QOTW:  "One of the nicest things about the TIP rendering code is that I
manage different output formats by just executing the code version of the
TIPs in different namespaces." -- Donal K. Fellows

"There are no types. Types are bad. Types are the underlying hardware
implementation showing through into the code." -- D. Richard Hipp


POTW:  TclUDP makes UDP programming handy on Windows, Linux, *BSD,
and, soon, MacOS.

    Tcl improves constantly.  While some remote observers sincerely 
    believe it moribund, in fact there's interesting, necessary, and
    sometimes leading-edge (does the larger software world yet under-
    stand stubs or VFS?) work and rework going on every day.  Notice,
    for example, how the low-level progress of Zoran Vasiljevic, Daniel
    Steffen, Jeff Hobbs, and others, apparently having to do only 
    with obscurities of threading under Mac OS, might well result in
    whole new categories of cross-platform capabilities.

    It's not so much that you're going to need to simulate in software
    an old "flip-card" scoreboard, although you'll certainly thank 
    Chris Nelson and Andreas Leitgeb if you do.  The larger point is
    simply what interesting results a very few lines of code can give.

    Don Porter, Helmut Giese, and others illustrate the modern
    alternatives to "big wishes", with the usual consequences for
    those working on unusual operating systems, in embedded
    situations, and so on.

    GUIs are hard to do right.  Everything about them is gnarlier
    than you think.  Even choosing a single color is difficult.

Thanks to Arjen Markus for his report from the Wiki(s):
  Some things old, some things new - it is the usual kind of activity
  on the Wiki ...
  
  Fun with maths 
  - If your kid collects picture cards and has ambition to get the 
    complete set, you may want to try this (French) page to compute
    the financial consequences ... <http://wfr.tcl.tk/955>
  
  - Perhaps it is better to set your kid to this little app and 
    have him/her sharpen his/her arithmetical skills ...
    <http://wiki.tcl.tk/13271>
  
  - For those who already know how to divide and multiply, here
    is a more advanced challenge: understand wavelets - the
    page <http://wiki.tcl.tk/14023> is one of several featuring
    the concept.
  
  Fun with programming
  - Call it webscraping, call it an HTTP robot, the principle 
    remains the same: get a little program to hunt down the
    contents of a web page automatically - <http://wiki.tcl.tk/1303>
  
  - Does Tk have sufficient support for copying and pasting?
    The answer is: it depends - <http://wiki.tcl.tk/14035>
  
  - Communicating with another program via a two-way pipe is
    fraught with details ... or is it? <http://wiki.tcl.tk/14024>
  
  - Your Wiki chronicler will keep silent about this programming
    style - <http://wiki.tcl.tk/14006>
  
  Fun with Tcl
  - Yet another marketing discussion: _we_ know Tcl is a well-kept
    secret, but shouldn't we tell others about this? 
    <http://wiki.tcl.tk/9505> and, as a kind of answer, 
    <http://wiki.tcl.tk/13723>
  
  - No documentation for the source code? You might want to 
    try out some tool to generate it ... <http://wiki.tcl.tk/13009>
  
  - No online help? You might want to try this tool:
    <http://wiki.tcl.tk/3267> - just Tcl/Tk, so no excuse.
    

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