Well, since ya asked all nice-like …
I mainly be keepin’ my code in Github repos. I go into more detail about the projects themselves in a separate page.
Public
Here is my public Github account.
Huzzah!
Bear ye witness to recent experiments, Wikis, contributions, Gists,
plus ancient Ruby gems that I haven’t touched in years!
Private
Honestly though, I keep most of my code private.
I host my own Git repo in the AWS cloud.
Because I am old school 
.
An SSH Key can be issued upon request.
Open Source
Sigh 
I am not by any means a regular Open-Source Contributor.
However … if I use something, and it’s broken, and I can fix it, I’ll create an Issue and address it with a PR. I’ll even gladly fill in the Test Suite. Heck, sometimes I’ve actually introduced the Test Suite …
Considering how much benefit I’ve gotten from using Open Source projects over the years, I really should contribute more.
