Concurrency must be part of your design vocabulary
Thread safety becomes simple only when it becomes habitual. Successful teams build concurrency into their design principles:
- Immutable data first
- Clear ownership of shared resources
- Avoid unnecessary shared state
- Prefer stateless services
- Use concurrency-safe primitives and patterns (locks, channels, actors, message queues)
- Review code with concurrency in mind
- Write deterministic, repeatable concurrency tests
This mindset does not guarantee that you will never hit race conditions, but it drastically reduces your exposure to them.

Detecting goroutine leaks with synctest/pprof
https://antonz.org/detecting-goroutine-leaks
A leak occurs when one or more goroutines are indefinitely blocked on synchronization primitives like channels, while other goroutines continue running and the program as a whole keeps functioning. We'll look at some examples shortly.

Dear Junior Coders: Stop Chasing Shiny Objects
Focus on mastering foundational programming concepts and timeless technologies rather than constantly learning new frameworks and tools. Core skills like SQL, HTTP, data structures, design patterns, and clean code principles have remained relevant for decades and provide better long-term value than chasing trends. Soft skills like collaboration, negotiation, and persuasion are equally important for career growth. Energy is finite, so concentrate efforts on going deep into fewer essential topics rather than spreading attention across many surface-level subjects
