What do you get when you mix one part action movie with one part holiday flick and add in a dash of sweaty tank top? Die Hard, John McTiernan’s genre-bending Christmas action masterpiece for the ages, which sees a badass NYPD cop take on a skyscraper full of bad guys in the midst of an office holiday party. Here are 30 things you might not know about the movie.

1. IT’S GOT A LITERARY BACKGROUND.

Think some action-loving Hollywood scribe came up with the concept for Die Hard? Think again. The movie is based on Roderick Thorp’s 1979 crime novel Nothing Lasts Forever, which is a sequel to his 1966 novel, The Detective. In 2013, Thorp’s long out-of-print book was resurrected to coincide with the film’s 25th anniversary.

2. IT WAS INSPIRED BY THE TOWERING INFERNO.

The idea for Nothing Lasts Forever was inspired John Guillermin’s 1974 disaster flick, The Towering Inferno. After seeing the film, Thorp had a dream about a man being chased through a skyscraper by a group of men with guns. He eventually turned that snippet of an idea into a sequel to The Detective.

3. FRANK SINATRA GOT FIRST DIBS ON PLAYING THE ROLE OF JOHN MCCLANE.

Because he had starred in the big-screen adaptation of The Detective, Frank Sinatra had to be offered the role in its sequel. At the age of 73, he smartly turned it down.

4. BRUCE WILLIS’ BIG-SCREEN DEBUT WAS WITH FRANK SINATRA.

In 1980, Willis made his film debut (albeit uncredited) in the crime thriller The First Deadly Sin. He has no name and if you blink you’ll miss him, but the role simply required that Willis entered a diner as Sinatra’s character left it. Maybe it was kismet?

5. CLINT EASTWOOD PLANNED TO TAKE A STAB AT THE PART.

Originally, it was Clint Eastwood who owned the movie rights to Nothing Lasts Forever, which he had planned to star in in the early 1980s. That obviously never happened.

6. IT WAS NEVER SUPPOSED TO BE A SEQUEL TO COMMANDO.

This is one of the most popular internet stories about Die Hard. But according to Stephen de Souza, the screenwriter of both Die Hard and Commando, while there was a sequel to Commando planned, the only similarity with Die Hard is that they both took place in buildings. According to de Souza, Escape Plan is the closest to his original Commando 2 idea and Die Hard was never supposed to be anything but Die Hard.

7. BRUCE WILLIS WASN’T EVEN THE STUDIO’S THIRD CHOICE FOR THE ROLE.

If Die Hard was to be a success, the studio knew they needed a bona fide action star in the part, so they set about offering it to a seemingly never-ending list of A-listers of the time. Rumor has it that Sylvester Stallone, Harrison Ford, Robert De Niro, Charles Bronson, Nick Nolte, Mel Gibson, Richard Gere, Don Johnson, Burt Reynolds, and Richard Dean Anderson (yes, MacGyver!) were all considered for the role of John McClane. And all declined it.

8. BRUCE WILLIS WAS CONSIDERED A COMEDIC ACTOR AT THE TIME.

Die Hard’s producers had nothing against Bruce Willis, of course. But he wasn’t an immediate choice for the role—up until that point, he was known solely as a comedic actor, not an action star. How times have changed! Following the success of the film, the action genre really became Willis’ bread and butter, and although he has two Emmys for his comedy work, it has remained as such to this day.

9. BRUCE WILLIS WAS BARELY EVEN SEEN ON THE MOVIE’S POSTERS.

Because the studio’s marketing gurus were unconvinced that audiences would pay to see an action movie starring the funny guy from Moonlighting, the original batch of posters for the film centered on Nakatomi Plaza instead of Willis’ mug. As the film gained steam, the marketing materials were altered, and Willis was more prominent in the promos.

10. WILLIS WAS PAID $5 MILLION TO MAKE THE MOVIE.

Even with all the uncertainly surrounding whether he could pull the film off, Willis was paid $5 million to make Die Hard, which was considered a rather hefty sum at the time—a figure reserved for only the top tier of Hollywood talents.

11. WILLIS SUGGESTED THAT BONNIE BEDELIA PLAY HIS WIFE.

Though we suspect that she wasn’t paid $5 million for the gig.

