QOTW:  "[O]ne of the key distinguishing features of Tcl is that it is
massively supportive of variadic calls." - Donal K. Fellows


    Colibri raises important issues about memory management,
    including alignment, use of Tcl on modern 64-bit servers,
    Cloverfield, garbage collection, ...:

Thanks to Arjen Markus for his (mostly) weekly summary of Wiki action:
  The Easter weekend has passed, so we are well into spring/autumn in the
  northern/southern hemisphere. Time for a summary again.
  
  The fascination of weather
  - Create your own animations of the weather patterns that interest
    you: Tcl makes it rather easy - <http://wiki.tcl.tk/19663>
  
  - But not only observed weather can be visualised. Here is a tool
    to deal with information on the predicted weather:
    <http:/wiki.tcl.tk/23170>
  
  Mapping stuff
  - Geographic maps are at least as fascinating as weather. Here 
    is some information on what Tcl can mean in that area:
    <http://wiki.tcl.tk/736>
  
  - Interpret "mapping" generously, and you get a system for
    mapping handwritten formulas to computer-readable ones:
    <http://wiki.tcl.tk/23169>
  
  - And a survey into the realm of Tcl use is a kind of mapping
    too. Have a look at the figures and the accompanying analysis:
    <http://wiki.tcl.tk/23153>
  
  Potpourri
  - Writing your own window manager may not be given to everyone,
    but it is a more than a whim. See for yourself - and read the
    article this page refers to - <http://wiki.tcl.tk/13972>
  
  - Should weather fascinate you, you may also be interested in
    spying on the stars in the nightly sky. Well, that can be
    done in a most Tclish way too: <http://wiki.tcl.tk/17564>
  
  - Just a proof of concept, for now at least: an Easter weekend
    well spent by your Wiki chronicler: <http://wiki.tcl.tk/23148>
  
  - Perhaps more immediately useful, annotations on the canvas:
    <http://wiki.tcl.tk/23156>
  
  - And to conclude: yet another example of the use of coroutines.
    This time to see how they hold in a simulation environment:
    <http://wiki.tcl.tk/23178>
  

Everything Tcl-related you want is probably one or two clicks away in these
pages:
    The "Welcome to comp.lang.tcl" message by Andreas Kupries
        http://www.purl.org/net/tcl-welcome
    comp.lang.tcl is a crucial resource for Tcl practitioners.
    An interesting perspective on its traffic appears at
        http://groups.google.com/group/comp.lang.tcl/about

    The Tcl Developer Site is Tcl's "home base".

    Cameron Laird tracks several Tcl/Tk references of interest (but
    needs to validate many of the links).

        http://www.cetus-links.org/oo_tcl_tk.html

    "Yahoo! Groups" archives comp.lang.tcl.announce posts--even 
    though clta itself is dormant.

We're working on more useful archives of past installments.  Dave 
Williams generously is building up
    http://www.bacomatic.org/~dw/comp/tclurl/index.htm
