The consensus is growing: Apple Music is a mess.

The latest person to add his voice to this chorus is Bob Lefsetz, who writes a popular music industry newsletter. 

Like me, Lefsetz finds the new Apple Music app to be really frustrating when we try to play our existing music libraries. The new app eliminated a bunch of features that we used to take for granted, like the ability to play all music by a single artist in random order, and hid a bunch of other features under layers of menus.

But Lefsetz says this isn't just about Apple Music. He takes it as evidence that Apple under Tim Cook has forgotten the simple rules of innovation that Steve Jobs knew, and that Clayton Christensen wrote about in "The Innovator's Dilemma."

As he puts it:

When you encounter disruption, you save your enterprise by building a cheaper, less-profitable operation across the street. And eventually there comes a tipping point when the new enterprise subsumes the old. You don’t mix them together. If you’re trying to placate your old customers, you’re screwing the new, and that’s death.

Steve Jobs never did this....

Apple realized MP3s were dying. At least I hope they realized this. But they were fearful of not only cannibalizing said business, but alienating iTunes customers. Instead, Apple decided to hamstring both old and new listeners, which is important, because companies that do this fail.

You jump over the fence and join the revolution. You don’t bring the old to the new. It’s what hobbled Microsoft.

I'm not sure the implications are that dire.

But to me, it appears that Apple lacked confidence in the subscription service, so tried to make the app guide people to subscribing in every way possible — and if that meant compromising the experience for non-subscribers, too bad. They may get a lot of trial subscribers, but unless they fix the experience fast, they're going to lose them.

If you've already read the entirety of the Harry Potter series, watched the films multiple times, and still find yourself craving more magic, you're in luck. 

Pottermore, J.K. Rowling's website devoted to all things Potter just got a complete makeover, complete with a new features section where fans will find everything from Hagrid's insights to how to make wands.

Rowling also released a short history of the Potter family tree, titled "The Potter Family." Dating back to the 12th century, it's sure to satisfy even the most loyal Potterhead. 

Keep reading to learn 17 things you've always wanted to know about the Potter family. 

The Potter family is not a part of the "Sacred Twenty-Eight," the list of the 28 families who were still of "true blood," by the 1930s.

"The anonymous compiler of that supposedly definitive list of pure-bloods suspected that they [the Potters] had sprung from what he considered to be tainted blood," Rowling explains.

Never fear, the Potter family history is still "illustrious" thanks to their connection to the "Deathly Hallows," the three legendary magical objects that make a person the master of death.

In Matt Damon's latest thriller "The Martian," NASA doesn't just play a key role in the movie — the agency was also an important consultant in the making of the film.

The movie is based on the best-selling recent novel by Andy Wier and explores the story of Mark Watney, a man marooned on Mars, and his struggle to survive. 

While the premise is science-fiction, much of the NASA equipment and technology featured in the film is scientifically accurate. Here's a comparison of all the awesome, seemingly science fiction elements of the movie that actually exist as science fact.

Make sure you don't miss them when you see the film, which premiers on Oct. 2.

SCIENCE FICTION: Mark Watney spends most of his time on Mars in what he calls "the Hab," — short for Mars Lander habitat — which shields him from harmful radiation, contains breathable air, and protects against the sub-zero temperatures on Mars.

SCIENCE FACT: This is NASA's Human Exploration Research Analog (HERA). It's a three-story habitat that spent some time in the Arizona desert to test its equipment under intense arid climates similar to Mars before reaching its current home at Johnson Space Center in Texas.

SCIENCE FICTION: Perhaps the most impressive piece of machinery in Watney's arsenal is this Mars rover. It won't travel any faster than 15 mph, but it gives him great opportunity to explore the Martian surface.

NOW WATCH: Inside the insane life of Facebook billionaire Sean Parker

Every one of us is made up of atoms that were once part of an exploding star, including atomic carbon, nitrogen, and oxygen — some of the fundamental ingredients for life.

Over billions of years, these ingredients condense to form gas clouds, new stars, and planets, which means that the ingredients, and therefore the potential, for life beyond Earth are scattered across the universe.

What's more, a number of recent discoveries also strongly suggest that alien life exists, either in our own solar system or beyond.

The ultimate question is no longer "Is there life beyond Earth?" but rather "Will we ever find it?"

Here's what we know:

Earlier this year, a team of scientists estimated that about 4.5 billion years ago at least one-fifth of Mars was covered in an ocean more than 450 feet deep. Any signs of life that swam in these waters could therefore be hidden in the Martian soil.

Read more about the study here.

But water isn't enough. You also need time. As it happens, a study last August discovered that water had existed on Mars for 200 million years longer than previously thought. What's more, there was life on Earth the same time as some of the last lakes on Mars.

