Subject: Python Wins "Favorite Scripting Language" Award
Message-ID: <481A1CF9.1010106@holdenweb.com>

The Linux Journal readers apparently suffer the same ambiguity as the 
rest of us when it comes to defining what the difference between a 
scripting language and a programming language.

They do, however, clearly like Python, which they voted their scripting 
language of 2008. PHP, Bash and Perl came in reasonably close on 
Python's heels, but 28.9% of those voting voted for Python.

Subject: Bazaar 1.4 released
Message-ID: <20080502050440.GI13540@sourcefrog.net>

On behalf of the developers of the Bazaar version control system I'd
like to announce our 1.4 release, available now from
<http://bazaar-vcs.org/Download/>

Thanks very much to all the people who contributed patches, bug reports,
suggestions and feedback for this release.

Martin



bzr 1.4 2008-04-28
------------------

This release of Bazaar includes handy improvements to the speed of log and
status, new options for several commands, improved documentation, and better
hooks, including initial code for server-side hooks.  A number of bugs have
been fixed, particularly in interoperability between different formats or
different releases of Bazaar over there network.  There's been substantial
internal work in both the repository and network code to enable new features
and faster performance.

  BUG FIXES:

    * Pushing a branch in "dirstate" format (Branch5) over bzr+ssh would break
      if the remote server was < version 1.2.  This was due to a bug in the
      RemoteRepository.get_parent_map() fallback code.
      (John Arbash Meinel, Andrew Bennetts, #214894)


bzr 1.4rc2 2008-04-21
---------------------

  BUG FIXES:

    * ``bzr log -r ..X bzr://`` was failing, because it was getting a request
      for ``revision_id=None`` which was not a string.
      (John Arbash Meinel, #211661)

    * Fixed a bug in handling ghost revisions when logging changes in a 
      particular file.  (John Arbash Meinel, #209948)

    * Fix error about "attempt to add line-delta in non-delta knit".
      (Andrew Bennetts, #205156)

    * Fixed performance degradation in fetching from knit repositories to
      knits and packs due to parsing the entire revisions.kndx on every graph
      walk iteration fixed by using the Repository.get_graph API.  There was
      another regression in knit => knit fetching which re-read the index for
      every revision each side had in common.
      (Robert Collins, John Arbash Meinel)


bzr 1.4rc1 2008-04-11
---------------------

  NOTES WHEN UPGRADING:

  CHANGES:

   * bzr main script cannot be imported (Benjamin Peterson)

   * On Linux bzr additionally looks for plugins in arch-independent site
     directory. (Toshio Kuratomi)

   * The ``set_rh`` branch hook is now deprecated. Please migrate
     any plugins using this hook to use an alternative, e.g.
     ``post_change_branch_tip``. (Ian Clatworthy)

   * When a plugin cannot be loaded as the file path is not a valid
     python module name bzr will now strip a ``bzr_`` prefix from the
     front of the suggested name, as many plugins (e.g. bzr-svn)
     want to be installed without this prefix. It is a common mistake
     to have a folder named "bzr-svn" for that plugin, especially
     as this is what bzr branch lp:bzr-svn will give you. (James Westby,
     Andrew Cowie)

   * UniqueIntegerBugTracker now appends bug-ids instead of joining
     them to the base URL. Plugins that register bug trackers may
     need a trailing / added to the base URL if one is not already there.
     (James Wesby, Andrew Cowie)

  FEATURES:

    * Added mail-mode GNU Emacs mail package as a mail_client.
      (Xavier Maillard, Bojan Nikolic)

    * Added start_commit hook for mutable trees. (Jelmer Vernooij, #186422)

    * ``status`` now accepts ``--no-pending`` to show the status without
      listing pending merges, which speeds up the command a lot on large
      histories.  (James Westby, #202830)

    * New ``post_change_branch_tip`` hook that is called after the
      branch tip is moved but while the branch is still write-locked.
      See the User Reference for signature details.
      (Ian Clatworthy, James Henstridge)

  IMPROVEMENTS:

    * The smart protocol now has support for setting branches' revision info
      directly.  This should make operations like push slightly faster, and is a
      step towards server-side hooks.  The new request method name is
      ``Branch.set_last_revision_info``.  (Andrew Bennetts)

    * ``bzr commit --fixes`` now recognises "gnome" as a tag by default.
      (James Westby, Andrew Cowie)

    * ``bzr switch`` will attempt to find branches to switch to relative to the
      current branch. E.g. ``bzr switch branchname`` will look for
      ``current_branch/../branchname``. (Robert Collins, Jelmer Vernooij,
      Wouter van Heyst)

    * Diff is now more specific about execute-bit changes it describes
      (Chad Miller)

    * Fetching data over HTTP is a bit faster when urllib is used.  This is done
      by forcing it to recv 64k at a time when reading lines in HTTP headers,
      rather than just 1 byte at a time.  (Andrew Bennetts)

    * Log --short and --line are much faster when -r is not specified.
      (Aaron Bentley)

    * Merge is faster.  We no longer check a file's existence unnecessarily
      when merging the execute bit.  (Aaron Bentley)

    * ``bzr status`` on an explicit list of files no longer shows pending
      merges, making it much faster on large trees. (John Arbash Meinel)

    * The launchpad directory service now warns the user if they have not set
      their launchpad login and are trying to resolve a URL using it, just
      in case they want to do a write operation with it.  (James Westby)

    * The smart protocol client is slightly faster, because it now only queries
      the server for the protocol version once per connection.  Also, the HTTP
      transport will now automatically probe for and use a smart server if
      one is present.  You can use the new ``nosmart+`` transport decorator
      to get the old behaviour.  (Andrew Bennetts)

    * The ``version`` command takes a ``--short`` option to print just the
      version number, for easier use in scripts.  (Martin Pool)

    * Various operations with revision specs and commands that calculate
      revnos and revision ids are faster.  (John A. Meinel, Aaron Bentley)

  BUGFIXES:

    * Add ``root_client_path`` parameter to SmartWSGIApp and
      SmartServerRequest.  This makes it possible to publish filesystem
      locations that don't exactly match URL paths. SmartServerRequest
      subclasses should use the new ``translate_client_path`` and
      ``transport_from_client_path`` methods when dealing with paths received
      from a client to take this into account.  (Andrew Bennetts, #124089)

    * ``bzr mv a b`` can be now used also to rename previously renamed
      directories, not only files. (Luk?? Lalinsk?, #107967)

    * ``bzr uncommit --local`` can now remove revisions from the local
      branch to be symmetric with ``bzr commit --local``.
      (John Arbash Meinel, #93412)

    * Don't ask for a password if there is no real terminal.
      (Alexander Belchenko, #69851)

