A new semester, new tweaks to class

A new semester has already begun. The students have finished the Scratch portion of course. We are starting to going into Java, however, the students range from Freshmen and Juniors. There is a difference in foundation in the understanding of how computers work and how they think logically. I plan to infuse a bit more of how computers work as we learn Java. Should be interesting and hopefully will turn out well. For example, we are starting to look into how Java primitive ints work underneath the hood. We will see how 32bits limit the positive range up to 2^31-1 before it turns negative etc...
