Compiling V8 for alpine (link against musl)
#
# Building V8 for alpine is a real pain. We have to compile from source, because it has to be
# linked against musl, and we also have to recompile some of the build tools as the official
# build workflow tends to assume glibc by including vendored tools that link against it.
#
# The general strategy is this:
#
# 1. Build GN for alpine (this is a build dependency)
# 2. Use depot_tools to fetch the V8 source and dependencies (needs glibc)
# 3. Build V8 for alpine

Created April 5, 2017 19:58
Rake task to transfer Sidekiq jobs from one redis instance to another
# This task should be run inside an environment that is already configured to connect to the redis
# instance that we're transfering AWAY FROM.
#
# The task should be handed the URL of the redis instance that we're MOVING TO.
#
# To run it and pass in the destination Redis you'd do something like this:
# rake sidekiq:transfer[redis://...]
#
# As jobs are added to the destination Redis, they're deleted from the source Redis. This
# allows the task to be restarted cleanly if it fails in the middle due to a network error

Explaining the rationale behind using memoized helper methods for controller resources

Last year I started playing around with using memoized private helper methods in my controllers instead of the traditional instance variable assigns we see in RoR controllers. Here's an example:

class PostsController < ApplicationController
  helper_method :new_post, :post, :posts
  
  def new; end
  def show; end
  def edit; end
 def index; end
