The worst downside (besides having to set up and manage the thing) is spam control. Gmail is excellent at this, and Postfix/Amavis/Spamassassin only catches a fraction of the incoming bad stuff. There are cloud services for spam filtering, but they seem expensive for a single user.
I prefer this visualisation;
I wanted to make a cool graphic to show the relative sizes of the IPv4 and IPv6 address spaces. You know, where I’d show the IPv6 address space as a big box and the IPv4 address space as a tiny one. The problem is that the IPv6 address space is so much larger than the IPv4 space that there is no way to show it to scale! To make this diagram to scale, imagine the IPv4 address space is the 1.6-inch square above. In that case, the IPv6 address space would be represented by a square the size of the solar system.
I think this is why logarithms were invented.
There's no bad way to spend $140 B (or more).
Blowing up children in Yemen would stand out as a bad way to spend that kind of money. vs. being put to productive use in the US economy.
As economic stimulus goes, I think I'd rather have bridges that don't fall down and railways that work than 1 Gbps to my home.
If the USG weren't trying to take defacto control of the majority of the Middle East, you could have both.
Quite so. Of course, end-of-war savings (peace dividends) rarely seem to materialize. Still, spending is good for the economy -- even if you only pay people to dig holes in the ground and fill them up. Of course it's still better if they fix bridges and highways and avoid shooting people.
Yes, but the Iraq war benefits the bankers, globalists, and components of the military-industrial-media complex. Nationwide gigabit fiber would chiefly benefit the citizenry and small businesses. So, the Legislators simply can't vote for such a thing!
There's no bad way to spend $140 B (or more). A lot goes into the pockets of workers who dig trenches and string fiber. (We really need those jobs.) Some goes to electronics manufacturers, but it all stimulates the economy -- and serves somebody's interests. The problem is if AT&T, Verizon, et. al. are locked out, especially if it's a government investment.
As economic stimulus goes, I think I'd rather have bridges that don't fall down and railways that work than 1 Gbps to my home. A mere 100 Mbs should keep me happy for the next 5 years, I'm thinking. I making do with 18 at the moment.
I've never heard of Occam's Razor. What is it? I'm imagining some kind of 7 legged, supersonic, invisible shoe.
It's an Olde English Cellphone.
Technically this is called aristocracy
Nope. Plutocracy. Aristocrats are aristocrats because their parents were aristocrats.
It's a British thing. Queen's English. What what.
Why exactly is a fluid necessary? I don't think there is a fluid.
Heat pipes work by evaporating a liquid at the hot end and condensing it at the cold end.. The fancy wicking stuff is to persuade the liquid to move back to the hot place to get evaporated again. See http://en.wikipedia.org/wiki/Heat_pipe .
There's a working fluid there somewhere, it must have come out, and it might be toxic. Or it might give you a high. The review is silent on this.
It's not a revolutionary invention, but it should be very helpful if they can cut the peak and the average power draw on the power grid by a substantial amount. There's an energy cost saving and also transmission grid saving. You don't need such a heavy connection between the train system to the general power grid.