    * Fix a bug causing a ValueError crash in ``parse_line_delta_iter`` when
      fetching revisions from a knit to pack repository or vice versa using
      bzr:// (including over http or ssh).
      (#208418, Andrew Bennetts, Martin Pool, Robert Collins)

    * Fixed ``_get_line`` in ``bzrlib.smart.medium``, which was buggy.  Also
      fixed ``_get_bytes`` in the same module to use the push back buffer.
      These bugs had no known impact in normal use, but were problematic for
      developers working on the code, and were likely to cause real bugs sooner
      or later.  (Andrew Bennetts)

    * Implement handling of basename parameter for DefaultMail.  (James Westby)

    * Incompatibility with Paramiko versions newer than 1.7.2 was fixed.
      (Andrew Bennetts, #213425)

    * Launchpad locations (lp: URLs) can be pulled.  (Aaron Bentley, #181945)

    * Merges that add files to deleted root directories complete.  They
      do create conflicts.  (Aaron Bentley, #210092)

    * vsftp's return ``550 RNFR command failed.`` supported.
      (Marcus Trautwig, #129786)

  DOCUMENTATION:

    * Improved documentation on send/merge relationship. (Peter Schuller)

    * Minor fixes to the User Guide. (Matthew Fuller)

    * Reduced the evangelism in the User Guide. (Ian Clatworthy)

    * Added Integrating with Bazaar document for developers (Martin Albisetti)

  API BREAKS:

    * Attempting to pull data from a ghost aware repository (e.g. knits) into a
      non-ghost aware repository such as weaves will now fail if there are
      ghosts.  (Robert Collins)

    * ``KnitVersionedFile`` no longer accepts an ``access_mode`` parameter, and
      now requires the ``index`` and ``access_method`` parameters to be
      supplied. A compatible shim has been kept in the new function
      ``knit.make_file_knit``. (Robert Collins)

    * Log formatters must now provide log_revision instead of show and
      show_merge_revno methods. The latter had been deprecated since the 0.17
      release. (James Westby)

    * ``LoopbackSFTP`` is now called ``SocketAsChannelAdapter``.
      (Andrew Bennetts)

    * ``osutils.backup_file`` is removed. (Alexander Belchenko)

    * ``Repository.get_revision_graph`` is deprecated, with no replacement
      method. The method was size(history) and not desirable. (Robert Collins)

    * ``revision.revision_graph`` is deprecated, with no replacement function.
      The function was size(history) and not desirable. (Robert Collins)

    * ``Transport.get_shared_medium`` is deprecated.  Use
      ``Transport.get_smart_medium`` instead.  (Andrew Bennetts)

    * ``VersionedFile`` factories now accept a get_scope parameter rather
      than using a call to ``transaction_finished``, allowing the removal of
      the fixed list of versioned files per repository. (Robert Collins)

    * ``VersionedFile.annotate_iter`` is deprecated. While in principle this
      allowed lower memory use, all users of annotations wanted full file 
      annotations, and there is no storage format suitable for incremental
      line-by-line annotation. (Robert Collins)

    * ``VersionedFile.clone_text`` is deprecated. This performance optimisation
      is no longer used - reading the content of a file that is undergoing a
      file level merge to identical state on two branches is rare enough, and
      not expensive enough to special case. (Robert Collins)

    * ``VersionedFile.clear_cache`` and ``enable_cache`` are deprecated.
      These methods added significant complexity to the ``VersionedFile``
      implementation, but were only used for optimising fetches from knits - 
      which can be done from outside the knit layer, or via a caching
      decorator. As knits are not the default format, the complexity is no
      longer worth paying. (Robert Collins)

    * ``VersionedFile.create_empty`` is removed. This method presupposed a
      sensible mapping to a transport for individual files, but pack backed
      versioned files have no such mapping. (Robert Collins)

    * ``VersionedFile.get_graph`` is deprecated, with no replacement method.
      The method was size(history) and not desirable. (Robert Collins)

    * ``VersionedFile.get_graph_with_ghosts`` is deprecated, with no
      replacement method.  The method was size(history) and not desirable.
      (Robert Collins)

    * ``VersionedFile.get_parents`` is deprecated, please use
      ``VersionedFile.get_parent_map``. (Robert Collins)

    * ``VersionedFile.get_sha1`` is deprecated, please use
      ``VersionedFile.get_sha1s``. (Robert Collins)

    * ``VersionedFile.has_ghost`` is now deprecated, as it is both expensive
      and unused outside of a single test. (Robert Collins)

    * ``VersionedFile.iter_parents`` is now deprecated in favour of
      ``get_parent_map`` which can be used to instantiate a Graph on a
      VersionedFile. (Robert Collins)

  TESTING:

    * New -Dselftest_debug flag disables clearing of the debug flags during
      tests.  This is useful if you want to use e.g. -Dhpss to help debug a
      failing test.  Be aware that using this feature is likely to cause
      spurious test failures if used with the full suite. (Andrew Bennetts)

    * selftest --load-list now uses a new more agressive test loader that will
      avoid loading unneeded modules and building their tests. Plugins can use
      this new loader by defining a load_tests function instead of a test_suite
      function. (a forthcoming patch will provide many examples on how to
      implement this).
      (Vincent Ladeuil)

    * selftest --load-list now does some sanity checks regarding duplicate test
      IDs and tests present in the list but not found in the actual test suite.
      (Vincent Ladeuil)

    * Slightly more concise format for the selftest progress bar, so there's
      more space to show the test name.  (Martin Pool) ::

        [2500/10884, 1fail, 3miss in 1m29s] test_revisionnamespaces.TestRev

    * The test suite takes much less memory to run, and is a bit faster.  This
      is done by clearing most attributes of TestCases after running them, if
      they succeeded.  (Andrew Bennetts)

  INTERNALS:

    * Added ``_build_client_protocol`` to ``_SmartClient``.  (Andrew Bennetts)

    * Added basic infrastructure for automatic plugin suggestion.
      (Martin Albisetti)

    * If a ``LockableFiles`` object is not explicitly unlocked (for example
      because of a missing ``try/finally`` block, it will give a warning but
      not automatically unlock itself.  (Previously they did.)  This
      sometimes caused knock-on errors if for example the network connection
      had already failed, and should not be relied upon by code. 
      (Martin Pool, #109520)

    * ``make dist`` target to build a release tarball, and also 
      ``check-dist-tarball`` and ``dist-upload-escudero``.  (Martin Pool)

    * The ``read_response_tuple`` method of ``SmartClientRequestProtocol*``
      classes will now raise ``UnknownSmartMethod`` when appropriate, so that
      callers don't need to try distinguish unknown request errors from other
      errors.  (Andrew Bennetts)

    * ``set_make_working_trees`` is now implemented provided on all repository
      implementations (Aaron Bentley)

    * ``VersionedFile`` now has a new method ``get_parent_map`` which, like
      ``Graph.get_parent_map`` returns a dict of key:parents. (Robert Collins)

Message-ID: <b18aee17-fc11-474a-82d6-0e09504ace39@k13g2000hse.googlegroups.com>

Hi,

My forthcoming book:

"Programming in Python 3: A Complete Introduction to the Python
Language"

is now available from Safari Books Online. The online version contains
about half the book so far and is about six weeks behind my working
copy. It is accurate for Python 3.0 alpha 4. More text will be added
and updates made as the book and Python progress.

