miscellaneous

Things that are here are not so easy to categorize.

gcolor

Have you ever wanted to know the color of magic? Or the color of absolutely anything? Let gcolor figure it out for you.

fcolor

Have you ever wanted to know the color of something I didn't think of including in the gcolor examples? If Flickr images are good enough for you, fcolor works directly in your browser.

hashlink

A fancy — if useless — space-saving trick for dynamically linked ELF files. Details here.

zem.fi logo

Explanation for the logo/thing on the front page can be found on a separate page.

.xmonad

My personal XMonad configuration is in a GitHub repo. Might be useful if you want an example where a dzen2 bar is controlled over DBus.

OpenTTD logic

A rather old (and possibly outdated) look at how one could simulate digital logic circuits with OpenTTD. Includes the fastest four-bit ripple-carry adder ever: takes about two months (of in-game time) for the carry information to propagate. Document here.

SSH knock

From the 2005s, a nano-HOWTO on how to build a port knocking system to reduce the amount of SSH password guessing attempts, with simple iptables rules and no extra daemons. Document here.

sqrt(-garfield)

I've written a pair of Square Root of Minus Garfield strips.
