HTSQL 2.1-RC1 : A Query Language for the Accidental Programmer
by Clark C. Evans 16 Dec '11

16 Dec '11

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.

Bazaar <http://bazaar.canonical.com/> is part of the GNU system <http://gnu.org/> to produce a free operating system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from https://launchpad.net/bzr/2.4/2.4.0 as a source tarball. Installers are available for windows and OSX from the url above too. This release marks the start of another long-term-stable series. From here, we will only make bugfix releases on the 2.4 series (2.4.1, etc, and support it until February 2013), while 2.5 will become our new development series. This is a bugfix and polish release over the 2.3 series, with a large number of bugs fixed (>150 for the 2.4 series alone), and some performance improvements. Support for python 2.4 and 2.5 has been dropped, many large working tree operations have been optimized as well as some stacked branches operations. Users are encouraged to upgrade from the other stable series. See http://doc.bazaar.canonical.com/bzr.dev/en/whats-new/whats-new-in-2.4.html for more details, Vincent

ANN: Enjuewemela 0.4.1
by Facundo Batista 24 Aug '11

24 Aug '11

Enjuewemela is yet another similar game to the popular "Bejeweled" or "Diamond Mine". The game basics is to make alignment of 3 or more gems, both vertically or horizontally by swapping adjacent gems. It's (of course) written in Python, using the cocos2d game framework. Version 0.4.1 brings lots of new features and bugfixes; the highlights are: - New game style! Crazy mode! Try it, you'll like it. - We have a brand new 3.0 web site! Check it out: http://enjuewemela.taniquetil.com.ar/ (it even has a Donations button) - Refactored completely the audio backend: the new one is more portable, faster, and should just make its work without you having to know anything about it - It now installs in the desktop! With this, you can execute the game through the Applications menu The easiest way of installing it, if you have Debian or Ubuntu, is using this installer: http://launchpad.net/enjuewemela/trunk/0.4.1/+download/enjuewemela-0.4.1.deb If you want to automatically get the new updates, you can subscribe to the PPA; open a command line and type: sudo add-apt-repository ppa:facundo/enjuewemela In any other case, you can install it from the tarball: http://launchpad.net/enjuewemela/trunk/0.4.1/+download/enjuewemela-0.4.1.ta… Enjoy it! -- .

ws4py 0.1.2: WebSocket for Python
by Sylvain Hellegouarch 24 Aug '11

24 Aug '11

Hi all, I recently pushed a new version of ws4py, a WebSocket client/server library for Python 2.x. == Overview == ws4py implements version 8 of draft-10 of the WebSocket specification. It supports CherryPy 3.2.1 and gevent as WebSocket servers. Tornado already ships supports for a WebSocket server. Client support comes for Tornado and a a threaded implementation only relying on Python stdlib. It heavily relies on generators using both .next() and .send(bytes) to decouple data provider from the actual WebSocket protocol implementation which makes it quite easy to port to other providers if need be (Kamaelia, circuits come to mind). The servers work fine against a Chrome 15. It hasn't been tested against other browsers. ws4py does run on Android devices via the SL4A package. == Get it == ws4py is a pure Python package and can be installed from PyPI: http://pypi.python.org/pypi/ws4py/0.1.2 Its repository is hosted on github: https://github.com/Lawouach/WebSocket-for-Python == Functional Test results == Some test results, using the Autobahn test suite: http://www.defuze.org/oss/ws4py/testreports/servers/ http://www.tavendo.de/autobahn Those tests show that for large messages, ws4py might not be yet tuned enough. This will be addressed in a near future release. == Examples == A daft in-browser chat example: https://github.com/Lawouach/WebSocket-for-Python/blob/master/example/echo_c… An Android based demo that displays the device sensors in real-time in a HTML5 canvas: https://github.com/Lawouach/WebSocket-for-Python/tree/master/example http://www.defuze.org/oss/ws4py/screenshots/droidsensors.png == Acknowledgments == Jeff Lindsay for the gevent server implementation. https://github.com/progrium pywebsocket and Tornado for their implementations that were a fantastic starting point. Have fun, -- - Sylvain http://www.defuze.org http://twitter.com/lawouach

PySide project future
by matti.p.airas＠nokia.com 23 Aug '11

23 Aug '11

Hi all, The PySide: Python for Qt project was launched in public almost exactly two years ago. In the past two years, the project has matured, and we have a considerable user base for both the generator toolchain and the bindings, as well as a vivid community. Currently, the vast majority of the PySide core development is done by the OpenBossa INdT team in Brazil and funded by Nokia's MeeGo Computers team - the PySide project has internally been an enabler for the MeeGo 1.2 Harmattan Python project. Unfortunately, the Nokia N9 is the only MeeGo (Harmattan) phone to be published by Nokia, and Nokia's MeeGo team is being ramped down already in the near future. Because of this, the Nokia MeeGo funding for PySide is slated to end after this year, and I have also failed to find a new sponsor for the project within Nokia. I'm hopeful that the project is already sufficiently healthy to stay alive and grow without Nokia acting as a midwife. This would imply the community to take a leading role in both the project guidance and actual development. I've outlined my own ideas and concerns in a mail to the PySide mailing list: http://lists.pyside.org/pipermail/pyside/2011-August/002816.html If you are interested in voicing your opinion or participating in PySide's future development, please join the PySide mailing list and chime in! http://lists.pyside.org/listinfo/pyside Cheers, Matti Airas
