In this blog post from 2014, the author reflects on their early days as a videogame programmer at a startup called SingleTrac. The post recounts a moment when the team celebrated getting a black triangle to appear on the screen, much to the confusion of the company’s financial controller. However, the triangle symbolized an important milestone in the development process, showing that the foundation for a complex system was complete. The term “black triangle” became a metaphor for significant but less visible accomplishments. The author encourages readers to use the term when they encounter similar situations in their own work.
