HTTP/2 interop pains
At around 06:49 CEST on the morning of August 27 2014, Google deployed an HTTP/2 draft-14 implementation on their front-end servers that handle logins to Google accounts (and possibly others).

Pervasive Monitoring Is an Attack
That’s the title of RFC 7258 , also known as BCP 188 (where BCP stands for “Best Current Practice”); it represents Internet Engineering Task Force consensus on the fact that many powerful well-funded entities feel it is appropriate to monitor people’s use of the Net, without telling those people. The consensus is…

If You Can Read This, You're SNIing
