Greatest Hits of '07: The Great Public Restroom Debate

Original image

As we near year's end, we're re-posting a few heavily commented-upon posts from earlier in 2007. Here's one of our favorites, from September. This post also inspired my all-time favorite negative comment (#12).

I've never been in a great public restroom. I was under the impression they were all basically disgusting, with varying levels of nastiness.

Apparently, I've been going in all the wrong places.

Cintas, a company that sells corporate restroom supplies, has been naming America's Best Restrooms since 2001. This year's winner: Jungle Jim's International Market in Fairfield, Ohio.

Considering my grocery store does not have public restrooms, I'm impressed. And that's just the outside.

junglejims.jpg
Here's the America's Best Restroom write-up: "Jungle Jim's International Market is approximately 300,000 square feet of shopping ingenuity - it has Amish food, a cheese shoppe, garden center, international cuisine, cooking classes and eight aisles of pet supplies to name a few. And in the heart of it all, you'll find that Jungle Jim's famous restrooms stop shoppers dead in their tacks. Talk about bathroom humor -- the entrance doors are actual port-o-lets. Unsuspecting shoppers patiently wait their turn until they see three or four people exiting. Upon opening the door they discover a gigantic, modern restroom within. Truly a luxurious port-o-potty - Jungle Jim's style!"

Here are some other bathrooms you'd be lucky to find across the country.

Waffle House of America
Lawrence, Michigan
Fifth Place, 2004
wafflehouse1.jpg"Guests are greeted with soothing piano music and your eyes are quickly drawn to the focal point of the room, a beautiful hand-painted vanity. The bathroom stalls have a crackled paint finish and even the toilet seats are hand painted with roses. A panoramic mural of painted clouds surrounds the stalls to complete the outdoor garden atmosphere. No expensive contractors of decorators turned this bathroom into such a treasure. It was lovingly created with help from craft magazines, Mom and ideas from the Discovery Channel."

Wall City Toilet
Boston, Massachusetts
Third Place, 2004
wallcitytoilet.jpg

"During ten years of development and engineering, Wall's team took onto consideration comfort, hygiene, accessibility, cleanliness and security, as well as quality and design. The result: the world's smallest footprint for a self-cleaning, fully automatic toilet. The ergonomic design and technological conveniences of Wall's automatic public toilet create and amenity that allows all individuals, regardless of disability, to meet their needs in an easy and efficient manner."

Yavneh Day School
Cincinnati, Ohio
Fourth Place, 2003
schoolbathroom.jpg "We used a picket fence/bird house theme. All items were donated by employees. A selection of potpourri , sprays and lotions are arranged on a charming shelf. The idea for the bathroom was from our elementary school principal, Dr. Susan Moore. It has picket fence wallpaper, a shelf with bird houses, a green mirror, flowers, and even a bird house light switch cover!"

Art Chicks
artchicks.JPGLouisville, Nebraska
Second Place, 2004
"The Art Chicks bathroom is always super-dooper clean and has all the things a 'chick' would need - great soap, hand lotion, double ply Charmin Bath tissue, feminine hygiene supplies, hairspray and, of course, a great mirror."

Lee Davis Texaco
Mechanicsville, Virginia
Fifth Place, 2001-02
leedavistexaco.gif "Both the men's and women's restrooms are decorated with a touch of warmth from home. Different from being the gas station type restrooms with plain walls, a sink and a toilet, we want people to feel at home and welcome. There are pictures on the walls and rugs on the floor. The women's bathroom has flowers and the men's bathroom has plants to make them more decorated."

University of Notre Dame, Main Building
South Bend, Indiana
First Place, 2002
notredame.gif"The restrooms in the Main Building have Stovax Victorian tile floors (imported from England). The main door to all restrooms is refinished in their original glory of stained wood. Interior partition doors are finished solid oak mounted to marble finished partitions. Drinking fountains are inside a partitioned portion of the restroom. Faucets on sinks are designer accented with chrome and brass. Counters are built in for diaper changing and/or for luggage/bags. The lighting is classical 1800s style lighting suspended from the ceiling in reflector bowls."

(Any Notre Dame students or alums care to weigh in? Should the bathrooms be on the campus tour?)

This might be a loaded question in light of the Larry Craig scandal, but have you ever had a great experience in a public restroom? Tell us about it, or nominate that john for next year's trophy.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017
Original image
iStock // Ekaterina Minaeva

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!
