![]() XorShift128+ is a relatively weak random number generator. I’m hoping that no online casino relies on XorShift128+. He uses it to “hack the JavaScript lottery”. Douglas Goddard, a security expert, explains how one can “crack” this generator. The JavaScript engine inside the Google Chrome browser uses the XorShift128+ random number generator, created by Vigna. Also, you could possibly use this approach to win at online poker, if they were silly enough to use a simple random number generator. I like to call this process “cracking” because it is akin to getting access to the secret information you are not supposed to have as a user of this function. O’Neill, a professor at Harvey Mudd college, advocates against using random number generators that make such predictions trivially easy. If you know this state, you can predict all future outcomes of the random number generators. Such functions have hidden states, so that repeated calls to the function generate new numbers that appear random. In software, we generate random numbers by calling a function called a “random number generator”. ![]() ![]() NRK on Computing the UTF-8 size of a Latin 1 string quickly (AVX edition).Daniel Lemire on Computing the UTF-8 size of a Latin 1 string quickly (AVX edition).Daniel Lemire on Counting cycles and instructions on the Apple M1 processor.Mike Battaglia on Counting cycles and instructions on the Apple M1 processor.Move or copy your strings?
