Life is filled with deep, complicated questions and you don't learn any of the answers during your scholastic education. Enter the School of Life app on iOS, where you can watch insightful videos, have intelligent conversations, and hopefully find some answers.

Hackers are using Apple's "Find My" service to remotely hold devices for ransom, reports MacRumors. Multiple people have tweeted about stolen accounts in the past week. Two-factor authentication does not prevent the hack.

Your data, from the Christmas party photos you took last year to the tax return you filed (thank God for extensions, right?) is in more places than you think, which means securing as much of it as you can is vital. But the idea of encryption can be intimidating to the inexperienced, and often involves discussion of more esoteric topics like PGP, decryption keys and other terms with which you may be unfamiliar. Fortunately, iOS and Android make it easy to secure your data and protect it from malicious hackers and anyone looking to extract personal information.

Bluetooth technology can be a godsend for those of us trying to minimise the amount of cord clutter in our digital lives. But when your laptop, phone, or other device is hooked up via bluetooth to a wireless speaker or pair of headphones and the audio playback starts to stutter, it can be nothing short of infuriating.

iOS 11 is lying to you. Sure, the operating system is full of new features, fixes, and a generally more pleasant aesthetic, but one change is rubbing me (and other battery-conscious users) the wrong way. The revamped Control Center's actions when dealing with the disabling of wireless connectivity are misleading, telling users their Wi-Fi and Bluetooth connections are off when that isn't the case.

iOS: Having an elaborate, secure password on your Wi-Fi network can be a great thing. A great thing until that weekend you have guests visiting from out of town and they have to try your 20-character Wi-Fi password a dozen different times because a zero looks like an O or they couldn't tell from your chicken scratch which letters are capitalised and which aren't.

Everyone does not have more friends than you, even though, as a study at UBC Vancouver indicated, plenty of people believe their friends all have more friends. Everyone is not going to parties you're not invited to, meeting a wide array of people across all backgrounds and slices of life, who come together in a rich tapestry of social circles that rivals the opening titles of Sesame Street.

Underwater sex poses a fair number of technical challenges, but people still fantasise about it. Blame movies such as Romeo + Juliet and Wild Things. If you're intent on fulfilling your underwater fantasy, here's how to do it well.

The European Commission paid €360,000 ($541,980) for a study on how piracy impacts the sales of copyrighted music, books, video games and movies. But the EU never shared the report — possibly because it determined that there is no evidence that piracy is a major problem.

The best online videos of the week, including: The new Tomb Raider trailer, Wonder Woman, Top 10 things you didn't know have hidden secret uses and Netflix is a joke!

Sleep habits. Fertility. Steps per day. Water consumption. There's a tracker for that — all of that. So it probably shouldn't have surprised me to read Dr Catherine Pearlman's advice for struggling parents, and yet it kind of blew my mind. When you're trying to change your child's behaviour and you're not sure if what you're doing is working, she suggests collecting some data and analysing it.

By now, it's likely that you've received your same-sex marriage survey form in the mail and you're ready to cast your 'vote'. We understand that things are a little confusing, so we've put together a video guide that will ensure you have your voice heard - whether you're voting Yes, or No.

"Can everyone hear me OK without this?" say the worst public speakers when they step up to the stage. If three people in the front row say yes, off goes the microphone. And then anybody who is hard of hearing (or listening remotely, or sitting in the back of the room) can't hear you. Use the mic.

While computers have been used by the military in creating simulations and training operators in the use of equipment, this is the first time I've seen something from the gaming world make it into production like this. The US Navy is using an Xbox controller to operate the periscope on Virginia-class submarines.

Is this the world we live in now? A world where new phones retail for more than $1500? Imagine all the things you could buy with that kind of money! Yep, the iPhone X comes in at a wallet-decimating $1579 in Australia but, as this infographic shows, some countries have it even worse than us.

iOS/Android: Instagram is a great place to share all kinds of fun visuals — except for your favourite GIFs. Instagram won't let you upload them. Fortunately, the Giphy app will let you do exactly that right on your smartphone.

Hi Lifehacker! I have a question for you, would love to get your expert advice. My Nexus 5x is still alive, but need to make an upgrade due to storage (16GB just doesn’t cut it these days…). Having been with a cheaper mid-range, I’m interested in what is the best out there at the moment?

I’m kind of leaning towards picking up a cheap Google Pixel seeing that prices are tumbling now the Pixel 2 is nearly here. What would you suggest?

iOS: You're trying to follow the Google Maps directions to a place you've never been before, and just as things start to get complicated your mum texts. A few seconds later you're put on a group email with everyone at the office and the new message notifications start flying in, as do more texts from your mum who wants to know why you haven't responded to her first text yet. You begin to regret ever teaching your mum how to text.
