So, last post I talked about the technical interview and unquestionably students at elite private schools have yet another leg up on the other folk. Today, let's look at the core subject of those interviews and what I think should be emphasized in class. I want to be clear - I'm only talking about in class here. There are many things that can be done at public institutions like Hunter to help better prepare students for tech careers.

It's spring break and for me that's always been a good time to explore some new ideas. Here's one that some of you might like, particularly if you're teaching APCS-A or something similar. Many APCS-A teachers do a unit on image processing using the picture lab (alternate resource). Image processing is a nice platform to explore two dimensional arrays. You basically use a 2D array of pixels (points) to represent an image.
