It's funny that "free"creditreport.com is upset that someone else is profiting off their name, when their name is designed to profit off someone else's. I don't think they existed before the US government mandated the credit agencies give you a free copy of your credit report every year (via annualcreditreport.com). "free"creditreport.com doesn't actually give you a credit report for free; you have to enroll in a reporting service to get it.
Let's say you are paying your mortgage, putting in your bank account information for a transfer. An attacker could inject additional HTML (Javascript, etc.) that sends your response to the attacker's server instead of the mortgage company's server, compromising your account info.
Or a simpler attack would be the bank's online banking login page: again, inject additional HTML to the bank's response, and now you submit your username/password to the attacker's server.
Peering is generally only considered "fair" if there is a similar flow of traffic in each direction (averaged over a good period of time). Peering agreements are written with certain traffic ratios defined, and going outside those ratios terminates the agreement or triggers a payment clause. It appears that in every case, Cogent traffic had dropped outside of the contract ratios, and so they were asked to pay for service like anyone else (as it was no longer an equitable peering), and instead they threw a public tantrum and blamed everybody else.
The details are never made public, so when it happens once, you don't really know who is telling the truth. When it happens over and over again with one provider, as with Cogent, a picture begins to form. Cogent is a "tier-1" wanna-be, but don't have the traffic to back it up. They've been caught lying before, so at this point, they have no credibility.
Actually, assuming you are talking about RSA, neither the private key nor the public key is the pair of primes or the product of the primes. The product of the primes is used with both the private and public keys, and the other part of the keys are two related exponents, one made public and one kept private.
Obviously, it passed syntax-checking, or the server wouldn't have loaded it. What you are looking for is semantic-checking, which is much more difficult. I expect that the generation scripts will be expanded to check for more things; that's generally what happens (you check for what you can think of, and expand the checking when someone thinks of a better way to break things).
Negative caching (in BIND anyway) tops out at 3 hours (it looks like.se has it set to 2 hours). The NS record TTL is 2 days, so only about 1/96 of servers regularly looking up.se entries would have made a request during the 30 minute window.
As for somebody being fired for making one relatively simple mistake: were you fired from McDonald's, Burger King, and Wendy's every time you dropped a fry on the floor?