The book began life last year once it was clear that Python 3 was
going to come out this year. The printed version should be available
in October in the U.S.---but it will only go to press once all the
examples and snippets have been tested against Python 3.0 final, so
the date will slip if Python's release date slips.

The book is aimed at a wide audience, but assumes some programming
experience (not necessarily Python, not necessarily object-oriented).
It teaches solid procedural style programming, then builds on that to
teach solid object-oriented programming, and then goes on to more
advanced topics. But even newcomers to Python 3 should be able to
write useful (although small and basic) programs after reading chapter
1.

There is no Python 2 coverage (except for an appendix on migration),
so as to avoid confusion and to allow the book to use Python 3 to its
best advantage.

Clearly Python 3 is going to change between now and September, but the
book is up to date now, and will continue to be kept up to date as
every alpha, beta, and release candidate is made available.

The table of contents, a brief overview, and some very short extracts
are available from the Safari site:

http://safari.informit.com/9780137155149

The book is being greatly benefited by feedback from several technical
reviewers, including Jasmin Blanchette, David Boddie, Georg Brandl,
Trenton Schulz, and Phil Thompson.

We're pleased to announce the release of IronPython 2.0 Beta 2.  In addition to the usual bug fixes (~25 reported on CodePlex and ~50 reported internally), this release has been partially focused on improving the performance of IronPython, in particular startup perf.  Another focus of this release was improving upon our traceback support which had regressed quite a bit in 2.0B1 and had largely been broken in the 2.0 Alphas.  Our traceback support should now be superior to that of IronPython 1.1!

We've also made a minor change to our packaging by adding a Microsoft.Scripting.Core.dll in addition to the Microsoft.Scripting.dll that's been around since the start of 2.0.  We are doing this purely as an architectural layering cleanup.  Microsoft.Scripting.Core contains DLR features that are essential to building dynamic languages.  Microsoft.Scripting will contain language implementation helpers that can either be re-used (e.g., BigInts) or copied (possibly e.g., the default binder).  This process is all about our work to get the DLR architecture right and shouldn't have any noticeable IronPython impact except that there's now one more DLL to include in any package.

As a consequence of the new DLL, the deprecated file IronPython2005.sln is broken.  This is the last release that will include this .sln file in the source zip file.  Of course the Visual Studio 2008 version of this file, IronPython.sln, still builds.

We'd like to thank everyone in the community who reported bugs on CodePlex that were fixed in this release: kevgu, oldman, christmas, brucec, scottw, fuzzyman, haibo, Seo Sanghyeon, grizlupo, J. Merrill, perhaps, antont, 05031972, Jason Ferrara, Matt Beckius, and Davy Mitchell.

Subject: ANN: Porcupine 0.5 is released. More Pythonic, more productive.
Message-ID: <b14d3167-f53a-4655-9c1e-08e4ef2e79cc@m45g2000hsb.googlegroups.com>

Porcupine Web Application Server is a Python based framework that
provides front-to-back revolutionary technologies for building modern
Web2.0 applications.

This release is a major breakthrough for Porcupine. The two main new
concepts introduced on the server side are the services and the web
methods. Porcupine's architecture is now based on configurable
services running over a common object database. Currently, the
supported service types include an asynchronous network server and a
scheduler used for executing Python code at predefined fixed
intervals. In the upcoming releases there are plans for new service
types to be added including persistent queues, loggers etc.

Web methods have replaced servlets completely and they are actually
smart Python decorators which allow you to add methods to content
classes dynamically (a technique also known as 'monkey-patching').
These methods become directly accessible over HTTP and they are mainly
used for serving all kinds of UIs and RPC requests.
Another major productivity enhancement is that this release no longer
requires heavy XML file editing. Thanks to web methods, the
"store.xml" is no longer used and the "config.xml" files for each
published directory can now contain smart registrations with regular
expressions matching becoming a powerful rewriting engine.

Other improvements include support for pre-processing filters, more
memory efficient object sets and type safe data types.

On the browser side QuiX has become less resource intensive by using a
pooled set of XMLHTTP objects and improved garbage collection. Last
but not least, the scroll bars bleed through issue on MacOS Firefox
browsers is now resolved.

Hello!

I'm pleased to announce version 0.9.6, a minor bug fix release of SQLObject.


What is SQLObject
=================

SQLObject is an object-relational mapper.  Your database tables are described
as classes, and rows are instances of those classes.  SQLObject is meant to be
easy to use and quick to get started with.

SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite,
Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB).

Message-ID: <20080504154057.GA24510@code0.codespeak.net>

=====================================================================
         PyPy Berlin Sprint (17-22nd May 2008)
=====================================================================

The next PyPy sprint will be in the crashed `c-base space station`_,
Berlin, Germany, Earth, Solar System.  This is a fully public sprint:
newcomers (from all planets) and topics other than those proposed below
are welcome.

.. _`c-base space station`: http://www.c-base.org/


------------------------------
Goals and topics of the sprint
------------------------------

  - work on PyPy's JIT generator: we are refactoring parts of the
    compiling logic, in ways that may also allow generating better
    machine code for loops (people or aliens with knowledge on
    compilers and SSA, welcome)

  - work on the SPy VM, PyPy's Squeak implementation, particularly the
    graphics capabilities

  - work on PyPy's GameBoy emulator, which also needs graphics support

  - trying some large pure-Python applications or libraries on PyPy and
    fixing the resulting bugs. Possibilities are Zope 3, Django and
    others.

* We are open to all sorts of other tasks during the sprint, just
  propose something.

-----------------------
Location & Accomodation
-----------------------

The sprint will take place in the c-base in Berlin. The address is::

    c-base e.V.
    Rungestrasse 20
    10179 Berlin

To get there, take the U-Bahn or S-Bahn to the station
"Jannowitzbruecke". See here_ for a map to get to c-base from there.

.. _here: http://maps.google.com/maps?f=q&hl=en&geocode=&q=c-base+berlin&ie=UTF8&ll=52.515464,13.408985&spn=0.020449,0.057335&z=15&iwloc=A

If you want to come, please register via by svn:

  http://codespeak.net/svn/pypy/extradoc/sprintinfo/berlin-2008/people.txt

or write a mail to the pypy-sprint mailing list if you do not yet have
check-in rights:

  http://codespeak.net/mailman/listinfo/pypy-sprint

Of course, especially given the location, it's ok to show up even if you
didn't register.  (The c-base has probably got the plans of Guido's
famous time machine anyway, so you can register last week.)


