Pradeep's Ruby on Rails Blog | RoR for developers Goliath Goliath is an open source version of the non-blocking (asynchronous) Ruby web server framework powering PostRank. It is a lightweight framework designed to meet the following goals: bare metal performance, Rack API and middleware support, simple configuration, fully asynchronous processing, and readable and maintainable code (read: no callbacks). The framework is powered by an EventMachine reactor, a high-performance HTTP parser and Ruby 1.9 runtime. One major major advantage Goliath has over other asynchronous frameworks is the fact that by leveraging Ruby fibers introduced in Ruby 1.9+, it can untangle the complicated callback-based code into a format we are all familiar and comfortable with: linear execution, which leads to more maintainable and readable code. Each Goliath request is executed in its own Ruby fiber and all asynchronous I/O operations can transparently suspend and later resume the processing without requiring the developer to write any additional code.

Puma Getting Started with Rails 1 Guide Assumptions This guide is designed for beginners who want to get started with a Rails application from scratch. It does not assume that you have any prior experience with Rails. Rails is a web application framework running on the Ruby programming language. If you have no prior experience with Ruby, you will find a very steep learning curve diving straight into Rails. There are several curated lists of online resources for learning Ruby: Be aware that some resources, while still excellent, cover versions of Ruby as old as 1.6, and commonly 1.8, and will not include some syntax that you will see in day-to-day development with Rails. 2 What is Rails? Rails is a web application development framework written in the Ruby programming language. Rails is opinionated software. The Rails philosophy includes two major guiding principles: 3 Creating a New Rails Project The best way to read this guide is to follow it step by step. 3.1 Installing Rails Open up a command line prompt. 4 Hello, Rails!

Slow clients should only be served by placing a reverse proxy capable of fully buffering both the the request and response in between unicorn and slow clients. Features Designed for Rack, Unix, fast clients, and ease-of-debugging. We cut out everything that is better supported by the operating system, nginx or Rack.Compatible with Ruby 1.9.3 and later. unicorn 4.x remains supported for Ruby 1.8 users.Process management: unicorn will reap and restart workers that die from broken apps.

It’s a shame, because it’s a great database (I’ve been using it for personal and some work projects for years, like my current side project, sendcat). Luckily it’s now really simple to get it going on your Mac to give it a try. This is how you do it. What this guide is This is a guide to getting PostgreSQL running locally on your Mac, then configuring Rails to use that for development. What this guide is not An advanced PostgreSQL guide.Suitable for using in production.Anything to do with why you might want to use PostgreSQL over any other database. Installation You can get binaries for most systems from the Postgresql site, but it’s even easier if you’ve got homebrew installed, if you haven’t got homebrew it’s worth it, pick it up here. With homebrew just run: $ brew install postgres brew info postgres $ initdb /usr/local/var/postgres Done!
