Everything Is Broken

Facebook and Google seem very powerful, but they live about a week from total ruin all the time. They know the cost of leaving social networks individually is high, but en masse, becomes next to nothing. Windows could be replaced with something better written. The US government would fall to a general revolt in a matter of days. It wouldn’t take a total defection or a general revolt to change everything, because corporations and governments would rather bend to demands than die. These entities do everything they can get away with — but we’ve forgotten that we’re the ones that are letting them get away with things.

The 60,000 feet bug

ATC, air traffic, bug, computers, error, glitch

On Wednesday at about 2 p.m., according to sources, a U-2 spy plane, the same type of aircraft that flew high-altitude spy missions over Russia 50 years ago, passed through the airspace monitored by the L.A. Air Route Traffic Control Center in Palmdale, Calif. The L.A. Center handles landings and departures at the region’s major airports, including Los Angeles International (LAX), San Diego and Las Vegas. The computers at the L.A. Center are programmed to keep commercial airliners and other aircraft from colliding with each other. The U-2 was flying at 60,000 feet, but the computers were attempting to keep it from colliding with planes that were actually miles beneath it. Though the exact technical causes are not known, the spy plane’s altitude and route apparently overloaded a computer system called ERAM, which generates display data for air-traffic controllers. Back-up computer systems also failed.

Multics Emacs History/Design/Implementation

emacs, multics, paleocomputing, history, computing, computers

Multics is no longer produced or offered for sale; Honeywell no longer even makes computers. People edit on computers on their desktop so cheap and fast that not only do redisplay algorithms no longer matter, but the whole idea of autonomous redisplay in a display editor is no longer a given (although autonomous redisplay’s illustrious child, WYSIWYG, is now the standard paradigm of the industry.). There is now no other kind of editor besides what we then called the “video editor”. Thus, all of the battles, acrimony, and invidious or arrogant comparisons in what follows are finished and done with, and to be viewed in the context of 1979 – this is a historical document about Multics and the evolution of an editor. It is part of the histories of Multics, of Emacs, and of Lisp.
