TSA and tablets

Q. I'm flying with a tablet. Do I have to take it out of my backpack at the security checkpoint?

A. Any electronic gadget smaller than a 13-inch laptop can stay in your bag unless the TSA agents tell you to take it out. Even larger laptops can stay in the bag as long as you have a TSA-friendly bag. These are bags that open to let the laptop lie flat on the conveyer belt and have the chargers and other cords off to the side. Learn more about TSA-friendly bags and other tips for breezing through airport security.

Hoax links on Facebook

Q. A friend shared an outrageous headline on Facebook and when I clicked I got a picture of Leonardo DiCaprio saying I'd been tricked. What was that all about?

A. There's a site called URL Online that generates a ton of crazy headlines, such as "Legal Drinking Age in US Goes Up to 23 as of February 2016." If you click, however, you get the message saying you were tricked along with how many people have fallen for it. It's generally harmless, aside from people who don't know it's fake and start heated comment wars based on the headline alone. See the image you get if you click and learn how to spot these links.

Easier expense reports

Q. I need to turn in expense reports for work, but they're such a hassle. Is there an app to make it easier?
