Not just LED lights, but LEDs in general, one of the most indestructible pieces of modern technology. If you have a device with an LED, chances are one of the last things to fail will be the LED. My LED-backlit computer monitor is still going strong after three years. Contrast that with the back light of my previous non-LED LCD monitor which I had to replace twice or the flickering picture tubes of my earlier CRT monitors.

I'm even more impressed with the toughness of the LED light bulb I bought last year, which I stupidly dropped twice from a +7ft height. The LEDs were housed inside a frosted plastic cover. When I dropped it the first time, the cover came off, which I just snapped back on. The second time I dropped it, I managed to break the cover. Now I'm running the LEDs naked, which makes the light kind of brighter and harsh only if I stare at the ceiling for a long time.

I'm not a woolly mammoth, but the release name sounds really gooey, very easy for critics to pan the release in case something goes south: my Trusty Tar install got stuck at the boot logo.

More like the Google Glass of money. Opinions about Segway have never been as polarized as opinions about Bitcoin.

Okay, here's a link to the blog cited by the PopSci article. The blog appears to contradict the summary that the Russians were alone in developing these primitive robotanks:

There were similarly designed tanks also in the German army. There was the teletank V-4, there were small anti-tank “torpedoes” such as the radio-guided “Springer” and the “Goliath”, which would unwind an electrical control lead behind itself. A “Goliath” is found in the armoured vehicle museum at Kubinka. It is difficult to consider all of these designs as being successful. It was very difficult to direct a “Goliath” up to a tank even from a distance of 100 meters. The battery had a charge, which allowed for only eight minutes of movement, and the low clearance did not provide for sufficient mobility. Equipping these tankettes with a petrol engine did not save the situation. Nevertheless, they were able to carry out certain functions – including mine clearing and attacking fortifications.

The Russians tanks had the advantage in having a longer autonomous range, as the German tanks appear to be wired ("unwind an electrical control lead") rather than radio-controlled.
