Subject: Bruce The Presentation Tool, release 1.2
Message-ID: <200701021719.10251.anthony@interlink.com.au>

Bruce the Presentation Tool is for Python programmers who are tired 
of fighting with presentation tools. In its basic form it allows 
text, code or image pages and even interactive Python sessions. It 
uses PyGame and is easily extensible to add new page types.

Changes in 1.2:

    * added control-F to switch between fullscreen and windowed mode 
      (X11 only)
    * added ShellInterpreterPage and SpawnPage
    * added socrates.py driver script - see doc/socrates.txt 
      for more
    * many, many new features added - highlighting of code pages, 
      timed auto-advancing of pages, simple syntax for text page 
      effects, autotyping enhancements... and much more. See 
      doc/socrates.txt for more.

It runs on Unix, MacOS and Windows, and requires pygame.

You can get Bruce from the cheeseshop: 
http://cheeseshop.python.org/pypi/bruce

Example presentations (the ones I presented at OSDC a month ago) can 
be seen at

Message-ID: <1167810602.380286.43030@n51g2000cwc.googlegroups.com>

PyDbLite is a small, fast, pure-Python, in-memory database management
program

The database object supports the iterator protocol, so that requests
can be expressed with list comprehensions or generator expressions
instead of SQL. The equivalent of :

    cursor.execute("SELECT name FROM table WHERE age=30")
    rows = cursor.fetchall()

is :

    rows = [ row["name"] for row in table if row["age"] == 30 ]

Data is stored on disk in a single cPickled file. Records are indexed
by a unique record identifier, that can be used for direct access.
Since operations are processed in memory they are extremely fast,
nearly as fast as SQLite in the few tests I made. An index can be
created on a field to speed up selections

taylayout 00.00.10

http://cheeseshop.python.org/pypi/taylayout/00.00.10

Layout and Controls helpers for rapid and dynamic IronPython WinForms
GUIs.
TayLayout is a more sophisticated version of the flow layout - you can
add controls to a panel or form and it takes care of positioning them.
Controls are added in a Left to Right order until you specify that a
new line is required.

TayLayout also has a set of convenience functions to quickly build up a
functional interface. Controls can be added and configured in the
layout with a single line of code. Once the layout is complete the form
is sized to match the number of controls. TayLayout therefore suits
dynamic applications or for rapid prototyping.

This is an early release for developer feedback. 2 sample applications
are supplied.

New in this release
===================

* The add_argument method now allows a positional argument with
nargs='*' to specify a default value::

    >>> parser = argparse.ArgumentParser()
    >>> parser.add_argument('foo', nargs='*', default=['def'])
    >>> parser.parse_args('1 2 3'.split())
    Namespace(foo=['1', '2', '3'])
    >>> parser.parse_args([])
    Namespace(foo=['def'])

About argparse
==============

The argparse module is an optparse-inspired command line parser that
improves on optparse by:

* handling both optional and positional arguments
* supporting parsers that dispatch to sub-parsers
* producing more informative usage messages
* supporting actions that consume any number of command-line args
* allowing types and actions to be specified with simple callables
instead of hacking class attributes like STORE_ACTIONS or
CHECK_METHODS

as well as including a number of other more minor improvements on the
optparse API. To whet your appetite, here's a simple program that sums
its command-line arguments and writes them to a file::

   parser = argparse.ArgumentParser()
   parser.add_argument('integers', type=int, nargs='+')
   parser.add_argument('--log', type='outfile', default=sys.stdout)
   args = parser.parse_args()
   args.log.write('%s\n' % sum(args.integers))
   args.log.close()

Subject: PyCon 2007 Funding Available
Message-ID: <459DCD62.60004@python.org>

The Python Software Foundation has allocated some funds to help people
attend PyCon 2007.  If you'd like to come to PyCon but can't afford
it, maybe the PSF can help you.  The funding can cover any or all of:

* Your registration for PyCon
* Your hotel room at the conference hotel
* Your flight or other transportation

To apply, send e-mail to <pycon at python.org>.  Please state your
name, location, and what you would like to have funded.  If you want
assistance with your transportation costs, please provide a rough
estimate (say, to the nearest US$100) of how much a round-trip will
cost.

You should also say why you should come to PyCon, and what you'll be
doing.  We don't need an essay, but please provide a few sentences of
explanation.  Priority will be given to people who can contribute
significantly to PyCon or to Python, e.g. students working on a task,
conference speakers, sprint leaders or developers critical to a
sprint, or people doing public service work with Python.

Messages must be received by January 19 2007.  Upon receiving your
message, we'll send you a notice of receipt.  The PSF's Conference
Committee and I will discuss the applications and allocate funding to
a subset of the applicants.  You should be notified of
acceptance/rejection by January 28 2007.

Cost notes: PyCon registration is US$195. Hotel rooms are around
$90/night; about $300 for the duration of the conference, $700 for
conference + sprints.  The hotel cost can be lower if you find someone
(or two or three) to share a room with; this is encouraged.  The PSF
can't cover your meals during the conference, or registration fees for
tutorials.

We will try to maximize the benefit of the funding, so three people
who need small amounts are more likely to be funded than one person
who needs a large amount.  To improve your chances, please try to
request the minimum amount of funding you need to attend PyCon.

Subject: ANN: Amara XML Toolkit 1.2.0.1
Message-ID: <459EB8B0.2050804@ogbuji.net>

Amara 1.2 was released to Cheeseshop New Year's Eve, but in all the
festivities and travel I forgot the announcements.  Just as well because
I'd forgotten to include a minor fix, and so here is 1.2.0.1.

http://uche.ogbuji.net/tech/4suite/amara
http://cheeseshop.python.org/pypi/Amara/
ftp://ftp.4suite.org/pub/Amara/

Changes since Amara 1.1.9:

* Add omit_nodetype_rule bindery rule
* Add force_nsdecls parameter to bindery node xml() method
* 4Suite 1.0 compatibility (requires 4Suite 1.0.2, in fact)
* Add support for attribute patterns to pushdom/pushbind
* Add experimental (not very reliable) xml_xslt() method to bindery object
  to apply transforms
* Improvements to trimxml command line
* Turn off DTD validation by default
* Add support for DTD validation & custom binding classes to convenience APIs
* Add custom binding demo
* Updates to the manual
* Bug fixes

Amara XML Toolkit is a collection of Python tools for XML processing--
not just tools that happen to be written in Python, but tools built from
the ground up to use Python's conventions and take advantage of the many
advantages of the language.

Amara builds on 4Suite [http://4Suite.org], but whereas 4Suite offers
more on literal implementation of XML standards in Python, Amara
focuses on Pythonic idiom.  It provides tools you can trust to conform
with XML standards without losing the familiar Python feel.

The components of Amara are:

* Bindery: data binding tool (a very Pythonic XML API)
* Scimitar: implementation of the ISO Schematron schema language for
            XML; converts Schematron files to Python scripts
* domtools: set of tools to augment Python DOMs
* saxtools: set of tools to make SAX easier to use in Python
* Flextyper: user-defined datatypes in Python for XML processing

There's a lot in Amara, but here are highlights:

Amara Bindery: XML as easy as py
--------------------------------

Bindery reads an XML document and it returns a data structure of
Python objects corresponding to the vocabulary used in the XML document,
for maximum clarity.

Bindery turns the document

    <monty>
      <python spam="eggs">What do you mean "bleh"</python>
      <python ministry="abuse">But I was looking for argument</python>
    </monty>

Would become a set of objects so that you could write

binding.monty.python.spam

In order to get the value "eggs" (as a Python Unicode object) or 

    binding.monty.python[1]

In order to get the element object with the contents "But I was looking for argument". 

There are other such tools for Python, and what makes Bindery unique is
that it's driven by a very declarative rules-based system for binding
XML to the Python data.  You can register rules that are triggered by
XPattern expressions specialized binding behavior.  It includes XPath
support and is very efficient, using SAX to generate bindings.

See the user documentation, manual.html, for more details.

Scimitar: exceptional schema language for an exceptional programming language
-----------------------------------------------------------------------------

Scimitar is an implementation of ISO Schematron that compiles a Schematron
schema into a Python validator script.  You typically use scimitar in two
phases.  Say you have a schematron schema schema1.stron and you want to
validate multiple XML files against it, instance1.xml, instance2.xml,
instance3.xml.

First you run schema1.stron through the scimitar compiler script,
scimitar.py:

scimitar.py schema1.stron

A file, schema1-stron.py, is generated in the current working directory.
If you'd prefer a different location or file name, use the "-o" option.
The generated file is a validator script in Python.  It checks the
schematron rules specified in schema1.stron.

Run this validator on each XML file you wish to validate:

python schema1.py instance1.xml

The validation report is generated on standard output by default, or you
can use the "-o" option to redirect it to a file.

The validation report is an XML external parsed entity, a format much like
a well-formed XML document, but with some restrictions relaxed.

Amara DOM Tools: giving DOM a more Pythonic face
------------------------------------------------

Amara DOM Tools features pushdom, similar to xml.dom.pulldom, but easier
to use, and a function to return an XPath location for any DOM node.

Amara SAX Tools: SAX without the brain explosion
------------------------------------------------

Tenorsax (amara.saxtools.tenorsax) is a framework for "linerarizing" SAX logic
so it flows a bit more naturally, needing much less state machine wizardry.

License
-------

Amara is open source, provided under the 4Suite variant of the Apache
license.  See the file COPYING for details.

