Lie Factor: Dear Gizmodo, Popcorn isn't THAT expensive

Recently, I stumbled on an article over at Gizmodo about the exorbitant price of popcorn. To sum up the article in a couple of bullet points:
• A movie ticket in 1929 was $4.32. A ticket in 2009 is $7.20 - A price increase of 66%
• Popcorn in 1929 was $0.62. Popcorn in 2009 is $4.75 - A price increase of 666%

Below is the graphic created to represent the data:
It's a fun and flashy graphic that shows cost increases in popcorn and ticket prices. Unfortunately, from an information visualization perspective it is awful. In fact, the image is a good example of how graphics can be (un)intentionally misleading and manipulative.

First, how does the graphic represent the data? The increase in cost between the 1929 and 2009 images is shown by an increase in the height of the ticket and popcorn images. The problem is that if Gizmodo was going to demonstrate the information in this way, they should not have scaled the images proportionally. Why? While we are primed to accentuate the vertical dimension of the image, the truth is that the area of the image plays a large role in how we digest the information.

Edward Tufte says this about visualizing information:
The representation of the numbers, as physically measured on the graphic itself, should be directly proportional to the quantities represented.

So how badly does Gizmodo violate this rule? I decided to extract each image from the graphic and measure the area. To be fair, I removed the images with the equivalent of a square cookie-cutter, so my calculations might be slightly exaggerated... but I think you'll get the point.

Instead of a 66% cost increase for movie tickets, the graphic shows us a 166% increase for movie tickets.
Instead of a 666% cost increase for popcorn, the graphic shows us a 4500% increase for popcorn.


That is awful. And whether it was intended or not, the graphic is deceptive. Another way we can measure this is looking at the lie factor - the proportion of the data compared to the proportion of the visualization. A truthful visualization has a lie factor of 1. Generally, somewhere between 0.8 and 1.2 is considered tolerable.

The movie ticket graphics have a lie factor of 2.5.
The popcorn graphics have a lie factor of 6.75.

Ouch. To preserve the truthfulness of the graphic, I tweaked the visualization to be more like a bar graph (which preserves the data):
Looks a little bit different, doesn't it? The contrast between the two popcorn graphics doesn't look quite as extreme anymore. The point is still made, but this time with a kernel of truth.

Unfortunately, there is another problem with the graphic - it fails to tell the story. The whole point of the article is that the cost of popcorn has increased dramatically more than the cost of a movie ticket. The graphic is comparing the price of popcorn and a movie ticket in 1929 vs. the cost of popcorn and a movie ticket in 2009. Instead, it should be comparing the cost increase of a movie ticket vs. popcorn. I created one more simple bar graph to show this relationship:
Wow. For me, this visualization is the most stunning of all. It is simple and uncluttered - yes - but more than that, it drives home the point in convincing fashion. The point is that we don't need flashy graphics to tell a good story. To be clear, I'm not opposed to using images as long as they preserve the data. In fact, contrary to some visualization experts, I think we make a deeper connection with the data when it has aesthetic appeal. But the takeaway is this: Good data and good relationships tell a good story all by themselves.

InfoStream Visualizations: Goals and Priorities

(Note: If you haven't read my previous post: I Need You: Twitter, Information Overload, and Work Flow, you might want to give it a quick run through before you continue.)

After laying out the foundations of my project in the last post, I've been doing quite a bit of reading, questioning, and researching. Now it's time to lay out some goals and priorities to help constrain design process.

Overarching Design Goals:
1) Create visualizations of twitter streams (and more broadly, social network streams) that represent multiple layers of detail and abstraction.
Why? To prevent information overload and interruption. High level views should be "glance-able" - I should be able to get a general understanding of what is going on in the network through just a quick glance of the application.

2) Design these levels to smoothly transition from one to another. It should feel like a continuous transition instead of discrete, blocky states.
Why? The view will constantly be adjusting to your current state of focus, trying to limit distraction. The transitions themselves should not be distracting.


What is Important?
The difficult part in trying to create a birds-eye view is that we have to determine What is most important? What should we preserve at different levels? What best represents the community as a whole? Here is a list of priorities I have come up with for Twitter.

Replies/Direct Messages: This is seems pretty obvious, but I am going to be most interested in messages that are directly intended for me. They should be given a very high priority.. and most of their content should be preserved.
Community Value: Which messages are RT the most? Tweets that are considered most valuable to the community are often shared the most.
Community Trends: This is often demonstrated by "trending topics" on the Twitter search page. I'm sure that this largely corresponds to which messages are being RT the most, but I'm not ready to combine them just yet.
Locale: Messages that happen geographically close to me may be more interesting than those that occur 2,000 miles away. They open up the opportunity for meetings or events I'm interested in.
External Links: A lot of the content happens outside of the Twittersphere - blogs, news articles, YouTube videos. This shouldn't be completely lost in a representation of the community.
Interest Based Messages: This is a little tricky because I can't make a sweeping generalization about what a person's interests may be. For me, I always like reading about HCI, Boston, and the Bills. But the fact that my next door neighbor doesn't like the Bills shouldn't mitigate Terrel Owens newfound presence in my Twitter stream (For better or for worse).

