It’s no secret we’re very into data security and online privacy, and one of the easiest steps you can take is to use a password manager to generate (and store) strong, very-difficult-to-crack passwords. Even if you don’t care about the security aspects — perhaps you think you’re unhackable — they’re an incredibly convenient way to remember your passwords for all the sites and services you subscribe to.

Last year, Judd Apatow, Debra Messing and Rick Perry⁠ — the U.S. Secretary of Energy and guy in control of America's nuclear weapons — fell for a lie that’s been circulating on Instagram: that Instagram changed its policies so that they could use all of your photos, messages, and other information at their disposal. In reality, Instagram doesn't legally "own" your photos - but it can use them in any way it sees fit, forever.

We've all been taught to wash our hands after using the restroom. But do we really need to? Let's take a look at the science.

Dear Lifehacker, I've heard cow's milk is actually bad for you, or at least not beneficial when compared to the many alternative options. But if I shouldn't drink milk, what's the best alternative? Are any of them good? I've heard good and bad things about most, so how do I decide?

Dear Lifehacker, I'm on a fixed salary, which is based on the amount of hours I work per year. However, on leap years the pay remains the same as non-leap years. Shouldn't I be getting paid eight hours extra? Or am I expected to work an entire day for free?

Last year, Telstra embarked on a business blitzkrieg, demolishing thousands of legacy plans as it sought to consolidate its core offerings. While much has been written about Telstra's new mobile plans, the same strategy has been employed across broadband and the NBN. So which plan offers the best bang for buck? Let's take a look.

If you're not rich and aren't renting, it's a fair bet that you're putting aside a significant portion of your salary on mortgage payments. We've crunched some numbers to determine where you should live if you want to have as much income left as possible once the bank takes their slice.

If Rambo was a real person, the standing military press would be his favourite weight training exercise. A variation of the overhead press, it derives its name from its use in the military as a strength indicator.

If you want to get in shape, the military press is definitely a move worth mastering, as it targets the shoulder, upper arm and leg muscles simultaneously. Here's how to do it correctly.

Science has discovered the average.

Hello Lifehacker, How does one work out how much power their computer needs? I'm really confused about this, so please explain how I can calculate how many watts my power supply unit (PSU) will need if I upgrade. And any other tips on choosing one?

We all know that garbage has a terrible impact on our environment — take a look at the plastic bottles washing up on our beaches and in our waterways. But when it comes to the question of bottles versus aluminium cans, does one container have an even worse impact on the environment than the other?

Dear Lifehacker, I work in a typical 9-to-five office job. I can tell my posture isn't ideal and I catch myself slouching all the time. But when I try to consciously sit up straight, it quickly becomes uncomfortable and I slip right back to where I started within the hour. Do you have any beginner-friendly tips for easing myself into better posture habits?

Dear Lifehacker, Why is all pizza these days so salty? I don't just mean somewhat salty; I mean if I made my own and dropped the salt shaker in it that would still be less salty than my local Domino's or Pizza Hut. Can they add so much salt legally? Surely that can't be healthy.

Do pizza makers have to comply with any rules in this area or can they add as much salt as they want?

As a term and concept, “transgender” is now firmly embedded in common parlance and popular consciousness. By contrast, the term ‘cisgender’ - an important linguistic counterpart - only entered the Oxford English Dictionary in 2015.

Dear Lifehacker, One of my favourite animated movies growing up was Disney's Dumbo. My daughter just turned four and I want her to have the same magical experience watching it that I did. However, as an adult, I'm not entirely comfortable with the somewhat racist depiction of the anthropomorphised crows. Do you think I'm overacting, or should I censor this type of stuff from an impressionable child?

When I first heard about electric bikes, they struck me as the ultimate life hack. They allow you to commute relatively speedily without the hassle of public transportation, to get exercise without getting overly sweaty, to get from point A to point B without spending money on gas. As a longtime urban cyclist who’d sworn off bike commuting after a move put a sizable hill between me and the office, I wondered if electric bikes were the answer. I decided to find out.

Pouring sugar into a car's gas tank is thought to be a petty yet effective means of sabotage. As parodied on The Simpsons, it's the preferred revenge method of estranged (and deranged) spouses and partners.

The idea is that the sugar causes the car's engine to permanently seize up, resulting in a costly trip to the mechanic. The guys at Project Farm recently put this mischievous theory to the test. Here is the video.

So-called 'Greek yoghurt' has exploded in popularity in recent years, with Australia's major supermarkets all stocking multiple brands. It's now the number one choice for people who want a healthy alternative to normal yoghurt.

But hang on. Wasn't yoghurt always healthy? What's going on? It turns out there are certain health benefits — but also health drawbacks — to eating Greek yoghurt over the regular stuff. Let's take a look at the science.

We’ve been told there are many benefits of eating our veggies - and the number of people in Australia who follow vegetarian or plant-based diets is growing rapidly.
