    Sometimes I wander into wonderful rabbit holes.This week's adventure, "What’s the fastest way to multiply two 32-bit numbers on an ARM Cortex-M0 CPU?"If you're thinking Karatsuba multiplication (https://en.wikipedia.org/wiki/Karatsuba_algorithm), you’re wrong.While Karatsuba offers a lower asymptotic complexity (around O(n^1.58)), it only pays off when used recursively on larger integers.On the Cortex-M0, Karatsuba runs much slower than the plain naïve multiply. It turns out, simplicity wins at this scale.Godbolt Source:https://godbolt.org/z/4rP7bnv6r#programming #math

    M(77232917) is officially the 50th Mersenne Prime.M(77232917) was discovered seven and half years ago. Now, thanks to the diligent efforts of many GIMPS volunteers, every smaller Mersenne number has been successfully double-checked. Thus, M(77232917) officially becomes the 50th Mersenne prime.This is a significant milestone for the GIMPS project. The next Mersenne milestone is not far away, please consider joining this important double-checking effort.https://www.mersenne.org/report_exponent/?exp_lo=77232917&full=1#math #maths
