I wrote the following C program: #include "stdio.h" __declspec(noinline) void DivideTest(int num, int denom) { int quo = num / denom; int rem = num % denom; printf("Quotient: %dnRemainder: %dn", quo, rem); } int main(int argc, char* argv[]) { //Use…
I stumbled upon a failing unit-test, that involves converting doubles to integers. The actual number that is converted is 1.234 * 1000., and the code basically boils down to: #include <iostream> #include <cstdint> int64_t deltatime(double numSeconds) { return (int64_t) (numSeconds…
I'm coding in nasm, and I don't get what is going on. The Linux distro is an Ubuntu 16 64bits, but the NASM is operating in 32bits. Expected output --> "Number is: 2" Actual output --> "number is: 134520868" Code:…

I am getting this error deterministically and immediately every time I run the code below. I am trying to use libcurl that I have built from source using nmap and using the recommended procedure and interestingly enough, I am able…
Description I created a sample to study the TLB access/misses statistics. Sample writes 1 to every 4096-th element of the array. Array has 10'000 * 4096 bytes. I expect to see 10'000 TLB stores only, but generated assembly loads beginning…

There is a recent publication at nature.com, Faster sorting algorithms discovered using deep reinforcement learning, where it talks about AlphaDev discovering a faster sorting algorithm. This caught my interest, and I've been trying to understand the discovery. Other articles about…

I was taking a look at this Github project: https://github.com/LloydLabs/delete-self-poc This project uses the SetFileInformationByHandle API (https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-setfileinformationbyhandle) in a somewhat creative way to allow the deletion from disk of a locked file. I am attempting to implement this as part…
