What is an Operating System?&
Not all computers have operating systems. The computer that controls the microwave oven in your kitchen, for example, doesn't need an operating system. It has one set of tasks to perform, very straightforward input to expect (a numbered keypad and a few pre-set buttons) and simple, never-changing hardware to control.

Instead, the computer in a microwave oven simply runs a single hard-wired program all the time. For other devices, an operating system creates the ability to: serve a variety of purposesinteract with users in more complicated wayskeep up with needs that change over time All desktop computers have operating systems. In any device that has an operating system, there's usually a way to make changes to how the device works.

How to make an HDTV Antenna I wanted to watch the IBM Jeopardy Challenge last night, but couldn't find anywhere to stream it online, and I don't have cable. So, I decided to make an antenna for my HDTV. With only about 30 minutes until the show started, I didn't have time to make one of those fancy wood and coat hanger designs you've probably seen around the internet. I had to make do with just this spool of copper wire and some cardboard. I stuck one end of the wire into the coaxial cable port on the back of my HDTV, wrapped the other end of the wire around a cardboard tube, and stuck the tube in my window. There's no special math or measurements involved in this antenna design, it's just my best guess at the minimum viable product required to pick up a signal. So, how does it work? Thanks to my new antenna, I was able to watch the game in HD on the CBC.
