lockfile 0.4

I've just released lockfile 0.4.  I separated the test code from the
lockfile module so the module itself should work on Python 2.4.

What is lockfile?  

The lockfile module exports a FileLock class which provides a simple API for
locking files.  Unlike the Windows msvcrt.locking function, the Unix
fcntl.flock, fcntl.lockf and the deprecated posixfile module, the API is
identical across both Unix (including Linux and Mac) and Windows platforms.
The lock mechanism relies on the atomic nature of the link (on Unix) and
mkdir (On Windows) system calls.

HDF5 for Python 1.0

=====================================
Announcing HDF5 for Python (h5py) 1.0
=====================================

What is h5py?
-------------

HDF5 for Python (h5py) is a general-purpose Python interface to the
Hierarchical Data Format library, version 5.  HDF5 is a versatile,
mature scientific software library designed for the fast, flexible
storage of enormous amounts of data.

>From a Python programmer's perspective, HDF5 provides a robust way to
store data, organized by name in a tree-like fashion.  You can create
datasets (arrays on disk) hundreds of gigabytes in size, and perform
random-access I/O on desired sections.  Datasets are organized in a
filesystem-like hierarchy using containers called "groups", and 
accesed using the tradional POSIX /path/to/resource syntax.

This is the fourth major release of h5py, and represents the end
of the "unstable" (0.X.X) design phase.

Why should I use it?
--------------------

H5py provides a simple, robust read/write interface to HDF5 data
from Python.  Existing Python and NumPy concepts are used for the
interface; for example, datasets on disk are represented by a proxy
class that supports slicing, and has dtype and shape attributes.
HDF5 groups are are presented using a dictionary metaphor, indexed

ANN: eGenix mxODBC Connect - Python Database Interface 1.0.0

________________________________________________________________________

ANNOUNCING
                    eGenix.com mxODBC Connect

                    Python Database Interface

                         Version 1.0.0

  Our new client-server product for connecting Python applications
         to relational databases - from all major platforms

This announcement is also available on our web-site for online reading:
http://www.egenix.com/company/news/eGenix-mxODBC-Connect-1.0.0-GA.html

________________________________________________________________________

INTRODUCTION

The mxODBC Connect Database Interface for Python allows users to
easily connect Python applications to all major databases on the
market today in a highly portable and convenient way.

Unlike our mxODBC Python extension, mxODBC Connect is designed
as client-server application, so you no longer need to find production
quality ODBC drivers for all the platforms you target with your Python
application.

Instead you use an easy to install Python client library which
connects directly to the mxODBC Connect database server over the
network.

This makes mxODBC Connect the ideal basis for writing cross-platform
database programs and utilities in Python, especially if you run
applications that need to communicate with databases such as MS SQL
Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase
ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more,
that run on Windows or Linux machines.

By removing the need to install and configure ODBC drivers on the
client side, mxODBC Connect greatly simplifies setup and
configuration of database driven client applications, while at
the same time making the network communication between client and
database server more efficient and more secure.

For more information, please see the product page:

    http://www.egenix.com/products/python/mxODBCConnect/

________________________________________________________________________

NEWS

mxODBC Connect 1.0.0 is the first general availability release of our
new mxODBC Connect product.

With this release we have further improved the performance and
round-trip times of the mxODBC Connect network layer even more.

We are now able to achieve a *more than 10 times better performance*
for a typical multi-tier application that runs on Linux and connects
to a MS SQL Server database running on a Windows host, compared to the
same application using mxODBC and the FreeTDS ODBC driver.

Thanks to everyone who participated in the public beta !

________________________________________________________________________

DOWNLOADS

The download archives as well as instructions for installation and
configuration of the product can be found on the product page:

[ANN] Pyjamas 0.4: Python Web Toolkit Release

This is the 0.4 Release of Pyjamas, the python-to-javascript
compiler and Web Widget set and framework.

Download Pyjamas 0.4 here:
https://sourceforge.net/project/showfiles.php?group_id=239074
http://code.google.com/p/pyjamas/downloads/list

Pyjamas started as a port of Google's Web Toolkit, to python.
Explaining why Pyjamas (and GWT) is so significant takes
some doing: the summary is that comprehensive desktop-like
user interfaces can be developed very simply, to run in
any modern web browser, without having to write a single
line of JavaScript. Further recommended reading is here:
http://advogato.org/article/993.html
http://advogato.org/article/981.html

The homepage is http://pyjs.org
The sister project, Pyjamas-Desktop, is at http://pyjd.org

Documentation on Pyjamas is considerable, and includes:
  http://pyjs.org/book/output/Bookreader.html
  http://pyjs.org/showcase/Showcase.html
  http://pyjd.sf.net/api
  http://pyjd.sf.net/controls_tutorial.html
  http://lkcl.net/pyjamas-desktop/docs/output/docui.html
Also, as the Pyjamas UI API is near-identical to that of
GWT 1.5, the GWT JavaDoc reference guide is still relevant:
