For most athletes, winning a medal at the Olympics would be the pinnacle of their career. But these athletes didn't stop at just one. They excelled under pressure and earned themselves a spot in the annals of their respective sports as the Most Decorated Winter Olympians.

1. Ole Einar Bjoerndalen, 13 Medals

Country: Norway
Sport: Biathlon

The 40-year-old won two gold medals at Sochi—in men's sprint biathlon and in the first Olympic mixed relay biathlon—to give him the lead in career-medal count. His hardware collection now includes eight gold medals, four silver, and one bronze. After the latest record-breaking addition, King Harald V of Norway personally congratulated Bjoerndalen.

2. Bjorn Daehlie, 12 Medals

Country: Norway
Sport: Cross-country skiing

When Bjoerndalen won his 13th career medal, he surpassed fellow countrymen Daehlie, who had held the record for most Olympic medals since his dominance in the '90s. Over three Winter Games Daehlie won eight gold and four silver medals before sustaining a career-ending injury as a result of a roller-skiing accident in 1999.

3. Marit Bjørgen, 10 Medals

Country: Norway
Sport: Cross-country skiing

Bjørgen added three gold medals this year to bring her lifetime total up to six golds, three silvers, and one bronze -- making her the most successful female Olympian. After struggling with bronchitis through her first Games in 2006, she became the most decorated athlete at the 2010 Vancouver Games with five medals that year.

4. Raisa Smetanina, 10 Medals

Country: Russia
Sport: Cross-country skiing

Although Bjørgen and Belmondo (#5) have since matched her, Smetanina was the first woman to win 10 Olympic medals. Her final, a gold medal, came at her fifth Olympic Games in Albertville in 1992. She was 39 years old—at that time the oldest woman to win a Winter Olympic gold.

5. Stefania Belmondo, 10 Medals

Country: Italy
Sport: Cross-country skiing

Belmondo's Olympic career spanned a decade—from the 1992 Albertville Games though the 2002 Salt Lake City Games—despite a devastating injury in 1993. She ended her career with two gold medals, three silver, and five bronze.

6. Lyubov Yegorova, 9 Medals

Country: Russia
Sport: Cross-country skiing

Yegorova only made two Olympic appearances: at Albertville in 1992, and two years later at Lillehammer. She managed to squeeze nine medals out of those Games—six gold and three silver—before her career came to an end due to a doping scandal at the 1997 FIS Nordic World Ski Championships.

7. Claudia Pechstein, 9 Medals

Country: Germany
Sport: Speed Skating

Although she left Sochi empty handed, Pechstein can take heart that she is the most successful Olympic speed skater—male or female—in the world, and also the most successful German Winter Olympian of all time. That said, she missed the chance to set herself even further apart in the 2010 Games after getting slapped with a two-year ban from the sport in 2009 for dopping accusations.

8. Sixten Jernberg, 9 Medals

Country: Sweden
Sport: Cross-country skiing

Jernberg (far right) was a blacksmith and a lumberjack before beginning his career as a cross-country skier. Over three Olympics in the 1950s and '60s, he earned four gold, three silver, and two bronze medals, never finishing lower than fifth.

9. Uschi Disl, 9 Medals

Country: Germany
Sport: Biathlon

This five-time Olympian is the owner of two gold medals, four silver and three bronze, and the 2005 title of German Sportswoman of the Year. She has been the most successful women’s biathlete at the Olympic Games, although she never won a gold in an individual event.

10 (tie). Viktor Ahn, 8 Medals

Country: South Korea/Russia
Sport: Speed skating

Several Olympians share the #10 spot, with eight medals each. But Ahn is the only Olympian on this list to have medaled for two different countries. He competed for his home country of South Korea until 2011 when, after a falling out with the South Korean coaches, he became a Russian citizen and started skating for their team. The decision paid off for Ahn. Having failed to qualify with South Korea for the 2010 Olympics, he is leaving Sochi with three gold and one bronze medal and a spot on this list.

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.
