The problem with most blockchain "explainers" is that they provide more detail than what matters to most people, using language that is foreign to most people, which winds up leaving people more confused than when they started. Instead, without worrying about being a technically perfect description, here's an explanation of blockchain your parents could understand.

Computer specs can be a baffling mix of acronyms and numbers at the best of times, but it's worth learning something about them: It will help you choose a new computer, troubleshoot your old computer, and generally understand more about the relationship between the specs on the page and the experience you're getting.

One of the biggest hassles with having multiple computing devices is being able to access your data in the office, at home and when travelling. Back in the 1990s, when I started working in IT, Microsoft had a crack at this with the Briefcase feature that was part of Windows 95 but it was pretty poor.

By the mid to late 2000s, cloud storage services came to the fore, making it easy to access up to date versions of our workfiles wherever and whenever we wanted. But how do we use these services and get the most out of them?

Mathematics is all around us, and it has shaped our understanding of the world in countless ways. The following 17 equations changed the course of history - we explain what they mean.

The decisions we make in life often come down to Bayes' Theorem, but most of us don't even realise what it is. So how does it work?

There’s nothing quite like the sound of snoring as the ultimate sleep interrupter. But snoring can be more than just a frustration to those in your vicinity. Sometimes snoring is linked to more serious health problems, such as obstructive sleep apnoea. An emerging line of research suggests snoring may directly contribute to cardiovascular health problems.

After thousands of years of trying, mathematicians are still working out the number known as pi or “π”. We typically think of pi as approximately 3.14 but the most successful attempt to calculate it more precisely worked out its value to over 13 trillion digits after the decimal point. We have known since the 18th century that we will never be able to calculate all the digits of pi because it is an irrational number, one that continues forever without any repeating pattern. But there is a semblance of order to all that "random" chaos.

While we often get hung up on matters of privacy and security when it comes to the actions of governments and law enforcement, there’s also the matter of privacy at work.

The fact that Amazon controls a vast swath of cloud computing services became dreadfully clear on Wednesday morning when a string of errors brought countless websites to their knees. This consolidation of power is, perhaps suddenly, a very big problem.

Some of us can definitely say we have a sweet tooth. Whether it’s cakes, chocolates, cookies, lollies or soft drinks, our world is filled with intensely pleasurable sweet treats. Sometimes eating these foods is just too hard to resist. But is it actually "additive" in a biological sense? Let's take a look at the science.

Think about something that happened to you this morning. That there, is your memory. We recall thousands of events and procedures every day, but how exactly does the brain do it?

Hospitals across Melbourne were put on emergency alert on Monday night as thousands of people called ambulance services, reporting breathing difficulties and other severe symptoms. Emergency rooms were so strained that day units were opened to handle the overflow. It was a severe outbreak of the phenomenon called "thunderstorm asthma" — but how does an emergency like this actually happen?

If you suffer from itchy eyes, a runny nose, headaches and excessive sneezing this time of year, you’re certainly not alone.
