Ed. note: If you missed our first post earlier this week on New Amsterdam Records, be sure to check it out here. Part 2 in the mini-series, on Darcy James Argue's Secret Society, can be found this-a-way. Today, we continue with Part 3 by introducing you to another of New Amsterdam's exciting, new artists, Nadia Sirota.

If you live in NYC, or listen to WNYC online, and you are, like me, a night owl who loves to listen to the radio, you probably already know violist Nadia Sirota. She co-hosts Overnight Music, the midnight show on 93.9 FM. While she'll often play new recordings of big, famous symphonies, the best part of the show is when she promotes up-and-comers on the scene, local musicians like those we've been talking about this week in connection with New Amsterdam Records.

Sirota, herself, has a new album out on the label, First Things First, featuring new music by composers Nico Muhly, Marcos Balter, and Judd Greenstein, New Amsterdam co-founder.

Nadia18_3.jpgSirota commissioned nearly all the pieces on the album, including this cool track called entitled "Etude 1A" (there's a second, similar piece later on the CD entitled "Etude "¨1"). For these two pieces (an etude is traditionally a lesson piece, or a study piece) Sirota commissioned composer Nico Muhly. You can't help but hear the Philip Glass influence in"¨ these lovely little pieces, which shouldn't come as a surprise, as Muhly's day job is assisting Glass full-time (one of Muhly's jobs is "¨to feed Glass's manuscripts into a computer program that plays the scores back to the composer).

If you're wondering how she got the viola to sound like an organ, she didn't. That's a computerized organ accompanying her."¨"¨"¨

[Read on for more track excerpts and a short Q&A with Sirota where she unearths the origins of all those nasty viola jokes. Also, be sure to check out our contest at the end of the interview for your chance to win a copy of First Things First.]

While the majority of the tracks on First Things First feature Sirota alone, or with one other instrument, there is one larger work on the album, written by Greenstein, a piece for string quartet called "The Night Gatherers," featuring the Chiara String Quartet.

Pretty Romantic, with a capital R, eh? That's another thing that's so compelling about this debut CD: there's a little bit of everything, in a great, Post-Modern sort of way. Be sure to pick up a copy through New Amsterdam's site, or try for your chance to win a free copy below, after the interview.

Q&A with Nadia Sirota

DI: Talk a little bit about how your relationship with New Amsterdam Records came about and what the process of putting out your first CD with them was like.

NS: I've been thinking of putting a record out on New Amsterdam since the label was founded, a couple years ago, I think, by a few wonderful composers. One of them, Judd Greenstein, I had worked with extensively, and, in fact, is the composer of two of the pieces on this record. Judd and I met at an idyllic music festival in the berkshires in 2004. There were a lot of bourbon-inflected commissions and general contemplations about the classical music infrastructure as it stood. That kind of thing. When I heard about this label, it seemed like the perfect home for the sort of record I wanted to make. New Amsterdam is unique in that it's kind of a cooperative label. It offers the musician pretty complete artistic control and a lot of handy artist services, in addition to a lovely stable of label-mates. The handoff is that the projects are a bit more DIY than they might be on, say, Deutche Grammaphone, or whatever. What's great about that is that I really feel like I poured a ton of me into this album.

DI: What's the best part about having your own radio show?

NS: All the crazy programming I can dream up!

DI: What's the worst part?

NS: Scheduling. Free landing in music is a puzzle. Fitting in radio is a puzzle. I dig it, though!

DI: Some of our readers may know this already, but violists have their own immense category of jokes made about them, a tradition that's existed for decades. What do you know about the origin of this tradition? How does it make you feel when you hear a viola joke? What's the best viola joke you've ever heard?

NS: So yeah. Back in the day, the story goes, the majority of violists were violinists who'd been politely asked to consider another profession. The resulting violists were somewhat less than stellar. Viola jokes inevitably emerged. Most of them are punny, cheap, lewd, that kinda thing. But come to think about it, that's sort of how Jokes go. I'm happy to hear new ones! As for "the best I've ever heard," I don't think any of them really deserve a superlative in print, but here are couple of prime examples of the genre:

How do you know when the stage is level? The violist is drooling out of both sides of his mouth.

What's the difference between a violist an a prostitute? A prostitute knows more positions.


We're giving away a copy of First Things First to one, lucky, random winner. To qualify, you must leave a comment below telling us what your favorite orchestral instrument is, and why. No brownie points if your answer is the viola!

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

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!

8 Common Dog Behaviors, Decoded
May 25, 2017
Original image

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
