There’s a lot of noise about how “Joe Biden’s government wants you to move away from using C++”. This is as a result of the US government releasing a report, Back to the building blocks: A path toward secure and measurable software which suggests: Uncle Sam says "no!" “Memory safety vulnerabilities are a class of vulnerability affecting how memory can be accessed, written, allocated, or deallocated in unintended ways. Experts have identified a few programming languages that both lack traits associated with memory safety and also have high proliferation across critical systems, such as C and C++.

When your machine has multiple NUMA nodes it’s often useful to restrict a process to using just one for performance reasons. It’s sometimes hard to fully utilize multiple NUMA nodes and, if you get it wrong, it can cost in performance as the nodes need to keep their caches consistent and potentially access memory over a slower link than the memory that is closer to the node, these things can be relatively expensive.