Installation
------------

Amara requires Python 2.4 or more recent and 4Suite-XML 1.0 or more
recent.  The easiest way to install it is:

easy_install amara

If this does not work you are probably not set up for easy_install and I
suggest you follow the simple instructions at

http://peak.telecommunity.com/DevCenter/EasyInstall

easy_install will automatically take care of installing dependencies for
you.  If you prefer not to use easy_install, grab a 4Suite-XML package more
recent than 1.0 and install that, then install the Amara package
using the usual:

python setup.py install

Or a Windows installer, or other method.

Subject: FlightFeather Social Networking Platform, Release 0.2.6
Message-ID: <20070106015047.GA4392@localhost>

FlightFeather's goal is "social networking for everyone".  This means
that *anyone* should have a chance to run a *popular* social
networking site -- on minimal hardware, and without wasting bandwidth.

Release 0.2.6 fixes a bug, which could cause the FlightFeather server
to hang if excessively long words appeared in posts or comments.  You
can download this release (free/open source under the GPL) from the
"BoSStats" site, which runs on FlightFeather.

     http://www.bosstats.com/flightfeather.html


A Brief Overview of FlightFeather and BoSStats
----------------------------------------------
FlightFeather is in its early stages, but it is functional.  You can
see the system in action on the BoSStats site.  BoSStats is
dedicated to improving the world of work: you can discuss what makes a
good boss, or share your experiences of office politics. You can also
comment and vote on the posts made by others.  The application does
not set cookies, and no registration is required for anything except
voting.


     http://www.bosstats.com/


BoSStats is a good testbed for FlightFeather, and has value of its
own, since meaningful advice about work-related problems is very hard
to find.  A "Wisdom of Crowds" solution -- particularly with strong
privacy protection (see below) -- is a necessary addition to this
field.

FlightFeather's most important feature is that all write requests
generate (or modify) HTML files.  In consequence, a pure read (the
most common operation) merely serves static pages.

The major design focus for FlightFeather are responsiveness and
performance; the system should eventually support very high traffic
volumes.  In addition, FlightFeather allows for a great deal of user
privacy -- a critical, rapidly emerging problem in the social
networking realm.

But in order to make the panel a success we need some questions.  We
will have a portion of time open to questions from the floor, but we
would also like to have some questions lined up.  If you have any
questions you would like to have answered by the panel, please add them
to http://us.pycon.org/TX2007/PythonDevPanel .  The wiki page will be
considered the definitive location of collected questions so please do
not leave any questions as a reply to this announcement as it will not
get noticed.

I do not know if there will be an audio or video recording of the panel
discussion, but there is a decent chance if last year's PyCon is any
indication.  Plus someone in the audience might be kind enough to type
up a transcript and post it online.

Thanks in advance to anyone who contributes a question.

Hello everybody,

the next meeting of pyCologne, the Python User Group K?ln (Cologne), takes
place on:

Date: 10.01.2007
Time: 18:30 h
Location: Pool 0.14, computing centre (RRZK-B) of the University Cologne,
          Berrenrather Str. 136, 50937 K?ln


Detailed information can be found on our page in the German Python Wiki:

http://wiki.python.de/User_Group_K%C3%B6ln#Termine


We invite everybody in the area who's interested in the Python programming
language to join our meetings or take part in the discussions on our mailing list.

If you are planning to come to this meeting, it would be sensible, though not
strictly necessary, to drop us a line on our mailing list or via private email
to me (if you have not already done so), because the room we have at the
university has a limited capacity.

Looking forward to see many of you!

We'll be holding our regular PyGTA (Toronto Python User's Group) meeting 
on the third Tuesday of the month, January 16, 2007.  The topic will be 
the ctypes Foreign Function Interface system, which has been made a 
standard module in Python 2.5.  This library allows you to wrap C shared 
libraries using Python code without the need to compile an extension 
module.  It is the library being used in the PyOpenGL 3.x release, 
replacing the SWIG wrappers used for the 2.x release of the project.  
We'll cover what the library is, why and when you would want to use it, 
and a bit of how to use it for wrapping larger C libraries.  We'll also 
discuss a bit about the areas that aren't yet fully developed wrt use 
with larger libraries.

As usual, we'll be meeting at Linux Caffe at 6:30pm for socialisation, 
and we'll start the presentation at 7:00pm.  We normally head out for 
beers and more dessert between 8:30 and 9:00pm.  Linux Caffe is a great 
place to hang out and work, the have free WiFi, great coffee, pastries, 
chocolate (when they have it) and other assorted goodies.  They are 
located at the corner of Grace and Harbord Streets, one block South of 
Christie subway station.

PythonTidy cleans up, regularizes, and reformats the text of Python

It is released under the GNU General Public License.  This is the
first public release.

Python scripts are usually so good looking that no beautification is
required.  However, from time to time, it may be necessary to alter
the style to conform to changing standards.  This script converts
programs in a consistent way.  It abstracts the pretty presentation of
the symbolic code from the humdrum process of writing it and getting
it to work.

Subject: [ANN] Release 0.61.5 of Task Coach
Message-ID: <45A555EE.60302@niessink.com>

Hi all,

Release 0.61.5 of Task Coach is a bug-fix release that hopefully fixes
the following bug that was introduced in release 0.61.4:

* Opening a Task Coach file with many effort records is slow. Opening an 
edit dialog for a task with many effort records is slow too.


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
https://sourceforge.net/projects/taskcoach/

In addition to the source distribution, packaged distributions are
available for Windows XP, Mac OSX, 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

Subject: Twisted 2.5.0 released
Message-ID: <60ed19d40701110753x4a17fdb3kfde85f2c8d30b3c7@mail.gmail.com>

Get Twisted: http://twistedmatrix.com/

Twisted is an event-based framework for internet applications which
works on Python 2.3.x, 2.4.x, and 2.5.x.

Twisted 2.5.0 is a major feature release, with several interesting new
developments and a great number of bug fixes. Some of the highlights
follow.

 * AMP, the Asynchronous Messaging Protocol, was introduced.  AMP is a
protocol which provides request/response semantics over a persistent
connection in a very simple and extensible manner.

 * An Epoll-based reactor was added, which can be used with twistd or
trial by passing "-r epoll" on the command line. This may improve
performance of certain high-traffic network applications.

 * The 'twistd' command can now accept sub-commands which name an
application to run. For example, 'twistd web --path .' will start a
web server serving files out of the current directory. This
functionality is meant to replace the old way of doing things with
'mktap' and 'twistd -f'.

 * Python 2.5 is now supported. Previous releases of Twisted were
broken by changes in the release of Python 2.5.

 * 'inlineCallbacks' was added, which allows taking advantage of the
new 'yield' expression syntax in Python 2.5 to avoid writing callbacks
for Deferreds.

 * Many improvements were made to the Jabber support in twisted.words.

Hit http://twistedmatrix.com/trac/wiki/Downloads to see what's new and
to get the latest downloads, including tarballs and Windows
installers.

Again thanks to Jean-Paul Calderone and Cory Dodt for helping get this
release out the door, and thanks to all the Twisted contributors whose
work went into Twisted 2.5.

Subject: FlightFeather Social Networking Platform, Release 0.2.7
Message-ID: <20070111232543.GA21648@localhost>

FlightFeather's goal is "social networking for everyone".  This means
that *anyone* should have a chance to run a *popular* social
networking site -- on minimal hardware, and without wasting bandwidth.

Release 0.2.7 adds a complete working example site to the
distributions, along with directions on how to set it up.  You can
download this release (free/open source under the GPL) from the
"BoSStats" site, which runs on FlightFeather.

     http://www.bosstats.com/flightfeather.html

You are always welcome to participate in the discussion on the
"BoSStats" site; the topic covered (what makes a good boss, office
politics, etc.) is valuable in and of itself.  Please, however,
refrain from posting test comments, as the site is live.


A Brief Overview of FlightFeather and BoSStats
----------------------------------------------
FlightFeather is in its early stages, but it is functional.  You can
see the system in action on the BoSStats site.  BoSStats is
dedicated to improving the world of work: you can discuss what makes a
good boss, or share your experiences of office politics. You can also
comment and vote on the posts made by others.  The application does
not set cookies, and no registration is required for anything except
voting.


     http://www.bosstats.com/


BoSStats is a good testbed for FlightFeather, and has value of its
own, since meaningful advice about work-related problems is very hard
to find.  A "Wisdom of Crowds" solution -- particularly with strong
privacy protection (see below) -- is a necessary addition to this
field.

FlightFeather's most important feature is that all write requests
generate (or modify) HTML files.  In consequence, a pure read (the
most common operation) merely serves static pages.

The major design focus for FlightFeather are responsiveness and
performance; the system should eventually support very high traffic
volumes.  In addition, FlightFeather allows for a great deal of user
privacy -- a critical, rapidly emerging problem in the social
networking realm.

Construct, the "Parsing Made Fun" library, is proud to release
it's second revision!

More info and download at: http://construct.wikispaces.com/

Construct is a python library for parsing and building of
data structures (binary or textual). It is based on the concept of
defining data structures in a declarative manner,
rather than procedural code: more complex constructs are
composed of a hierarchy of simpler ones.

