N probably won't become final anytime soon. All the manufacturers promise software upgrades of pre-N to standard-N, and that looks fairly impossible now (except for the companies which get lucky and have something close to their version ratified). If standard-N appears, they have to deliver on their promises, so it's best for everyone if that doesn't happen.
I reckon that in ten to twenty years time Iraq will freely elect yet another lunatic, and we'll be going back again to try and straighten out another mess. You heard it here first.
More likely a major nation will decide that the freely elected government isn't to their liking and stage a coup. That's how most aspiring democracies around the world end.
If you're an OEM, you can just remove whatever the distribution picked for their browser and replace it with Opera. Microsoft doesn't let you remove IE.
From a consumer perspective, that a Linux distribution comes with Firefox is not really any different than a Windows distribution coming with IE. In both cases, I can go and get and use the browser that I want to use.
There are two key differences. First, monopolies have to play by stricter rules than everyone else. Second, almost every Linux distribution comes with more than one browser, and an OEM is generally allowed to remove those and replace them with their favourite (or just ship without a browser). OEM's can't ship Windows without IE.
The 5GHz band has been basically forgotten by the mainstream. This is your chance. Equipment supporting 802.11a is a little bit more expensive and 5GHz doesn't work so well through walls, but other than that it's pure upsides.
This is America we're talking about. You'd clean up the immediate area, build a massive sculpture and fret about it for the next three decades while waging an ineffective War Against Radiation.
The dust is heavy and will likely fall to the ground. You aren't particularly screwed if you breathe in a bit of dust. The deaths from lung cancer will increase, but city air is full of things which cause lung cancer anyway. We don't evacuate them because of that.
The only weapons of mass destruction which actually deserve their name are real nuclear weapons. Possibly some weapons based on high explosives or fuel-air-bombs could be included too, but those are apparently not scary.
It's amazing how they can decide that "the right of the people to keep and bear Arms, shall not be infringed." does not mean what it says.
That amendment has needed changing forever. Almost everyone agrees it doesn't apply if the particular arms we're talking about are nuclear. In order to avoid the interpretation making nuclear weapons legal to keep at home, you're forced to play word games with the first half that you didn't quote. Once you start down that road, there's no telling where you end up.
Not that I believe that people should have a right to keep or bear arms, but then I'm not a US citizen and I don't live in the US.
Imagine a terror loony who has powdered a couple of ounces of plutonium and wrapped them around a single stick of dynamite and then lighting the fuse and tossing it off of a tall building. Imagine a contaminated, major city that must remain uninhabited for the next 100,000 years.
You are scaremongering. Plutonium isn't all that deadly. You'd clean the immediate area, and life would go on.
You need to transport a given amount of power. You pick a voltage. If you then pick AC, you lose more than if you picked DC. It's that easy.
And with AC you can convert current and voltage with a transformer with a very high Q.
The most efficient way to transform AC is to convert it to DC, use power electronics to switch the voltage up, and convert back to AC. Transformers are terribly inefficient. Sticking with DC saves the AC->DC and DC->AC losses.
That's why AC (Tesla) beat DC (Edison) at the turn of the century for power distribution.
Edison didn't get to play with semiconductors and power electronics. You may not have noticed, but there has been a couple of technological advances over the last century.
Also, direct current generates more heat than alternating current.
Are Linux distributions that include packaged python versions and apps going to permit both 2.x and 3.x python versions to co-exist so all the apps (including local additions) don't have to be ported on the same day?
Fedora is trying hard to avoid that, because it is so difficult to have two versions installed in parallel. All python modules will have to be available in two (or more) versions, which is a royal pain.
However, it is not clear that avoiding it will be possible, so a decision hasn't been made yet.
If every photon (or all EM radiation) were absorbed by the medium and then re-emitted, the very first entry into a medium would result in a complete scattering of the radiation in all directions.
Mirrors don't scatter the radiation in all directions.
Are these really SD cards and USB sticks, or wifi-enabled SD memory cards and USB mp3 players?
Yes, just plain SD cards and USB sticks.
SD cards usually go out of their way to act look a dumb lump of flash.
They implement wear levelling. Perhaps they try to do more aggressive wear levelling on the spots where the FAT is kept, I don't know. Either way it is highly annoying, but hopefully no new cards have the problem.
Your low slashdot ID should make you recall first HDs whose (little!) space was measured as power of 2.
Yes, the HDD sizes were wrongly labelled in the beginning. Yes, I'm sure that if the base-2 size had been smaller than the base-10 size, the manufacturers wouldn't have switched. That doesn't change the fact that what they are doing now is correct, and what they did before was incorrect.
But using base 10 instead of 2 on a system with binary logic is clearly impractical when counting memory.
Memory is the only thing that comes in powers of 2, and that is simply because address lines are expensive so you want to use all of them. Flash is generally accessed across a bus, so flash generally doesn't have a power of 2 size even if the individual chips usually do. I don't see the impracticality of using base 10 for memory.
They map to memory in case of swap.
Now you've lost it completely. They map to Star Wars movies if that's what happens to be stored on them. That doesn't mean we need to count their size in Star Wars movies.

As far as I can tell the original question was about indoor use.
Are UK WLAN spectrum regulations different from the rest of Europe?
No reason to go with A, as long as you make sure the N-equipment you buy actually supports 5GHz.

laugh. Yes, you're probably right.
My excuse is that I was ill.
Do they all contain photons?
Yes, but I'd recommend not using the word "contain".
Do other wavelengths have other "particles"?
No.

The only weapons of mass destruction which actually deserve their name are real nuclear weapons. Possibly some weapons based on high explosives or fuel-air-bombs could be included too, but those are apparently not scary.
The problem is usually that they decided to be extra careful about security and bought a PIX.
You'd think Cisco knew something about networking, but that knowledge certainly hasn't made it to the PIX/ASA department.

Line losses are based on current not voltage.
You need to transport a given amount of power. You pick a voltage. If you then pick AC, you lose more than if you picked DC. It's that easy.
And with AC you can convert current and voltage with a transformer with a very high Q.

In this house we obey the laws of thermodynamics.
Though there are more transmission losses with DC than with AC
There aren't, at the same voltage. In fact AC loses slightly more at a given voltage, up to a lot more for really long wires.
In nordic countries, salt is never used, since it would be ineffective most of the winter.
Denmark is a nordic country. It is also one of the countries which uses the most road salt per capita.
Mirrors don't absorb, they reflect. Reflection is different than absorption/re-emission.
How exactly do you believe reflection works?
Are Linux distributions that include packaged python versions and apps going to permit both 2.x and 3.x python versions to co-exist so all the apps (including local additions) don't have to be ported on the same day?

Wouldn't it then be powered purely by momentum and moving the other direction?
Theoretically yes, if you could get the light source strong enough and the friction low enough. In practice that would be hard.
If every photon (or all EM radiation) were absorbed by the medium and then re-emitted, the very first entry into a medium would result in a complete scattering of the radiation in all directions.

Kilo in kilobyte was picked because it is 1000, not merely to mean something large. Mega in megaphone is using mega in another sense of the word.
