PaperBack is free software which enables you to print data onto paper and read it back in via a scanner. With a 600 dpi printer and a 900 dpi scanner it is possible to store ½ megabyte of data per letter page; with compression, it’s possible to store about 3 megabytes per page (depending on the source data, of course — his example uses C code).
This is actually kinda cool: you could print out a few hundred pages and replicate the data on a CD; esp.

On Friday I started playing around with MoinMoin Desktop Edition; it’s a personal wiki. The idea is that it can act like a free-form personal information manager. Playing around, it looks pretty neat; I’ll be using it over the next month or two and will see how it actually works out in practise.

Michael Wiedmann has a great reference for screen presentation (e.g. PowerPoint) tools which focuses on those which run on open platforms (and maybe Windows/Mac OS X as well).

Inkscape is a nice little vector graphics editor derived from Sodipodi, which was itself derived from gill. Looks very featureful and pleasant to use.

Maxima is a cool symbolic algebra system based on software which has been around since the 1960s and which has been continuously updated since. Available under the GPL, it has survived even the death of the maintainer. Very cool, if math is one’s thing. And neat no matter what.
