Social media is kind of depressing. On one hand, we love knowing what's happening in the lives of others. On the other hand, everyone seems happier, better looking, and more successful than you. We're putting on a facade by posting statuses and writing comments that present the person we want others to think we are, rather than truly expressing ourselves. Yes, social media has facilitated movements and miraculous events, but let's be real. For the most part, none of it matters.

Google's Pixel phones have a feature that lets you swipe down on the fingerprint scanner to open your notification shade and Quick Settings panel.

Ever been in an argument, only to have the other person cop out by saying "I never said that," when you know full well they did? Or how about one of those times when you're sitting in the lecture hall, half dozing off to your professor's monotone ramblings, when your ears perk up because they somehow know you missed something important that was just said?
The start of a new year is generally thought of as a chance to start over, a time to improve or "fix" things in your life. Yet most people who set stringent New Year's resolutions find themselves failing within weeks—or even days—of setting their lofty goals.
Chestnuts are roasting on an open fire, which can only mean one thing: Christmas is nearly here.

Using the overview screen (aka recent apps) is a simple way to jump back to a previous task to continue where you left off, but as you use more and more apps, jumping back to that initial task isn't really that "recent" with all of those new tasks stacked on top of it.

Apple scrubbed the floor clean of all existing text-bombing apps in the iOS App Store, and even though there were once a ton of these apps in Cydia, the go-to store for jailbroken devices, there few and far between these days. If they do exist, they either cost money or don't work as advertised.
