The Internet's Famousest Felines

One of the most striking things about the internet boom and the rise of sites like Youtube is the democratization of fame (or "fame" -- there's certainly a difference between reality show famous and Tom Cruise famous) -- but many of those it's brought fame to aren't even human. They're cats. Of the top twenty or so most-watched-ever videos on Youtube -- ranging from about 5 million views on the low end to 40 million on the top end -- eight of them feature cats. Can you imagine twenty million people watching your pet do silly tricks? It boggles the mind! I had to find out what these cats were doing that so many people found irresistible.

Ninja Cat

This is no ordinary video of a cat stalking its owner -- it's shot, and I must say performed, with true Hitchcockian flair. And the music cues -- genius!

Garfield is Real

This is not unlike one of those bigfoot hoax videos, where some unsuspecting hiker with a video camera stumbles across the cryptozoological find of his life. Except in this case, what the camera finds is an honest-to-God real-life Garfield. Watch it through to the end -- the profile shot is the money shot.

Cat Speaking in Tongues?

More than eleven million people have watched this video, which I have to say documents one of the strangest vocalizations I've ever heard from a cat. Kinda reminds me of those 50s-era experiments where they give cats LSD and watch what happens. The canned laugh track makes it all the more surreal.

Spaghetti Cat

With Spaghetti Cat, I think we're witnessing the birth of yet another cat-related meme -- which amazingly, started on television and not the internet. Here's what happened. During a segment of The Morning Show with Mike and Juliet about binge drinking, the image suddenly cuts to a still picture of a cat eating spaghetti -- and then back to the show a second later, with no mention of the cat ever made. It became something of a mystery for weeks afterward, until an E! spokesperson finally revealed that the cat picture had been used as a kind of "visual bleep" (to cover what, we may never know). Regardless of its intent, those in the know are expecting Spaghetti Cat to become the new Rickroll. Here's the clip:

The two talking cats

A simple title, a simple concept, simple execution -- fourteen million views and counting. It's two cats sitting next to one another, who seem to be having a conversation. You've got to wonder, is this a phenomenon so rare, so unheard of, that to capture it on video and post it on the internet could warrant so much attention? Decide for yourself!

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:

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.
