    Amazing presentation! I wonder how a software engineer can think of such visual explanations! Hats off.

    Amazing. I got a bit stuck at "buffer yourself". I saw this presentation shortly after it was uploaded in 2019 and since then it's become my pet peeve in code reviews as well as sortof catchphrase. "Go buffer yourself".

    Great talk man, instead of just showing slides and talking you are showing all the nuts and bolts that makes the program what it is.

    Great talk, especially switching to tracing when cpu profiling gave no clue.

    I did not get it fully, why on the first part, when Dave moves the buffer declaration to file scope, that avoids that escaping of the buffer to the heap. Why did it escape to the heap? I watched his explanation over and over, but it's still not 100% for me.

      My understanding is that slices work as pointers to a subsection of the underlying array. Because the declaration is only invoked once, there are no memory allocation requests and therefore you are recycling the same memory byte as opposed to asking the OS to give you a new piece of the stack every time you call the function.

    • @sebas11tian
      @sebas11tian 3 роки тому

      The compiler, therefore knows what will happen to the array in the stack once the function is closed and therefore it can declare that keeping it in the stack frame is safe and does not require going off to the heap.

    Nice talk. It's kind of infuriating that go doesn't just inline readByte and avoid the heap allocation, though.

    What were the 3 different profiling techniques ?
    - pprof
    - trace
    - ??

    When you started talking about thousands of cores and calculating each row or pixel on a core - I thought you were going to dive into GPU programming 🤣
