This will create a proxy server in whatever your availability zone your VPC is in. For me, that's us-east-1b. For you, that may be something different. Steps 10+ should more or less work regardless of your provider since those steps cover the setup and configuration of TinyProxy.

1. Click the Launch Instance button.
2. Choose Ubuntu Server 14.04 LTS (HVM), SSD Volume Type. This isn't strictly necessary. If you choose another OS, check its documentation for how to install new packages.
3. On the Choose an Instance Type screen, select t2.micro. It's Free Tier eligible.
4. Click the Next: ... buttons until you reach the Configure Security Group screen.
   • You may wish to reduce the amount of storage on the Add Storage screen. This is optional.
   • You may wish to add a tag on the Tag Instance screen. This is also optional.
5. On the Configure Security Group screen:

• Select Create a new security group.

TRZ (The Resident Zombie) - Backend

Problem Description

The world, as we know it, has fallen into an apocalyptic scenario. The "Influenzer T-Virus" (a.k.a. Twiter Virus) is transforming human beings into stupid beasts (a.k.a. Zombies), hungry to cancel humans and eat their limbs.

You, the last survivor who knows how to code, will help the resistance by deploying a system to connect the remaining humans. This system will be essential to detect new infections and share resources between the members.

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

There are many (old) clients available:

• https://github.com/tpitale/legato (active, supports API v3)
• https://github.com/activenetwork/gattica
• https://github.com/vigetlabs/garb

The Google Analytics API is at v3 (at time of writing).

This example uses Google's Ruby API client to access Analytics. Use https://github.com/google/google-api-ruby-client (Google supported).

Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.

My largest Sidekiq application had a memory leak and I was able to find and fix it in just few hours spent on analyzing Ruby's heap. In this post I'll show my profiling setup.

As you might know Ruby 2.1 introduced a few great changes to ObjectSpace, so now it's much easier to find a line of code that is allocating too many objects. Here is great post explaining how it's working.

I was too lazy to set up some seeding and run it locally, so I checked that test suite passes when profiling is enabled and pushed debugging to production. Production environment also suited me better since my jobs data can't be fully random generated.

So, in order to profile your worker, add this to your Sidekiq configuration:

if ENV["PROFILE"]

Sinatra like routes in Rails controllers

A proof of concept of having Sinatra like routes inside your controllers.

How to use

Since the router is gone, feel free to remove config/routes.rb. Then add the file below to lib/action_controller/inline_routes.rb inside your app.
