If the same watermark is added to each image, then you can estimate the watermark by averaging many images and subtract it to get original image back. If each image has a slightly different watermark, then simple averaging won't work.

NPR and PBS do sound just like government propaganda. Source: lived in USSR. There were no fake news in Pravda, yet calling it "far from government propaganda" would be a stretch. To some extent it's inevitable (he who pays t

Only about 3.5% of radioactive material from one reactor was released (there were four reactors). Also no large city happened to be close enough downwind. Some of the areas within 30 km exclusion zone still have levels of radiation too high

Ionizing radiation is bad for birds.

Solar, wind, hydro do not affect the entire planet. Even burning fossil fuels might be ok, if combined with CO2 sequestration. But this is irrelevant. I'm just saying that you do a comparison, you need to take into consideration risks,

Advertisers would still win, though. Instead of showing you ads for 10,000 subjects of which one interests you, they are now showing you ads for 2 subjects of which one interests you. Much better targeting. And if they want to link your pro

In many cases the programmer could not have made the decisions. For example, AlphaGo programmers could not win against top go professionals, but AlphaGo can. With a simple model like credit score it's easy to see which input affects wh

Based on that information, what is the probability of a nuclear power plant accident making a large city near it uninhabitable?

So if you played Russian roulette a couple of times and lived, it must be safe, right? Probability is events over trials, zero events in two trials means probability of dying is 0/2=0%.

The point is not how many people have died, but how bad the impact can be. Even if nobody dies, the need to evacuate a large city like New York or Tokyo because a nuclear power plant nearby underwent rapid unplanned deconstruction might eas

Comparison is incomplete without taking into consideration BDBA (beyond design basis accidents). Probability of an accident worse than Chernobyl is low, but not zero. Multiply it by economic loss from large densely populated area becoming u

Ballots are split in batches. Each ballot in a batch is counted twice, by two different people, and results are then compared. If the counts don't match, the batch is recounted.

Let's say there are 10,000 subjects and you are interested in 10. You click 100 links for the subjects you are interested in, and also 1,000 links picked at random. Now random subjects get somewhere between 0 and 2 clicks, way less tha

It does not take long to aggregate votes using paper ballots. I was counting paper ballots in a national election, and we were done before 11 PM the same day.

It's much easier to attack such a system than to defend it. Attacker only needs a short window of time, so can emit a lot of power. "Smart" gun can't do that, it has to work for years on small battery, so its signal must

Hunting is often done in the cold, wet environment. Dead batteries and electronics that doesn't work because of the condensation are pretty common. You really don't want to waste that one-in-a-season opportunity because some $0.02

Not really. There are better ways to deal with this problem, e.g., retention holsters and quick access pistol safes.

Negligent discharges happen because people break gun safety rules. In the entire history of USPSA there were only two fatal accidents. If you think it's a lot, compare to other sports. Besides, the device in question won't help in

The main threat is that the gun does not fire when it should. As soon as those "smart" guns are mandated (they can't win on the merits, as nobody is buying them), there will be $5 gun jammers all over eBay.

Hardware in human eyes is actually pretty bad. Modern cameras can record and process more information in higher resolution and dynamic range. The advantage is mainly in software. For example, I have a spot on my daily commute where I need t

It works the same way. 7720 in binary is 1111000101000. This is 13 bits. Square root is at most half as long, so first guess is 10000000 in binary, or 128. Square that, realize that it's too high, set the highest bit to 0 and next bit

Going to space is disaster management. By the time we find an asteroid that's going to cause another extinction event it will be too late to start space exploration.

If you perform the algorithm described in the article in base 2 rather than base 10, you'll get binary search. Instead of (10 A) do (2 A), etc. Each step is easier (no guessing and checking), but there are more steps because each step

The folk theorem of statistical computing [1] says that when you have computational problems, often there’s a problem with your model. So chances are that if your gradient vanishes with 32 bit floats, switching to 64 bit floats won't h

Your approach is equivalent to the one described in the article, the only difference is that they use base 10 instead of base 2.

Seiko and Orient for mechanical, Citizen for quartz. Many interesting models are sold only in Japan, but you can get them through SeiyaJapan or Higuchi-Inc.
