Aluminium is not found in a raw state in nature. It's an oxide ore that requires a fantastic amount of power to extract the metal. (i.e. break the O2 away so Mg has somewhere to go.) The sand used for glass, is pretty much right out of the dessert. (very little effort is put into splitting the Si from the O2)
Since when is kevlar transparent?
[is it] cheap enough to replace glass
Not even remotely. Glass is stupid-cheap to make -- and is made from the most abundant stuff on earth.
Adding someone to a circle doesn't magically give me permission to see their NON-PUBLIC posts. Plus, you can block anyone, and they won't see any of your posts. This is no different than facebook.
The entire problem was that it wasn't different from FB. G+ was just one in a long line of attempts to be facebook; and forcing everyone to "use" G+ certainly didn't make them any friends. So, the choice is Facebook By Facebook -- a system that's been around for a long time with relatively little change, or Facebook by Google -- who is well know for chucking things under the bus. Gee, surprise! Google's chucking G+ under the bus. Google simply cannot. leave. things. alone.
Windows (XP), Tivo, Apple (Mac OSX, iOS),
No, they aren't. Goggle is a bunch of f'ing children with the attention span of a 1yo in a room full of shinny things. They lack any vision, want every thing to look and function like Facebook (*cough*gmail*cough*), and constantly change shit that works and people ("the user") like because ooooo shinny.
Maybe. But if they're still there (and that's a big IF given the growing lameness of their products), they're chained in a cave deep under the Marketing Department tower.
With C and C++, the programmer has to keep up with it; thus they are constantly aware of memory usage. (well, those that aren't complete shits do.) In Java, the programmer has no say in it, so they don't think about it -- or for younger "programmers" (who may have never learned C/C++), don't know how.
You've obviously not work in the Real World(tm). Companies will continue using hardware as long as it works -- not broken, don't need new features/functions not possible through software update(s), or don't need additional capacity (based on space and/or power)
(Cell providers cycle through tech due to the last two.)
Unless you're AT&T (Uverse), whose entire plan for IPv6 is 6rd.
How the hell do you summarize two distant
We've allowed that bullshit in IPv4 for decades. The potential size that represents within IPv6 means it must be absolutely FORBIDDEN , from day one until the end of days.
RA, aka. ICMP router advertisement. Abandoned circa 1970 as a "bad idea". It was a colossally bad idea in the 90's, and f'ing suicidally bad in 2000+. Yeah, let's trust whoever the f*** on the cable claims to be a router and send it our traffic. Oh, to protect my network(s) from that brain damage, I have to buy new switches that support "RA Guard".
They didn't like DHCP. So "no f***ing DHCP in IPv6!" DHCPv6 is a bolt-on, staple-on, and bandaid addition to IPv6. It's a horribly incomplete shadow of DHCPv4, and still requires an RA tell you to use it.
SLAAC... originally 80bit prefix plus 48bit MAC. They ignored the fact that ethernet is not the only technology in the universe. That was later amended (breaking older stacks) to 64bits. The entire purpose for the vast over-simplification of address selection (for tiny embeded systems with limit RAM/ROM/CPU) became moot 7sec into the IPng committee's existance -- IPSec shoots all three in the head, repeatedly, with artillery. Everything supports privacy extensions these days, so the logic for random address generation and duplicate address detection is there -- and rather trivial. Yet it, and SLAAC, demands the prefix-length be 64. Just to put that silliness in perspective, that's a single LAN with every ethernet device ever created (that will ever be created) in it 65,536 times over.
This leads nicely into the blindness to history... a 64bit LAN is pure lunacy. Today and likely for several decades. But we "have an infinite amount of address space." Actually, NO, it is, in fact, quite finite: 128bits, to be exact. If we carve it up with the same pez-like abandon as the early IPv4 assignments, it will be even less "infinite". Sure, we can change the way we do things "with the next
If you're behind CGN, then by definition you aren't allowed to run "servers" -- i.e. services that require outside systems to initiate connections toward you. (www, smtp, bittorrent, etc.)
Bullshit. XP supports IPv6. (it's "experimental" and has no GUI, but it a) exists, and b) works.)
