Brendan Eich on Ecma TC39, JavaScript.next, and Google Dash
I spoke at TXJS , a really excellent regional JS conference, in June. Thanks to @SlexAxton , rmurphey , and everyone else involved.

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''. At first I didn't like that title, which sounded too much like self-promotion. But I warmed up to it after a…
