Remembering David Foster Wallace

Original image

Not that I knew him particularly well or really at all, save through his writing, but I did meet Wallace, one of America's youngest literary giants, in 1998 or '99, when he did a reading at Kenyon College, where I was an undergrad. A group of fellow English nerds and myself had the pleasure of hanging out with him a bit afterwards, and I remember being impressed by how humble, and unbelievably, almost cripplingly intelligent he was; the kind of person who has so many thoughts racing through their head at once that they can barely finish a sentence because better sentences occur to them while they're speaking the first one.

For those of you who aren't familiar with his work and don't know why we're remembering him, DFW was most famous for his staggering second novel, the 1,079-page Infinite Jest, published in 1996 when he was just 33. It infamously featured more than 90 pages of endnotes not to mention footnotes throughout; part of his unique style was to constantly interrupt the narrative flow with new ideas, sort of like he did in everyday conversation. For the past six years, Wallace has taught creative writing at Pomona College outside of LA; a few days ago he was found dead in his home, apparently by suicide. He will be missed.

Because it's so difficult to encapsulate someone so prolific, all I can do is choose a few bits of Wallace-ness that seem to get at who he is as a storyteller. In 2005 he gave the commencement address at Kenyon College, and the speech has since become legendary. It's an unconventional, profound and frequently hilarious piece of writing -- and it's so good, I include it here in its entirety. Read it all if you can: it's the briefest distillation of Wallace's genius you're likely to find.

Greetings and congratulations to Kenyon's graduating class of 2005. There are these two young fish swimming along and they happen to meet an older fish swimming the other way, who nods at them and says "Morning, boys. How's the water?" And the two young fish swim on for a bit, and then eventually one of them looks over at the other and goes "What the hell is water?"

This is a standard requirement of US commencement speeches, the deployment of didactic little parable-ish stories. The story ["thing"] turns out to be one of the better, less bullshitty conventions of the genre, but if you're worried that I plan to present myself here as the wise, older fish explaining what water is to you younger fish, please don't be. I am not the wise old fish. The point of the fish story is merely that the most obvious, important realities are often the ones that are hardest to see and talk about. Stated as an English sentence, of course, this is just a banal platitude, but the fact is that in the day to day trenches of adult existence, banal platitudes can have a life or death importance, or so I wish to suggest to you on this dry and lovely morning.

Of course the main requirement of speeches like this is that I'm supposed to talk about your liberal arts education's meaning, to try to explain why the degree you are about to receive has actual human value instead of just a material payoff. So let's talk about the single most pervasive cliché in the commencement speech genre, which is that a liberal arts education is not so much about filling you up with knowledge as it is about quote teaching you how to think. If you're like me as a student, you've never liked hearing this, and you tend to feel a bit insulted by the claim that you needed anybody to teach you how to think, since the fact that you even got admitted to a college this good seems like proof that you already know how to think. But I'm going to posit to you that the liberal arts cliché turns out not to be insulting at all, because the really significant education in thinking that we're supposed to get in a place like this isn't really about the capacity to think, but rather about the choice of what to think about.

...

Twenty years after my own graduation, I have come gradually to understand that the liberal arts cliché about teaching you how to think is actually shorthand for a much deeper, more serious idea: learning how to think really means learning how to exercise some control over how and what you think. It means being conscious and aware enough to choose what you pay attention to and to choose how you construct meaning from experience. Because if you cannot exercise this kind of choice in adult life, you will be totally hosed. Think of the old cliché about quote the mind being an excellent servant but a terrible master.

This, like many clichés, so lame and unexciting on the surface, actually expresses a great and terrible truth. It is not the least bit coincidental that adults who commit suicide with firearms almost always shoot themselves in: the head. They shoot the terrible master. And the truth is that most of these suicides are actually dead long before they pull the trigger.

