The @CS50 Show. This Wednesday on YouTube.

This is #50seconds on Binary Digits with Professor @davidjmalan.

Join us for the second-annual CS50x Puzzle Day at Oxford! CS50 is back in the United Kingdom! Join us at the University of Oxford on Friday, November 6, 2026, 5pm–10pm, for a CS50x Puzzle Day in collaboration with Oxford Lifelong Learning, with Professor @davidjmalan from @Harvard, Professor Daniel Wilson from @UniofOxford, Professor Nicholas Day from Oxford, and Professor Tom Crawford from Oxford (and Cambridge and @tomrocksmaths). CS50x Puzzle Day is an opportunity to collaborate on teams of 2, 3, and 4 to solve a packet of puzzles (i.e., logic problems). Among the event’s goals is to send a message that computer science is more about problem-solving than it is about, say, programming. Puzzles are not programming challenges. No prior CS or programming experience needed, just logic and smarts! No team? No problem! We will help teams form at the event. Tickets on sale until 4pm on November 4, 2026. eventbrite.com/e/cs50x-puzzl…

“What concerns me most is not only that things like the Hugging Face incident can happen without our initially knowing about or understanding them — but how quickly they can happen.” In this interview for The Harvard Gazette, Professor @davidjmalan talks about the @CS50 Duck, the changing landscape of AI, and the future of computer science education. news.harvard.edu/gazette/sto…

“It’s been fairly well-documented that even when you are not proactively revealing much about yourself, your devices are, your browsers are, your behaviors are, so typically by nature of what you’re clicking on, what sites you’re visiting, how long you’re spending on them, social media companies can create a profile about you… because they’re detecting patterns in those behaviours of yours.” Professor @davidjmalan goes on ABC’s Radio National Breakfast to talk about the nature of social media algorithms and what their regulation could look like. abc.net.au/listen/programs/r…

An online version of @CS50 will again be offered through the @UniofOxford, starting September 14, 2026! Students in the course will meet weekly online with an Oxford tutor, Dr Nicholas Day, and, upon successful completion, will be eligible for a University of Oxford digital certificate. If you or someone you know might like to take the course, apply at cs50.uk. Or send them piped.video/R03gZT5H3Bk! Dr Nicholas (Nick) Day is a Departmental Lecturer in Lifelong Learning for Data Science and Computing at OUDCE. He has taught at the department since 2016 on a range of programming, software engineering, artificial intelligence and data science courses. He completed his PhD in Computer Science Education (CSEd) in 2020 and now applies his pedagogical research to the development of courses and contributes to the department’s AI Steering Group. He is also a Senior Fellow of the Higher Education Academy (SFHEA), an AdvanceHE certified External Examiner, and a Professional Member of the British Computing Society (MBCS).

"@davidjmalan, who has taught @CS50 every year since 2007, is on sabbatical, with computer science lecturer Henry H. Leitner taking over as the course changes its lecture format, assessments, and grading structure." thecrimson.com/article/2026/…

¡Hola, mundo! Estamos lanzando CS50x doblado al español. Las 12 clases, con temas que van desde Scratch hasta Estructuras de Datos, ya están disponibles totalmente dobladas al español. ¡Feliz aprendizaje! cs50.ly/es, made possible with lingopal.ai.

Learn why it’s worth investing in your own skills from @CS50’s own Carter Zenke.

How do you escape tutorial hell? @CS50’s own Carter Zenke bets it’s easier than it seems.

What lets C, Rust, and other languages achieve higher speeds than Python? @CS50’s own Brian Yu explains.

Find out why it’s good to learn coding as though AI didn’t exist from @CS50’s own Colton Ogden.

Ever wondered what P and NP problems are? @CS50’s own Brian Yu is here to explain.

@CS50’s own Carter Zenke weighs in on staying motivated when technology is moving faster than we can keep up.

Is learning to code still important? @CS50’s own Colton Ogden weighs in.
