Speaker: David Abrahams. (Tech lead for Swift standard library)
"Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.
OOP has been around since the 1970's. It's not actually new.
Classes are Awesome
When Swift was first announced, I was gratified to see that one of the (few) philosophies that it shared with Objective-C was that exceptions should not be used for control flow, only for highlighting fatal programming errors at development time.
So it came as a surprise to me when Swift 2 brought (What appeared to be) traditional exception handling to the language.
Similarly surprised were the functional Swift programmers, who had put their faith in the Haskell-style approach to error handling, where every function returns an enum (or monad, if you like) containing either a valid result or an error. This seemed like a natural fit for Swift, so why did Apple instead opt for a solution originally designed for clumsy imperative languages?
I'm going to cover three things in this post:
require 'net/http' | |
require 'json' | |
require 'uri' | |
@token = '' | |
def list_files | |
ts_to = (Time.now - 30 * 24 * 60 * 60).to_i # 30 days ago | |
params = { | |
token: @token, |
Here we use Homebrew to install rbenv:
brew update; and brew install rbenv ruby-build
~/.rbenv/shims
to your PATHrbenv install 2.2.2
and rbenv rehash
rbenv global 2.2.2
Now you can run gem install bundler
and bundle install
within your Ruby project.
