Add the following to application.rb:

$icallbacks = []
$icallbacks.define_singleton_method(:print) do
  puts sort_by { |(a, b)| -b }.map { |(a, b)| "#{b}\t\t#{a}" }.join("\n")
end

ActiveSupport::Notifications.subscribe("load_config_initializer.railties") do |event|
 $icallbacks << [event.payload[:initializer], event.duration]

PoC: GraphQL Ruby fragment caching

This example demonstrates how we can cache the response fragments in graphql-ruby.

Existing solutions only allow caching resolved values but not all the GraphQL machinery (validation, coercion, whatever).

Caching response parts (in case of Ruby, sub-Hashes) is much more efficient.

Benchmarks for GC Compactor

GC benchmarks for trunk vs gc-compact seem to be about the same:

$ make benchmark ITEM=gc
./revision.h unchanged
/Users/aaron/.rbenv/shims/ruby --disable=gems -rrubygems -I./benchmark/lib ./benchmark/benchmark-driver/exe/benchmark-driver \
	            --executables="compare-ruby::/Users/aaron/.rbenv/shims/ruby --disable=gems -I.ext/common --disable-gem" \
	            --executables="built-ruby::./miniruby -I./lib -I. -I.ext/common  -r./prelude --disable-gem" \

Faster Rails tests

Feedback loop speed in one of the biggest contributing factors to overall development time. The faster you get results, the faster you can move on to other things. A fast enough test suite is therefore critical to teams' success, and is worth investing some time at the beginning to save in the long run.

Below is a list of techniques for speeding up a Rails test suite. It is not comprehensive, but should definitely provide some quick wins. This list of techniques assumes you're using minitest, but most everything should translate over to rspec by simply replacing test/test_helper.rb with spec/spec_helper.rb.

• Lead with data
• bcrypt
• bootsnap
• Cache Time::utc calls

Description

This hooks will remind you to reference task in your commit, and remember your task ref for branch. Your commit messages will have style "[reference] message"

Usage

1. Create two files in your repo - e.g. [PROJECT_ROOT]/hooks/prepare-commit-msg.rb and [PROJECT_ROOT]/hooks/post-checkout.rb
2. Copy to first file (here will assume that this is a [PROJECT_ROOT]/hooks/prepare-commit-msg.rb):
