I've gone through three Roombas and won't buy any more. They take too much care and feeding -- even the ones that automatically recharge themselves. The reservoir is too small so you have to dump it too often, and after a year the battery won't hold a charge and you have to replace it -- for $100. And you periodically have to take the whole thing apart because the moving parts are all gummed up with cat hair. (You have to do this even more often if you actually have a cat.
There's already a lot of DC power transmission going on, especially outside the United States. You don't need superconductors for this; you just need high voltage and power electronics. With superconductors, you can do DC transmission at low voltage.
... but how do they know if a phone is being tethered?
Several possibilities:
User-agent sniffing.Remedy: Change the UA string on your laptop's browser to match the one on your phone. Downside: Be ready to surf crappy "mobile-enabled" sites on your laptop.
Deep packet inspection. P2P protocols etc are unlikely to be coming from your phone. Remedy: Use a VPN or an SSH tunnel.
Traffic volume. Statistically higher traffic volumes suggest (but do not prove) tethering. Remedy: Use fewer bits;)
Personally, I think that in the future "computer science" won't really be a separate field of endeavor - like walking or throwing a ball or writing a report, it'll just be something people do without spending too much time thinking about it.
Of course it will still be a separate field of endeavor. It's just misnamed. Remember what Dijkstra said:
"Computer science is no more about computers than astronomy is about telescopes."
That has a lot to do with man bashing. Intelligent women are permitted on prime time, just not intelligent while normal men, for purely political reasons.
What about House? Oh wait, he's an asshole. Never mind, you're right.
Google doesn't give a shit about some measly $56 million, 5-year contact with DOI. That's chickenfeed to them, and they know that contract will eventually go to Microsoft anyway. They're sending a message to other potential government customers that if they play fast and loose with the bidding rules, the big dog will crap on their house.
When it's private, it's not tyranny. In theory, your arrangement with your employer is voluntary on both sides. Either party can decide at any time to cancel the arrangement and you go your separate ways. The arrangement between you and your government, however, is much less voluntary. If your government puts you in jail, you can't just decide you don't like the food and leave.
This is why the founders wrote the BofR to apply to the federal government and not to private entities. (The BofR didn't even apply to state governments until much later.)
Of course in practice it might be very difficult to change your employer, but it's still easier than changing your government.
The side that the steering wheel is one doesn't really matter
Actually it does. For at least two reasons:
It's easier to judge whether your car will "miss" a car going the opposite direction when the other car passes on the driver's side.
On a two-lane road, it's easier to pass a slower-moving vehicle if the side you pass on is the driver's side. Otherwise, it's harder to tell if you're likely to be creamed in a head-on collision when you try to pass.
That's why in most cases when cars travel on the X side of the road, the driver's side of the car is !X. Obviously it's not impossible to drive with the driver's side on X, but it's probably statistically safer on !X.
Let's imagine some big, staid, boring corporation (like, say, GM) introduces a new product tomorrow. It's called the "Wheelfoot". It's a two-wheeled rolling platform and it carries you where you need to go quickly, without walking.
Obviously it's very much like the Segway.
But there are a few differences:
It doesn't have as good a user interface as the Segway. It's usable, but it certainly doesn't have that "man/machine mind-meld" thing going on that the Segway does. And it never will.
It's not as reliable as the Segway. It tends to just stop for no reason about once a day, leaving the user stranded. Sometimes you can reboot it and be on your way, but often you have to call a friend to pick you up and take the Wheelfoot in to the repair shop.
It can go twice as far on a charge as the Segway (when it works).
GM has licensed the hardware so you can buy Wheelfoots from multiple, competing vendors. But they all work basically the same way and run the GM user interface. This makes business customers very happy because they don't have to deal with single-vendor lock-in for the hardware, and even though only GM supplies the design and the software, GM is a nice, stable blue-chip company that no PHB will be fired for recommending.
Upgrade and add-on hardware is readily available from a variety of vendors.
The Wheelfoot runs a little faster than the Segway. Not much--just a little. But you can also overclock it and make it go twice as fast, which is impossible with the Segway.
The Wheelfoot costs 1/4 the price of the Segway.
Now, is the Wheelfoot still as irrelevant as the Segway? Which product--if either--ends up taking over the world?
(Note: I'm not suggesting above that the Mac cost 4 times as much as a Windows machine when Windows came out. Or ever. Don't take the analogy that literally.)
Slashdot Mirror
Heck, consumers can't even trust cars. #Volkswagen
Or Quora. I hate that site. They don't even have the option of not logging in the way EE did.
Just get a Dyson and use it. It works.
I also put fiber in my walls. Not just fiberglas but glass fiber. That was ... overkill. I use the CAT5; I don't use the fiber.
Yeah. 12-gauge wire rather than 14 for all power outlets has saved my ass numerous times. (Coupled with a 20-A breaker rather than 15, of course.)

The only location-aware app I want is one that tells me how to stay far away from Adobe and its crapps at all times.

...matter of fact it's all dark.

... but how do they know if a phone is being tethered?
Several possibilities:
Could simply be encoded in the network tracking. The endpoint of the TCP request is not the phone, it's the machine attached to the phone.
Wrong. It's NAT-mapped. The endpoint is always the phone.
Really? Windows improved that much? Maybe I should give it a try. Do you still have to type "win" at the prompt after booting up?
I believe you are referring to Charlie Sheen's operating system.

My personal philosophy is that the instant you hear the term "dumbing down" you can ignore the speaker. They don't have any valid points to make.
You, sir or madam, are destined for Internet fame. Behold the new Godwin.
Now f*ck off.

See? Seven of Nine's outfit was inspired by science after all.
Fail. Name one time when you ever saw Seven of Nine in a gravity-free environment.
