Turning data into something visual helps humans make sense of things. Kai explains and shows an open source tool for tracking your research.

Language Models' Achilles heel: Rob Miles talks about "glitch" tokens, those mysterious words which, which result in gibberish when entered into some large language models.

Taking the theory of Deterministic Finite Automata and plugging it into Python with Professor Thorsten Altenkirch of the University of Nottingham.

AI moves quickly, this conversation was recorded March 3rd 2023. Microsoft have incorporated a large language model into the Bing search engine. Rob Miles discusses how it's been going.

Researchers stumbled upon a simple but worrying bug. Cropped images from Pixel phones contained a great deal of the original image in the cropped file. Drs Steve Bagley & Mike Pound explain.

An oldie but a goodie, Dr Mike Pound revisits the Log-Jam attack.

Professor Brailsford helped Adobe with PDF. His group helped move publishing forwards by publishing a journal about publishing using the actual processes the journal described!

Non deterministic finite state automata described and then shown in Python by Professor Thorsten Altenkirch

"Ethernet" was named because the inventor believed that the standard could transcend different types of media & 50 yrs on, we still use it! Dr Steve Bagley explains and demos the idea

The four underlying principles of Quantum. Part one of a series on Quantum Computing, Victor V. Albert is a Theoretical physicist at University of Maryland and NIST.

Continuing our look at the world of quantum, we're looking at the application of quantum technologies, from quantum cryptography to quantum computing. Victor V. Albert is a Theoretical physicist at University of Maryland and NIST.

Extracting a secret key by simply watching the flickering of an LED? Sounds implausible but that's what we're discussing with Dr Mike Pound! Author’s page on the attack: Video-Based Cryptanalysis

What's actually possible vs what's theoretically possible vs what's actually useful with quantum computing? Victor V. Albert of University of Maryland and NIST simplifies!

Coping with code to constantly count configurations of cubes can cause considerable consternation. Can Computerphile contributor Mike’s concoction continue calculating complete cube configurations or culminate in catastrophe?

How do we measure harm to improve the performance of Ai in the real world? Dr Hana Chockler is a Reader in Computer Science at King’s College London.

There's a lot of talk of image and text AI with large language models and image generators generating media (in both senses of the word) - but what about graphs? Dr David Kohan Marzagao specialises in Machine Learning for Graph-Structured Data and takes us through some simple examples.

At the heart of Bzip2 is the Burrows Wheeler Transform. Dr Steve Bagley (and a live studio audience) explains how & why it works.

Can you replicate millions of dollars of tech with a webcam and an arduino?| Not really, but you can get pretty close! Dr Alex Turner took to the motorways of Britain to prove a point!

Share part of a secret without knowing which part?| Dr Tim Muller explains how Oblivious Transfer works.

Programs aren't capable of generating true random numbers, so how can we? Are they even useful? Dr Valerio Giuffrida demonstrates how to get a true random number from most computers.

Legendary cyber-security expert Professor Gene Spafford joins us to try to define what cyber-security even is! "Spaf" as he's known, is a faculty member at Purdue University and now Honorary Professor at the University of Nottingham. Dr Spafford is a Fellow of the American Academy of Arts and Sciences, the Association for the Advancement of Science, the ACM, the IEEE, and the (ISC)2; a Distinguished Fellow of the ISSA; and a member of the Cyber Security Hall of Fame, the only person to ever hold all these distinctions.

Ahead of an upcoming Python implementation, Professor Thorsten Altenkirch goes through the details and definitions of Regular Expressions.
