Advent of Computing

Binary is synonymous with digital computing. But is it the only way to crunch numbers? The short answer is no. The long answer, well, that's today's topic. Today we are talking about ternary, aka base 3. From it's early uses in the 19th century, to actual computers, and even theoretical designs; ternary proves to be a difficult topic to track down... and a very unique one.

It's no secret that I've been fascinated by odd UNIX clones for a while. When I got invited back to speak at VCF West this year I decided to share that fascination with a captive audience. In this talk we look at Idris and CROMIX, and ask the simple question: why would you want UNIX free UNIX?
VCFed will be posting the video version of this presentation in the coming weeks. I'll add a link here once that's up.

In 1950 Northrup unveiled their MAgnetic Drum DIgital Differential Analyser. The machine is a wild piece of technology; a rendering of an analog computer in digital encoding. But how did we get here? How did a project to guide a missile lead to a mass produced computer? And what does it have to do with suspiciously dry martinis?

EMUL-8 is a fascinating programming language. It's described in just one paper from 1977. It's a mix of features from APL, LISP, ALGOL, and SNOBOL. And, I think, it's a wonderful window into how counterculture and home computing collided.

I mean that both in the specific and the abstract. This episode we are looking at APL, which stands for A Programming Language. APL was developed in the mid 50s, but didn't see a working implementation until 1965. It's a language that truly looks like no others, but has some odd parallels to everything from BASIC to LISP to linear algebra.
