Seasonal Amazon work-at-home jobs

Q: Christmas is right around the corner. Is Amazon hiring people to work at home during the rush?

A: You’re right on the money. Amazon hires an army of seasonal workers to fulfill orders from home. The money isn't bad, depending on your budget, but you should probably know what you're getting into before you sign up: There is a rigorous training program, and these are not permanent positions. Don’t expect to keep your gig past early 2018. But if you are a disciplined telecommuter, working for Amazon should beef up your paycheck through the New Year.

Find teens’ Facebook accounts

Q: Is it true that kids have two social media accounts, one for parents and another for friends? How do you find both?

A: This kind of bait and switch is as old as adolescence itself: A teenager says, “Bye, Mom, I'm going to Jenna’s house to study!” But what she means is, “Bye, Mom, I'm going to Jared’s house for a kegger his parents don't know about!” Social media only makes this deception more sophisticated, allowing high schoolers to create, say, two separate Instagram accounts, one that is parent-friendly and another that is “uncensored.” Click here to find out whether your child has fake accounts.

Test your firewall

Q: How do you know if your firewall is really working and keeping you safe?

This process can seem complex and technical at first, but if you take it step-by-step, you should be able to figure out how effective your firewall is. Click here to determine whether your firewall is actually working.

Share large files

Q: It’s so frustrating. I want to email a file, but my mail server says the file is too big. So what can I do then?

A: Sending large files by email is quickly becoming a thing of the past.
