Do you really think the amount of oil used to transport vegetables (even multiple years-worth) is greater than that used to build those greenhouses? The great cost in shipping a bushel of tomatoes a few thousand miles isn't wrapped up in the oil, it's the logistics/storage/refrigeration/etc.
You seem to be overlooking a fairly crucial factor: Because the Model S has a halfway decent suspension and modern features such as traction control, the driver should be able to maneuver the car quickly enough to *avoid* a head-on collision. Why would you possibly think it's more important to optimize safety around an unlikely scenario like "head-on collision with a Humvee", than to avoid the accident altogether?
Also, I'm fairly certain tanks, semi-trucks and airplanes don't get to qualify for the "safest car ever" award, since, you know, they're not cars! Also, I think an airplane fares even worse than a typical passenger car in your contrived "head-on collision with a humvee" scenario.
I'm fairly certain that a roof that *doesn't* collapse in on the car's occupants during a rollover would be more of a "good thing for safety" than one which did.
Persona/BrowserID is a lot closer to OpenID than SAML or OAuth.
Doing SAML federation can be a bit of a nightmare, and AFAIK there's no "standard" way to do sort of on-demand federation between two entities (that is, if user using IdP A wants to visit service X, usually A and X generally need to already know about each other).
OAuth really isn't about *authentication*. It can be used for authn as sort of a side-effect, but it's really not its' intent.
As for OpenID (and OAuth and SAML, too), the big advantage of Persona/BrowserID is that your IdP doesn't actually know what sites you're visiting. If you take the additional step of using unique email addresses to sign in to each different site you visit, there's also no way for two different sites to know you're the same user (at least, based on your BrowserID "identity"... obviously there's other tricks they can employ).
When I first read about the Raspberry Pi I was excited because I thought they were going to recreate this boot to a BASIC interpreter-type of experience we used to have on Apple II's and TRS-80's and the like. That's the sort of experience that they claimed inspired the raspberry pi, and they claimed that sort of programming-based, learning-intensive experience was what they wanted the pi to be about.
So, I was very disappointed to see that by default, a raspberry pi really is "just a pc" that boots into your typical CLI, and the "getting started" instructions actually have the new user start up X right off the bat. Providing scratch and a python IDE are nice and all, but I feel like all the normal trappings of "just a pc" take focus away from the real point of the pi.
Agreed, but I think it's a hard issue to have a rational discussion about, without emotions outweighing reason. On the one hand, if society at large decides a genetic trait is undesirable, is it wrong to prevent people from screening for that trait? Heck, even if society decides a genetic trait is desirable, is it right to prevent people from screening out that trait for their own reasons? I know it's cliche or a platitude, but most of the time, determining right and wrong (to the extent that we could create effective rules or regulations) in these cases is really, really hard.
But with unlimited energy we could just build enormous refrigerators to cool things back down! Problem solved!
What are you talking about? The original submitter? Eran Hammer? The blog being linked to?
I honestly don't know what you're referring to -- could you explain for those of us who are out of the loop?
One potential objection to this is that you can't generally get most HD channels on a non-digital service tier. Probably for the very reason that they can charge you more for the same content by only providing on the digital tiers.
You know what? You're right! I should stop watching Top Gear and start driving million-dollar super cars myself! I don't know why this didn't occur to me earlier!
On the one hand, mineral claims have a long history and seem to have worked decently.
On the other hand, how do we prevent an unscrupulous company from doing just enough work to *claim* these asteroids, with no intention of actually following through and mining them. Then, acting as a rent-seeker when another company actually does try to mine the resources?
That our esteemed legislators say to themselves
"Well, that's that, then! I guess it's pointless to ban high-capacity magazines."
"This is insidious! Alongside a high-capacity magazine ban, we should also ban 3D printing! Clearly it's a technology that will only be used by TERRORISTS!"
I think something like the latter is more likely, and I'm not even one of
The plans & pricing page mentions that the $300 fee can be paid over the course of a year:
"$300 construction fee (one time or 12 monthly payments of $25) + taxes and fees". (from https://fiber.google.com/plans/residential/)
"My cousin is dyslexic and has terrible trouble reading and doing mathematics, but he's sitting pretty on a pile of cash and he's great at his job."
Okay, I'll take your anecdote to the next level -- since your cousin is apparently rich, but dyslexic, obviously schools don't need to teach kids how to read, either. Anecdotes are fun!