Read more about the study here.

Asteroids and comets are key to the formation of life on Earth, scientists think. In particular, comet impacts, according to a report last August, likely caused amino acids to combine and form the building blocks of life. From what we know about solar-system formation, there are other comets in other planetary systems that could be doing the same thing right now.

There is a rare total lunar eclipse on Sunday night that won't happen again until 2033. Learn more about how to watch here.

So while you're looking up enjoying the view, we wanted to tell you about some of the other spectacular sights that will be out that night.

Especially because when the moon is eclipsed, it will make for a particularly dark sky, which is great for observing some of the fainter objects you can't normally see during a full moon, NASA astronomer Mitzi Adams told Business Insider.

We spoke with Adams about some of the planets, stars, and galaxies that you can catch Sunday night — if you know where to look.

We've used the free software Stellarium to pin point where these nocturnal attractions will be during the time of the eclipse. Check them out below:

The lunar eclipse will begin at 9:07 p.m. ET, but if you are on the East Coast and get outside about 40 minutes earlier, then you can watch the planet Saturn set along the western horizon. If you're on the West Coast, Saturn will be higher in the sky. (You can change the settings on Stellarium to fit your location.)

Saturn is the farthest planet you can see without a telescope. It's about 750 million miles from Earth.

When totality begins at 10:11 p.m. ET, the moon will begin to turn a deep blood-red color. Look to either side of the moon with a telescope and you can see the planets Uranus and Neptune. Here's what the sky will look like at 10:11 p.m. ET along the East Coast.

CNN anchor Jake Tapper confronted Donald Trump on Sunday for placating a supporter who spouted anti-Muslim conspiracy theories.

At a Thursday town-hall event, a man presented multiple inflammatory claims to Trump, including the widely debunked allegation that President Barack Obama is a Muslim.

But Tapper bluntly pressed Trump on the man's broader declaration that Muslims were a "problem."

"You're not responsible for what he says, but this is raw, unvarnished, ignorant bigotry," Tapper said. "You are a leader. You are the front-runner in the Republican race. Do you not have a responsibility to call out this hatred?"

Trump suggested that the CNN "State of the Union" host was simply trying to be "politically correct" and defended the idea that some Muslims were a serious problem.

"I have friends that are Muslims," the real-estate mogul said. "They're great people, amazing people. And most Muslims — like most everything — I mean, these are fabulous people. But we certainly do have a problem."

"What's the problem?" Tapper asked.

"Well, you have radicals that are doing things," Trump said. "I mean, it wasn't people from Sweden that blew up the World Trade Center, Jake."

Tapper tried one more time, noting that the Trump supporter had directly told the candidate: "We have a problem in this country. It's called Muslims." There wasn't any reference to extremism, Tapper said.

"What if he had said, 'We have a problem in this world — it's called blacks?'" he asked Trump. "Would you have said something then?"

Trump insisted that he never acknowledged his supporter's allegations about Muslims and that it wasn't a big deal at the event.

"I actually didn't respond," he said. "It was a question that was asked in front of a totally packed house. Nobody thought much of it until the following couple of hours, when it came became a pretty big subject. But, no, we do have a problem with radical Muslims."

The discussion then moved onto other subjects.

NOW WATCH: The story behind the famously offensive twitter account that parodies Wall Street culture

"Shark Tank" fans who know 37-year-old Ashton Kutcher from his comedic roles in films and sitcoms may have expected his appearance as a guest Shark on Friday's episode to be strictly for entertainment value. But after watching the seventh season's premiere, they'd see he's a formidable investor.

Kutcher made a deal, imparted valuable insight to entrepreneurs, and even sparred with Kevin O'Leary.

We recently spoke with "Shark Tank" mainstay Robert Herjavec, who said he found Kutcher's time on set earlier this year to be very impressive.

"It was interesting," Herjavec said. "He came on and he filmed for the day. ... After the first pitch he looked at the rest of us and went, 'Whoa, what just happened?' But to his credit, by the third pitch, he was right in there. He's a very savvy business guy."

Kutcher explained in an article for his website A Plus that it was his friend, the outspoken Shark Mark Cuban, who convinced him to audition for a guest role this season. He was initially reluctant, wondering if he'd be able to add value to investors outside of his expertise in consumer tech startups, and he had reservations about how authentic the deal making would be. Cuban convinced him it was not only real but that he could introduce some of his fans to a new side of him.

Kutcher has been involved in business ventures since starting his production company, Katalyst, in 2003, and has been an investor through his venture capital firm A-Grade Investments. He's made successful seed round and Series A investments in companies like Uber, Airbnb, Spotify, and Soundcloud. His mentor has been the prominent Silicon Valley angel investor Ron Conway.

