Where does my computer get the time from?
Summary: In a lightning talk, Tony Finch explains how computers get time from Network Time Protocol (NTP) servers, which are organized in stratum levels. Stratum 1 NTP servers get time from reference clocks, often GPS receivers. GPS time comes from Schriever Space Force Base, which gets time from the US Naval Observatory. The USNO uses atomic clocks and International Earth Rotation Service data to maintain accurate time, with the International Bureau of Weights and Measures overseeing global standard UTC.

Why HTTP/3 is eating the world
Summary: HTTP/3, the latest version of the HyperText Transfer Protocol, has seen rapid adoption since its standardization by the Internet Engineering Task Force. The new protocol utilizes the QUIC protocol, which replaces TCP and offers improved security, privacy, and performance. HTTP/3's increased encryption makes it more resilient to sophisticated threats and offers better packet loss detection and recovery. The swift adoption of HTTP/3 is primarily due to its enhanced performance in loading web pages and streaming videos.
