We’re thrilled to have Vint Cerf at SharkFest’25 US! Vint is one of "the fathers of the Internet", who was an integral part in developing TCP/IP.

RFC1288, the #finger protocol, reminds you that:

> Any data transferred MUST be in ASCII format, with no parity

you don't need to use parity bits when sending data over #TCP

The final day of SharkFest’25 US pre-conference classes are well underway! @packetjay and Sake Blok are teaching classes about #TCP and #SSL/TLS troubleshooting.

Day 2 of #sf25us has begun with Chris Greer taking over teaching about TCP!
