Computerphile — transcripts.

1Haptic Rendering - ComputerphileSo we are going to talk about computer haptics today. Uh and I will give you an introduction of what haptics means. >> Okay. So I'm thinking of things like force feedback on a… 2The "Trick" that Compilers Use for Long Division - ComputerphileLong division was something that I never really got to grips with as a kid. It was like a torture, right? It was one of these long and painful things. >> It's been a while. Yeah… 3Oversampling Data (Explained with Audio) - ComputerphileRight. So, in the last episode we um discussed saturation which creates harmonics which are higher frequencies from a low harmonic which is all very well and good. Let's say… 4Fuzzing Programs to Find Bugs - ComputerphileI thought today we could have a chat about randomized testing, also known as fuzzing, which is a really effective technique for finding bugs in software. Where fuzzing began is… 5Original Hello World in "B" Programming Language - ComputerphileC is one of the best known uh programming languages probably became famous due to Unix. But B is sort of an obscure historic detail that people don't really know about and that is… 6Cyclic Redundancy Check (CRC) - ComputerphilePreviously, we've talked about the idea of how these computers are communicating. We did the clapping thing and I got it horrendously wrong. Where can we go from there? >> Well… 7Post Quantum Cryptography - ComputerphileIt's time to panic, Sean. We need to implement postquantum. >> Postquantum. >> Postquantum algorithms, right? We should all panic, right? >> This has nothing to do with the… 8Temporal Networks, Where Page Rank meets Lord of the Rings - ComputerphileIf I say to a computer file audience network, probably their minds are going to go to Wi-Fi and Ethernet or whatever. But there's another way to interpret network. What a… 9Vector Search with LLMs - ComputerphileI thought we'd take a look at vector search, which is one of the techniques used in modern chat systems to find data and use that data when answering questions. Right? So, we know… 10Human Readable Code - ComputerphileI thought what we'd talk about today is like programming, but we're instead of just trying to get our program to function correctly, we're really going to concentrate on making it… 11Coding a Guitar Sound in C - Computerphilecompletely unprocessed, nothing going on at all. And then seven lines of C. So what is that? What's going on there? That is what some people call saturation and other people call… 12Finding Hardware Bugs - ComputerphileWhat uh my research team and I have been most interested in in the last few years is trying to make EDA tools more reliable. So by EDA tools I mean these are the the tools that uh… 13Why Multi-Threaded Code Can Sometimes Misbehave (Weak Memory Concurrency) - ComputerphileToday, we're going to look at something called weak memory concurrency or weak memory models in general, which is to say, how do you describe the behavior of >> [snorts] >>… 14Bad Bot Problem - ComputerphileI'm not sure if you've been following the news, um, but there's lots of talk about bots, specifically bots on social media, spreading disinformation. Now, Imperver released their… 15Hacking on the PDP1 Raspberry Pi Emulator - ComputerphileFirst we will look a little bit into the history of these machines and uh we uh we use the PDP1 here as sort of our central uh starting point. The PDP1 um designed in like the 8…
