It was the spring of 1862, and Robert Smalls—a 23-year-old enslaved man living in Charleston, South Carolina—was desperate to buy the freedom of his wife and children. The asking price was $800.

He had money saved up. Since the age of 12, Smalls had worked odd jobs in Charleston: lamplighter, rigger, waiter, stevedore foreman. At around age 15, he had found work on the city’s docks and joined the crew of the ship CSS Planter. For every $15 he earned, Smalls was allowed to keep $1. The rest of the money went to his owner.

Smalls tried earning extra cash on the side, buying candy and tobacco and reselling it at a higher price. But it was hardly enough. When he asked to buy the freedom of his wife and children, he barely had $100 to his name. He knew, at that rate, the task could take him decades. Smalls had to think of something new—something drastic.

An unwitting bystander might have mistaken Robert Smalls and his wife Hannah Jones for freed slaves. The couple had met when Robert was 16, working at a hotel where Hannah was employed as a maid. They married, had two children, and lived in a private apartment above a horse stable in Charleston. Each day, Robert walked alone to the docks and wharves of Charleston, eventually finding himself work on the CSS Planter.

But appearances of freedom were an illusion. Smalls and Jones had to give nearly all of their income to his owner. Worse yet, the couple was constantly burdened with worry. Smalls knew that his wife and children could be stripped from his life on his owner’s whim. He knew the only way to keep his family together was to buy them.

Born in 1839 behind John McKee’s house, Smalls had grown up as the family’s household favorite (potentially because McKee, or McKee’s son, was his secret father). Whatever the reason, Smalls did relatively limited housework, was allowed inside his owner’s house, and was permitted to play with the local white children.

Smalls’s mother watched her son being coddled and was afraid he’d grow up without knowing about the horrors of slavery, so when Smalls was 10, she dragged her son into the fields. He picked cotton, rice, and tobacco. He slept on dirt floors. He watched slaves in town be tied to a whipping post and lashed. The experience changed him.

Smalls began to rebel. He protested slavery and started appearing more frequently in jail. Eventually, his mother grew concerned for his safety and asked McKee if Smalls could be sent to Charleston to work. Their owner agreed. It was in Charleston that Smalls would discover the woman who became his wife, as well as a talent for sailing.

By the spring of 1862, Smalls was working aboard the CSS Planter, an old cotton steamer-turned-warship. It was the midst of the Civil War, and Smalls helped steer the boat, plant sea mines, and deliver ammunition and supplies to Confederate outposts along the coast. Whenever Smalls looked out toward sea, he saw a blockade of Union ships bobbing on the horizon.

The captain of the CSS Planter, C.J. Relyea—known for wearing a trademark wide-brimmed straw hat—had a crew comprised of multiple slaves. One day, another enslaved crew member grabbed the captain's hat while he was away and planted it on Smalls’s head. “Boy, you look just like the captain,” he said.

Smalls looked out at the ocean, past Fort Sumter and toward the fleet of Union ships in the distance.

He had an idea.

Smalls knew he could steal the Planter. He knew the shipping routes. He knew the checkpoints. He knew the codes and signals to get past the forts. And, of course, he knew how to pilot the boat. As the Planter’s wheelman, Smalls was basically the boat’s unofficial captain.

Late on May 13, 1862, the Planter returned to Charleston from a two-week trip. The white crewmembers were supposed to stay aboard after docking, but the Planter was scheduled to begin another long mission the next morning, and the white crew supposedly missed carousing and sleeping on land. They left the boat for a night out on the town, trusting the enslaved crew would take care of the ship.

It was exactly what Smalls had hoped for.

Around midnight, Robert slipped the skipper’s jacket over his shoulders and ordered the other enslaved crewmembers to light the boilers. At 2 a.m., the CSS Planter eased into Charleston Harbor.

Smalls quietly directed the boat to a rendezvous point where he picked up Hannah, his children, and eight other enslaved people (Smalls had warned his family in advance of the possibility that May 13 could be the fateful night). Hannah later told a reporter that, in his words, “The whole party had solemnly agreed in advance that if pursued, and without hope of escape, the ship would be scuttled and sunk; and … they should all take hands, husband and wife, brother and sister, and jump overboard and perish together.” Her husband was more terse. When she asked what would happen if they were caught, Smalls said, “I shall be shot.”

The crew intended to fight to the death. The boat was loaded with 200 rounds of ammunition and five large guns, including a howitzer and a giant pivot gun. If cornered, they’d dynamite the boiler.

