> Say there's an article that teaches you how to build a custom embedded Linux, cross compile software to it, c internals, serial debugging in qemu with gdb/gdbserver, how to write a streaming parser in Haskell for Linux kernel calls, how to run Linux in the browser and use it from JavaScript etc. (all in the same article, with a common goal for all tasks). The article would come with a video walkthrough as well. You're describing a course, not an article. People do pay for courses. I don't think that many people will pay for an article that can be read in a few minutes.
