Feedback · It acknowledges actions and shows results to keep people informed. The built-in iOS apps provide perceptible feedback in response to every user action.

Clarity · Throughout the system, text is legible at every size, icons are precise and lucid, adornments are subtle and appropriate, and a sharpened focus on functionality motivates the design.

Clarity · Negative space, color, fonts, graphics, and interface elements subtly highlight important content and convey interactivity.

Deference · Fluid motion and a crisp, beautiful interface help people understand and interact with content while never competing with it. Content typically fills the entire screen, while translucency and blurring often hint at more.

Deference · Minimal use of bezels, gradients, and drop shadows keep the interface light and airy, while ensuring that content is paramount.

Depth · Distinct visual layers and realistic motion convey hierarchy, impart vitality, and facilitate understanding. Touch and discoverability heighten delight and enable access to functionality and additional content without losing context. Transitions provide a sense of depth as you navigate through content.

Aesthetic integrity · It represents how well an app’s appearance and behavior integrate with its function. For example, an app that helps people perform a serious task can keep them focused by using subtle, unobtrusive graphics, standard controls, and predictable behaviors.

Aesthetic integrity · An immersive app, such as a game, can deliver a captivating appearance that promises fun and excitement, while encouraging discovery.

Consistency · A consistent app implements familiar standards and paradigms by using system-provided interface elements, well-known icons, standard text styles, and uniform terminology. The app incorporates features and behaviors in ways people expect.

Direct Manipulation · The direct manipulation of onscreen content engages people and facilitates understanding. Users experience direct manipulation when they rotate the device or use gestures to affect onscreen content. Through direct manipulation, they can see the immediate, visible results of their actions.

Feedback · Interactive elements are highlighted briefly when tapped, progress indicators communicate the status of long-running operations, and animation and sound help clarify the results of actions.

Metaphors · People learn more quickly when an app’s virtual objects and actions are metaphors for familiar experiences—whether rooted in the real or digital world.

Metaphors · They work well in iOS because people physically interact with the screen. They move views out of the way to expose content beneath. They drag and swipe content. They toggle switches, move sliders, and scroll through picker values. They even flick through pages of books and magazines.

User Control · Throughout iOS, people—not apps—are in control. An app can suggest a course of action or warn about dangerous consequences, but it’s usually a mistake for the app to take over the decision-making. The best apps find the correct balance between enabling users and avoiding unwanted outcomes.

User Control · An app can make people feel like they’re in control by keeping interactive elements familiar and predictable, confirming destructive actions, and making it easy to cancel operations, even when they’re already underway.

Believe half of what you see and only some of what you hear, unless you hear it from me.

Maybe it's legitimate criticism, though it can be hurtful. Maybe I haven't paid sufficient attention to the people with whom I would have a natural affinity as a liberal, and they feel let down by that.

If I was discovered by anyone, it would be Stephen O'Neil, who saw me in a play at Williamstown and introduced me to my team who I'm still with today. He was the first person to introduce me to the film and TV world. Other than that, I just assumed I would be a theater actor my whole life.

Trolling taps into people's desire to poke fun, make trouble and cause annoyance.

For fear of dropping the troops in the sea, the pilots tended to drop them too far inland - some of them actually in the British lines. The weapon containers often fell wide of the troops, which was another handicap that contributed to our excessive casualties.

I've only had one serious boyfriend, but we dated for three years.

Now I've devoted my life to making sure that I can be a trailblazer for any other African American kids or any other gay kids or any other kids that just feel weird or uncomfortable and have their own issues and don't know how to express themselves. I want to be like a beacon for those kids now.

I've never pretended that I'm not female and vulnerable. To me, it's just being honest.

Music changes every three months. There's always new artists coming out. There's always new sounds. There is always a new hit coming out. You gotta stay relevant as much as you can and feed your fans as much as you can.

I think it's important never to look yourself up on Wikipedia. I think the temptation to correct any interesting factual errors would be too much.

I don't get a chance to do many of my own stunts on 'Buffy' - none of us do. We have amazing stunt people who make us all look really believable and really good.

He that will not reason is a bigot; he that cannot reason is a fool; and he that dares not reason is a slave.

A clear vision, backed by definite plans, gives you a tremendous feeling of confidence and personal power.

Timmy Horan was a childhood hero. He was a great distributor, elusive, good stepper, very physical, defensively very sound. What a rounded player.

It is better, of course, to know useless things than to know nothing.

The sum of the whole is plainly this: The nature of man considered in his single capacity, and with respect only to the present world, is adapted and leads him to attain the greatest happiness he can for himself in the present world.

I think the people that want to fly in space, who want to work in space, who want to go to station, these people realize that there is a risk inherent to what they do. They understand that there are possible off-nominal situations, dangerous situations in space, and there's no insurance against that.

I was induced to establish several orders of merit, from conviction that emulation, well directed, becomes a useful servant; and, that the latent genius of some youth is more easily brought into action this way, than by the more sordid gratification of self-interest.

Once in high school, I completely over plucked my left eyebrow all the way up to where you're not supposed to. I had no idea what I was doing and it looked terrible! My mom was like 'What did you do to yourself?' I was so embarrassed.

A word to the unwise. Torch every book. Char every page. Burn every word to ash. Ideas are incombustible. And therein lies your real fear.

My curiosity sustains me for the period of the shoot.

My mom always told me if I love what I'm doing, and I'm having fun, then just continue to do it. But if it's not fun for me anymore, and I'm miserable, then I'm going to go back to Texas and quit it all, to be honest.

Adaptability is key.

If Republicans are going in the wrong direction, I am still willing to stand up against them.
