How to Roll Like Ben Franklin

Original image

Benjamin Franklin was kind of a big deal. He penned Poor Richard's Almanack, invented the lightning rod, bifocals, the rockin' glass harmonica, and a bunch of other great stuff. He was a politician, statesman, and diplomat (and made a killer appearance, in a bathtub in France, in HBO's recent John Adams miniseries). He's the eponymous Benjy featured on the U.S. One Hundred Dollar Bill. So how did Ben get so great? By following a code of "thirteen virtues," a set of guidelines for living that he developed in 1726, at the ripe young age of 20. Here they are:

1. TEMPERANCE. Eat not to dullness; drink not to elevation.

2. SILENCE. Speak not but what may benefit others or yourself; avoid trifling conversation.

3. ORDER. Let all your things have their places; let each part of your business have its time.

4. RESOLUTION. Resolve to perform what you ought; perform without fail what you resolve.

5. FRUGALITY. Make no expense but to do good to others or yourself; i.e., waste nothing.

6. INDUSTRY. Lose no time; be always employ'd in something useful; cut off all unnecessary actions.

7. SINCERITY. Use no hurtful deceit; think innocently and justly, and, if you speak, speak accordingly.

8. JUSTICE. Wrong none by doing injuries, or omitting the benefits that are your duty.

9. MODERATION. Avoid extreams; forbear resenting injuries so much as you think they deserve.

10. CLEANLINESS. Tolerate no uncleanliness in body, cloaths, or habitation.

11.TRANQUILLITY. Be not disturbed at trifles, or at accidents common or unavoidable.

12. CHASTITY. Rarely use venery but for health or offspring, never to dulness, weakness, or the injury of your own or another's peace or reputation.

13. HUMILITY. Imitate Jesus and Socrates.

Wikipedia provides this helpful footnote (emphasis added):

Franklin didn't try to work on them all at once. Instead, he would work on one and only one each week "leaving all others to their ordinary chance". While Franklin didn't live completely by his virtues and by his own admission, he fell short of them many times, he believed the attempt made him a better man contributing greatly to his success and happiness, which is why in his autobiography, he devoted more pages to this plan than to any other single point; in his autobiography Franklin wrote, "I hope, therefore, that some of my descendants may follow the example and reap the benefit."

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:

Opening Ceremony

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.
