• Are Vectorized Random Number Generators Actually Useful? - Aug 28, 2018.
  
  I reported that you can multiply the speed of common (fast) random number generators such as PCG and xorshift128+ by a factor of three or four by vectorizing them using SIMD instructions. Is this actually useful in practice?

• The Surprising Complexity of Randomness - Jun 15, 2017.
  
  The reason we have pseudorandom numbers is because generating true random numbers using a computer is difficult. Computers, by design, are excellent at taking a set of instructions and carrying them out in the exact same way, every single time.
