Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

post '/post' do
 response.body.inspect # This returns [] with the curl command given below
end


__END__

Curl command used is:

kgrz

require 'sinatra' # version: 1.4.0 and rack version: 1.4.1

post '/post' do
    request.body.each {|x| puts x.encoding} # each because the request is wrapped inside an object
                                            # that responds to each
end

__END__

`curl --data "Hello" http://localhost:9393/post` outputs "ASCII-8BIT"

If you want to use the net/ssh gem to kill the process:

    require 'net/ssh'

    Net::SSH.start('host', 'user', :password => "password") do |ssh|
      ssh.exec "ps -ax | grep ruby" do |ch, success|
        ch.on_data do |c, data|
          # Too lazy to write the entire code
          # The "data" object has the output that gets printed out to stdout
          # when the command `ps -ax | grep ruby` gets executed.
