"videos that go a bit beyond 'grade school level' learning." Well said, KZitem has a lot of educational content targeted for a 13 year old to understand or a sophisticated group debate or a straight up University lecture. - The 1st is fair but cuts out so many people who know a few things about the world. - Group debate is great for getting opinions and seeing into what other world leading experts think but isn't overly educational and can often go off topic for small periods. -University lectures are great if you're waist deep in a certain topic and have some advanced questions Videos like these provide the bridge to understanding those university lectures a bit better and work well for an informed adult who hasn't got a phd in said topic.

It doesn't really happen these days. There is a mapping layer (paging) between what the program sees as a RAM address and what actually is a RAM address. So what happens is that in the page table, there is a theoretical "page" of memory created called the "guard page". Should the stack try to expand into that, it will generate an interrupt which the OS will handle causing it to map more memory into the stack. Or blue-screen and die. Depends.

CISC was mainstream way before the x86 architecture was invented. The 4004 x86 fore-runner was based on DEC designs which were then all CISC. The term CISC was only coined when RISC architectures came along when memory started to get cheaper. The term only came about to contrast with the new RISC, which was generally faster and more flexible than CISC. The underlying architecture of a lot of CISC processors is actually RISC with the microcode implementing the CISC instruction set.

Not only that; but it was such a smooth gradient. The ALU was defined in concept, before it was implemented in hardware, before there were integrated circuit full adders, then there were IC ALUs, then there were microcomputers built of many ICs, before there was a single chip microprocessor. The microprosessor didn’t just appear out of nothing from a genius at intel; it was bloody obvious that integrated circuits could eventually integrate registers, decoders, ALUs etc into a single chip CPU. Every example I can think of looks not like a step function were something just appeared out of nowhere, but as a very smooth and gradual development with some false starts (too early, not viable yet) and very often slow diffusion from mainframe or flight simulator hardware to minicomputer or professional industry and eventually to home users.

Stack SS:[SP] or SS:[ESP] actually hangs from top. When you push a (d)word to stack, you push it to the bottom of the stack, and stack pointer decreases by 2 or 4 towards bottom (SP decreases first then data is pushed to the address where SP points to). Because of this stacks are (or were) voulnerable to "smash the stack" attacks, where subroutine parameters were first pushed to the stack, then return EIP was pushed to stack, then subroutine executes and creates local subroutine variables area that is phisically located beneath (before) return EIP, and thus if data written to local variables is not checked for length, it can actually overwrite all other local data, return EIP address etc and upon RET execution force CPU to jump to arbitrary data address where injected code resides. In this way you can gain full controll over CPU remotely just by serving your code disguised as data to a buggy routine that causes stack overflow. So, stack hangs from the ceiling down.

X64 is a CISC instruction set, but ever since the pentium pro the CPU itself is RISC. Instructions are decoded into multiple RISC-like micro-ops (same instruction size, simple instructions) and then handled exactly as if they were RISC. The CISC frontend adds latency, and that’s bad, but it also effectively functions as memory compression. You would have needed more bandwidth to read the instructions for a RISC programme.
