Never assume any “small” feature is easy to define and/or to implement. A simple checkbox can contain a world of pain is a hard lesson in my career.

And the fun part is until you look closely at how it works you don't know which one you've got

Russia assumed time was on its side, but a new Ukrainian strategy is yielding surprising results.
