ECC usually covers specific paths or devices, but it doesn't give you an end-to-end integrity check. A similar situation happens with IP packets. You can disable packet checksums if you like to live dangerously. Then, all you need is a bit of noise or a hardware problem to silently corrupt data that flows over the network.
One of the problems that this is supposed to detect is blocks getting written to the wrong place or being read from the wrong place. I think it's one of those rare problems that stops being quite so rare when you have huge amounts of data stored on cheap hardware.
If this is the same scam that I've seen lately, have a little sympathy for the end user. The ad generates a nasty dialog box that can only be killed by forcing the browser to quit. The alternative is to "agree" to let them scan your PC. I'm paranoid enough about browser security bugs that there is no way in Hell that I would agree to that. The fact that their ad can create such a dialog box seems like a browser bug to me. Have you stopped beating your wife [Y/N]?
That made me think of the time I met one of the actors from "Planet of the Apes" at a special screening of the movie. He was in full ape makeup and costume. It looked absolutely real, even closeup and in person. What would the DMV say if I showed up looking like that, or some other hominid species?
Maps have many military applications, as does GPS location data. In some countries, it may be difficult or impossible for ordinary civilians to get accurate or complete maps. If you want to drop an artillery shell or ICBM warhead on a target, you need to know where the target is. A civilian (spy) with a GPS receiver can collect useful intelligence on the locations of sensitive installations. Some countries are very touchy about people taking unauthorized photographs of military installations and hardware. Satellite reconnaissance has changed things, but even on a satellite picture, sensitive information can be erased, doctored, or not released.
Where do people come up with these insane conspiracy theories? Do you really think the "vaccine lobby" is paying off doctors to immunize their patients? Get off my planet, right fucking now.
It was hardly perfect. It was expensive and took a small army of engineers and technicians to prepare and launch. If it was magically resurrected from its blueprints, we probably couldn't afford to operate it without a massive increase in NASA's budget.
I once heard someone define a supercomputer as a $10 million memory system with a CPU thrown in for free. One of the interesting CPU benchmarks is to see how much data it can move when the cache is blown out.
Years ago, a friend told me that copper theft was such a problem in Pakistan that his employer tired of having to regularly replace segments of their site's high speed data line and replaced it with a microwave relay system. The thieves would just pull one end of the cable down from the telephone pole and attach it to a truck, and then drive down the road, stripping the cable from the poles. Local law enforcement was useless.
ATSC is the standard for digital television broadcasting in the USA. It replaces the old analog system, NTSC. QAM is the standard used by the cable television industry in the USA for digital television and other data transport over coaxial cable.
Internet bandwidth is not a consumable commodity like electricity or oil. That isn't how the economics work. Network costs are driven by peak capacity, not the total amount of data transferred. Imagine if electricity could be generated at almost no cost at the existing power generation stations. You would still have to pay for the distribution system, which would be designed and sized to handle peak loads. Off-peak usage would have little impact on the cost of the system. An idle or lightly used data link is economically inefficient and wasteful. A rational pricing policy would encourage people to prioritize their traffic, and to make use of system capacity that would otherwise be wasted.
Agreed. Therefore, print should be a normal function that works like everything else, instead of a one-off magical statement.
Why? I can think of examples of both approaches. Putting some "magic" in the compiler allows you to do things that may be difficult or impossible to do in code written in the source language. This is often an issue with I/O statements. The C printf() function is an example of the problems of insisting that everything should be a normal function. In languages without support for variable length arguments lists, it's even uglier. You end up with "printString(), printInt(), printFloat(), printChar(), etc.", rather than "print <list-of-objects>".
Social Security is a "pay as you go" system, and always has been. Calling it a trust fund doesn't make it so. It's the Washington, D.C. version of Hollywood accounting.
It would be equally silly to ignore the fact that China, Russia and certain other countries have well-funded technical and military intelligence collection programs that have been running for many decades, and explicitly target the United States.
This was because they good guys stopped registering the dynamically generated domain names used by the botnet, allowing the bad guys to register some domain names and regain control.
Survival of the fittest does not mean survival of the smartest or survival of the strongest. What if Neanderthals are mentally and physically superior to Homo Sapiens? I can't wait to hear the NFL Players' Association bitching about unfair competition. These guys used to hunt mammoths with wooden spears. They don't need protective equipment and they will kick your ass.

Why not just take an axe to the office router? Not accepting mail with attachments would have the same effect in many businesses.

Isn't that similar to what produced the whales and dolphins? Their ancestors lived on the land and said "screw this, we're going back to the ocean".

I'm impressed, I'll have to check out the contest.

Actually, calculating is a very interesting form of mathematics, even if most people are not aware of it.
The reality is that it hasn't been isolated from the rest of the federal budget.

What company provides a man-rated LEO launch vehicle? Nobody.

I'm surprised that he wasn't charged with attempted murder. Did he get a plea bargain?

Owning a crowbar is not a crime. Using it to bash in the skull of your neighbor is a major felony. Likewise, it isn't illegal to have a pseudonym.

Reprogram the botnet to ddos and spam putin@kremvax.ru. See how they like a little of their own medicine.
