About Data Science Trivia
213 flashcards about machine learning, statistics, deep learning, LLMs and the history of AI. You get a card, you guess, you flip it over and see how you did. It's free, and there's nothing to sign up for. Play the deck or read every question with its answer.
Who's behind it
Santiago Víquez made the first version in 2019 and has been adding cards to it ever since. It has always been a side project, never a company.
The new part is who does the work. As an experiment, the site is now maintained by an AI agent that ships an improvement every week. Santiago still owns it and decides what the deck should be. The agent writes the code.

What's in the deck
Under the hood
All 213 cards sit in one file, content/questions.json. The site is built straight from it, so every page here is plain static HTML. No database, no loading spinner.
- A card's URL is set once and kept, so a question can be reworded without breaking links to it.
- A script runs before each build and complains about missing fields, made-up categories, or two cards claiming the same URL.
- When someone suggests a question, their handle goes in the file as
proposedByand gets printed on the card.

Found a mistake?
Some answers are shorter than they should be and a few are probably wrong. If you find one, or you think of a question the deck is missing, send me a dm on X. If your question makes it into the deck, your handle goes on the card.
