It All Starts With Templates

An Ember application starts with its main template. Put your header, footer, and any other decorative content in application.handlebars.

<header>
  <img src="masthead">
</header>

<footer>

Random idea

I'm a big fan of the Ops School idea. I've struggled for years about how to "train up" someone coming into this field. So much of our skill set is forged in the fire of outages and troubleshooting.

One of the things that is both good and bad about system administration and operations is that we tend to see patterns. It's good in that we immediately see things that stand out. The downside is we tend to superimpose that pattern recognition in inappropriate ways.

We had an interesting issue happen yesterday at the dayjob. I won't go into exactly what it was here but I had an idea based on some graphs I was looking at. It's part social experiment but it's also part problem solving skills.

Given the following image with no context, what do you think happened? What are some of the key indicator points that jump out and what pattern do they call to mind?

Sinatra like routes in Rails controllers

A proof of concept of having Sinatra like routes inside your controllers.

How to use

Since the router is gone, feel free to remove config/routes.rb. Then add the file below to lib/action_controller/inline_routes.rb inside your app.

$stack, $draws = [], {}

def method_missing *args
  return if args[0][/^to_/]
  $stack << args.map { |a| a or $stack.pop }
  $draws[$stack.pop(2)[0][0]] = args[1] if args[0] == :<
end

improving ruby benchmarking

stdlib's 'benchmark' is not good, at least, for every use case I've ever had for benchmarking.

So here's some hacking I did tonight.

db = Sequel.sqlite("/tmp/example.db")
