Vonnegut's Letter to His Family About His Imprisonment in Slaughterhouse Five

Original image

Kurt Vonnegut Jr.'s most famous novel is Slaughterhouse-Five. You may have read it -- it's taught in many high school English classes in the U.S., though in others it has been banned. So it goes. Anyway, Slaughterhouse-Five is partially autobiographical; it's based partly on Vonnegut's experiences as a Prisoner of War in World War II, when he and other POWs were imprisoned in an underground slaughterhouse meat locker in Dresden in 1944, Germany. By day, they worked in labor camps; at night they slept in the slaughterhouse. During his imprisonment in the slaughterhouse (which was indeed slaughterhouse number five, or Schlachthof Fünf in German), the Allies fire-bombed Dresden, largely destroying it and inflicting mass casualties (estimated at 250,000 by Vonnegut). But Vonnegut survived.

Twenty-five years later, Vonnegut would publish the novel Slaughterhouse-Five, and the rest is history. But what was his frame of mind during the imprisonment? What happened before he ended up in the slaughterhouse? How did he get out of it? The awesome blog Letters of Note publishes a letter Vonnegut wrote to his family from a repatriation camp in France, shortly after his POW experience. Below are some excerpts (emphasis added); read the rest here.

... Well, the supermen marched us, without food, water or sleep to Limberg, a distance of about sixty miles, I think, where we were loaded and locked up, sixty men to each small, unventilated, unheated box car. There were no sanitary accommodations -- the floors were covered with fresh cow dung. There wasn't room for all of us to lie down. Half slept while the other half stood. ...

... Under the Geneva Convention, Officers and Non-commissioned Officers are not obliged to work when taken prisoner. I am, as you know, a Private. One-hundred-and-fifty such minor beings were shipped to a Dresden work camp on January 10th. I was their leader by virtue of the little German I spoke. It was our misfortune to have sadistic and fanatical guards. We were refused medical attention and clothing: We were given long hours at extremely hard labor. Our food ration was two-hundred-and-fifty grams of black bread and one pint of unseasoned potato soup each day. After desperately trying to improve our situation for two months and having been met with bland smiles I told the guards just what I was going to do to them when the Russians came. They beat me up a little. I was fired as group leader. Beatings were very small time: -- one boy starved to death and the SS Troops shot two for stealing food.

... On about February 14th the Americans came over, followed by the R.A.F. their combined labors killed 250,000 people in twenty-four hours and destroyed all of Dresden -- possibly the world's most beautiful city. But not me.

... I've too damned much to say, the rest will have to wait, I can't receive mail here so don't write.

May 29, 1945

Love,

Kurt - Jr.

I urge you to read the whole letter. It's a riveting first-person account of being a POW in WWII, and the wry voice of Vonnegut the novelist was already apparent in his letter. In the same way he repeats "So it goes" in Slaughterhouse-Five, he repeats "But not me" in this letter.

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.
