QOTW: "If you are using pack, don't - a megawidget should NEVER use
pack.  You'll be more flexible and efficient with grid." -- Jeff Hobbs

"args, how I hates magic variables.  I don't env ee those perl
programmers." -- Donald Arseneau


POTW: Rivet 0.3 by David  Welton and the Rivet Team.  "Rivet is a
system for web programming based on the Apache web server and the
Tcl programming language".  "The most exciting thing about the new
code is the new Session code".

     Monitoring a fixed-size file of state information for changes,
     when you have no control over the writing process:

     Should you write your new megawidget in pure Tcl, object-
     oriented Tcl, or C?  Here are some opinions and tips:

     Detecting a click on the titlebar is complicated by the inter-
     action between the WM, the focus model, and Tcl:

     A canvas can accept coordinates in the units of your choice,
     but can it report them that way as well?

     Using variables in [format] conversion specifiers:

     "Language X has this, why doesn't Tcl?"  Well, Tcl may have
     the concept but not the construct... it may have a better one!

Thanks to Arjen Markus for his summary of Wiki activity:
  A small bouquet of diverse flowers from the Wiki, mostly very fresh,
  and one venerable, yet vivid:
  
  GUIrlandes: 
  - You want to have tooltips with your GUI? Go here first and move
    on to the appropriate solution: <http://wiki.tcl.tk/1954>
  
  - Toplevel windows can do more than just contain subwindows, they can embed
    other toplevel windows, sometimes even from a different program
    - <http://wiki.tcl.tk/10887>
  
  Technicolored flowers:
  - Translating words into integers and the other way around might be useful
    for encoding, encryption, obfuscation ... Anyway, have a look at 
    <http://wiki.tcl.tk/10915> 
  
  - Set operations, they may seem trivial, but they are at the heart of 
    many a computer program. Here is a bit of fun, <http://wiki.tcl.tk/10914>
  
  - Want a different kind of sets? Try "rough sets", <http://wiki.tcl.tk/10884> 
  
  Noli-me-tangere:
  - Two license agreements for the Wiki, <http://wiki.tcl.tk/10892> and
    <http://wiki.tcl.tk/10898>
  
  Linguistic borders for everybody's garden:
  - An implementation of a Forth-like language in Tcl,
    <http://wiki.tcl.tk/10870>
  
  - A completely independent approach to "reverse Polish notation" -
    <http://wiki.tcl.tk/10913>
