M7 · Concurrency & the Memory Model

The "atomic" counter still loses counts

• 10:00 on the clock

  The clock is the server's. It starts when you press start, survives a reload, and answers after it are refused.

• No hints, no autocomplete

  The editor has completion, suggestions and hover docs off. You can run your code against the samples as often as you like.

• Debrief afterwards

  When it ends you get the answer, the reasoning, and where the curriculum teaches it.