A lot of thanks to @JesseNewhart 's YouTube video titled "How to Follow 15000+ People on Twitter Using these TweetDeck Tips". It helped me understand the process of someone who is forced to process an enormous Twitter stream.

Challenges:
Sweeping generalizations are dangerous: Representing a stream in a high-level visualization means that I have to do some generalizing. Unfortunately, this also means making decisions for people about what I think should be most important to them. I'm not sure this is healthy or helpful. Either a filtering or priority system should probably be included in the final design.

Transitioning from an overview to individual messages is difficult: I can imagine several visualization techniques that give beautiful overviews of some of the information listed in the previous section. I can even imagine the ability to zoom in and out of them to create multiple layers of detail. However, the difficulty comes in representing the deepest layer of detail: each individual tweet. How do I smoothly transition from a visualization to an individual message?

Your Input is Needed!
Get used to seeing a message like this at the conclusion of all my posts for this project. But it's true! I am trying to design visualizations for the Twitter community. Instead of trying to guess what you think and need, I'm asking you. Comment, send me a Twitter message, or send me an email (evanpeck [at] gmail.com). I want to hear from you.

I Need You: Twitter, Information Overload, and Work Flow.

Hello everyone!

I am beginning a research project to help moderate workflow and interruptions from services like Facebook, Twitter, Flickr, Digg, etc.

I need your help.

Most of you who have spread themselves across the larger social media world now seem to be gravitating towards clients that can gather your scattered piles of information and communication into one cohesive place. Instead of simply using TweetDeck, you might use an application that combines Facebook statuses, Twitter messages, email alerts, and more all in one. It makes sense.

Unfortunately, our social networks are getting too big. I recently downloaded AlertThingy and received a new alert every 2 seconds or so (And I am by no means a power Twitter user). This typically results in information overload. So that is one problem. The other problem is that applications like TweetDeck and AlertThingy are often background tools. They are usually not my main focus. Instead, I am trying to write a paper, or research visualization techniques, or have a conversation with a friend in the Midwest.


The conversations on Twitter can be distracting - the ultimate nemesis of productivity. Even worse, I may be chanelling all the RSS feeds of my favorite blogs, news sites, and social bookmarking outlets into the same funnell. But at the same time, I still value them. I still want to know what's going on. I still want to be nudged if something exciting happens. How can anyone get anything done?

Let's get to the main questions: What if I can visualize this information stream at multiple layers of abstraction? Think about Google Maps, where I can view the map at 2,000 feet up and get a general sense of the topology or I can zoom down to see the parked in driveway. What if we could do this with Twitter? If we can, it means that when I glance over at Twitter during a writing spree for a 10 page paper, I can quickly see whether something in the massive stream of information is interesting to me. Just at a glance. I don't have to read through the 25 messages on the screen (even if I did, I might have missed something important in the 26th message). It still might be a distraction... but a .5 second distraction is better than a 20 second distraction.. especially since those 20 second distractions often end up in endless spirals of links and chatter. No need to always tumble down the rabbit hole.

I need you.

And here is where I need you. I follow around 200 people on Twitter. It is a fair amount... but no where near the thousands or tens of thousands of users that others follow. Now, I know that you are not reading every message from every person in your TweetDeck screen. Whether you are doing it explicitly or not, you are filtering and prioritizing information. Maybe you look for certain avatars that represent certain people. Maybe you look for key words. Maybe you give priority to people who are located somewhere around you. Maybe you pay special attention to words that are currently trending in the Twitter world. Or maybe you start paying attention if someone starts tweeting more than usual.


I need to know what you look for when you glance through Twitter messages. That way, as I look to design different levels of visualization, I will be carving out topologies and not counting garden gnomes. You have valuable insights and opinions. Maybe you've even secretly thought of this sort of thing and have some ideas of what is should look like. Well, tell me.

After all, if I want to do things right, I might as well ask the people who really know about it.

Where is this going?- Future Implications

While the idea of visualizing Twitter at multiple levels of abstraction is interesting enough to me, I skimmed over one important question - How can an application know which level of visualization to use? That's where the foundations of my research group come in.

Right now, we are researching Brain-Computer Interfaces. The whole project reaches out into the future a bit, but one measurement we have been working on is mental workload. So depending on how much mental processing you are using on that term paper, we may be able to adjust the visualization of your information stream accordingly. Anyways, I won't go into too much detail, but if you want to know more, you can always go here and read about some of our work.

