You keep posting the same obviously incorrect expression. And you keep posting it using ##LaTeX## math notation which is completely inappropriate. The expression is obviously incorrect because the first node of the diagram is clearly R* not R+. Studying from what source? Please provide a...

Firstly, ##LaTeX## is not helpful for posting regular expressions; for instance it makes + look like a binary operator. Neither of the regular expressions you post correctly describe the diagram: @SSequence has posted a string that is incorrectly rejected by the second expression (R+SU*T)SU*...

Do you have a question?

Packets are discarded if more than ## b ## packets are generated in the first slot. Why do you think that the number generated is limited to ## b ##? Note also that it is unclear whether the condition "Assuming that the buffer is empty at the beginning of the first slot" in part (a) also...

Neither: you don't want the secondary device to be doing any routing, you want to use it as a switch. Google the brand of router and "use as wifi extender" for specific help.

I also For C++ code Doxygen is the standard. If you want to add some diagrams giving an overview that's fine, but only once you have documented every public property and method. If you use a relational database you should document that too.

Can you get the boards working through the Arduino IDE? What command are you using for AVRDUDE?

But any problems with that can be solved by storing values as cents and using integer arithmetic. This is what is done in practice in all the financial software with which I am familiar (with adaptations for other currencies to cater for example for denominations of 0.5 cent where these exist)...

I don't think that is true any more, at least not in the UK or Europe, but I'd be interested in any reference.

You can read what MS chose to make public about this series of attacks at https://www.microsoft.com/en-us/security/blog/2021/12/15/a-report-on-nobeliums-unprecedented-nation-state-attack/

My opinion is not printable within forum rules. Whoever has published this should have their funding withdrawn.

As luck would have it, MS have screwed up the latest VS code Windows release yesterday (auto-updated for most people): the 'Open with code' option is removed from the Explorer 'right click' context menu - see this issue. To fix this, download and install the previous, June 2025, version 102...

Yes, I am and so are 75% of the rest of the developer community. In 2025 learning either Vim or EMACS (or Eclipse for that matter) is a waste of time and effort for someone starting out in development: there are MUCH more important challenges to cope with. Use VS Code with the appropriate...

So here is the examiners' report for this question: "It was good to see a number of students having some understanding of similar shapes and awarding 2 marks for a value of x =2 correctly found wasn’t uncommon. Almost no students were then able to deduce the second assumption that could be made...
