Our Roadmap for QUIC and HTTP3 Support in NGINX
# Builds NGINX from the QUIC+HTTP/3 development branch
# - Based on the official NGINX docker image, including all modules built by default
# - OpenSSL replaced with LibreSSL to support QUIC's TLS requirements (statically linked)
#
# docker build --no-cache -t nginx:quic .
# docker run -d -p 443:443 -p 443:443/udp nginx:quic
#
# Note that a suitable configuration file and TLS certificates are required for testing!
# See <https://quic.nginx.org/readme.html> for more info

Some useful Git aliases that I use every day
#
# Working with branches
#
# Get the current branch name (not so useful in itself, but used in
# other aliases)
branch-name = "!git rev-parse --abbrev-ref HEAD"
# Push the current branch to the remote "origin", and set it to track
# the upstream branch
publish = "!git push -u origin $(git branch-name)"
