Advertisements The total possible no of unique git commit hash values are – 16^40, 16 possible hexadecimal digits and 40 total digits in the SHA value. This approximates to ~10^48 (more than that, but just an approximation). My question is – as the values are unique for commits, how are they not exhausted by now?… Read More How are the hash values in git not exhausted?
Advertisements void func() { std::future<int> fut = std::async(std::launch::async, []{ std::this_thread::sleep_for(std::chrono::seconds(10)); return 8; }); return; } Let’s say that I have such a function. An object fut of std::future<int> is initialized with a std::async job, which will return an integer in the future. But the fut will be immediately released after the function func returns. Is… Read More Can std::future cause coredump without get or wait

Advertisements I was making a Physics Engine in C++ when I noticed that when I replace: float absDistance = sqrt(vectorDistance.x * vectorDistance.x + vectorDistance.y * vectorDistance.y); With: float absDistance = abs(vectorDistance.x) + abs(vectorDistance.y) Different things happen. I’m using the library <cmath> I looked at a lot of stack exchanges but I couldn’t find anyone saying… Read More Why is abs(x)+abs(y) different from sqrt(x*x + y*y)
Advertisements Someone on this platform has already helped me with generating the following code: col,row = (100,1000) a = np.random.uniform(0,10,size=col*row).round(6).reshape(row,col) mask = (a*1e6+1).astype(int)%10<2 a[mask] += 2e-6 This code ensures that the last decimal is not a 0 or a 9. However, I would like to have no 0’s nor 9’s in all the decimals that… Read More Replace decimals in floating point numbers
