    The mighty world of BSDPlaying with again smolBSD, a fantastic metaOS system that I talked about a few weeks ago.I'm a newbie, a greenhorn, when it comes to meta-operating systems built on top of NetBSD.I am very eager to learn by doing, making mistakes in the process, correcting and feel the warmth of the BSD community, who is happy to correct, esp when I show that I read the docs after making the mistakesThe journey is fantastic, the learning process is fun. microVM's are amazing. I've registered 11ms boot times on this small machine with a few CPU cores (and 40GB RAM). The fun is endless#programming #technology #BSD #netBSD #metaOS #microVM #networking #qemu #host #bmake #curl #sshd #Linux https://smolbsd.org/

    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

    @evan I voted No but then realized some friends who moved from the Santa Cruz mountains to Raleigh, NC keep asking to move there. Does that count? 😆
