A world without Roald Dahl would be a world without Oompa Loompas, Snozzcumbers, or Muggle-Wumps. And who would ever want to live in a world like that? So today, on what would have been the author and adventurer’s 100th birthday, we celebrate Roald Dahl Day with these 11 gloriumptious facts about the master of edgy kids' books.

1. WRITING WAS NEVER ROALD DAHL’S BEST SUBJECT.

Dahl held onto a school report he had written as a kid, on which his teacher noted: “I have never met anybody who so persistently writes words meaning the exact opposite of what is intended.”

2. MAKING UP NONSENSICAL WORDS WAS PART OF WHAT DAHL DID BEST.

When writing 1982’s The BFG, Dahl created 238 new words for the book’s protagonist, which he dubbed Gobblefunk.

3. HIS FIRST PROFESSION WAS A PILOT.

And not just any pilot: Dahl was a fighter pilot with the Royal Air Force during World War II. And it was a plane crash near Alexandria, Egypt that actually inspired him to begin writing.

4. HE GOT INTO SOME 007 KIND OF STUFF, TOO.

Alongside fellow officers Ian Fleming and David Ogilvy, Dahl supplied intelligence to an MI6 organization known as the British Security Coordination.

5. DAHL’S FIRST PUBLISHED PIECE WAS ACCIDENTAL.

Upon recovering from that plane crash, Dahl was reassigned to Washington, D.C., where he worked as an assistant air attaché. He was approached by author C.S. Forester, who was writing a piece for The Saturday Evening Post and looking to interview someone who had been on the frontlines of the war. Dahl offered to write some notes on his experiences, but when Forester received them he didn’t want to change a word. He submitted Dahl’s notes—originally titled “A Piece of Cake”—to his editor and on August 1, 1942 Roald Dahl officially became a published author. He was paid $1000 for the story, which had been retitled “Shot Down Over Libya” for dramatic effect.

6. HIS FIRST CHILDREN’S BOOK WAS INSPIRED BY THE ROYAL AIR FORCE.

Published in 1942, The Gremlins was about a group of mischievous creatures who tinkered with the RAF’s planes. Though the movie rights were purchased by Walt Disney, a film version never materialized. Dahl would go on to become one of the world’s bestselling fiction authors, with more than 100 million copies of his books published in nearly 50 languages.

7. DAHL READ PLAYBOY FOR THE ARTICLES.

Or at least his own articles. While he’s best known as a children’s author, Dahl was just as prolific in the adult short story sphere. His stories were published in a range of outlets, including Collier’s, Ladies Home Journal, Harper’s, The New Yorker, and Playboy, where his topics of choice included wife-swapping, promiscuity, suicide, and adultery. Several of these stories were published as part of Dahl’s Switch Bitch anthology.

8. QUENTIN TARANTINO ADAPTED DAHL TO THE BIG SCREEN.

One of Dahl’s best-known adult short stories, “Man from the South” (a.k.a. “The Smoker”) was adapted to celluloid three times, twice as part of Alfred Hitchock Presents (once in 1960 with Steve McQueen and Peter Lorre, and again in 1985) and a third time as the final segment in 1995’s film anthology Four Rooms, which Quentin Tarantino directed.

9. DAHL’S OWN ATTEMPTS AT SCREENWRITING WERE NOT AS SUCCESSFUL.

One would think that, with his intriguing background and talent for words, Dahl’s transition from novelist to screenwriter would be easy. But one would be wrong. Dahl was hired to adapt two of Ian Fleming’s novels, the James Bond novel You Only Live Once and the kid-friendly Chitty Chitty Bang Bang; both scripts were completely rewritten. Dahl was also hired to adapt Charlie and the Chocolate Factory for the big screen, but was replaced by David Seltzer when he couldn’t make his deadlines. Dahl was not shy about his criticisms of the finished product, noting his “disappointment” that the film (and its changed title) shifted the story’s emphasis from Charlie to Willy Wonka.

10. DAHL MADE AN IMPORTANT CONTRIBUTION TO THE FIELD OF NEUROSURGERY.

In 1960, Dahl’s four-month-old son Theo’s carriage was struck by a cab driver in New York City, leaving the child suffering from hydrocephalus, a condition that increases fluid in the brain. Dahl became very actively involved in his son’s recovery, and contacted toymaker Stanley Wade for help. Together with Theo’s neurosurgeon, Kenneth Till, the trio developed a shunt that helped to alleviate the condition. It became known as the Wade-Dahl-Till valve.

11. EVEN IN DEATH, DAHL’S SENSE OF HUMOR WAS APPARENT.

Roald Dahl passed away from a blood disease on November 23, 1990 at the age of 74. Per his request, he was buried with all of his favorite things: snooker cues, a bottle of Burgundy, chocolate, HB pencils, and a power saw.

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!

One Bite From This Tick Can Make You Allergic to Meat

We like to believe that there’s no such thing as a bad organism, that every creature must have its place in the world. But ticks are really making that difficult. As if Lyme disease wasn't bad enough, scientists say some ticks carry a pathogen that causes a sudden and dangerous allergy to meat. Yes, meat.

The Lone Star tick (Amblyomma americanum) mostly looks like your average tick, with a tiny head and a big fat behind, except the adult female has a Texas-shaped spot on its back—thus the name.

Unlike other American ticks, the Lone Star feeds on humans at every stage of its life cycle. Even the larvae want our blood. You can’t get Lyme disease from the Lone Star tick, but you can get something even more mysterious: the inability to safely consume a bacon cheeseburger.

"The weird thing about [this reaction] is it can occur within three to 10 or 12 hours, so patients have no idea what prompted their allergic reactions," allergist Ronald Saff, of the Florida State University College of Medicine, told Business Insider.

What prompted them was STARI, or southern tick-associated rash illness. People with STARI may develop a circular rash like the one commonly seen in Lyme disease. They may feel achy, fatigued, and fevered. And their next meal could make them very, very sick.

Saff now sees at least one patient per week with STARI and a sensitivity to galactose-alpha-1, 3-galactose—more commonly known as alpha-gal—a sugar molecule found in mammal tissue like pork, beef, and lamb. Several hours after eating, patients’ immune systems overreact to alpha-gal, with symptoms ranging from an itchy rash to throat swelling.

Even worse, the more times a person is bitten, the more likely it becomes that they will develop this dangerous allergy.

The tick’s range currently covers the southern, eastern, and south-central U.S., but even that is changing. "We expect with warming temperatures, the tick is going to slowly make its way northward and westward and cause more problems than they're already causing," Saff said. We've already seen that occur with the deer ticks that cause Lyme disease, and 2017 is projected to be an especially bad year.

There’s so much we don’t understand about alpha-gal sensitivity. Scientists don’t know why it happens, how to treat it, or if it's permanent. All they can do is advise us to be vigilant and follow basic tick-avoidance practices.
