Here you can find not theoretical, but practical patterns applicable to memory issues, concurrency, and overall, real bottlenecks you hit in production.
The guide has been recently updated with more depth (atomics, concurrency trade-offs, etc.), so worth revisiting even if you’ve seen it before.
Solid reference to keep bo…

Are Atomic Operations Faster and Better Than a Mutex? It Depends
From the author:
"Recently, while reviewing a pull request, a discussion arose about using sync/atomic versus sync.RWMutex.
It’s a question that comes up often when writing concurrent Go code, so I thought it would make a great post"

Advancing Go Garbage Collection with Green Tea (youtube). TL;DR:
Go 1.25 includes a new experimental garbage collector called Green Tea, available by setting GOEXPERIMENT=greenteagc at build time. Many workloads spend around 10% less time in the garbage collector, but some workloads see a reduction of up to 40%!

Embedding structs can quietly mask deeper-nested fields: a duplicate field name isn’t ambiguous unless it appears at the same ‘depth’, meaning your program may choose an unintended value.

Hello, folks! The upcoming Go 1.24 (supposed to be coming this month, Feb 2025) introduces a new go tool command, aiming to significantly improve the way project-specific tools are managed. This update eliminates the need for the tools.go workaround, reduces dependency bloat, and improves performance through caching. So,
- No more tools.go hacks
- Faster execution…

Testing code that involves time or concurrency can be a struggle. It often leads to hard-to-debug flakes in CI or long-running tests.
Go 1.24 is scheduled to be released in February and the release freeze has begun.
It’s set to include an experimental testing/synctest package designed to make testing code that involves time or concurre…

In Go, sync.Map offers a thread-safe alternative to traditional maps. While sync.Map can be highly effective in scenarios involving heavy concurrent access, it isn't always the best choice. In this article by VictoriaMetrics, you'll learn when to opt for sync.Map, how it differs from regular maps, and the performance trade-offs involved.

The purpose behind this package is to enable the canonicalization of comparable values. In other words, this package lets you deduplicate values so that they point to a single, canonical, unique copy, while efficiently managing the canonical copies under the hood. You might be familiar with this concept already, called “interning”.

A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
