DNS to CDN to Origin  robots.thoughtbot.com
Content Distribution Networks (CDNs) such as Amazon CloudFront and Fastly have the ability to “pull” content from their origin server during HTTP requests in order to cache them. They can also proxy POST, PUT, PATCH, DELETE, and OPTION HTTP requests, which means they can “front” our web application’s origin like this: DNS -> CDN -> Origin.
I've wrote tutorial about how to add comments in Rails using commontator gem.
I released a new version of middleman-presentation:
Version Number
To make it easier to build and maybe reuse a presentation, you can now add a version number to your presentation
Custom Slide Template
Now it is possible to define a custom slide template.
Easier creation of themes
Now there's a helper command available which makes theme-creating a lot of easier.
Footer for your presentation
Now middleman-presentation displays a footer on each slide (from the 2nd slide on) with your name, the copyright and the version number
Language detection for new presentations
Now it tries to guess what's the best language to use (based on the LANG-environment variable) when you create a new slide using the slide-command
Make debugging of slides easier
With this release you find HTML-comments with the file name in the rendered output.
Hello, Using Ruby build scripts, that is, rake tasks, I've built up a new GitHub org, that is, beer.csv - for open beer data in the CSV (comma-separated values) format, that is, plain old text. To get started I've added - for a change - beer statistics such as production, imports, exports, consumption, consumption per head, etc. for countries. Cheers. Prost. Salud. Kampai.

You want to test-drive some code, but you're stuck. Maybe you're not totally sure what your object's interface should look like. You might not be sure you can test what you're thinking of building. Or you could be procrastinating, because you just don't feel like writing tests right now. How do you get the benefits of TDD when you don't feel like TDDing?
In short tutorial, I will explain how to use acts_as_votable gem to create voting system in Rails app.
Ruby: Introduction

Red is the color of love, passion, vivacity, exuberance, and power. It is also the color of one of the most beautiful gemstones in the world -the ruby. The ruby is known to be the July birthstone and is the stone given on the 15th and 40th marriage anniversaries to provide happy couples a long prosperous marriage. In ancient times the ruby is known as the "king of gems". The ruby has everything a precious stone would need- magnificent color, excellent hardness, and outstanding brilliance. The color of a ruby can range from fiery orange red to a deep purple red. Large rubies are hard to find, which make them rare, in some cases could be more valuable than a diamond of the same size.

Ruby: History

ActiveResource can be pretty helpful when you have a RESTful JSON API. Although it has some limitations. One of the most irritating is a lack of nested resources #new scope method. Luckily there's a way to make it work exactly as its ActiveRecord equivalent. For more details, plese refer to this post: ActiveResource relations – a bit of magic to make it look and feel more like ActiveModel relations

This is the second post in a series about getting to know RubyMotion. At the end of the previous post we had something on screen and had learnt some core principles of iOS development with RubyMotion, now we're going to get ourselves organised using classes for a controller and a view, and get some interaction going in the next part of the series, Gaining Control of RubyMotion with UIViewControllers

Starting A RubyMotion Application  blog.motioninmotion.tv

Part one is introducing you to the basics of just getting something on the screen and pointing out some core differences between most Ruby implementations and RubyMotion. http://blog.motioninmotion.tv/starting-a-rubymotion-application
Last night, I set up an SEO keyword tool and a Twitter+Facebook retargeting tool for seven different websites. Both tools require I add JavaScript snippets to my websites but I didn't touch my codebases or deploy anything new.

I got it done by using Segment.io, which I've been using for about a year as the primary "Adapter Pattern" for all analytics on my Ruby on Rails apps, Middleman apps, Rack apps, and other static sites. I have Google Analytics and Intercom set up through it and all kinds of other email, customer retention, and analytics tools.

In sum, those tools help me understand whether the things I've built are things that any users or customers actually want, helps me drive traffic to them, and help me grow the products.

Sometimes it's better to interact with Segment.io from the server-side, though. In Segment.io and Ruby, Josh talks about how to do it cleanly and in a testable way from inside a Rails app, with RSpec matchers.

I'm proud to announce the initial release of Roda, a new ruby web framework based on the following ideas:

1) Use a routing tree, similar to Cuba and Rum
2) Make it easy to use like Sinatra
3) Make it extensible like Sequel
4) Avoid namespace pollution

Find out why you should use Roda
attr_searchable, the gem to add database agnostic fulltext search to ActiveRecord (for Mysql and PostgreSQL) is a young and ambitious project. As its set of features grew, it has become neccessary to change its DSL and name. Thus, 'attr_searchable' is called 'search_cop' now.

In addition to the new name, search_cop v1.0.0 is out now and ships with search_scope's:

Check it out and install or migrate to 'search_cop'
