How to add syntax-highlighted code to PowerPoint slides (Mac OS)

1. pygmentize -f rtf FILE | pbcopy
2. Paste into TextEdit (in rich text mode: Format → Make Rich Text before pasting), and copy to clipboard again.
3. In PowerPoint, Edit → Paste Special… → Styled Text.

(Pasting RTF directly into PowerPoint doesn't work correctly, at least with PowerPoint 2008 — it extends colour spans longer than it should, and sometimes removes line breaks. Going via TextEdit seems to solve the problem.)

Routing in Ember

In Ember, the application's state manager handles routing. Let's take a look at a simple example:

App.stateManager = Ember.StateManager.create({
  start: Ember.State.extend({
    index: Ember.State.extend({
      route: "/",

We've seen lots of Ruby feature requests about converting an Enumerable to a Hash: to_h, map_hash, map_to, each_with_hash, etc. Let's look at one common, simple case of this.

Building a key/value mapping from a collection of keys is awkward. We commonly see Hash[*collection.map { |element| [element, calculate(element)] }] or collection.each_with_object({}) { |element, hash| hash[element] = calculate(element) }. Both are verbose. They require boilerplate code that's not relevant to the programmer's intent: to associate an enumerable of keys with calculated values.

Ruby has the idea of an association already: a key and value paired together. It's used by Array#assoc to look up a value from a list of pairs and by Hash#assoc to return a key/value pair. Building up a mapping of key/value pairs is associating keys with values.

So! Consider Enumerable#associate which builds a mapping by associating keys with values:

# Associate filenames with URLs. Before:
