My little brother wants to get into network security and I've been sending him tons of articles, some career advice from colleagues in the field and such. I am both tempted to show this link to him and also thinking he doesn't need to get his hands on something so portable. As smart and interested as he is, he's also only 16 and has some immature tendencies still. It's a real challenge for me and I'm going to have to think it over. Maybe show it to him, build it with him and use this as another opportunity to talk about ethics.
