why I stick with Tcl." -- Bryan Oakley

Arjen Markus reports on Wiki activity:
A lot of algorithmic stuff appeared last week on the Wiki. This
may seem a bit "dry", but let us look at a few entries:
There are quite a few pages which address the Internet:
- An example of an HTTP robot appears at <http://wiki.tcl.tk/1303>;
- Hidden in a more general page about the Tcl's interp statement is
the answer to a question that was raised on the newsgroup:
automatically downloading and running code - <http://wiki.tcl.tk/1477>;
A small receipe with indications of what to do if you can not rely
trust the code (answer: use a safe interp!)
- Ever dreamt about the wonders of a worm-hole? Well, "burrow" comes
close: <http://wiki.tcl.tk/3929>; describes the creation of a TCP/IP
tunnel between two hosts, using nothing but Tcl.
- Getting tired of spam? Spam filters may help, one using statistical
techniques is based on other work (see the references contained in
the page, <http://wiki.tcl.tk/3901>;
As the author of this Wiki page, says: enjoy!
Two pages that address graphical user-interfaces:
- XML may or may not be the ultimate solution to all of your
data exchange problems. But have a look at XML files with a
simple browser! <http://wiki.tcl.tk/3884>;
(Actually: it is an example of how to combine the many facilities
that Tcl offers)
- So much function in so little code, <http://wiki.tcl.tk/1913>; presents
a notebook application.
Another two pages, these address interfacing to the system:
- Expect is one of those applications that surpasses the imagination
of many of its users. Try and follow the links (but be careful):
<http://wiki.tcl.tk/3913>; leads to a wealth of information and
then try the other Wiki pages on Expect!
- <http://wiki.tcl.tk/3643>; describes a package that lets your application
know that the contents of a directory have changed.
Well, this leaves a number of pages for which I could not think of
an appropriate subject, other than "techniques":
- The idea of a scripted compiler (<http://wiki.tcl.tk/3687>;) has led
to several pages, including one on parsing C code,
- An application of the msgcat package, universal greetings
(<http://wiki.tcl.tk/2938>;) are everyday's reality in the Tcl'ers chatroom
- Analysing programs (predicting performance for instance) can sometimes be
done by making a small simulation - <http://wiki.tcl.tk/3923>; has an
- Calculating the frequency of substrings is one fundamental subject
in encryption/decryption techniques. This page, <http://wiki.tcl.tk/3838>;,
shows that it is not that hard to do.
Everything you want is probably one or two clicks away in these pages:
