data in flows via messages. - BiMDP includes a new flow inspection tool, that runs as as a graphical debugger in the webrowser to step through complex flows. It can be extended by users for the analysis and visualization of intermediate data. - As usual, tons of bug fixes The new additions in the library have been thoroughly tested but, as usual after a public release, we especially welcome user's feedback and bug reports. MDP Sprint 2010 --------------- Following our tradition of sprint-driven development, the team of the core developers decided to organize a programming sprint open to external participants. We invite in particular all users who implemented new algorithms and would like to see them integrated in MDP: you will work together with a core developer!

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 12 May '10

12 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.

[ANN] PythonQt 2.0 released
by Florian Link 09 May '10

09 May '10

Embedding Python into your Qt / C++ application and accessing the whole Qt API from within your Python scripts is right at your hands with the new PythonQt 2.0 release. http://pythonqt.sourceforge.net/ PythonQt consists of a small dynamic library that offers scripting QObjects and interaction between Qt and Python in both directions, mostly in the spirit of QtScript, but for Python. In addition to that, the core library can be extended using the new wrapper generator to support raw C++ classes. PythonQt comes with pregenerated wrappers for most Qt modules. Note: The focus of PythonQt is embedding Python into your existing Qt application (to make some aspects of it scriptable), and not to create the whole application in Python. If you are looking for that, go for PyQt or PySide! The main features of this update are: - a new wrapper generator (based on the qtscript generator) that generates Python wrappers for (almost) the complete Qt framework - support for multiple inheritance of wrapped C++ classes - support for polymorphic downcast (e.g., QEvent will get its derived type based on the type id) - dynamic property support (both setting and getting via normal python attributes) - public member variable wrapping (for QStyleOptions and derived classes) - full support for operators (so that QPoint, QSize etc. can be used with operators in Python) - automatic casting for special classes (QPen/QBrush/GlobalColor enum/...) - deriving C++ objects from Python to implement virtual functions (experimental feature) With this release, the feature set of PythonQt comes much closer to what PyQt and PySide offer, it is now possible to create complex GUIs using PythonQt and you could delegate large parts of your C++ application to Python scripting (e.g., to let users customize the GUI, to support Python plugins in your application, your idea goes here...). regards, Florian

Pydev 1.5.7 Released
by Fabio Zadrozny 07 May '10

07 May '10

Hi All, Pydev 1.5.7 has been released Details on Pydev: http://pydev.org Details on its development: http://pydev.blogspot.com Release Highlights: ------------------------------- * **Uniquely identifying editors:** * Names are never duplicated * Special treatment for __init__ * Special treatment for django on views, models and tests * See: http://pydev.blogspot.com/2010/04/identifying-your-editors.html for details * **Debugger:** * **CRITICAL**: Fixed issue which could make the debugger skip breakpoints * Properly dealing with varibles that have '<' or '>' * Debugging file in python 3 with an encoding works * Double-clicking breakpoint opens file from the workspace instead of always forcing an external file * Added '* any file' option for file selection during a debug where the file is not found * **Performance improvements for dealing with really large files:** * Code folding marks won't be shown on *really large files* for performance reasons * Performance improvements in the code-analysis (much faster for *really large files*) * Outline tree is also faster * **Interpreter configuration:** * Only restoring the needed interpreter info (so, it's much faster to add a new interpreter) * Using an asynchronous progress monitor (which makes it even faster) * Interpreter location may not be duplicated (for cases where the same interpreter is used with a different config, virtualenv should be used) * Properly refreshing internal caches (which made a ctrl+2+kill or a restart of eclipse needed sometimes after configuring the interpreter) * socket added to forced builtins * **Python 3 grammar:** * Code completion and code-analysis work when dealing with keyword only parameters * Properly reporting syntax error instead of throwing a NumberFormatException on "1.0L" * **Editor and forcing tabs:** * Option to toggle forcing tabs added to the editor context menu * Fixed tabs issue which could change the global setting on force tabs * **Indentation:** * Added rule so that indentation stops at the level of the next line def or @ (to indent to add a decorator) * Auto indent strategy may indent based on next line if the previous is empty * **General:** * Django configuration supporting version 1.2 (contribution by Kenneth Belitzky) * Fixed encoding problem when pasting encoded text with indentation * asthelper.completions no longer created on current directory when project is removed * __all__ semantics correct when a tuple is defined (and not only when a list is defined) * Fixed issue in extract method (was not creating tuple on caller function with multiple returns) * Improved heuristic for assist assign (ctrl+1) * On search open files (ctrl+2+s), dialog is opened if nothing is entered and there's no editor selection * Fixed issue where ctrl+2 would not work on linux What is PyDev? --------------------------- PyDev is a plugin that enables users to use Eclipse for Python, Jython and IronPython development -- making Eclipse a first class Python IDE -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, refactor, debug and many others.