And I submit that this is what the real, no bullshit value of your liberal arts education is supposed to be about: how to keep from going through your comfortable, prosperous, respectable adult life dead, unconscious, a slave to your head and to your natural default setting of being uniquely, completely, imperially alone day in and day out. That may sound like hyperbole, or abstract nonsense. Let's get concrete. The plain fact is that you graduating seniors do not yet have any clue what "day in day out" really means. There happen to be whole, large parts of adult American life that nobody talks about in commencement speeches. One such part involves boredom, routine, and petty frustration. The parents and older folks here will know all too well what I'm talking about.

By way of example, let's say it's an average adult day, and you get up in the morning, go to your challenging, white-collar, college-graduate job, and you work hard for eight or ten hours, and at the end of the day you're tired and somewhat stressed and all you want is to go home and have a good supper and maybe unwind for an hour, and then hit the sack early because, of course, you have to get up the next day and do it all again. But then you remember there's no food at home. You haven't had time to shop this week because of your challenging job, and so now after work you have to get in your car and drive to the supermarket. It's the end of the work day and the traffic is apt to be: very bad. So getting to the store takes way longer than it should, and when you finally get there, the supermarket is very crowded, because of course it's the time of day when all the other people with jobs also try to squeeze in some grocery shopping. And the store is hideously lit and infused with soul-killing muzak or corporate pop and it's pretty much the last place you want to be but you can't just get in and quickly out; you have to wander all over the huge, over-lit store's confusing aisles to find the stuff you want and you have to maneuver your junky cart through all these other tired, hurried people with carts (et cetera, et cetera, cutting stuff out because this is a long ceremony) and eventually you get all your supper supplies, except now it turns out there aren't enough check-out lanes open even though it's the end-of-the-day rush. So the checkout line is incredibly long, which is stupid and infuriating. But you can't take your frustration out on the frantic lady working the register, who is overworked at a job whose daily tedium and meaninglessness surpasses the imagination of any of us here at a prestigious college.

But anyway, you finally get to the checkout line's front, and you pay for your food, and you get told to "Have a nice day" in a voice that is the absolute voice of death. Then you have to take your creepy, flimsy, plastic bags of groceries in your cart with the one crazy wheel that pulls maddeningly to the left, all the way out through the crowded, bumpy, littery parking lot, and then you have to drive all the way home through slow, heavy, SUV-intensive, rush-hour traffic, et cetera et cetera.

Everyone here has done this, of course. But it hasn't yet been part of you graduates' actual life routine, day after week after month after year.

But it will be. And many more dreary, annoying, seemingly meaningless routines besides. But that is not the point. The point is that petty, frustrating crap like this is exactly where the work of choosing is gonna come in. Because the traffic jams and crowded aisles and long checkout lines give me time to think, and if I don't make a conscious decision about how to think and what to pay attention to, I'm gonna be pissed and miserable every time I have to shop. Because my natural default setting is the certainty that situations like this are really all about me. About MY hungriness and MY fatigue and MY desire to just get home, and it's going to seem for all the world like everybody else is just in my way. And who are all these people in my way? And look at how repulsive most of them are, and how stupid and cow-like and dead-eyed and nonhuman they seem in the checkout line, or at how annoying and rude it is that people are talking loudly on cell phones in the middle of the line. And look at how deeply and personally unfair this is.

Or, of course, if I'm in a more socially conscious liberal arts form of my default setting, I can spend time in the end-of-the-day traffic being disgusted about all the huge, stupid, lane-blocking SUV's and Hummers and V-12 pickup trucks, burning their wasteful, selfish, forty-gallon tanks of gas, and I can dwell on the fact that the patriotic or religious bumper-stickers always seem to be on the biggest, most disgustingly selfish vehicles, driven by the ugliest [responding here to loud applause] (this is an example of how NOT to think, though) most disgustingly selfish vehicles, driven by the ugliest, most inconsiderate and aggressive drivers. And I can think about how our children's children will despise us for wasting all the future's fuel, and probably screwing up the climate, and how spoiled and stupid and selfish and disgusting we all are, and how modern consumer society just sucks, and so forth and so on.

