The definitive guide with Factory analogy. Chrome's Multi-process architecture, typical C code examples (fork vs pthread), and deep dive into Green Threads (Goroutines).
Why does my server crash? OS's desperate struggle to manage limited memory. War against Fragmentation.
Two ways to escape a maze. Spread out wide (BFS) or dig deep (DFS)? Who finds the shortest path?
Fast by name. Partitioning around a Pivot. Why is it the standard library choice despite O(N²) worst case?
Establishing TCP connection is expensive. Reuse it for multiple requests.
"Should I always use threads?"
No. It depends on your priorities:
This is a pattern worth internalizing early: threading feels "faster" because it's lighter-weight, but one unhandled exception can bring down the entire application. When stability matters, processes with a supervisor pattern are the safer choice.
The right starting question is: "What happens when this fails?" That question determines whether to reach for processes, threads, or async. As engineers, we don't just write code—we manage trade-offs.
