According to a Gallup poll, 61 percent of Americans believe John F. Kennedy’s assassination was the result of a conspiracy. Among those who don't think Oswald acted alone, the same names keep popping up. With varying degrees of plausibility, here are nine people and groups who've been blamed for killing Kennedy.

1. Lyndon B. Johnson

A big contributor to this theory is Roger Stone, who wrote The Man Who Killed Kennedy: The Case Against LBJ. Stone is a Washington insider, having worked for Richard Nixon, Ronald Reagan, and George H. W. Bush. Stone believes that Johnson hired hitman Malcolm Wallace to do the dirty work, which explains an allegation that Johnson ducked before any shots were fired. Stone also believes that Johnson confessed to the crime: “Johnson’s mistress of 21 years, Madeleine Duncan Brown, who bore him an illegitimate son, said that Lyndon Johnson told her on the eve of the assassination, ‘After tomorrow I won’t have to deal with those Kennedy SOBs no more.’”

2. The KGB

Ion Mihai Pacepa, who was a general for the secret police of Communist Romania, blames the KGB for orchestrating the assassination in his book, Programmed to Kill: Lee Harvey Oswald, the Soviet KGB, and the Kennedy Assassination. As for how the Soviet security agency got connected with Lee Harvey Oswald, theorists cite Oswald’s residency in the Soviet Union from 1959 to 1962. During this time, Oswald also met and married his Russian wife, Marina. Before the Kennedy assassination, Oswald wrote a letter to his wife that contained the assertion, “I believe that the Embassy will come quickly.” Pacepa believes this note is a piece of evidence that the KGB told Oswald they would take care of his family.

In another theory, the KGB is responsible for the assassination, but Oswald is not. According to JFK assassination expert Bryan Ghent, these theorists suspect that Oswald “was replaced by a Russian agent who looked like him in order to assassinate our president.”

3. Fidel Castro

Theories about Oswald’s connection to Cuba vary in extremity, and some of these theories claim Castro was directly involved in JFK’s death. As for evidence, Oswald was arrested in 1963 for passing out pro-Castro pamphlets for the New Orleans Fair Play for Cuba Committee. The other primary basis for this theory is Oswald’s trip to the Cuban Embassy, around two months before the assassination, where he allegedly had a meltdown because he wasn’t granted a visa.

In 1963, Castro was questioned about JFK’s assassination, but the U.S. government determined he was not involved.

4. Woody Harrelson's Dad

In 1980, Charles Harrelson was convicted of shooting federal judge John H. Wood, Jr. He was arrested in September of that year after a six hour standoff with police on the side of a highway. During the saga, Harrelson confessed to the assassination of John F. Kennedy in addition to Judge Wood. He later stated he had nothing to do with the JFK assassination, claiming he only confessed to the crime to ensure that he would live longer.

5. Secret Service Agent George Hickey

In 1992, Bonar Menninger released his assassination theory in the book Mortal Error: The Shot That Killed JFK. The book details a claim that one of Kennedy’s Secret Service agents, who was riding in the car behind the President, shot Kennedy by accident. Menninger worked with Baltimore ballistics expert Howard Donahue to compile the evidence. Donahue told a magazine, “It is a ballistically unshakable fact that the fatal shot came from a position behind and to the left of the president.” The two theorists concluded that the shooter was agent George Hickey, who reacted to Lee Harvey Oswald’s first shot by shooting his own gun and further injuring JFK.

Hickey did acknowledge the accusation. He sued Menninger after the book was released, but St. Martin’s Press, the publisher of the book, settled.

6. The Central Intelligence Agency

According to author Patrick Nolan, who wrote CIA Rogues and the Killing of the Kennedys, a group of rogue CIA agents killed JFK. Nolan names James Angleton, Richard Helms, E. Howard Hunt, and David Phillips as members of the responsible group. He cites disagreement with Kennedy’s approach to Cuba as the group’s motive.

As for evidence, the most compelling is E. Howard Hunt’s deathbed confession to his family. Hunt, who was also involved in the Watergate Hotel break in, allegedly told his sons that the group of CIA rogues invited him to have a role in the assassination, which was originally supposed to take place in Miami before it was moved to Dallas. His son, Howard St. John Hunt, relayed his father's message to the LA Times, “He told me in no uncertain terms about a plot originating in Miami, to take place in Miami.”

7. Alien Researchers

William Lester’s book, A Celebration of Freedom: JFK and the New Frontier, contains a letter from Kennedy to the CIA dated ten days before the assassination. In the letter, Kennedy requests a “classification review of all UFO intelligence files affecting National Security.” Conspiracy theorists see a connection between this letter and Kennedy’s murder, blaming either a CIA cover-up or another alien research organization.

Lester maintains that the CIA gave him the letter, but government insiders believe the letter is a phony.

8. Carlos Marcello

Lamar Waldron has written multiple books accusing the mafia of killing JFK. He also believes the CIA had a role in covering up the assassination. In his theory, mafia boss Carlos Marcello hired hitmen to assassinate Kennedy because the president and his brother, Attorney General Robert F. Kennedy, were too tough on mob-related crimes. In 1985, Marcello allegedly admitted to the murder. He told a fellow prisoner, “Yeah, I had the son of a bitch killed. I’m glad I did. I’m sorry I couldn’t have done it myself.”

This theory isn’t going away. A November 2013 poll revealed that 13 percent of Americans believe that the mafia is to blame for Kennedy’s assassination. Waldron’s 2008 book about the theory, Legacy of Secrecy, is being adapted into a film starring Leonardo DiCaprio.

9. Joe DiMaggio

Even baseball legend Joe DiMaggio has been blamed for the assassination! According to this theory, DiMaggio was sure that a member of the Kennedy family had Marilyn Monroe killed. DiMaggio’s lawyer Morris Engelberg wrote that the Hall of Famer refused to go to events if there would be members of the Kennedy family there. DiMaggio apparently told Engelberg, “It’s in their blood, and what they did to me will never be forgotten. They murdered the one person I loved.” Even as crazy conspiracy theories go, this one's a little flimsy.

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.