-----------
Exact times
-----------

The sprint will be from 17th to 22nd of May 2008. We will start
sprinting every day at 10. An introduction will be given on the first
day, if there is interest.

Subject: Sphinx 0.3 released
Message-ID: <48207225.9020709@python.org>

I'm pleased to announce the next minor version of Sphinx, the Python
documentation generation tool.

What is it?
===========

Sphinx is a tool that makes it easy to create intelligent and beautiful
documentation for Python projects (or other documents consisting of
multiple reStructuredText source files).

Its website is at <http://sphinx.pocoo.org/>.


Partial list of changes
=======================
(full list at http://sphinx.pocoo.org/changes.html)

* The ``toctree`` directive now supports a ``glob`` option that allows
   glob-style entries in the content.

* A new config value, `exclude_dirs`, can be used to exclude whole
   directories from the search for source files.

* The configuration directory (containing ``conf.py``) can now be set
   independently from the source directory.  For that, a new command-line
   option ``-c`` has been added.

* A new directive ``tabularcolumns`` can be used to give a tabular column
   specification for LaTeX output.  Tables now use the ``tabulary`` package.
   Table output is now much better, even with default settings.
   Literal blocks can now be placed in tables, with several caveats.

* A new config value, `latex_use_parts`, can be used to enable parts in LaTeX
   documents.

* Autodoc now skips inherited members for classes, unless you give the
   new ``inherited-members`` option.

* A new config value, `autoclass_content`, selects if the docstring of the
   class' ``__init__`` method is added to the directive's body.

* sphinx.ext.autodoc: descriptors are detected properly now.

* sphinx.latexwriter: implement all reST admonitions, not just ``note``
   and ``warning``.

* Lots of little fixes to the LaTeX output and style.


Enjoy!
Georg

demonstration at <http://pygments.org/demo>.

Highlights in this release are:

- Lexers added:

   * Io
   * Smalltalk
   * Darcs patches
   * Tcl
   * Matlab
   * Matlab sessions
   * FORTRAN
   * XSLT
   * tcsh
   * NumPy
   * Python 3
   * S, S-plus, R statistics languages
   * Logtalk

- Makefile lexer is now capable of handling BSD and GNU make syntax.

- In the LatexFormatter, the *commandprefix* option is now by default
   'PY' instead of 'C', since the latter resulted in several collisions
   with other packages.  Also, the special meaning of the *arg* argument
   to ``get_style_defs()`` was removed.

- Added ImageFormatter, to format code as PNG, JPG, GIF or BMP.
   (Needs the Python Imaging Library.)

- Support doc comments in the PHP lexer.

- Handle format specifications in the Perl lexer.

- Fix function and interface name highlighting in the Java lexer.

- Fix at-rule handling in the CSS lexer.

- Handle KeyboardInterrupts gracefully in pygmentize.

- Added BlackWhiteStyle.


I want to express my gratitude to all contributors who helped to build this
impressive feature list for 0.10. Thanks!

Cheers,
Georg

Subject: Pydev 1.3.16 Released
Message-ID: <cfb578b20805070716v5f0af286oe7289f53e9ec3907@mail.gmail.com>

Hi All,

Pydev and Pydev Extensions 1.3.16 have been released

Details on Pydev Extensions: http://www.fabioz.com/pydev
Details on Pydev: http://pydev.sf.net
Details on its development: http://pydev.blogspot.com

Release Highlights in Pydev Extensions:
-----------------------------------------------------------------

* Code Analysis: __path__ Not correctly found on some situations.
* Local rename (ctrl+2+r): Positions correctly ordered for tabbing.


Release Highlights in Pydev:
----------------------------------------------

* Interactive console: help() works
* Interactive console: context information showing in completions
* Interactive console: backspace will also delete the selected text
* Interactive console: ESC does not close the console when in floating
mode anymore
* Code completion: calltips context info correctly made 'bold'
* Code completion: variables starting with '_' do not come in import *
* Code completion: can be requested for external files (containing system info)
* Code completion: fixed recursion condition
* Code completion: egg file distributed with dll that has a source
module with the same name only with a __bootstrap__ method now loads
the dll instead of the source module (e.g.: numpy egg)
* Debugger: Step over/Step return can now execute with untraced frames
(much faster)
* Debugger: Problem when handling thread that had no context traced
and was directly removed.
* Launching: F9 will reuse an existing launch instead of creating a
new one every time
* Launching: The default launch with Ctrl+F11 will not ask again for
the launch associated with a file (for new launches -- old launches
should be deleted)
* Project Explorer: fixed integration problems with CDT (and others)
* Launch: console encoding passed as environment variable (no longer
written to the install location)
* More templates for "surround with" (Ctrl+1)
* Previous/next method could match 'class' and 'def' on invalid location
* Outline: Assign with multiple targets is recognized
* Bug fix for pydev package explorer when refreshed element parent was null



What is PyDev?
---------------------------

PyDev is a plugin that enables users to use Eclipse for Python and
Jython development -- making Eclipse a first class Python IDE -- It
comes with many goodies such as code completion, syntax highlighting,
syntax analysis, refactor, debug and many others.


Cheers,

Subject: ANN: Assembly Line 0.5
Message-ID: <68f4bmF2r1g5rU1@mid.individual.net>

I've uploaded a new version of my PyWeek 6 game, Assembly Line.

   http://media.pyweek.org/dl/6/gregpw6/AssemblyLine-0.5.zip

As a potential Pyggy entry, I'm keen to get some testing and feedback on it.

This version is greatly expanded. Some of the new features include:

     * More machine types and enhanced machine functionality
     * Simulation of a market that's buying your products
     * Multiple factories
     * Extensive reports showing what's going on with sales and finances
     * Sales and profit targets to aim for, and salary raises to seek after

Note that not all the products and machines are available at once now. The new 
machines will become available as the game progresses (about one every two 
months of game time) and you need to spend money to research new products.

I still haven't done much playtesting or balancing -- I've verified that the 
Phunky Phrisbee, Mojo Mallet and Supa Slice can be manufactured and sold at a 
profit, but I don't know about the others yet.

Subject: Plotdb fiction writer's database.
Message-ID: <Pine.LNX.4.64.0805080810300.11515@l748344.admin.ad.cnm.edu>

I am pleased to announce the availability of an application developed to 
aid fiction writers on Linux.  It is called plotdb, the plot database.  It 
is designed to help track all the components of a story, including 
characters, objects, concepts and locations, and to attach them to 
chapters and scenes in a way that facilitates the story-writing component 
of authoring.  I wrote this application to scratch an itch I had for free 
(as in beer and as in freedom) novel writing software for Linux.

