A screen generator, also known as a screen painter, screen mapper, [1] or forms generator is a software package (or component thereof) which enables data entry screens to be generated declaratively, by "painting" them on the screen WYSIWYG-style, or through filling-in forms, rather than requiring writing of code to display them manually.
"spinner" will have an interactive spinning wheel and a fidget spinner [108] which can be toggled via the switch. For the spinning wheel, a dropdown menu can change the number of numbers on the wheel: from 2 to 20. [109] Whereas for the fidget spinner, users have to mimic a rotating motion [108] in order for the spinner to spin.
For these applications, truly random numbers are ideal, and very high quality pseudo-random numbers are necessary if truly random numbers, such as coming from a hardware random number generator, are unavailable. Truly random numbers are absolutely required to be assured of the theoretical security provided by the one-time pad — the only ...
As with the shrinking generator, the self-shrinking generator is vulnerable to timing attacks since the output rate varies depending on the state. In their paper, [ 1 ] Meier and Steffelbach prove that a LFSR-based self-shrinking generator with a connection polynomial of length L results in an output sequence period of at least 2 L/2 , and a ...
A counterpart to /dev/random is /dev/urandom ("unlimited" [8] /non-blocking random source [7]) which reuses the internal pool to produce more pseudo-random bits. This means that the call will not block, but the output may contain less entropy than the corresponding read from /dev/random .
The shrinking generator uses two linear-feedback shift registers. One, called the A sequence, generates output bits, while the other, called the S sequence, controls their output. Both A and S are clocked; if the S bit is 1, then the A bit is output; if the S bit is 0, the A bit is discarded, nothing is output, and the registers are clocked again.
A spinner or numeric updown is a graphical control element with which a user may adjust a value in an adjoining text box by either clicking on an up or down arrow, by pressing an arrow key down or moving mouse wheel, [1] causing the value in the text box to increase (if the up arrow is held down) or decrease (if the down arrow is held down). A ...
Random.org (stylized as RANDOM.ORG) is a website that produces random numbers based on atmospheric noise. [1] In addition to generating random numbers in a specified range and subject to a specified probability distribution, which is the most commonly done activity on the site, it has free tools to simulate events such as flipping coins, shuffling cards, and rolling dice.
