The varying contents basically reflect some of the author's interests, just as you would expect.
The topical folders below are the result of an effort to label them by subject.

Update:
This site has now become quite "mature"; in fact it hasn't changed much since 1996!
Back then a typical monitor size would be 480 x 640, while modem speeds were 14.4 or 28.9 Kbps. So page layouts had to be narrow, all content static, and any graphical elements really small in order to load resonably fast.

Anyway, as from 2017, this site is being served from a diminutive Raspberry Pi computer, housed in a candy tin box which sits quietly in my bookshelf.
