Ask 100 chefs what the most important tool in their kitchen is, and you'll get 100 chefs saying the exact same thing: their set of knives. For home cooks and professional chefs alike, nothing is more important (or exciting) than a good knife. A good knife allows you to work mo ...more

No, your Apple Watch isn't totally hacker-proof, despite what some have claimed. The basic idea behind its security is that the Watch can detect when it is removed from a wrist, and automatically requires a passcode to be entered if removed (if one is set up, which is a requi ...more

Unwanted advertising is everywhere. Annoying pop-up ads, overly loud late night commercials, spam...it never ends. And before spam, there was junk mail. Junk mail is even worse because unlike TV commercials and internet ads, it's physical. You can't just delete or ignore it—an ...more

It's September 1st, 1859, and the Earth looks more or less like something out of an apocalyptic movie or Sci-Fi novel. All communications have failed, it's so bright outside at midnight that people are getting up and making breakfast, and people all over the world are seeing a ...more

When you need to drive somewhere unfamiliar, you probably use Apple Maps to get there if you're an iPhone user. But just getting there isn't enough sometimes. If you pull up to the location, and there's nowhere to park, it doesn't matter that you arrived on time since you'll b ...more

Many popular IoT devices have terrible security. For instance, a hacker who's on the same Wi-Fi network as a Sonos speaker can assume direct control over the device's behavior. If an IoT device doesn't secure the messages used to control it over a network, it's easy for somebo ...more

Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to snif ...more
