What if Claude Code is “a guy in the Philippines”? 🤔🧐🤨
Once again, it turns out “fully autonomous” means “a guy in the Philippines.”
It Turns Out Waymos Are Being Controlled by Workers in the Philippines

Running Claude Code on a Linux box over SSH just unlocked a whole new world for me.
I’ve never managed to become an avid Vim user (too impatient, and lazy), but now I can code comfortably through SSH with Claude doing the heavy lifting.

With #FlightRecorder #Go introduced a powerful tool. As I'm involved in the #OTel Profiles signal, I have created an OTel receiver that transforms Go's FlightRecorder format into the OTel Profiles signal. Now you can analyze Go diagnostics in your own favorite backend/UI!

This past week I used my R&D week at @datadoghq.com to build a WASM transpiler that generates Go (ARM64) assembly code.
It's not publicly available - I want to rebuild it from scratch - but I can tell you that it works!

I'm looking for a PR review tool dedicated and native to macOS. I tried tools embedded to VS Code, but I didn't like the experience.
I want good UX and standalone app (so that I can track how much time I spent reviewing code).
Any suggestions?
