Nice idea by the way!

It's a lot like Binary Land, a game from the mid 80s: http://youtu.be/NLI415emLzQ?t=42s

Thanks a lot for posting this. I love that the lectures are broken up into smaller chunks, it makes the whole subject much easier to watch.

Didn't know about that one, thanks!

Nice little timesaver for such a common task, I'd just been doing the following (with vi editing on) but yours is much easier:

  esc-0-i-sudo

Great tips. !! is a nice timesaver when you've forgotten to prepend sudo to a command:

  $ /etc/init.d/rabbitmq-server restart
  Failed, need root access
  $ sudo !!
  Success

  $ pwd
  /some/really/long/path/goes/here
  $ cd /var/log/app
  Work in this directory for a while, then go to previous dir
  $ cd -
  $ pwd
  /some/really/long/path/goes/here

I went through the same process as you. I think it's okay not to have hard and fast rules for every acceptable situation to leave off parentheses, it's more a judgement call based on the readability of the statement.

`Require` and `console.log` are perfect examples where leaving off the parentheses helps with clarity, same with the call to `createServer`. In your example I'd even argue that you could do the same with `res.end` too.

I'm curious, would you prefer to write code like this over the explicit version?

  foo bar: 'baz', quux('onoz')

I like not having to specify parentheses, but only do so when it's immediately obvious to a reader of the code what the result of the statement will be.

Once you get rolling with Chef or Puppet, updating your servers feels great - no need to manually fiddle with shell scripts, or wonder "have I installed that package on all my machines?"

Getting to that point can take quite a bit of effort though. In my most recent attempt to install a Chef server on a fresh Ubuntu box, I quit the installation halfway through as I realised I wanted to change some of the values I'd entered into the setup script. After re-running the script I encountered errors, and all my attempts at scrubbing the aborted installation failed. It was easier to just start with a fresh image. I had these sorts of experiences all the time when using Chef and Puppet, they were really frustrating to setup.

I felt more comfortable writing my scripts in Chef because it didn't limit my ability to use Ruby, and the more relaxed approach to handling dependencies suited me. Puppet was easier to setup, had better documentation, and behaved more reliably for me. Neither seems like a clear winner, but I haven't spent a lot of time with them in about a year now, so things may have changed!

Thanks for posting that quote, the speech transcript is one of the most touching works I've ever read.
