QUIC is now RFC 9000

Is it possible to compile quicly cli (referenced in the blog post) with musl instead of glibc. I had to add signal.h and it then compiled successfully but I got illegal instruction segfault when executing cli.

Ask HN: GitHub Download Hash Change?

Today, an issue was raised in one project I use, because their build system rejected an invalid sha256sum while downloading a dependency from a GitHub zip file.
The offending dependency is usrsctp (https://github.com/sctplab/usrsctp) at commit 9d6b99b:

People don't make these decisions for technical reasons only. Career wise it is a bad choice to spend your time working on pre-existing technologies. You don't become a distinguished engineer by iterating on existing technologies. You become one by being the creator of something new.
I think QUIC is great and does a good job solving the problems it was designed to solve. It is disingenuous to pretend these decisions were made only for technical reasons.
