40 Dandy D-Words To Deepen Your Vocabulary

Original image

It’s thought that the earliest ancestor of our humble letter D was an Ancient Egyptian hieroglyph representing a door, which is where D get its hollowed-out shape from. Over time, that hieroglyph became a Phoenician letter, dalet, which then became the Greek letter delta, and finally the Roman letter D, which arrived in England (along with most of the rest of the modern alphabet) from continental Europe more than 1500 years ago.

Before then, English was written using a runic writing system called futhorc, a number of the letters of which—like thorn (Þ þ) and wynn (Ƿ ƿ)—survived into the Old English period before dying out later. The Old English letter eth(Ð ð), however, effectively went the other way: it was invented in Britain (or perhaps Ireland) after the introduction of the Latin alphabet to England, and is actually a derivative of the Roman letter D. Although it too eventually fell out of use, it still survives in modern-day Icelandic.

Nowadays, D is one of the most frequently used letters of our alphabet, accounting for just over 4 percent of a standard page of English text (or one out of every 25 letters), and roughly 2.5 percent of all the words in a standard dictionary—including the 40 delicious D words listed here…

1. DAB-DUMP

An old Yorkshire dialect word for a pool of water left on the beach after the tide retreats.

2. DABERLICK

Daberlick or dabberlack is an old dialect name for long, straggly seaweed.Figuratively, it can be used as a nickname for greasy, lank hair, or for a tall, gangly person.

3. DABSTER

An astute or especially skilled worker.

4. DAFFLED

If you’re daffled, then you’re bewildered or disorientated by a sensory overload.

5. DANDIE-CLAW

A dandie-claw is an easily completed task or, when used in the phrase, “to give it the dandie-claw,” it essentially means “that won’t last long,” or “that won’t take long to finish off.” No one is quite sure where the phrase comes from, but it’s possible that a dandy or dandie-claw was originally a small brush used to groom horses, which at some point in time might have become synonymous with a brief or undemanding chore.

6. DANDLE

To bounce a baby on your knee is to dandle it.

7. DANG-SWANG

To do something dang-swang is to do it vigorously, or with great energy or enthusiasm.

8. DANGLEMENT

An 18th century word either for a finger, or for a dangling decoration, or trim on a garment. A danglet—literally a “little dangle”—is an icicle.

9. DAPPERPYE

An old adjective meaning “variegated” or “multi-colored.”

10. DAPPERWIT

13. DAYLIGAUN

An old Scots word for twilight, dayligaun literally means “daylight-going.”

14. DEAD-HORSE

As a metaphor for something that has ceased to be useful, the term dead horse is today more often than not used in the phrase “flogging a dead horse,” meaning “to fruitlessly continue with something all interest has been lost in.” Before then, however, dead-horse was a 17th century term for work for which you’d been paid in full in advance—and so to work the dead-horse or for a dead horse meant “to busy yourself in work that at the end of which you won’t be paid.” A dead-man, incidentally, is an old English nickname for an empty liquor bottle, so being down among the dead-men meant “passed out drunk on the floor” in 18th century English.

15. DEAD-NIP

18th century slang for a failed idea.

16. DEAMBULATE

To walk about, or to stray away from home.

17. DECIDOPHOBIA

If you’re decidophobic, then you hate making decisions. Other D phobias include dendrophobia (trees), dromophobia (running, or crossing roads), didaskaleinophobia (school), dipsophobia (alcohol), and doraphobia (animal furs).

18. DEDOLEATE

A 17th century word meaning “to cease to be unhappy.”

21. DEPECULATE

Peculation is an old 17th century legal term for embezzlement—in particular, the embezzlement of funds belonging to a country or head of state. To peculate or depeculate, ultimately, is an old-fashioned word meaning “to steal by peculation,” which was typically used to refer to public officials pilfering state funds for their own personal use.

22. DEPEDITATE

In medical terminology, a depeditation is the amputation of a foot. Thankfully, the relative verb depeditate can simply be used to mean “to be deprived of the use of your feet”—worth remembering next time you go deambulating in a new pair of shoes.

23. DEPROELIATION

Derived from a Latin word meaning “to engage violently in war,” deproeliation is just a 17th century word for a battle.

24. DIABLERIE

The perfect word for Dr. Faustus: diablerie is work or business done with, or for, the Devil. Figuratively, it can mean recklessness or audaciousness, or else any underhand, shady dealing.

25. DIABLOTIN

Borrowed into English from French in the 1800s, a diablotin is a tiny devil or imp. It’s also, because of its unusual appearance, a nickname for the oilbird.

An 18th century nickname for a person’s face (derived from the dial or “face” of a clock).

27. DILLYALL

An old English dialect word for anything owned because it looks nice, not because it’s useful or functional.

28. DILORICATE

29. DIMBER

Dimber was a 17th century word meaning “pretty” or “smart,” while a dimber-damber was the leader or “face” of a gang of rogues or vagabonds.

30. DISCALCEATE

To discalceate is to remove your shoes. Worth remembering once you’ve deambulated and depeditated.

31. DO-NO-BETTER

The slightly less complimentary Edwardian equivalent of "bae"—a do-no-better or do-nae-better was “a sweetheart whom one has to be content with, for want of a better.”

32. DOATY

When your head nods up and down while you’re trying to stay awake? That’s doatying.

33. DOCH-AN-DORRIS

A doch-an-dorris or deochandorus is a “stirrup-cup”—a drink or toast made with, or in honor of, someone about to leave. It derives from an old 17th century Scots Gaelic phrase, deoch an doruis, that literally means “door-drink.”

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
Original image

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.
