We also talked about CLI vs GUI, ASCII and Unicode, SSH vs FTP, javac vs java, etc. We also talked about the importance of comments and self-documenting code!
What's new this year is that I'm trying to stick to a CLI for coding in java all day every day! All we need is a shell or terminal to run javac, java and a text editor. This way we call login from home and do our work the same way we do in class even from a Mac terminal or by using putty in Windows!
