512 is a power of two: 2 9 (2 to the 9th power) [1] and the cube of 8: 8 3. [2] It is the eleventh Leyland number. [3] It is also the third Dudeney number. [4] It is a self number in base 12. [5] It is a harshad number in decimal. It is the cube of the sum of its digits in base 10. [6] It is the number of directed graphs on 3 labeled nodes. [7]
This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.
The emitted code is specialized for certain data types and is faster than the standard Python code. Psyco does not support Python 2.7 or later. PyS60 was a Python 2 interpreter for Series 60 mobile phones released by Nokia in 2005.
Exponential-Golomb coding generalizes the gamma code to integers with a "flatter" power-law distribution, just as Golomb coding generalizes the unary code. It involves dividing the number by a positive divisor, commonly a power of 2, writing the gamma code for one more than the quotient, and writing out the remainder in an ordinary binary code.
512 bits: Security claims: Large hashsum size: Structure: Miyaguchi-Preneel: Rounds: 10: Best public cryptanalysis; In 2009, a rebound attack was announced that presents full collisions against 4.5 rounds of Whirlpool in 2 120 operations, semi-free-start collisions against 5.5 rounds in 2 120 time and semi-free-start near-collisions against 7.5 ...

In computing, half precision (sometimes called FP16 or float16) is a binary floating-point computer number format that occupies 16 bits (two bytes in modern computers) in computer memory. It is intended for storage of floating-point values in applications where higher precision is not essential, in particular image processing and neural networks .
The attack mounts a known-key distinguisher against 53 of 72 rounds in Threefish-256, and 57 of 72 rounds in Threefish-512. It also affects the Skein hash function. [ 2 ] This is a follow-up to the earlier attack published in February, which breaks 39 and 42 rounds respectively. [ 4 ]
