Justin Meiners writes about programming, math and game graphics, including a tutorial on writing a virtual machine and a hosted copy of SICP.
Commenters recommend his virtual machine tutorial for learning bitwise operations and link his pre-rendered backgrounds article and his SICP HTML copy.
I argue that (good) literate programming can make code literature. Your program is told as a sort of story and ought to contain background info, thought processes, and rationale for decisions. Additionally macros can be used to reuse code at build ('tangle') time that your underlying language may not otherwise support.
For example if I have some constants i need throughout a python program, I might put it in something like constant.py during normal programming, but if I were literate programming I could have a section called "Program constants" and dive into each one, referencing them with macros throughout the program. You do have to be careful because the macros can make debugging confusing since you are now working with two languages instead of 1.
You can also put stuff that is irrelevant to humans out of the way of the most important stuff.

Justin's GitHub states: "MIT just recently took down the book from their own site (why?!)"

It looks like MIT Press released a Javascript version of SICP that is for sale:

One fun way to get familiar with bitwise operations is writing a virtual machine, as it involves a lot of masking and shifting bits from instructions to extract relevant pieces (dare I say bits) of information. If anyone is interested in going this route, I recommend LC-3, as it's very straightforward.
