Scala – 1 Star – Would Not Program Again
With Scala you feel smart having just got something to work in a beautiful way but when you look around the room to tell your clojure colleague how clever you are, you notice he left 3 hours ago and there is a post-it saying use a Map. Daniel Worthington-Bodart

Clojure from the ground up: Macros
In Chapter 1 , I asserted that the grammar of Lisp is uniform: every expression is a list, beginning with a verb, and followed by some arguments. Evaluation proceeds from left to right, and every element of the list must be evaluated before evaluating the list itself. Yet we just saw, at the end of Sequences , an…

String types are fine. How about your code?
Someone on the internet says that strings are broken, and some more people on the internet disagree. The problem is that all kinds of common operations on strings, such as counting the amount of ch…

The string type is broken
My previous article, “We don’t need a string type“, caused a bit of stir. Though the feedback is mixed, there is a common theme of a string being a useful feature. After doing a bit more research I can determine only one thing: most current string types are broken! Many of us believe our strings […]

Boundaries
This talk is about using simple values (as opposed to complex objects) not just for holding data, but also as the boundaries between components and subsystems. It moves through many topics: functional programming; mutability's relationship to OO; isolated unit testing with and without test doubles; and concurrency, to…

How statically linked programs run on Linux
In this article I want to explore what happens when a statically linked program gets executed on Linux. By statically linked I mean a program that does not require any shared objects to run, even the ubiquitous libc . In reality, most programs one encounters on Linux aren't statically linked, and do require one or…

Node.js Stream Playground
This summer I had the opportunity to attend NodeConf and it was a fantastic experience. I really appreciated how every session was a hands-on coding session: I felt like I walked away knowing how to put a bunch of advice directly into practice.

My tmux setup
I’ve been using tmux as my main terminal multiplexer for about 3 years now and have refined my configuration over time to fit my daily workflow.
