It’s time to free JavaScript
You have long ago abandoned the JavaScript trademark, and it is causing widespread, unwarranted confusion and disruption. JavaScript is the world’s most popular programming language, powering websites everywhere. Yet, few of the millions who program in it realize that JavaScript is a trademark you, Oracle, control.

Elites Could Shape Mass Preferences as AI Reduces Persuasion Costs
Abstract:In democracies, major policy decisions typically require some form of majority or consensus, so elites must secure mass support to govern.

Euler Conjecture and CDC 6600
MarDie: it’s also possible to compute the integer fifth-powers at compile time.