12.  BRUCE WILLIS WAS ABLE TO SAY YES THANKS TO A WELL-TIMED PREGNANCY.

The first few times Bruce Willis was asked to star in the movie, he had to say no because of his commitments to Moonlighting. Then costar Cybill Shepard got pregnant. Because her pregnancy wouldn’t work within the show, producer Glenn Caron gave everyone 11 weeks off, allowing Willis to say yes.

13. SAM NEILL WAS ORIGINALLY APPROACHED FOR THE PART OF HANS GRUBER.

But Neill ended up turning the film down. Then, in the spring of 1987, the casting director saw Alan Rickman playing the dastardly Valmont in a stage production of Dangerous Liaisons and knew they had found their Hans.

14. DIE HARD WAS ALAN RICKMAN’S FEATURE FILM DEBUT.

Though Rickman may have played the part of Hans as cool as the other side of the pillow, it was actually his first role in a feature film.

15. JOHN MCTIERNAN TURNED THE MOVIE DOWN, TOO.

And not just once, but on a few different occasions. His reason was that the material just seemed too dark and cynical for him. “The original screenplay was a grim terrorist movie,” McTiernan recalled to Empire magazine earlier this year. “On my second week working on it, I said, 'Guys, there's no part of terrorism that's fun. Robbers are fun bad guys. Let's make this a date movie.’ And they had the courage to do it.”

16. MCTIERNAN SEES IT AS A SHAKESPEAREAN TALE.

In the original script, the action in Die Hard takes place over a three-day span, but McTiernan—inspired by Shakespeare’s A Midsummer Night’s Dream—insisted that it be condensed into a single evening.

17. NAKATOMI PLAZA IS ACTUALLY FOX PLAZA.

Yes, the corporate headquarters of 20th Century Fox—the very studio making the movie—proved to be the perfect location for the movie’s much-needed Nakatomi Plaza. And as it was still under construction, there wasn’t a whole lot they needed to do to the space to make it movie-ready. The studio charged itself rent to use its own space.

18. THE ROOM WHERE THE HOSTAGES ARE BEING HELD IS LITERALLY SUPPOSED TO BE FRANK LLOYD WRIGHT'S FALLING WATER.

"In this period, Japanese corporations were buying America," production designer Jackson De Govia said in the Die Hard DVD audio commentary. "We posited that ... Nakatami Corporation bought Falling Water, disassembled it, and reassembled it in the atrium, like a trophy."

19. THAT PANORAMIC VIEW OF THE CITY BELOW? IT’S NOT REAL.

A 380-foot-long background painting provided the illusion of a breathtaking city view in the movie. And it was a state-of-the-art one, too, with animated lights, moving traffic, and the ability to change from night to day. The painting is still the property of the studio and has been used in other productions since.

20. THE FILM’S SUCCESS SPAWNED A BONA FIDE FRANCHISE.

In addition to its four sequels, Die Hard has spawned video games and comic books, too.

21. JOHN MCCLANE’S TUMBLE DOWN A VENTILATION SHAFT WAS AN ACCIDENT.

Or maybe “error” would be a better word. But in the scene in which McClane jumps into an elevator shaft, his stunt man was supposed to grab onto the first vent. But he missed. By a lot. Which made the footage even more exciting to watch, so editor Frank J. Urioste kept it in the final cut.

22. ALAN RICKMAN’S DEATH SCENE WAS ALSO PRETTY SCARY.

At least it was for Rickman. In order to make it look as if he was falling off a building, Rickman was supposed to drop 20 feet onto an air bag while holding onto a stunt man. But in order to get a genuinely terrified reaction out of him, they dropped him on the count of two—not three, as was planned.

23. BRUCE WILLIS SUFFERED PERMANENT HEARING LOSS.

In order to get the hyper-realism that director John McTiernan was looking for, the blanks used in the guns in the movie were modified to be extra loud. In one scene, Willis shoots a terrorist through a table, which put the action star in extremely close proximity to the gun—and caused permanent hearing loss. He referenced the injury in a 2007 interview with The Guardian. When they asked Willis his most unappealing habit, he replied that, “Due to an accident on the first Die Hard, I suffer two-thirds partial hearing loss in my left ear and have a tendency to say, ‘Whaaa?’”

24. ALAN RICKMAN WASN’T FOND OF THE NOISE EITHER.

Whenever he had to shoot a gun in the film, Rickman couldn’t help but flinch. Which forced McTiernan to have to cut away from him so that his reactions were not caught on film.

