Social Media isn’t new

Posted on

It started over the Christmas break, and built from there. We started talking about social media and how each of us used it and viewed it. Most apart from me seemed to use Facebook, about half had a list of people they followed on Twitter, and two of us used LinkedIn. There was a smattering […]

Disappointing NBN

Posted on

It’s earlyish 2018, and the NBN should be here. In fairness, for some people it is.  I work with someone who really does get 100Mbs from their fibre-to-the-home service, but I also know people with no NBN service, or something substandard. All that comes over as a bit mysterious and geeky, which is a reasonable […]

Biometrics

Posted on

It’s a mixed blessing, but biometrics are here to stay. That’s an odd statement, so let me explain what I mean. We need to start with authentication, which is the process of identifying yourself so that you can get access to things you should have access to, like your bank account.  Way back in 1977 […]

NBN Terminology

Posted on

As is all too common in IT, or the computer industry if you prefer, trying to understand anything about the NBN means struggling through a world that seems to consist entirely of acronyms. NBN! See what I mean? So, let me use this article to help. I’ll provide some of the acronyms, let you know […]

SETI

Posted on

SETI stands for “Search for Extraterrestrial Intelligence”. Yup, we’re looking for aliens. And, contrary to what the conspiracies say, we haven’t found any yet. But it’s helpful to understand why. After all, we’ve been looking for 50 years now, surely if they were out there we’d know by now? Wouldn’t we? Not surprisingly, it isn’t […]

GPS

Posted on

GPS (or Global Positioning System) gives rise to more misunderstanding and low-grade conspiracy theories than almost anything else. GPS is about navigation. It’s a major part of the maps so many of us use in the car when we need directions. But, and here’s the important bit, the GPS system does not know where you are. […]

The Cloud

Posted on

Everything seems to revolve round something called “The Cloud” these days. But what is this mysterious cloud? It’s clearly important and has a large impact on society, but it’s not usually explained. So, let’s try. We have to start with computers, lots and lots of computers. Not the kind of personal computer you buy from […]

The Internet

Posted on

There’s a lot of misunderstanding about the Internet, and, to be fair, not many people care where it came from anyway. It’s pervasive. It affects just about everything we do every day, to the extent that we don’t really think about it much. But it has a history, and bits of it are interesting. It […]

The Future from 1960

Posted on

Growing up in the 1960s, the year 2000 was the distant future. From the magazine articles I read, everything we wanted would be available. Flying cars were a certainty, living in space, and some of us would have a house on the moon. And electricity from atomic power stations would be so cheap, the government […]
