Go 1.27 expands experimental SIMD support with the archsimd package, giving developers zero-cost, type-safe access to low-level hardware intrinsics on amd64, arm64, and wasm.
Junyang Shao and David Chase explain the API design, how compiler optimizations replace architecture quirks, and share best practices for bounds checks and register allocation to get the most out of it.

les dejo uno de los mejores papers que leí sobre Harness Engineering.
explica muy bien:
1) qué es un harness
2) cómo están construidos los coding agents actuales
3) qué patrones se repiten entre Claude Code, Codex, Gemini CLI, etc.
4) hacia dónde está evolucionando la categoría
5) qué recomiendan si querés construir uno
todo parte de una definición simple:
Agent = Model + Harness
como complemento, también pueden leer el artículo que escribí sobre el tema.

¡La nueva generación de tests para web y apps móviles!
El framework se llama "e2e" y es de código abierto
✓ Mezcla IA con pruebas deterministas
✓ Compatible con OpenAI, Claude y cualquier AI
✓ La misma API para web, iOS y Android
→ github.com/tester-army/e2e
ALT Captura del repositorio de GitHub tester-army/e2e, un framework open source de testing E2E con IA para web y móvil. Se ve su banner, 3,9k estrellas, TypeScript y un ejemplo de test donde un agente actualiza un plan a Pro porque hasta los tests ya quieren hacer el trabajo por ti.

I ported the Omarchy screensaver engine (ttfx) from Rust to x86-64 assembler, and it's up to 17x faster!! One-shot translation by Opus 5.5. We keep drilling until the agentic drill bit hits bedrock! github.com/omacom/ttfx/pull/…

We caught up with Jonathan Amsterdam from the Go team at @GopherConLatam to talk about the new pkg.go.dev API, static analysis, and providing better insights on package quality for humans and agents. Check out what he had to say!

In this article, the @golang team gives a detailed explanation of how the new goroutine leak profiler works (and when it doesn’t) with multiple examples of bad patterns and how to fix them 👉 go.dev/blog/goroutine-leak-p…
GoLand may not fix your leaks, but the new profile is already available in the “Go Optimization” tool, so that you can find and analyze them without having to leave your IDE.

Ergonomic aspects were the major reason for why the Go team finally adopted generic methods – methods are inherently useful, even when they’re not called through interfaces. That’s what Robert Griesemer told us at the Go 1.27 release party.
Now Mark Freeman explains where the problem with generic interface methods lies in more detail on @golang blog 👇

When I first read about data races and the Go memory model years ago, it all felt kind of weird.
Why doesn't the snippet below work?
The Go memory model is quite long and advanced, so I decided to write a simpler explanation. It turns out this topic has some of the most interesting insights into how Go actually works.
