A quick test with strace on my machine shows that callocing and mallocing a 2GB buffer results in the exact same mmap system call for both. Neither use huge pages.

The pointer itself is const; not what it points to. bar -> const pointer to mutable array of ints *bar -> mutable array of ints And const pointers are dereferenced with * , not (* const), so the rule needs an exception f

License changes are not unheard of. Wine changed from the MIT license to LGPL without all of the developer's support.

There are definitely I/O side effects, but it looks like functions for mutating data structures (like set-cdr!) are intentionally unimplemented: https://github.com/aoh/owl-lisp/blob/master/scheme&#x2

The assembler and Makefile are x86 only. I'm not seeing support for other architectures.

std::array is not really comparable since its size is fixed at compile time. std::vector or std::list are more similar. The big advantage is creating copies. Copying a list or vector is O(n) in both time and memory, while this is O(1) in bo

The U.S. defence budget is ~$700 billion / year and the U.S. population is ~320 million. Gutting the entire defence budget would be worth just over $2000 / year per person. Not exactly enough for UBI.

I don't think robots change anything. Robots increase efficiency of human workers, they don't replace them entirely. Netflix and Redbox are highly automated, but they still have human workers; just fewer than Blockbuster did. Robo
