When are you truly forced to use UUID as part of the design?
...n 4 UUID, even if you're generating quite a few UUIDs per second.
Also, 2^64 * 16 is 256 exabytes. As in, you would need to store 256 exabytes worth of IDs before you had a 50% chance of an ID collision in a single application space.

Why do stacks typically grow downwards?
... written, so that it would know the actual RAM installed (e.g., a z80 with 64K address space didn't necessarily have 64K or RAM, in fact 64K would have been massive in my early days). Once it found the top actual address, it would set the stack pointer appropriately and could then start calling subr...
