Principles of Adult Behavior

Be patient. No matter what.
Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
Never assume the motives of others are, to them, less noble than yours are to you.
Expand your sense of the possible.
Don’t trouble yourself with matters you truly cannot change.
Expect no more of anyone than you can deliver yourself.
Tolerate ambiguity.
Laugh at yourself frequently.

	// it provides an implementation of ReLU without branching.
	// the core idea of branchless-ReLU is the following.
	// 1. first, bitwise-and with 0 bits everytime returns 0 bits. but bitwise-and
	// with 1 bits returns the original argument kept intact.
	// 0000 & 1010 == 0000, 1111 & 1010 == 1010
	// 2. second, we can make 0 bits or 1 bits depending on the sign bit by applying
	// right arithmetic shift 31 times.
	// 1000 >> 31 == 1111, 0110 >> 31 == 0000
