Ask Stephen Cook.
would the internet be possible without satellites?
Yes.
"The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies."
While satellites may be considered one of the technologies used to deliver 'the internet' today, it would still go on even if the space junk-acalypse were to come to pass.
buying my bf a usb b hub. when it says .2.0 ect. does that mean how fast the device works? or waaa?
Yes. While USB 2.0 is not the most recent version, it is still the most common and provides an effective throughput of 35 MB/s.
USB 3.0, released in 2008, offers a comparable throughput of 400 MB/s and is fully backwards compatible with the 2.0 standard.
Hubs are cheap, so go ahead and splurge on a 3.0 model (like this one from amazon http://amzn.to/1iRp5cl) and tell your 'bf' that he's lucky to have you.
Television is television, no matter what pipe brings it to the screen.
Ted Sarandos, Netflix’s chief content officer, as quoted in the New York Times last week. The company, which earned 14 Emmy nominations for its original content (including “Arrested Development," “House of Cards," “Orange is the New Black," and “Hemlock Grove"), seems to have a firm grasp on what television will be like in the future.
Reed Hastings, Netflix CEO, released a letter to the investors for Q2, and revealed:
Beyond series, we will be expanding our Originals initiative to include broadly appealing feature documentaries and stand-up comedy specials. Netflix has become a big destination for fans of these much loved and often under-distributed genres.
(via futurejournalismproject)
This is what the internet was designed to do for over twenty years and has been able to do for at least five. That someone is saying it today - not before - shouldn’t be honored. It should be a disappointment

can i play battlefield 3 on my laptop? i have a toshiba ultrabook u840/00q 14". i have the game running on my computer but it runs very slow and glitchy. i have the graphics settings turned to low
In general, I think it's difficult to get true gaming performance out of an entry-level laptop unless you're looking at Alienware or other gaming-specific rigs.
For Battlefield 3, I found these recommended requirements (posted below).
Recommended requirements:
OS: Windows 7 64-bit
Processor: Quad-core Intel or AMD CPU
RAM: 4GB
Graphics card: DirectX 11 Nvidia or AMD ATI card, Nvidia GeForce GTX 560 or ATI Radeon 6950.
Graphics card memory: 1 GB
Sound card: DirectX compatibl sound card
Hard drive: 15 GB for disc version or 10 GB for digital version
So, in looking at the specs posted for the Ultrabook U840, I'm guessing that your biggest problem is the lack of a quality graphics card. Notebookcheck.net states:
Our performance tests with the high clocked mainstream version of the HD Graphics 3000 in quad-core processors showed a performance level on par with the current entry level generations from NVIDIA (e.g. GeForce 310M) and AMD (HD 5450).
Does the docking station power supply damage the laptop battery if used directly on the laptop?
Typically they use the same power supply adapter (or at least the same configuration), so it shouldn't be an issue.
hey what are the four rules of a series circuit?
Thanks for the question. Five*Nerds looked into your Four rules, but found only three. Since we don't want to disappoint you, we've also included a link to this super-fly chapter on series circuits here. Perhaps start with Section 4-1: Definition and Characteristics of a Series Circuit.
Components in a series circuit share the same current. Itotal = I1 = I2 = . . . In
Total resistance in a series circuit is equal to the sum of the individual resistances, making it greater than any of the individual resistances. Rtotal = R1 + R2 + . . . Rn
Total voltage in a series circuit is equal to the sum of the individual voltage drops. Etotal = E1 + E2 + . . . En
hi there,i am busy migrating my SQL 2008 licence from one server to another accordingly. will it screw up my licence
Microsoft's licensing guide for SQL Server 2008 states:
For load balancing and dynamic allocation of resources within a server farm, you may want to move instances of SQL Server across servers. Effective September 1, 2008, Microsoft introduced changes to the license rules for moving instances of server software products across server in a server farm. For SQL Server, these rule changes apply to SQL Server 2008 Enterprise only.
When properly licensed, running instances of SQL Server 2008 Enterprise may be moved freely across servers within a server farm. (There is no 90 day minimum period before reassignment.)
For more information, refer to page 31 of the guide linked here.
Thanks for the question!
$3.19 & 20-Years Worth of iPhone Charges
I don't know if I'm more impressed with concept that one gallon of gas could provide 7,300 charges or that our automobiles can't seem to get consistently better than 25miles using the same quantity of fuel. Yeah, yeah,... I understand that moving a 3,000 hunk of steel is different that filling up a 1420mAh lithium-polymer battery.

It's true. According to Bill Colton, a VP at ExxonMobil, a single gallon of gas has enough energy to charge an iPhone once a day for 20 years. Of course, that's never going to happen but it's a point ExxonMobil uses to stress the fact that there is a lot of energy in gasoline.
That number is striking though. 20 years? And then you think about what gasoline is used for, fuel for our cars, and it all makes sense (kind of). Our cars which are three thousand some pounds and can hit upwards of 100 mph for miles upon miles rely on gas to work. If gas has enough energy to power that, it definitely has leftover resources to pump up our phones.
ExxonMobil goes on to say that gas is one of the lightest and most energy dense fuels there is, which I could not care less about because all I want now is somebody to figure out how to transform a gallon of gas into a chargeable resource for my iPhone.

