Exactly, that's not the question you're answering, but it is the question that is being asked in this context: what is the probability of rapid unplanned disassembly of SpaceX rockets.

But in this case the samples are small. If you flip a coin once and got tails, what is the probability of heads?

Ballistic missiles use stars mid-flight and inertial guidance system during the terminal phase. Cruise missiles follow terrain. Many of those systems were designed before GPS became operational, but even now relying on GPS is not particular

Let's say I take age and income of everyone in a city and train a regression model that predicts income from age. The model has slope and intercept that "encode" the information from all the people. It would not be possible t

Not just "direct" firearm sales, but content that "intends to sell firearms". This can mean any review, unboxing, etc. Also "instructions on manufacturing a firearm, ammunition" are expressly prohibited, even t

What is firearm exposure? Working next to a firearm? Working after being shot with a firearm? Any cell phone seems to do the former just fine, and I don't know of any radio, military or not, that can do the latter.

I was talking about the tactical radios discussed in the article (2km range). If you want the radio to let you watch video feed from a drone above, show a map with locations of other soldiers, or update Facebook status via satellite link, t

Well, the difference would be that I actually built radios, and at least some of them worked. It's really that simple, even without SDR. You already have a microcontroller that reads rotary encoder attached to the tuning knob and chang

APRS and packet radio existed since the '90s. They handle routing and multiple participants, and are rather resilient to interference. There is no encryption and no frequency hopping not because it's difficult to do, but because t

Modern radios are software-defined, or at least controlled by a microprocessor, so frequency hopping or even spread spectrum shouldn't be much of a problem.

Unlike self-driving car, radio is a solved problem. Marine and commercial transceivers from Icom and Yaesu are cheap and rugged. Ham radio operators sometimes even use transceivers build from kits, e.g. Elecraft. Adding encryption should b

The idea is interesting, but unfortunately it's still too hard to remember the rules and encrypt or decrypt by hand. One-time pad is much easier.

Ivan Pavlov, famous for his dog experiments, wrote about something he called "target reflex" (approximate translation, I could not find his 1916 book by that name in English). That's the desire to capture the flag, reach anot

H0 is no preference, H1 is preference for either clockwise or counterclockwise. In this test with N=1, there was not enough evidence to reject H0.

The exact shape depends on your cost function. If you want to stop as early as possible when a strong effect is present (at the cost of running the test longer when the effect is weak), you can make the area get wider.

That's easy, always round down and also carry max possible error (calculated by rounding up and subtracting the rounded down value). For example, 1/3 can be represented as 0.333 with error 0.001. Multiply it by 3 and get 0.999 wit

Not in the active shooter scenario. The standard approach now is to not even wait for SWAT, but to go in as soon as at least two officers are on the scene. The rationale is that active shooters usually stop killing people as soon as they ge

But in this example the banks are not really doing the classification. They're trying to figure whether it's more profitable to approve or to decline a credit application. That decision depends not only on probability of default (
