We are pleased to announce the keynote speakers for this year's
Vancouver Python Workshop: Guido van Rossum and Jim Hugunin.
Guido van Rossum (Google) is the inventor of Python and has managed its
growth and development for more than a decade. Guido was awarded the
Free Software Foundation Award in 2002 and Dr.Dobb's 1999 Excellence in
Programming Award. Today Guido works at Google, spending half of his
time on Python.
Jim Hugunin (Microsoft) is the creator of IronPython, Jython and Numeric
Python. IronPython is Python for the .NET platform and integrates Python
into Microsoft's .NET strategy. Jython is Python for the Java platform
and was the second production quality implementation of Python. Numeric
Python adapts Python to the needs of number crunching applications.
Today, Jim works at Microsoft where he helps them adapt the .NET runtime
to meet the needs of dynamic languages like Python.

* buildpackage: fixed missing DEBUILDER environment variable bug
* dos2unix: removal (unused, buggy, conflicts with debian package tofrodos)
* debianize: fix the way to handle subpackage's __init__.py file (there
is now a subpackage_master boolean property in the __pkginfo__.py which
tells if a package is handling the __init__.py file, so now only one
subpackage should set this to True and the others should depends on
* debianize: fix Uploader to Uploaders in control
* pkginfo: fix debian handler detection
* makedistrib: don't ask to tag package if an error occurs
* vcslib: added mercurial support

The Open Source Developers' Conference is an Australian conference
designed for developers, by developers. It covers numerous programming
languages across a range of operating systems. We're seeking papers on
Open Source languages, technologies, projects and tools as well as topics
of interest to Open Source developers.
The conference will be held in Melbourne, Victoria (Monash University's
Caulfield Campus) from the 6th to the 8th of December, 2006.
Last year's conference had about 160 people and around 60 presentations on
a range of topics - see http://osdc2005.cgpublisher.com/proposals/ for a
list. This list might also be useful if you're looking for ideas on what
sort of thing would be appropriate.
If you have any questions, or have never submitted a paper proposal
before, please read our FAQ page at http://www.osdc.com.au/faq/index.html
If you don't find an answer there, please contact richard(a)osdc.com.au
To submit a proposal, follow the instructions at
This year we're also going to run a day of tutorials. See the CFP
for more information.
The deadline for proposals is 12th July 2006.
Hope to see you there!

The Python Quick Reference Card (PQRC) aims to provide a printable quick
reference documentation for the Python language and some of its main
standard libraries (currently for Python 2.4).
PQRC tries to group informations about same/similar subject to avoid
searching in multiple places.

The deadline for abstract submission for EuroPython 2006 is just
two days away.
If you've been planning to submit a talk but haven't gotten
around to it yet, now's the time to do it. On the other hand, if
you haven't considered speaking yet, maybe you should think about
it. The audience at EuroPython is well-informed, interested and
friendly -- there's no finer place to talk about your research,
experience or project.
In either case, get yourself to:
before midnight (CEST) on the 31st of May.

Pycairo is a set of Python bindings for the multi-platform 2D graphics
A new pycairo snapshot release 1.1.6 is now available from:
Overview of changes from pycairo 1.0.2 to pycairo 1.1.6
Pycairo has been updated to work with cairo 1.1.6.
Note that cairo 1.1.6 is a development version and not a fully stable
release, the stable release 1.2.0 is due soon.
PDFSurface()/PSSurface() - can now write to file-like objects (like
surface.write_to_png() and ImageSurface.create_from_png() can now
write to file-like objects (like StringIO).
select_font_face, show_text, text_extents and text_path now accept
misc bug fixes.

buzhug is a new, fast, pure-Python database engine, using a pythonic
syntax (no SQL). It is published at http://buzhug.sourceforge.net under
the BSD licence
Here is an overview of the interface :
from buzhug import Base
my_cds = Base('my_cds')
my_cds.insert(artist='Rialto',title='Night On Earth',issued=2002)
cd = my_cds.select(artist="Oasis")
> "Definitely Maybe"
new_cds = [ cd for cd in my_cds if cd.issued > 2000 ]
Pretty straightforward, isn't it ? As you can see on the last line, the
database is an iterator, yielding objects which have attributes of the
same name as the fields in the base
songs = Base('songs')
cd = my_cds.select(title="Definitely Maybe")
song_id = songs.insert('Supersonic',cd)
song = songs[song_id] # lookup by record id
A field can be a reference to another database. When you have finished
entering all the songs you can get the track listing by
[ song.title for song in songs if song.cd.title == "Definitely
A complete documentation, with a tutorial, is available on the web site
The implementation has been designed to make all operations, especially
selection, as fast as possible, while processing the data on disk (it
is not an in-memory database). On a limited set of tests I found that
it is much faster than gadfly and KirbyBase, and only less than 3 times
slower than SQLite
This is still a beta version, so I need feedback on the syntax,
performance, bug reports etc. Please send any comment or question to
the Google group : http://groups.google.com/group/buzhug?lnk=li
