I'm looking for books on technical topics that don't contain a lot of heavy calculations or math that requires extensive outside research. I’m fine with a few equations here and there, but I’d like something I can read while at work or on the bus.

I am primarily interested in Electrical Engineering (any field), as well as Computer Science. However, if you know of any books in other engineering fields that are a good read, please share them!

Thank you in advance.

Why do i have hole-to-hole clearance here although I checked the "Ignore pad to pad clearance inside a footprint" in the rules?

in the link below:
https://fedevel.com/forum/altium-designer/17353-via-in-pad-and-drc-issues

someone faced the same issue as me and he solved it by just changing the vias on the perimeter to tht-pads + assigned them the same designator (which I did) but it didn't solve the problem I'm still getting DRC warnings.

On their website they have two clearance rules (last picture), which one should I follow?
