A simple core.async job system in Clojure
In my off time (and my on time, for that matter) I've been working on this quirky thing I've called Scinamalink (sounds like 'skinamarink'). Scinamalink lets customers send Magic login links to their users with a single REST API call. If you don't know what a magic

Why Lisp Will Never Win (2003)

To avoid confusing this with the real lightning talks sessions, Nat decided to call my talk ``Nine Views of Mark Jason Dominus''.

Why not to use (f)lex, yacc or bison
flex and bison still work, but modern parser generators beat them on Unicode, grammar format, keeping code out of the grammar, and documentation. A point-by-point comparison.
