Slashdot videos: Now with more Slashdot!
You're right that a timer's a bad idea for your use-case, so how about something else? This seems simple enough, if a bit simplistic:
You've always got your smartphone with you, or most people do - certainly just about anyone who would have any interest in the "smart home" market, I would think. In any case, put the phone to work in the *right* way: there are apps that use the radio in the phone to triangulate its position to within a few dozen meters based on cell towers and neighboring wifi hotspots. Make another such app, or hook into an existing one, adding a function to calculate line-of-sight distance from your phone to your house's coordinates on the map.
At home, your smart-home controller would have a live, secure connection to a central server of some kind, waiting for commands.
* Triangulate the phone's position once per minute, in a background task.
* At each interval, if the location resolves to within some "close enough to the house" distance, say 5 miles, send an event the main part of the app.
* That event would cause the app to make a secure connection to the aforementioned server, over which it would send a single "power up the climate control, lights, etc" packet. The triangulation event would then be set to, say, 1 hour.
* The app also could listen for an event from the triangulation routine for "leaving home" also, with a threshold that's a bit more distant than the "coming home" value, say 6 miles. The triangulation interval would reset to 1 minute and a "turn everything off" packet would be sent at this point.
Options to immediately send "power up now" and "power down now" packets (setting appropriate polling intervals in either case) could be offered.
Such an app should show a clear indication of its distance calculation and what the last command was that was sent, and if possible, some status info from the house's controller.
So they'd have shells then?
Same reason I never understood the "Gold Pressed Latinum" nonsense. Even if you couldn't replicate it, what would you buy with it? Everything is free.
Because not every culture used replicators to the same extent as Federation cultures did. Remember who were the biggest proponents of latinum-based economics? The Ferengi, who were all about gaining wealth by pretty much any means; their entire culture is built around gaining material wealth. A replicator needs feedstock in addition to energy, and those don't necessarily HAVE to be free.
Voila, there's your money-based economy in the face of replicator technology.
Backups. Lots and lots of backups. Too bad I *just* bought a 2 TB disk for that purpose a few days ago.
Better a well-maintained coal plant emitting scrubbed gasses than a thousand poorly-maintained gasoline cars belching out exhaust fumes with little more than a catalytic converter to help out.
Except....that a black home has a bottom. There's nothing infinite about them, except in some formulas (i.e. the _mathematical_ singularity at the center). If the black hole is big enough (around 150 billion solar masses), you could even stand more or less comfortably on its surface, normal earth-like gravity, provided the radiation doesn't kill you.
If the values are straight storage, well that's an extra 4 bytes per video for the count. Some quick googling turns up a couple of figures that aren't too terribly old, and which don't actually add up to much:
As of 2008, there were around 83M videos on YouTube, so that's 332 MB for storage for the counters, assuming every video's record were updated and the count data is stored uncompressed. I'd guess double that amount for 2014, but I couldn't find a reliable figure.
Currently, about 4 billion videos are watched per day (!), so allowing for four extra digits on the displayed "watched" count, that would add up to 16 GB of added bandwidth, were every one of those videos to significantly exceed the former 32-bit counter.
Just because YOU say humans are somehow supposed to be vegan does not make it "normal" either; humans don't have razor sharp teeth and claws, but we evolved the intelligence to develop simple weapons and tools to make killing for food and cooking it efficient enough for humanity to thrive.
Your argument is invalid.
The lander weighs only about one *gram* on the comet's surface.
It's as if a single-cylinder engine running on a tabletop in the only room in existence suddenly backfired and a whole fleet of semi trucks/lorries sprang into being in an instant, already pre-loaded with cargo, starting from that engine's intake manifold.
You know that you don't have to just add useless and uninteresting words to something that already had substance, right? At least borrow some quotes from Socrates' Dialogues to spice things up: There is admirable truth in that. That is not to be denied. That appears to be true. All this seems to flow necessarily out of our previous admissions. I think that what you say is entirely true. That, replied Cebes, is quite my notion. To that we are quite agreed. By all means. I entirely agree and go along with you in that. I quite understand you. I shall still say that you are the Daedalus who sets arguments in motion; not I, certainly, but you make them move or go round, for they would never have stirred, as far as I am concerned. If you're going to say _nothing_, at least be interesting about it, post anonymously, or risk looking more clueless / foolish. This is why the moderation system is in place, and mods typically don't listen to inanities like "Well said" when deciding on what to spend their points.
1. I'm too busy to sit around thinking up additional words to throw in so I can score "mod" points
2. The people I like on Slashdot are too busy to read a bunch of additional words I only threw in so I can score "mod" points
3. It's not in my nature to waste words, or to waste time