Moonlight glinted off the water. Smalls raised the Confederate and Palmetto flags and pointed the boat at the open ocean. As the Planter approached the first checkpoint, Fort Johnson, Smalls began to pray, “Oh Lord, we entrust ourselves into thy hands.” He sounded a signal on the steam whistle and was waved through. The boat slipped deeper into the harbor.

As the boat approached Fort Sumter, Smalls adjusted the captain’s straw hat and leaned out the pilot-house window. He had watched Captain Relyea pass the fort dozens of times before. He had studied his body language. So Smalls stood on the deck, arms crossed, his face obscured by the hat’s brim and the night’s darkness.

At 4:15 a.m., the Planter sounded the steam whistle again. According to a report filed by the Committee on Naval Affairs, “The signal ... was blown as coolly as if General Ripley [the commander of Charleston’s defense] was on board.”

The guards at Fort Sumter sounded their signal in return: “All right.”

The Planter successfully passed five Confederate gun batteries. Once outside of Fort Sumter’s cannon range, Smalls lowered the rebel flag and raised a white bed sheet. The Planter aimed for the Union blockade.

Seeing a Confederate ship hurtle in their direction, sailors aboard the union USS Onward panicked. It was dusky, and they couldn’t see the surrender flag.

“Open her ports!” Acting Volunteer Lt. J Frederick Nickels ordered. The crew pointed the No. 3 port gun in the direction of the Planter and was ready to fire when somebody aboard cried, “I see something that looks like a white flag!”

The command to fire was dropped. The group aboard the Planter began to dance and sing. As the Planter reached the blockade, Smalls stepped forward and removed his hat. “Good morning, sir!” he yelled. “I’ve brought you some of the old United States guns, sir!”

Within minutes, the stars and stripes were flapping high from the Planter’s mast.

Smalls quickly became a folk hero. “If each one of the Generals in our army had displayed as much coolness and courage as [Smalls] did when he saluted the Rebel flag and steamed past the Rebel fort, by this time the Rebellion would have been among the things that were [past],” The New York Daily Tribune wrote. Navy Admiral S.F. Dupont would call Smalls “superior to any who have come into our lines.”

Meanwhile, in South Carolina, a $4000 bounty was placed on Smalls’s head and Captain Relyea was court-martialed, sentenced to three months in prison for negligence (although this was later overturned). The Confederate brass was dumbstruck. They couldn’t fathom that a crew of slaves was clever enough to outfox their navy. (Unable to give the credit, F.G. Ravenel, a Confederate Aide-de-Camp, believed that “two white men and a white woman” must have conspired to make it happen.)

Smalls didn’t care. He was too busy enjoying the freedom and money that he had long been denied. A few weeks after surrendering the ship, the U.S. Congress awarded Smalls and his crew half of the Planter’s value. Smalls received $1500 and an audience with President Lincoln.

At one meeting with Lincoln, Smalls was joined by Frederick Douglass. The famed abolitionist implored the president to allow African-Americans to join the military—and convinced him that Smalls should lead the cause.

Smalls did. He joined the U.S. Navy, revealing the location of enemy mines, and personally recruited about 5000 African-American soldiers. He joined the USS Planter on missions to the south, including an attack on Fort Sumter. During a battle at Folly Island Creek, South Carolina, the Planter’s white captain abandoned his post in despair. Smalls stepped into the pilot-house and led the ship to safety. For his bravery, he was awarded the rank of Navy Captain.

When he wasn’t fighting battles at sea, Smalls was fighting civil rights battles on land. In December 1864, Smalls was tossed out of an all-white streetcar in Philadelphia. Enraged, he used his budding fame to protest the segregation of public transit. Three years later, the streetcars of Philadelphia were integrated.

After the war, Smalls returned to South Carolina with the money he earned and bought his former owner's house.

Not one to rest on his laurels, Smalls helped establish a local school board in Beaufort County and one of the first schools for black children in the region. Then he opened a store. In 1868, he ran for—and won—a seat in the South Carolina House of Representatives, then two years later in the state Senate. In 1872, he started a newspaper called The Southern Standard. And in 1874, he ran to become a representative in the U.S. Congress.

He won 80 percent of the vote.

During five nonconsecutive terms, Congressman Smalls pushed for legislation to desegregate the military and restaurants in Washington D.C. His work successfully led to the opening of the famous South Carolina marine base at Parris Island.

All that time, Smalls kept his mind and heart open. Legend has it that when his former owner’s wife was stricken with dementia, she’d often wander into his house, believing it was still hers. Rather than send her packing, Smalls invited her inside.

In 1915, Robert Smalls died in the same house. Today, it’s a National Historic Landmark.

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.
