Using Chrome to calculate the square root of e
It maybe extremely obvious for most of the experienced HNers but I accidentally found it and I think it is quite neat.
It is just the Google Chrome Javascript console: It is three clicks away: Wrench->Tools->Javascript Console
Sometimes you need to calculate something simple and you are not online or you do not have other more powerful tools. Just by:
>Math.sqrt(Math.E) ; square root of e 1.6487212707001282
Of course somebody can do much more things with that(it is the Javascript Console after all).
I found it neat and I wanted to share. I apologize to those that find it obvious.
