QOTW: "clt is just marvelous - if it didn't exist already, it needed to be invented." - Helmut Giese http://groups.google.com/group/comp.lang.tcl/msg/d7ad9595... "In general, an O(N) algorithm suddenly switching to O(1) in constant space is suspect ;-)" - Alexandre Ferrieux http://groups.google.com/group/comp.lang.tcl/msg/0bf24056... What will you hear at the Tcl 2008 Conference? Ron Fox et al. have already put the abstracts online: http://groups.google.com/group/comp.lang.tcl/browse_threa... Donal, Koen, and others analyze a situation of the performance of variable access that involves something deeper than mere Lisp envy: http://groups.google.com/group/comp.lang.tcl/browse_threa... Quick: what's the value of [string is integer 09]? http://groups.google.com/group/comp.lang.tcl/browse_threa... 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 TÃ©cleux" 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&... Suggestions/corrections for next week's posting are always welcome.
