#FuckCars as usual. Like Rage Against the Machine songs, social critiques should become less relevant not more relevant over time. This one from 1973 is far more relevant now than ever.

Cars are fundamentally reactionary, both in their purpose and in their utility to the dominant class.

"Exposing and Circumventing SNI-based QUIC Censorship of the Great Firewall of China"

They show a clever trick to improve the bang for your blocking buck. The GW filters based on the src port being greater than the dst port, the effect being they spend less CPU time on decrypting QUIC connections.

"The censor only processes a packet where UDP sport > dport, meaning they capture more than 90% of all QUIC client Initial packets, while looking up flow table for only 30% of all UDP packets."

They go on to show how to circumvent their findings.

Cool set of tools linked to today in a presentation in the #IETF #HAPPYWG session:

It allows you to characterize the Happy Eyeballs behavior of a client, such as to see how much of a delay in DNS resolution or TCP connection response triggers a failback from IPv6 to IPv4.

For 20 years Mozilla has developed one of, if not the most useful tools that web developers have.

Congratulations to the MDN team on such an awesome milestone. I'm happy that we've played some small part in its history and I'm excited to see how it continues to be central to every web developers job.
