I'm a Jew, and I can say that you have absolutely no idea about what you are talking about. A convert is just as much of a Jew as someone who was born a Jew.
In many cases, encryption with multiple passes and/or algorithms can be attacked and solved as encryption with a single pass and/or algorithm.

Unless your opponent is encrypting white-noise for kicks, the result of a successful decryption is going to have statistical properties that are significantly different from those of an unsuccessful decryption. Of course, it's helpful if you have more information, such as the source material is ASCII text, or every file starts with a known magic number.
When you get back to the real world, let us know. You don't just wave a magic wand and completely redesign and reimplement a highly complex safety-critical system.
The solution for all these problems already exists. It's called the Serial Digital Interface. It's simple, cheap, and works over a single high-quality coax cable. It's used in professional video applications like television production and broadcasting. It doesn't do DRM, which I consider a feature. If you need to make a cable, just buy some Belden 1694A and a pair of 75-ohm BNC connectors.
As far as I can tell, there's little security on the system that handles ACH payments. If someone can get a payment request into the system, it's assumed to be valid by the bank that receives it. There is no PIN or image of a paper check that could be used to check the authenticity of the payment request.
That may be true, but a debit card only gives access to your draught account, not your savings. I wouldn't rely on that. My bank happily took funds out of my savings account to cover a deficiency in my checking account when presented with a very large check. The problem was caused by a data entry person at the bank who had shifted the decimal point one place to the right while entering the amount of the check, effectively multiplying it by ten. The bank's computer was programmed to take money from other accounts if there were insufficient funds in the checking account. It took a while to get the mess straightened out and to recover the money that the bank had mistakenly withdrawn from my accounts. Later, I did some research and what the bank had done was perfectly legal. The law gives them a lot of flexibility in how they deal with processing checks when there are insufficient funds in the checking account.
I wouldn't put it past them. Locally, I've read about a number of incidents where people have been carjacked, driven to the nearest ATM, and forced to withdraw cash from their account.
The sector size on a hard disk can be anything. All you have to do is modify the firmware and reformat the platters. There is nothing in the hardware design that strongly ties it to powers of two, unlike the address decoding logic and layout in most memory systems.
If the customer complains, just whip out your handy meter stick and beat them around the head and shoulders, while making rude comments in French about their parentage.
Their best estimate is that there will be 10-20 inches less rainfall in some of the poorest areas of the world, not to mention most of europe. What exactly do you think less rainfall is going to do? People are going to starve. Here's your gold medal for jumping to conclusions. Less rainfall does not necessarily mean that people are going to starve. Agricultural productivity depends on many factors. One of them is planting the appropriate crops for local conditions.
No. Refining is not an attractive business. The capital requirements are insane, the profits margins are cyclical and often low, nobody wants a refinery in their backyard, and any plan to build a new refinery is guaranteed to attract every lawyer within 500 miles. Lots of risk, little reward, why bother.
Dell's version of guaranteed on-site service is a fraud. Dell should not be asking consumers to disassemble their computers and remove or replace parts. What's next, GM handles a recall by mailing new parts to their vehicle owners, along with a video tape "Brake Jobs for Dummies"?
He's also a bit of a whacko. I'm sure that he's smart and knowledgeable, but he has a bad tendency of straying from the facts into the territory of the conspiracy nuts.
I've been doing some reading on the subject, and it does not seem to be as standardized as many people think. Here's an alternate set of rules, as supplied by an EE professor:
(1) all multiplication (in any order)
(2) all division, as they occur from left to right
(3) all addition and subtraction, as they occur from left to right His inquiry on the subject is worth reading. Many people treat implicit multiplication differently than explicit multiplication, and the ordering of multiplication and division varies.
You still had to understand operator precedence, so that you entered the numbers in the correct order. RPN calculators have the advantage of being more transparent to the user. Operator precedence is one of those things that often requires human interpretation, since there isn't a universally agreed-upon set of rules for humans and calculators/computers.
Many devices are susceptible to EMI. I recently saw this while testing a hand-held UHF two-way radio. When I pressed the push-to-talk button in high-power mode (7 W output), it killed a computer that was about 6 feet away from the radio. The computer just made a funny noise and turned itself off.
I've seen that on some computers that were originally designed for the Navy. It makes sense in a shipboard environment, where you don't want the main fire control computer going off-line for some minor problem in the middle of an enemy attack.

Get some EMT shears. They do a good job of cutting through plastic packaging. I bought several off eBay for a very reasonable price.

The only place where a binary base (2^30 etc) makes sense is when dealing with memory systems that use binary addresses.
All of which is irrelevant to the issue that I was addressing.

I can't help thinking of the judge reaching under his desk, and pulling a lever, dropping a 16 ton weight on the plaintiff and his lawyer.
