Oh, Go Ahead, Overthink FizzBuzz (2008)
I gave the best programming interview answer I may have ever given last Friday. The interviewer hauled out FizzBuzz and asked me to solve it. It took me a minute to stop laughing. FizzBuzz is a brain-dead simple programming problem, used pretty much to tell if a developer has a pulse at all. It is…

Strange C Syntax
In my attempts to learn the C programming language well enough to write my own C compiler , I've encountered some very interesting examples of C syntax that you generally don't see every day.

Why We Use Go
Go is decidedly polarizing. While many are touting their transition to Go, it has become equally fashionable to criticize and mock the language. As Bjarne Stroustrup so eloquently put it, “There are only two kinds of programming languages: those people always bitch about and those nobody uses.” This adage couldn’t be…
