PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Simple Authentication in Rail 4 Using Bcrypt

#Simple Authentication with Bcrypt

This tutorial is for adding authentication to a vanilla Ruby on Rails app using Bcrypt and has_secure_password.

The steps below are based on Ryan Bates's approach from Railscast #250 Authentication from Scratch (revised).

You can see the final source code here: repo. I began with a stock rails app using rails new gif_vault

##Steps

Ejercicios Ruby
Given a sentence containing multiple words, find the frequency of a given word in that sentence.
Construct a method named 'find_frequency' which accepts two arguments 'sentence' and 'word', both of which are String objects.
Example: The method, given 'Ruby is The best language in the World' and 'the', should return 2 (comparison should be case-insensitive).
Hint: You can use the method Array#count to count the frequency of any element in the given array. eg:
[9,3,4,9,5].count(9)
Will return the value 2

Ruby Warrior - Level 4 : No new abilities this time, but you must be careful not to rest while taking damage. Save a @health instance variable and compare it on each turn to see if you're taking damage.
class Player
def play_turn(warrior)
# cool code goes here
@health = warrior.health unless @health
if warrior.feel.enemy?
warrior.attack!
elsif warrior.health < 8 or @health < warrior.health
warrior.rest!
