How Go makes TypeScript's compiler 10x faster

Together with

📺 If you're more interested in the technicalities of the TypeScript porting project itself, Microsoft's Jake Bailey went deep in ▶️ this talk at GopherCon 2025.

Proposal: go run -c 'code here' — Some languages (like Python or Ruby) let you run once-off arbitrary bits of code as a one-liner from the terminal. Could Go do the same? Ian Lance Taylor, Rob Pike, and others weighed in on the idea in this golang-nuts thread.

Dan Kegel et al.

IN BRIEF:

• Go 1.27 Release Candidate 2 has been released.

• Go 1.26.5 and 1.25.12 have been released including two security fixes.

• The Go vulnerability database now marks golang.org/x/crypto/openpgp as unsafe, so govulncheck will start throwing warnings if you're using it.

• gopls 0.23.0 is the latest release of Go's official language server with fleshed out Go 1.27 support and an sqlrowserr analyzer that catches missing sql.Rows.Err() checks.

PROPOSAL UPDATES:

• maps.Same (formerly Identical) is coming to the standard library as a way to identify if two maps share the same underlying storage.

• x/net/http2's standalone Transport and Server types are now going to be deprecated (proposal accepted two days ago).

• sync/atomic may be gaining Max and Min operations (becoming a 'likely accept' two days ago).

• 🤖 The creator of htmx, a commonly used set of frontend tools (particularly in the Go world), shows off a practical example of using Claude to investigate a bug report and reflects on how AI fits in with being an 'older developer'.

• The Ruby community has created a great guide on how to start a Ruby meetup but the advice is general enough for it to be valuable to gophers too!

• Devographics, best known for their State of JavaScript surveys, are back with a more general State of Devs survey to take.

• 🤖 The creator of the Bun JavaScript runtime, recently acquired by Anthropic, wrote up the story of rewriting Bun in Rust, a controversial AI-powered porting effort. It took ~$165k of Fable usage (at API rates).

• A directory of how Postgres can replace other systems, whether that's cron, Kafka, Redis, Pinecone, MongoDB, or many others.

• It's old, but this guide to what every number shown in htop means is genuinely educational and fascinating in equal measure.
