QOTW:  "clt is just marvelous - if it didn't exist already, it needed
to be invented." - Helmut Giese

"In general, an O(N) algorithm suddenly switching to O(1) in constant
space is suspect ;-)" - Alexandre Ferrieux

    What will you hear at the Tcl 2008 Conference?  Ron Fox et al.
    have already put the abstracts online:

    Donal, Koen, and others analyze a situation of the performance of variable
    access that involves something deeper than mere Lisp envy:

Thanks to Arjen Markus for his weekly summary of Wiki action:
  Funny how some topics seem to be "in vogue" on the Wiki. This week
  we can see a lot of pages on "coroutines". But do not despair:
  a lot of pages on sundry other subjects as well.
  
  What coroutines are all about ...
  - Two pages on coroutines should help to get an idea of their use:
    - <http://wiki.tcl.tk/20662> introduces the concept of 
      coroutines and closures, using standard Tcl
    - <http://wiki.tcl.tk/21532> elaborates the use of coroutines
      in the context of Tk GUIs and fileevents.
  
  - A lightweight multithreading facility which could be used
    for coroutines too is at <http://wiki.tcl.tk/15248>
  
  You did not know this, right?
  - Tcl has a well-hidden set of commands, commands that are
    strange, experimental, etc. They are now revealed at
    <http://wiki.tcl.tk/21444>
  
  - One of them is "disassemble": get some insight in the 
    workings of the Tcl byte code compiler and engine:
    <http://wiki.tcl.tk/21445>
  
  - But the "new" apply command can also be used for 
    yet another object oriented system: <http://wiki.tcl.tk/21514>
  
  - Printing extra output is an age-old debugging method. And
    this page shows it can be done so elegantly ...
    <http://wiki.tcl.tk/15995>
  
  Other stuff 
  - If you are interested in artificial intelligence, you may
    find the links on this personal page of interest:
    <http://wiki.tcl.tk/21458>
  
  - And for just one AI technique, genetic algorithms, you may 
    find the interface to a particular library useful:
    <http://wiki.tcl.tk/3020>
    
  - Can we improve the console in tclsh and wish? What ideas
    do you have about it? <http://wiki.tcl.tk/21523>


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".
	http://www.tcl.tk

    Larry Virden maintains a comp.lang.tcl FAQ launcher.
        http://www.purl.org/NET/Tcl-FAQ/

    The Tcl Developer Xchange is a highly organized resource center
    of documents and software with provisions for individuals to
    maintain references to their own software:
        http://www.tcl.tk/resource/
    The TDX sponsor, ActiveState, also keeps info to convince your
    boss Tcl is a good thing
        http://www.tcl.tk/scripting/

    The Tcl'ers Wiki is a huge, dynamic, collaboratively edited repository
    of documentation, examples, tutorials and pontifications on all things 
    Tcl.
        http://wiki.tcl.tk/0
    For the ideal overview of the topics about Tcl most likely to
    interest a newcomer, see "Arts and Crafts ..."
        http://wiki.tcl.tk/969
    There's also a high-quality Wikibook on Tcl:
        http://en.wikibooks.org/wiki/Programming:Tcl

    ActiveState maintains binaries distribution and development tools
        http://www.activestate.com/Tcl
    along with a Cookbook of Tcl recipes
        http://aspn.activestate.com/ASPN/Cookbook/Tcl

    "La Gazette du Técleux" is an important monthly publication.
	http://wfr.tcl.tk/1159

    deli.cio.us presents an intriguing approach to reference commentary.
    It already aggregates quite a bit of Tcl intelligence.
        http://del.icio.us/tag/tcl

    Cameron Laird tracks several Tcl/Tk references of interest (but
    needs to validate many of the links).
        http://phaseit.net/claird/comp.lang.tcl/

    Years ago, Cetus Links maintained a Tcl/Tk page with verified links
        http://www.cetus-links.org/oo_tcl_tk.html

    "Yahoo! Groups" archives comp.lang.tcl.announce posts--even 
    though clta itself is dormant.
        http://groups.yahoo.com/group/tcl_announce/

We're working on more useful archives of past installments.  In the
meantime, an alternative is
