njakobsen / live_database_dump.rb
Last active November 5, 2021 02:28
Live stream a database dump (or any other STDOUT) using Rails 4. Why would you want this? If you have a large database dump and want to avoid storing it in memory as Rails streams it. This allows pipe the dump directly into the http response instead of storing it as a file, sending it, and then deleting it. Let me know what you think! I've teste…
class DatabaseController < ApplicationController
def database_dump
database = Rails.configuration.database_configuration[Rails.env]["database"]
send_file_headers!(:type => 'application/octet-stream', :filename => "#{database}_#{Time.now.to_s(:human)}.backup")
pipe = IO.popen("pg_dump '#{database}' -F c")
stream = response.stream
while (line = pipe.gets)
stream.write line
sleep 0.0001 # HACK: Prevent server instance from sleeping forever if client disconnects during download

Guide to the Router Facelift

Ember Router Async Facelift

The Ember router is getting number of enhancements that will greatly enhance its power, reliability, predictability, and ability to handle asynchronous loading logic (so many abilities), particularly when used in conjunction with promises, though the API is friendly enough that a deep understanding of promises is not required for the simpler use cases.

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Add the current version and build number on your iOS app icon
#!/usr/bin/env ruby
# Requires ImageMagick: `brew install imagemagick`
# Requires version.sh from https://gist.github.com/osteslag/1089407
#
# Set RGM_STAMP_VERSION_ON_ICONS=1 in your build settings to enable/disable
# stamping on Debug/Relase configurations.
#
# Make base unstamped versions Icon.base.png, &c. in the source tree. The
# script will make stamped versions Icon.png, &c. It relies on Xcode to copy
