Polyglot Programming: TypeScript, Go, & Rust — A mind-bending tutorial journey about programming side-by-side in these three languages. This detailed video course shares how to get the most out of this multi-language approach, specifically by implementing a fully-unit tested CLI app and comparing the differences.

👀 wasmVision: A Way to Get Go-ing with Computer Vision — Fresh from the genius behind TinyGo and GoCV comes a high-performance computer vision processing engine you can customize and extend with WebAssembly (which you can generate with TinyGo – or Rust or C, if you're so inclined).

fmt.Sprintf vs String Concat — While code using fmt.Sprintf might look better-structured, simple string concatenation (+) proves to be somewhat faster. Why? Max digs into how fmt.Sprintf works under the hood.

Go Runtime Finalizer and Keep Alive — A look into Go’s runtime.SetFinalizer and runtime.KeepAlive APIs, two advanced features that have some interesting quirks and should be used cautiously. Finalizers are notoriously problematic (and may even be deprecated one day) while KeepAlive is easier to grok but will stop objects from being collected.

Creating a 'Brainrot' Language Server in Go — So-called ‘brainrot’ is a mishmash of next generation slang and memes. Follow along with this tutorial as the rizzler Jitesh creates a bussin' basic LSP server – no cap. Perhaps you can put the lessons learnt to more productive use? 😅

Machine Learning in Go with a Python Sidecar — While Python currently holds the ML crown when it comes to the diversity of projects and examples, Go is a great ‘glue’ language for working with ML and LLMs and tying things together, even if it involves talking to Python-based projects.

🕒 When 1.1: Natural Language Date/Time Parser — A very long standing, and useful, library. The idea is simple: given a string like “tonight at 11:10 pm” or “next wednesday at 4:20 a.m”, you get the date/time you expect. Has rules for English, Portuguese, Chinese, Russian, and Dutch out of the box.