The pure python version of plotdb is v.0.3.  This sounds extremely low, 
like pre-alpha, but the application began existence in the early fall of 
2007 using a different database engine.  Recently, I decided to move to 
sqlite as the database back end, which is supported as a native module in 
python 2.5.x.  The first release of the version written in pure python was 
dated 4/30/2008.

I have used the original version of this software extensively since it's 
initial incarnation in August of 2007.  I have used this pure python 
version since I ported it to sqlite.  There is no real difference that I 
can see in the two versions, except the pure python version is easier to 
maintain, albeit slightly slower.  I would consider this beta quality 
software, tested somewhat in real usage but not full production yet.  I am 
currently writing a novel and use this software daily for that purpose.

I, David May, am the sole party of blame in the production of this 
application.  It was conceived and written by me from scratch.  You can 
get plotdb with my compliments at:

http://w3.cnm.edu/~dmay/plotdb.html

plotdb is released under GPL v.2.  I am willing, as time permits, to 
incorporate changes made by users into the application.  I am particularly 
interested in portability changes that allow plotdb to be used on Windows 
or Mac, since I use Linux almost exclusively.  You can contact me at

dmay at cnm dot edu

If this is not the correct forum to announce this software, please accept 
my apologies in advance.  And thanks in advance for any direction anyone 
can provide on where else this should be posted to capture the largest 
audience of interest.  I do not lurk this list, so please respond to my 
email as well as (or in lieu of) posting to the list.

Kind regards,

David F. May

Subject: pybonjour 1.1.1 now available
Message-ID: <6A11FAF0-2E96-4C10-B664-322482C5782C@csail.mit.edu>

pybonjour 1.1.1 is now available for download at

   http://o2s.csail.mit.edu/download/pybonjour/

pybonjour provides a pure-Python interface (via ctypes) to Apple
Bonjour and compatible DNS-SD libraries (such as Avahi).  It allows
Python scripts to take advantage of Zero Configuration Networking
(Zeroconf) to register, discover, and resolve services on both local
and wide-area networks.  Since pybonjour is implemented in pure
Python, scripts that use it can easily be ported to Mac OS X, Windows,
Linux, and other systems that run Bonjour.

pybonjour 1.1.1 includes the following changes:

* All DNS-SD API calls are now made after acquiring a global lock
   object.  This object is a dummy (i.e. acquire() and release() do
   nothing), except in the case where pybonjour is using Avahi's
   Bonjour compatibility layer, in which case the lock is a
   threading.RLock instance.  This is necessary because the
   compatibility layer is not thread safe.

* Added browse_resolve_query.py to examples

For more information, see

Hash: SHA1

On behalf of the Python development team and the Python community, I  
am happy to announce the third alpha release of Python 2.6, and the  
fifth alpha release of Python 3.0.

Please note that these are alpha releases, and as such are not  
suitable for production environments.  We continue to strive for a  
high degree of quality, but there are still some known problems and  
the feature sets have not been finalized.  These alphas are being  
released to solicit feedback and hopefully discover bugs, as well as  
allowing you to determine how changes in 2.6 and 3.0 might impact
you.  If you find things broken or incorrect, please submit a bug  
report at

    http://bugs.python.org

For more information and downloadable distributions, see the Python
2.6 website:

    http://www.python.org/download/releases/2.6/

and the Python 3.0 web site:

    http://www.python.org/download/releases/3.0/

These are the last planned alphas for both versions.  If all goes  
well, next month will see the first beta releases of both, which will  
also signal feature freeze.  Two beta releases are planned, with the  
final releases scheduled for September 3, 2008.

See PEP 361 for release details:

Subject: Paver 0.7: Better than distutils, better docs and more
Message-ID: <B109E037-7466-4AC7-84D1-1B8F6731459F@gmail.com>

Paver (http://www.blueskyonmars.com/projects/paver/) is a "task"  
oriented build, distribution and deployment scripting tool. It's  
similar in idea to Rake, but is geared toward Python projects and  
takes advantage of popular Python tools and libraries.

Paver can be seen as providing an easier and more cohesive way to work  
with a variety of proven tools.

With Version 0.7, Paver is now a full stand-in for the traditional  
distutils- or setuptools-based setup.py. Need to perform some extra  
work before an sdist runs? No problem:

@task
def sdist():
     ...move files around, etc....
     call_task("distutils.command.sdist")

You put that in your pavement.py file and now running "paver sdist"  
will perform your logic and then run the distutils sdist command.

Paver can even generate a setup.py so "python setup.py sdist" or  
"python setup.py install" work just as they always have. And to make  
it easier for people who don't yet have Paver, you can include a small  
zip file that enables "python setup.py install" to work off of a  
pavement.py file even without Paver.

Paver 0.7 has a bunch of new tools to help with project documentation  
(taking advantage of Georg Brandl's Sphinx and also including Ned  
Batchelder's Cog). Paver now includes much better docs, too.

Message-ID: <68ii8sF2t3evdU1@mid.individual.net>

Pyrex 0.9.7 is now available:

   http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/

Highlights of this version:

* I have streamlined the integer for-loop syntax. Instead
   of the loop variable redundantly appearing in two places,
   it's now just

     for x < i < y:
       ...

* If you declare a variable as a list or dict, then calls
   to some of its methods will be compiled into type-specific
   Python API calls instead of generic ones.

* Most built-in constants are referenced directly instead of
   via dict lookup.

* There are two new builtin functions, typecheck() and
   issubtype(), for checking the types of arguments more safely
   (since isinstance and issubclass can be fooled).

What is Pyrex?
--------------

Pyrex is a language for writing Python extension modules.
It lets you freely mix operations on Python and C data, with
all Python reference counting and error checking handled
automatically.

Subject: [ANN] Release 0.70.0 of Task Coach
Message-ID: <67dd1f930805121314n499102b1r176bbccce860b0a5@mail.gmail.com>

Hi,

I'm happy to announce release 0.69.2 of Task Coach. This release
contains small feature enhancements, more translations and several bug
fixes. Task Coach is now distributed under the GPLv3+.

Bugs fixed:

* Allow for editing seconds in effort editor.
* The combobox in the effort detail editor always picked the first
task when multiple tasks had the same subject, effectively prohibiting
the user to move an effort record to another task with the same
subject.
* Reset invalid input in the priority field of the task editor to 0
instead of to the minimum priority (a large negative value).
* "View->Filter->Reset all filters" now also unchecks all categories.
* Task Coach now is packaged as a proper Debian package, thanks to
Stani Michiels. The Debian package installs a menu item for Task Coach
in the Applications/Office menu.

