World Record Garden Produce

Original image

I picked the very first ripe tomato from my garden yesterday. It wasn't even big enough to cover a sandwich with a slice. There are much larger green tomatoes that will, whenever they ripen. But they are all small potatoes (so to speak) compared to the monsters that some serious gardeners grow. I'm talking about the biggest vegetables ever.

Prolific Cabbage Patch

The growing season is short in Alaska, so vegetables must grow as fast as they can. Steve Hubacek worked for 14 years to get his cabbages to grow very fast -and it worked. He entered a 125-pound cabbage in the "green cabbage" category at the Alaska State Fair in 2009, and not only won, but set a world record for the biggest cabbage. Then two days later, he brought out the big guns, er cabbage. The vegetable he called "The Beast" was entered in the annual Giant Cabbage Weigh-Off and recorded at 127 pounds, which broke his own record. Hubacek said the biggest cabbages don't taste so good, so the Beast was eventually made into compost to feed this year's crop.

Deep Roots

The world's longest carrot measured over 19 feet! Gardener Joe Atherton of Nottinghamshire, England, grows his carrots in plastic tubes, filled with a compost mix, set at a 45 degree angle, with watering holes placed at precise spots for maximum nutrition and drainage. One of his many tubes produced the record-setting root in 2007, after 14 months of growth.

When Life Gives you Lemons

In 2003, Aharon Shemoel grew a lemon that weighed 11 pounds, 9.7 ounces in his orchard at Kefar Zeitim, Israel. It appears to be a conjoined twin.

What a Melon!

The Lloyd Bright family grew a watermelon in 2005 that weighed 268.8 pounds, enough to feed an entire reunion. The Bright farm of Hope, Arkansas had already set two previous records for watermelons.

Digging Taters

The Year of the Potato was celebrated in 2008, so it was only appropriate that a record would be set. Khalil Semhat, a farmer in Tyre, Labanon dug up a potato that required help from a friend just to get it out of the ground. The huge tuber weighed 24.9 pounds! However, there were questions raised as to whether this was a potato or a sweet potato. Sweet potatoes grow much larger, and the world record sweet potato was an 81 pounder grown by Manuel Pérez Pérez of Spain in 2004.

The Guinness folks determined that the Lebanese potato was a sweet potato, and did not break the potato record, which had been held for ten years previously by Nigel Kermode. Kermode grew a 7 pound, 13 ounce spud on the Isle on Man in 1998.

The Great Pumpkin

The world record for the biggest pumpkin is broken almost every year as gardeners compete in contests all over. The current record is held by high school math teacher Christy Harp, who brought a 1,725 pound monster pumpkin to the Ohio Valley Giant Pumpkin Growers annual weigh-off in October of 2009.

Disney's "Tomato Tree"

A tomato vine growing in a greenhouse at The Land pavilion at Epcot Center produces up to 32,000 tomatoes a year! The tomatoes aren't all that big, but the combined weight of that many is over a thousand pounds. Disney agricultural scientist Yong Huang found the tomato variety in a laboratory in China and brought back the seeds to Florida. The huge vine has an extensive support matrix to allow it room to grow and spread and the enclosed greenhouse provides sunlight and temperature control for continuous growth. And Disney isn't telling the rest of the "tree's" secrets.

Tomato in the Cantaloupes

Gordon Graham experimented with his tomato plants in 1986. He figured a really big vine grown before the fruit set would be advantageous for larger fruit. One of Graham's vines grew to almost 14 feet when a storm blew it off its supports and into the cantaloupe patch. At that point, the gardener gave up on the vine and turned his attention to other plants. But the huge vine kept growing, more than tripling in length. Hidden among the cantaloupes, one tomato grew unnoticed until it reached gigantic proportions. Graham eventually saw the big tomato, which weighed seven pounds, 12 ounces when it was finally picked -a world record tomato!

The tomato was ultimately sliced into 21 sandwich slabs and eaten. The Miracle Gro company had a replica made with the same dimensions as the original and presented it to Graham as a record of the... record. Miracle Gro offers a cash prize to anyone growing a bigger tomato, but no one has been able to beat Graham's record yet.

With the new crops coming in and fair season underway, some of these records may be broken soon..

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

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.
