Difference between exit(0) and exit(1) in Python
...it(0) to indicate success, and exit(1) or any other non-zero value (in the range 1..255) to indicate failure. Any value outside the range 0..255 is treated modulo 256 (the exit status is stored in an 8-bit value). Sometimes, that will be treated as signed (so you might see -128, -127, etc) but mor...

Is using Random and OrderBy a good shuffle algorithm?
..., if the algorithm isn't biased by the stableness of the OrderBy, then any range of values should give the same result.
The program then tests some values, in the range 1...4096. Looking at the result, it's quite clear that for low values (< 128), the algorithm is very biased (4-8%). With 3 val...

Is < faster than
...m -127 to 128 in a compact form in comparisons, but constants outside that range have to loaded using either a longer, slower encoding, or another instruction entirely. So a comparison like (a < -127) may not have a straightforward transformation.