And while he hasn't previously invested in companies similar to those on "Shark Tank," Kutcher did go in on a deal with Lori Greiner for a product in a radically different space. He and Greiner agreed to split a $200,000 investment for 15% each of Beebo, a shoulder strap that holds a baby bottle for optimal bottle feeding. Kutcher and Greiner decided that Greiner could use her expertise to improve packaging and presentation, and Kutcher could use his name recognition, massive social media outreach, and role as a new dad to get Beebo the customers it needs.

As Herjavec explained, Kutcher may have started a bit hesitant in the Tank, but after warming up, not even O'Leary's attacks fazed him. When O'Leary began dismissing the merit of entrepreneur Jess McClary's McClary Bros. drinking vinegars company and her ability to grow it, Kutcher stopped him to say, "You're belittling people, and that's not OK!" and made him stop talking so that he could speak.

And even though Kutcher, like O'Leary, was not interested in making an investment in McClary Bros., he used his time to explain to her how she has a great opportunity to expand beyond the world of cocktails into the health market with her products.

"Part of being [on 'Shark Tank'] is being able to have fun and being able to go after each other and at the end of it going 'it's just business,'" Kutcher told A Plus. "That being said, there are definitely times where you feel like you got burned, and you just gotta big boy up after that."

Beware, spoilers ahead!

Jon Snow, is that you?

On Saturday, The Daily Mail tweeted a photo of a man sporting a a man bun on the set of "Game of Thrones," which is currently shooting its sixth season.

SPOILER ALERT: This Game of Thrones character might not be dead after all http://t.co/wnmju55SS8pic.twitter.com/sqoZJnKtj6

— Daily Mail Celebrity (@DailyMailCeleb) September 25, 2015

Jon Snow, who is played by actor Kit Harington, shouldn't be there. During the final episode of season five, Snow was horrifically stabbed by members of The Night's Watch, who left him in a pool of his own blood.

And yet, there was a Jon Snow look-alike on the set, man-bun and all, which Harington frequently sports to tame his long curly locks.

The sighting is further fueling the fan theory that Jon Snow isn't really dead. Some believe he could come back as a White Walker, the zombie-like creatures who take over bodies of dead people and wreak havoc, or he could be reincarnated as his wolf counterpart, Ghost. Others theorize that the red woman, Milesandre, could bring him back from the dead.

Harington himself made it sound like he was under "Game of Thrones" contract for another few years. But, if that was Harington on set, he may have just ben shooting a flashback. Multiple HBO producers have told fans to give up on the theory that their favorite "Game of Thrones" cast member is still alive.

One put it bluntly: "[Jon Snow] be dead."

And HBO's executive vice president of programming, Michael Ellenberg, recently delivered the same bad news.  “[Jon Snow] is absolutely dead,” he told a packed convention center in Edinburgh, Scotland in August.

But we know a man bun when we see one. And that certainly looks like Jon Snow.

NOW WATCH: The Dalai Lama says a female Dalai Lama must be attractive, "otherwise not much use"

Spoiler alert if you haven't read "The Martian."

As Elton John once said, it's lonely out in space.

And it's even lonelier being stranded on a planet millions of miles from Earth, without communication, adequate food, or much hope of getting back home. That's the grim prospect Matt Damon's character faces in "The Martian," the upcoming film based on the novel by Andy Weir.

Damon plays NASA astronaut Mark Watney, a botanist on a fictional mission to Mars. Watney gets stranded on the Red Planet when a massive dust storm gravely injures him and forces his crewmates to escape, leaving him for dead. But Watney survives, and faces the daunting task of figuring out how to stay alive on an alien wasteland until he can be rescued.

Watney's technical prowess enables him to tackle the practical problems of getting enough water, oxygen, and food.

But perhaps the greatest hurdle he faces is psychological.

We talked to a NASA psychologist to find out if someone stranded on Mars could really make it without losing his or her mind.

"People have been able to keep it together mentally before" under extreme circumstances, such as being prisoners of war, Al Holland, a senior operational psychologist at NASA, told Business Insider. "We know that humans can be very resilient. One thing humans do very well is adapt."

One thing that's important for staying sane on journeys to space is real-time communication, which helps astronauts feel connected to friends and family. Thankfully for most of today's astronauts — including NASA astronaut Scott Kelly, who's spending a year on the International Space Station — communication is delayed by only a fraction of a second.

But on Mars, there would be a lag of about 20 minutes each way, which means a single exchange would take 40 minutes. In "The Martian," Watney faces the added difficulty of having to communicate with NASA using the camera on an old rover, which NASA can only use by pointing at letters and spelling out words. Talk about frustrating.

