Biometric authentication is on the rise. Fingerprint sensors, iris recognition in airports, and face unlock on phones. Does it work if you just put a picture of the owner in front of the camera? It shouldn’t. Here’s a look at the technology hidden in a Pixel 4 which maps your face in 3D with an …. Read More
Interesting video about some vulnerabilities. What GCSE students need to take from it is the carving up on the RAM for different programs, that’s part of the operating systems job in the system software lessons.
https://www.bbc.co.uk/news/technology-49826161 I was asked about creating a new currency, it is indeed possible but not easy. It starts touching on the essence of what money is.

Matt Parker made a computer out of dominoes. Yup. It’s really cool, he constructed logic gates (which he breaks down in a separate video) out of dominoes. It’s a simple calculator so takes two numbers and adds them together, but it’s impressive to see how it’s working.
This is a fascinating series that creates a computer from a single chip. It gets very deep on the electronics very quickly. Proceed with care.
Customer details were hacked from Moonpig, this is a breakdown of what happened, but also important thoughts about what should be done when someone finds a vulnerability.
These are the logic gates that we need for AQA GCSE 2019-2021. Next year will add XOR, but for now, these are all. My magnificent year 10 class take the credit for the graphic idea for the NOT gate, I take the credit for the others myself. Hopefully they’ll help you remember which one is …. Read More
If you’ve done lesson 6 of the understanding computers module in year 8, you may have seen the history of the computer include the typewriter which is where the weird order of letters on your current keyboard comes from. If you’ve wondered why they’re placed in this weird order or if there’s a better way, …. Read More
Right, break statements and why they’re bad. Generally it’s indicating you’ve got a problem with the flow of your program and you may need to restructure. Imagine the following that hunts for a number, it’s an odd program, but it’s an illustration. # x = some number you’re hunting forx = 56for i in range(100): …. Read More
