Calculate libyear for a ruby project over time, for charting progress
# To generate the input file, I ran this:
#
# git log --merges --date-order --pretty="format:%h%d %aI" > first-commit-per-month.txt
#
# ... and then manually edited the file to have only the first commit per month. it'd
# be neat to geneate the list of target commits automatically.
#
# Note: this doesn't work with upstreamn libyears-bundler, because https://github.com/jaredbeck/libyear-bundler/issues/4
# However, my very hacky fork can do it: https://github.com/yob/libyear-bundler

Installing ruby 3.0 with rbenv/ruby-build with openssl 3

Bllergh. This is a real pain.

The openssl extension that ships with ruby 3.0 only compiles against openssl <= 1.1, but now openssl 3.0 is shipped in debian testing/unstable.

Ruby bug here: https://bugs.ruby-lang.org/issues/18658

Version >= 3.0 of the openssl rubygem does compile against openssl 3.0 though.

I use rbenv to manage ruby versions on my system, which uses ruby-build to manage installs.
