"Luck of the Irish" is an Old Mining Expression

In time for St. Patrick’s Day, everyone at Wordnik started wondering about the origins of luck-related words.

1. Luck of the Irish

The phrase luck of the Irish is commonly thought to mean “extreme good fortune.” However, according to Edward T. O’Donnell, an Associate Professor of History at Holy Cross College and author of 1001 Things Everyone Should Know About Irish American History, the term has not an Irish origin but “a happier, if not altogether positive,” American one.

"During the gold and silver rush years in the second half of the 19th century, a number of the most famous and successful miners were of Irish and Irish American birth. . . .Over time this association of the Irish with mining fortunes led to the expression 'luck of the Irish.' Of course, it carried with it a certain tone of derision, as if to say, only by sheer luck, as opposed to brains, could these fools succeed."

2. Luck

The word luck is Middle Dutch in origin, coming from luc, a shortening of gheluc, “happiness, good fortune.”

Luck may have been borrowed into English in the 15th century as a gambling term. (Draw an ambsace, or double aces? Then you’re S.O.L.—a phrase which originated as World War I military slang.)

3. Potluck

Potluck, now mostly associated with “a meal consisting of whatever guests have brought,” originally meant “what may chance to be in the pot, in provision for a meal; hence, a meal at which no special preparation has been made for guests.” And while potluck bears a striking resemblance to potlatch, a Native American “feast, often lasting several days,” according to the Word Detective, “there is no actual connection between the words.”

4. Hap

Hap is older than luck. Originating in the 12th century, the word comes from the Old Norse happ, meaning “chance, good luck.” Hap gives us happy, as well as haphazard, “chance; accidental; random”; hapless, “luckless, unfortunate”; and mishap, “misfortune.”

5. Auspicious

Auspicious, “of good omen; betokening success,” comes from the Latin auspicium, “divination by observing the flight of birds.” In ancient Rome, an augur was “a functionary whose duty it was to observe and to interpret, according to traditional rules, the auspices, or reputed natural signs concerning future events.” An auspex was an augur “who interpreted omens derived from the observation of birds.” To auspicate means “to initiate or inaugurate with ceremonies calculated to insure good luck.”

6. Luckdragon

A luckdragon, “a fictitious flying dragon with a wingless elongated body, possessing neither magical talent nor immense physical strength, but distinctive in its unfailing serendipity,” is a meme based on the character from the film, The Neverending Story.

7. Lucky-penny

A lucky-penny is “a small sum given back ‘for luck’ to the purchaser or payer by the person who receives money in a bargain or other transaction,” as well as “a copper tossed overboard ‘for luck.’”

8. Lucky-bag

A lucky-bag is “a receptacle on a man-of-war for all clothes and other articles of private property carelessly left by their owners,” so-called because these articles “were later auctioned off,” says A Sailor’s History of the U.S. Navy, “thereby making those Sailors fortunate enough to obtain new items for relatively little money ‘lucky.’” Another definition of lucky-bag is similar to that of grab bag or goody bag.

9. Prosit

Want to wish someone good luck? Prosit! you might say over drinks. Prosit means “good luck to you,” and comes from the Latin, by way of German, pr?sit, “may it benefit.”

10. Mascot

Or — and this seems particularly appropriate during the NCAA Tournament — you could get your own mascot, “a thing supposed to bring good luck to its possessor; a person whose presence is supposed to be a cause of good fortune.” The word mascot comes from the French mascotte, “sorcerer’s charm,” which ultimately comes from the Medieval Latin masca, “mask, specter, witch.”

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!

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.
