when I asked people to explain how UDP works I got a lot of answers to the effect of "it's spray and pray"
but I'm having trouble thinking of examples of UDP-based protocols that actually work in a "spray and pray" way —
* DNS is "send 1 packet, retry if you don't get a reply”
* QUIC is a sophisticated system for streaming data over UDP
* I'd guess that video protocols correct for packet loss
* maybe statsd is a "spray and pray” system?
(please do not reply to this explaining how UDP works)