Features added:

* Paths to file attachments may be relative.
* Monthly and yearly recurrence of tasks.
* Added and reorganized keyboard short cuts.
* Start tracking effort for any active task using the system tray icon
right-click menu.
* Added a largely complete Ukranian translation thanks to Vitovt and
incomplete Finnish, Greek, Persian and Thai translations.

Feature changed:

* Slightly higher preference window so all icons fit and no scrolling is needed.

Dependencies changed:

* Task Coach now uses Subversion for version control. See
http://sourceforge.net/svn/?group_id=130831. This only affects you if
you want to develop or use Task Coach source code.
* Task Coach is now distributed under the GNU General Public License
version 3 or (at your option) any later version. This only affects you
if you want to distribute changed versions of Task Coach or want to
include source code from Task Coach in other software.


What is Task Coach?

Task Coach is a simple task manager that allows for hierarchical
tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is
developed using Python and wxPython. You can download Task Coach from:

http://www.taskcoach.org

In addition to the source distribution, packaged distributions are
available for Windows XP/Vista, Mac OS X, and Linux (Debian and RPM format).

Note that Task Coach is alpha software, meaning that it is wise to back
up your task file regularly, and especially when upgrading to a new release.

Cheers, Frank

What is pdfposter?
--------------------

Scale and tile PDF images/pages to print on multiple pages.

``Pdfposter`` can be used to create a large poster by building it from
multple pages and/or printing it on large media. It expects as input a
PDF file, normally printing on a single page. The output is again a
PDF file, maybe containing multiple pages together building the
poster.
The input page will be scaled to obtain the desired size.

This is much like ``poster`` does for Postscript files, but working
with PDF. Since sometimes poster does not like your files converted
from PDF. :-) Indeed ``pdfposter`` was inspired by ``poster``.

For more information please refere to the manpage or visit
the `project homepage <http://pdfposter.origo.ethz.ch/>`_.

Pyrex 0.9.8.1 is now available:

   http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/

Base classes no longer need to be specified in a forward
declaration of an extension type, or in the implementation
part of an extension type defined in a .pxd file.

Also, I've come up with an even better way of handling
circular cimports involving structs, unions and extension
types. You can now say things like

   from spam import struct Foo, union Blarg, class Ham

This simultaneously imports the name and forward-declares
it in the other module.

Pyrex is a language for writing Python extension modules.
It lets you freely mix operations on Python and C data, with
all Python reference counting and error checking handled

Subject: ANN: Python and Plone Boot Camps in Chapel Hill, NC
Message-ID: <4831BA98.1060207@unc.edu>

Triangle (NC) Zope and Python Users Group (TriZPUG) is proud to open 
registration for our fourth annual ultra-low cost Plone and Python 
training camps, BootCampArama 2008:

http://trizpug.org/boot-camp/2008/

Registration is now open for:

PyCamp: Python Boot Camp, August 4 - 8

Plone Boot Camp: Customizing Plone, July 28 - August 1

Advanced Plone Boot Camp: Plone 3 Techniques, August 4 - 8

All of these take place on the campus of the University of North 
Carolina at Chapel Hill in state of the art high tech classrooms, with 
free mass transit, low-cost accommodations with free wireless, and 
convenient dining options.

Plone Boot Camp is taught by Joel Burton, twice chair of the Plone 
Foundation. Joel has logged more the 200 days at the head of Plone 
classrooms on four continents. See plonebootcamps.com for dozens of 
testimonials from Joel's students.

PyCamp is taught by Chris Calloway, facilitator for TriZPUG and 
application analyst for the Southeast Coastal Ocean Observing System. 
Chris has developed PyCamp for over 1500 hours on behalf of Python user 
groups. Early bird registration runs through June 30. So register today!

PyCamp is TriZPUG's Python Boot Camp, which takes a programmer familiar 
with basic programming concepts to the status of Python developer with 
one week of training. If you have previous scripting or programming 
experience and want to step into Python programming as quickly and 
painlessly as possible, this boot camp is for you. PyCamp is also the 
perfect follow-on to Plone Boot Camp: Customizing Plone the previous week.

At Plone Boot Camp: Customizing Plone you will learn the essentials you 
need to build your Plone site and deploy it. This course is the most 
popular in the Plone world--for a good reason: it teaches you practical 
skills in a friendly, hands-on format. This bootcamp is aimed at:
     * people with HTML or web design experience
     * people with some or no Python experience
     * people with some or no Zope/Plone experience
It covers using Plone, customizing, and deploying Plone sites.

At Advanced Plone Boot Camp: Plone 3 Techniques you will learn to build 
a site using the best practices of Plone 3 as well as advance your 
skills in scripting and developing for Plone. The course covers the new 
technologies in Plone 3.0 and 3.1 intended for site integrators and 
developers: our new portlet infrastructure, viewlets, versioning, and a 
friendly introduction to Zope 3 component architecture. Now, updated for 
Plone 3.1! The course is intended for people who have experience with 
the basics of Plone site development and HTML/CSS. It will cover what 
you need to know to take advantage of these new technologies in Plone 3.

Subject: MDP: A Simple Feed Forward Network
Message-ID: <1e6a9bd9-d928-4efc-bfae-09f2dc1cfacf@i76g2000hsf.googlegroups.com>

Hey everyone,
  I was hoping to see some people out on the python list that are
familiar with MDP (Modular Toolkit for Data Processing -
http://mdp-toolkit.sourceforge.net/)?

  I am wanting to develop a very simple feed forward network.  This
network would consist of a few input neurons, some hidden neurons, and
a few output neurons.  There is no learning involved.  This network is
being used as a gene selection network in a genetic simulator where we
are evolving the weights and connectivity.

  There are many different types of nodes listed as being supported,
but i can't figure out the best one to use for this case.  In this
situation, we only want to iterate through the network X times.  (In
the simples version, with no cycles, this would mean that once the
output nodes are calculated there would be no additional calculations
since the system would be stable and non-learning).  Node types are
listed at the bottom here: http://mdp-toolkit.sourceforge.net/tutorial.html#quick-start

  In the more complex version, we would have the same model but
instead of having straight connectivity all the way through, we would
add a few cycles in the hidden layer so that a few neurons would feed
back into themselves on the next time step.  This could also be
connected to a 'selector' layer, that feeds back on the hidden layer
as well.  Since we are only running this a finite number of times, the
system would not spiral out into instability.

  Any suggestions for which node types to use, or possibly what other
libraries would be helpful? I realize that due to the relative
simplicity of this network I could hand code this from scratch.  MDP
just looks extremely handy and efficient and I'd like to use it if
possible.

