If you want to use curl or net-http/open-uri to access https resources, you will often (always?) get an error, because they don't have the large number of root certificates installed that web browsers have.

You can manually install the root certs, but first you have to get them from somewhere. This article gives a nice description of how to do that. The source of the cert files it points to is hosted by the curl project, who kindly provide it in the .pem format.

problem: Sadly, ironically, and comically, it's not possible to access that file via https! Luckily, the awesome curl project does provide us with the script that they use to produce the file, so we can do it securely ourselves. Here's how.

1. git clone https://github.com/bagder/curl.git
2. cd curl/lib
3. edit mk-ca-bundle.pl and change:

def get_movie_duration video_file
	
  # Run ffmpeg on the video, and do it silently
  ffmpeg_output = `/usr/local/bin/ffmpeg -i "#{video_file}" 2>&1`
	
  # Find the duration in the output, and force a return if it's found
  /duration: ([0-9]{2}:[0-9]{2}:[0-9]{2}.[0-9]{2})/i.match(ffmpeg_output) { |m| return m[1] }

  # If it didn't get a match, something is wrong. Log the error
  return "FFMPEG ERROR"

# First install tmux
brew install tmux

# For mouse support (for switching panes and windows)
# Only needed if you are using Terminal.app (iTerm has mouse support)
Install http://www.culater.net/software/SIMBL/SIMBL.php
Then install https://bitheap.org/mouseterm/

1. Create new container  
   a) docker run -i -t ubuntu /bin/bash
   b) docker run --name rails_dev_container -i -t ubuntu ubuntu /bin/bash
   The command line flags - i -t provide an interactive shell in the new container

2. Show running docker containers    ==> docker ps

3. Show list of current containers   ==> 
   a) docker ps -a   (Show all containers, both stopped and running)
   b) docker ps -n x (shows the last x containers, running or stopped, ex: docker ps -n 5)
