Carbon footprint is based on net carbon emission. Growing food is carbon neutral but transporting it isn't. Transportation could be carbon neutral, and will have to be eventually (long term we'll simply run out of oil), and plants would still have lots of CO2.
A big mac will let you walk a lot more than 100 m. The calories in a big mac are sufficient to let me run about 7 km.
But yes, it's unlikely you'd eat that much more from walking. Generally people put the extra calories they don't use from walking (or light biking) into fat, and then use additional calories to move that extra fat around.
I don't know about the US but in Montreal the cyclists are awful. So are the pedestrians, of course, and the drivers are too, but that's mostly because they don't know how to drive (literally - it costs a fair amount of money just to have a drivers license so most people don't get them until they're in their 30s and can afford a car in the city... and who wants to take drivers ed when you're 30?).
Cyclists don't obey ANY rules. Any of them. It's extremely rare to see a cyclist stop at a red light, and they do things like ride the wrong way up one way streets then make left turns against the light. As a pedestrian crossing with the light (most pedestrians don' do that either), I've been very tempted to give riders crossing inches in front of me a little shove....
In other parts of the country cyclists (I am one) are quite good at obeying traffic rules. Not here.
That's not a driver, that's a converter. Like saving a Word document in PDF or RTF. If all printers spoke one or more of a half dozen protocols that would be no problem. The issue is that almost every printer has its own (usually multi megabyte) driver that must be used to talk to it.
You know neutrinos were a fudge factor to make the momentum balance in nuclear decays? And Gell-Mann kept saying quarks were just a mathematical convenience.
"Dark matter" is a placeholder, until we figure out exactly what it is and give it a latiny name. But we've been remarkably successful proposing the existence of new particles as the solution whenever "the math didn't add up." It's not a cop out at all. And this guy's solution is no different - he's proposing particles to do the dirty work too, it's just that his are virtual and require the existence of two gravitational charges, which, I suspect, will really screw up the rest of quantum mechanics and probably has some nasty clashes with relativity too.
I'm not sure why a simple particle that doesn't interact electromagnetically (we already know of three) should remind you so much of aether and an all pervasive sea of virtual particles popping in and out of existence, and incidentally being polarized by regular matter and exerting a gravitational influence (a universal dipole fluid if you will), doesn't.
The latter is pretty much precisely what aether was supposed to be.
What other protocols does the web run on? Or did you mean the Internet, which is not just the web, and uses all sorts of other protocols, some of which involve DNS lookups?
What? El Al is the Israeli national airline. They're widely regarded as having the most effective security (and always have) because they actually get attacked frequently, by serious professionals, not once in a blue moon by some committed whack jobs and occasionally by a rank amateur.
I guess you don't have a common name that's on the no fly list. US security LOVES me, and even when flying NEAR the US I've had to have my passport verified by calling Ottawa. I once got hand searched five times before boarding a plane, two of them within sight of each other.
They've actually eased off recently. My last flight through the US was just a routine trip through the metal detector. It was nice.
Which is exactly why they should be far more worried about checking that the pilot is actually the pilot than running him through the metal detector and confiscating his toothpaste.
It sounds like they're letting the pilots skip the metal detector and instead have their fingerprints checked. US airport security usually does stupid things. This one seems smart.

So was aether. All Maxwell's equations say is that electromagnetic waves propagate through vacuum at a particular speed. The rest was interpretation.

Apple has sold the odd million of them.
In my lab there are half a dozen, and they do very much replace paper. Reams of it. Filing cabinets full.
Monochrome is pretty easy to do with PDF. Duplex might be a bit trickier.
You sure can, if the third parties signed the copyright over to you (or whoever you bought it from).
Apple has made the odd contribution to CUPS (not to mention employing Michael Sweet) since 2007. So yes, "their CUPS... work" is perfectly accurate.
You've got quite the axe to grind hey?
CUPS was BSD licensed. Apple could have made a private fork and kept any of their contributions for themselves. They didn't.

Aether in spades.

God I hope so. Even Windows 95 didn't usually take more than an hour to install.

A Pentium II? To render text web pages and a few pictures (in a separate viewer)?
I hate to tell you, but we had the web with pictures and everything (yes and MP3s too) in the 90s with 386s and 486s.
Hey, with iOS 5 you won't have to do the USB cable thing anymore! Awesome hack!
Very impressive? He used Debian 1.3.1, which runs just fine on a 386 SX. He just installed it. Read the article.
I've installed Linux on a 386 SX too. Fifteen years ago.
Fell for that scam, did you?

The fingerprints might be a little harder to fake than the uniform and catalog case.

Or disable them. On most planes a paperweight to the head would do nicely.
If you don't trust the pilot, you're screwed.
Every time there's a story about cell service being cut off, someone brings up the doctor who can't get an emergency call.
If a hospital is set up so that lives depend critically on someone who isn't there answering a phone, go to another hospital.
