I've had this in my bookmarks for awhile, intending to work through it. I think I can probably even do it solo without the guide, at this point. After years of programming, and learning (or at least playing with) many languages, I've come to a philosophical conclusion of sorts:
C and Lisp should be the two languages all students start with, in my opinion. Probably SICP style Scheme education, and classic simple C89. C is the barest of the high level, the least abstracted, the most work. Students should build their own data structures, memory management, improved string handling, etc. I think this gives a really solid foundation of what other languages' features actually do, their benefits and trade offs. Then Lisp, to show what metaprogramming can do, and demonstrate the power that a language can have.<p>From there, sure, learn C++, Java, Rust, Go, Node.js, whatever toolset matches your industry. Start with the fundamentals, though.
