I've been building www.thedsengine.com, a hands-on system design simulator where you don't just draw architectures - you run them and watch how they behave under load. The idea is simple: define a distributed system, send traffic through it, and observe live metrics as the system responds. What's live right now: A pre-built architecture (topology locked). Your job is to tune the knobs you're allowed to change until the system survives the testcase. Run the TCs, watch latency, thr...