* For an elaborate example, see
http://construct.wikispaces.com/examples

* For more information, see the tutorial at

Subject: Mini-tutorials on the Zope component architecture and on zc.buildout
	at PyCon 
Message-ID: <66B7543D-5800-41D8-9977-204E8F812855@zope.com>

At PyCon:

   http://us.pycon.org/TX2007/HomePage

I'll be giving a tutorial that combines two separate mini-tutorials:

   http://us.pycon.org/TX2007/TutorialsAM#AM7

The first mini-tutorial is on the Zope Component Architecture.  The  
Zope Component Architecture, which isn't tied to the Zope Web  
application server, provides mechanisms for assembling, extending,  
and integrating applications using loosely-coupled parts. The  
tutorial will explain why one would want to use a component system,  
including when to and when *not* to use components.  It will provide  
a high-level introduction to the main features of the Zope component  
architecture, comparing it to other Python solutions to the same  
kinds of problems the Component Architecture addresses.

The second mini-tutorial provides an introduction to zc.buildout.   
zc.buildout is a system for automating the assembly and deployment of  
applications having many parts.  It also provides a mechanism for  
installing and assembling Python eggs in ways that are especially  
helpful during development and when creating larger applications.   
The tutorial will explain and show examples of using zc.buildout to

- Create a sandbox for experimenting with packages without installing  
them into a system Python.

- Create development environments for working on packages.

- Create system with multiple applications.

To get the most from zc.buildout requires some knowledge of using and  
creating eggs. The mini tutorial will provide a lazy programmer's  
introduction to using and creating eggs.

Subject: decorator 2.0 released
Message-ID: <1168685131.897353.274710@a75g2000cwd.googlegroups.com>

The aim of the decorator module it to simplify the usage of decorators
for the average programmer. Version 2.0 is a major release. From
the README:

Decorator module
---------------------------

Home page:
http://www.phyast.pitt.edu/~micheles/python/documentation.html

Dependencies:

The decorator module is intented for usage in Python 2.4 and above,
but it also works with limitated functionality in Python 2.3 and
possibily below.

Installation:

If you have ``easy_install``, just type ``easy_install decorator``,
else
unzip the distribution archive into a directory called "decorator"
in your Python path. For instance, on Unices you could give something
like that:

$ unzip decorator.zip -d decorator

Testing:

Just go in the package directory and give

$ python doctester.py documentation.txt

This will generate the _main.py file containing all the examples
discussed in the documentation, and will run the corresponding tests.

Backward compatibility
------------------------------------

The 2.0 release of the decorator module breaks backward compatibility
in
a few minor ways.

- now ``decorator`` fails setting the right name for the decorated
function
  when using Python 2.3. I judged that this was an acceptable price
  considering that Python 2.3 has become pretty old and that in any
case
  using decorators in Python 2.3 is uncommon.

- now the decorated function and the original function do not share the
  same attributes, the decorated function has just a copy of the
  original function attributes.

- now the utility function ``getinfo`` returns a different dictionary;

- the utility function ``newfunc`` has been removed; its functionality
has been
  subsumed into ``update_wrapper``.

Enjoy,

             Michele Simionato

=============
Announcements
=============

Some of you may know that Steven Bethard, having taken over the summaries from
Brett Cannon some time ago, is no longer able to keep up with them. After much
holiday stress and busy days, I've come to take over this honor and archive all
the goings on here. I hope I can do a good job, and allow the summaries to
continue being a useful and transparent fixture.

Also, after catching up with my backlog of summary work, I plan to begin the
first summaries of python-3000 (and, possibly, but not likely, the python-
ideas list), as more and more actual work, rather than debating and theory-talk,
is going on there.

Sincerly,
Your new summary writer,
Calvin Spealman

Summaries
=========

-------------------------
Indexing of Match Objects
-------------------------

Subscripting re match objects directly was proposed and the debate the waged
mostly on how to deal with slicing and m.group(0) to be the entire match. The
consensus seemed to be that returning a match object would break, largely
because m[1:2][0] != m[1], which breaks intuition with slices. Returning a list
as a slice also breaks the intuitions about the type of a slice.

Contributing thread:

- `a feature i'd like to see in python #2: indexing of match objects <http://mail.python.org/pipermail/python-dev/2006-December/070138.html>`__

----------------------------------------
Python and the Linux Standard Base (LSB)
----------------------------------------

Discussions about how to properly document the expected Python environment for
all LSB compliant distributions continued shortly. Focus was on how distros have
a need to split the standard library up, even if the entire thing is eventually
installed, and issues such as Tkinter requiring X leading to standard modules
being ommitted for flexable packages.

Contributing thread:

- `Python and the Linux Standard Base (LSB) <http://mail.python.org/pipermail/python-dev/2006-December/070112.html>`__

-------------------------------------
Number of Windows Installer Downloads
-------------------------------------

Guido was impressed with out download numbers on Windows, but most people just
attributed it to other platforms including and mirroring Python. Even taking
that to consideration, the ratio of Windows to source downloads has shifted in
Windows favor a good bit. The use of Python in introductory courses at MIT was
mentioned as something to push these numbers further in the near future.

Contributing thread:

- `[Python-checkins] MSI being downloaded 10x more than all other files?! <http://mail.python.org/pipermail/python-dev/2006-December/070294.html>`__

--------------------------
Deletion Through Iterators
--------------------------

The request was made to allow direct deletion of items from iterables through
the iterator, but the idea was deemed unscalable to iterables in general and
broken with dictionaries. The solutions to work around the problem were given
and generally agreed to be sufficient (such as copying all the items you want
to keep, instead).

Contributing thread:

- `a feature i'd like to see in python #1: better iteration control <http://mail.python.org/pipermail/python-dev/2006-December/070137.html>`__

-------------------------
LSB: Binary compatibility
-------------------------

The other side of the LSB issue was discussed, related to the CPython ABI, the
.pyc bytecode and the marshall formats, and exactly which versions of Python
may or may not gain a standard ABI, as well as how to carry this forward to
future (already existing and evolving) version of Python. Some mention was made
of the difficulties and conflicts being brought on by the idea of LSB standards
for Python, while the benefits of this were challenged.

Contributing thread:

- `LSB: Binary compatibility <http://mail.python.org/pipermail/python-dev/2006-December/070191.html>`__

----------------------------------------
Adding resume (206) support to urllib(2)
----------------------------------------

Daniel Watkins asked about adapting his HTTP resuming support into urllib, but
suggestions directly moved this to urllib2 and then to httplib. The conversation
quickly drifted into talking about how abstract and minimal the urllib(2) should
be, while the httplib module may grow increasing complex and feature supporting.
The original poster made no final comment on his intentions to follow through
with the patch.

Contributing thread:

- `Adding resume (206) support to urllib(2) <http://mail.python.org/pipermail/python-dev/2006-December/070320.html>`__

-------------------
__str__ and unicode
-------------------

The details of what an object's __str__() method must return were inquired. Must
the string returned by a str or any basestring? It was announced to allow
unicode objects, with no restriction on content. However, the caution that the
return is likely to be encoded into the default encoding was given.

Contributing thread:

- `__str__ and unicode <http://mail.python.org/pipermail/python-dev/2006-December/070237.html>`__

----------------------------------
LSB: Selection of a Python version
----------------------------------

Martin v. Lowis announced that LSB will likely move forward with Python 2.4 as
the first LSB standard Python version. How to handle future bug patches, as well
as the comfort of the distributions for being required to support an outdated
package (2.4 is already "retired") was considered. The consensus settled on a
documented support for 2.4 moving forward with security patches, and likely
even 2.3, as security patches are rare enough to not cause too many cycles to
be spent on them.

Contributing thread:

- `LSB: Selection of a Python version <http://mail.python.org/pipermail/python-dev/2006-December/070189.html>`__

------------------------------
Threading, atexit, and logging
------------------------------

A bug (#1566280) was previously reported, related to the ordering of the atexit
handlers for the logging and threading modules. Participants in the thread had
a general agreement that the threading module using such a user visiable
mechanism for cleanup and lifetime was a bad design in the first place to be
remedied.

Contributing thread:

- `Threading, atexit, and logging <http://mail.python.org/pipermail/python-dev/2006-December/070233.html>`__

-----------------------------------
Creating dicts from dict subclasses
-----------------------------------

The built-in types can now be subclassed, but C code doesn't always realize
this, and relies too heavily on the internals of the base class.  In this case,
PyDict_Merge was assuming too much; replacing the PyDict_Check test with
PyDict_CheckExact fixed the bug, but slowed things down a lot.

Walter Dorwald suggested adding a not-quite-as-fast path for sensible mappings
(including dict subclasses).  Unfortunately, there was a bit of disagreement
over what constituted "sensible".  Should the middle-speed path use iteration
over items (the exact content it needed), over keys (a bit faster in the current
implemententation), or not even exist (to avoid limiting future
implementations)?

As of Jan 8, 2007, SVN has not been updated; there is no middle-speed path, and
the bug is still possible.

-----------------------------------------------------------------------------
OT: World's oldest ritual discovered. Worshipped the python 70, 000 years ago
-----------------------------------------------------------------------------

This was a quick and off-topic post about other instances of python symbolism in
ancient humanity, including a definition of our word "pythonic" to mean
"prophetic", which seems fitting enough.

Contributing thread:

- `OT: World's oldest ritual discovered. Worshipped the python 70, 000 years ago <http://mail.python.org/pipermail/python-dev/2006-December/070123.html>`__

------------------
LSB: pyc stability
------------------

The LSB meetings brought up the issue of standardized bytecode formats, again.
This has always been something discouraged from Python. Keeping the bytecode
format free and the implementation open to ignoring old versions, has always
been helpful for maintanence and development. The common reasoning of protecting
IP was used, although most in-the-know consider this to be a false sense of
security. Reguardless, it might be useful in legal ways, as trade secrets do
require a reasonable attempt at hidding them in order to be recognized as such.

