A Go Security Cheatsheet: 8 Security Best Practices — Covers things like the use of modules, reflection, containers, and crypto packages.

How Buffer Pool Works: An Implementation in Go — Exploring how buffer pool management works in databases by building one.

Errors vs. Exceptions in Go and C++ in 2020 — Subtitled “Why and how exceptions are still better for performance, even in Go”, this is a return to a study done in 2018 and the conclusions are consistent.

Building DigitalOcean's API Gateway — The full story of how DigitalOcean built its own API gateway in Go.

Discovering and Exploring mmap using Go — mmap is a system call for mapping files into memory which can provide a neat abstraction for working with both. Here’s how to use it in Go along with when you shouldn’t.

How to Handle Missing Fields From a Struct? — Pick one: zero value or nil. (Don’t worry, Go will pick one if you don’t…)

<-time.After() Not Garbage Collected Before Expiry — Unlikely to affect you unless you have a lot of outstanding timers, but there are ways to mitigate the problem.

Anonymous Structs: What and Why? — An anonymous struct is a struct defined without a name meaning it can’t be referenced elsewhere. Pointless? No. There are some nice use cases like nested structs or marshalling JSON data, say, where Lane argues anonymous structs handily beat map[string]interface{}

How to Build Your Own Serverless Subscriber List with Go and AWS — How to build an email subscription sign up flow (complete with double opt in) using Lambda and DynamoDB. Can’t be bothered? Simple Subscribe is Victoria’s project with it all done for you ;-)

Automating Go Integration Tests with Docker — Integration tests are slow and often have external dependencies (like a database), so pushing them into Docker can help keep them isolated and maintainable. There are multiple approaches to this, and this is just one.

Introducing Pebble: A RocksDB Inspired Key-Value Store Written in Go — The folks at CockroachDB created Pebble as a RocksDB-compatible replacement for their storage engine. This post explains the why and the how of their process.

Go's Major Versioning 'Sucks' (From a Fanboy) — Go’s versioning policy beyond v1 is taking a bit of flak from some quarters of the community. To be fair, it’s a hard problem, and how we got here is understandable, and Lane concludes that “Go still has the best toolchain and ecosystem.”

Turn a Go REST API to GraphQL using Hasura Actions — How to convert an existing REST API to GraphQL by just defining types and configuring endpoints.

A Structured HTTP Fields Parser and Serializer for Go — “Structured Field Values for HTTP” is a forthcoming standard to define data types for HTTP headers and trailers (essentially headers that follow chunked HTTP responses). Learn about them and get a cool, Go-based parser as a bonus.

Lessons from Go: Keep Calm and Use the Byte Array — Byte arrays are ubiquitious in Go, despite being hidden being abstractions in other languages. And this is a good thing.

Deploying Serverless Go Functions with Netlify — It’s a bit convoluted, but the end process of having Go functions in your JAMstack might just be worth it.

How Code Generation Wrote Our API and CLI — Pace (Mat’s company) uses Oto to generate the API and clients for their offerings. Oto can be thought of as a non-binary, gRPC alternative aimed at Go use cases.
