Your Turn

  • Exercise: Nodes-2

    When I introduced the interval server, I said it sent a tick “about every 2 seconds.” But in the receive loop, it has an explicit timeout of 2,000 ms. Why did I say “about” when it looks as if the time should be pretty accurate?

  • Exercise: Nodes-3

    Alter the code so that successive ticks are sent to each registered client (so the first goes to the first client, the second to the next client, and so on). Once the last client receives a tick, the process starts back at the first. The solution should deal with new clients being added at any time.
