Today I learned…

1. there's a card game where you complete a task from Unix pipe commands: punkx.org/unix-pipe-game/ (via mamot.fr/@bearstech/1142758430)
2. there's a JavaScript x86 machine emulator so you can play that game without needing a real computer around: bellard.org/jslinux/tech.html
3. that JS VM gets network connectivity because someone decided to make a websocket-based VPN that passes Ethernet frames: benjamincburns.com/2013/11/10/

I've made a fraction-based calculator, for simplifying rational expressions (written in ANSI-C using vi)

I was aiming to merge a scientific calculator with "bc", because I often need to simplify various fractions and whatnot. Quite happy with the result!

Uses shunting yard algorithm to evaluate the expressions, and a naive descent parser (I think?) to tokenise

Aside: OpenBSD's "editline" is very easy to use

Please ask any questions :)

The Xerox PARC alumni who contribute to the Medley Interlisp project shared the buttons they collected at computing conferences in the 1980s and 1990s such as AAAI, IJCAI, SIGGRAPH.

The buttons are awesome and span a range of languages and systems such as Interlisp, Lisp Machines, Smalltalk, Unix, Modula-2, Mesa, Pilot, and more. Be sure to go through the whole thread.

You Have Installed OpenBSD. Now For The Daily Tasks.

Despite some persistent rumors, installing OpenBSD is both quick and easy on most not too exotic hardware. But once the thing is installed, what is daily life with the most secure free operating system like?
