I'm by the computer at the moment, but the room with the family computer is right by the kitchen, so I have easy close access to knives if I need to defend myself. Also, I have a dog, who's lovable and friendly normally but wouldn't hesitate to bite and maul someone who broke in. Finally, right by the computer is a pair of scissors in the stationary pot, they're pretty sharp, so in an emergency I could use those for stabbing intruders if I feel I'm in danger.
If I was in bed, well, I could drag my bookshelf that's by the side of the door into the door frame so that no-one could get in, then escape from my bedroom window, since it opens onto the roof of the back of the house and onto the conservatory. I'd be half naked since I sleep in my boxers, but still. Otherwise, the only weapon I have is my laptop, which is pretty damn heavy. I have no fear of damaging it, by the way, since it's already broken and I'll be replacing it with a top-range XPS 15 within the next month or so. I can use it as a blunt instrument. In that case, I'd take my boxers off first and charge screaming onto the landing with it, as hopefully the sight of a screaming naked madman wielding a computer would scare off any intruders pretty quickly
