Git is the source code version control system that is rapidly becoming the standard for open source projects. It has a powerful distributed model which allows advanced users to do tricky things wit…
I have been reading Doom Guy by John Romero. It is an excellent book which I highly recommend. In the ninth chapter, John describes being hit by lightning upon seeing Adaptive Tile Refresh (ATR). That made me realize I never took the time to understand how this crucial piece of tech powers the Commander Keen (CK)…
Your Makefiles are full of tabs and errors. An opinionated approach to writing (GNU) Makefiles that I learned from Ben may still be able to salvage them.

Imagine if you could auto scale simply by wrapping any existing app code in a function and have that block of code run in a temporary copy of your app

Most command line programs that offer line editing -- like bash, Python, GDB, psql, sqlite and more -- do so using GNU readline. Readline's a powerful library that grants history, completion, movement and editing to programs that use it --- and a stable and consistent set of keyboard shortcuts. Shame, then, that even…
