Wrote up a practical introduction to SIMD using a real example from Ghostty. SIMD has a reputation for being complex, but the common case follows a simple, repeatable shape and shouldn’t be scary! Everyone should know at least this much. https://mitchellh.com/writing/everyone-should-know-simd

@mitchellh@hachyderm.io Seems to be inspired by PowerPC style SIMD? I always thought that "splat" was the perfect way to describe putting the same value in each lane. Fuck you, Sony, btw, for bricking my PS3 dev environment.