The possible solution of importing encypted zip packages with a custom import
hook was proposed and seems logical.

Contributing thread:

- `LSB: pyc stability <http://mail.python.org/pipermail/python-dev/2006-December/070187.html>`__

-------------------------------
Interpolated Strings (ala perl)
-------------------------------

Perl/PHP style string interpolation was brought up, but is found unreasonable
for various reasons. Cons include the use of format strings in scopes outside
where they are defined, the dangers of eval, and possibly the general resisting
of any idea coming from Perl. This seems a highly unlikely proposal.

Contributing thread:

- `features i'd like [Python 3000?] ... #4: interpolated strings ala perl <http://mail.python.org/pipermail/python-dev/2006-December/070173.html>`__

---------------------------
Polling with Pending Calls?
---------------------------

Issues with the RPM library blocking interupts for long periods of time were
brought up with proposed fixes by patching the rpmlib bindings to
"automagically" poll for any pending calls. An existing patch was suggested but
did not seem to fit the case at hand.

Contributing thread:

- `Polling with Pending Calls? <http://mail.python.org/pipermail/python-dev/2006-December/070181.html>`__

---------------------
Cross-compile Patches
---------------------

Patch 1597850 is being actively worked, and will improve the experience when
compiling python for freeBSD from a linux environment.

Contributing thread:

- `cross-compile patches <http://mail.python.org/pipermail/python-dev/2006-December/070216.html>`__

------------------------------------
Open CPython VM for type information
------------------------------------

Would it make sense to modify the CPython virtual machine (bytecode) so that it
was easier for other programs to produce bytecode?  Answer: No -- those programs
should produce either C (which gets called as a function) or python (which gets
interpreted by the python interpreter -- there are already interpreters that
don't use CPython bytecode.

Subject: ANNOUNCE: Spiff Guard (Generic Access Lists for Python)
Message-ID: <1168211961.5205.4.camel@localhost.localdomain>

Introduction 
------------ 
Spiff Guard is a library for implementing access lists in Python. It 
provides a clean and simple API and was implemented with performance 
and security in mind. It was originally inspired by phpGACL 
(http://phpgacl.sourceforge.net/), but features an API that is 
significantly cleaner and easier to use. 

Spiff Guard is the first library published as part of the Spiff 
platform. The Spiff platform aims to produce a number of generic 
libraries generally needed in enterprise (web) applications. 

Spiff Guard is free software and distributed under the GNU GPLv2.

 * Wordsearch generator sample (80% functional)
 * More controls supported (listbox, webbrowser)
 * More compound controls
 * Controls can now be right-aligned
 * Plenty of bug fixes

TayLayout is a more sophisticated version of the flow layout - you can
add controls to a panel or form and it takes care of positioning them.
Controls are added in a Left to Right order until you specify that a
new line is required.

== Meeting: Wednesday, January 17, 2007 ==

 * Time: 6-8 PM

 * Location: Churchill Navigation, in their spiffy new office at 100
Arapahoe Ave, Suite 10, all the way at the end, in Boulder, Colorado.
There is abundant parking.

 * Tom Churchill and Vinny Fiano will demo Churchill Navigation's
earth-rendering engine (which looks like Google Earth, only apparently
even better and faster ;) ). Vinny (their main Python guy) will explain
how they built the glue logic (and why they decided against SWIG) and
perhaps some of the implications of using Python as a scripting
language in a real-time (60 fps) environment, and the techniques we
employed to keep the graphics pipeline from stalling when making an
expensive call into their engine from Python.

 * Brian Granger from Tech-X will help us think more deeply about
concurrent Python programming, especially as seen in a new version of
IPython.

 * BoulderSprint. We had a great sprint on Jython, focusing on design.
Momentum is really building, Jython might actually get the love that
Charles Oliver Nutter of JRuby proposed. More interestingly, there's a
chance for people in the dynamic language community to work together on
JVM implementations. We will talk about the next sprint to be held on
Saturday, February 3.

We will have food & drink available. Hope to see you there!

Subject: itools 0.15.1 released
Message-ID: <45ABAB57.8060606@itaapy.com>

itools is a Python library, it groups a number of packages into a single
meta-package for easier development and deployment:

  itools.catalog        itools.http             itools.uri
  itools.cms            itools.i18n             itools.vfs
  itools.csv            itools.ical             itools.web
  itools.datatypes      itools.rss              itools.workflow
  itools.gettext        itools.schemas          itools.xhtml
  itools.handlers       itools.stl              itools.xliff
  itools.html           itools.tmx              itools.xml

This release brings some new features to itools.cms, and a lot of aesthetic
and usability improvements:

  - Two new object types have been added, a forum and a wiki;
  - Added a contact form;
  - Added a forgotten password form;
  - Changed the layout of the menus;
  - Updated colors, icons and views here and there.

Other than this the focus of 0.15.1 has been to clean the code. Specially
the support for dates and times, and the programming interface of
configuration handlers, has been improved.


Credits:

 - Herv? Cauwelier contributed the Forum and Wiki objects, and worked to
   improve the user's experience;
 - J. David Ib??ez added the contact and forgotten password forms, and
   worked on the user interface and cleaning the source code;
 - Sylvain Taverne fixed the Dublin Core schema.

Subject: [ANN] Aspen 0.7 -- WSGI + filesystem = sweet webserver
Message-ID: <45AC02A2.2050402@zetaweb.com>

Greetings, program!

I've just released Aspen 0.7. Aspen is a Python webserver, and 
this is the first version to be used in production. As such, I'm 
announcing it generally as well as to the Web-SIG.

This release is about making Aspen easy to configure, and making 
that configuration easy to get to from your WSGI modules. I'm 
pleased with the result, and would love to hear your feedback.

Also, allow me to thank the following for being Aspen's first 
contributors:

   * Giorgi Lekishvili, for initial optimization work
   * Maciek Starzyk, for keeping us honest on Windows
   * Vasilis Dimos, for providing benchmarks
   * alefnula, for feedback on supporting Range requests


Downloads, docs, and links are here:

Subject: ANN: shove 0.1, the next-generation shelve
Message-ID: <1168976504.852657.121130@a75g2000cwd.googlegroups.com>

shove is a object storage frontend inspired by the standard library's
shelve module. It features a dictionary-style API, automatic object
storage (with pickle) with in-storage compression (with zlib), and
multiple storage and caching backends.

The currently supported storage backends are:

    * Amazon S3 Web Service
    * Berkeley Source Database
    * Filesystem-based
    * Firebird
    * FTP
    * DBM
    * Durus
    * Memory
    * Microsoft SQL Server
    * MySQL
    * Oracle
    * PostgreSQL
    * SQLite
    * Subversion
    * Zope Object Database (ZODB)

Currently supported caching backends are:

    * Filesystem-based
    * Firebird
    * memcached
    * Memory (thread-safe or non-thread-sa
    * Microsoft SQL Server
    * MySQL
    * Oracle
    * PostgreSQL
    * SQLite

The simplest use case for shove is:

from shove import Shove

store = Shove()

creating an in-memory store and cache.

To use a different storage or caching backend, a backend-specific URI
or an existing store or cache instance must be passed to the Shove
class using the format:

<STORENAME> = Shove(<STORE>, <CACHE>)

Each backend-specific URI format is documented in its module source
code. The URI format follows the URI format used by SQLAlchemy:

http://www.sqlalchemy.org/docs/dbengine.myt#dbengine_establishing

shove is available for download from its CheeseShop page:

http://cheeseshop.python.org/pypi/shove

or it can be installed by using setuptools:

easy_install shove

shove has been tested and confirmed to work on Python 2.4 and Python
2.5.

shove has an extension, multishove, with the same features but with
added support for storing objects to multiple storage backends
simultaneously. shove itself can only store objects to one backend at a
time.

To use multiple backends with multishove, multiple backend-specific
URIs or store instances must be passed to the MultiShove class
following the format:

from multishove import MultiShove

<STORENAME> = MultiShove(<STORE1>, <STORE2> ..., cache=<CACHE>)

multishove is available for download from its CheeseShop page:

http://cheeseshop.python.org/pypi/multishove

or it can be installed by using setuptools:

easy_install multishove

multishove has been tested and confirmed to work on Python 2.4 and
Python 2.5.

Message-ID: <2ba084-c0j.ln1@home.rogerbinns.com>

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

APSW 3.3.10-r1 is now available.

Home page: http://www.rogerbinns.com/apsw.html

APSW provides an SQLite 3 wrapper that provides the thinnest layer over
SQLite 3 possible. Everything you can do from the C API to SQLite 3, you
can do from Python. Although APSW looks vaguely similar to the DBAPI, it
is not compliant with that API and instead works the way SQLite 3 does.

This release must be used with SQLite 3.3.10 or above

Notable changes since the last release:

* Even more test cases (you can't have too many!)

* Augmented stack traces giving more details when errors or exceptions occur

http://www.rogerbinns.com/apsw.html#augmentedstacktraces

* String/Unicode values work correctly if they have embedded NULL
characters (ie not truncated at the NULL).

* You can load SQLite shared library extensions.

* You can write virtual tables in Python

http://www.sqlite.org/cvstrac/wiki?p=VirtualTables
http://www.rogerbinns.com/apsw.html#VirtualTables

* You must call close() on connections. You can also call close on
cursors, but it usually isn't necessary.

