Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

Integralist

Lambda: standard

# Creating a lambda
l = lambda { |name| "Hi #{name}!" }

# Executing the lambda
l.call("foo") # => Hi foo!

A top-down look into Elixir (for Rubyists)

• Phoenix (as "Rails for Elixir")
  • Rails and Phoenix can get suspiciously similar
  • A code sample:
• controller.rb

Justin Searls presents, "Tenderlove: the DHH story of a boy named Gary Bernhardt"

Short abstract

Ruby has heroes. Demigods who show us how to write better code. Turns out: they're just ordinary developers! This is the story of how I discovered that by becoming Ruby-famous. In the process, I learned our hero culture is toxic.

Want to keep Ruby weird? Stop listening to us (right after my talk).
