Maybe its just my domain, but most perf problems I've seen relate to architechture and infrastrucutre decisions, and not really code or algorithms. Especially the "microservice" mantra, splitting out simple functions into co

I used to think this is a good idea. However, the reality is when you join the military it should be reasonable assumption you are going to be sent somewhere to actually fight at some point. My proposed alternative would be, when you sign

I'm not a libertarian but I think they have a point here - conscription is tantamount to slave labor. The fact that it was accepted by societies for hundreds of years doesn't make it any less so.

The usual understanding of "interpreter" in a CS context is program that executes source code directly without a compilation step. However the binary that translates an intermediate bytecode to native machine code is at least som

This is the case only if the new interpreter does not simply include the layer that the old interpreter has for translating bytecode to native instructions. Once you have that, you can simply bootstrap any new interpreters from previous on

I guess it depends on where you went. I was a CS student at Virginia Tech in the late 90s. The CS department wasn't even in the engineering school. We did have to take computer architechture which was the only courses other than mat

And it ... works? Use C, C++ or Fortran for the heavy lifting, and Python for UI/business logic/non-high perf stuff for rapid app development.
