Online privacy is an issue that is on everyone's mind (and rightfully so). Apple acknowledged these concerns by adding DuckDuckGo as a search engine option in both iOS 8 and Yosemite. DuckDuckGo, whose slogan is "The search engine that doesn't track you," does not track your searches or profile you, and it shows all users the same results rather than personalizing them.
Time lapse photography is a filming technique that uses a lower frame rate for capturing video than is used for viewing it, resulting in a video that appears to be sped up. For example, you might record people walking through a park at one frame per second and play it back at 30 frames per second, resulting in something akin to a Benny Hill chase. Basically it is the opposite of slow motion. This technique is ideal for capturing motion that is too subtle for the human eye to appreciate, such as star movement, flowers blooming or clouds developing. It is also good for seeing long term progress, like watching the construction of a skyscraper, from beginning to end, in just a minute or two. iOS 8 has added this functionality to the Camera app, so now you can make your own time lapse videos with your iPhone or iPad.
Creating your own time lapse video is quite simple. Open your Camera and scroll over and select the "Time Lapse" option. Now all you have to do is tap record.
Sometimes having to unlock your iPhone to access your Messages app can be a pain, so Apple has added a quick reply feature as part of its "interactive notifications" feature in iOS 8. This allows users to quickly reply to a message from the Lock Screen without having to unlock their iPhone. Here's how it works.
When you receive a notification on your Lock Screen swipe left on the message to reveal the blue Reply button. Tap the button then type your message in message box and hit Send. Your response will then be sent without having to unlock your phone.
iOS 8 allows you to change your display to black and white, also known as grayscale. To put your iPhone in grayscale mode, simply go to Settings -> General -> Accessibility and toggle the Grayscale switch to on.
iCloud Drive brings new functionality to iCloud for those running iOS 8 and OS X Yosemite. Even Windows 7 and later can join in the fun via iCloud for Windows 4.0. While iCloud Drive adds the ability to use Apple's massive data centers for general storage, there are limitations when using iOS 8.
Spoiler alert: there is no Finder equivalent or iCloud Drive app for iOS that provides browse access to all of the files stored in an iCloud account. Individual apps such as the iWork suite are iCloud Drive compatible, and will only provide access to files associated with the app.
