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.

The missing tier for query compilers (scattered-thoughts.net)
Database query engines used to be able to assume that disk latency was so high that the overhead of interpreting the query plan didn't matter. Unfortunately these days a cheap nvme ssd can supply data much faster than a query interpreter can process it.

Why I Chose Common Lisp (djhaskin.com)
After ~7 years, I was done with Clojure. I was writing a some CLI apps, and I hated how long they took to start up. The community at large seemed not to care about this problem, except for the babashka folks. However, I spent long, hard hours banging my head against native-image and it just wasn't working out. It was incredibly painful, and at the end of it, I still didn't have standalone, fast-starting native executables.

MessagePack: It's like JSON, but fast and small. (msgpack.org)
MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it's faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves.

Understanding JVM Garbage Collector Performance (mill-build.org)
Garbage collectors are a core part of many programming languages. While they generally work well, on occasion when they go wrong they can fail in very unintuitive ways. This article will discuss the fundamental design of how garbage collectors work, and tie it to real benchmarks of how GCs perform on the Java Virtual Machine.

Lord of the Io_uring (2020) (unixism.net)
io_uring is a powerful new way to do asynchronous I/O programming under Linux. Doing away with various limitations of previous generation I/O subsystems, io_uring holds immense promise. For more details on what io_uring brings to the table, please see the chapter What is io_uring?

Multi-Path TCP: revolutionizing connectivity, one path at a time (cloudflare.com)
The Internet is designed to provide multiple paths between two endpoints. Attempts to exploit multi-path opportunities are almost as old as the Internet, culminating in RFCs documenting some of the challenges. Still, today, virtually all end-to-end communication uses only one available path at a time.
