The Daily WTF: Curious Perversions in Information Technology

Recent Representative Line

A single line of code from a large application that somehow manages to provide an almost endless insight into the pain that its maintainers face each day.

Springs are Optional

by Remy Porter in Representative Line on 2025-08-28

Optional types are an attempt to patch the "billion dollar mistake". When you don't know if you have a value or not, you wrap it in an Optional, which ensures that there is a value (the Optional itself), thus avoiding null reference exceptions. Then you can query the Optional to see if there is a real value or not.

This is all fine and good, and can cut down on some bugs. Good implementations are loaded with convenience methods which make it easy to work on the optionals.

Not What They Meant By Watching "AndOr"

by Remy Porter in Representative Line on 2025-08-26

Today's awfulness comes from Tim H, and while it's technically more than one line, it's so representative of the code, and so short that I'm going to call this a representative line. Before we get to the code, we need to talk a little history.

Tim's project is roughly three decades old. It's a C++ tool used for a variety of research projects, and this means that 90% of the people who have worked on it are PhD candidates in computer science programs. We all know the rule of CompSci PhDs and programming: they're terrible at it. It's like the old joke about the farmer who, when unable to find an engineer to build him a cow conveyer, asked a physicist. After months of work, the physicist introduced the result: "First, we assume a perfectly spherical cow in a vacuum…"
