Recommended neat, fast #golang xxh3 implementation: New release, now with arm64 NEON: github.com/zeebo/xxh3

Released #golang compression v1.18.3 containing upstream CVE-2025-61728 fix: github.com/klauspost/co...

New #golang Reed-Solomon release. Contains new progressive field decoding and some significant speedups. Check it out: github.com/klauspost/re...

Vibe Coders will understand.

Compression library for #golang v1.18.2 released. If you are running v1.18.1 (specifically) please upgrade.

func ifElse[V any](cond bool, trueVal, falseVal V) V { if cond { return trueVal } return falseVal } At least it is more readable than ? :

Now even more #golang msgp codegen in v1.5.0. Now with generics. Generates code 1000x faster than your LLM! :D Give it a spin: github.com/tinylib/msgp...

Released v1.18.1 of the #golang compression library. You know what to do! Link as always github.com/klauspost/co...

Vibe coding is no joke. With good guidance and review it is extremely powerful.

TIL that you can compress .zip files with Zstandard (pkware.cachefly.net/webdocs/case... compression method 93), and that libzip and 7-Zip support that. libzip.org/news/release... github.com/ip7z/7zip/re...

Why does my custom domain handle switch to "⚠ Invalid Handle" every month or so? @support.bsky.team

Whoever did #golang "modernize" - thank you! pkg.go.dev/golang.org/x...

Excellent blog post about hooking up Go into Java for erasure coding: kohlschuetter.github.io/blog/posts/2...

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.

🙄 #golang

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

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

Realizing I needed to add a mutex to protect an RNG call, I almost ended up with this.... Need more coffee 🫘

Sent in in. Now I can only 🤞

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

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

I with just released about 2 years of work on improving compression with a fixed encoding LZ77 style compressor for #golang Our goal was to improve compression by combining and tweaking the best aspects of LZ4 and Snappy. Check it out: github.com/minio/minlz

New #golang compression package release. Mainly focused on non-assembly performance. Now uses "unsafe" - use "nounsafe" tag to disable. As always here: github.com/klauspost/co...

Wait? The #golang github.com/golang/snappy has been archived? Any background on this?

Time to upgrade all CI scripts ;)

Helped a friend a bit to make a #golang concurrent version of the excellent age stream format by @filippo.abyssdomain.expert Check it out if it sounds interesting: github.com/bifrosta/age...

Average shopping experience on @bandcamp.com

😜

The @fireflyzero.bsky.social ROM file format is a Zip archive compressed with Zstandard. For fun I wrote a small CLI in Go to extract these using the lovely compress module by @klauspost.bsky.social (Note that you could just as well use `firefly_cli import <file>`) gist.github.com/peterhellber...

Pretty fast, pretty random, endless, seekable #golang Reader: pkg.go.dev/github.com/m... (16KB internal block of random data, xor with 32B value based on offset ⊕ per instance value) Made for benchmarks, not crypto, it is trivially predictable. ~20GB/s with Go single core. ~60GB/s with amd64 asm.

My album of 2024: Vows by MATTE BLVCK Simply an all-killer album, that just keeps developing. Styles vary between tracks, but solid all the way the way through, with a modern touch and even some instrumentals. Check it out if you are a bit into dark synth: matteblackus.bandcamp.com/album/vows

Best 5 minute TLDR of CGO in #golang I can think of. Maybe a bit overstated, but an "approach with caution" is probably a good takeaway from a 5 minute video. youtu.be/8mU7KIF6l-k

Teaser for next year :)

How many % speed improvement is worth it for "unsafe" in #golang? Should build tags be opt-in or opt-out?

Is it just me, or can we drop "naming things" in favor of "timeouts" in "two hard things in computer science"?

Trying something new: Pop-up coliving/coworking. I will be in Bansko, Bulgaria in June next year. Join if you also want to try digital-nomad-lite. Driving from .dk - so DM if you want a lift from along the route. Link if you are interested: casabasilico.online/coliving-ban...

Double negative... Most intuitive example... I *guess* this means `if (s3:if-none-match == null) == false`

Love how javascript games are basically open source (ok, "source available" for the zealots). Let me just add some more coins.....

This issue feels like a #golang job interview.. So I made it one :D Here if you want a serious challenge (less allocs = better): go.dev/play/p/M-O6r...
