You can convert between financial loss and loss of human life using implied cost of averting a fatality [1], which is about $10 million. [1] https://en.wikipedia.org/wiki/Value_of_life

Snowden is against government surveillance. It's hard to argue he can be used to justify SORM.

To be fair, by going after Snowden the US painted itself anti-free speech and pro-surveillance.

No capital letters, though. It is important to follow all security rules. Weakest link and such. If only his password was Maga2020!, it would be impossible to hack.

Let's see: * Letters - check * Numbers - check * Special symbols - check So the new, secure, password should be Maga2020!

You can make a small (relative to wavelength) loop antenna that has a sharp minimum, but it will be very inefficient. You want your directional antenna to have a sharp maximum (high gain) so that it can increase signal to noise ratio.

There is a big difference between spectrum analyzer hooked up directly to the input of the radio and an antenna in a van several blocks away, with reflections and noise thrown in.

A directional antenna has to be much larger than wavelength. Won't fit in a van if we're talking about HF (with wavelengths measured in tens of meters).

Initial amplifier does not let much energy flow backwards. More importantly, there's a lot of background noise on HF bands that will mask that weak signal.

Only if it's poorly designed (leaks local oscillator frequency back into antenna) and not shielded. Modern receivers use quadrature sampling detectors rather than traditional superheterodyne. In that setup any leakage would be on the s

I expected to see something along the lines of vans with directional antennas driving around Moscow listening for spurious emissions from local oscillators of superheterodyne receivers 465 kHz away from the number station frequency, as in O

There's a good reason why many laws in math and physics have two or three names. They are oftentimes discovered simultaneously by several people and it's not always possible to tell who was first.

The underlying assumption behind false positive rate is that tests are independent and identically distributed. If in practice this is not the case, then false positive rate becomes misleading.
21.
by pps43 6y ago
The tests themselves are fine, false positives are due to human error: "The high specificities (usually 100%) reported in PCR-based tests for SARS-CoV-2 infection do not represent the real-world use of these tests, where contamination

Snowden does not have the files. Did not have them when he arrived in Russia. That's why it took so long for the Russians to let him in. They could not believe he did not take any intelligence with him.

#2 means that there is no wistleblower protection in the intelligence community. What else could Snowden have done do to stop the crimes being committed?

I have opposite experience. My parents did not help me with homework beyond first or second grade. After that it was my responsibility, like cleaning my room. I was near the top of my class.
