A TypeScript & alt JS grab bag
Various and sundry observations about altJS languages, with a focus on TypeScript.
Modeling union types using only functions
The lambda calculus is the basis for functional programming. Church's encodings in the untyped lambda calculus show an interesting pattern that parallels union types in languages like Haskell. Here I try to show how these discriminated union types can be implemented using only javascript functions.
ANN: Color.js 1.0
color.js, my color management library for JavaScript, has hit 1.0.

duck-wrapping types
Duck-wrapping
If it doesn't quack like a duck, wrap it in a duck. Or don't.

The Clojure web stack and the CRUD stack
Why it is my opinion that Clojure is better off with out a CRUD web framework.
Reconsidering the relevance of design patterns
Design patterns fell out of favour in the last five or so years. I think there is still some value in them.

CoffeeScript comprehensions are broken
An examination of List Comprehensions in several languages, how Coffeescript's ‘comprehension’ semantics differ from the common case, and limitations that arise.
A brief overview of the Clojure web stack
Ring is the foundation of web programming in Clojure. It has a broad ecosystem of libraries that fullfil many different roles in the web stack. This article introduces the fundamental concepts of Ring as well as four major libraries, and explains common idioms to help you get started quickly.
Parsers generating parsers
Following my introduction to fnparse, this article looks at how more common functional programming tools can be leveraged to make parsers that output new parsers.
Start parsing in Clojure: fnparse
Parser combinators are a powerful way of expressing complex parsers as first class operations in a language with first class functions. This tutorial introduces one such library, fnparse, for Clojure.