You get the idea.

If I choose to think this way in a store and on the freeway, fine. Lots of us do. Except thinking this way tends to be so easy and automatic that it doesn't have to be a choice. It is my natural default setting. It's the automatic way that I experience the boring, frustrating, crowded parts of adult life when I'm operating on the automatic, unconscious belief that I am the center of the world, and that my immediate needs and feelings are what should determine the world's priorities.

The thing is that, of course, there are totally different ways to think about these kinds of situations. In this traffic, all these vehicles stopped and idling in my way, it's not impossible that some of these people in SUV's have been in horrible auto accidents in the past, and now find driving so terrifying that their therapist has all but ordered them to get a huge, heavy SUV so they can feel safe enough to drive. Or that the Hummer that just cut me off is maybe being driven by a father whose little child is hurt or sick in the seat next to him, and he's trying to get this kid to the hospital, and he's in a bigger, more legitimate hurry than I am: it is actually I who am in HIS way.

Or I can choose to force myself to consider the likelihood that everyone else in the supermarket's checkout line is just as bored and frustrated as I am, and that some of these people probably have harder, more tedious and painful lives than I do.

Again, please don't think that I'm giving you moral advice, or that I'm saying you are supposed to think this way, or that anyone expects you to just automatically do it. Because it's hard. It takes will and effort, and if you are like me, some days you won't be able to do it, or you just flat out won't want to.

But most days, if you're aware enough to give yourself a choice, you can choose to look differently at this fat, dead-eyed, over-made-up lady who just screamed at her kid in the checkout line. Maybe she's not usually like this. Maybe she's been up three straight nights holding the hand of a husband who is dying of bone cancer. Or maybe this very lady is the low-wage clerk at the motor vehicle department, who just yesterday helped your spouse resolve a horrific, infuriating, red-tape problem through some small act of bureaucratic kindness. Of course, none of this is likely, but it's also not impossible. It just depends what you what to consider. If you're automatically sure that you know what reality is, and you are operating on your default setting, then you, like me, probably won't consider possibilities that aren't annoying and miserable. But if you really learn how to pay attention, then you will know there are other options. It will actually be within your power to experience a crowded, hot, slow, consumer-hell type situation as not only meaningful, but sacred, on fire with the same force that made the stars: love, fellowship, the mystical oneness of all things deep down.

Not that that mystical stuff is necessarily true. The only thing that's capital-T True is that you get to decide how you're gonna try to see it.

It is about the real value of a real education, which has almost nothing to do with knowledge, and everything to do with simple awareness; awareness of what is so real and essential, so hidden in plain sight all around us, all the time, that we have to keep reminding ourselves over and over:

"This is water."

"This is water."

It is unimaginably hard to do this, to stay conscious and alive in the adult world day in and day out. Which means yet another grand cliché turns out to be true: your education really IS the job of a lifetime. And it commences: now.

I wish you way more than luck.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
Original image
iStock // Ekaterina Minaeva

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!

Why Your iPhone Doesn't Always Show You the 'Decline Call' Button
Original image

When you get an incoming call to your iPhone, the options that light up your screen aren't always the same. Sometimes you have the option to decline a call, and sometimes you only see a slider that allows you to answer, without an option to send the caller straight to voicemail. Why the difference?

A while back, Business Insider tracked down the answer to this conundrum of modern communication, and the answer turns out to be fairly simple.

If you get a call while your phone is locked, you’ll see the "slide to answer" button. In order to decline the call, you have to double-tap the power button on the top of the phone.

If your phone is unlocked, however, the screen that appears during an incoming call is different. You’ll see the two buttons, "accept" or "decline."

Either way, you get the options to set a reminder to call that person back or to immediately send them a text message. ("Dad, stop calling me at work, it’s 9 a.m.!")
