In just about any field, somebody can initially fake you out by saying all the right things. But in reality, there is a huge difference between real professionals and people who are just pretending.

The problem comes when the pretenders need to respond to a challenge in real time. That’s when you can really see the difference between simply quoting things that sound good, and actually knowing one’s stuff.

There was a great example of this during the second presidential debate of this election cycle, in the following exchange between Donald Trump and Hillary Clinton:

TRUMP: First of all, she was there as secretary of state with the so-called line in the sand, which…

CLINTON: No, I wasn’t. I was gone. I hate to interrupt you, but at some point…

TRUMP: OK. But you were in contact — excuse me. You were…

CLINTON: At some point, we need to do some fact-checking here.

TRUMP: You were in total contact with the White House, and perhaps, sadly, Obama probably still listened to you.

In essence, what Trump had said was correct. Clinton had indeed been the Secretary of State when the “line in the sand” policy was created. But Trump didn’t know that, because he was just reciting sound bites that somebody had fed him.

Clinton — who, unlike Trump, is actually a politician — knew perfectly well that Trump was just reciting words that he himself didn’t fully understand. So she pointed out, correctly, that she was no longer Secretary of State when the Obama administration eventually crossed that “line in the sand”. She knew that Trump would not realize she had switched topics.

Sure enough, Trump took the bait. He was reduced to saying, rather lamely, “You were in total contact with the White House”, and “Obama probably still listened to you,” essentially confirming the impression that Clinton was correct, and that he himself had been wrong.

It was a moment that laid bare the vast difference between an actual politician and an actor who is merely reciting lines.

Messages running forwards and backwards, like endlessly unfolding palindromes, containing phrases with refulgent ideas exalted by revealed mysteries, express truths spiralling outward exquisitely, as exquisitely outward spiralling truths express mysteries revealed by exalted ideas refulgent with phrases containing palindromes unfolding endlessly, like backwards and forwards running messages.

Should time somehow flip,
Would I then still post a blog?
Would I pre a blog?

Blog a pre I would.
Blog a post still then I would!
Flip somehow, time should.

Today I went to a football game at Yankee Stadium. Or, as we call it in the U.S., soccer.

It was really fun. I had not been to a live soccer game in years, since my time in Brazil. And in the end the home team won, which always makes (nearly) everybody happy.

There were lots of kids there — a lot more kids than I’ve ever seen at a baseball game at Yankee Stadium. It’s great that young kids in New York are interested in soccer. I’m not sure what it means. Perhaps it represents a demographic shift, or maybe young kids just find soccer more fun and exciting than baseball or American football. Whatever the reason, I think it’s good.

Speaking of American football, we had a bit of a chat about why that game is called football. I had always wondered about that. After all, you don’t really use your feet to play it. And come to think of it, you don’t really use a ball. More of an oblong shaped thing.

Somebody said that it’s called “football” because the “ball” is a foot long. That sounded intriguing, so I looked it up when I got home. And it turns out that’s not true. The actual reason, as well as the reason we call the other game “soccer”, involves a complicated and somewhat politically charged history.

But this has been an exhausting election season, and I find myself tired of political football. So maybe I’ll go into that history another time. For now, I’m just going to kick the ball down the field.

I enjoyed this evening’s Saturday Night sketch inspired by the third and final presidential debate. Yet I found it dissatisfying for the oddest reason.

The reality had become so bizarre that there was pretty much nothing SNL could do to effectively parody it. Not that they didn’t try.

But what happens when an actual candidate for president says things of his opponent like “Such a nasty woman”, and won’t even agree to accept the outcome of the election? That’s an entirely new level of pitch black political gallows humor.

And that’s the moment when the reality crosses over and exceeds the parody. You just can’t top stuff like that.

We generally don’t pick out all of the furniture for our new home or apartment before we get there. After all, we might get it wrong.

Sure, there are software tools out there that let you do this sort of thing. You can place computer graphic versions of your bed, your sofa or your nightstand around the room, try different lighting arrangements, and see the result from various angles at different times of day.

Of course that is different from really being in the room. A picture of a room is not the same as being in the room itself.

Yet that might change. At some point you will take for granted the ability to slip on your lightweight hologlasses, which will let you have the experience of being in any room you like. Unlike today’s high end room-scale VR platforms, you will be able to wander around freely, unencumbered by wires or cables.

