HTSQL 2.1-RC1 : A Query Language for the Accidental Programmer
by Clark C. Evans 15 Dec '11

15 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. 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.

29 Sep '11

The deadline for PyCon 2012 tutorial, talk, and poster proposals is under 15 days away, so be sure to get your submissions in by October 12, 2011. Whether you’re a first-timer or an experienced veteran, PyCon is depends on you, the community, coming together to build the best conference schedule possible. Our call for proposals (http://us.pycon.org/2012/cfp/) lays out the details it takes to be included in the lineup for the conference in Santa Clara, CA on March 7-15, 2012. If you’re unsure of what to write about, our recent survey yielded a large list of potential talk topics (http://pycon.blogspot.com/2011/09/need-talk-ideas.html), and plenty of ideas for tutorials (http://pycon.blogspot.com/2011/09/need-tutorial-ideas.html). We’ve also come up with general tips on proposal writing at http://pycon.blogspot.com/2011/08/writing-good-proposal.html to ensure everyone has the most complete proposal when it comes time for review. As always, the program committee wants to put together an incredible conference, so they’ll be working with submitters to fine tune proposal details and help you produce the best submissions. We’ve had plenty of great news to share since we first announced the call for proposals. Paul Graham of Y Combinator was recently announced as a keynote speaker (http://pycon.blogspot.com/2011/09/announcing-first-pycon-2012-keynote.html), making his return after a 2003 keynote. David Beazley, famous for his mind-blowing talks on CPython’s Global Interpreter Lock, was added to the plenary talk series (http://pycon.blogspot.com/2011/09/announcing-first-pycon-2012-plenary.html). Sponsors can now list their job openings on the “Job Fair” section of the PyCon site (http://pycon.blogspot.com/2011/09/announcing-pycon-2012-fair-page-sponsor.h…). We’re hard at work to bring you the best conference yet, so stay tuned to PyCon news at http://pycon.blogspot.com/ and on Twitter at https://twitter.com/#!/pycon.

** FINAL CALL ** http://sfbay.craigslist.org/sfc/cls/2495963854.html ---------- Forwarded message ---------- From: wesley chun <wescpy(a)gmail.com> Date: Mon, Jul 25, 2011 at 12:32 PM Subject: ANN: Intro+Intermediate Python course, SF, Oct 18-20 Need to get up-to-speed with Python as quickly and as in-depth as possible? Already coding Python but still have areas of uncertainty you need to fill? Then come join me, Wesley Chun, author of Prentice-Hall's bestseller "Core Python" for a comprehensive intro/intermediate course coming up this May in Northern California, then enjoy a beautiful Fall weekend afterwards in San Francisco, the beautiful city by the bay. Please pass on this note to whomever you think may be interested. I look forward to meeting you and your colleagues! Feel free to pass around the PDF flyer linked down below. Write if you have questions. Since I hate spam, I'll only send out one reminder as the date gets closer. (Comprehensive) Intro+Intermediate Python Tue-Thu, 2011 Oct 18-20, 9am-5pm Hope to meet you soon! -Wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (COMPREHENSIVE) INTRO+INTERMEDIATE PYTHON Although this course may appear to those new to Python, it is also perfect for those who have tinkered with it and want to "fill in the gaps" and/or want to get more in-depth formal training. It combines the best of both an introduction to the language as well as a "Python Internals" training course. We will immerse you in the world of Python in only a few days, showing you more than just its syntax (which you don't really need a book to learn, right?). Knowing more about how Python works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer coming out of the gate. 3 hands-on labs each day will help hammer the concepts home. Come find out why Google, Yahoo!, Disney, ILM/LucasFilm, VMware, NASA, Ubuntu, YouTube, and Red Hat all use Python. Users supporting or jumping to Plone, Zope, TurboGears, Pylons, Django, Google App Engine, Jython, IronPython, and Mailman will also benefit! PREVIEW 1: you will find (and can download) a video clip of a class session recorded live to get an idea of my lecture style and the interactive classroom environment (as well as sign-up) at: http://cyberwebconsulting.com PREVIEW 2: Partnering with O'Reilly and Pearson, Safari Books Online has asked me to deliver a 1-hour webcast a couple of years ago called "What is Python?". This was an online seminar based on a session that I've delivered at numerous conferences in the past.

