I've published eight novels. It's hard to earn money on fiction, unless you're good at marketing and you're writing a series in a genre that has a lot of binge readers (like romance, mystery, thriller). I do it mainly to satisfy an itch. I get an idea, and I want to get it out on paper. Non-fiction is easier to sell, if it provides value. You can charge higher prices for programming books than for mysteries, and people will pay because the knowledge they gain from the book will be worth the money. If your goal is to earn money from writing, please know that even if you produce excellent work, marketing is key. Identify your audience and find ways to connect to them. Have at least a minimal marketing plan in place before you publish.

That guy had a (very) minimal marketing plan, and it worked out pretty well for a first book.
