ANN: pystuck - or what to do when python gets stuck?
by Alon Horev Dec. 16, 2011

Dec. 16, 2011

pystuck.py is a utility for analyzing stuck python programs (or just hardcore debugging). pystuck currently has two major features: 1. print all running threads' stack traces. (good for finding a long- lasting/blocking function) 2. remote inspection of modules and variables without interrupting the program. (finding deadlocks and such) more examples, usage and installation notes can be found here: https://github.com/alonho/pystuck

pytest-2.2.1: bug fixes, better teardowns
by holger krekel Dec. 16, 2011

Dec. 16, 2011

pytest-2.2.1: bug fixes, better teardowns =========================================================================== pytest-2.2.1 is a minor backward-compatible release of the the py.test testing tool. It contains bug fixes and little improvements, including documentation fixes. If you are using the distributed testing plugin make sure to upgrade it to pytest-xdist-1.8. For general information see here: http://pytest.org/ To install or upgrade pytest: pip install -U pytest # or easy_install -U pytest Special thanks for helping on this release to Ronny Pfannschmidt, Jurko Gospodnetic and Ralf Schmitt. best, holger krekel Changes between 2.2.0 and 2.2.1 ---------------------------------------- - fix issue99 (in pytest and py) internallerrors with resultlog now produce better output - fixed by normalizing pytest_internalerror input arguments. - fix issue97 / traceback issues (in pytest and py) improve traceback output in conjunction with jinja2 and cython which hack tracebacks - fix issue93 (in pytest and pytest-xdist) avoid "delayed teardowns": the final test in a test node will now run its teardown directly instead of waiting for the end of the session. Thanks Dave Hunt for the good reporting and feedback. The pytest_runtest_protocol as well as the pytest_runtest_teardown hooks now have "nextitem" available which will be None indicating the end of the test run. - fix collection crash due to unknown-source collected items, thanks to Ralf Schmitt (fixed by depending on a more recent pylib)

HTSQL 2.1-RC1 : A Query Language for the Accidental Programmer
by Clark C. Evans Dec. 16, 2011

Dec. 16, 2011

We'd like to announce the release candidate for HTSQL 2.1, a high-level query language and web service gateway for relational databases. HTSQL is specifically designed for analytical inquiries and targeted to data analysts and web developers. HTSQL is implemented as a WSGI component, works with PostgreSQL, MySQL, SQLite and could be used to embed ad-hoc reporting features into your Python application. Homepage: http://htsql.org Download: http://pypi.python.org/pypi/HTSQL/ Source: http://bitbucket.org/prometheus/htsql Since 2.0 release, announced in February, we added many new language features which increase the "query power" of the language. HTSQL is now able to express quite sophisticated business inquiries. The 2.2 release of HTSQL later this year will be focused on "usability". It'll include improved configuration, a query editor and formatting options. Also for this release we've cleaned up the homepage for HTRAF -- a javascript toolkit for constructing attractive dashboards and interactive reports. This toolkit is MIT licensed and implemented as a JQuery plugin. For more detail, please visit http://htraf.org. Let's us know if you have any questions! Clark C. Evans & Kirill Simonov *********************************************************** HTSQL -- A Query Language for the Accidental Programmer *********************************************************** HTSQL ("Hyper Text Structured Query Language") is a high-level query language for relational databases. The target audience for HTSQL is the accidental programmer -- one who is not a SQL expert, yet needs a usable, comprehensive query tool for data access and reporting. HTSQL is also a web service which takes a request via HTTP, translates it into a SQL query, executes the query against a relational database, and returns the results in a format requested by the user agent (JSON, CSV, HTML, etc.). Use of HTSQL with open source databases (PostgreSQL, MySQL, SQLite) is royalty free under BSD-style conditions. Use of HTSQL with proprietary database systems (Oracle, Microsoft SQL) requires a commercial license. See ``LICENSE`` for details. For installation instructions, see ``INSTALL``. For list of new features in this release, see ``NEWS``. HTSQL documentation is in the ``doc`` directory. http://htsql.org/ The HTSQL homepage http://htsql.org/doc/introduction.html Get taste of HTSQL http://htsql.org/doc/tutorial.html The HTSQL tutorial http://bitbucket.org/prometheus/htsql HTSQL source code irc://irc.freenode.net#htsql IRC chat in #htsql on freenode http://lists.htsql.org/mailman/listinfo/htsql-users The mailing list for users of HTSQL HTSQL is copyright by Prometheus Research, LLC. HTSQL is written by Clark C. Evans <cce(a)clarkevans.com> and Kirill Simonov <xi(a)resolvent.net>. Generous support for HTSQL was provided by the Simons Foundation. This material is also based upon work supported by the National Science Foundation under Grant #0944460.

Ann: OpenOpt and FuncDesigner 0.37
by dmitrey Dec. 15, 2011

Dec. 15, 2011

Hi all, I'm glad to inform you about new release 0.37 (2011-Dec-15) of our free software: OpenOpt (numerical optimization): IPOPT initialization time gap (time till first iteration) for FuncDesigner models has been decreased Some improvements and bugfixes for interalg, especially for "search all SNLE solutions" mode (Systems of Non Linear Equations) Eigenvalue problems (EIG) (in both OpenOpt and FuncDesigner) Equality constraints for GLP (global) solver de Some changes for goldenSection ftol stop criterion GUI func "manage" - now button "Enough" works in Python3, but "Run/ Pause" not yet (probably something with threading and it will be fixed in Python instead) FuncDesigner: Major sparse Automatic differentiation improvements for badly- vectorized or unvectorized problems with lots of constraints (except of box bounds); some problems now work many times or orders faster (of course not faster than vectorized problems with insufficient number of variable arrays). It is recommended to retest your large-scale problems with useSparse = 'auto' | True| False Two new methods for splines to check their quality: plot and residual Solving ODE dy/dt = f(t) with specifiable accuracy by interalg Speedup for solving 1-dimensional IP by interalg SpaceFuncs and DerApproximator: Some code cleanup You may trace OpenOpt development information in our recently created entries in Twitter and Facebook, see http://openopt.org for details.
