It’s getting more funny if you look at his GitHub account. https://github.com/lemire https://github.com/lemire “His research is focused on software performance

  Looking at one of the papers he has published "Many applications use sequences of n consecutive symbols (n-grams). Hashing these n-grams can be a performance bottleneck. For more speed, recursive hash families compute hash values by updating previous values. We prove that recursive hash families cannot be more than pairwise independent. While hashing by irreducible polynomials is pairwise independent, our implementations either run in time O(n) or use an exponential amount of memory. As a more scalable alternative, we make hashing by cyclic polynomials pairwise independent by ignoring n-1 bits. Experimentally, we show that hashing by cyclic polynomials is is twice as fast as hashing by irreducible polynomials. We also show that randomized Karp-Rabin hash families are not pairwise independent." I think he is working on the fundamental science of computer science. People like him are the reason we have nice things like web servers. That doesn't mean they know the specifics of Apache or Wordpres.
