However, as soon as you and your laptop leave the safety of your home, your laptop has essentially no protection if you don’t set up some sort of software firewall. So while your router’s firewall may be great, just remember: It can’t follow you out the door.
Arguing that it gets a bad rap because it’s a Microsoft product, many of you are perfectly happy with the default Windows Firewall. It’s built directly into Windows, runs quietly in the background, and blocks suspicious attacks without requiring you to install any third-party software.
Researchers are using a technique called simultaneous location and mapping (SLAM) to develop helmets that rescue workers can use to navigate through heavy smoke. The helmet features an infrared laser scanner and software that bounces signals off walls and uses that data to create a map of the surrounding area.
