Because implementing obsolete programming languages is a great use of my free time, I've created cxxforth, an implementation of Forth in C++.
Inspired by JONESFORTH, I wrote it in the style of a tutorial. The source code is automatically converted to a pretty-printed format: https://github.com/kristopherjohnson/cxxforth/blob …
I ran across a question on Quora: What's the easiest programming bug you spent way too much time trying to solve?.
Here is my answer to that question. Some time during my first few years of programming, I wrote code similar to this little snippet and expected it to print …
Stack Overflow is an amazing resource for computer programmers. I've asked a lot of questions there, and answered a lot of questions there, and I've found the answers to lots and lots of questions that someone else has already asked. Participating in Stack Overflow has been great.

I often wonder how kids today get into programming. When I was a kid, and got my first computer, I spent a lot of time typing in the programs from David Ahl's BASIC Computer Games. After typing in the code for the games and playing them a bit, I'd start …
Early in my career, I prided myself on my ability to absorb a lot of information and stay up-to-date on programming tools and techniques. I learned C++ before any of my colleagues did, and knew more about its intricacies than they did. I implemented ActiveX control containers before most people …

Based on its pedigree, I expect this …
This is a quote I like:
The really good programmers spend a lot of time programming. I haven't seen very good programmers who don't spend a lot of time programming. If I don't program for two or three days, I need to do it. And you get better at it …
While working on an iPhone application, I decided I wanted to change the colors of the background and section headers of a UITableView with the UITableViewStyleGrouped style. It took a lot more work than I expected, so I'm sharing what I learned with anyone else who needs to do this …
My Menubar Countdown application uses an NSStatusItem to display itself in the menu bar. I recently had to add a custom view to that status item, and thought I'd share what I learned about the process here.
A little background: a status item is one of those little thingees you …
While learning about Core Animation, I was disappointed to find that it is plagued by the anti-pattern that I call the Overly Generic Interface.
The Overly Generic Interface is an interface that provides a very small set of functions, but each function takes parameters that allow one to do a …
