Sketch 0.6.13

Sketch stable 0.6.13 released

			Sketch is closest to the goal of becoming an 
			universal drawing application for GNU/Linux [...]
			(LinuxUser 9/2001, pp 40, translated from German)

This latest release of the leading Free Software Vector Drawing application,
fixes a minor security hole and adds often requested multi-line text handling.

	http://sketch.sourceforge.net/

Everybody running a stable sketch version should upgrade to 0.6.13.
Note a new way of contributing to Sketch through minipayments (see below).

Bernhard Herzog, March 2nd, 2002

	What's new
	==========

* Multi-line Text Handling

	The multi-line plugin contributed by Christof Ecker makes
	designing covers and posters with Sketch a lot easier.
	It is now possible to insert and independently edit
	complete text blocks. Through the modular design of 
	Sketch's data-format, the resulting files can still be edited
	with earlier versions of Sketch.

	This nicely blends in with the curvetext and geoobject add-ons 
	to bring you a more complete set of functionality

ANN: lfm 0.8

Hello, 

I've uploaded lfm v0.8 on its web site: 

http://www.terra.es/personal7/inigoserna/lfm

[With this release, I have finished all the features I want for lfm, 
so I hope to release v1.0 in May. These 2 months will be spent fixing bugs
and maybe adding features people want. Nevertheless current version is very
robust and stable, I use it daily without problems.]

lfm is a 'midnight commander'-clone written in Python and licensed under
GNU Public License. It should work on any UNIX with a modern (n)curses
library and Python curses module compiled in. See README file or visit
the web page for more information. 

Changes since version 0.7: 

Version 0.8 ("Close to Paradise") - 2002/03/04:

  + Implemented VFS feature to enter into .tar.gz and .tar.bz2 files
  + Panelize vfs option in find/grep implemented
  + Tree panel implemented
  + 'lfm' and 'pyview' are simple scripts now, not just a copy of the .py files>    __init__.py contains global
variables now
  + A new message window is used to show  work in progress, in place of a
    message in status bar. 'run_thread' function has been cleaned too
  + Copy / move features now use my own function to walk trees, instead of
    'shutil.copytree' which originates some problems and bugs
  + In ChangePermissions window, the cursor movement is circular now

ANN: VideoCapture 0.7 released

VideoCapture-0.7
================

URL:
----
http://stud4.tuwien.ac.at/~e9326522/VideoCapture/

What it is:
-----------
VideoCapture is a Python extension for Win32 which makes it possible
to access video-capture devices (e.g. a USB webcam, a TV-card, ...).

What is new in version 0.7:
---------------------------
*) Replaced the .gif fonts by .png fonts, since PIL shows a memory leak
    when using .gif fonts.  Remove the files 'helvB08.gif' and
    'helvetica-10.gif' in the Lib folder of your Python installation if
    you have used a version of VideoCapture prior to 0.7!!

*) Replaced displayPropertyPage() by displayCaptureFilterProperties()
    and displayCapturePinProperties().  This finally allows selecting
    things like the video size used during capturing for every kind of
    device-drivers (now also for WDM drivers, previously only for VfW
    drivers).

*) Since there were some memory-leak issues with some device drivers
    when the filter graph was started and stopped for each capture, the
    graph is now continuously running.  Beside the solved memory issue
    this has the big advantage, that taking snapshots can be done
    *really* fast now.  Taking 10 and more snapshots per second is no

Python SOAP libraries - With and without WSDL

IBM developerWorks released it second article on Python and SOAP:
Continuing their look at Python SOAP implementations, Mike Olson and
Uche Ogbuji put the Zolera SOAP Infrastructure (ZSI) through its paces
as a SOAP client and server library. They find that ZSI is possibly
the best tool for SOAP use under Python right now.

ANN: Python Spread Module 1.1 Released

I've released version 1.1 of the Spread Module for Python.  Tadaaa:

    http://www.python.org/other/spread/

Changes since release 1.0
-------------------------

- The README recommend using 3.16.2rc1 or later.

- Using Spread 3.16.2, it now works on Windows.

- Changes to the test suite to make it less accident-prone.

- Fixed race conditions having to do with disconnects in
  multi-threaded programs.  When one of the errors CONNECTION_CLOSED
  or ILLEGAL_SESSION is received, mark the mbox as closed.  In
  addition, use a lock to serialize access to the disconnected flag.

- Fixed a memory leak that leaked about 50 bytes per mbox.receive()
  call.

Enjoy!
