I learned of Raspberry Pi for the first time from John Walker a few weeks ago, with his announcement of the debut of Pi 4. As they are in great demand, it took nearly 2 weeks to get a hold of one with 4Gb RAM. I recall John advising to always get as much RAM as possible – I did so.
I needed a small monitor and researched them thoroughly. There are many, many choices. Since I am old and have tired eyes, I opted for a 20 inch screen. I bought a Sceptre with 1600 X 900 resolution. It isn’t IPS, but cost only $66. From the PiShop, I also got the wireless keyboard & mouse as well as Raspbian OS on a 32MG flash card. It started easily and runs flawlessly. My only addition was to tack a book light onto the keyboard in order to illuminate the keys, which have blue letters/numbers on black surface, i.e. very difficult to see without direct light. What do you want for $19.95?
In sum, I have a moderately powerful desktop for a total cost of $180. My main purpose in buying this is to learn more about how computers work – stuff like shells, kernels, BIOS, and more. I think that means I want to learn computer architecture and I also want to overcome my phobia of the command line in terminal mode. I apologize for the poor photo of my apparatus. Think of it as exemplary of my computer skills.
I have found many courses and/or books on the web. They are legion. I would much appreciate any advice as to what would be the best resource for a beginner like me.
