If you edit a paper program, then won't the source on the paper be obsolete? Will that be indicated somehow? If I'm looking to see what a piece does, how can I tell if the source code on it can be trusted?

When a program is changed, Realtalk will print a red line over the lines that have been modified or removed. It looks a lot like the output that you'll see from a "git diff" on a file.

You mean like, from the projector?

[infinite8s]

The projector is just a means of getting dynamic media. You could imagine future technologies involving e-ink paper that's as cheap as wood-pulp paper. What if we had e-ink embedded in paint? What if all physical objects could be embedded with computability?

[jf]

Yes, sorry. It will project a red line on the paper.

[mcphage]

That's good, then. Having the code right there isn't very good if you can't trust it, but if it at least indicates what's not to be trusted, that's much better.

What happens when the school bully rips up my piece of paper?

[icc97]

To the down voters, it was a genuine question. If the programs are pieces of paper, either they are just toy problems or otherwise you care about losing the paper.