In the movie and book, Watney copes with the prospect of almost certain death using humor. At one point in the film when he's figuring out how he's going to survive, he says, "I'm gonna have to science the shit out of this."

A sense of humor is a huge asset for anyone, particularly for an astronaut, because it allows him or her to remain positive. Studies have shown that people use humor to cope with everything from losing their vision to having cancer.

Holland says it's also completely healthy for someone who is completely isolated to start having relationships with inanimate objects (think Wilson the volleyball in the film "Castaway"). As for Watney, he develops a kind of relationship with the camera he uses to log his captivity on Mars.

Keeping focused on actively doing things is also important for avoiding depression like the kind that Mark Watney might have experienced (psychologists call this behavioral activation). For example, people who are kept in solitary confinement will do things like construct a house in their mind, brick by brick, Holland says. In Watney's case, he throws himself into solving each problem that presents itself on Mars, MacGuiver-style.

But when it comes to training astronauts in the real world, NASA prepares them to work in teams, not on their own. "It would be a very rare situation to have somebody left by themselves," says Holland, but "we also plan for the worst-case scenarios."

Although NASA trains its astronauts to deal with solitude, American astronauts still felt isolated when they flew to the Russian space station Mir in the 1990s, according to Holland. The predominant language was Russian, and communication with family on Earth wasn't reliable.

Astronauts have different strategies for keeping busy in space. Some read, some make things, and others focus more on their work. But astronauts going to Mars will likely have to be even more independent, more focused, and more resilient than those of today are.

The Martian premiers on Oct. 2.

NOW WATCH: Matt Damon is left to die on Mars in first trailer for ‘The Martian’

During the press conference at the New York Film Festival for the premiere of his new film "The Walk," Joseph Gordon-Levitt revealed that the highwire artist he portrays in the movie, Philippe Petit, trained him how to walk the wire. 

"The Walk" looks back on Petit's memorable walk across the World Trade Center Twin Towers in the summer of 1974. 

"Philippe insisted that he be the first one to teach me how to walk on the wire," Gordon-Levitt told the theater filled with press following the screening.

"He doesn't do anything half way, this guy, so he orchestrated this really elaborate workshop. It was just me and him all day long for eight days straight and he said 'by the end of these eight days you'll be able to walk on the wire by yourself,' and I thought that sounded ambitious but he's such a positive thinker. By the end of those eight days I did walk on a wire by myself."

Though in the film, directed by Robert Zemeckis, many of the highwire stunts were done through CGI or a stunt double, Gordon-Levitt did explain that a set was constructed of the top two stories of the World Trade Towers with a wire 12 feet high that he walked on himself.

Gordon-Levitt noted that many on the film told him not to worry that much about doing the highwire walks himself because it would all be done by "movie magic."

But that wasn't enough for the man whose life he's playing.

"I really wanted to learn," Gordon-Levitt said. "But Philippe really wanted me to learn how to do it."

"The Walk" opens in theaters October 9.

NOW WATCH: This surfer's paradise — where officials say debris from MH370 washed up — is better known for deadly shark attacks

Despite decades of life in the public eye, Donald Trump seems to have a pretty good memory of the things he has said.

In an interview on "The Late Show" on Tuesday night, host Stephen Colbert played a game with Trump. The late-night host asked Trump to distinguish between Trump's own statements and statements that Colbert's conservative alter ego said on "The Colbert Report."

"For years I played an over-the-top conservative character — not as long as you did," Colbert quipped.

"I was looking back over some of the things you said over the years, and sometimes I couldn't figure out whether I said them or you said them. So I'd like to know if you can help me figure this out."

The real-estate mogul managed to identify all of his own quotes, occasionally by process of elimination.

Colbert read a tweet that Trump posted complaining about the cold weather and declaring that "we need global warming."

"I think it's you, but it's close to being me," Trump said, grinning.

Trump easily pointed out which quotes were Colbert's, at one point even pointing at Colbert before he finished reading his quote.

"You know you pretty well," Colbert said.

"I know," Trump responded.

In other parts of the interview, Colbert prodded Trump on policy. He served up to Trump what he called a "meatball" in an attempt to clarify whether Trump still thought President Barack Obama was not born in the United States. And he asked Trump to explain his proposal to force the Mexican government to pay for a border wall between the US and Mexico.

The new "Late Show" host appears to be embodying the less politically charged role of a traditional late-night host rather than that of his confrontational Comedy Central character, who was once so feared by politicians that Rahm Emanuel, then the Democratic Caucus chair, advised his caucus not to sit down for interviews on Colbert's show.

Colbert did, however, ask Trump whether he would like to apologize to anyone who he had offended.

"No," Trump said, before thinking a moment. "Maybe the audience."
