Parkour Visions Summit and Talk

On August 13-15th, my friends Rafe Kelley and Tyson Cecka are hosting a parkour summit at their Seattle gym Parkour Visions. For those of you not familiar with the sport, here's a description from the Parkour Visions site:

"The essence of Parkour can be stated simply: it is the art of overcoming obstacles as swiftly and efficiently as possible using only your body. The fundamentals include running, jumping, and climbing, and we build on these fundamentals to improve our ability to pass over, under, around and through obstacles with more complex movements. Parkour is a system of fitness training that improves strength, speed, agility, co-ordination, stamina, endurance, and precision. It offers a full-body workout at any level of experience, and improves your ability to move, to harness your confidence, to change how you see the world. Parkour practitioners are called traceurs."

The summit will include seminars on strength training, injury prevention and rehab, and nutrition, as well as parkour jams, a roundtable and a dinner. I'll be giving a talk titled "Natural Eating for Sustainable Athletic Performance" on Saturday, August 14 from noon to 1:00 pm.

Registration is $40 for the whole summit. You can read a description of it here, and find a link to the registration system at the bottom of this page.

The NYT has a fantastic article in this weekend's magazine on something I have been stamping my feet about for years. It is about how the permanence of our digital lives (a lack of ephemerality) is significantly affecting our physical day-to-day lives, often in adverse ways.  (I unfortunately don't have the time to summarize the article - please go read it, it's very well written.)

Our world has not only become a panopticon, but it is a permanent, indexed, fully searchable one. This is not merely your employer seeing a photo of you being goofy at a party, this is a permanent record of your daily existence of which you increasingly have absolutely no control over.

The right to anonymity and ephemerality of action is something we take for granted when acting in the physical world. The problem is that the digital world does not in any way reflect these assumptions. Not only is everything you do online often fully archived and linkable to you, but with the advent of social media everything other people post about you is too.

There are a ton of papers in the literature about how online activities we believe to be anonymous are not at all. Seemingly innocuous and anonymous net activity can reveal one's search queries, social security number, phone number, sexual orientation, political views, travel plans, oh, and, one's real identity when they thought they were anonymous. I think I meet a new researcher mining Twitter for gold just about every other day. The fact is, computer scientists are clever folks, and coming up with these kinds of algorithms is quite easy.  And they're the good guys/gals.

Being a private person, I find these papers terrifying. But when I talk to many people about it, they say, "I don't care. I have nothing to hide." This is a selfish and, frankly, privileged attitude to have. For people living in countries with authoritarian governments, anonymity is often the only path to freedom. Imagine the Underground Railroad or hidden Jews during the Holocaust being successful with 24/7 video surveillance, with automatic face tagging being posted to live feeds on Facebook. Or more recently, imagine someone using these techniques to out Iranian green party members. They'd be killed. And I don't think the counter-argument holds; I doubt such a permanent panopticon will suddenly engender good behavior.

One of the best things about our freedom as human beings is that other people quickly forget our stupid, embarrassing moments. People don't always know who we are everywhere we go. We can take many risks freely. But, increasingly, neither our technology nor our legislation is supporting us in this. And that, in my opinion, is very dangerous indeed.

Disconnected connectedness

NPR had a nice interview yesterday with the author of Hamlet's BlackBerry, William Powers. In the interview, Powers talks about how several information upgrades in recent history (Roman cities and papyrus, the printing press, and now the internet), and how, always, society struggles to cope.

Academics are of course no exception to feeling overloaded. I am presently at a conference, and yesterday chatted with a friend. She said she struggles with staying present in life. Even while we were outside walking in a beautifully wooded area, she said she is always thinking of the next project, the next paper, etc.

This seems like a terribly stressful way to live.

Powers discusses ways in which his family has "offline time" on weekends, where they spend the entire time with each other instead of computing. Most people I know also seem to have developed certain rules for managing their technology. Like, "I don't use instant messenger at work", "I only check email after 6pm.", etc. This is certainly how I manage things, but perhaps due to occupational hazard I am more used to technology than most, and thus it's easier for me to ignore it.

The trick, I think, is to manage things in such a way that you can attend to the important things (i.e., your co-author needs your feedback by tomorrow), and disregard the unimportant things (i.e., the latest old spice guy video). Sadly all this technology is designed to trick our sensation-seeking brains into thinking every piece of information we receive is equally important, and sets it off into fire-fighting mode every time it dings/flashes/buzzes.

Speaking of which, back to meatspace...
