5 Infamous Female Spies

Original image

Behind every good war are many good women. Using their feminine (and in at least one case masculine) wiles, the following five spies would make James Bond proud.

1. Mata Hari

While Margaretha Geertruida Zelle MacLeod (1876"“1917) may not have caused World War I, she sure as heck kept it going. Having spent time in Java with her husband, Captain Campbell MacLeod, Margaretha returned to Holland and sued for divorce. To make ends meet she took up exotic dancing and the name Mata Hari (meaning "the light of day" in Malay). With her sensual performances becoming the attraction of the major European cities came the men and the gifts for her favors. Many of these favors came from royalty and high-ranking French and German military officers. As World War I progressed, both sides became suspicious that Mata was spying for the other side. The French eventually put her on trial and, although the charges were never proven, Mata Hari was convicted of espionage and was executed by a firing squad on October 15, 1917. Playing the seductress up until the end, Mata refused a blindfold, smiled, and blew a kiss to the firing squad as the fatal shots were fired.

2. Noor Inayat Khan

In 1940, Khan, along with her mother and sister, escaped back to England just before France surrendered to Germany. While in England she joined the Women's Auxiliary Air Force (WAAF), but her ability to speak fluent French soon caught the attention of the Special Operations group and Khan agreed to become a spy. Khan was flown to Le Mans, where she teamed up with other female spies and traveled to Paris. There they joined the French Resistance Prosper Network. Soon after their arrival, the network was infiltrated and many were arrested. Khan
was ordered to return to England, but instead she stayed on and continued to pass information on to England. Eventually she was arrested again and interrogated by the Gestapo. When she refused to speak, she was sent to a prison in Germany and then to the Dachau concentration camp. On September 13, 1944, Khan and three other female British spies were executed by the Nazi SS. In 1949, Khan was posthumously awarded the George Cross.

3. Belle Boyd (aka "La Belle Rebelle")

belle.jpgBorn Isabelle Boyd in Martinsburg, Virginia, in 1844, the beautiful Belle soon became the star attraction in Washington, D.C., social circles prior to the beginning of the Civil War. With the outbreak of the war, she returned to Martinsburg. When the Union soldiers occupied the city, Belle mixed with the officers and soon gathered information on troop movements, which she passed on to the Confederate forces. However, she is probably best known for warning Stonewall Jackson that the Union intended to blow up all the bridges around Martinsburg. With this information, Jackson, with a small number of troops, was able to surprise the Union troops and drive them from the area. In 1864, Confederate president Jefferson Davis asked Belle to carry letters for him to England. The Union Navy captured her ship, but the officer in charge fell in love with Belle and let her escape. The officer, Lieutenant Samuel Harding Jr., after being courtmartialed and discharged from the Navy, traveled to England, where he married Belle. After the war, Boyd toured the United States as an actress under the stage name of La Belle Rebelle.

4. Elizabeth Van Lew

vanlew.jpgCrazy Bet, as she was known, was born in Richmond, Virginia, in 1818 but educated at a Quaker school in Philadelphia. After developing a hatred for slavery, Elizabeth returned to Richmond and freed all her family's slaves. She also went so far as finding where her freed slaves' relatives were and purchased and freed them also. After the Civil War started, Elizabeth asked to visit Union prisoners being held captive in Richmond. The Union prisoners gave her information, which she then passed on to the North. Among the slaves she freed was Mary Elizabeth Bowser, whom Van Lew got a job as a house servant in the home of Jefferson Davis. This allowed Bowser and Van Lew to collect and pass on information directly from the Confederate president's mansion. Elizabeth effectively used the Crazy Bet moniker to make the residents of Richmond think she was mentally ill. She would wear old clothes and bonnets and talk to herself. Because of this, most people thought that her Northern sympathies were just a part of her craziness. After the war, President Grant named Elizabeth the postmaster for Richmond. When the citizens of Richmond found out that Crazy Bet was an act, they shunned her. However, at her death, the state of Massachusetts placed a memorial marker on her grave.

5. Sarah Emma Edmonds (or Was It Frank Thompson?)

sarah-edmonds.jpg

Born in 1841 in New Brunswick, Canada, Sarah ran away from home in her early teens. In order to survive she became an itinerant Bible salesman, by calling herself Frank Thompson and dressing like a man. In 1861, Frank (Sarah) enlisted in the Second Michigan Infantry and over the next two years not only fought in a number of Civil War battles, but also served as a spy for the Union Army. Solders in her unit called Frank "our woman" because of his feminine mannerisms and his extremely small boot size. However, none of her comrades ever figured out that Frank was really Sarah. This boded well for her spying, where she dressed as a young boy serving in Confederate camps, as an immigrant Irish peddler and, most interestingly, as a woman. In 1863, Sarah caught malaria and mental-floss-forbidden-knowledge.jpgdeserted the army out of fear that hospitalization would reveal her true identity. In 1884, though, Sarah applied for and was awarded a veteran's pension in which the secretary of war acknowledged that Sarah was a female soldier who had rendered faithful services to the ranks.

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.
