Dear Lifehacker, I have a question that has been an issue for the last 3 years. So, I'll be honest, my boyfriend and I watch porn each separately on our phones. We each have gone through each others' phone activity through Google, and when he looks at mine, there are items in there that I never Googled, like live cams chat room stuff. I have never in my life entered this into my Google search but I have a suspicion that they are pop ups from the porn sites. I want to know how and why they come up as my searches. And there are other things that show up that I supposedly googled but I know for a fact I didn't. Can you help me, please?

Dear Lifehacker, We know using cheap, third-party cables to charge a smartphone is bad, but what about the little bricks that plug into the wall or nubs that plug into a car lighter? Are these safe to use or will they turn my iPhone into a ticking time bomb?

We've all been there. You plug something into your computer, wait for the ba-donk sound (on Windows, at least), and start navigating your flash drive / listening to your headphones / using whatever else it is you plugged in to your computer.

Sometimes, that doesn't quite happen. What gives?

This week alone, people in Syria have been gassed and then bombed. After years of horror, the pictures of suffering children even got through to the American president's cold heart. If you feel the same way, here are some things you can do to help.

Awareness events such as World Mental Health Day and RUOK Day are important for initiating conversations about mental health in the community. Anything to promote discussion in the media about what "mental health" means and how to seek help if you need it is certainly a positive thing.

However, reducing stigma is only one component of tackling this issue. With new research showing that Australia’s suicide rate is the highest it’s been for over ten years, it is clear that action must follow awareness. Clearly, a little more conversation and a little more action is needed. Here are some tips that might help.

It sounds like something that should go without saying, but if you're trying to offer praise and support to someone, an honest compliment will almost always work better than a feigned one.

Hi Lifehacker, I've just discovered that I cannot claim HECS-HELP repayments as a tax deduction. This makes no sense to me. If I pay my course fees up front I can claim them as a self-education expense, but if I repay them to the government I can't? What gives?

The government's plan to charge up to 6% interest on HELP loans has been widely attacked as unfair. Many critics, including Shadow Education Minister Kim Carr, the Group of Eight universities, Universities Australia and HECS architect Bruce Chapman, have come out against pegging HELP loans to the bond rate, rather than CPI as it is now.
