JT used Claude Code to port Fabrice Bellard’s RISC-V system emulator to Go (not Linux itself, which runs from a special image). He tells the story (and shares the code) behind how it came together and shares lots of advice (and some of the downsides) for using LLMs in porting projects.

A limited number of 'Early Gopher' tickets are also available for the event (_28 remain at the time of publication_) – see the footer of [the homepage](https://www.gophercon.com/) for those. GopherCon **IN BRIEF:** - Last week we featured Robert Griesemer's [proposal for bringing generic methods to Go](https://github.com/golang/go/issues/77273) and there's been a lot of discussion over the past week to catch up on. - Damien Neil has written a proposal for [adding in-memory implementations of `net.Listener`, `net.Conn`, and `net.PacketConn`](https://github.com/golang/go/issues/77362) to Go. Why? No port exhaustion or other potential 'flakiness' during testing and the ability to inject errors and other behavior. - Nolen Royalty discovered that ssh's keystroke timing obfuscation was [flooding his Wish-based game server with ~100 chaff packets per keypress.](https://eieio.games/blog/ssh-sends-100-packets-per-keystroke/) The fix was forking Go's `x/crypto/ssh` to stop advertising `ping@openssh.com` support. [Your Go Tests Probably Don't Need a Mocking Library](https://rednafi.com/go/mocking-libraries-bleh/) — Redowan explores the argument that many Go testing scenarios can be handled effectively without resorting to full-fledged mocking libraries. He outlines several alternative strategies for isolating code under test, thereby promoting simpler and more idiomatic Go. Redowan Delowar [Detecting Goroutine Leaks with `synctest/pprof` in Go 1.26](https://antonz.org/detecting-goroutine-leaks/) — Go 1.26 is adding a new experimental `goroutineleak` profile that reports leaked goroutines.
