Walking the walk for breast cancer

Original image

I don't know what people with other diseases do to cope, but those who've been affected by breast cancer -- they walk. A close relative of mine is a survivor, and last weekend my wife did the San Diego Breast Cancer 3-Day Walk in her honor. It ain't no walk in the park, neither: you walk 20 miles a day for three days, camp in tents at night and there are hills a-plenty. (But hey, blisters don't need chemo. Hence one of the 3-Day's official rules: "no whining!") As someone who maybe walks 60 miles in a year, I was truly humbled watching 4,500+ women (and a few valiant dudes) walk, and sometimes hobble, across the finish line, many overcome with emotion, having collectively raised $12.3 million for breast cancer research. Today I'm sharing some of my photos from the event, along with some facts about breast cancer.

"¢ Women in the United States have a 1 in 8 chance of developing breast cancer during their lifetime, and a 1 in 33 chance of dying from it.
"¢ The patron saint of breast cancer is Saint Agatha of Sicily.
"¢ William Stewart Halsted pioneered the mastectomy in 1882. His procedure, which became known as the Halsted Radical Mastectomy, was performed regularly into the 1970s.

From the great history of breast cancer, Bathsheba's Breast:

In 1967, an Italian surgeon touring Amsterdam's Rijks museum stopped in front of Rembrandt's Bathsheba at Her Bath, on loan from the Louvre, and noticed an asymmetry to Bathsheba's left breast; it seemed distended, swollen near the armpit, discolored, and marked with a distinctive pitting. With a little research, the physician learned that Rembrandt's model, his mistress Hendrickje Stoffels, later died after a long illness, and he conjectured in a celebrated article for an Italian medical journal that the cause of her death was almost certainly breast cancer.

A horror known to every culture in every age, breast cancer has been responsible for the deaths of 25 million women throughout history. An Egyptian physician writing 3,500 years ago concluded that there was no treatment for the disease. Later surgeons recommended excising the tumor or, in extreme cases, the entire breast. This was the treatment advocated by the court physician to sixth-century Byzantine empress Theodora, the wife of Justinian, though she chose to die in pain rather than lose her breast. Only in the past few decades has treatment advanced beyond disfiguring surgery.

There was plenty of support along the way. My favorite sign, which I neglected to get a photo of, read "Stop the war in my rack!"

Once known as "nun's disease" and widely considered a death sentence, today there are more than two million survivors of breast cancer living in the United States. Despite this good news, the number of cases of breast cancer -- especially in the Western world -- has been on the rise since the 1970s.

As the walk drew to a close, participants raised their worn-out shoes in a show of solidarity and respect for the survivors among them.

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!

What Happened to Jamie and Aurelia From Love Actually?
May 26, 2017

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
