Comment: Nearly 2 Million Lines of Code (Score 1) 160

uses nearly two million lines of computer code .... The system almost doubles the number of flights that can be tracked and displayed to controllers

Nearly two million lines, and almost double the capacity... If they bumped it up to an even two million I wonder if they could've completely doubled the number of the flights that could be tracked.

And what if they expanded it to four million lines of code, could they have quadrupled the number of flights that could be tracked?

And what if they made the code self-replicating? Could they have support an infinite number of flights?

But who drinks tap water?

Me. I drink lots of New York City tap water... At my office in Brooklyn I only drink tap water, just go to the kitchen sink, let it run for a minute, then fill up my cup. Everyone else drinks the bottled water we get, but to me it tastes like a plastic bottle.

At home in Manhattan, I keep a few bottles of water in the fridge and refill them from the tap...

I can't tell whether you're kidding

I'm not sure, either anymore... I carry my cell phone when I leave the apartment, but certainly not inside, where it just stays on my desk. But my wife, on the other hand, carries hers from room to room to room...

Other people I know won't ever let theirs out of arm's reach for fear of missing something....

Using your hourly billing rate as an opportunity cost only works if you would actually forgo that income if you spent that time doing something other than earning wages. Since most people shop outside of work hours there is no lost wages and so the opportunity cost is much smaller

I think of it as putting a value on my time. Even outside working hours, when I won't lose that income for doing other things, it's still about what my free time is worth. How much value do I put on spending my limited free time doing unpleasant tasks, and what's it worth to spend a little more money to avoid the tasks.

On a salary, the money keeps rolling in on a regular basis. If I squander a bit of it, I'll get more with the next paycheck. If I squander my time, it's gone for ever.

I used to ride bikes all the time as a kid, but that was in rural Oregon...

The last time I tried bicycling was in urban India and it was just too frightening trying to negotiate traffic. I was with an Indian friend who was comfortable enough (beyond being on a bicycle instead of a motorcycle) but he'd zip through intersections and I'd be left behind, not ready to run a red light, unsure whether to go to the left or the right of an oxcart and afraid of hitting pedestrians...

Now I live in NYC and I'm often tempted to try bicycling, but I'm not comfortable with the traffic. It's so much busier than rural Oregon.
