Yesterday, there was a blog post entitled "What the Hell is Happening to Rails" that stayed at the number one spot on Hacker News for quite a while. The post and many (but not most) the comments on the post reflect deep-seated concern about the recent direction of Rails.
A little over a year ago, I got my first serious glimpse at SproutCore, the JavaScript framework Apple used to build MobileMe (now iCloud). At the time, I had worked extensively with jQuery and Rails on client-side projects, and I had never found the arguments for the "solutions for
A couple weeks ago, I took the plunge and switched to vim (MacVIM, to be precise). It wasn't the first time I tried to make the switch, and I had pretty much written it off entirely. Why? Because the past few times I tried switching to vim, I took
Great web applications boot up fast and stay silky smooth once they've started. In other contexts, applications can choose quick loading or responsiveness once they've loaded. Great games can get away with a long loading bar as long as they react instantly once the gamer gets going. In
While reading Hacker News posts about JavaScript, I often come across the misconception that Ruby's blocks are essentially equivalent to JavaScript's "first class functions". Because the ability to pass functions around, especially when you can create them anonymously, is extremely powerful, the fact that both…
Today is a fairly momentous day in the history of Ruby web frameworks. You will probably find the news I’m about to share with you fairly shocking, but I will attempt to explain the situation. Before talking tech, and even going into the details of the announcement, I want
For the purposes of this post, I will be talking about JavaScript objects using syntax defined in ECMAScript 5.1. The basic semantics existed in Edition 3, but they were not well exposed. A Whole New Object In JavaScript, objects are pairs of keys and values (in Ruby, this structure
After we announced Amber.js last week, a number of people brought Amber Smalltalk, a Smalltalk implementation written in JavaScript, to our attention. After some communication with the folks behind Amber Smalltalk, we started a discussion on Hacker News [http://news.ycombinator.com/item?id=3335916] about what we should
For a while now, the Ruby community has become enamored in the latest new hotness, evented programming and Node.js. It's gone so far that I've heard a number of prominent Rubyists saying that JavaScript and Node.js are the only sane way to handle a number of
A recent post [http://reprog.wordpress.com/2010/05/12/still-hatin-on-git-now-with-added-actual-reasons/] that was highly ranked on Hacker News complained about common git workflows causing him serious pain. While I won't get into the merit of his user experience complaints, I do
Over the years, I've seen a lot of confusion about JavaScript function invocation. In particular, a lot of people have complained that the semantics of this in function invocations is confusing. In my opinion, a lot of this confusion is cleared up by understanding the core function invocation primitive,
When showing off cool features of Ruby to the uninitiated (or to a language sparring partner [http://stackoverflow.com/questions/1099305/why-is-ruby-more-suitable-for-rails-than-python/1099367] ), the excited Rubyist often shows off Ruby's "powerful block syntax". Unfortunately, the Rubyist uses "powerful block…
First Shugo announced them at RubyKaigi. Then Matz showed some improved syntax at RubyConf. But what are refinements [http://redmine.ruby-lang.org/issues/show/4085] all about, and what would they be used for? The first thing you need to understand is that the purpose of refinements in Ruby
In my previous post about generic actions in Rails 3, I made reference to significant improvements in the router. Some of those have been covered on other blogs [http://rizwanreza.com/2009/12/20/revamped-routes-in-rails-3], but the full scope of the improvements hasn't yet been
