<pre>QOTW:  "Tcl is not programming, it's a lifestyle." - Mark Janssen


Thanks to Arjen Markus for his weekly summary of Wiki action:
  No time to waste - let us move on to the summary proper!
  
  Science
  - Experimenting with algorithms never hurts. So why not a classical
    algorithm to find the shortest path in a graph using a classical
    OO extension? <a href=wiki.tcl.tk/21325>wiki.tcl.tk/21325</A>
  
  - And as we are experimenting, suppose you did not have a full 
    complement of mathematical functions in your expr command, but
    did have "Abramowitz and Stegun" - you can still do maths!     
    <a href=wiki.tcl.tk/21322>wiki.tcl.tk/21322</A>
  
  - Let us get extreme: what if we had no commands or variables at all? 
    This would be the perfect environment to get configuration parameters:
    <a href=wiki.tcl.tk/21319>.wiki.tcl.tk/21319</A>
  
  Fiction
  - If you want to create your own text adventure game, several options
    exist. The latest one is nicely object-oriented: 
    <a href=wiki.tcl.tk/21324>wiki.tcl.tk/21324</A>
  
  - If you need to pay a bill, you may need to check a number ...
    Here is an algorithm for the BPay system - <a href=wiki.tcl.tk/18143> wiki.tcl.tk/18143</A>
  
  - If you need to come up with a number for the German Personalausweis
    system, may be this page is what you are after:
    <a href=wiki.tcl.tk/21317>wiki.tcl.tk/21317</A>
  
  Past, present and future
  - Did you ever realise that an IDE as massive as MS Visual Studio
    could be tamed with Tcl? Well, it is a small part only, but still,
    it is a start: <a href=wiki.tcl.tk/21314>wiki.tcl.tk/21314</A>
  
  - Tail call optimization - reduced memory footprint - cheaper recursion:
    it is all there in a three-letter acronym: NRE. For those 
    who can not wait: <a href=wiki.tcl.tk/21320>wiki.tcl.tk/21320</A> but also
    <a href=wiki.tcl.tk/20861>wiki.tcl.tk/20861</A> for the technical background.
  

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
  http://groups.google.com/groups?oi=djq&as_q=+Tcl-URL&as_ugroup=comp.lang.tcl

Suggestions/corrections for next week's posting are always welcome.
