Amusingly Mistranslated Signs From Around the World

Original image

If you've ever been to a restaurant in Greece, chances are you've seen lamp on the menu. The spelling mistake is about as ubiquitous as nude sunbathers on the beach in Mykonos. It's less likely, however, that you've seen my favorite mistranslated sign at Delphi, which reads: "No introducing animals and food on the path." (Banana, meet my daschund Petey. Petey, this is banana"¦)

I've had the good fortune of capturing some great mistranslations over the years as I've traveled, and the even greater fortune of unearthing even more gems on Flickr. Enjoy.

Jesus is said to have walked on water at this, the Sea of Galilee. I guess that was before the municipality of Tiberias erected this sign.

If you crack the code, and open the hidden safe, you don't even want to know what's in store! (via Ben Beiske)

Rumor is, triping will be a new category in the next Olympics. Part drunken stupor, part obstacle course, the new sport is already very popular in small villages in China. (via brytness)

When in Ethiopia, probably best to avoid this restaurant... (via joshua tuggle)

On the other hand, I bet using this bathroom in Deqin, Yunnan, China is a unique experience. (via Timmok)

Never understood what this Jerusalem church has against married folk, but you have to love the photo for the mistranslation, AND the spelling mistake, AND the grammar, AND the artwork.

This one speaks for itself... from a small hotel in Israel.

And just to come full-circle, here's a variation of the Delphi sign found at the Acropolis. Not as amusing, but still cute.

What's your favorite mistranslated sign? In what part of the world did you find it?

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!
