Using the OS X 10.10 Hypervisor Framework: A Simple DOS Emulator
Since Version 10.10 (Yosemite), OS X contains Hypervisor.framework, which provides a thin user mode abstraction of the Intel VT features. It enables apps to use virtualization without the need of a kernel extension (KEXT) – which makes them compatible with the OS X App Store guidelines.

Richer command line interfaces
This post is preceded by a description of two types of command line interfaces . The more command line-like of these two types integrates into a normal shell session ( python , telnet , bash ) instead of using the alternate screen to present a fullscreen text user interface ( top , vim , emacs ). Sometimes programs…

TIS-100: the Programming Game You Never Asked For
You know what’s universally regarded as un-fun by most programmers? Writing assembly language code. As Steve McConnell said back in 1994: Programmers working with high-level languages achieve better productivity and quality than those working with lower-level languages.

Ditching tmux
This week I started an experiment. I wanted to know whether I would be able to completely ditch tmux. Don’t get me wrong here, I absolutely love how tmux makes terminal multiplexing transparent for me. I’m also very used to <C-b>c, <C-b>1-0 and so on. I also have a custom set of keymaps and plugins I use frequently…

Interfaces – The Most Important Software Engineering Concept
An interface can be thought of as a contract between the system and the environment. In a computer program, the 'system' is the function or module in question, and the 'environment' is the rest of the project. The interface formally describes what can pass between the system and the environment. An 'implementation'…

Mistakes Beginners Make When Working with Databases
When you start out as a developer there’s an overwhelming amount of things to grasp. First there’s the language itself, then all the quirks of the specific framework you’re using,and after that (or maybe before) we’ll throw front-end development into the mix, and somewhere along the line you have to decide to store…

This article is about summarizing my thoughts on recent events. Rather than yet another rant about the state of web development, this piece aims to pour some thought into what…
