FOSDEM 4: Feb 2004
The Fourth FOSDEM was held once again in Brussels. A dozen or so hard-core Tcl'ers attended and presented how-to papers describing how to use Tcl in common and uncommon ways and introduced Tcl/Tk to several newcomers.

  • Clif Flynt presented an introduction to Tcl/Tk and a discussion of the C API to Tcl.
  • Arjen Markus described clever techniques for using the text widget.
  • Theo Verelst demonstrated B-Wise, a block oriented programming technique written in Tcl.
  • Jeff Hobbs discussed the current (Active) State of Tcl.
  • Reinhard Max demonstrated how easy it is to write a client-server application in Tcl by developing a chat server while we watched (Clif Flynt and Donal Fellows developed clients for the server as the protocol was defined.)
  • Peter.DeRijk described ClassyTk, an object oriented approach to creating Tk applications.

It was a good chance for folks to meet and chat. We intend to return to FOSDEM with a more organized presence next year.

Programming Paradigms with Tcl
Tcl/Tk can be used in many ways, as a scripting language, as an application glue language, or as an interpreter library to be embedded in a compiled application.

This white paper describes the same application developed in different paradigms, as a standalone Tcl/Tk application, as a Tcl/Tk application extended with compiled code. as a wrapper for a "C" language application, and as a compiled application with the Tcl/Tk interpreter embedded.

Rubicon 4
Rubicon 4 is a computer conference for security experts on both sides of the equation, the attackers and the defenders. The presentations I listened to were excellent, discussing topics that ranged from the history of BBSs to tutorials on firewall configuration, explanations of elliptical curve cryptography and passing drug tests.

It's received positive reviews from many readers.

Dr. Dobbs Electronic Review says: ...Flynt has produced what must be the quintessential Tcl/TK pedagogic presentation. The print book is first-rate technical writing. ...
