Coin Toss is a single-purpose package that will randomly return a 0 or 1. It comes with an executable, toss which will write the result of the flip as, again, a 0 or 1. Perfect when you want to randomly fail a build script step with a non-zero return value. Prank your friends and co-workers.
If you're new to Go, and especially Go on Windows, I've written about what I've learned so far.
You can download the source using go get. From the command line, run
> go get github.com/hyrmn/cointoss/cmd/toss
This will download the entire repository and place it within your %GOPATH%\src directory
Next, if you want, you can have Go compile the program and copy it to the %GOPATH%\bin directory
> go install github.com/hyrmn/cointoss/cmd/toss
Now you'll have an executable named toss (toss.exe on Windows).
> toss
This uses Golang's rand package. As such, it is not suitable for cryptographic applications. But, then, if you're using a random 0 or 1 with a 50/50 distribution over enough iterations, you're probably not thinking of cryptographic applications 😜
Ok, this isn't really a serious project. Although the fact that only returns a 0 or 1 to stdout does make it suitable to chain with other CLI tools.
I'm going to include a web server and Docker deployment target. Why? Because.
