Depending on your security and privacy settings on your Apple Mac, you may get a message that software or an app you were installing “was blocked from opening because it is not from an identified developer.” And when you try to override it, the ‘Allow’ or ‘Open Anyway’ button doesn’t work. The explanation below may be why!

If you have an iPad 2 or iPad 3 you may be wondering just where the heck the mute button is. On the iPad, original flavor, it used to be that little slider button next to the volume up and down rocker button. But now that button has been changed to the “lock/don’t lock” screen orientation button (while on the iPhone that button is the mute button and you’ll be looking for how to lock your screen orientation).

Someone at Amazon marketing is brilliant – launch a new product so novel, on March 31st – that you’ll get extra media attention with the “Is it an April Fool’s joke?” coverage. But the Amazon Dash button is no April Fool’s joke. And ultimately it’s all about the Internet of Things.

Amazon just announced its newest Kindle Fire, the Kindle Fire HDX tablet, which is 7-inches of awesome. However, it’s not different enough from the previous generation of Kindle Fire to warrant covering it – except for this one new feature: the Mayday Button. “What is the Kindle Mayday Button?”, you may ask? It is a controversial new feature that allows you to connect directly to an “Amazon expert” for tech support, 24/7/365.

Google, Microsoft, Apple, and Firefox’s Mozilla, have at last formally agreed to include a “Do Not Track” button (DNT button) in every browser. {Let’s take this opportunity to explain that the way this works is that using the “Do Not Track” option inserts a special “Do Not Track” header into your browser. In fact, as we shall see, there may not even be a DNT button involved – you may need to be a super-user type to even find the “Do Not Track” option.} Their capitulation comes just before the Obama administration’s appeal to Congress to pass a “privacy bill of rights”, but don’t expect it to mean that they won’t still be mining your data. (P.S. See below for how to enable Do Not Track in Safari.)
