Perl/Tk Spreadsheet Editor

This is as far as I could approximate a Perl/Tk UI to Microsoft Excel. No, I don't want to create a clone of Microsoft Excel. But I was interested in how much one could lift the style of the plain old Tk. And I like the look and feel of Excel, so it was kind of inspiration for me.

Where is Brent?

Does anybody know Brent B. Powers, the author of (amongst others) Tk::FileDialog and Tk::Waitbox?

I tried to contact the author my e-mail but every address I tried returned an error like undeliverable or unknown user etc.

Visualizing the McNaugthon-Yamada-Glushkov Construction

Once in a while I poke in my old Perl stuff to find something interesting. Luckily, this is usually the case.

Today, I found a script that draws an annotated syntax tree of a regular expression. The annotation shows the state sets calculated when applying the McNaugthon-Yamada-Glushkov algorithm to construct a finite automaton from the regular expression.

You can read about it in "Bruce W. Watson. Taxonomies and Toolkits of Regular Language
Algorithms. PhD thesis, Faculty of Computing Science Eindhoven

A GUI for CPAN::Mini

After having read yet another tutorial about CPAN::Mini, I once again had the same thoughts:

  • CPAN::Mini is so cool
  • Imagine the use together with CPAN::Mini::Inject and Stratopan!
  • Damn, a configuration file. Where to put it? How do I find it again a month later when I forgot about my minicpan setup? Putting it just somewhere is like undocumented source code. And Windows + configuration files?? WTF!
  • Why can't it just be one of those nifty nice-looking applications like the Github for Windows - simple, easy to use, beautiful? With installers and start men…

Does anybody know Matthias Nutt?

Once in a while, I search the web for Perl/Tk. I'm always happy to find some old jewels. This time, it was keen little rabbit ears, which is a simple ear training program for Linux and Windows. It has a Perl/Tk GUI and comes with good installation instructions.

You can find it here: Keen little rabbit ears.
