Facebook + Location

As Facebook has grown internationally into a worldwide network, we’ve come to realize that organizing our users into geographic networks isn’t as useful as knowing where a user is currently located.

Does this mean I will finally be able to ask Facebook, “Hey, I’m going to San Francisco, which of my friends are there?”.

One Velociraptor Per Child

This is another micro-essay from my Harvard Business School app. It is about One Velociraptor Per Child.

Last summer, one of my friends worked for the One Laptop Per Child organization, which strives to enable education in third world countries. She had an idea for a funny parody of OLPC, “One Velociraptor Per Child.” Velociraptors are a popular meme in many web comics, so we thought many people would find the joke as funny as we did. We put together a website for our fictional Darwinian philanthropy, documenting the breakthroughs in paleontology that enabled our bold vision to put a velociraptor in every school. Visitors could fill out a form to express interest OVPC apparel.

With a flood of interest behind us, we invested in 200 t-shirts sporting our logo, then e-mailed our visitors and told them we were taking orders. It turns out there are a lot of steps to selling t-shirts online, but my roommate was nice enough to let me turn my dorm room into a shipping center while we figured them out. We took a financial risk on our funny idea, but we ended up selling out, and we now hear t-shirt spottings from friends in other cities.

Unicycling

This is part of a series where I post stuff I wrote for my HBS 2+2 app, but think is kind of cool.

Learning to unicycle is about learning to be comfortable while constantly on the brink of failing. Olin has a unicycling club, and after two years of watching my friends zip around on the one wheeled contraptions, I decided that I wanted to learn. It took me a few days, but I learned to go a few yards before falling off.

From that point out, unicycling becomes a mental battle. As soon as you think, “I am about to fall,” you fall. As soon as you think you’re done, you are. You have to learn to not give up, and decide, “I am not going to fall.” There is nothing fundamentally different about unicycling a mile than twenty feet, it’s just a matter of confidence.

As I practiced unicycling, I could go farther and farther at once. The difference was partially better balance, but partially more tenacity. When I lost my balance, I didn’t give up and fall to my feet, I swiveled my hips and fought to correct my center of gravity. Every extra inch I went came as much as a result of comfort with instability as better balance. If you’re afraid of failing, that’s all you’ll ever do.

In what ways are you like a volcano?

I dug this essay up while working on my HBS essays. I submitted it with my Common App, which dangerously presented an essay topic of “Answer a question of your choosing”.

“In what ways are you like a volcano?”

To the average person walking down the street, I might not look much like a volcano, but really, there is a lot that the geological landmark and I have in common.

For one thing, volcanoes can be active and spewing out lava, or dormant and slowly building up pressure until releasing it in one great eruption. Sometimes I find myself in this dormant stage, carefully watching and waiting as I slowly build up ideas for different things I could do. Then, once the possibilities in my head reach critical mass, they burst out into reality. Some are creative projects: photography or a t-shirt design. Others are more pragmatic: a new approach for a project on the robotics team or planning a fundraising event for my youth group. Either way, I like to gather information and plan before I go into action.

When a volcano erupts, it changes the environment around it. I think that I leave changes too, but in a more positive way. I tutor students in algebra and photography, using my knowledge to show them what they need to advance further. Some of my ideas have hopefully changed people’s perspective on social issues, too. Free Shirt Week was an idea of mine where classmates could stop worrying about looking cool and just wear the shirts they got for participating in some event. Many people participated and it brought a bit of flavor to school.

There is nothing that people can do to stop volcanoes, and sometimes I can be just as stubborn. Last year, on the robotics team, I worked to develop a camera system to automatically find and interact with objects based on color. People told me I would not be able to do it, but I spent hours and hours working closer and closer to my goal. I never actually reached that goal, but I learned a lot on the way there. If I had just given up, all that experience would have been lost.

When Mt. Vesuvius buried Pompeii in ash, it preserved artifacts and villas for centuries. Similarly, I believe that preserving our world for the future is very important. I enjoy photography and take lots of pictures. I hope that my photographs are preserved long enough that my grandchildren, or their grandchildren, can look at them and marvel at the world the way it ‘used to be.’ Perhaps the pictures that I now think of as artistic will be scoffed at in the future, or maybe I’ll be the next Michelangelo.

Volcanoes may seem like complex natural forces, but they can be deconstructed. I believe you can get a better idea about anything by looking at all the pieces that make it up and understanding the interrelatedness of each part. Similarly, I am a combination of many skills, interests, and experiences which when combined form the mosaic that is me.