Hello! Things are moving quickly in preparation for SciPy 2010: Last week we announced the General Conference schedule (http://conference.scipy.org/scipy2010/schedule.html ), Tuesday we announced our student sponsorship recipients (http://conference.scipy.org/scipy2010/student.html ) and now we're ready to tell you give you a look at the talks we have lined up for our Bioinformatics and Parallel Processing /Cloud Computing tracks. ===Parallel Processing & Cloud Computing track=== We really appreciate Brian and Ken's work organizing the papers for this specialized track. And of course, thanks to everyone who submitted a paper. There has been a great deal of interest in this set of talks — and word on the street is that Brian may even have a HPC tutorial up his sleeve... * StarCluster - NumPy/SciPy Computing in the Cloud- Justin Riley * pomsets: workflow management for your cloud- Michael J Pan * Getting Down with Big Data Jared Flatow, Anita Lillie, Ville Tuulos * StarFlow: A Cloud-Enables Python Workflow Engine for Scientific Analysis Pipelines Elaine Angelino, Dan Yamins, Margo Seltzer * A Programmatic Interface for Particle Plasma Simulation in Python, and Early Backend Results with PyCUDA Min Ragan-Kelley * Parallel Computing with IPython: an Application to Air Pollution Modeling B.E. Granger, J.G. Hemann * Astronomy App in the Cloud using Google Geo APIs and Python App Engine Shawn Shen ===Bioinformatics track=== Once again, we are indebted to Glen Otero, from Dell, for putting together the Bioinformatics track. He received some fantastic papers and we're really looking forward to these presentations: * Protein Folding with Python on Supercomputers Jan H. Meinke * Can Python Save Next-Generation Sequencing? * The Use of Galaxy for the Research and the Teaching of Genomics Roy Weckiewicz, Jim Hu, and Rodolfo Aramayo ===Early registration ends next Monday=== That's right: Only a few days left before rates increase! Think of all the BBQ and breakfast tacos you can buy with that $50-$100 you'll save by registering early. If that doesn't convince you, consider: -Cheap flights to Austin- Buy your tickets now for some very nice prices: $275 from Chicago, $330 from San Francisco, $380 from New York City, $810 from London...(prices from Kayak.com) -Convenient & affordable hotel- We got an fantastic deal for on-site accommodations at the AT&T Conference Center. Pay only $89/night for single occupancy or $105/ night for double occupancy. It will be great to have everyone staying in the same spot. Once you register, you'll get a code to book your hotel reservation. The discounted rate will be applied automatically. https://conference.scipy.org/scipy2010/accommodation.html No car necessary to get to the conference... and see Austin! An airport bus (http://capmetro.org/riding/current_schedules/maps/rt100_sb.pdf ) runs straight to and from the AT&T center, so you won't have to rent a car at all. Plus, the UT campus area is in walking distance to a number of great restaurants and activities. For any longer trips you'd like to make Austin has a great public bus system. Not to mention all of the mind-blowing things you'll learn and outstanding people you'll meet and catch up with. So what are you waiting for?

pytest-xdist 1.2: distributed testing getting stable
by holger krekel 06 May '10

06 May '10

pytest-xdist 1.2 brings bug fixes and improved stability for distributed testing with py.test. This plugin allows to ad-hoc distribute test runs to multiple CPUs, different Python interpreters or remote machines. It requires setuptools or distribute which help to pull in the neccessary execnet and pytest-core dependencies. See here for extensive docs: http://pytest.org/plugin/xdist.html best, holger 1.2 ------------------------- - fix issue79: sessionfinish/teardown hooks are now called systematically on the slave side - introduce a new data input/output mechanism to allow the master side to send and receive data from a slave. - fix race condition in underlying pickling/unpickling handling - use and require new register hooks facility of py.test>=1.3.0 - require improved execnet>=1.0.6 because of various race conditions that can arise in xdist testing modes. - fix some python3 related pickling related race conditions - fix PyPI description
