have been informed that "tcp/ip transition day" was 40 years ago, on the 1st Jan 1983

if you're curious, the protocol used before was NCP, and it wasn't full duplex. that's why things like telnet et al are on odd numbered ports. the even numbers were used for the return path

anyway i guess that means it's the modern internet's 40th birthday, that, and a good way to make anyone born in 1983 feel old
