  Seamless synchronicity

  Life, James Hein, Published on 11/09/2019

  » As I was walking to work thinking about this week's column, I did a quick self-inventory. I was listening to On Liberty by John Stuart Mill through my noise cancelling headphones. The audio was being sent by Bluetooth from my Samsung Galaxy S10 5G phone that I was also using to play a location-based game, Ingress. This was being fed my position by satellite and receiving information from the internet via my phone's data connection. Occasionally I would pull down the notification tab to see what was on for the day and who had tried to contact me via a number of social-media services.

  Do you have a fear of spying?

  Life, James Hein, Published on 11/10/2017

  » So how safe do you feel in your home security-wise? I'm not thinking of malware but the ability for someone to snoop on you visually or through audio. There have been some concerns about devices like the Amazon Echo and similar being used to tap into what you are saying with everything recorded on servers that authorities could get from say Amazon.

  Even writers need to think before tweeting

  Life, James Hein, Published on 16/08/2017

  » Without the internet, there would only ever be part of a story. Consider the recent example of Harry Potter author J.K. Rowling. She watched an edited video and then took to the internet using her fame to decry the treatment of a small child by a prominent leader. Her concerns were quickly and widely spread but the unedited footage showed the opposite. Even the mother of the child finally got involved and asked the internet to please tell J.K. Rowling that she was wrong. At the time of writing Rowling had apologised to the mother but not the leader she smeared. In the current fast pace and instant Twitter-response world it is important to take a step back and do some personal investigation before reacting, often incorrectly, to a flash tweet or news story. If you see a clip try and find the full or unedited version, that extra time can save you from future embarrassment, though some personalities seem to be immune to it.

  Apple sets sights on VR market

  Life, James Hein, Published on 21/06/2023

  » The biggest announcement of the past week or two was the Apple Vision Pro VR system. There has been so much on this recently. The quick summary is -- two 4K eyepieces, no controllers required and it can replace your TV and computer monitors. I was more interested in the battery life being two hours, or if you were using them, not enough for the full Apple presentation. The price is also an amazing US$3,500 in America so out of the range of most people. One argument is that by the time you don't need to pay for a TV upgrade or new monitors it is worth the investment. My counter is if you have a four-person household that price becomes $14,000, a lot more than the cost of a new TV. Oh, and you can mostly only use it with Apple kit which really limits options.

  Alternatives sought as chip shortages disrupt production

  Life, James Hein, Published on 31/03/2021

  » - There is a silicon shortage, which is another way of saying that getting your next computer will either be difficult with long wait times or that prices may rise soon, so you'd better get in earlier rather than later. A couple of fires, a cold snap in Texas and Covid-19 restrictions are some of the causes of the shortages which shows that it doesn't take a lot to disrupt supply chains.

  Covid computing

  Life, James Hein, Published on 06/05/2020

  » Things are quiet on the IT front. Well, that's not necessarily true, as many are trying to come to grips with the whole working-from-home existence. Many, including myself, are spending a lot of time in front of a screen. Instead of getting up and conferring with a colleague at their desk, it is a Skype chat. Instead of a walk to the meeting room, often on another floor, it is a Skype meeting or similar. Many do not have a video camera at home so it is voice only. There are new collaboration technologies like Microsoft Teams to get used to. Instead of handing a report to someone, it is uploaded into a shared area for all to browse. I find that I am sharing my screen more often to go over a document or diagram. On the plus side I recently had an upgrade to my Internet speed. This has helped with downloads but not much else, as a chat takes up very little bandwidth.

  Burning issues and great expectations

  Huawei still some way behind rivals

  Life, James Hein, Published on 21/11/2018

  » I've had some feedback expressing surprise that I invested in a smartwatch. Yes, I didn't think I'd see the day either, but it does function very well as a watch with changeable faces and at a price point that's far below some of the faces it can duplicate. The always-on test was a success in that I only turned the watch off when I wasn't using it on some evenings. It also does sleep tracking, which perhaps provides a sterner test, but it still provided a week's worth of use making it usable for many. On a longer trip you would need to take the charger along. Note that for both tests, I kept Bluetooth on the whole time.

  Translating ear buds and builder robots

  Life, James Hein, Published on 09/05/2018

  » Let's face it, technology is cool. Google is claiming that they will have translating ear buds you can use when you travel that will allow you to understand almost any language, instantly. Yes, it does sound like something out of a sci-fi book and I think they should name them Babel fish, but that name was already "stolen" from The Hitchhikers Guide To The Galaxy series in 2012 that later became Bing Translator. The good news is that first versions of these may be ready for tourists in the very near future.

  True cost of mining Bitcoin

  Life, James Hein, Published on 28/03/2018

  » Should you Bitcoin? Short answer in the past yes, now not so much. I've mentioned Bitcoins in previous articles and modern mining, which is how you get them, has driven up the price of graphics processors in recent times. Can you make any money using your spare GPU cycles on your PC? Answering that question is not as simple you might think, despite what a mining application may tell you. It depends on how powerful your GPU is, what the price of Bitcoin is that week and things like how much you pay for your power because you will be using more. The process works by maximising the power of your GPU, using more electricity than for regular use and keeping your PC hotter than usual 24/7. Mining works by solving complex maths equations for the blockchain which over time takes longer and longer and more processing power.
