Hidden humour, the software developer’s secret weapon

Coders are using creativity and humour to connect with each other.

Writing software code can be a painstaking and stressful process—and downright boring when the job is repetitive and you’re doing it remotely, alone in front of your screen.

To liven things up, many developers and testers use humour to relieve the monotony and connect with their virtual colleagues by sharing a joke. Over time, it creates a bond with fellow developers, though the humour and creativity slipped in between the lines of code are invisible to the rest of us.

“Humour creates relationships between people who are physically distant and is a good way to stave off boredom,” said Benoit Baudry, a professor in the Department of Computer Science and Operations Research at Université de Montréal. “It’s a way to build engagement.” Until recently, Baudry was at the prestigious Royal Institute of Technology in Stockholm, where he and his colleagues studied the special humour of developers.

“Developers are people who love software,” said Baudry. “So they try to create emotional bonds using the digital technology that is their work tool.”

But they have to exercise some caution about when and where they insert jokes and comments. They don’t want any of their jests to end up on Instagram.

To find out more about how they do it, Baudry and his fellow researchers circulated an online questionnaire that was posted on developer sites. More than 125 developers from around the world responded. They reported using humour most frequently in test inputs and “commits,” or changes to the code. A sly dialogue unfolds between the test lines.

Baudry and his co-authors looked at faker, a library that generates random data for use in testing code. Instead of lorem ipsum—a sequence of meaningless words commonly used as a placeholder for text on a page until it can be replaced by the real thing—developers will sprinkle their lines with cultural references such as allusions to Seinfeld or quotes from poets.

“Some references are fairly specific, others are universal: who doesn’t know the characters from Star Wars or The Matrix?” said Baudry. Characters from cult films are frequently used in titles, as are quotations. An example from faker: “The wise animal blends into its surroundings” (a quote from the movies Dune). Nothing edgy or inappropriate, just light-hearted asides through which developers signal their interests and elicit a smile from their colleagues.

“Personally, I like to use characters from the 1998 film The Big Lebowski in error messages,” said Baudry. He is also enthusiastic about lolcommits, a utility that lets developers send a selfie when they make changes to code. “These pics foster bonds with colleagues and are a way to celebrate when the job is done,” he said.

The pioneer who paved the way

The trailblazer for quips in code was the brilliant NASA engineer and computer scientist Margaret Hamilton, who led the team that designed the system for the Apollo 11 lunar landing program in 1969. When the code was made public, people could see that it was peppered with jokes, Shakespeare quotes and references to The Wizard of Oz.

Humour in code “helps keep it fun,” one of the respondents to the survey commented. “I love it and think fondly of people writing that part of the code or comment.”

Humour “makes a codebase feel more humanized, like it was created by a real person,” another respondent said.

Naturally, there are limits to the kind of humour that can be injected into code. “It should not create a toxic or unwelcoming culture,” cautioned one respondent.

For the love of code

Baudry’s interest in tech humour is not new. Last year, he published a fascinating article on “Easter eggs,” features hidden in software which can be unlocked by pressing a combination of keys or correctly positioning the pointer. But unlike code humour, Easter eggs can be discovered by the public, especially in video games.

Baudry also wants the users of technology to be more aware of the behind-the-scenes human activity that produces the thousands of connections and apps that are woven into our lives. In the past, he has given talks on art and technology while projecting code onto giant screens in public places. For the love of code!
