Today I realized that logical-and is just a fold-right operation which accumulates boolean values, and that you can nest arbitrarily complex, recursive logical structures inside it. SICP is fucking mind-bending. There is something incredibly satisfying about discovering these computational principles which seem baked into not just computers but the structure and fabric of reality itself. This book is like a drug.

Which function is faster?

#define SIZE 10000000

float Foo(const float* a, const float* b) {
float sum = 0;
for (int i = 0; i < SIZE; i++) {
sum += a[i] * b[i];
}
return sum;
}

float Bar(const float* a, const float* b) {
float* c = new float[SIZE];
float sum = 0;

for (int i = 0; i < SIZE; i++) {
c[i] = a[i] * b[i];
}
for (int i = 0; i < SIZE; i++) {
sum += c[i];
}
delete[] c;
return sum;
}
