It's fun to be diving into something without worrying about "producing" something, other than the learning process that comes with the exploration. :) I expect so.

Fine. "When executed, this program will display 8 on STDOUT." It was a sketch, and I apologize for speaking imprecisely. Given that we don't actually know what we'll actually be doing yet, it's all hypothetical/"for instance" speculation. But, better that we are correct in the details of our speculation. Er. Fine. “When executed, this program will display 8 on STDOUT.”

When compiled and executed, it should return the number 8.

Your C program doesn’t “return” anything (which is a problem (main return an int)) but “print” the integer 8.

I wonder if the physical component (having a board, assembling it) is a necessary bridge for some kinds of learners to make them feel like computing is something "real," since it's often approached from the side of abstract mathematics, which not every teenager is particularly keen on. In other words, is computing being tangible a prerequisite for it being accessible? If so, what parts of computing, and to whom? I'm sure someone, somewhere has done research on this, but I'm not sure where you'd begin looking, other than trying to do a meta-study on "instead of only standing at the whiteboard, we built robots, and student interest went up" papers from journals of engineering education (and that seems a poor way of doing it).

We should be promoting peermanship (if that's not a word, it's mine now!). On a larger scale there is the separation between client user at home and service provider that you purchase from. I look at the financial dust bowl heading our way and frankly I have to say there are no solid local communities, local economies, and local industries to grab a hold of when this tangled skein finally unravels taking with it all real property in its path. The only ones who make it in the next few years are those who have both knowledge and tools and the only communities which will make it are those who have both consumers and producers at very short distances from each other. I will suggest then the best solution might be a gradual upward path from the low cost needs of the freshman to the productive needs of the seniors with open opportunities for those who want to participate in higher levels. Freshmen should get a cheaptop and use the network. Sophomores should get an upgrade on CPU/RAM/Hard Drive and use the cloud for making their projects. Juniors should get a snazzy machine and add it to the cloud for sophomores to use. Seniors should have a multicore boxes and have satellite clouds dedicated to their field. Graduates should offer their clouds on the open market for extra cash while they go to work or continue their studies. That's what I call a "recovery". I used to argue with people metaphorically thus about the economy: We're outta gas! No, you have a hole in your tank. That's a conspiracy theory! More gas you selfish person (irony was lost on them). You're gonna waste it on the road. Well, I was wrong. It's worse. There is no gas tank. Or maybe there is no engine, certainly no pistons if there is one. And the tires are made of papier mache.
