Don't get too impressed here by finance. Almost everything we're talking about here Linux Kernel Developments, SolarFlare (or Mellonx), core isolation (cpu set) was invented elsewhere. Finance merely buys it; it's a great client of all this tech. The only vaguely created-in-finance thing he/she references but then not even by name is https://martinfowler.com/articles/lmax.html https://martinfowler.com/articles/lmax.html which comes from ring buffers coming from CS EE networking itself.
