Hash-Based Bisect Debugging in Compilers and Runtimes — If you’ve ever had to debug a large set of changes as part of an unfamiliar code base, this approach may feel like magic, so much so that Russ and others have created a CLI (bisect) to make the task easier. The explanation of using binary search, git bisect, and the bisect CLI here are very informative.

Go Range Iterators Demystified — In Go 1.22 (behind a flag) or 1.23 (currently in the release candidate stage), you can use the range keyword to iterate over custom collection types. Zach walks (iterates?) us through from the basics up to some more complex examples.

Building a Binary Search Tree with SIMD and Go's Assembler — When you want a little more performance than Go provides naturally, or access to underlying CPU features unavailable in Go, leaning on assembly language is one way to do it. Clément shows a practical example here.

▶  Give Your Go App 'Superpowers' with an Embedded NATS Server — NATS is a lightweight real-time client/server messaging system, but a cool feature of NATS is you can embed it directly into a Go app and take advantage of its features without relying on a separate server.
