16. The Event Loop
21. The Socket Server
23. Socket Server: On Connection
25. Socket Server: On Input
27. Just because you received data, does not mean it is all your data. Example: Windows telnet sends every keypress as it happens. Unix telnet waits until new line.
28. Messages could get broken up into multiple packets and arrive to the client in the wrong order. That is how the internet works. As they arrive the NIC may choose to send you what it can construct properly *now* and wait until later to send the rest.
29. Buffers!

47. • EventLoops • React\Socket\Server • connection, error • React\Socket\Connection • data, close, error • Ratchet\WsServer • Class implementing MessageComponentInterface • open, close, error, message
48. • Clients are basically the same as servers. • Servers need to know how to handle: connections, data inputs, disconnections. • Clients need to know how to handle: data inputs, disconnections. • Both need to be able to: send data to the other.
