The Late Movies: "Billie Jean" Twelve Ways

Original image

When I came across an amazing* acoustic cover of Michael Jackon's "Billie Jean" performed by Chris Cornell (of Soundgarden and Audioslave), I thought it would be fun to locate a dozen versions. "Billie Jean" was released as a single on January 2, 1983 -- hard to believe that it and the whole Thriller album will turn 30 next year. (Fun fact: the first cassette I ever owned was Thriller, and I got it sometime in 1983.)

The Wikipedia page on this song is well worth a read -- the video for "Billie Jean" was a major milestone for black artists on MTV, and a huge career milestone for Jackson. Read up or listen in:

Chris Cornell (acoustic, live)

Whoa. (* = "Amazing" means I don't really know how to parse this cover. Parts of it seem frankly brilliant (the quasi-Western take on the song that seems to recontextualize it), but it seems to get old about halfway through. There is some level of amazingness that this singer would attempt this song at all, and succeed at all.)

Sungja Jung (acoustic, live, instrumental)

I'd never heard of this South Korean guitarist before stumbling across this clip. Apparently he was 12 at the time of this performance. He performs a complete arrangement of the song (including lead lines and percussion) by himself, live. Utterly amazing. For a grownup guitarist's rendition, check out Adam Rafferty doing something similar.

Jeff Clark (acoustic, live)

Part of a radio contest. Quite a bit more uptempo than Cornell's version. This guy's got a nice high register.

Duwende (a capella)

Hey, it's a video song! This group has done an a capella cover album featuring Michael Jackson songs -- don't miss their version of Human Nature."

Ball in the House (a capella, live)

The audience is eating this up.

Aloe Blacc & The Grand Scheme

A sultry, slowed-down version. Beautiful.

Coldplay

Points for including a mandolin.

Crocz (chiptunes/8-bit)

Imagine "Billie Jean" as a Nintendo soundtrack. Okay, don't imagine, just listen.

Bruno Mars (live)

A medley/mashup of "Smells Like Teen Spirit" (Nirvana), "Billie Jean," and "Seven Nation Army" (The White Stripes). Wow.

Krezip (live)

Apparently this Dutch group played this at their last concert. Jazzy.

Jose Feliciano (live)

Frenetic and fun. There are some video/audio sync issues here.

Amanda Palmer (live)

Performed on the day Michael Jackson died. You can also check out a longer version with an intro.

Got a Favorite Cover?

Post it in the comments. I'm telling you, YouTube is full of "Billie Jean" covers.

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!

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

Opening Ceremony

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.
