Give this a try: Link
ANGLE(X,Y)
Arctangent of Y/X, in proper quadrant. That is, returns the angle theta formed between the x-axis and the point (x,y), such that -pi < theta <= pi.

Thanks very much for that - wish I had two days ago! It will help out in understanding some other obscure stuff as well, where I have forgotten what I wrote it for nearly 40 years ago! 
In fact it is the same as ArcTan2 with the input reversed. I had used it in a user defined function to turn the angle of a line defined by x and y coordinates into a bearing between 0 and 360 degrees.
Anyway, thanks!

In the recent google doodle video, Michael Collins says that wherever he went after the returning from the Apollo 11 mission, people said to him "We did it!".
Made me emotional.

I saw that yesterday, and did did the same thing.

for any rule in the grammar, compute the viable prefixes for that rule and a given k value.
gosh, no big deal.
note: sometimes this results in ridiculous amounts of data if you're doing it right, due to the exponential properties of permutation.
oh.
oh yeah, and you forgot to keep going after the end of a rule, because you need to trace it through whatever can follow it's left hand side in the grammar.
oh.
i have a headache in my eye.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

I stumbled upon this product which is a bluetooth enabled set of 5 rings which contain accelerometers and allow you to type messages by tapping your fingers.
You only get one "hands-worth" and you have to train yourself to use them. An interesting and innovative idea though.

I question that you'd be able to actually type much at all though from this review:
reviewer said: Good first generation, but I think it needs a couple generations of updates.

This product is a wonderful idea, but needs significant refinement before it will be seriously useful. First, I spent a while learning the keyboard, which was pretty neat. The design and placement of most of the keys was pretty easy to pick up. But things started getting wonky the moment I tried to type more than a dozen words a minute - not that I didn't know which fingers to tap, but Tap would regularly mis-read my taps as other characters. Particularly when the tap requires two fingers, such as the middle finger and pinky to type "z" would often also register the ring finger as tapped as well (in fact, typing those two fingers by themselves is a challenge all of its own that took time to overcome).

Well I type one-handed anyway.

Interesting. Is that just what you became accustomed to? I find a lot of people are hunter-peckers even after typing for 10 years. I learned to touch type on a typewriter and then on a computer game on the C64 and glad I did.
|
|
|
|

I'm no hunter-pecker, I know where the keys are and I use all five digits on that one hand, but writing software isn't the same as writing prose, so there's no reason to type the same way.

Many years ago (more than ten, anyway) I was involved in a project that projected a keyboard on your desk and a vision system was used to detect and register keystrokes on it. We got our part of it to work, mostly, but it was scuttled in the end. The most interesting thing was a few years ago I saw a SF movie where that prototype was used in a science-fiction movie. That is, as far as I know it was the same prototype because everything about it exactly matched the one we did.
Maybe today, with our vastly improved AI and vision systems, it could be to work more reliably. That's what killed it originally - the error rate was way too high. I think that was a better idea than this one. This takes too much effort in my opinion. Plus, you can't just walk up to a system and start typing. You have to put on the rings first.

Yes, very much like that.

Really interesting story. Thanks for sharing that. I believe their might be some of those projected types for sale too, but I don't think anyone has every gotten them to work well (as you said, too many errors).
And I agree, if they could get that working it would be much cooler than this ring idea.
