At the Libraries: Librarian Stereotypes

Original image

Each week Miss Kathleen provides links to a variety of stories about libraries, authors, and books. If there's something fun going on in your local library, leave us a comment!

Stephen's Lighthouse pointed me to this great infographic about librarian stereotypes. See, I cut my hair short, so I couldn't even wear a bun if I wanted to! (Click to enlarge.)

*
Can you handle more awesome bookshelves? They just don't stop coming -- check these amazing ones out.
*
And now for a few amazing libraries. The first one, in Germany is just about the coolest design I've ever seen. I kind of want to live there.
*
You used to have to wait a while for a book to come out in paperback (and thus be affordable), but now that process is being accelerated, thanks to e-books.
*
Wow, that NYPL, what will they do next? They keep bringing on the good news. This week, they are granting amnesty to kids who owe overdue fees.
*
Forgiving fines isn't all we do! Participate in this week's Library Day in the Life Project and share the ups and downs of your week. With all these heat waves bringing people through our doors, I'm sure you guys have had plenty of excitement.
*
Speaking of heat waves, New York City has designated cooling centers for citizens to seek relief, and one of them is a library. Too bad the folks working there didn't know that. Read The Awl's funny piece about seeking cool air on a hot day.
*
Here's a different kind of library (and not a free one!): a pop-up art installation that will recommend books after talking to you.
*
But if you can't make it to Tokyo in time (it closes July 31, so you'd have to move fast), try this website. Enter the name of an author you like, and it gives you suggestions for other writers to try. Sounds a lot like what I do all day, but, you know, less personalized.
*
Ever look at an old children's book and think ugh, what a disastrously ugly cover? Trust me, this happens all the time when I reach for a classic on my library's shelves. Travis over at 100 Scope Notes is taking on the Newbery winners from way back and re-imagining the covers, with some great results. Take a gander at his work so far.
*
It seems like a lot of people want to tweak publisher's official cover art -- and who could blame them? Here's a blog devoted to highlighting new cover art for children's books, with some really beautiful stuff.
* * *
That's all for this week, friends. Thanks for reading, and email me if you have any exciting library news to report! Also, next week it's time for August's Blog of the Month. If you have some ideas, holla!

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.