* All strings are returned as unicode

* Uses the sqlite3_prepare_v2 api which means SQLITE_SCHEMA no longer
occurs except when there is a permanent error

* Added a statement cache

Subject: [ANN] argparse 0.5 - Command-line parsing library
Message-ID: <d11dcfba0701161822o8e37c20n20daf17825c85c44@mail.gmail.com>

Announcing argparse 0.5
-----------------------

argparse home:
   http://argparse.python-hosting.com/

argparse single module download:
   http://argparse.python-hosting.com/file/trunk/argparse.py?format=raw

argparse bundled downloads at PyPI:
   http://www.python.org/pypi/argparse/

About this release
==================

This release adds support for required options, better support for
opening files (deprecating the 'outfile' type), better control over
help formatting and better support for negative number arguments.

New in this release
===================

* Required options may now be created by specifying required=True in
calls to add_argument.
  http://argparse.python-hosting.com/wiki/ArgumentParser/add_argument/required

* The 'outfile' type has been deprecated. Use the new FileType factory
which can be used to specify both file mode and buffer size, and knows
how to convert '-' into sys.stdin or sys.stout as appropriate. The
'outfile' type will be removed in a future release.
  http://argparse.python-hosting.com/wiki/FileType

* The ArgumentParser constructor now accepts a ``formatter_class``
keyword argument which can be set to
argparse.RawDescriptionHelpFormatter to keep argparse from
line-wrapping your description.

* The algorithm in parse_args() has been enhanced to understand that
negative numbers are usually positional arguments, not misspelled
optional arguments.

About argparse
==============

The argparse module is an optparse-inspired command line parser that
improves on optparse by:

* handling both optional and positional arguments
* supporting parsers that dispatch to sub-parsers
* producing more informative usage messages
* supporting actions that consume any number of command-line args
* allowing types and actions to be specified with simple callables
instead of hacking class attributes like STORE_ACTIONS or
CHECK_METHODS

as well as including a number of other more minor improvements on the
optparse API. To whet your appetite, here's a simple program that sums
its command-line arguments and writes them to a file::

    parser = argparse.ArgumentParser()
    parser.add_argument('integers', nargs='+', type=int)
    parser.add_argument('--log', default=sys.stdout,
                        type=argparse.FileType('w'))
    args = parser.parse_args()
    args.log.write('%s\n' % sum(args.integers))
    args.log.close()

Subject: ANN: amplee 0.4.0
Message-ID: <45AE3BAC.2020909@defuze.org>

Hi all,

I finally released a new version of amplee. I've moved from 0.3.x to
0.4.x as there are a couple of modification to the API that were worse
the bump. I think this version is much more stable and bug free. Mind
you it's a long way before I can claim is entirely unit tested. But it
gets there.

The main modifications since 0.3.6 are:

 * Added a loader feature. I realized that setting up the store was a
recurrent task and I wondered how to help in this task. I came up with
the loader feature. Basically you describe your APP store within a
config file (pure INI) and calls the loader method. This will construct
entirely your store and returns it to you. This is quite handy and makes
the creation of a store much easier.

 * Handler API introduced. Amplee does the best it can to provide you
with an API an tools to handle the dirty work of APP and let you enhance
it by a callback system. In previous version those callbacks were
attached to the collection which forced to some not very friendly hacks.
Now it's a matter of creating a class that implements a set of methods
which will then be called by amplee at the right moment. This class is
what I call a handler and associated with a media-type that the
collection accepts.

 * The loading and reloading of members is more flexible. In the past
you could solely reload all members of a store or none. Now you have
more granularity upon what should be loaded into a collection's cache.

 * Many notable bugs have been fixed in the handling of Atom within the
members and they should be much more reliable now.

 * You can now find a small blog example that shows you how to use amplee.

If you think of upgrading you should note that because of the
modification on the callback API you may have some work to do. But this
should not be too difficult.


== Download ==

 * easy_install -U amplee
 * Tarballs http://www.defuze.org/oss/amplee/
 * svn co https://svn.defuze.org/oss/amplee/

Hi all,

I have just released version 0.0.18 of Shed Skin, an optimizing
Python-to-C++ compiler. It allows for translation of pure
(unmodified), implicitly statically typed Python programs into
optimized C++, and hence, highly optimized machine language. Many
non-trivial benchmarks (ray tracer, chess player, othello player, sat
solver, 3 sudoku solvers..) run typically 2-40 times faster than when
using Psyco, 12 times on average, and 2-220 times than when using
CPython, 45 times on average. It is not yet possible to use arbitrary
library modules (many common imports are supported though), or to
automatically create extension modules, but this will be the focus of
development over the coming time, along with support for iterators.

Besides many bug fixes and optimizations, this release should work
fine on OSX and 64-bit systems.

More information about Shed Skin can be found at the homepage:
http://mark.dufour.googlepages.com.

To show how far Shed Skin is at the moment, I added a collection of 25
programs (at a total of more than 6,000 lines!) that compile and run
fine to the homepage. Most (implicitly statically typed) programs
still need to be modified a bit to compile, and much larger programs
than these will probably not work yet..


Thanks,
Mark Dufour.

Subject: PythonTidy 1.10
Message-ID: <20070118145410.GF1352@loki>

PythonTidy cleans up, regularizes, and reformats the text of Python
scripts.

It is released under the GNU General Public License.  

Python scripts are usually so good looking that no beautification is
required.  However, from time to time, it may be necessary to alter
the style to conform to changing standards.  This script converts
programs in a consistent way.  It abstracts the pretty presentation of
the symbolic code from the humdrum process of writing it and getting
it to work.

This is an upgrade.  There was a big problem with earlier versions:
Canonical values were substituted for strings and numbers.  For
example, decimal integers were substituted for hexadecimal, and
escaped strings for raw strings.  Authors of Python scripts usually
use peculiar notations for peculiar purposes, and doing away with the
peculiarity negatively impacts the readability of the code.

This version preserves the original constants (parsed by *tokenize*)
in a literal pool indexed by the value they evaluate to.  The
canonical values (output by *compiler*) are then translated back (when
possible) to the original constants by looking them up in the literal
pool.

Subject: FlightFeather Social Networking Platform 0.2.8 (First Beta)
Message-ID: <20070118213756.GA7704@localhost>

FlightFeather's goal is "social networking for everyone".  This means
that *anyone* should have a chance to run a *popular* social
networking site -- on minimal hardware, and without wasting bandwidth.

Release 0.2.8 is the first beta version of FlightFeather.  This
release also adds a facility for recursively finding and running all
doctests.  In addition, the package includes web functionality tests,
written using the Selenium test tool.

You can download release 0.2.8 (free/open source under the GPL) from
the "BoSStats" site, which runs on FlightFeather.

     http://www.bosstats.com/flightfeather.html

You are always welcome to participate in the discussion on the
"BoSStats" site; the topic covered (what makes a good boss, office
politics, etc.) is valuable in and of itself.  Please, however,
refrain from posting test comments, as the site is live.


A Brief Overview of FlightFeather and BoSStats
----------------------------------------------
FlightFeather is in its early stages, but it is functional.  You can
see the system in action on the BoSStats site.  BoSStats is
dedicated to improving the world of work: you can discuss what makes a
good boss, or share your experiences of office politics. You can also
comment and vote on the posts made by others.  The application does
not set cookies, and no registration is required for anything except
voting.


     http://www.bosstats.com/


BoSStats is a good testbed for FlightFeather, and has value of its
own, since meaningful advice about work-related problems is very hard
to find.  A "Wisdom of Crowds" solution -- particularly with strong
privacy protection (see below) -- is a necessary addition to this
field.

FlightFeather's most important feature is that all write requests
generate (or modify) HTML files.  In consequence, a pure read (the
most common operation) merely serves static pages.

The major design focus for FlightFeather are responsiveness and
performance; the system should eventually support very high traffic
volumes.  In addition, FlightFeather allows for a great deal of user
privacy -- a critical, rapidly emerging problem in the social
networking realm.

Subject: ANN: Phebe 0.1.1
Message-ID: <pan.2007.01.19.21.52.34.231973@thomas-lotze.de>

Phebe 0.1.1 has been released and uploaded to the Python package index as
a source and binary distribution and as an egg.

The most important changes since version 0.1 are:

User-visible:
  - phoneusage: new -s/--sms option to list number of short messages per
    contact

  - dumpmessages: filter messages by index and conversations by name

  - deletemessages: print number of messages when asking to show conversations

  - all scripts: -p/--prefix option to provide default national prefix
                 (also added a "Local" section with key "prefix" to rc files)

Bug fixes:
  - contact names are now resolved regardless of national vs. international
    phone numbers thanks to newly-introduced prefix option

Organization:
  - using setuptools now to distribute Phebe as a Python egg


>From README.txt:

========================================================================

Phebe comprises a Python package and a number of executable scripts to
operate a mobile phone connected to your computer.


The implementation follows the Sony-Ericsson developer guidelines for using AT
commands as of December 7, 2006, see
<http://developer.sonyericsson.com/getDocument.do?docId=65054>. It has been
tested only on a SE K750i, using Debian and Gentoo Linux distributions with a
2.6 kernel so far.

The current status of Phebe is "works for me", i.e. it provides the
functionality the author immediately needs: get usage stats of the phone,
back-up the phonebook, dump and delete short messages. See ROADMAP.txt and
TODO.txt for prospective further developments.

