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!

***********************************************************
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.

A huge hit at PyCon-Au last year, Code War is back!
Eight teams, onstage knockout rounds of short programming bouts, loud
crowd...mildly impressive prizes. Any language allowed, no holds
bared. Think of it like cage fighting for coders.
Originally based on an idea from the book PeopleWare, CodeWar has been
run in conjunction with the Sydney WebDU conference since 2008 with
great success. To help share the mayhem we're proud to bring CodeWar
to PyCon-au 2011, with experienced CodeWar compare Robin Hilliard from
RocketBoots on the microphone to keep a wry eye on proceedings.
All comers welcome -- no conference ticket required. Come to compete
or just come to watch. RSVP now!
If you want to enter a team read on...
Tourney Rules
-------------
The competition will consist of three rounds:
* 8 teams of 3-5 people
* 1 laptop per team connected to projector on stage.
* Rounds are first-past-the-post simple programming challenges
* Any programming language you want.
We guarantee this won't be mind twisting problems for algorithm heads.
It will help to have a team with a mix of skills, a clever and/or
intimidating team name and vocal cheer squad.
For example: "Here is the complete text of pride and prejudice on this
usb key. Be the first to print out the 7th and 25th sentances that
contain both 'Elizabeth'and 'Darcy'". See a list of questions from
recent code war events.
If you're registering a team, the team leader should get 1 team leader
ticket and the team members a RSVP ticket. Don't forget to bring your
team and single laptop on the day.
If all the team slots are gone register your standby team in case of a
no-show.

Here an attempt of translated Python 3: replacing the english words
( operators, names and messages - if,else,for,..) with another language
- e.g. bulgarian (ако,иначе,за). For kids, and people who want to think
and write in their own language, instead of suffer with the
alternatives - near-"english", transliteration into latin, mixed
latin-cyrilic, whatever.
клас Филминфо( Инфо): #изцяло преведено / fully translated
@класметод
деф сглоби_име( кл, име ):
имена = [ име ]
ако име.завършва('.bg'): имена.допълни( име[:-3])
инако име.завършва('.ru'): имена.допълни( име[:-3])
иначе: имена.допълни( име)
върни Инфо.сглоби_име( *имена)
class Filminfo( Info): #изцяло на английски / fully in english
@classmethod
def make_name( kl, name):
names = [ name]
if name.endswith('.bg'): names.append( ime[:-3])
elif name.endswith('.ru'): names.append( име[:-3])
else: names.append( ime)
return Info.make_name( *names)
it's work in progress, so far in bulgarian only, but it's a couple of dictionaries.
Plenty of things to do like translating error messages, some builtins
and some types' methods... hands are always needed.

PyCon Australia 2011
I'd like to announce Pyrolite 1.1, a lightweight Pyro client library for Java and .NET
"what is a java/.net library doing in this Python newsgroup?"
If you've got a Python application and you find yourself wanting to access it from the
harsh world of java or .net, Pyrolite could be of help. This library is meant to connect
a java or .net program to Python in a very simple way, using the Pyro protocol. Pyro is
a remote object library that is written for Python. Pyro itself can also be used in
Jython or IronPython, so you can already call Python applications from java or .net
(using Pyro), but sometimes that is just too much weight if you only need to call a few
methods. So I decided to explore the possibilities of a thin client-only library for
java and .Net.
Download Pyrolite here: http://irmen.home.xs4all.nl/pyrolite/
(Readme.txt, java jar, .NET assembly DLL, source code archive, javadocs).
Readonly subversion access: svn://svn.razorvine.net/Various/Pyrolite/
More info on Pyro: http://irmen.home.xs4all.nl/pyro/
---DETAILS---
Pyrolite allows you to connect your Java or .NET program to Python in an extremely
straightforward way, using the Pyro protocol. Include this tiny library (~50kb), and off
you go. It contains:
- an almost fully functional pickle implementation (protocol 2)
- a fully functional unpickle implementation (protocols 0,1,2,3)
- fairly intelligent mapping of Python data types to Java/.NET data types and vice versa
- ofcourse, a subset of the client-side of the Pyro protocol and proxy logic.
Example program (java): http://paste.pocoo.org/show/438990/
The .NET version of this would be almost equivalent.
The Pyrolite source archive includes all source code, a couple of test programs, and a
large amount of unit tests (everything in java and C#). There is not much documentation
though - use the source, Luke... (or browse the javadocs).
Pyrolite only supports Pyro 4.x.
Pyrolite for java requires java 1.5. The project is done in Pycharm.
Pyrolite for .NET requires .NET 3.5 or Mono. The solution is done in
sharpdevelop/monodevelop (but probably works in visual studio too).
I've done quite some work to make this a stable and usable piece of software but
consider it an experiment, or a beta version. I am quite interested in your thoughts
about it. Let me know if you find it useful!

gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the
CPython interpreter within GCC, allowing you to write new compiler
warnings in Python, generate code visualizations, etc.
Tarball releases are available at:
https://fedorahosted.org/releases/g/c/gcc-python-plugin/
Prebuilt-documentation can be seen at:
http://readthedocs.org/docs/gcc-python-plugin/en/latest/index.html
Project homepage:
https://fedorahosted.org/gcc-python-plugin/
High level summary of the changes since the initial announcement:
- new contributors
- lots of bug fixes and compatibility fixes (e.g. for Python 3): the
selftest suite now works for me with all eight different
combinations of:
- optimized vs debug builds of Python
- Python 2.7 vs Python 3.2
- i686 and x86_64
building against gcc-4.6.1 (also tested with gcc-4.6.0)
- new example scripts; see:
http://readthedocs.org/docs/gcc-python-plugin/en/latest/examples.html
- if PLUGIN_PYTHONPATH is defined at build time, hardcode the value
into the plugin's sys.path, allowing multiple builds to be
independently packaged
- more documentation
- work-in-progress on detecting reference-count errors in C Python
extension code. Although this usage example can now detect errors,
it isn't yet ready for general use. It can generate HTML
visualizations of those errors; see
http://dmalcolm.livejournal.com/6560.html
for examples.
- numerous other improvements (see below)
- new dependency: the "six" module is required at both build time and
run-time, to smooth over Python 2 vs Python 3 differences:
http://pypi.python.org/pypi/six/
I've also packaged the plugin in RPM form for Fedora 16 onwards; see:
https://fedoraproject.org/wiki/Features/GccPythonPlugin
Enjoy!

Announcing
----------
Release files for *both* wxPython 2.8.12.1 *and* 2.9.1.1 are now
available for download at http://wxpython.org/download.php.
The 2.8.12.1 release is a minor update from 2.8.12.0 which relaxes an
assertion in the Bind method which prevented the use of None as the
handler, (which can be used to remove an event binding). Also
included are updates from contributed modules like AGW.
The 2.9.2.1 release adds some new features and lots of general
improvements and fixes for the development series of wxWidgets and
wxPython. There have been a number of improvements in the wxOSX-Cocoa
port, making it much more usable and stable. Please see the recent
changes document for more details. http://wxpython.org/recentchanges.php
Various binaries are available for 32-bit and 64-bit Windows, and also
for OSX using the Carbon and Cocoa APIs, for Python 2.6 and 2.7, and
source code is also available at http://wxpython.org/download.php of
course for building your own.
What is wxPython?
-----------------
wxPython is a GUI toolkit for the Python programming language. It
allows Python programmers to create programs with a robust, highly
functional graphical user interface, simply and easily. It is
implemented as a set of Python extension modules that wrap the GUI
components of the popular wxWidgets cross platform library, which is
written in C++.
wxPython is a cross-platform toolkit. This means that the same program
will usually run on multiple platforms without modifications.
Currently supported platforms are 32-bit and 64-bit Microsoft Windows,
most Linux or other Unix-like systems using GTK2, and Mac OS X 10.4+.
In most cases the native widgets are used on each platform to provide
a 100% native look and feel for the application.
