I spent five hours in a code review. And forty five minutes explaining the difference between an "index" and a "key" to someone who'd presumably been using them for six months...
So...what's the difference between an index and a key?
Just kidding. 'Sides, I'm assuming it's what you'd think: the index is kind of a list of contents and the key is...well...a list of what = what, kinda.
At least today I can officially say I've lost four pounds since the beginning of the year. Less than a pound a week, so I'm not speedy, but it's something. If I don't welch out, by late spring I might actually finally get to the goal I tried for three years ago.
