The Late Movies: The Hanks

Original image

Summer's got me feeling like a southern boy stuck in a Yankee's body. All I wanna do is drink bourbon, eat barbecue and listen to the Hanks, by which I mean Hank Williams, one of the most iconic figures in country music, who set the agenda for the genre for years to come; his son Hank Williams Jr., whose exposure of mainstream audiences (all together now: "Are you ready for some football?!") aided country's rise as a major musical and cultural force; and his grandson Hank Williams III, whose heavy metal tendencies and prominence as a performer of neotraditional country in an era dominated by pop country has kept the genre from sliding off the deep end completely in recent years.

If you're in Philadelphia, just follow the scent of booze and pork to my place and we'll have a great time. If you can't join us, you can at least enjoy the tunes.

Hank Williams Sr.

"Hey Good Lookin'"
Recorded in 1951, "Hey Good Lookin'" had to wait half a century to be inducted into the Grammy Hall of Fame. Like many of Hank's best songs, it's been covered by a diverse array of other artists, including Jimmy Buffet, Johnny Cash, Joe Pass, the Minutemen and Buckwheat Zydeco.

"Long Gone Lonesome Blues"

This was Hank's second number one song on the Country & Western chart, and Hank Jr.'s cover of it, recorded when he was 14, peaked at number five. This is also the song that, when played on the stereo at work, prompted my boss to observe that I "listen to some real redneck @#%$."

"Move It On Over"
Hank's first major hit, which reached #4 on the Country Singles chart. Was later covered by Ray Charles, Bill Haley (as in Bill Haley and the Comets), Hank Williams Jr. and, most famously, George Thorogood.

"I'm So Lonesome I Could Cry"
Rolling Stone ranked this #111 on their list of the 500 Greatest Songs of All Time, to which I say, "You ignorant hippies, cut your hair and get a job." (While we're at it: "Satisfaction" at #2? Seriously? Did you guys never get a copy of Exile on Main Street?) "I'm So Lonesome I Could Cry" has been covered by Bob Dylan, Elvis, Little Richard, and Terry Bradshaw. The song inspired me to formulate "Hank's Law": "the quality of a country song can, more often than not, be judged by the amount of time it takes for the singer to mention a whip-poor-will."

Hank Williams Jr.

"The Conversation" (w/ Waylon Jennings)
Two country greats sit in a dark bar, drink, smoke, and heap praise upon Hank Sr. "You know when we get right down to it still the most wanted outlaw in the land."

"All My Rowdy Friends Are Coming over Tonight"
Even if you've never heard Hank Jr.'s '84 album Major Moves, you probably know this song (the version below is from a Tupelo, MS concert last July) from Monday Night Football. Williams reworked the tune ABC Sports in the late 80s and it can still be heard on MNF on ESPN.

"That's How They Do It in Dixie"
Between the setup, the stereotyping, the aping for the camera and the appearance of the late Ronnie Van Zant's brothers, this is a country music video highlight.

"Jambalaya (On the Bayou)"
This song was made popular by Hank Sr., though the origins of the songs are a little unclear. Here, Hank Jr. performs it in concert with a four-year-old kid named Hunter Hayes. If anyone's wondering what to get me for my birthday, an accordion with a crawdad design on it will do just fine.

Hank Williams III

"Pills I Took"
This is Hank III's version of a song by a Wisconsin group called Those Poor Bastards. The original is much noisier and more aggressive, but the subject matter is right at home in a country song. (Contains a few NSFW words).

"Low Down"
This is a personal favorite from Hank III's 2006 album, Straight to Hell, which was recorded in lap steel player Andy Gibson's East Nashville home on a $400 Korg digital workstation and produced and engineered by Williams, Gibson and another bandmate.

"My Drinkin' Problem"
Live at Ziggy's in Winston-Salem, NC, in October 2006. Notable for being the Damn Band's first live appearance with a banjo player.

"Cocaine Blues"
The Johnny Cash classic, sped up and roughed up, live in Spartanburg, SC.

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!

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.
