How we spent two months debugging Cloud Run latency, built out our tracing along the way, and learned the fix was one line of YAML.

A bit over two years after starting to work on it... Go is officially FIPS 140-3 certified 💥 csrc.nist.gov/projects/cry... I am pretty confident Go is now one of the most—if not the most—seamless and complete FIPS 140-3 compliance solutions... with a single env var, out of the box.

Damn, that felt good.
Issue: crypto: obtain a FIPS 140-3 validation #69536

FiloSottile closed this as completed 1 minute ago

Just a little over 1 year and 7 months after opening it... I think we can close this issue 💥

The native, upstream Go cryptography packages are now officially FIPS 140-3 certified, for everyone in the community to use.

We will continue to validate new module versions every year and v1.26.0, frozen from Go 1.26, is already In Process.

We're updating the https://go.dev/doc/security/fips140 page, for all other inquiries I remind you of #69536 (comment).

I don't do plugs often, but if your company relies on work like this being done professionally, Geomys (geomys.org) is how it happens. You should help us get a contract. You don't need to have spending authority! Just DM me, do an intro, and we'll drive the process. We're pretty good at it.

TypeScript team: rewrites compiler in Go. Go community: what do you mean your new compiler takes more than a minute to compile? Unacceptable. Dishonorable even. We are so sorry for this sub par experience. Not how we do things around here. Two days later: WIP 5x speedup. HN: why pick Go anyway?

On my first day at Edera, a post was casually dropped into general chat saying 'Hey! We're going to be starting series A chats, will keep you updated!'. I thought I'd at least get a welcome drink before sitting on the rocket, but weee let's go 👩🏻‍🎤🚀 P.s. We're now on Reddit! reddit.com/r/edera

Go 1.24 with go:wasmexport was just released, and there's a great blog post by Cherry Mui on how to use it too. go.dev/blog/wasmexp.... This was one of the most asked for features of the Go Wasm stack, let me know what you plan to build with it!
