Donal K. Fellows

"If I was the type of person to get nightmares at all easily, deployment

insomnia-through-terror..."  -- Donal K. Fellows

The Wiki's abundant weekly riches make representative selection difficult.
These pages most recently jumped out at Arjen Markus:

    This week there is music in the air and tones that were thought to be
    history:
    - Play piano at  
    - Or if you are not musical, try to learn the venerable Morse alphabet
      presented in Tk-form at 
    
    Drawing typically means:
    - Plotting data, which, as  shows, can be done
      with lots of different packages 
    - Something almost artistic, you could think of cellular automata, a 
      famous example is Conway's "Life", and now a simple script, 
      , is available to get you started
    - Anything that can be put on a whiteboard, as a demo shows that arose
      in the Tcl/Tk chatroom, .
    
    Drawing and graphs are not the same, as graphs frequently refer to 
    data structures. Various approaches to handling such data structures
    are presented in . Just have a look!
    
    New and practical techniques are presented in the following pages:
    - Clean up when you are done with the application, AtExit handlers do
      the job, 
    - Who says Tcl does not have "closures"? Look at a practical application,
      
    - If you need to develop an expert system, CLIPS is public domain tool,
      with a Tcl interface, just follow the path from 
    - Printing (PostScript) under Windows, from within Tcl, is made simple,
      by the techniques described in 
    - Wrapping your scripts into a Starpack, the latest method of distributing
      a Tcl application, is described in
