Evolving the Go Standard Library with math/rand/v2 — Generating random numbers takes much more than you might think. Go’s initial RNG has multiple flaws, but fixing it breaks repeatability requirements. So, the core team created a “version 2” package that keeps Go’s compatibility promise and sets forth principles for future such 'version 2' packages generally.

Secure Randomness in Go 1.22 — If you’re interested in how randomness has improved in Go recently, this is for you, as the authors dive more into the security requirements of some use cases, how Go was enabling insecure code, and how doing the ChaCha(Rand8) led to not only better, faster, more secure random number generation but also how “Go 1.22 makes your programs more secure without any code changes.”

Borgo: A New Language That Compiles to Go — People on Hacker News got very excited about this! Borgo’s authors aim to create a language “more expressive than Go but less complex than Rust.” The result is more type safety and it's certainly worth a look.

QUICK BITS:

• 📘 We have no affiliation with this, but saw Packt and Humble Bundle have paired up to do a Go programming book 'Humble Bundle' where you can get a lot of Go books for, well, you name the price.

• 🚀 It's interesting to see Go entering the heart of the Ruby ecosystem by powering Thruster, a new HTTP/2 server for Ruby on Rails apps.

Using Structs for Generic Argument Lists — The example compares running a new algorithm vs an old one, and comparing the results to ensure they have the same answer. Think of it as feature flags for testing refactorings, and how using structs + generics cleans the code up.

An Applied Introduction to EBPF with Go — We’ve linked to stories about eBPF a few times, and this article goes through the basics and two examples of using eBPF to measure resources, such as tracking packets.
