I don't have any questions, but I just started reading it a few days ago, and I'm re-implementing it in Nim (which is an interesting experience). One issue I ran into right away was that my code from step 1 was segfaulting, and the issue was that I accidentally called `mprotect` before copying the memory into the buffer. Easy mistake to make, so you might want to add a warning for people who aren't just copy-pasting the code.

Excellent! I'm so happy you're following along in another language. If you're developing in the open, can I link to it somewhere on the series?

It's a good point and I'll try and remember to add a notice about order being important later.

Once I'm ready I'm planning on throwing it up on github for sure. I'll make a note to send you an email with it :)

Awesome. Looking forward to it.
