OSX Mavericks has been crashing randomly recent to me. Just very random. Not quite good because it doesn't give it the chance for processes like Postgres, etc... to shut down properly, leaving process ids (PIDs) behind.

Now got this issue where my postgres won't boot up.

Running postgres manually doesn't work

> pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
> pg_ctl: another server might be running; trying to start server anyway
So here's a quick fix.

require 'rails_helper'

RSpec.describe TodosController, :type => :controller do

  context "GET index" do
  #context "POST create" do
  #context "GET show" do
  #context "PATCH update" do (or PUT update)
  #context "DELETE destroy" do
  #context "GET new" do

for i in `gem list --no-versions`; do gem uninstall -aIx $i; done

git branch -m old_branch new_branch         # Rename branch locally    
git push origin :old_branch                 # Delete the old branch    
git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote

I was having the same problem. Ubuntu 14,04 here. I found this answer in a forum that solved the problem for me.

After struggling a bit, I found some useful commands. You can type these in any skype chat window.

/dumpmsnp - show details about your connection

/showplaces - show where you are currently connected

What was happening was that /dumpmsnp command was showing "LoggedOut", but I was online and talking almost normally (except group chats).

Transactions

As your business logic gets complex you may need to implement transactions. The classic example is a bank funds transfer from account A to account B. If the withdrawal from account A fails then the deposit to account B should either never take place or be rolled back.

Basics

All the complexity is handled by ActiveRecord::Transactions. Any model class or instance has a method named .transaction. When called and passed a block, that block will be executed inside a database transaction. If there's an exception raised, the transaction will automatically be rolled back.

Example

class FlatArray
  attr_reader :nested_array, :result

  def initialize(nested_array = [])
    @nested_array = nested_array
    @result = []
  end

 def call
