How unique is UUID?
...ely generate a batch of 16,384 UUIDs within the span of a single "tick" in order to overflow the sequence number. I have seen this happen with an implementation that relied, naively, on a clock source that (1) had μs-level granularity, and (2) was not guaranteed to be monotonic (system clocks are ...

...erface.
IList<T> is essentially an ICollection<T> with random order-based access.
In this case you should decide whether or not your results require list semantics such as order based indexing (then use IList<T>) or whether you just need to return an unordered "bag" of results (t...
Why prefer two's complement over sign-and-magnitude for signed numbers?
I'm just curious if there's a reason why in order to represent -1 in binary, two's complement is used: flipping the bits and adding 1?

The lowest guarantee offered is basic, but then, the ordering of each instruction makes the whole function "none", because if 3. throws, x will leak.
The first thing to do would be to make the function "basic", that is putting x in a smart pointer until it is safely owned by th...
