QOTW:  "When I deal with threading, I work on the principle that the
hardware and OS are my enemies and hate me, and so I code accordingly.
It probably doesn't make for a maximally-efficient program, but it does
reduce debugging pain." --Donal K Fellows

"A failed engineering consensus is a poor reason to add configuration
options.  (For me, one of the beauties of Tcl is that it 'Just Works',
and I don't have to spend hours babysitting its configuration.)

Life is full of tradeoffs."  --Kevin Kenny

    Catch up with Jeffrey Friedl's ruminations on "What's New
    with Regular Expressions".

    Jeffrey Hobbs and others contribute to a technically-involved
    thread detailing Tcl_HashTable changes and 8.3 / 8.4 binary
    compatibility issues induced thereby.

    George Peter Staplin updates his megawidgets contributions:
    Cscrollbar and Ctext.

Thanks to Arjen Markus for his summary of Wiki action:

    More pages on the Wiki every week!  Now we have:

    Complete applications and libraries:
    - The plot package Plplot is described in <>;
      It is the underlying library for many applications and an interface
      to Tcl/Tk is readily available.
    - If you need to deal with directed acyclic graphs, why not try the
      following pages:
      <>; contains the Tcl code for handling the graphs
      <>; has procs to read and write the Graphviz format
      that is suitable for storing such graphs
      and <>; completes it with examples
    Some Windows-specific pages:
    - Browsing through the dreaded Windows registry,
      <>; tells you how
    - Should you feel the need to make a Tk application with a
      multiple-document interface, then stop and visit
      <>;. We leave it to the reader whether that
      is a wise decision :-)

    Bits and pieces:
    - Games can be fun with and without pictures. An engine for text-based 
      adventures by Larry Smith, <>; 
    - Editing date and time in a GUI can be tricky, 
      <>; needs some more work to cover the various
      formats used around the world.
    - Just a small but practical script to handle and display a set of data,
    - A nice little method for searching in a multilevel list, started by 
      Richard Suchenwirth, optimised by Michael Schlenker, cooperation  
      par excellence, <>;.

Everything you want is probably one or two clicks away in these pages:

    is a good thing      

    The Tcl'ers Wiki is a huge, dynamic, collaboratively edited repository
