Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
We already require extra authentication at a distance to arm nuclear weapons, and last season's 24 notwithstanding, we routinely operate military drones at a distance. Reportedly in the Falkland Islands war, Margaret Thatcher was able to extract codes to disable Argentina's Exocet missiles from the French. The simplest implementation might be like the proposal for land mines that expire after a certain time. Perhaps tanks — currently usable without even an ignition key — could require a renewal code digitally signed by the owning country to be entered manually or received by satellite every six months or so.
I'm a skeptic of kill switches, especially in consumer devices, but still found myself writing up the case for a way to disable military hardware in the field. There are lots of reasons it might not work — or work too well — but is there a way to improve on what we face now?
However, it's likely that Facebook isn't entirely to blame for this kind of trend, but rather, with the debut of its auto-play feature, threw gas on an already growing fire of video-sharing services. Auto-play for video is a default setting on Instagram's app, although the company refers to it as "preload." Instagram only introduced video last summer, after the Vine app, a Twitter-backed app that auto-plays and loops six-second videos, started to see significant growth.
