The Story Behind the Peculiar Poem in NYC's Port Authority Tunnel

Actually, the poem is posted in the corridor between the Port Authority subway station and the Times Square subway station. Each line of the poem occupies its own six-inch tall panel affixed to the support beams in the ceiling of the underground, tiled tunnel. As swarms of city-dwellers make their morning and evening trek between the high-traffic subway stations, they need only to glance up to see a sympathetic message.

Overslept.
So tired.
If late,
Get fired.
Why bother?
Why the pain?
Just go home.
Do it again.

A final panel shows a black and white photo of an empty, rumpled bed.

The poem, by Norman B. Colp, is aptly titled "The Commuter's Lament" or, perhaps more cryptically, "A Close Shave." The alternate title is a reference to the Burma-Shave ads of the mid-20th century, which employed a similar style of a series of one-line signs drivers would read as they sped past. Colp told the New York Times he was inspired by the highways out west that he and a girlfriend used to drive along in the '60s where the Burma-Shave billboards were prevalent.

Colp, a native New Yorker who passed away in 2007, was known as an artist and photographer for his witty installations. He was commissioned to create a piece in 1991 as part of the MTA's Arts for Transit, a program started in 1986 which dedicated 0.5 to 1 percent of a station’s rehabilitation budget to bring museum-worthy artwork into the otherwise-utilitarian public transportation system. Colp was paid $5000 for the sardonic piece.

The poem was originally intended as a one-year display, but the MTA chose to leave it up ever since, allowing it to join the ranks of permanent art installations throughout the subway system. The final panel with the slept-in bed went missing after a 2005 station renovation but was reinstalled two years later.

In 2011, two optimistic young college students in the area set out to change the tone of the poem. Feeling that Colp's original work was too pessimistic, the pair of 20-year-olds took it upon themselves to brighten some of the lines—“Overslept” became “Overexcited,” “So Tired” became “Energized.”

The artist's widow, Marsha Stern-Colp, did not appreciate the amendments, saying at the time, “Why be optimistic in these times? Be realistic—life sucks. You get through it the best you can.”

Whether or not that's true, she conceded that what Colp had originally intended to project was not quite as bleak. “His empathy for the overtired, overworked populace trudging to get to work was what it was all about."

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!

Creative Bar Owners in India Build Maze to Skirt New Liquor Laws
June 20, 2017

Facing a complicated legal maze, a bar in the southern Indian state of Kerala decided to construct a real one to stay in business, according to The Times of India. Aiswarya Bar, a watering hole that sits around 500 feet from a national highway, was threatened in 2016 after India's Supreme Court banned alcohol sales within 1640 feet of state and country-wide expressways to curb drunk driving. Instead of moving or ceasing operation, Aiswarya Bar's proprietors got creative: They used prefabricated concrete to construct a convoluted pathway outside the entrance, which more than tripled the distance from car to bar.

Aiswarya Bar's unorthodox solution technically adhered to the law, so members of the State Excise Administration—which regulates commodities including alcohol—initially seemed to accept the plan.

"We do [not] measure the aerial distance but only the walking distance," a representative told The Times of India. "However, they will be fined for altering the entrance."

Follow-up reports, though, indicate that the bar isn't in the clear quite yet. Other officials reportedly want to measure the distance between the bar and the highway, and not the length of the road to the bar itself.

Amid all the bureaucratic drama, Aiswarya Bar has gained global fame for both metaphorically and literally circumnavigating the law. But as a whole, liquor-serving establishments in India are facing tough times: As Quartz reports, the alcohol ban—which ordered bars, hotels, and pubs along highways to cancel their liquor licenses by April 1, 2017—has resulted in heavy financial losses, and the estimated loss of over 1 million jobs. Aiswarya Bar's owner, who until recently operated as many as nine local bars, is just one of many afflicted entrepreneurs.

Some state governments, which receive a large portion of their total revenue from liquor sales, are now attempting to downgrade the status of their state and national highways. To continue selling liquor in roadside establishments, they're rechristening thoroughfares as "urban roads," "district roads," and "local authority roads." So far, the jury's still out on whether Kerala—the notoriously heavy-drinking state in which Aiswarya Bar is located—will become one of them.
