“You’re not really a developer. Sooner or later people are going to realize you don’t know what you’re talking about. You’re just not good enough.” You’ve probably had thoughts like these at one point or another. You’ve never heard someone else tell you that you’re not a developer, but you’re still thinking it. You may be thinking along these lines…

My mom has a tendency to buy these really terribly spec’d Windows machines. She’s been doing it for as long as I’ve been alive. I was surprised when on one of our latest Zoom calls she said “You know what, I’m beginning to think that size matters.” I’ve only been telling her this for years! Here’s the problem. There are…
Steganography. The art of hiding something right under your nose. For as long as humans have been alive, we’ve been trying to hide things — whether it’s our last slice of pizza or the location of a buried treasure. Do you remember the cool invisible lemon ink trick, where we’d write the secret message with lemon and heat the paper…
LibreSSL is a fork of OpenSSL that improves code quality and security. It was originally developed for OpenBSD, but has since been ported to several platforms (Linux, *BSD, HP-UX, Solaris, macOS, AIX, Windows) and is now the default TLS provider for some of them. When debugging a program that uses LibreSSL, it can be useful to see decrypted network traffic.…

Per the overlapping interfaces proposal, Go 1.14 now permits embedding of interfaces with overlapping method sets. This is a brief post explain what this change means: Let’s start with the definition of the three key interfaces from the io package; io.Reader, io.Writer, and io.Closer: Just as embedding a type inside a struct allows the embedded type’s […]

In Go, how do you run several operations that might return an error, and return those errors at the end? Here's how I do it.
In my book I discuss the importance of context in reading and writing mathematics. An early step in becoming comfortable with math is deciphering the syntax of mathematical expressions. Another is in connecting the symbols to their semantic meanings. Embedded in these is the subproblem of knowing what to call the commonly used symbols. The more abstract you go, the…

Conventional wisdom dictates that the larger the number of types declared in a Go program, the larger the resulting binary. Intuitively this makes sense, after all, what’s the point in defining a bunch of types if you’re not going to write code that operates on them. However, part of the job of a linker is […]
