The tank`s deep orange colour is caused by ultraviolet light from the Sun striking the foam insulation over time.
The fresh foam on Atlantis` tank is however, light-coloured, some of it bright white and some off-white, indicating different repair techniques were used in separate areas.
So it's more like new foam on top of old foam. Apparently it happens very quickly, since every tank I've seen after STS-1/2 is orange.
The external tanks of the first two missions were painted white, which added an extra 600 pounds (273 kg) of weight to each ET. Subsequent missions have had unpainted tanks showing the natural orange-brown color of the spray-on foam insulation. The orange-brown color results from ultraviolet light from the sun striking the foam insulation over time.[1] The lighter, unpainted tanks have increased the payload capacity by almost the entire weight savings of 600 pounds.
I happen to *live* in Caracas, and the prevailing view is not one of the government spying on us (we have lower standards regarding privacy than the US or European countries), but many rather view this as an utterly useless expense. Besides the simple fact that a manageable number of balloons cannot possibly watch every alley and corner:
The undermanned, outgunned police will get to the scene only to take the statement from the victim, assuming he/she stays there that long after being mugged.
Any recording will be useless since cops don't dare raiding the slums where most badass burglars can be found.
To catch said crook when he hits again, they have to actually patrol their hunting grounds, which brings us back to square one, only $1.3M poorer (an average cop makes no more than $10K a year).
Then there's the certainty that the balloons will be shot at for the sheer fun of it, as a huge inflatable Santa deployed every year on the side of a building can attest to. The balloons are naturally partitioned to account for that, but given a finite number of compartments and a practically endless supply of bullets and shooters...
Your car battery, if it were made large enough to hold the same amount of energy as your 50-liter tank, would weigh about 17 tons (http://en.wikipedia.org/wiki/Energy_density):
50 l * 0.74 kg/l (gas) * 46.9 MJ/kg (gas) / 0.1 MJ/kg (Pb batt) = 17353 kg
For your laptop's battery, that figure improves by a factor somewhere around 6.
Startup current: 2.0 A on the +12V rail, plus 1.4 A @+5V
Power - Random R/W (avg): 13.6 W
(heat dissipation equals the power consumption, since there is no "output power")
Power consumption is mainly a function of the number of platters (5 in this case) which in turn determines head assembly inertia, and seek time (inversely). In any case, the inertia of one motor and hub plus five platters is surely less than four such assemblies with 2-3 platters each.
If it were simply an escalation of traditional technology, it *might* be a case of pushing-the-envelope-no-matter-what to achieve the oh-so-marketable 1TB, and the above would not apply. But nope.
As for noise: does anyone have an idea of how loud is 2.9-3.2 bels (typical) ?
...from when it was first presented. The heading in the magazine was far more sensational: "Are the Pyramids made of plastic?" and, besides the usual reasoning on the difficulties of transporting huge blocks of limestone along the Nile, and (IIRC) something about composition of at the quarry, it contained two bits of supporting evidence:
A microphotograph of what could only be a human hair (vellus) trapped *inside* the stone
An account by Pliny the Elder or some other ancient historian, of a "liquid that became dense (solid) when mixed with earth and heated" (it quoted the original Latin, something like "humoris sub terra [...] caloris densar[i]")
There's some more info here, about 15% down the page.
Davidovits referred to the concrete as "geopolymeric", which is surely what inspired the title to the editor. As far as I remember, his approach was still far from Von-Danikenesque and deserved serious consideration.
The "cellular" term originated in the US to differentiate a new access scheme from the older, non frequency-reusing radio telephone system, and caught on in several countries that imported the technology straight from the US, regardless of whether they ever had a radio telephone network. I for one prefer "mobile" as it describes function regardless of technology (the emergence of Wi-*, satellite, etc. would be non-issues).
The "phone" part of the name may be easier to challenge, since their functionality (Voice, [SM]MS, Data) is clearly a bit too much for the original "phone" concept. We just need something more digestible than "mobile communicator".
It will be activated automatically when installing an application update or extension, and users will be asked if they want to resume their previous session after a system crash.
Yes, and I also was thinking of the "reopen recently closed tabs" feature. It was my main use for the extension, since I'm always closing a tab by mistake or when I get impatient with what I'm reading. I'm glad to still have it - too bad I can't reopen windows as I did.
What about when I want to restart firefox for the fourth time today because I can't enter text into any text fields, or it's sucking up 1GB of memory?
I hadn't heard of such a bug with forms, but the memory leakage issue seemed to get a whole lot better somewhere along 1.5.0.x.
Well, I use a lot of invasive extensions, and I only lost Session Manager, which is unsurprising since Fx now includes a similar feature and they would probably step on each others' toes.

All in all, I agree that this is mostly an incremental upgrade, and it is somewhat faster, but I'm not sure it deserves the new major version. Several tiny UI bugs didn't get fixed.
Regarding the Geek-a-Cycle (and talk about unimaginative names):
Besides the obvious ergonomic nightmare (cf this) and the inconvenience of having to keep your (conveniently not shown) mouse from rolling off, I'd have serious trouble concentrating on the code at hand while pedaling away like a 180-lb hamster.
The other FA, well, I'm just too lazy to wait on YouTube feeds.
How about getting away from the computer from time to time to, say, get some sunlight on your hide?

With wired links you need contact pads, which spell trouble (dirt on the pads, dirt coming inside the package, tiny wires, etc).
You have to align the contacts for reading/writing. Even if this RF chip actually has to come within 1 mm from the antenna, the latter can have as large a surface as you want it to be.
iButton is a simple, rugged contact-based solution, but it's far from being cheap/small enough to put on every spare widget you sell.

So it's not only heavy-handed governments blocking WP. It can work backwards too. Oblig: in Soviet Qatar, Wikipedia blocks you!

This article, previously linked here does refer to HW costs and such (I was ready to denounce the post as a dupe).
