webpack-dev-server with html-webpack-plugin
View README.md
$ npm install
$ ./node_modules/.bin/webpack-dev-server
$ open http://localhost:8080/webpack-dev-server/

Notes:

  • Note the trailing slash on the URL is significant. Without it webpack-dev-server shows a file listing page.
  • You need 1.0.11 or later of webpack-dev-middleware for this URL to work. With earlier versions you need to specify the full URL like this: http://localhost:8080/webpack-dev-server/index.html.
  • To get a non-autoreloading version of the page use http://localhost:8080/index.html.

Configure a Vagrant VM to piggyback off CNTLM running on the host

Zip a directory to memory in Ruby. The rubyzip library is pretty hard to use. I tried for ages to figure out how to zip a directory to a string in memory. So here's an example that zips the given directory to a Ruby StringIO object using rubyzip.
View gist:3385002
require 'zip/zip'
def zip(dir)
Zip::ZipOutputStream::write_buffer do |zos|
Dir["#{dir}/**/**"].each do |file|
path_for_file_in_zip = file.sub(/\A#{dir}\//, '')
if !File.directory?(file)
zip_entry = zos.put_next_entry(path_for_file_in_zip)
zos << IO.read(file)
end
