John Resig - Simple JavaScript Inheritance
I’ve been doing a lot of work, lately, with JavaScript inheritance – namely for my work-in-progress JavaScript book – and in doing so have examined a number of different JavaScript classical-inheritance-simulating techniques. Out of all the ones that I’ve looked at I think my favorites were the implementations…

Staying the hell out of insert mode (vi)

Clojure Protocols can extend final Java classes (like java.lang.String)
Clojure is written in terms of abstractions. There are abstractions for sequences, collections, callability, etc. In addition, Clojure supplies many implementations of these abstractions. The abstractions are specified by host interfaces, and the implementations by host classes. While this was sufficient for…

This isn’t one of the things my group at Google has asked me to look at, but I think it’s worth doing and worth some of my time. I’m writing this today because I’m amused by the contrast with the…

Apple Slaps Developers In The Face
[Adobe would like me to make it clear that the opinions below are not the official views of the company and are entirely my own.] By now you have surely heard about the new iPhone 4.0 SDK language that appears to make creating applications in any non-Apple-approved languages a violation of terms.