While neither talking through the AT command interface nor the higher-level
data structures implemented by Phebe are operating system specific,
communication with the device is. Phebe currently does this by using a Python
module only available on Unix. The author is not going to port Phebe to
non-Unix systems any time soon, so if you want it to support your OS, you have
to supply an appropriate patch.


Phebe is written by Thomas Lotze. Please contact the author at
<thomas at thomas-lotze.de> to provide feedback or suggestions on or
contributions to Phebe.

=========================================================================

Phebe requires Python 2.5.

The Phebe code base is maintained in a subversion repository at
<https://svn.thomas-lotze.de/repos/public/Phebe>.

There is a ViewCVS view on the repository available at
<http://svn.thomas-lotze.de/public/Phebe>.

There is a web page summarizing the project at

Subject: [ANN] Movable Python 2.0.0 Final Available
Message-ID: <1169255171.932282.195700@m58g2000cwm.googlegroups.com>

Movable Python 2.0.0 Final
<http://www.voidspace.org.uk/python/movpy/>`_ is now available.

The new binaries are available for download from the groups page :

* `Movable Python Groups Page
<http://voidspace.tradebit.com/groups.php>`_

Binaries are uploaded for Python 2.2.3, 2.3.5, 2.4.4, 2.5 and the
`MegaPack <http://www.voidspace.org.uk/python/movpy/megapack.html>`_.

There is also a fresh version of the free demo, based on Python 2.3.5:

* `Movable Python Trial Version
<http://voidspace.tradebit.com/files.php/7007>`_


What is Movable Python
==================

**Movable Python** is a distribution of Python, for Windows, that can
run without being installed. It means you can carry a full development
environment round on a USB stick.

It is also useful for testing programs with a 'clean Python install',
and testing programs with multiple versions of Python.

The GUI program launcher makes it a useful programmers tool, including
features like :

* Log the output of all Python scripts run
* Enable Psyco for all scripts
* Quick Launch buttons for commonly used programs
* Configure multiple interpreters for use from a single interface

It comes with the Pythonwin IDE and works fine with other IDEs like
`SPE <http://developer.berlios.de/projects/python/>`_.

Plus many other features and bundled libraries.


What's New ?
==========


Updated to wxPython 2.8.0, PIL 1.1.6, psyco 1.5.2, ctypes 1.0.1 and
pyEnchant 1.3.0.

Fixed bug so that the documentation will launch from the menu.

Subject: [ANN] wxPython 2.8.1.1
Message-ID: <45B3F7B7.4030006@alldunn.com>



Announcing
----------

The 2.8.1.1 release of wxPython is now available for download at
http://wxpython.org/download.php.  This release adds a few minor
enhancements and a number of bug fixes designed to further stabalize
the 2.8.x release series.

Source code is available, as well as binaries for both Python 2.4 and
2.5, for Windows and Mac, as well some pacakges for various Linux
distributions.  A summary of changes is listed below and also at
http://wxpython.org/recentchanges.php.


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 Python extension module that wraps 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 Microsoft Windows, most Linux
or other Unix-like systems using GTK2, and Mac OS X 10.3+, in most
cases the native widgets are used on each platform to provide a 100%
native look and feel for the application.


Changes in 2.8.1.1
------------------

wxMSW: Fix lack of spin control update event when control lost focus

Added a typeId property to the PyEventBinder class that holds the
eventType ID used for that event.  So when you need the eventType
(such as when sending your own instance of standard events) you can
use, for example, wx.EVT_BUTTON.typeId instead of
wx.wxEVT_COMMAND_BUTTON_CLICKED.   Note that there are a few composite
events, such as EVT_MOUSE and EVT_SCROLL, that will actually bind
multiple event types at once, and in these cases the typeId property
may not give you what you want.  You should use te component events in
these cases.

PyCrust now has an option for showing/hiding the notebook.

wxMSW:  Corrected drawing of bitmaps for disabled menu items.

Enhanced the wx.lib.mixins.inspect module.  In addition to showing a
PyCrust window it is now a widget browser, which provides a tree
loaded up with all the widgets in the app, optionally with the sizers
too, and also a panel displaying the properties of the selected
window.  Run the demo and type Ctrl-Alt-I keystroke (or Cmd-Alt-I on
the Mac) to see how it works.  You can add this to your own apps with
just a few lines of code.

Added wx.SearchCtrl.[Get|Set]DescriptiveText

wxMac: Added support for the wx.FRAME_FLOAT_ON_PARENT style.

wxMac: the popups used for call tips and autocomplete lists in
StyledTextCtrl (such as in PyShell) are now top-level float-on-parent
windows so they are no longer clipped by the bounds of the stc window.

Added EVT_TASKBAR_CLICK and use it to show taskbar icon menu on right
button release, not press, under MSW (bug 1623761)

Added wx.TreeCtrl.CollapseAll[Children]() and IsEmpty() methods

Fix wx.MDIChidFrame.GetPosition() (patch 1626610)

Fix attribute memory leak in wx.grid.Grid::ShowCellEditControl() (patch
1629949)

wxGTK: Fix for controls on a toolbar being the full height of the
toolbar instead of their natural height.

wx.lib.customtreectrl patches from Andrea Gavana.

wxMac: Applied patch #1622389, fixing two memory leaks in
GetPartialTextExtents.

More fixes for the native wx.ListCtrl on Mac.

Added wx.aui.AuiNotebook.GetAuiManager().

Added wx.aui.AuiMDIParentFrame and wx.aui.AuiMDIChildFrame, which
essentially implement the MDI interface using a normal wx.Frame and a
wx.aui.AuiNotebook.

Subject: PyPy Trillke Sprints Feb/March 2007
Message-ID: <20070122155954.GS16915@solar.trillke>

=========================================================================
PyPy Trillke "EU and beyond!" sprints (25-28th Feb, 1-5th March 2006)
=========================================================================
..    image:: http://www.trillke.net/images/HausPanorama0304_113kb.jpg

Some two years and some thousands of commits later, the EU
project period of the PyPy (http://codespeak.net/pypy) project
is about to close ...  and a new period to begin: we are going
for a sprint of three days of focusing on EU reports and
administrative issues, and another three day sprint of happy 
hacking on the numerous interesting open ends of PyPy, 
the source code.    

We also intend to discuss and state our view on the time after
the EU period (March 2007 is the last EU funded month),
because clearly the project will not stop after our successful
(knock knock!) completion of the EU project.  It's already
clear that some of us seriously plan for a relaxation time, 
i.e. one without having many obligations.  But that should
not keep us from thinking and envisioning the development 
from April on.  

So to the Sprint: we have two parts of the sprint, first the EU 
and second the public all-invited part:: 

    26th Feb - 28th Feb     EU reports and adminstrative sprint
    1st March               break day / arrival for coding sprint
    2nd March - 4th March   public coding "beyond EU" sprint days

All days are meant as full days, so please arrive 25th Feb / 1st March 
and leave 5th March if you can (this help us with pairing, introductions 
and logistical planning). 

---------------------------------------------
Possible Topics for the coding sprint 
---------------------------------------------

* working on .NET, Java and other backends 

* working on the Javascript, Prolog or a new frontend

* Tuning the JIT, refining approaches `[1]`_

* Fixing PyPy-1.0 problems / improving it (PyPy-1.0 is
  scheduled for Mid February, btw)

* improving the py lib/py.test, build environments, preparing 
  for server administration efforts from April on 

* Work on/with prototypes that use the new features that PyPy enables:
  distribution `[2]`_ (based on transparent proxying `[3]`_),
  security `[4]`_, persistence `[5]`_, etc. `[6]`_.

* discussion about the time after March, and how to
  organize/co-ordinate ourselves 

* all topics that are of interest otherwise (including
  maybe working on some particular EU related topics still!)

-----------------------
Location 
-----------------------

The sprint takes place at the 

    Trillke Gut 
    Steinbergstr. 42
    Hildesheim, Germany 
    http://www.trillke.net

If you come to Hildesheim main station, take the 

    Bus Number 3 (Hildesheimer Wald)

and get out at "Waldquelle".  Walking back a 100 meters gets you
to a small street on the right leading to a big white building, the
Trillke Gut. 

We'll have at least one larger room for sprinting,
and a kitchen for our use.  

-----------------------
Accomodation 
-----------------------

We can probably arrange for some cheap or no-cost private 
accomodation, in private rooms located up in the house 
(and being part of "living groups" of 5-10 people).  

There also is a nice Guest house that has been used
during recent events: 

    http://www.gaestehaus-klocke.de/

and a four-star hotel 500 meters away from the Trillke:

Subject: FlightFeather Social Networking Platform 0.3.0
Message-ID: <20070123233955.GA31734@localhost>

FlightFeather's goal is "social networking for everyone".  This means
that *anyone* should have a chance to run a *popular* social
networking site -- on minimal hardware, and without wasting bandwidth.

Release 0.3.0 is the current development release. It introduces a
feature that allows easy submission of FlightFeather-hosted content to
Digg. Generic utility functions perform most of the work, so it should
be relatively straightforward to extend support to other social
networking sites in the future.

The current beta release of FlightFeather is 0.2.8.  You can download
these releases (free/open source under the GPL) from the "BoSStats"
site, which runs on FlightFeather.
                                                 
     http://www.bosstats.com/flightfeather.html  

You are always welcome to participate in the discussion on the
"BoSStats" site; the topic covered (what makes a good boss, office
politics, etc.) is valuable in and of itself.  Please, however,
refrain from posting test comments, as the site is live.


