Comment [BUZZWORDOFTHEDAY] security system can be hacked (Score 2) 58

It's usually* not [BUZZWORDOFTHEDAY]'s fault, it's usually the fault of incompetent, cheap, or lazy people.

The same thing can happen with yesterday's [BUZZWORDOFTHEDAY] and the same thing will probably happen with tomorrow's [BUZZWORDOFTHEDAY]. Sigh.

*Sometimes it is the fault of [BUZZWORDOFTHEDAY]. In that case, it might actually be "news for nerds," assuming [BUZZWORDOFTHEDAY] is a tech-related buzzword.

I presume that this would be integrated with some kind of app on the receiver end. When the truck is dispatched (or, if the depot is in range, when the parcel is ready for direct dispatch), you'd get a message telling you the time window when it will be available. You then signal that you're ready to receive it and give some GPS coordinates. It's then dispatched and sends another message when it's a few hundred metres away. You then go outside (or stand on a balcony) and wait for it to be delivered directly to you. Once it's very close, it can use WiFi from your phone (send your MAC address to the drone and the SSID that you're associated with - or create an ad-hoc network if you're out of range and it can home in on you) to check that it's actually landing by the correct person. Then just tap the 'delivery received' button and it will fly away.

Unless the parachute can steer it away, I'm not sure it would help much. The speed and momentum that would cause most of the damage would be from the vehicle striking it.

I'm replying from my phone with piss poor reception so i didn't get a chance to watch the video you linked to. Sorry if that already answered my point.

You ended up in the gulag right along with the rightists you helped to put there.

Last June, I was in Sweden and Finland. I looked for gulags and couldn't find any. Maybe they hide them under all the hospitals and universities that are free for everyone.

In the good old USA, on the other hand...


Comment Re:How does space elevator save energy? (Score 2) 127

No space elevator designs that are even vaguely plausible include a moving cable. To understand why, consider the mass of such a cable: the energy required to accelerate it and then decelerate it for the cars to start and stop would be phenomenal. You could potentially have a loop that would continuously move in a circle, but you'd still have problems starting it. Just dropping things from the top wouldn't be enough, because you'd need to get them a fair way down before they'd stop orbiting and actually provide force in the correct direction. I don't even want to think about the lateral forces that such a structure would have to endure.