You might very well find yourself picking out the furniture you like, secure in the knowledge that there will be no unpleasant visual surprises when you walk into the room itself.

In fact, even after you are living somewhere, you might, on occasion, choose to pop on your hologlasses and virtually rearrange the furniture. The next time you come back into that room, unobtrusive robots will have already shifted around the physical objects in the room to match your new preference.

You might even store some favorite room arrangements, to fit your different moods and preferences. One day things are set up for studying, the next day for that dinner party you’ve been meaning to throw.

I can’t wait! 🙂

Today I was with a group of people I’d never met before. One thing we all had in common was a love of science. As we talked, it gradually came out that we all had a particular cultural touchstone in common: Our love for A Wrinkle in Time.

In fact, we had all read it when we were little, and had been drawn by its mysteries into wanting to learn about math, science, physics, and all the various grown-up topics that Madeleine L’Engel ingeniously referenced in what was ostensibly a children’s story. At a moment when people are becoming very interested in all forms of virtual reality, her book seems especially relevant.

To me there was always something iconic about the scene where Mrs. Who and Mrs. Whatsit demonstrate how the “wrinkle in time” of the title actually works — so clear and child-friendly, yet so deep in its implications. Looking now from the perspective of adulthood, I understand now that the story contains little actual science or math. It’s pretty much all suggested by metaphor.

But as a young boy, I became completely lost in the mystery and wonder of the Universe, as seen through the eyes of Meg and Charles Wallace Murry. Reading this book made me want to learn about science and math, so I could go on my own journey of mystery and wonder.

Which I think is a pretty good effect for a book to have on a child.

I am so relieved. Somehow I had been worried that during this last presidential debate, some body snatcher might temporarily replace the eighth grade bully on the Republican side of the stage by a convincing semblance of an adult candidate.

But that did not happen. On the right side of our TV screen we saw a calm, articulate, highly competent, well informed grown-up addressing the issues with wit and depth, expressing her views in clear detail and with consistent intellectual force.

On the left side of our TV screen we saw a petulant eighth grade bully. There is something unnerving about seeing a seventy year old would-be statesman whose game is pretty much on the level of a fourteen year boy accustomed to beating up his classmates for their lunch money.

I felt bad for the millions of Trump supporters who had to watch that performance. I felt even worse for them when their standard bearer engaged in something even more disturbing: Suggesting that he might not accept defeat, and thereby attacking the electoral process itself.

As Hillary Clinton said tonight, in a different context: “I mean, who does that?”

I’ve been working on a math / programming problem the last few days. It has required me to work out lots of different problems, and implement various image-analysis algorithms.

I’ve needed to figure out how to compute curves from discrete points, do sub-pixel sampling, adapt a marching-squares algorithm, construct optimal histograms and then analyze them, create graphical visualizations of potential sources of deviation from the mean, and employ various other complementary techniques. Since errors are cumulative, every step has needed to be very precise, with very little wiggle room.

You can sometimes learn a lot about yourself, just by how you respond emotionally to such challenges. What I’ve learned is that I am having the time of my life. In fact, it has all been pure joy.

Which is a good thing to know.

Around twenty years ago, a new phrase entered the computer-tech culture: “Graphics Processing Unit”, or GPU. The general currency of this term started when the high end computer graphics of th ’90s (Silicon Graphics in particular) had officially become a dinosaur, and so was duly shoved aside by the warm furry mammals of low end commodity hardware, such as nVidia, ATI, and their competitors.

We now take hardware-accelerated 3D graphics for granted in all our information devices, including our phones. It would be unheard of, in this day and age, for a SmartPhone to not have a GPU.

As we make the transition to wearables, something similar is about to happen with computer vision. A dedicated co-processor — a Vision Processing Unit, if you will, or VPU — entirely devoted to figuring out what you are seeing when you look out into the world, will soon be part of every consumer-level information device.

As soon as we put on our cyber-glasses, we will able to tell where we are and who we are looking at. Inferenced based on real-time object recognition of doors, bottles, furniture, cars, or whatever, will be taken for granted by a young generation that will never have known anything else.

Sixteen years ago, the new Millenium brought with it the age of the GPU: an era of affordable consumer-level high performance 3D computer graphics that is now in every phone and laptop computer. We are now about to enter the age of the VPU. Whatever we look at, our wearable device will recognize it, and will help us figure out what to do about it.

In not so many years, a generation will come of age that will think of this not as something magical, but simply as reality.