A Brief Overview of FlightFeather and BoSStats
----------------------------------------------
FlightFeather is in its early stages, but it is functional.  You can
see the system in action on the BoSStats site.  BoSStats is
dedicated to improving the world of work: you can discuss what makes a
good boss, or share your experiences of office politics. You can also
comment and vote on the posts made by others.  The application does
not set cookies, and no registration is required for anything except
voting.
       
       
     http://www.bosstats.com/


BoSStats is a good testbed for FlightFeather, and has value of its
own, since meaningful advice about work-related problems is very hard
to find.  A "Wisdom of Crowds" solution -- particularly with strong
privacy protection (see below) -- is a necessary addition to this
field.

FlightFeather's most important feature is that all write requests
generate (or modify) HTML files.  In consequence, a pure read (the
most common operation) merely serves static pages.

The major design focus for FlightFeather are responsiveness and
performance; the system should eventually support very high traffic
volumes.  In addition, FlightFeather allows for a great deal of user
privacy -- a critical, rapidly emerging problem in the social
networking realm.

Subject: Pydev 1.2.6 Released
Message-ID: <cfb578b20701240306o7ccb1edau3a730dbd7c852752@mail.gmail.com>

Hi All,

Pydev and Pydev Extensions 1.2.6 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:
-----------------------------------------------------------------

*  Added refactoring support for rename (still BETA, so, don't forget to
review your changes before applying them)
      - Keybinding: Alt+Shift+R
      - Supports preview
      - Integrated in the editor (but not in the package explorer, so, it
can rename a module, but only through an import to that module)
      - Supports undo/redo in the workspace
      - Rename class
      - Rename method
      - Rename attribute
      - Rename imports
      - Rename local variable
* Menu changes:
      - Now the debug/navigate actions are all under a 'Pydev' menu
      - The pydev navigate action is now only initially shown in the
pydev/debug perspective
      - The pydev remote debugging actions are now only initially shown in
the debug perspective
* Fix: code analysis problem when working with nested list-comprehensions
* Fix: go to definition sometimes failed to find module definitions


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

* Pydev package explorer (Still BETA, so, use it with care -- the navigator
is still the preferred way of browsing your project)
      - Filters for .pyc and .pyo files created
      - Working set integration added (just available for Eclipse 3.2.1)
      - Some minor bugs fixed
* Patch by Olof Wolgast: The 'create docstrings' assistant has more options
(windows > preferences > pydev > code formatter > docstrings)
      - Option to choose between single and double quotes
      - Option to create '@type' too and not only '@param'
      - Option to skip creation of the @type tag for parameters starting
with some prefix (if 'Custom' is chosen)
* Block comments now have more options (windows > preferences > pydev > code
formatter > block comments)
      - Option to align single-line block comment to the left or right
      - Option to put class name above class if applied on a class
definition
* Fix: Multi-line Templates indent correctly
* Fix: When a file from a project that was deleted was still opened inside
pydev, Eclipse would not start-up correctly
* Fix: When a different interpreter is chosen in the run dialog, the
pythonpath is correctly gotten
* Fix: when Pydev was started, it would re-save the .pydevproject file even
if no change was done
* Fix: When tab width was set to 0 it could halt the editor (now if 0 is
set, 4 is assumed)
* Grammar Patch by Ueli Kistler, Dennis Hunziker




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,

Message-ID: <435DF58A933BA74397B42CDEB8145A8608C50B13@ex9.hostedexchange.local>

The Dejavu Object-Relational Mapper (version 1.5.0RC1) is now available 
and in the public domain. Get it at http://projects.amor.org/dejavu,
or from PyPI: http://www.python.org/pypi/Dejavu/1.5.0RC1.

Dejavu is an Object-Relational Mapper for Python applications. It is
designed to provide the "Model" third of an MVC application. Dejavu
avoids making decisions in the framework which are better left to
developers, and avoids forcing developers to make decisions which are
better left to deployers. In particular, deployers are allowed to mix
and match storage mechanisms, including how and when to cache objects in
memory, making it easier for deployers to tune applications to their
particular environment.

Dejavu provides:

MODELING LAYER
1. A base Unit class for persisting objects to storage.
2. A base UnitProperty class for persistent object attributes.
3. ID Sequencers.
4. Associations between Unit classes.
5. Unit Engines, Rules, and Collections.
6. Aggregation and analysis tools.

APPLICATION LAYER
1. Expressions: pure Python lambda querying. This is perhaps the most
   appealing feature of Dejavu.
2. Sandboxes, which serve as Identity Maps, transaction boundaries,
   and per-connection caches.
3. An Arena class for application-level data.

STORAGE LAYER
1. A base StorageManager class and specification. Unlike many ORMs,
   Dejavu does not require you to have complete control of the back end.
2. Specific StorageManagers for:
   a. Microsoft SQL Server/MSDE
   b. Microsoft Access (Jet)
   c. PostgreSQL
   d. MySQL
   e. SQLite
   f. Shelve
   g. Firebird
   h. RAM
   i. Filesystem

What's New in 1.5:
http://projects.amor.org/dejavu/wiki/WhatsNewIn15

 * Native ID sequencing.
 * Distributed transactions and tested isolation levels.
 * Complete database introspection and auto discovery.

 * New Firebird support.
 * New RAM Storage Manager.
 * New psycopg2 support.
 * New support for using the sqlite3 module built into Python 2.5.
 * Support for typed and typeless SQLite.
 * Support for SQLite :memory: databases.

 * Complete numeric precision and scale support.
 * Native date function support.
 * Complete M x N type-adaptation.
 * Bulletproof encoding support.
 * New 'range' function which returns the closed interval [min(attr),
..., max(attr)].
 * New 'sum' function which returns the sum of all non-None values for
the given cls.attr.
 * Multiple and custom Associations.
 * Improved performance (especially ADO).
 * New JSON encoder/decoder.
 * Short config names for Storage Managers.
 * ADO: New support for the CURRENCY datatype.
 * ADO: Improved string comparisons using Convert and StrComp.

Subject: ANN: tl.googlepagerank
Message-ID: <pan.2007.01.24.23.54.07.89996@thomas-lotze.de>

I've released tl.googlepagerank 0.1, a package and a script for querying
the Google page rank of individual URLs. This is done the same way the
Google toolbar accesses page ranks.

The package is available from the Python package index as a source
distribution and as eggs for both Python 2.4 and 2.5:

http://cheeseshop.python.org/pypi/tl.googlepagerank

On a side note, this project is the first to live in the tl package
namespace. Should a tl package or package namespace be in official use
already, I'm not aware of it and would appreciate learning about it.

>From tl.googlepagerank's README.txt:

=====================================================

Run the script with any number of command line parameters. It takes each
parameter to be a URL to query Google for. Each query may take some time,
typically a couple of seconds. These are two sample runs, the dollar character
representing your system's command prompt:

$ googlepagerank http://www.google.com/ http://www.thomas-lotze.de/
10 http://www.google.com/
 4 http://www.thomas-lotze.de/

$ googlepagerank http://www.example.com/foobar http://foobar
   http://www.example.com/foobar
RE http://foobar

Google page ranks range from 1 (unimportant) to 10 (important).
An empty page rank means Google has not yet assigned a rank to the URL.
"IO" instead of a page rank means there was an error contacting Google.
"RE" means Google's response could not be understood.

=====================================================

The code is maintained in a subversion repository at
<https://svn.thomas-lotze.de/repos/public/googlepagerank>.

There is a ViewCVS view on the repository available at
<http://svn.thomas-lotze.de/public/googlepagerank>.

The project is also described briefly at
<http://www.thomas-lotze.de/en/software/>.

Subject: FlightFeather Social Networking Platform 0.3.1
Message-ID: <20070125215519.GA15171@localhost>

FlightFeather's goal is "social networking for everyone".  This means
that *anyone* should have a chance to run a *popular* social
networking site -- on minimal hardware, and without wasting bandwidth.

Release 0.3.1 is the current development release. It adds a safe
shutdown feature to the FlightFeather server, eliminating the need for
the two-step shutdown procedure described in "QuickStart.txt". The new
feature also allows you to stop the server remotely, from a list of
trusted IP addresses (set to just 127.0.0.1 by default).

The current beta release of FlightFeather is 0.2.8.  You can download
these releases (free/open source under the GPL) from the "BoSStats"
site, which runs on FlightFeather.

     http://www.bosstats.com/flightfeather.html

You are always welcome to participate in the discussion on the
"BoSStats" site; the topic covered (what makes a good boss, office
politics, etc.) is valuable in and of itself.  Please, however,
refrain from posting test comments, as the site is live.


A Brief Overview of FlightFeather and BoSStats
----------------------------------------------
FlightFeather is in its early stages, but it is functional.  You can
see the system in action on the BoSStats site.  BoSStats is
dedicated to improving the world of work: you can discuss what makes a
good boss, or share your experiences of office politics. You can also
comment and vote on the posts made by others.  The application does
not set cookies, and no registration is required for anything except
voting.


     http://www.bosstats.com/


BoSStats is a good testbed for FlightFeather, and has value of its
own, since meaningful advice about work-related problems is very hard
to find.  A "Wisdom of Crowds" solution -- particularly with strong
privacy protection (see below) -- is a necessary addition to this
field.

FlightFeather's most important feature is that all write requests
generate (or modify) HTML files.  In consequence, a pure read (the
most common operation) merely serves static pages.

