Programming in Elixir with the Phoenix Framework

Why CoffeeScript Isn't the Answer
CoffeeScript is an open source project that provides a new syntax for JavaScript. I have to say that I have a lot of respect for CoffeeScript and it got a lot of things right. The “golden rule” of CoffeeScript is “It’s just JavaScript” . That means there is a straightforward equivalent to every line of CoffeeScript…

The best Postgres feature you're not using – CTEs aka WITH clauses
SQL by default isn’t typically friendly to dive into, and especially so if you’re reading someone else’s already created queries. For some reason most people throw out principles we follow in other languages such as commenting and composability just for SQL. I was recently reminded of a key feature in Postgres that…

The fundamental problem of programming language package management
Why are there so many goddamn package managers? They sprawl across both operating systems (apt, yum, pacman, Homebrew) as well as for programming languages (Bundler, Cabal, Composer, CPAN, CRAN, CTAN, EasyInstall, Go Get, Maven, npm, NuGet, OPAM, PEAR, pip, RubyGems, etc etc etc). “It is a truth universally…

Heartbleed and Static Analysis
The issue with things like Frama-C is that they are by far the easiest to use if you start out a project using them, and you often don’t know which projects you retroactively wished you had done so until they are big and crufty.

Creating a Bare Bones Bootloader
Upon hearing the word 'bootloader', many people cower in fear. It seems like a scary low-level thing that's very easy to mess up. To dispel some of this fear, I'm going to walk through making a super simple bootloader/OS, assuming only a basic level of familiarity with assembly language and how computers work.

Co-routines as an alternative to state machines (2009)
When you have to traverse some sort of a nested data structure (say, a binary tree), one approach is to create a stack that remembers where in the tree you are. Another, much more elegant approach, is to write the function recursively. A recursive function employs the machine stack used to implicitly implement…
