The goroutine leak detector will become generally available in Go 1.27. But did you know you can also use synctest (Go 1.25+) to catch goroutine leaks in tests? See how the two approaches compare: antonz.org/detecting-go...

This is a fun one: I just sent go.dev/cl/790740, which elides method wrappers for embedded types at offset zero, common for mixins/inherited data types. Doing this removes 60 _thousand_ method wrappers from tsgo's AST package, dropping the compilation of our main exe from 49s to 28s on my machine.

New rule dropped: anything above 11239 isn't the real Brooklyn.

Heads up, the page source on this form has a hard-coded list of "valid" Brooklyn zip codes: 11201-11239. Unfortunately there are more zip codes in Brooklyn (including mine), so it was impossible to enter with my address.

PSA: Green Tea GC in go1.26 is incredible 🚀 This is what we saw for two big Go services. We'll try to gather more data and share it soon.

My talk was accepted to GopherCon 2026 in Seattle! I'm back with more TypeScript+Go goodness, this time with another year's worth of experience under our belt. I had a blast at last year's conference, so here's to yet another one! www.gophercon.com/agenda/speak...

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.

csrc.nist.gov/projects/cry... CMVP has (finally!) Validated the Go Crytogrpahy Module for FIPS 140-3. Congrats and Thank you to @geomys.org and @filippo.abyssdomain.expert

@philpearl.bsky.social looked at #golang Swiss tables performance ⭐️ philpearl.github.io/post/swissing_a_table/

Here's an example. Average rent in LA for a 1 BR is $2500. A woman that lives in LA and earns an hourly wage, knows that if she can't work for a month, she needs to come up with $2500 or she will be homeless. After bills, she has only $200 left over. She saves almost all of it, and doesn't eat out.
