How do I precompile the Golang standard library? I'm trying to use Go compiler in a sandboxed environment, but compilation is very slow without a shared build cache directory, because the standard libraries referenced are compiled everytime. I wo...

I hope this helps, post an update if it does

“Life is too short to be a sysadmin, unless you really like that, or unless it's your job.”

I love that quote and going to frame it 🙇‍♂️

Who would have thought… lol

love it and 100% agree

The AI harness engineering hype is basically just people finding out that with leaner design, good encapsulation, simpler code, improved tools, working CI/CD and precise documentation one can be more effective at writing correct code.

We (@chris.blue and I) did an interview for the @antithesis.com Bug Bash podcast. It was an interesting discussion!

RSA test vector crowdsourcing instructions

Do you have an idle cluster? Can you spare a couple core-years?

Help me bruteforce some test vectors for RSA key generation edge cases!

Here are the instructions, it's just a matter of running a single self-contained cross-compilable Go binary that will report the results autonomously.

I have not paid a ton of attention to the uproar over RTO policies, bc we are all in on distributed teams and not going back.

My impression (via social media) has been that these were shadow layoffs.

Last month I asked an investor why they are doing RTO. He said: "Retention, mostly. And morale."

@metalmatze.de hi, we’ve met at kubecon and we talked about a project for benchmark trend visualization. If you found it again, I would love to see it. Thank you so much for the recommendation.

this worked for me, btw #golang

With more #golang conferences and meetups joining BlueSky, here is a starter pack with the ones I've seen so far!

type Cache[K, V any] struct { m sync.Map } // Get returns the result of new. // // If Get was called on k before and didn't return an error, Get will return the // same value it returned from the previous call. // // If Get is called concurrently on the same k value, new might get called // multiple times. All calls will return the same value or an error from new. // // The cache is evicted some time after k becomes unreachable. func (c *Cache[K, V]) Get(k *K, new func() (*V, error)) (*V, error) { p := weak.Make(k) if cached, ok := c.m.Load(p); ok { return cached.(*V), nil } v, err := new() if err != nil { return nil, err } if cached, loaded := c.m.LoadOrStore(p, v); loaded { // We lost the race, return the cached value and discard ours. return cached.(*V), nil } runtime.AddCleanup(k, c.evict, p) return v, nil } func (c *Cache[K, V]) evict(p weak.Pointer[K]) { c.m.Delete(p) }

weak.Pointer (Go 1.24+), runtime.AddCleanup (Go 1.24+), and sync.Map combine wonderfully into a 20-lines weak map. #golang

It associates values to keys, with automatic garbage collection once the key becomes unreachable. Using it to tie precomputed FIPS keys to PrivateKey values we can't modify.

Did you know you that you can run Go 1.24rc1 (or any other version) by just setting an environment variable?

$ GOTOOLCHAIN=go1.24rc1 go version
go: downloading go1.24rc1 (darwin/arm64)
go version go1.24rc1 darwin/arm64

This is supported since Go 1.21 (August 2023).

frood, an Alpine initramfs NAS My NAS is just one big initramfs containing a whole Alpine Linux system. It’s delightful. Here's why and how.

I wrote up how my NAS is now just a big initramfs based on Alpine Linux. words.filippo.io/frood/

It's been pretty great. Immutable, declarative, and very very simple. Just some files, a list of packages, and a short script.

The doc is in `go help mod edit`. How did I get there...? it's a long story.