We need a new "New Deal"
Dear President Obama,
I’m sincerely disappointed with this administration’s ability to stimulate an economic recovery.
While I am not a Democrat, when you were elected, I was pleased with America’s decision to elect you. The economy was showing signs of an economic break-down, and I thought “who better than a Democrat to stimulate the economy?”
Franklin D. Roosevelt got a lot of flak for the New Deal, but it was bold, and had lasting effects, which allowed America to be a world-leader in manufacturing for almost 50 years. Over the last 30, however, we have watched manufacturing go overseas. They say we can’t compete with the globe for cheap labor, but that’s not the point. While America rested on its laurels as best-in-class, the rest of the world invested in technology and education. Americans weren’t buying Japanese and German cars because they were cheaper, they were buying them because they were cheaper and reliable. We simply stopped competing because we thought we were too big to fail.
So where is your “New Deal?”
We are borrowing more money than we can ever expect to pay back. If I loan money to someone, I look at several factors: Have they repaid their debts in the past? Is the amount reasonable? Do I think they have the economic potential to pay me back? Thank goodness the Chinese don’t worry about all that.
So enough with the criticism, here is the constructive part…
1. Borrow as much money as we can from the Chinese, and anyone else who will lend it to us, while our credit is still good enough to get a decent rate, and we still have a Triple-A rating. It sounds counterintuitive, but it appears we are pretty much doing this already. The problem is that we are only borrowing enough to service our budget shortfalls, until the tax-base comes back. That is faulty logic, since you can’t tax companies which have moved overseas, and you can’t tax individuals who are jobless. You should only borrow money to make money—not to bridge a deficit which you don’t see going away.
2. Start a “New Deal.” Begin with repairs of the infrastructure which was built in Franklin’s era, much of which has been unmaintained since then. Dams, highways, bridges. This will get many blue-collar Americans back to work quickly, and will provide a small stimulus to the economy anywhere where infrastructure exists. The additional benefit is that if you are re-elected, you won’t have to bear the burden of your own Katrina-type disaster in Sacramento, or any other city which might be flooded if another levy should fail. If you run out of repairs, consider some upgrades or new construction—remember, we are borrowing the money, we might as well spend it all.
3. Build high-speed rail between major cities. This is a green solution, which should appeal to your base, but more importantly, it will give companies competitive advantage if they can ship materials and goods cheaply and quickly. The interstate system was a great innovation, but that was 20th century solution to a 20th century problem. Think transportation infrastructure 2.0.
4. Build next generation internet infrastructure with fiber optics to all high-density areas, and high-speed copper to all rural areas. “No child left behind” doesn’t work if children don’t have access to cheap high-speed internet. We can’t be leaders in technology and information if we don’t have access to it.
5. This last one is radical, so bear with me, and don’t judge until you are all the way through. Appropriate land in the Midwest, and build massive solar and wind farms. Think of projects that dwarf the Abengoa Solar project in Arizona. I know you are familiar with the project, since you committed $1.5 billion to it. Upgrade and centralize the electrical grid to handle all this new cheap clean power. Tax Americans for the generation of very cheap renewable energy from these sources, and provide it back to us free of charge, as a benefit for our tax dollars. Most Americans would gladly pay a few extra bucks in taxes, if we didn’t get an electrical bill every month. By consolidating the electrical grid, it should be very efficient, especially since solar and wind farms cost comparatively little to maintain. Clean coal and natural gas are great, but let’s face it; they will run out someday, even if we don’t agree when that is. As for existing power companies, let them feed the grid, and pay them a fair rate, as calculated by the tax dollars collected, and the percentage of power they create. Don’t approve any new projects if they don’t meet the criteria for the new Green Grid. Biggest benefit: Let anyone else in the world try to lure manufacturers away from a company that provides free energy. Added benefit: If Americans get their energy from their taxes, the prospect of owning an electric car is that much more attractive. The demand for electric vehicles will drive auto manufacturers to innovate, and create more value if the consumers demand the vehicles.
So there you have it, a New Deal for the 21st century. A deal guaranteed to get Americans back to work, and provide us the competitive advantages of cutting edge transportation, communication, and free electricity. I’d like to see any country in the world offer a better deal to manufacturers. We already know we have the best-trained people in the world, let’s give them a chance to get back to work. Heck, if everyone was working again, we might not even mind a nominal tax-increase to pay back all that money we decided to borrow to fund this thing.
Canada voted Tommy Douglas as “The Greatest Canadian.” He wasn’t a Prime Minister; he wasn’t a Nobel Prize winner; he didn’t invent insulin; reinvent the game of hockey; or invent the telephone. He was a Premier of a small province, who spear-headed the effort to implement Medicare. Implementing Medicare in the USA won’t make you the "Greatest American." Heck, from where I sit, it sounds like most people don’t even understand or want it. But I bet if you were the president who pulled America from the brink of slipping into third-world status with a Double-A credit rating; and brought back economic prosperity (for at least another 50 years until we forget to innovate again), you might have a shot.
Sincerely,
RSquare (R.B. Read)
Five Nerds hasn't made much of a secret out of our misunderstanding of AOL, and more importantly, why anyone still needs AOL.
It appears that AOL editors, Topolsky and Patel concur.
