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.

Recognising the limits of recognition protection
Life, James Hein, Published on 06/12/2017
» So how good is biometric protection really? In a recent TV series, I watched as the good guys artificially massaged the bad guy's heart to activate the biometric-fingerprint system on his phone. Many modern biometric systems require some evidence of life to work, so the old system of just severing a finger is no longer reliable.

Microsoft ditches Windows Pro 7, 8.1
Life, James Hein, Published on 09/11/2016
» Microsoft no longer provides the Windows Pro 7 or Windows 8.1 operating systems. This is no surprise as Microsoft flagged the end of October as the time that would happen, meaning every new PC will only have Windows 10. This is all part of the Redmond master plan to move everyone to an operating system as a service platform in the near future. This would mean that you won't own any of the MS software on your PC but simply renting it.

These offers take various forms, but the most common one is the chance to win something for free, where your chances increase with the more friends you get involved with and then there are the mandatory pages of offers that you need to say "no" to, in order to complete the application.

New camera is weighing on my mind
Life, James Hein, Published on 24/09/2014
» I've had it for a while now so I finally decided to upgrade my SLR camera. After some research I decided on a Nikon D5300. Nikon, because that's the brand of the lenses and other camera accessories I already own; and the D5300 because it's lightweight and has all the latest features found in mid-range models. If I was going to match my old D200 I probably would've gone for the D7100 which has more knobs that I will ever need and is also a lot heavier.
