Difference between Debounce and Throttle

Debounce

Debounce a function when you want it to execute only once after a defined interval of time. If the event occurs multiple times within the interval, the interval is reset each time.
Example A user is typing into an input field and you want to execute a function, such as a call to the server, only when the user stops typing for a certain interval, such as 500ms.

Throttle

Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

1. Get an OAuth Token from GitHub

First you will need to get an OAuth Token from GitHub using your own username and "note"

Concurrency in Swift: One possible approach

• Author: Chris Lattner

Introduction

This document is published in the style of a "Swift evolution manifesto", outlining a long-term view of how to tackle a very large problem. It explores one possible approach to adding a first-class concurrency model to Swift, in an effort to catalyze positive discussion that leads us to a best-possible design. As such, it isn't an approved or finalized design
