Recommendation systems

cdixon:

It seems that users have spoken and that recommendation systems are a feature, not a product. On the web, this means that recommendations either need to be 1) embedded in a consumption experience, the way they are on Amazon or Netflix, or 2) attached to a discovery mechanism, which (usually) means SEO’d via Google a la TripAdvisor and Yelp.

I learned this the hard way at Hunch. Ultimately, it was obvious that the best use of our technology was to embed it on eBay. I’d be excited if a standalone recommendation system succeeded, but until it happens I’m skeptical.

Dang. I respect Chris’s directness.

I decided to experiment with what happens when I start liking stuff in Facebook. The result is basically that Facebook will then dump info about these things in my dashboard. 

I checked Facebook a few minutes ago and saw a scene from Dexter. I don’t normally watch TV shows as they’re aired because I prefer to watch the whole season when it’s finished. The scene in my dashboard revealed a character from the first season, effectively creating a spoiler for one of my favorite shows. This sucks. I can’t imagine Michael C Hall or Jennifer Carpenter would be so inconsiderate, but the people who want to sell the show obviously are.

I don’t want info about my favorite brands turning up in my social feeds. I want info from the people creating the brands. I follow Omar Rodriguez Lopez on Tumblr and love when one of his posts ends up in my Tumblr dashboard. I know it either came from him or someone at his label and they’re trying to share what he’s up to. Maybe he’s touring. Maybe he did an interview.

As I thought about these two different approaches, I realized I was comparing a TV show with a musician. Apples and oranges, but according to the world of social media, both are still fruit. When I get to enjoy a concert it’s because the musician is there performing right in front of me. When I watch a tv show, the actors aren’t there sharing the experience with me, they recorded the show months back and could be anywhere by the time the show airs.

It’s possible a tv show’s best bet for social interaction is to act as though the story is unfolding via their streams as the storyline is aired, but they risk ruining the experience for fans of the show that aren’t glued to their tv’s. They can’t really share a live experience and tv shows don’t tour the country, after all.

8bitfuture:

Science answers “Should I walk or run to stay dry in the rain?”
Finally science has answered the dilemma, thanks to a paper published in the European Journal of Physics. It’s a serious paper, with lots of equations and graphs going on - you can read the whole deal here, but the summary is:
If rain is falling vertically, run as quickly as possible.
If you’re going into a headwind, also run as quickly as possible.
If you have a tailwind, things get more complicated:

For motion downwind, there may be an optimal speed, which equals the component along the direction of motion of the wind velocity. This happens only if the ratio between the cross-section of the body perpendicular to the motion and the horizontal one is large enough; otherwise, the best choice is again to run at the maximum speed one can reach.

Of course you could always laugh in the face of science and, you know, use an umbrella.

Um, thanks 1000 years of western science.

Must be shared.

Neil deGrasse Tyson is asked if he’s an atheist or agnostic.

His response first discusses the fairness of the question. He then talks about what it means to be atheist or agnostic. His response feels largely conservative by attempting to say he doesn’t have an opinion, by way of not having evidence say one thing or the other is true, and then asserts that because of that he doesn’t even want a label applied to him.

Not having a label sets him free.

brycedotvc:

Look into Henry Rollins’ eyes as he recounts his story of a lucky break and a life of determined action to make the most of it. Hear beyond the words to what motivated him more than fame or money and how he describes the alternative path of life he was running from.

Hustle. Determination. Tenacity. Fear.

Entrepreneurship comes in all shapes and evades a single adjective or verb. It’s a complex cocktail of risks taken and evaded. It’s a way of life that many are drawn to for opportunity or a haven for others running from the alternative.

Henry’s story gives a glimpse into the less often discussed latter source of motivation.

This is so great. I love when he says, “I should probably shut up and learn instead of shoot my mouth off”.

if you grew up on skate videos like I did, this is a really special piece. 

I was glued to a skateboard when I was younger. I still ride from time to time, too.

The description of the frustration is so good. It’s exactly right. The falls hurt and seem unnecessary but the trick has to be achieved. It just has to. Every attempt that doesn’t succeed hurts, takes energy and means you still, for whatever reason, haven’t landed this damn trick yet. ARGH WTF!!.

Building software projects can be similar. I take the expression of my ideas very seriously. I love when something works very smoothly. It’s like landing a perfect 360 flip, but instead lots of people can enjoy your work. Functionality is the name of the game with software and it can easily be shared. Skating feels closer to an artistic display of physical control instead of something that can be shared easily. Don’t misunderstand me, skating can definitely be shared. We skate in groups and share videos of the pros, but it’s difficult to enhance my life with these things unless I too am a skateboarder.

I really enjoy the discussion of Lance Mountain and his contributions to getting skateboarding in the mainstream. They describe him as something of a Carl Sagan character. He’s not necessarily doing the hardest tricks, but he’s having a good time and showing how fun skateboarding can be. Sagan’s Cosmos series does exactly this. It just makes you think and tries to encourage an interest in science.

I spent so much time on a skateboard. I loved it. I could do switch 360 flips, inward heelflips and probably landed most tricks at least once. There was always more to do. Weirder stuff to try. More stairs to jump down. It was also my reason to visit NYC when I was a kid. I’d take the train with a few friends, whom I later played in bands with, and we’d head down to the Brooklyn Banks for the day. Sometimes we’d see a band before going home.

I love the way skaters always talk about their sport like it’s actually art. They describe skaters pushing the sport forward or landing very cleanly or focusing on really technical tricks or mastering all their tricks switch stance. The device itself is just a plank of wood with wheels, so there’s a lot of interesting things one can figure out how to do.

The discussion of the video parts captures that too. They discuss the music used for the section, the series of tricks displayed, how to capture the consistency of a skater’s abilities.

Richard Feynman - The Pleasure Of Finding Things Out

I consider Feynman to be as much of an artist as he is a scientist. Only people that view their trade as beautiful, elegant, flawed and wonderful can talk about it the way he does. It’s not just what he’s learning, but why it exists as it does. It needs to fit into what he knows of some bigger picture. He likes to pull ideas apart and put them back together in other ways to see if they’re still consistent and he did so relentlessly.

He delights in his understanding of things in the world and tells stories about being a little naughty or learning something new or exploring an idea for the joy of seeing where it takes him. He talks as though the truth doesn’t care about what people think, so he tries to adapt how he thinks to what the truth, as shown by experiment, says instead.

By embracing a scientific curiosity, he is also comfortable with what he doesn’t know. If something can be discovered, he’ll work to do it, but there’s no harm in not knowing something. It’s actually the norm, until you intentionally try to learn something.

This particular section of the video captures his view of knowledge, and the journey of acquiring knowledge, eloquently.

If you are interested in the ultimate character of the physical world, or the complete world, and at the present time our only way to understand that is through a mathematical type of reasoning, then I don’t think a person can fully appreciate, or in fact can appreciate much of, these particular aspects of the world, the great depth of character of the universality of the laws, the relationships of things, without an understanding of mathematics. I don’t know any other way to do it, we don’t know any other way to describe it accurately … or to see the interrelationships without it. So I don’t think a person who hasn’t developed some mathematical sense is capable of fully appreciating this aspect of the world – don’t misunderstand me, there are many, many aspects of the world that mathematics is unnecessary for, such as love, which are very delightful and wonderful to appreciate and to feel awed and mysterious about; and I don’t mean to say that the only thing in the world is physics, but you were talking about physics and if that’s what you’re talking about, then to not know mathematics is a severe limitation in understanding the world.