Simple Network:

(H is interconnected fully with the Input and Output layer)
I -> H -> O
I -> H -> O
I -> H -> O

Cycled Network (Trying to show that the first hidden neuron is
connected back to itself)
     v---|
I -> H -> O
I -> H -> O
I -> H -> O

Complex Network (Trying to show that the first hidden neuron is
connected to another hidden neuron S that connects back to the input
of H.  S would be interconnected with the other hidden neurons as
well)
         v--- S <--|
I ->    H         -> O
I ->    H         -> O
I ->    H         -> O

Thanks!

The healthcare sector is a very complex information management space.
Healthcare IT applications are notorious for their lack of real
interoperability.  This of course increases the overall healthcare costs
due to lost and/or missing information.  

While the rate of adoption of IT in direct patient care scenarios has
been slow in the past; it is expected to increase dramatically over the
next few years.  A recent study shows that there will be a demand for an
additional 40,000+ healthcare information technology workers IN THE US
alone: http://medir.ohsu.edu/~hersh/hit-workforce-hersh.pdf 

The current situation for funding healthcare IT projects is that
agencies will have a specific healthcare information management need and
can only fund for that project. Examples are; a diabetes registry or an
AIDS treatment tracking application.  The result is that they get the
application that fills that need but the information is in a specific
format for that project and is, more often than not, incapable of being
shared with any semantic meaning with any other application.  Can the
business of healthcare IT continue in this way?

While there has been much work done over the last 40 years on healthcare
IT standards, we still aren't ahead of the game on any major scale.  
However, a core group of people have been working for almost two decades
with a primary principle of 'implementation'.  Basically, if it can't be
implemented then it doesn't work. A history of their research and
development efforts is worth the quick read:
http://www.openehr.org/about/origins.html 


Implementation is already proven in an opensource Eiffel reference
implementation as well as an opensource Java implementation of the
Reference Model.  There is also a significant C# commercial
implementation by Ocean Informatics
http://oceaninformatics.biz/CMS/index.php 

These are complimented with various opensource tools for working in this
environment (see the Software link at http://www.openehr.org ).

The Python/Zope/Plone community will be very familiar with the concepts
of two-level modeling that is represented in the openEHR specifications:
http://www.openehr.org/releases/1.0.1/roadmap.html In a nutshell, the
openEHR specs. define a very broad, core reference model, that is
constrained by a knowledge model (called archetypes).  Any
implementation of the reference model knows how to deal with the
structure of an archetype and therefore information expressed in an
archetype instance can be exchanged between applications.  

These specifications are becoming more and more widely known. In fact,
the Archetype Definition Language (ADL) is now part of a CEN (European)
health record standard and is an ISO candidate. 

As you may have noticed, there is a non-profit foundation established to
care for the IP and insure that it is and always will be open. The
openEHR Foundation is open to membership by other organizations. In
fact, the Python or Zope foundations could easily become an influential
member. There are also governance processes in place to vet the changes
in the specifications.

The project that I am announcing is the Open Source Health Information
Platform (OSHIP).  I (as others) have tinkered with Python/Zope/Plone
over the past several years in healthcare applications.  These have met
with mixed results mostly due to the same problem; lack of
interoperability (search SourceForge for more info).  

The concept of OSHIP is that it can be an application framework for
interoperable healthcare applications.  This should be especially
appealing to governments and funding agencies worldwide. OSHIP operation
is envisioned as taking the archetypes expressed in ADL and store them
in an Archetype Repository as Python objects.  These instances are then
available to developers to use in healthcare applications.  Knowledge
workers can create/edit the ADL files (using existing opensource tools)
to create whatever knowledge model may be needed for a specific
application.

The current state of OSHIP is that I have entered the specifications as
ZCA interfaces and basic implementations.  But as I said, I am a
'tinkerer'.  I need your help in evaluating this basic implementation
and fleshing out the classes according to the specifications.  

The functioning components already include a parser for the ADL files
and an (almost complete) object builder to store these in the ZODB for
use by OSHIP users. 

While I am now appealing to the broader Python/Zope communities for
participation.  There is already interest in OSHIP.  There is a workshop
scheduled ( http://www.oshipworkshop.if.uff.br )for July 21, 2008 where
we will be spending 10 days on health informatics, openEHR and OSHIP.
The goal is to actually develop one or more OSHIP applications as
examples.  There is at least one PhD student that is using these ideas
for his project.  OSHIP is already considered to be the Python reference
implementation of the openEHR specs.  (BTW: for anyone interested there
is a Ruby implementation underway as well).

In order to promote the widest use of the openEHR specifications; OSHIP
is licensed under the Mozilla tri-license
http://www.mozilla.org/MPL/boilerplate-1.1/mpl-tri-license-txt

If you have any interest in helping move this project ahead please join
the developer's list at the SourceForge Project site:
http://sourceforge.net/projects/oship

The sourcecode will be placed on the openehr.org SVN server by 31 May,
2008. I also plan to put an egg on the SF site.  This will be 'alpha'
level code, though I hope that we can move to a beta stage at a fairly
rapid pace (mid July?). I do not envision that the Zope experts will
need to do the actual manual labor of fixing a lot of this code. If I
can get some helpful suggestions then I will gladly do the work as well
as manage others helping out.  

As an aside, one of the key benefits to this project is that the core
documentation is already complete.  The openEHR specifications do that
for us.  We just need to finish the implementation and some top-level
ZCA specific docs. 

Thank you very much for your kind attention to this project that holds
such a deep passion for me.

Sincerely,
--Tim Cook

Subject: [pygtk] ANNOUNCE: PyGObject 2.14.2
Message-ID: <4836F917.6080609@async.com.br>

I am pleased to announce version 2.14.2 of the Python bindings for GObject.

The new release is available from ftp.gnome.org as and its mirrors
as soon as its synced correctly:

   http://download.gnome.org/sources/pygobject/2.14/

What's new since PyGObject 2.14.1:
     - Allow gobject.property work with subclasses. (#523352, Tomeu Vizoso)
     - Unbreak Source.prepare (#523075, Bryan Silverthorn)
     - Never override customly set 'tp_new' and 'tp_alloc' (Paul Pogonyshev)
     - Don't link against libffi if we cannot find libffi
       on the system. (#496006, Ed Catmur)
     - Dist .m4 files. (#496011, Ed Catmur)
     - Don't return NULL after warning of enum comparsion
       (#519631, Paul Pogonyshev)

Blurb:

GObject is a object system library used by GTK+ and GStreamer.

PyGObject provides a convenient wrapper for the GObject+ library for use
in Python programs, and takes care of many of the boring details such as
managing memory and type casting.  When combined with PyGTK, PyORBit and
gnome-python, it can be used to write full featured Gnome applications.

Like the GObject library itself PyGObject is licensed under the
GNU LGPL, so is suitable for use in both free software and proprietary
applications.  It is already in use in many applications ranging
from small single purpose scripts up to large full
featured applications.

PyGObject requires GObject >= 2.8.0 and Python >= 2.3.5 to build.

