Testing things that take time nathanmlong.com
Have you ever needed to test something like this?
- Hit URL A
- Wait (how long?)
- Find results at URL B
The ideal is to wait "just long enough" before getting the results. This short post shows a simple way to do that.

I've used a lot of Todo applications, but I never really liked any of them. Really, what I like to use is a text editor and just create a simple list manually. However, I like having notifications. Thus, TODO Notifier

The Ruby gem Rattler is designed to make language design and recognition as simple and fun as possible. It's nearly ready for a 1.0 release, but unfortunately I have so little time to work on it that progress is slow.
I'm looking for a few good Rubyists to join the team and help take this over the finish line, and beyond!
If you've ever wanted to design your own programming language, or even just implement a parser for an existing language in Ruby, and found other tools to be difficult to understand and use, Rattler is for you!
If you'd like to be part of making Rattler the language design tool of choice, message me on twitter: @jarhart
Thanks!

Which Ruby implementation is right for your project? While the reference implementation (Ruby MRI) remains the interpreter of choice, an alternate Ruby implementation may be right for your project, depending on your operational goals and constraints. This article showcases the Ruby interpreter implementations and runtimes available today, discussing the advantages and disadvantages of each.
Shared Terminology Yet Different Concepts Between Ember.js and Rails robots.thoughtbot.com
Developers who are well versed in Ruby on Rails (or other MVC implementations) and start learning Ember.js may find it surprising that, even though there’s shared vocabulary, denoted concepts are sometimes very different.
The first and obvious difference comes from the fact both are web frameworks. Rails facilitates the creation of web apps that offer mainly an HTTP interface to interact with. On the other hand, Ember helps creating web apps that interface directly with humans (through clicks, taps, key presses, etc). They are both web application frameworks, but the former is server side and the latter client side.
A look into their workflows will shed light over the main differences.

Controller-specific assets with Rails 4 theflyingdeveloper.com

I recently found that despite appearances, all your controller-specific asset files (i.e. assets generated with "rails g controller blah") are actually loaded into every page.
This post explains how to change this behaviour and get the assets loading where you expect.

I gave a talk recently about working with an old codebase (particularly an old rails codebase, though the ideas are applicable more broadly). Here is a video! This is the abstract:
Sometimes you get to start fresh, with the latest version of ruby, the latest web server, the latest database, and your choice of dependencies. But sometimes, you have to work with an old codebase. This codebase might have been started years ago, by tens or hundreds of people, many of whom no longer work for the organization. This talk is the story of one such codebase, and how to work with it every day.

Automatic, parallel stages in the cloud teatro.io
New service Teatro.io for automatic rails stage.
I just published an article that covers open source security libraries, web services, and reads that any developer should consider before implementing their next Ruby app.
How do you choose the right libraries for your Rails app? justinweiss.com
Angular vs Ember. RSpec vs Minitest. Haml vs Slim vs ERB. You have so many choices to make when you start a new project. There are vocal defenders on each side. And soon you realize that you could have started your project in the time you’ve wasted reading that fourth tutorial or 30-comment thread about whether Sass is better than Less. How can you choose the right library, so you can start writing actual code?

This release fixes a pesky bug where inheritance was broken for column colors. Check out the wiki to see examples of nicely formatted tables. As always the gem is available on rubygems.org with source on github. For those not familiar with "the reporter", it provides a ruby DSL for writing reports with built in features for progress reporting and table formatting. It is very handy for system level and data reporting scripts.
Container controllers, such as UINavigationController or UITabBarController are the core navigation mechanism for many of our applications. The UIKit framework provides us with mechanisms and direction to create our own custom container controllers, which we'll be covering in this episode.

Composition should be preferred, but beware of the unexpected behaviors. This is my personal experience: Three Things To Know About Composition.

Hello, I've created a new GitHub org, that is, wikiscript, that collects (Ruby) scripts that let you turn free-style or semi-structured wiki text into open structured data. A first example is the new football squads reader that reads in a wikitext page and outputs all squads files in the football.db format - so you get an up-to-date World Cup 2014 squads list including all 736 player (32 teams x 23 players). (By the way, three days to kick-off and counting!) Cheers.

I just published DuckPond - a gem for getting around some of the shortcomings of duck typing in a weakly typed language such as ruby.
"swift-ruby" is designed to bring over some good features from Apple's new Swift language to Ruby:
https://github.com/galori/swift-ruby
I implemented only one thing, the ? Optional method operator..please jump in and submit some Pull Requests!
Background:
I just came from Apple's WWDC and watched their introduction of the new Apple Swift programming language.
From Chris Lattner, a Swift developer at Apple personal site: "Of course, it also greatly benefited from the experiences hard-won by many other languages in the field, drawing ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list."
The ? Optional operator is equivalent to ActiveSupport's "try":
The active support version would look like this:
The Swift-Ruby version:
So, clone the repo: https://github.com/galori/swift-ruby, see Apple's reference: https://developer.apple.com/swift/, and submit some PR's.

How to Learn TDD Without Getting Overwhelmed justinweiss.com
The culture of testing is one of the best things about the Rails community. But if you’re coming from a place where you weren’t testing at all, TDD can be especially hard to learn. It’s clear that you can’t really go from zero to TDD in a single step. So, what do you do? How can you learn TDD without being overwhelmed?

My own history
I have been coding since I was thirteen, when my Father came home with old IBM clone that he traded for during the 80’s barter craze. Being nearly forty years old now, I have stubbed my toe and left it bleeding in more than a dozen languages now. If I were a construction worker instead of a knowledge worker, I would probably be missing fingers, toes, and possibly a hand or leg.