The major design focus for FlightFeather are responsiveness and
performance; the system should eventually support very high traffic
volumes.  In addition, FlightFeather allows for a great deal of user
privacy -- a critical, rapidly emerging problem in the social
networking realm.

Message-ID: <67dd1f930701271533p688fd0b7i1c0277a8fcc7654@mail.gmail.com>

Hi all,

Release 0.61.6 of Task Coach is a bug-fix release that hopefully fixes
the following bugs:

* Crash on trying to use down-arrow to move to sub-task.
* When deleting a task that has subtasks that belong to categories, the task
file gets 'corrupted', giving errors when loading it.

In addition, this release of Task Coach should also be able to read and
automatically repair task files that were corrupted by the previous release.


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
https://sourceforge.net/projects/taskcoach/

In addition to the source distribution, packaged distributions are
available for Windows XP, Mac OSX, 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

               Extended submission deadline: 15 February 2007

============================================================================

Dynamically typed programming languages were once seen as slow, unreliable,
and suitable only for small throw-away tasks. However, their ability to aid
rapid systems development and to facilitate the pervasive, mobile, and
frequently updated systems that are increasingly in demand in the modern
world has led to their stock rising considerably.

While developers are ever keen to find out more about the details of dynamic
programming languages, managers are interested in finding out how they can
complement existing approved languages without diluting their organizations'
technical focus.

We thus solicit contributions in several areas related to dynamic
programming languages. Topics of interest include:

  * Dynamic programming languages "in use".
  * Organizations' experiences in integrating dynamic programming languages
    into their existing language menagerie.
  * Experiences of and techniques for using dynamic programming languages
    effectively (including efficiency and scalability concerns).
  * How dynamic programming languages have evolved and how they might
    develop in the future.
  * New techniques in challenging areas such as metaprogramming, reflection,
    dynamic reconfigurability, and mobility.

For detailed author guidelines, please visit:

  http://www.computer.org/software/author.htm

Manuscripts must not exceed 5,400 words including figures and tables, which
count for 200 words each. Submissions in excess of these limits may be
rejected without refereeing. The articles we deem within the theme's scope
will be peer-reviewed and are subject to editing for magazine style,
clarity, organization, and space.

Hello!

I'm pleased to announce the 0.7.3 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, and
Firebird.  It also has newly added support for Sybase, MSSQL and MaxDB (also
known as SAPDB).

Subject: ANN: Release of SimPy 1.8
Message-ID: <200701311537.l0VFb6ci003173@smtp-vbr7.xs4all.nl>

With great pleasure we announce the availability of SimPy version
1.8 This is a major release, with significant changes to API and
documentation and with a number of bug fixes.

What is SimPy?
==============
SimPy (= Simulation in Python) is an object-oriented, process-based 
discrete-event simulation language completely implemented in Python. It is 
released under the GNU Lesser GPL (LGPL). SimPy provides the modeler 
with components of a simulation model including processes, for active 
components like customers, messages, and vehicles, and resources, for 
passive components that form limited capacity congestion points like 
servers, checkout counters, and tunnels. It also provides monitor 
variables to aid in gathering statistics. Random variates are provided 
by the standard Python random module.

Many users claim that SimPy is one of the cleanest, easiest to use 
discrete event simulation packages! SimPy is in use at many universities,
research institutes and in industry.

SimPy comes with data collection capabilities, GUI and plotting packages. 
It can be easily interfaced to other packages, such as plotting, statistics,
or database systems.

=============================
Release notes for SimPy 1.8
=============================

This version is the result of many months of intense collaboration in
the SimPy community. It includes design ideas and improvements proposed by 
Steve Rogers, Matt Kuperholz and Igor Cananea. It also includes code in 
SimulationRT contributed by Robert C. Ramsdell III which allows setting 
of the simulation to real time ratio during a simulation run. Many thanks
to all contributors! Our apologies if we have forgotten to mention a
contributor!

For the first time, we had an editor/co-author (Bob Helmbold)
working with us on rewriting Manual and Cheatsheet. You will like the
resulting documents!

Important Note:
===============

SimPy 1.8 and future releases will not run under the (obsolete) Python 2.2
version.

Additions
=========

- New compound yield statements support time-out or event-based
  reneging in 'get' and 'put' operations on Store and Level instances.

- 'yield get' on a Store instance can now have a filter function which
  selects which and how many items (e.g.  "3 parcels weighing less than
  3 pounds") should be retrieved.

- All Monitor and Tally instances are automatically registered in
  lists 'allMonitors' or 'allTallies', respectively.

- The new function 'startCollection' allows activation of Monitors and
  Tallies at a specified time (e.g. after a warm up period).

- A 'printHistogram' method was added to Tally and Monitor which
  generates a nicely formatted table-form histogram.

- In SimPy.SimulationRT: A function to allow changing the ratio of
  wall clock to simulation time has been added. It facilitates slowing
  down or speeding up model execution, e.g. for interactive models or
  games.

Changes to code and documentation
=================================

- The Manual has been thoroughly edited, restructured and rewritten
  with a view to greater clarity and readability.  It is provided in
  both HTML and PDF format.

- The Cheatsheet has been rewritten in a tabular format and reduced to
  just a few pages. The goal was to turn it into a concise desktop
  reference of SimPy commands. The Cheatsheet is provided in both XLS
  (MS Excel spreadsheet) and PDF format.

- The obsolete Interfacing document has been replaced by a brief
  introduction to using the matplotlib library for publication-quality
  plotting of SimPy-produced data.

- The version of SimPy.Simulation(RT/Trace/Step) is now accessible by
  the variable 'version'.

- The '__str__' method of Histogram was changed to return a table
  format (like that produced by the new 'printHistogram' method of
  Monitor and Tally).

Repairs
=======

- Repaired a bug in 'yield waituntil' runtime code.

- Introduced check for '<capacity' parameter of a Level or a Store
  being a number > 0.

- Added code so that 'self.eventsFired' gets set correctly after an
  event fires in a compound yield get/put with a waitevent clause
  (reneging case).

- Repaired a bug in prettyprinting of Store objects (the buffer
  content, i.e. '._theBuffer' was not shown) by changing '._theBuffer'
  to '.theBuffer'.

Enjoy!

Best wishes for happy, productive SimPying in 2007!

Subject: PyCon: last day for hotel registrations!
Message-ID: <20070131174026.GA14535@localhost.localdomain>

Today, January 31st, is the last day to make hotel reservations and
obtain the conference rate.  After today, you'll have to pay the
hotel's regular rate, and there's nothing we can do to reduce your
costs.

Go to http://us.pycon.org/Addison/Hotels for hotel information and a
registration link.

Subject: FlightFeather Social Networking Platform 0.3.2
Message-ID: <20070131183250.GA7939@localhost>


FlightFeather's goal is "social networking for everyone".  This means
that *anyone* should have a chance to run a *popular* social
networking site -- on minimal hardware, and without wasting bandwidth.

Release 0.3.2 is the current development release. It updates the
submission feature (which currently supports Digg) introduced in
version 0.3.0. The old behavior was to submit article body text only
up to the first URL in the story. The new approach submits the maximum
allowed text, including any URLs encountered along the way. In the
future, there may be an option to enable the old behavior, as well as
other, alternative ways to process submissions.


The current beta release of FlightFeather is 0.2.8.  You can download
these releases (free/open source under the GPL) from the "BoSStats"
site, which runs on FlightFeather.
                                  
     http://www.bosstats.com/flightfeather.html

You are always welcome to participate in the discussion on the
"BoSStats" site; the topic covered (what makes a good boss, office
politics, etc.) is valuable in and of itself.  Please, however,
refrain from posting test comments, as the site is live.


A Brief Overview of FlightFeather and BoSStats
----------------------------------------------
FlightFeather is in its early stages, but it is functional.  You can
see the system in action on the BoSStats site.  BoSStats is
dedicated to improving the world of work: you can discuss what makes a
good boss, or share your experiences of office politics. You can also
comment and vote on the posts made by others.  The application does
not set cookies, and no registration is required for anything except
voting.
       
       
     http://www.bosstats.com/


BoSStats is a good testbed for FlightFeather, and has value of its
own, since meaningful advice about work-related problems is very hard
to find.  A "Wisdom of Crowds" solution -- particularly with strong
privacy protection (see below) -- is a necessary addition to this
field.

FlightFeather's most important feature is that all write requests
generate (or modify) HTML files.  In consequence, a pure read (the
most common operation) merely serves static pages.

The major design focus for FlightFeather are responsiveness and
performance; the system should eventually support very high traffic
volumes.  In addition, FlightFeather allows for a great deal of user
privacy -- a critical, rapidly emerging problem in the social
networking realm.

Subject: Creating Web 2.0 sites using Python2.5, without a database.
Message-ID: <20070131222337.GA19075@localhost>

LinuxWorld has published my article about the Relative Static approach
to web application design ("BoSStats, FlightFeather and the Relative
Static Web").  

    http://www.linuxworld.com/news/2007/012907-flightfeather.html

This method tries to capture as much system state as possible in
static HTML files, which the webserver can use directly.  While the
resulting site is dynamic, it is static from the webserver's point of
view. I use this approach in my FlightFeather and Flightdeck-UI Online
Free/Open Source projects.

The article describes why Python (specifically version 2.5) is such a
good choice for Relative Static web applications.  The discussion
focuses on the newly introduced "with" statement and the context
manager type (see link to page 5, below).
