Series author here. To respond to some of the comments...<p>Making it interactive with a repl would be great, I agree. I've thought about going down that route a few times in the past, but it's then something new to maintain forever. Text and pseudocode will last a long time without touching it.<p>Thanks for the contents on the Youtube channel. The reason I stopped was because it takes a lot of effort to make those things. And I never was able to successfully monetize them. I've made videos on some other platforms and made good money from them. I just don't have the time to sink into that now for nothing in return.<p>As for needing a better sales pitch, etc. heh, yeah. This is just a labor of love. It'll go up there and stay up there for many years hopefully. If people find it and get something out of it, I'm happy. I don't expect to make a cent out of it. I'm just passionate about writing and teaching. And I find I learn a lot more when I try to teach.
