How Scotch Nerds April Fool One Another

Original image

He gets us every year. That's Andy, the founder and fearless leader of the Los Angeles Scotch Club, who last year punked dozens of members with this last-minute meeting announcement:

Scotch Clubbers,

Years of schmoozing may have finally paid off. Master Distiller John Campbell of Laphroaig, who a few of you may remember from his free tasting in Hollywood last year (he brought the 18), called me last night. We talked a long time last year and he was impressed with the club. Anyway, he was in town to do a private birthday tasting today for some rich guy (I assume)… who ended up in the hospital last night. Party cancelled. So, he has 7 bottles of LAPHROAIG 30, a prepaid location on Sunset Blvd, and doesn’t want to waste it tonight. It is free. They may have hors ‘d oeuvres too (not sure). Please email me for the location since he needs to know how many are coming (I think there is a limit too). Remember, it’s tonight, 7pm, April 1.

Hope to see you tonight!

We were understandably excited, as Laphroaig 30 is not only delicious, but goes for like $600/bottle, way above the drinking budget of most members. Alas, it was all a filthy lie. So you would think that this year we'd be onto Andy and his tricks, when this meeting announcement hit our inboxes on the first of April:

So the LASC has a chance for some more free whisky. It’s kind of last-minutey (sorry), but it’s virtually free and it’s single malt. We just had an awesome Japanese Whisky night, but I bet you didn’t know that there’s a new cottage industry for scotch-like whisky in the highlands of Mexico. Alex Mentiroso is the rep for three very small distilleries about 90 miles southeast of Mexico City. He’ll be pouring the following single malts:

Tonto Deabril
Valle del Ivet

Space is limited to 20 people, so reserve soon. I’ve set up Paypal for a token 50 cent fee just so that I can use it for reservations. We’ll be doing it at El Cholo. See reservation page for address and details.

As further proof, he attached an image of the first whisky on the list, Tonto Deabril. We were all looking at the bottle -- that nice wax-dip sealing the cork, the rich golden color of the spirit itself -- and thinking, sure, maybe there's a Mexican Scotch whisky industry. After all, we just did a tasting of Japanese whisky and another of Indian whisky -- the Japanese was better, but both were pretty good -- so it wasn't out of the realm of possibility. Of course, it was just a joke. The bottle to the left is illegal Mezcal with the name photoshopped -- Tonto Deabril means fool of April. As for the other Mexican scotch-style whiskies -- there are none -- "Bajolamesa" means "under the table" and, in a humiliating follow-up email sent April 2, Andy pointed out that "Valle del Ivet = Valle de Livet = Livet Valley = Glen Livet." And then we all felt very dumb. Which I guess is the point of April Fool's Day, even for Scotch nerds.

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!

Here's How to Change Your Name on Facebook
Original image

Whether you want to change your legal name, adopt a new nickname, or simply reinvent your online persona, it's helpful to know the process of resetting your name on Facebook. The social media site isn't a fan of fake accounts, and as a result changing your name is a little more complicated than updating your profile picture or relationship status. Luckily, Daily Dot laid out the steps.

Start by going to the blue bar at the top of the page in desktop view and clicking the down arrow to the far right. From here, go to Settings. This should take you to the General Account Settings page. Find your name as it appears on your profile and click the Edit link to the right of it. Now, you can input your preferred first and last name, and if you’d like, your middle name.

The steps are similar in Facebook mobile. To find Settings, tap the More option in the bottom right corner. Go to Account Settings, then General, then hit your name to change it.

Whatever you type should adhere to Facebook's guidelines, which prohibit symbols, numbers, unusual capitalization, and honorifics like Mr., Ms., and Dr. Before landing on a name, make sure you’re ready to commit to it: Facebook won’t let you update it again for 60 days. If you aren’t happy with these restrictions, adding a secondary name or a name pronunciation might better suit your needs. You can do this by going to the Details About You heading under the About page of your profile.
