Un-archived github.com/klauspost/cr... repo after getting a bit more than 2x on IEEE CRC32 using AVX512. Will submit upstream to #golang, but if you want to test it out early check out the repo.

New #golang cpuid release. As always github.com/klauspost/cp...

IMO #golang is missing a clean way to send exact typed (and wrapped) errors across the wire between 2 similar binaries.

GOB would be ok, but registration isn't really feasible in big applications.

This kinda implies that it is all 32 bit systems?

Finally a #golang SIMD proposal I can get behind in overall terms! <3 github.com/golang/go/is...

proposal: simd: architecture-specific SIMD intrinsics under a GOEXPERIMENT · Issue #73787 · golang/go

Proposal Details SIMD is crucial for achieving high performance in many modern workloads. While Go currently allows access to SIMD via hand-written assembly, this approach has significant drawbacks...

Would a #golang MinLZ compressor level with a better "worst case" speed be useful? Overly dramatic example...

Now @klauspost.com - wish that my old profile link would redirect to my new one, though. @bsky.app

Yeah, that is what I tried to say. You definitely have to be aware of the difference to a() || b() || c() that terminates.

Not a solution for everything, but pretty good when you want everything to run unconditionally.

cmp.Or is so neat for error handling in #golang - just remember that *all* params are evaluated in order, and first error is returned.

// serialize serializes p as json.
func (p *someThing) serialize() ([]byte, error) {
var dst bytes.Buffer
comp := minlz.NewWriter(&dst)
err := cmp.Or(json.NewEncoder(comp).Encode(p), comp.Close())
return dst.Bytes(), err
}

Photek is a name I haven't heard for many years - in both meanings. Sounds good still!
