How do I use arrays in C++?
...uld simply provide x as the first argument. That is a little too terse for my taste, and it also makes template argument deduction a bit harder for the compiler, because in that case the first argument is an array but the second argument is a pointer. (Again, array-to-pointer decay kicks in.)

What is a monad?
...nced and that IO operations cannot "leak" to pure functions.
Summing up
In my subjective opinion, the monad pattern is only really worthwhile in a language which have some built-in support for the pattern. Otherwise it just leads to overly convoluted code. But Haskell (and some other languages) have...
When to use volatile with multi threading?

When I say load, I mean an asm instruction that accesses memory. That's what a ...

- add_per_worktree_entries_to_dir() is updated to make sure ref listing
look at per-worktree refs/rewritten/ instead of per-re...

What is a correct mime type for docx, pptx etc?
