I have no formal training as a programmer. I have never taken a class. I am simply reading what I can find, trying things out, experimenting, ad asking questions.
I am familiar with MAC OS, Windows 7, and a few different distributions of Linux. I have installed Arch Linux (KDE) to my '09 MacBook, Fedora 25 Linux (GNOME) on my Lenovo x201, and Sierra on my '13 Macbook Air.
I mostly edit in Visual Studio Code or Nano. Limited experience with: HTML, css, java, php, Bash, and C.
