A few weeks ago, I started a kickstarter project to fund work on a project to make a long-term, sustainable binary build of Ruby. The outpouring of support was great, and I have far exceeded my original funding goal. First, I'd like to thank everyone in the community who contributed…

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 JavaScript and Ruby…

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 about what we should do. Most people told us to stick…

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…

The primary reason I enjoy working with Rubinius is that it exposes, to Ruby, much of the internal machinery that controls the runtime semantics of the language. Further, it exposes that machinery primarily in order to enable user-facing semantics that are typically implemented in the host language (C for MRI,…

Over the past few years, I have occasionally expressed frustration (in public and private) about the process for approving new features to the next edition of ECMAScript. In short, the process is extremely academic in nature, and is peppered with inside baseball terms that make it nearly impossible for lay…

For a few years, a group of Japanese academics have been working on formalizing the Ruby programming language into a specification they hoped would be accepted by ISO. From time to time, I have read through it, and I had one major concern. Because Ruby 1.9 was still in…

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…

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, and…

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…
