The Bold Van Buren Sisters, Who Blazed a Trail Across America

Descendants of American president Martin Van Buren, Adeline and Augusta Van Buren were born into a life of privilege that assured them the safe and respectable existences of society women. But with America on the brink of war, the sisters ditched their gilded cages for a cross-country adventure they hoped would change their beloved nation for the better.

By July 1916, America was readying to enter World War I, and 32-year-old Augusta and 26-year-old Adeline were eager to do their part as motorcycling military dispatch riders, transporting crucial communications to the front line. Women were flat-out barred from combat duty in the U.S., but as bikers with thousands of hours logged on the roaring vehicles, the Van Burens felt they were uniquely qualified for such arduous and dangerous missions. And they were determined to prove it. By the end of their journey, they would become the first women to travel across the country on two solo motorcycles.

Fittingly, Addie and Gussie—as they preferred to be called—set forth on Independence Day. From Brooklyn's Sheepshead Bay racetrack, they headed to the Lincoln Highway, which ran from Times Square in Manhattan to Lincoln Park in San Francisco. They had top-of-the-line bikes: $275 Indian Power Plus motorcycles that boasted Firestone "non-skid" tires and gas headlights that would allow them to barrel through the darkest nights. They had an indomitable spirit. They had each other. And they'd need all the courage and resources they could muster for this daunting endeavor.

“There were no road maps west of the Mississippi," their great-nephew and historian Robert Van Buren explained to the Worcester, Massachusetts Telegram of the sisters' epic journey. "The roads were just cow passes, dirt trails, wagon trails, things like that.” The Lincoln Highway was far from the paved superhighways of today. Heavy rain proved a major problem, wiping out roads and throwing the Van Burens off-course and off their bikes. “They had no helmets. They just had goggles with a leather cap and leathers on. They were really exposed to the elements,” Van Buren said. “They had a tough time.” Yet weather and murky maps weren't their only obstacles.

Just west of Chicago, the motorcycling mavens were pulled over by police—not for the way they were driving but for the way they were dressed. Though women's fashion was shifting from corsets to more comfy attire, dresses were still the norm. In some states it was actually illegal for women to wear pants. So the Van Burens' military-style leggings and leather riding breeches got them arrested again and again by confounded cops. Between arrests and weather delays, the sisters' one-month journey stretched into two.

By August, Addie and Gussie reached Colorado's Rocky Mountains and earned their first record, becoming the first women to reach the 14,109-foot summit of Pike's Peak by motorized vehicle. Running behind schedule, the sisters abandoned their plan to ride north through Wyoming, favoring a more direct path through the Rockies. Unfortunately, relentless rain transformed the mountains’ dirt paths to sucking mud that mercilessly trapped their tires. Exhausted, freezing, and filthy from their fruitless efforts to free their wheels, the dejected duo was forced to abandon their bikes and seek out help on foot. Hours and miles later, the sisters slid out of the darkness upon the small mining town of Gilman, Colorado. They were quite the sight to the awed miners: two angel-faced ladies draped in leather and caked in mud.

The miners offered them rest and food, then helped the sisters free their bikes. But another brush with disaster came 100 miles west of Salt Lake City, where the winds had whisked away the desert's path, and the pair was woefully low on water. Thankfully, their luck held up again: A prospector came along who not only had a horse-drawn cart packed with supplies, but also a keen sense of direction to get them back on their way.

Exhausted and elated, Addie and Gussie Van Buren reached San Francisco at long last on September 2, having traveled 5500 miles, and completed their journey on September 8 after arriving in Los Angeles. And still, they pressed on, traveling down to the Mexican border and Tijuana.

Their remarkable ride earned headlines, but much of the media coverage disappointed. Leading motorcycle magazines focused on the bikes, not the bikers. Others ignored the purpose and historical import of their journey, publishing puff pieces about the ladies' curious "vacation." Worse yet, The Denver Post accused the sisters of exploiting World War I to abandon their duties at home to "display their feminine counters in nifty khaki and leather uniforms." But most vexing, the U.S. government was unmoved, and rejected the Van Burens' application for dispatch service.

Following their cross-country adventure, the boundary-busting sisters pursued new passions. In a time when female lawyers were unheard of, Addie earned her law degree at prestigious New York University. Meanwhile, Gussie became a pilot, flying in Amelia Earhart's Ninety-Nines, an international organization dedicated to creating a supportive environment and opportunities for aviatrixes. With these accomplishments, each sister added credence to Gussie's famous maxim, "Woman can, if she will."

While their journey didn't deliver the immediate impact the sisters had hoped for, today they are remembered as pioneers for women and motorcyclists alike. Addie and Gussie's courageous spirit and intense independence is celebrated by descendants and admirers who have kept their legacy alive through cross-country rides that traced their path on the trip's 90th and 100th anniversaries. Plus, both the Sturgis Motorcycle Museum's Hall of Fame in South Dakota and the AMA Motorcycle Hall of Fame of Ohio have posthumously inducted the Van Burens as esteemed members.

Both Addie and Gussie enjoyed full lives with careers that thrilled them, and family that loved and still rally around them, decades after their deaths at ages 59 and 75 respectively. In their time, these headstrong and hearty sisters witnessed the passing of the 19th Amendment that gave women the vote. They cheered the female patriots who rushed into the workforce as World War II demanded. They relished in a world that was changing to meet them, the industrious, rebellious, and brave Van Burens.

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!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
