However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.

In the United States a longer duty cycle is used, 50% for battery-powered buoys (20 seconds on, 20 seconds off) and 75% for on-shore beacons. Ramarks are wide-band beacons which transmit continuously on the radar bands without having to be triggered by an incoming radar signal.

Conception and funding. Musk first mentioned Falcon Heavy in a September 2005 news update, referring to a customer request from 18 months prior.
Insensitivity to sample size is a cognitive bias that occurs when people judge the probability of obtaining a sample statistic without respect to the sample size. For example, in one study, subjects assigned the same probability to the likelihood of obtaining a mean height of above six feet [183 cm] in samples of 10, 100, and 1,000 men.

In mathematics. 50 as the sum of two non-zero squares. Fifty is the smallest number that is the sum of two non-zero square numbers in two distinct ways: 50 = 1 2 + 7 2 = 5 2 + 5 2 (see image). [1] It is also the sum of three squares, 50 = 3 2 + 4 2 + 5 2, and the sum of four squares, 50 = 6 2 + 3 2 + 2 2 + 1 2. It is a Harshad number.
