This is a good read.

In a class I took with my thesis advisor, he explained the Hilbert Hotel similarly, and it was as entertaining then as this is now.

This is a hoot!

The halting problem is described on Wikipedia as:

Given a description of a program, decide whether the program finishes running or will run forever.

The halting problem is algorithmically undecidable because “there is no algorithm which can be applied to any arbitrary program and input to decide whether the program stops when run with that input.”

This is exactly what I learned in my undergraduate OO Java class. Now when I hear someone say that Java is pass-by-reference I’ll have a link to send them. Good article.
