Scaling LLMs with Golang: How we serve millions of LLM requests (assembled.com)
While the LLM ecosystem is overwhelmingly Python-first, we've found Go to be exceptionally well-suited for production deployments. Our Go-based infrastructure handles millions of monthly LLM requests with minimal performance tuning. Beyond Go's well-documented advantages (see Rob Pike’s excellent distillation of Go's benefits), three capabilities have proven particularly valuable for LLM workloads: static type checking for handling model outputs, goroutines for managing concurrent API calls, and interfaces for building composable response pipelines.

CPU Throttling for containerized Go applications explained (kanishk.io)
It’s been a long time since I wrote something here. Past few years I’ve been busy at work which is where most of my writing is done these days. This particular entry comes as an offshoot of a production disaster I saw and then took the opportunity to dive deep and learn more. What seemed like a convoluted problem at the outset, ended up being pretty fascinating in the end.

Don't defer Close() on writable files (2017) (joeshaw.org)
But this idiom is actually harmful for writable files because deferring a function call ignores its return value, and the `Close()` method can return errors. **For writable files, Go programmers should avoid the `defer` idiom or very infrequent, maddening bugs will occur.**
