Setup a mirror to use with $HOMEBREW_ARTIFACT_DOMAIN
View brew-mirror-artifacts.rb
# Homebrew has $HOMEBREW_ARTIFACT_DOMAIN which allows using a mirror for downloads:

# https://docs.brew.sh/Manpage#environment
#
# But no easy way to create such a mirror. This command which creates a mirror from
# all core formulae downloads. Pop it in /usr/local/Homebrew/Library/Homebrew/cmd/
# with a `chmod +x` and run `brew mirror-artifacts`.

View sidekiq-after_transaction.rb
# Weak ACID semantics for Sidekiq jobs
#
# Include this module in a Sidekiq::Worker class and it will defer enqueuing
# jobs for that worker within an open ActiveRecord transaction until it is
# committed. Rollbacks will prevent any jobs being enqueued at all.
#
# ActiveRecord keeps track of all records which are being utilized within a
# transaction so it can fulfil commit and rollback callbacks. We create a fake
# record that quacks the same way for the same hooks.

Simple Ruby thread safe rate limiter with Enumerator#rate_limited_to extension
View enumerator-rate_limiting.rb
require "thread"
# Simple thread safe rate limiter
#
# Supply a limit of operations, and an interval in seconds (defaults to 1
# second, so ops/sec).
#
# Call `#wait` on every operation which will return immediately or sleep until
# the rate limit is satified.
