I liked the courses at freecodecamp.org a lot too.
Rpi's are a so much fun. They are great little computers and so much fun. I think I've got a PI3 running my Twitter bot and the news aggregator on my website. They're handy for so much.
Now that winters here I'll be doing a lot more coding again. I generally screw off all summer and code all winter through the cold months! Mainly HTML,CSS and I think I'm focusing on JavaScript and NodeJS all through this winter.
Enjoy the new Pi!
Thank you it is not easy getting back into the set up of a computer,and learning a new operating system, and finding where to find things, and people think Hive is hard.
Yeah, it takes time for sure. It comes to you with time though. I made the move to linux many years ago and it's my favorite operating system now. Once you start using it daily it just becomes second nature like Windows or any other OS. Eventually your comfort level grows as you become more knowledgeable. Good luck :)
