🧩 Last Saturday, we held an in-person Puzzle Day for Harvard students. Check out the recording of our live stream for brief interviews with David, folks from Meta who provided the puzzles, as well as students solving the puzzles.
And stay tuned for the online Puzzle Day in the spring of 2024! 🚀

The CS50 Duck has a secret. Can you convince it to reveal its secret?
Join CS50 and Lakera.ai for a challenge in which you'll face none other than CS50's duck debugger, aka ddb, an experimental AI for rubberducking. But be warned: each time you crack the code, the CS50 Duck will "level up" and become more protective.
Along the way, learn about prompt engineering and, in turn, prompt-injection attacks, which can be a problem with large language models (LLMs). This challenge is a new version of the world-famous prompt-injection game Gandalf, designed specifically for CS50.
Starts 00:00 on Friday, September 29, 2023, in your own time zone. Ends 23:59 on Monday, October 2, 2023, in your own time zone. Teams of size 2, 3, or 4 are encouraged, but you may form larger teams of reasonable size. Open to anyone online, whether taking CS50 or not.

Join the live stream tomorrow at 11 a.m. EST to ask David and Carter questions! Here is the new location.
📍Harvard Biological Labs Yard
Even though we’ll be outside, the Biological Research Infrastructure is a 75,000 square foot, two-level, underground laboratory. Located below the courtyard of the Biological Laboratories, the BRI was built to house laboratory mice. 🐁
See you tomorrow 🌐