25. GRUBER’S AMERICAN ACCENT POSED NOTHING BUT PROBLEMS.

The scene in which Rickman, as Gruber, slips into an American accent and pretends to be yet another hostage who got away was insisted on by screenwriter Steven de Souza, who wanted them in a room together to duke it out. But McTiernan was never happy with Rickman’s American accent, saying, “I still hear Alan Rickman’s English accent. I was never quite happy with the way he opened his mouth [in that scene] . . . I shot it three times trying to get him to sound more stridently American ... it’s odd for someone who has such enormous verbal skills; he just had terrible trouble getting an American accent.”

26. HANS GRUBER’S GERMAN IS MOSTLY GIBBERISH.

And the bulk of his German cohorts were not German either. Bruce Willis, on the other hand, was actually born in West Germany to an American father and a German mother.

27. BRUCE WILLIS HAS FOUR FEET.

As Willis spends much of the movie in his bare feet running through broken glass, he was given a pair of rubber feet to wear as a safety precaution. Which is great and all, but if you look closely in certain scenes, you can actually see the fake appendages.

28. YOU CAN SEE—BUT NOT TOUCH—JOHN MCCLANE’S SWEATY TANK TOP.

In 2007, Bruce Willis donated the blood-soaked tank top he wore in Die Hard to the National Museum of American History at the Smithsonian.

29. “YIPPEE-KI-YAY” STOLE THE MOVIE.

It was a simple line: “Yippee-ki-yay, motherf*cker!” But it became the film’s defining moment, and the unofficial catchphrase that has been used in all four Die Hard sequels as well.

30. CREDIT FOR THE LINE IS OWED TO WILLIS.

In a 2013 interview with Ryan Seacrest, Bruce Willis admitted that “Yippee-ki-yay, motherf*cker!” was really just a joke. “It was a throwaway,” said Willis. “I was just trying to crack up the crew and I never thought it was going to be allowed to stay in the film."

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

How Experts Say We Should Stop a 'Zombie' Infection: Kill It With Fire
Original image

Scientists are known for being pretty cautious people. But sometimes, even the most careful of us need to burn some things to the ground. Immunologists have proposed a plan to burn large swaths of parkland in an attempt to wipe out disease, as The New York Times reports. They described the problem in the journal Microbiology and Molecular Biology Reviews.

Chronic wasting disease (CWD) is a gruesome infection that’s been destroying deer and elk herds across North America. Like bovine spongiform encephalopathy (BSE, better known as mad cow disease) and Creutzfeldt-Jakob disease, CWD is caused by damaged, contagious little proteins called prions. Although it's been half a century since CWD was first discovered, scientists are still scratching their heads about how it works, how it spreads, and if, like BSE, it could someday infect humans.

Paper co-author Mark Zabel, of the Prion Research Center at Colorado State University, says animals with CWD fade away slowly at first, losing weight and starting to act kind of spacey. But "they’re not hard to pick out at the end stage," he told The New York Times. "They have a vacant stare, they have a stumbling gait, their heads are drooping, their ears are down, you can see thick saliva dripping from their mouths. It’s like a true zombie disease."

CWD has already been spotted in 24 U.S. states. Some herds are already 50 percent infected, and that number is only growing.

Prion illnesses often travel from one infected individual to another, but CWD’s expansion was so rapid that scientists began to suspect it had more than one way of finding new animals to attack.

Sure enough, it did. As it turns out, the CWD prion doesn’t go down with its host-animal ship. Infected animals shed the prion in their urine, feces, and drool. Long after the sick deer has died, others can still contract CWD from the leaves they eat and the grass in which they stand.

As if that’s not bad enough, CWD has another trick up its sleeve: spontaneous generation. That is, it doesn’t take much damage to twist a healthy prion into a zombifying pathogen. The illness just pops up.

There are some treatments, including immersing infected tissue in an ozone bath. But that won't help when the problem is literally smeared across the landscape. "You cannot treat half of the continental United States with ozone," Zabel said.

And so, to combat this many-pronged assault on our wildlife, Zabel and his colleagues are getting aggressive. They recommend a controlled burn of infected areas of national parks in Colorado and Arkansas—a pilot study to determine if fire will be enough.

"If you eliminate the plants that have prions on the surface, that would be a huge step forward," he said. "I really don’t think it’s that crazy."