ANN: PyTables 2.3 released
by Antonio Valentino 24 Sep '11

24 Sep '11

=========================== Announcing PyTables 2.3 =========================== We are happy to announce PyTables 2.3. This release comes after about 10 months of development and after that Francesc Altet, the creator of PyTables, ceased activities with the project. Thank you Francesc. Also the project has been moved to GitHub: http://github.com/PyTables/PyTables. What's new ========== The main new features in 2.3 series are: * PyTables now includes the codebase of PyTables Pro (now release under open source license) gaining a lot of performance improvements and some new features like: - the new and powerful indexing engine: OPSI - a fine-tuned LRU cache for both metadata (nodes) and regular data * The entire documentation set has been converted to ReStructuredTest and Sphinx As always, a large amount of bugs have been addressed and squashed too. In case you want to know more in detail what has changed in this version, have a look at: http://pytables.github.com/release_notes.html You can download a source package with generated PDF and HTML docs, as well as binaries for Windows, from: http://sourceforge.net/projects/pytables/files/pytables/2.3 For an on-line version of the manual, visit: http://pytables.github.com/usersguide/index.html What it is? =========== PyTables is a library for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data with support for full 64-bit file addressing. PyTables runs on top of the HDF5 library and NumPy package for achieving maximum throughput and convenient use. PyTables includes OPSI, a new indexing technology, allowing to perform data lookups in tables exceeding 10 gigarows (10**10 rows) in less than 1 tenth of a second. Resources ========= About PyTables: http://www.pytables.org About the HDF5 library: http://hdfgroup.org/HDF5/ About NumPy: http://numpy.scipy.org/ Acknowledgments =============== Thanks to many users who provided feature improvements, patches, bug reports, support and suggestions. See the ``THANKS`` file in the distribution package for a (incomplete) list of contributors. Most specially, a lot of kudos go to the HDF5 and NumPy (and numarray!) makers. Without them, PyTables simply would not exist. Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. ---- **Enjoy data!** -- The PyTables Team

pytest-2.1.2: bug fixes and fixes for jython
by holger krekel 24 Sep '11

24 Sep '11

pytest-2.1.2 is a minor backward compatible maintenance release of the popular py.test testing tool. pytest is commonly used for unit, functional- and integration testing. See extensive docs with examples here: http://pytest.org/ Most bug fixes address remaining issues with the perfected assertions introduced in the 2.1 series - many thanks to the bug reporters and to Benjamin Peterson for helping to fix them. pytest should also work better with Jython-2.5.1 (and Jython trunk, but not Jython-2.5.2). If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest best, holger krekel / http://merlinux.eu Changes between 2.1.1 and 2.1.2 ---------------------------------------- - fix assertion rewriting on files with windows newlines on some Python versions - refine test discovery by package/module name (--pyargs), thanks Florian Mayer - fix issue69 / assertion rewriting fixed on some boolean operations - fix issue68 / packages now work with assertion rewriting - fix issue66: use different assertion rewriting caches when the -O option is passed - don't try assertion rewriting on Jython, use reinterp

MailingLogger 3.5.0 Released!
by Chris Withers 24 Sep '11

24 Sep '11

I'm pleased to announce a new release of Mailinglogger. Mailinglogger provides two handlers for the standard python logging framework that enable log entries to be emailed either as the entries are logged or as a summary at the end of the running process. The handlers have the following features: - customisable and dynamic subject lines for emails sent - emails sent with a configurable headers for easy filtering - flood protection to ensure the number of emails sent is not excessive - support for SMTP servers that require authentication - fully documented and tested The only change for this release was to add an X-Log-Level header to emails sent. For MailingLogger, this is the level of the log message being emailed. For SummarisingLogger this is the highest level of any of the messages handled. Full docs can be found here: http://packages.python.org/mailinglogger/ For more information, please see: http://www.simplistix.co.uk/software/python/mailinglogger or http://pypi.python.org/pypi/mailinglogger cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
