Sprockets Railtie Setup

This file at actionpack/lib/sprockets/railtie.rb defines the Sprockets::Railtie, defining another Railtie for Rails. This Railtie is responsible for detecting if the application at-hand is using CoffeeScript, and if so will set config.app_generators.javascript_engine on the application to be :coffee.

Next, this defines an initializer called sprockets.set_configs which sets up ActionController::Base to either use or not use sprockets depending on the configuration option config.assets.enabled.

Finally, this file defines an after_initialize hook for the application which is the real meat of this Railtie. If assets are disabled (with the config.assets.enabled config option set to false) then this after_initialize hook will do nothing.

If assets are enabled then, this initializer first makes a call to an asset_environment protected method near the bottom of this file which requires the sprockets gem, creates a new Sprockets::Environment object, and then co

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
