The default slog API is loose enough that a careless line ships broken JSON to production. Pin it down with Attr constructors, LogAttrs, a context-borne logger, and sloglint.
Hoisting wire plumbing out of your Go handlers
Four of the five steps in every unary RPC handler are wire plumbing. Pin the service function signature and they fit in one generic adapter per transport.
Accepted proposal: UUID in the Go standard library
Notes on Go's newly accepted uuid proposal and the tradeoffs behind the API.

Switch, map of functions, and interface registry for dispatching in Go.
Observability as a design requirement
Is passing user ID through context an antipattern?
Why the middleware-to-handler boundary is a special case for context values.
What belongs in Go's context values?
A simple litmus test for when to use context values in Go.
Wrapping a gRPC client in Go

Mutate your locked state inside a closure
Why your mutex wrapper should accept a closure for mutation instead of a plain value, with examples from the standard library and Tailscale.
Your Go tests probably don't need a mocking library
Practical patterns for mocking in Go without external libraries. Learn to mock functions, methods, interfaces, HTTP calls, and time using only the standard library

Master Go test lifecycle with t.Cleanup(), subtests, and TestMain. Learn per-test, grouped, and package-wide setup patterns effectively.
Stop Guessing: MCP Elicitations Come To Visual Studio Code
VS Code now supports MCP elicitations from the 2025-06-18 spec, letting servers prompt users with structured native dialogs instead of guessing at parameters.
Please Don't Write Your Own MCP Authorization Code
Why most teams should let an API gateway handle the new MCP Protected Resource Metadata flow instead of hand-rolling OAuth in their own server code.
Confused Deputy Attacks In MCP, Solved With Azure APIM
Mitigating confused deputy attacks in remote MCP servers by enforcing per-client consent prompts and proxying Dynamic Client Registration through Azure APIM.
You probably don't need a DI framework
Dependency injection in Go doesn't need Dig or Wire. Learn why manual wiring beats reflection magic and how Go's design makes DI frameworks overkill.
Building Personal APIs
In which the author steals his data back from various tools and APIs and uses them to build his own panopticon-for-one
Deferred teardown closure in Go testing
Return teardown closures from test helpers to manage cleanup elegantly. Learn patterns for temp files, mock servers, and t.Cleanup() usage.
