"Jingle Bells" Was Originally Written for Thanksgiving

Original image

As your family gathers around the piano tomorrow to sing all of your favorite Thanksgiving songs (you know, like Adam Sandler’s “The Thanksgiving Song” and… “The Thanksgiving Song” remix…) don’t forget the most famous Thanksgiving song of all: “Jingle Bells.”

Back in 1850 or 1851, James Lord Pierpont was perhaps enjoying a little holiday cheer at the Simpson Tavern in Medford, Massachusetts, when Medford’s famous sleigh races to neighboring Malden Square inspired him to write a tune. The story goes that Pierpont picked out the song on the piano belonging to the owner of the boarding house attached to the tavern because he wanted something to play for Thanksgiving at his Sunday school class in Boston. The resulting song wasn’t just a hit with the kids; adults loved it so much that the lyrics to “One Horse Open Sleigh” were altered slightly and used for Christmas. The song was published in 1857, when Pierpont was working at a Unitarian Church in Savannah, Georgia.

Another bit of trivia for you: Mr. Pierpont was the uncle of banker John Pierpont Morgan, better known as J.P. Morgan. Despite this, and despite the fact that his famous holiday composition should have made him a millionaire, Pierpont struggled to make ends meet. His son even renewed the copyright on “Jingle Bells” in 1880, 13 years before his father’s death, but it was never enforced enough to produce any real income.

And I was just kidding about “The Thanksgiving Song,” of course. Though lyrics about turkey and Pilgrims aren’t as abundant as tunes for certain other holidays, they’re out there. Here are a couple:

“Over the River and Through the Woods”

They might as well crown Medford, Massachusetts the Thanksgiving capital of the United States, because the song “Over the River and Through the Woods” was born there too. Lydia Maria Child wrote the poem “A Boy’s Thanksgiving Day” about a trip to her grandfather’s house, which, yes, really does sit near the Mystic River in Medford, Massachusetts. It’s still there today, owned by Tufts University and used as a home for Tufts dignitaries (needless to say, Grandfather had a pretty nice house). The poem was later set to music and became the classic we know today.

"Alice’s Restaurant Massacre"

It doesn’t have much to do with Thanksgiving, except that the real-life events that inspired the song took place on Thanksgiving. After dumping some litter illegally on Turkey Day in 1967, Arlo Guthrie was arrested. When he later went to the induction center to find out about his draft status, Guthrie realized that he had been declared ineligible for the draft due to his lack of moral conduct. The song, which is 18+ minutes long, became a huge hit amongst war and draft protesters.

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!

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.
