Note This is a little out of date. Rust has made some progress on some points, however many points still apply.

Philosophy

Progressive disclosure

Swift shares Rust's enthusiasm for zero-cost abstractions, but also emphasizes progressive disclosure. Progressive disclosure requires that language features should be added in a way that doesn't complicate the rest of the language. This means that Swift aims to be simple for simple tasks, and only as complex as needed for complex tasks.

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aacc --with-opus

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

An Operator's Look at RethinkDB

The Getting Started Experience

It's in Homebrew and just runs (relative to, say, HBase): awesome!
Having packages for popular Linux distros (I use Ubuntu personally and at work): awesome!
Serving the GPG key over HTTP: not so awesome :-/
apt-get -y install rethinkdb
It didn't start by default- great! I hate when services do this. I then looked at the start script to see how it knew (usually daemons use /etc/default/blah, but it has custom logic to see if there's anything in /etc/rethinkdb/instances.d, which is cool).
