If you’re like me and you’ve recently had a new/replacement bank card, you will have probably noticed a slight change in the appearance of your new card.
The new wireless-looking symbol represents contactless payment capabilities based on radio frequency technology. This means that, in theory, you can make low transaction payments (up to £20 as of this article I believe) simply by tapping on an EPOS terminal without entering your PIN, probably saving you about half a minute every time you make such a payment.
If you have problems loading folders or e-mails in Outlook.com/hotmail you’re not the only one.

WPS stands for wi-fi protected set-up. It’s supposed to make it easier for non-tech savvy people to authenticate devices on to a wireless network by pressing a physical button on the router or entering a PIN in to a device to make it known to the network.
The problem with WPS is quite a big one. There are many fundamental flaws in the WPS model – I won’t go through these in this article but a simple Google search will expose these many vulnerabilities in WPS – one which I discovered by accident today is a relatively (scarily) easy denial of service on an end-users network.
ESXi acts as a really flexible and powerful monster of an operating system which can easily divvy up your server’s physical hardware in to virtualised components. These components can then be shared among tens of virtual machines depending on how you’ve set things up.
