Simply encrypt and decrypt Strings in Ruby.
require 'openssl'
class String
def encrypt(key)
cipher = OpenSSL::Cipher.new('DES-EDE3-CBC').encrypt
cipher.key = Digest::SHA1.hexdigest key
s = cipher.update(self) + cipher.final
s.unpack('H*')[0].upcase
end

Comparison of our core Rails app using Webrick, Puma, and Unicorn. Almost no effort was made to optimize either application server. Tests were performed on a MacBook Air using `siege` to hit the application homepage.

TL;DR

Unicorn was by far the best performing (5.94 trans/sec over the 1-minute test, 352 total). Puma (3.95 trans/sec, 235 total) appeared to perform no better than Webrick, despite the default behavior of using up to 16 threads. Perhaps increasing its worker count to the number of cores will improve its performance.

I've tried to run multiple Puma workers with the workers directive (per their sample documentaiton), but I receive errors about undefined method 'workers' for #<Puma::Configuration::DSL:0x007ffca4bde798>).

Ubuntu 12.04 Ruby, Rails, Nginx, Unicorn

Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

  • Create new server
  • Login to new server
    • ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
    • accept the RSA key

Create a branch on Github without access to a local git repo using http://hurl.eu/

Ever had the need to create a branch in a repo on Github without wanting (or being able) to access a local repo?

With the aid of [the Github API][1] and any online request app this is a piece of cake!

Just follow these steps:

  1. Open an online request app (like apirequest.io, hurl.it pipedream.com, reqbin.com, or webhook.site)
  2. Find the revision you want to branch from. Either on Github itself or by doing a GET request from Hurl: https://api.github.com/repos/<AUTHOR>/<REPO>/git/refs/heads
  3. Copy the revision hash
  4. Do a POST request from Hurl to https://api.github.com/repos/<AUTHOR>/<REPO>/git/refs with the following as the POST body :
