ANN: SimPy (Simulation in Python) 2.0.1 release
by Klaus Müller 08 Apr '09

08 Apr '09

We are happy to announce the release of SimPy 2.0.1, a bug-fix release of version 2.0. Download from: https://sourceforge.net/project/showfiles.php?group_id=62366&release_id=674… Your feedback (errors found, proposals for changes, etc.) is requested, using the SimPy Users Mailing List (simpy-users {at}lists.sourceforge.net). SimPy 2.0.1 requires Python 2.3 or later. It does not yet run under Python 3. The release of a SimPy version for Python 3 is planned for later in 2009, depending on the development progress of Python 3. What is SimPy? ------------------------ SimPy is a process-based discrete-event simulation language based on standard Python and 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 comes with extensive documentation, tutorials and many example models. SimPy provides plotting and a GUI capability "out of the box". What is new in SimPy 2.0.1? ------------------------------------------- Bug fixes ========== - Repaired a number of coding errors in several models in the SimPyModels folder. - Repaired SimulationRT.py bug introduced by recoding for the OO API. - Repaired errors in sample programs in documents: * Simulation with SimPy - In Depth Manual * SimPy's Object Oriented API Manual * Simulation With Real Time Synchronization Manual * SimPlot Manual * Publication-quality Plot Production With Matplotlib Manual Additions ============ - Tests for real time behavior (testRT_Behavior.py and testRT_Behavior_OO.py in folder SimPy). Acknowledgements ---------------------------- The development of SimPy 2.0.1 has benefitted tremendously from the excellent, extensive contributions by Fabrice Benichou. Thanks, Fabrice! You have been a great editor! Keep working with us! The many other contributions of the SimPy user and developer communities are of course also gratefully acknowledged. Download, test, enjoy and give us feedback! Happy SimPying! Klaus Muller Tony Vignaux

[ANN] scikits.timeseries 0.91.0
by matt knox 08 Apr '09

08 Apr '09

We are pleased to announce the release of scikits.timeseries 0.91.0 This is the first official public release of the scikits.timeseries module. Due to the long birthing period, the api is considered stable and the version number was chosen to reflect the relative maturity of the initial release compared to a typical first release. Home page: http://pytseries.sourceforge.net/ Please see the website for installation requirements and download details. Note that the recently released numpy 1.3.0 is a strict requirement. Windows binaries are provided for Python 2.5 and 2.6. About the package ================= The scikits.timeseries module provides classes and functions for manipulating, reporting, and plotting time series of various frequencies. The focus is on convenient data access and manipulation while leveraging the existing mathematical functionality in numpy and scipy. If the following scenarios sound familiar to you, then you will likely find the scikits.timeseries module useful: * Compare many time series with different ranges of data (eg. stock prices); * Create time series plots with intelligently spaced axis labels; * Convert a daily time series to monthly by taking the average value during each month; * Work with data that has missing values; * Determine the last business day of the previous month/quarter/year for reporting purposes; * Compute a moving standard deviation efficiently; These are just some of the scenarios that are made very simple with the scikits.timeseries module. Thanks, Matt Knox & Pierre Gerard-Marchant

Myles Braithwaite will be showing us how to work within Google App Engine[1]: Google App Engine is a platform to building and hosting web applications on Google's infrastructure (which is sometimes called PaaS). It has a pay-for-what-you-use payment scheme but anything below 5 million pageviews a month is free[2]. We'll meet at the regular place and time, Linux Caffe[3] on the Third Tuesday of the month (April 21st this month) at ~7, kicking off the festivities at 7:15pm. Details about the Venue on the website[4]. [1] http://code.google.com/appengine/docs/whatisgoogleappengine.html [2] There's also some space limits and other restrictions.
