You can't always give all a function's inputs at the same time. Professor Graham Hutton explains about ... Moving on from crude error correction to more sophisticated methods, Professor Brailsford demostrates using the ISBN ' Enigma is known as the WWII cipher, but how does it hold up in 2021? Dr Mike Pound implemented it and shows how it stacks up ...

Summing up why Hamming's error correcting Knuth talked about "Literate Programming" over forty years ago, but what does it mean to have Brian Kernighan, the man who wrote the definitive Encoding recursion in the Lambda calculus, one of Professor Graham Hutton's favourite functions. Lambda Calculus: ... Play around with one of the first Von Neumann machines (well, in simulation!) Professor Brailsford shows us what EDSAC was ... Hitler's High Command didn't use Enigma, they used a faster system called Lorenz, but when Allied forces first encountered it, ...

Drawing windows and responding to events - what's going on 'under the hood' in your GUI? Dr Steve Bagley. Thanks to David ... Surely decimal numbers are easier to understand than binary? So why don't computers use them? Professor Brailsford explains ...
