Man takes Car on 2,000 Mile Test Drive

There's a fine line between "test drive" and "auto theft", but a man in Australia was way over the line. He convinced a car dealer in Melbourne to let him drive a Honda Accord worth $37,000. He took the car on a 3,200 kilometer trip before he was arrested six days later near the town of Tennant Creek, deep in the outback. This is the longest test drive ever known to Australian police.

One-legged Chicken Receives Cancer Treatment150_petchicken.jpg

Eve, a hen in Worcestershire, had a leg amputated 18 months ago due to cancer. Now she has undergone surgery to remove a tumor from her remaining leg, at a cost of over £1,000. Owner Elaine Denney said money is not an issue.

"I wouldn't put Eve through it if I didn't think she still would have quality of life and if I thought she would suffer too much during the treatment."

Beijing is #1 in Public Toilets

The Xinhua news agency reports that Beijing has 5,174 public toilets, the most of any city in the world. The information came from Lu Haijun, director of the Beijing Municipal Administration Commission. New York, London, and Tokyo all have fewer public toilets.

Centenarian to run London Marathon

150_buster.jpg101-year-old Buster Martin is set to compete in the London Marathon on April 13th.

Working plumber Buster Martin ran Sunday's Roding Valley half marathon in Essex in five hours 13 minutes, and is now focusing on London's 26-mile event.

On finishing the run, the first words of the ex-member of rock band The Zimmers were: "Where's my beer?"

You Can't Die, the Cemetery is Full

Mayor Gerard Lalanne of the French village of Sarpourenx told the 260 residents that they were forbidden to die because the parish cemetery was full. An administrative court had ruled against the parish in their bid to expand the cemetery.

"Offenders will be severely punished."

One wonders what kind of severe punishment could be bestowed upon someone who dies against orders.

Big Breasts Handy in Court125_Kozakura.jpg

Last year, 38-year-old model Serena Kozakura was convicted of property destruction after entering a man's room. During an appeal of the verdict, her lawyer argued that her size 44 breasts would have made it impossible for her to squeeze through the hole that was kicked in the door. Tokyo High Court presiding judge Kunio Harada overturned Kozakura's guilty verdict, citing reasonable doubt.

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!

What Happened to Jamie and Aurelia From Love Actually?

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.
