### AI overview

This tutorial explains reservoir sampling for selecting an item uniformly at random from a data stream whose size is unknown or too large to store in memory. Its Python algorithm keeps one item and replaces it at step k with probability 1/k, with an induction-based proof of uniform selection.

### Source excerpt

Problem: Given a data stream of unknown size $ n$, pick an entry uniformly at random. That is, each entry has a $ 1/n$ chance of being chosen. Solution: (in Python) import random def reservoirSample(stream): for k,x in enumerate(stream, start=1): if random.random() < 1.0 / k: chosen = x return chosen Discussion: This is one of many techniques used to solve a problem called reservoir sampling. We often encounter data sets that we'd like to sample elements from at random.

### AI overview

This article explains Intel's RDRAND instruction, which uses an on-processor entropy source and AES conditioning to produce hardware-generated random numbers. It also describes checking the carry flag because RDRAND may temporarily return no data when demand exceeds hardware supply.

### Source excerpt

Hardware entropy: RDRAND This is the third blog post on machine instructions: This time I've noticed instruction. According to Wikipedia is: ... a random number generator that is compliant with security and cryptographic standards such as NIST SP800-90, FIPS 140-2, and ANSI X9.82. The generator uses an on-processor entropy source, which passes the randomly generated bits to an AES (in CBC-MAC mode) conditioner to distill the entropy into non-deterministic random numbers. Sounds good.
