QOTW:  "[T]o reinvent TeX in a few hours is not that simple ;-)" - Richard
Suchenwirth
    http://wiki.tcl.tk/3819

"I'm really liking the use of dicts to store partially processed http
requests, and treating the handling of http requests as a process of
transforming the dict and then serializing it to the socket.  I get
many of the benefits of object-like encapsulation without feeling
guilty about overhead.  I've got all the processing metadata stored
as -elements, and I can just throw in another piece of metadata ad
hoc, if it feels like it might be useful.  AND I can use
[return -request $dict] for exception handling, which is extremely
useful and powerful." - Colin


POTW:  "Growl is a notification system for Mac OS X:  it allows applications
that support Growl to send you notifications."  There's a binding for Tcl.

    David Gravereaux corrects messages sent on exit to the Windows OS,
    and recounts a bit of the history of related errors.  The thread
    nominally focuses on signals and Windows services.

    Roy Terry explains bgerror and "the big catch".  Errors need to be
    understood, of course.

    Donal Fellows sketches a mostly-imperceptible bump in DWIM EIAS:
    Tcl's UTF-8 is slightly denormalized.  We believe that the only
    true liability "is that C code that wishes to work with a bytestream
    can't ... just grab the bytes ..."  Bugs in this area will receive
    expert attention.

Thanks to Arjen Markus for his so-accurate summary of Wiki activity:
  The year will end in less than a week, so this will be
  one of the last summaries in 2005 ... No time to waste 
  then!
  
  Graphics
  - Annotating a photograph in Tcl is not that hard,
    as shown in <http;//wiki.tcl.tk/15163>
  
  - There are many little drawing programs to be 
    found on the Wiki, here is one especially for
    this time of year: <http://wiki.tcl.tk/15176>
  
  - Should you not like Christmas, maybe this 
    animation will help you get into a better 
    mood - <http://wiki.tcl.tk/15178>
  
  - And for the insatiable: viewing three-dimensional
    objects is a piece of cake - <http://wiki.tcl.tk/15084>
  
  - Serious now, a widget that looks like a meter ...
    <http://wfr.tcl.tk/1038> - yes, on the French Wiki.
  
  Numbers
  - Your chronicler is getting old, he had completely
    forgotten about this page - <http://wiki.tcl.tk/10490>
    deals with alternative formatting of numbers, among
    other things.
  
  - An alternative way of computing with "real" numbers 
    - down with the binary system! Well, sort of.
    <http://wiki.tcl.tk/15166> deals with ordinary
    well-behaved decimal numbers.
  
  Paradigms
  - Why stick with the need to prescribe computations in
    detail? Just ask what you want and it will be given
    - <http://wiki.tcl.tk/15157>
  
  - Never forget about other languages ... They may
    hold hidden treasures - <http://wiki.tcl.tk/11025>
  
  
Everything Tcl-related you want is probably one or two clicks away in these