At which point companies will stop developing hybrids. Companies are developing new hybrid technologies to make money; if Toyota were to spend millions (or billions) of dollars developing a better hybrid, but then Honda could spend $30,000 at the Toyota dealer and copy it, Toyota wouldn't waste their money developing it.
"Up" is not the problem in getting to space; it is the velocity that is the problem. A 747 can reach a top speed of 567 miles per hour, while orbital velocity is 17,500 miles per hour. So, even if you could make a 747 carry a fully-loaded shuttle (it can't), you'd still need to accelerate an additional 17,000 miles per hour (which would still require the solid rocket boosters and the external tank, which are the majority of the weight, which a 747 certainly couldn't carry).
The shuttle passes a speed of 567 miles per hour in the first 20-30 seconds of flight IIRC. They are already throtting back the engines by that point to reduce aerodynamic stress on the vehicle.
I find it hard to believe that there aren't still a lot of school libraries out there that still use card catalogues. But what do I know.
My sister teaches sixth grade, and last year she mentioned something about the card catalog. She got blank looks from her class, and finally one of the smartest, most studious kids raised her hand and asked what my sister was talking about. There was also an intern teacher in the room, and she vaguely remembered it. She did remember what happened to the cards though; some students took out library books and looked at the back of the check-out card (where they stamp the due date), and they were the old cards from the card catalog.
Some things you expect younger people not to remember; some things are a surprise.
The early Apollo flights to the Moon (Apollo 8, 10, 11, and IIRC 12) used a trajectory that would return them to the Earth with no additional engine firing; this was call the "free-return trajectory". Apollo 13 did _not_ use the free-return trajectory; they were on a path to orbit the Moon, and had to fire an engine (the lunar lander descent engine, since they were not sure about the state of the command module engine) to get back to a free-return trajectory.
Here in Alabama, the county coroner is an elected position. It requires no legal or medical experience, but it does have one important feature for cases like this: the coroner is the only county official that can legally arrest the sheriff.
The satellite TV providers (in the US anyway) provide you equipment for free (used to be yours, but now is considered a lease), and they do a credit check to see if you are liable to be dumping it on eBay or your local pawn shop.
They probably keep former customers in their databases because they often run specials that are available to new customers only (and by "new", they mean "never have had our service before"). They use name+SSN for identifying you because you can move, and they still don't want to consider you a "new" customer.
I'm not saying that these are good reasons for the way they do business, but they do have reasons (the decisions aren't just arbitrary).
GM is estimating it will need 10 kWh to get a full charge to drive 40 miles. If you only use it for your commute, that is an average of 21 days per month, or an additional 210 kWh usage each month, so it would almost certainly put you in the "high usage" range of my local utility rates. For over 1400 kWh/month, my rate is $0.08467/kWh. So that 10 kWh would cost you $0.8467. The price of a gallon of regular unleaded gasoline at the station I use is $2.399, so that 10 kWh would cost me the same as 0.353 gallons of gasoline. If I can drive 40 miles on that, the cost equivalence comes to 113 miles per "gallon", which is almost exactly half of the 230 MPH rating.
While an increase in gas prices would help that number, electricity prices will probably go up as well (bringing it back down).
In other words, 230 MPG is BS (at least from a cost perspective), even under optimal conditions.
As for power plants being more efficient, they are. However, the power distribution system has a lot of loss, and battery storage in the car has a big hit.
The TrueType font spec was developed by Apple to compete with Adobe. PostScript uses a different font system (PostScript Type 1 being the most common). Adobe didn't want to license just license the Type 1 format (or at least not for a reasonable fee), and it was also somewhat complex to implement (Type 1 fonts being mostly a subset of the PostScript language), so Apple developed TrueType (and then Microsoft signed on) to compete with Adobe. Adobe eventually released the Type 1 spec for free, but the damage was done.
That was probably the beginning of the downfall of Adobe from their high-point of technical excellence.
Because a nuclear reactor doesn't last forever. The steel and concrete (and the steel reinforcing structure inside the concrete) absorb a lot of neutrons over the years, and that weakens them. Now, you could replace it all, but that costs as much as (or more than) building a new reactor in a new location and shutting the old one down (especially when you consider the changes in technology over the life of the reactor).
Now, in some cases, it may be possible to build a new reactor on an existing site next to the old one, but that is touchy (lots of heavy construction == lots of shaking of the ground == sometimes cracked walls in nearby structures). That would save on upkeep for the shut-down reactor, as things like the security and technical staff can be shared between facilities.
Even fusion produces neutrons that will limit the life of the reactor (if someone could ever build a net-power-producing one).
Encryption is useless if you don't know who is at the other end. SSL and TLS are designed to stop man-in-the-middle attacks, and you cannot do that without trusted authentication.
This is nothing new; it sounds like the same thing the "download accelerators" have been doing for years. My ISP has been offering Propel for almost 5 years. The only difference is that now a browser vendor gets to collect stats about your web use.
Your numbers are a little off. I don't believe that fuel composed of 90% gasoline (with 10% replaced by any other fuel-worthy liquid) will only carry 85% of the energy. If that were the case, ethanol would be a 5% "hit" over an inert substance.
E85 has a higher effective octane, which could be used in higher-compression engines to actually improve efficiency. However, this would only work if the engine was E85-only (it could never run on pure gasoline). For that to be practical, E85 would have to be the normal fuel.
DEC Unix (aka DEC OSF/1 AXP, Compaq/HP Tru64 Unix) has done this since day one (and IIRC VMS did it before that). You have to enter License PAKs to get all kinds of functionality, including multi-user logins, development tools, cluster support, and AdvFS filesystem utilities.
How bad is your driving record (or everybody else's where you live)? I have a 2 year old car that costs me under $700/year, and that is good coverage with State Farm (not some no-name insurance company that doesn't actually back up the claim).
That doesn't go on forever though. If you buy a $15,000 car, it can't depreciate $3000/year for more than 5 years (and it doesn't do that anyway). My first new car was a $20,000 Honda CR-V. After 10 years, I sold it for $6000; that's an average of only $1400 per year. If you buy a new car every year, you may see a hit of $3000/year, but you don't have to buy a new car every year either.
They don't want to cure you, they want to treat you. A cure is a treatment that ends (because duh, you're cured). If you aren't cured, you have to keep going back to the doctor, getting nice expensive prescriptions, month after month, year after year.

Well, actually it was the fastest thing around, because it was the only thing around!

How is this different from what Apple does with OS X and Macs?

It wasn't "they should have know", it was "they were informed and ignored the warnings". Big difference.