Message-ID: <87y75u2ukh.fsf@hbox.dyndns.org>

On behalf of the VIFF Development Team, I am happy to announce the
release of VIFF version 0.6:

  Tar/GZ:  http://viff.dk/release/viff-0.6.tar.gz
  Tar/BZ2: http://viff.dk/release/viff-0.6.tar.bz2
  Zip:     http://viff.dk/release/viff-0.6.zip
  Exe:     http://viff.dk/release/viff-0.6.win32.exe

Changes since VIFF 0.5:

  The average time for a secure comparison was reduced by 60-70%.
  Comparisons now work with an actively secure multiplication protocol.
  A memory leak was fixed. Converted documentation to new Sphinx format,
  please see: http://viff.dk/doc/index.html

About VIFF:

  Virtual Ideal Functionality Framework is a framework for creating
  efficient and secure multi-party computations (SMPC). Players, who do
  not trust each other, participate in a joint computation based on
  their private inputs. The computation is done using a cryptographic
  protocol which allows them to obtain a correct answer without
  revealing their inputs -- even when some players try to cheat.
  Operations supported include addition, multiplication, and comparison,
  all with Shamir secret shared outputs.

==================
This release fixes a major RFC 1350 compliance problem with the remote TID.

About Release 0.2:
==================
This release adds variable block sizes, and general option support,
implementing RFCs 2347 and 2348. This is accessible in the TftpClient
class via the options dict, or in the sample client via the --blocksize
option.

About Release 0.1:
==================

This is an initial release in the spirit of "release early, release
often". Currently the sample client works, supporting RFC 1350. The
server is not yet implemented, and RFC 2347 and 2348 support (variable
block sizes) is underway, planned for 0.2.

About Tftpy:
============

Purpose:
--------
Tftpy is a TFTP library for the Python programming language. It includes
client and server classes, with sample implementations. Hooks are
included for easy inclusion in a UI for populating progress indicators.
It supports RFCs 1350, 2347 and 2348.

	Reminder
Message-ID: <200805282037.18482.paul@boddie.org.uk>

First of all, a reminder to those of you considering registering for 
EuroPython 2008, held in Vilnius, Lithuania from 7th to 12th July (talks from 
7th to 9th, sprints from 10th to 12th): the early registration deadline is on 
Saturday 31st May, and if you would like to take advantage of the reduced 
registration fee, now is the time to navigate to the EuroPython site and to 
make your registration:

http://www.europython.org/Registration

For the impatient, here's a link to the registration form itself:

http://registration.europython.eu/

Talk Submissions Period Extended
--------------------------------

The original deadline for submitting talk proposals for EuroPython 2008 passed 
on Thursday 22nd May, and although there have been quite a few submissions, 
the EuroPython organisers would like to encourage a few more! So, we have now 
decided to give all potential submitters some more time to put together 
proposals and send them in for consideration.

What this means is that anyone who had considered making a talk proposal but 
then found themselves short of time before last Thursday can now aim for the 
new deadline of Monday 2nd June - there's even a weekend before the deadline 
for anyone needing "quiet time" to sketch out their proposal! As always, the 
EuroPython organisers realise that the deadlines we've set aren't always 
compatible with everyone's personal schedule.

Remember that we're only looking for proposals at this point, not the entire 
talk or materials, although we obviously expect those things to be ready for 
the conference. ;-)

Take a look at the Call for Participation for all the details:

http://www.europython.org/CallForParticipation

Or go straight to the page for talk submissions:

http://www.europython.org/Talk_Submissions

We look forward to seeing your proposals and hopefully seeing you in Vilnius!

Message-ID: <c7009a550805291511t235b84a9xed01d26a222904d5@mail.gmail.com>

I'm pleased to announce the release of NumPy 1.1.0.

NumPy is the fundamental package needed for scientific computing with
Python.  It contains:

 * a powerful N-dimensional array object
 * sophisticated (broadcasting) functions
 * basic linear algebra functions
 * basic Fourier transforms
 * sophisticated random number capabilities
 * tools for integrating Fortran code.

Besides it's obvious scientific uses, NumPy can also be used as an
efficient multi-dimensional container of generic data. Arbitrary
data-types can be defined. This allows NumPy to seamlessly and
speedily integrate with a wide-variety of databases.

This is the first minor release since the 1.0 release in
October 2006. There are a few major changes, which introduce
some minor API breakage. In addition this release includes
tremendous improvements in terms of bug-fixing, testing, and
documentation.

For information, please see the release notes:
http://sourceforge.net/project/shownotes.php?release_id=602575&group_id=1369

Thank you to everybody who contributed to this release.

Enjoy,

The wiki announcing the initial source code release of OSHIP is
available at: 
http://www.openehr.org/wiki/display/dev/Python+developer%27s+page 

Including links to installation and initial startup. 

There is a news release on Linux Medical News that contains more
background and project justification information:
http://linuxmednews.com/1212171292/index_html 

I am inviting expert discussion on the circular import issues due to the
desire to adhere as closely to the openEHR specifications as possible.
The issues are in the interfaces being implemented with schema types
that are the same or at least in the same packages as the
implementations of those classes.

Thanks for your comments.

Message-ID: <484182EB.4020102@python-academy.de>

Greetings,

I'm pleased to announce that the program for the first-annual
EuroSciPy Conference is now available at:

http://scipy.org/EuroSciPy2008#schedule

http://scipy.org/EuroSciPy2008#courses


About EuroSciPy
---------------
EuroSciPy is designed to complement the popular SciPy
Conferences which have been held for the last 7 years at
Caltech (the 2008 SciPy Conference in the U.S. will be held
the week of August 19-24). Similarly, the EuroSciPy Conference
provides a unique opportunity to learn and affect what is
happening in the realm of scientific computing with Python.
Attendees will have the opportunity to review the available
tools and how they apply to specific problems.
By providing a forum for developers to share their Python
expertise with the wider commercial, academic, and research
communities, this conference fosters collaboration and
facilitates the sharing of software components, techniques and
a vision for high level language use in scientific computing.
Typical presentations include general python use in the
sciences, as well as NumPy and SciPy usage for general problem
solving.  Beyond the excellent talks, there are inter-
session discussions that prove stimulating and helpful.
Registration will include breakfast, snacks and lunch for
Saturday and Sunday.

Please pass this announcement along to any other relevant
contacts.

Many Thanks,
Mike M?ller

QOTW:  "GHUM:  There are no big applications written in Python.

GHUM:  Big applications are written in JAVA or COBOL or C# or other legacy
programming systems.

GHUM:  If you programm in Python, your applications become quite small. Only
frameworks in Python are big.

JMC:  So the fact that there are no big applications written in Python IS the
success story." - Harald Armin Massa and D'Arcy J.M. Cain
