It’s something which comes up frequently on GCSE papers. This article discusses done of the most well known operating systems and what they provide. Most of it feeds in nicely with …. Read More
Click bait headline, but interesting look at distributed computing. It’s been going on for years. I remember a similar one that was searching for aliens, literally. It was essentially helping some of the science projects that were scanning space for life markers. It was very sci fi, back then we lived in the future.
Interesting video from Tom Scott which covers various things. In a broader sense, ideology. In specifics, sharing data between web servers/services. In terms of specifications, A-Level interfaces (not the interface between human and machine, but the interface between one system and another). It’s a good watch, and an essential watch for A-level students.
Matt Parker does some awesome maths stuff, particularly his spreadsheet standup routine which is an excellent look at how images are stored and displayed. This is an interesting puzzle, and one that can be modelled in Python….your task, is to model it in Python! Give it a go and I’ll do a couple of videos …. Read More
Have you every got onto a train and given a heavy sigh as you realise there’s still 9,223,372,036,854,775,798 stops until you reach home? It seems someone made a mistake. This video goes nicely into how this mistake could have happened and looks at some of the binary etc behind it. Worth a watch for years …. Read More
This video is explaining why RAM prices are….volatile (see what I did there?). Whilst it’s interesting in itself, it’s also interesting to note how widely used RAM is, how many different devices use it. The amount CPU chips for example are used is a lot less because there’s a lot more specific CPUs then there …. Read More
https://medium.com/@james_aka_yale/the-4-layer-internet-model-network-engineers-need-to-know-e78432614a4f GCSE students (and A-Level students) will be familiar with the network stack…well…they’ll know it’s something they should know. It is however something which people are often fuzzy on. This article explains it nicely and talks about TCP and UDP and how it fits within the stack. Don’t worry about the OSI model, that’s something …. Read More
https://hackernoon.com/a-hacker-intercepted-your-wifi-traffic-stole-your-contacts-passwords-financial-data-heres-how-4fc0df9ff152 This article goes into some technical details, but it’s a good example of how attacks can be made, in particular pharming attacks. Do not try this at home….actually…that’s the only place you CAN try it, provided you’ve got everyone’s permission. You to a parent> “Can I instruct the link layer to not discard packets …. Read More
Excuse the clickbait title, it isn’t to mean ANY game is good for learning, just that there are principles in games that we can use in learning to help you learn better. In Computing we want students to try things. In Python, Flowol, Kodu, Spreadsheets, Audacity and more, we want you to try things. If …. Read More
