I love these tiny explainers! Even if I already know what it's about, having a confirmation helps throughout reading.

understanding this stuff saves you hours when debugging memory leaks or weird segfaults.

most devs skip straight to valgrind without knowing what they're looking for. knowing where your stack ends and heap begins makes those tools actually useful instead of just noise.

"mmap, without the fog"

I don't know if this is just me being paranoid, but every time I see a phrase like this in an article I feel like it's co-written by an LLM and it makes me mad...

    The article does feel like Gemini when you ask it to explain you something in layman terms, but co-authored by chatgpt with nonsense like "without the fog".

Instruction pipelining and this is exactly why I wish we still have the time to go back to "it is exactly as it is", think the 6502 or any architecture that does not pretend/map/table/proxy/ringaway anything.

That, but a hell lot of it with fast interconnect!

... one can always dream.

    The article is essentially describing virtual memory (with enhancements) which predates the 6502 by a decade or so.

    I'm curious how this dream is superior to where we are? Yes, things are more complex. But it isn't like this complexity didn't buy us anything. Quite the contrary.

      Totally depends on who "us" and isn't. What problem is being solved etc. In the aggregate clearly the trade off has been beneficial to the most people. If what you want to do got traded, well you can still dream.
