Post-REST
More or less all the big APIs are RESTful these days. Yeah, you can quibble about what “REST” means (and I will, a bit) but the assertion is broadly true. Is it going to stay that way forever? Seems unlikely. So, what’s next?

C Portability Lessons from Weird Machines
In this article we’ll go on a journey from 4-bit microcontrollers to room-sized mainframes and learn how porting C to each of them helped people separate the essence of the language from the environment of its birth. I’ve found technical manuals and videos for this article to help bring each computer to life.

Things nobody told me about being a software engineer
My dad started teaching me Basic when I was about 7 years old, and since about that age I knew that I wanted to build software for a living. It was obviously a fun and useful thing to do, and something that I could do well. But there is a big — and I mean Grand Canyon-scale BIG — difference between “programming” and…
