All Software is Legacy
In what may be judged in years to come as a moment of madness, I have volunteered to be the primary maintainer of the Perl CGI module (CGI.pm). For the non-technical readers of this post: CGI.pm is a few thousand lines of code that in the mid to late nineties, and even some years later, was helping many websites…

Scala’s Types of Types
This blog post came into being after a few discussions about Types in Scala after some of JavaOne’s parties in 2013. After those discussions I figured that many questions are often repeated by different people, during their learning of Scala. I though that we didn’t have a full list of all tricks what we can to with…

How to Name Clojure Functions
This is a guide on naming Clojure functions. There are exceptions to every rule. When you’re defining something based on natural language, there are more exceptions than rules. I break these rules more often than I follow them. This guide is just a starting point for thinking about how to name things.

Emacs Bytecode Internals (2014)
Byte-code compilation is an underdocumented — and in the case of the recent lexical binding updates, undocumented — part of Emacs. Most users know that Elisp is usually compiled into a byte-code saved to .elc files, and that byte-code loads and runs faster than uncompiled Elisp. That’s all users really need to know…

Inspecting C's qsort Through Animation
The C standard library includes a qsort() function for sorting arbitrary buffers given a comparator function. The name comes from its original Unix implementation, “quicker sort,” a variation of the well-known quicksort algorithm. The C standard doesn’t specify an algorithm, except to say that it may be unstable (C99…

LeftPad and Go: can tooling help?
You’ve probably heard that story about NPM community and LeftPad package, that broke thousands JavaScript projects worldwide. There was a nice follow-up article titled “Have We Forget How To Program” and one guy even created left-pad.io - Left-Pad As A Service web service. People got a lot of fun discussing this story.

Dijkstra's Algorithm
I was at SCNA the other day, and someone approached me about TDD and Dijkstra’s algorithm. He wondered if you could find a sequence of tests that would lead you to the algorithm. This sounded like a fun little exercise, so I decided to give it a try here.

Strategic Scala Style: Principle of Least Power
The Scala language is large and complex, and it provides a variety of tools that a developer can use to do the same thing in a variety of ways. Given the range of possible solutions to every problem, how can a developer choose which one should be used? This is the first in a series of blog posts aiming to provide…

When code is suspiciously fast: adventures in dead code elimination
Part of a recent assignment for one of my classes involved calculating the Fibonacci sequence both recursively and iteratively and measuring the speed of each method. (BONUS: For a fun diversion, here is a paper I wrote about using the Golden Ratio, which is closely related to the Fibonacci sequence, as a base for a…

The Elixir of concurrency
Elixir is a fairly young language that was born when José and a few Rails developers tried to create a modern language optimized for concurrent, distributed, lightweight processes They wanted a modern Ruby-like syntax with a well-tested process ma
