Inspired by [this tweet](https://twitter.com/laserallan/status/1159571592332087296).

Just call `go geiger.Count()` at the top of your `main` function. Don't worry, if

you start tasting metal, you're probably just delusional.

This package is in a pretty unpolished state. ~~First of all, it emits a constant

tone, not a series of clicks like a real Geiger counter, because I couldn't

figure out how to get the `beep` package to click the way I wanted.~~ (EDIT: [fixed, thanks @klauspost!](https://github.com/lukechampine/geiger/pull/1)) Second, the

package itself incurs a non-zero number of allocations per second (~100 on

MacOS, presumably different on other platforms) which throws off the reading.

Third, it's completely unconfigurable: you can't adjust the "sensitivity," and

you can only measure the number of objects allocated per second (as opposed to,

e.g., the number of *bytes* allocated per second).

Still, I think the general idea of "use sound to alert the programmer that

they're doing something stupid" has merit. If enough people agree, maybe we can

work together to refine it into an actually useful tool.

### Troubleshooting

This package uses [beep](https://github.com/faiface/beep) to play audio. If you

can't hear anything, please check the `beep` issue tracker (and open issues there,

if necessary) rather than on this repo. I know basically nothing about audio

interfaces, so I'm not going to be able to help you!
