You know that John Lennon, who would have turned 75 years old today, was the leader and founding member of The Beatles. Let's take a look at a few facts you might not have known about him.

1. He was a choir boy and a Boy Scout.

Yes, John Lennon, the great rock 'n' roll rebel and iconoclast, was once a choir boy and a Boy Scout. Lennon began his singing career as a choir boy at St. Peter's Church in Liverpool and was a member of the 3rd Allerton Boy Scout troop.

2. He hated his own voice.

Incredibly, one of the greatest singers in the history of rock music hated his own voice. Lennon did not like the sound of his voice and loved to double-track his records. He would often ask the band's producer, George Martin, to cover the sound of his voice: "Can't you smother it with tomato ketchup or something?"

3. He was dissatisfied with all of The Beatles' records.

Dining with his former producer, George Martin, one night years after the band had split up, Lennon revealed that he'd like to re-record every Beatles song. Completely amazed, Martin asked him, "Even 'Strawberry Fields'?" "Especially 'Strawberry Fields,'" answered Lennon.

4. He was the only Beatle who didn't become a full-time vegetarian.

George Harrison was the first Beatle to go vegetarian; according to most sources, he officially became a vegetarian in 1965. Paul McCartney joined the "veggie" ranks a few years later. Ringo became a vegetarian not so much for spiritual reasons, like Paul and George, but because of health problems. Lennon had toyed with vegetarianism in the 1960s, but he always ended up eating meat, one way or another.

5. He loved to play Monopoly.

During his Beatles days, Lennon was a devout Monopoly player. He had his own Monopoly set and often played in his hotel room or on planes. He liked to stand up when he threw the dice, and he was crazy about the properties Boardwalk and Park Place. He didn't even care if he lost the game, as long as he had Boardwalk and Park Place in his possession.

6. He was the last Beatle to learn how to drive.

Lennon got his driver's license at the age of 24 (on February 15, 1965). He was regarded as a terrible driver by all who knew him. He finally gave up driving after he totaled his Aston-Martin in 1969 on a trip to Scotland with his wife, Yoko Ono; his son, Julian; and Kyoko, Ono's daughter. Lennon needed 17 stitches after the accident.

When they returned to England, Lennon and Ono mounted the wrecked car on a pillar at their home. From then on, Lennon always used a chauffeur or driver.

7. He used to sleep in a coffin.

According to Allan Williams, an early manager for The Beatles, Lennon liked to sleep in an old coffin. Williams had an old, abandoned coffin on the premises of his coffee bar, The Jacaranda. As a gag, Lennon would sometimes nap in it.

8. The last time he saw Paul McCartney was on April 24, 1976.

McCartney was visiting Lennon at his New York apartment. They were watching Saturday Night Live together when producer Lorne Michaels, as a gag, offered the Beatles $3000 to come on the show. Lennon and McCartney almost took a cab to the show as a joke, but decided against it, as they were just too tired. (Too bad! It would have been one of the great moments in television history.)

9. He was originally supposed to sing lead on The Beatles' first single, 1962's "Love Me Do."

Lennon sang lead on a great majority of the early Beatles songs, but Paul McCartney took the lead on their very first one. The lead was originally supposed to be Lennon, but because he had to play the harmonica, the lead was given to McCartney instead.

10. "All you need is love" was the best lyric he ever wrote.

A friend once asked Lennon what was the best lyric he ever wrote. "That's easy," replied Lennon, "All you need is love."

11. The last photographer to snap his picture was Paul Goresh.

Ironically (and sadly), Lennon was signing an album for the person who was to assassinate him a few hours later when he was snapped by amateur photographer Paul Goresh on December 8, 1980.

Lennon obligingly signed a copy of his latest album, Double Fantasy, for Mark David Chapman. Later that same day, Lennon returned from the recording studio and was gunned down by Chapman, the same person for whom he had so kindly signed his autograph.

Morbidly, a photographer sneaked into the morgue and snapped a photo of Lennon's body before it was cremated the day after his assassination. Yoko Ono has never revealed the whereabouts of his ashes or what happened to them.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

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!

What Happened to Jamie and Aurelia From Love Actually?
May 26, 2017

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
