Jim's OSS contributions

My contributions to the Open source movement.

As you can see, there's not much at the moment, but I will keep plugging away, and will add to this as I can.

A data visualization aid for text symbol frequency

I wrote this to do some data visualization on encrypted, ascii armored pgp files. Pass it a filename, and it outputs a postscript file showing a spray of symbols, the further away from the center, the more frequent the symbol is used.

Python program to grab maps from US Census Tiger database

A small program to grab maps from the Tiger database operated by the Census department. It's crude, it's crufty, it's free, and you can get it here


Python paragraph formatter

A short bit of python that takes a bit of text, that has paragraphs delimited by one or more blank lines, and wraps them in <p><\p> tags.

mpac, the Microwave patch antenna calculator. I didn't write this, but I submitted a couple of patches to the author, who I have been unable to contact for some time. I put this up here so that it won't vanish from the ken of man, but I make no claims to it's ownership. I do *not* have the copyright, and can only put it up here because it is open source software. If the author would like to contact me, I will gladly remove it for them to maintain again, or whatever. I found this tool quite useful, but I want no-one to be under any illusions about who wrote it.

Mpac was written by Nathan Cummins. I have no valid e-dress for him.

At some point, there are some mods I would like to make to this, but they are low on a long list of stuff I need to do.