Another potential application comes from mobile devices. Higher level views of information will preserve screen real estate. It makes sense to use these sorts visualizations on the iPhone (or whatever your device of choice is). Get a lot of information quickly and in a small space. You might not get everything, but you can always choose to dive deeper.

So tell me what you think. Post your thoughts in the comments section, send me a tweet (@EvanMPeck) or even shoot me an email (evanpeck [AT] gmail.com). I'd love to hear your opinions.

Cheers!
Evan

Why No One Wants to Start Using Twitter

I'm currently reading a paper in which Jennifer Preece, a professor in the Information Systems Department at the University of Maryland, outlines three components of sociability to support social interaction online:

Purpose
People
Policies

Since my life has been intertwined in what is now an eight month experiment with Twitter, I can't help but putting the community into the scope of these terms. I think it helps explain why Twitter is unpopular to start using. The basic communicated purpose of Twitter is very weak.

Watch this brief introduction video to Twitter:







What do you get out of that? Twitter is for telling people I'm going to get a gallon of milk. Twitter is for telling people I'm going out for coffee. Twitter is for telling people I'm watching a movie. So Twitter is just for status messages? The profiles are weak, the ability to find your friends is weak, and the communication is constrained and limited. So basically, it's Facebook without everything that is interesting. It's no wonder that the majority of people view Twitter along these lines:





So what is it that actually makes Twitter interesting? Why do people prefer it over Facebook or MySpace? A second paper by Preece may help shed some light. She says that "defining the community's purpose is important so that potential participants can immediately find out about the communities goals."

What's the problem with Twitter?- The purpose and goals of the community are wildly different from the purpose and goals defined by the basic definition of Twitter.

Here is what makes Twitter interesting for me:
  • Professional contacts.
  • A living, breathing, always-active recommendation system - whether that means a restaurant in Boston, the best shoes to buy, or interesting blog to read.
  • Group discussion and dialogue about trending events.
  • The ability to mobilize for social justice, local charities, or even just personal help.
  • The ability to draw like-minded (and not so like-minded) people together in the real world for real events.
  • For spreading news fast, accurately, and with multiple perspectives.
  • Viewing the personal face of corporations and businesses (@pandora_radio, @comcastcares, etc.)
I don't think my list is anywhere near unique, but not a single one of those reasons are on the Twitter website (that I know of). I had to slowly and gradually learn each and every one. To be honest, I never would have started using Twitter if it wasn't for an off-the-cuff decision to attend Social Media Camp Boston on an uneventful summer afternoon.

I'm never going to join a community where its purpose is to let people know I'm buying a gallon of milk down at Shaws. Maybe Twitter ought to stop pitching it that way.

"Wouldn't we be better off without technology?"

I've been posed this question rather frequently lately.

Wouldn't we be better off just focusing on a close community, face-to-face interactions, and localized problems?

It is an important question to think about because it quickly cuts to why we really need technology. I'm not so sure we have always been responsible or reflective enough (which, by the way, is a wonderful goal of the current constructionist movement in education). In the past, I've tried to create intricate responses, and they usually result in intriguing dialogue - conversations swaying back and forth - every counterpoint resulting in a "yeah, but... "

But the more I think about the question, the more I'm beginning to realize that I'm not so sure the question is relevant anymore. Just like the moment when Frankenstein emerges from the dark cellars to first experience light, I don't believe we can comfortably retreat back to the cellar again.

Consider the following story:

Suppose a prince is born in a kingdom with a magnificent castle - the walls are a thousand feet high. In fact, the prince has never left their luxurious confines. He has never felt hunger. He has never seen hunger. He never longs for the outside. He is hardly even aware that there is an outside. For this prince, privilege is the norm - after all, it is all he has ever known.

Does the prince have a social responsibility to elevate the poor?

It's easy enough to say, Well, of course. But I would disagree. Were 14th century Europeans responsible for the well-being of natives living in the Americas? No. As far as they were concerned, there was no America. As far as the prince is concerned, there is no poor.

Now suppose that one remarkable day, the prince goes for a walk outside the gates of the castle. He sees pain and suffering. He sees injustice and iniquity. He sees the raw nerves of humanity. Can he shut the castle doors with any finality ever again? Can he ever go back to the way that things once were?

I know that I am only picking on one dimension of technology, but it is central to the way we view our cellphones and laptops. Innovation is closely coupled to communication and information. Like it or not, I believe we have passed a point of no return with our technology. We have opened the dusty, crimson curtains and ushered the entire world into our living room - in all of its unshackled beauty and unspeakable horror.

So we need to stop asking, How do we pack up and go home? It just isn't relevant. "Home" has extended to every corner of the globe. What deeply troubles me is the new question: What do we do now that we're here?

A New Lens for Media

In the past, I've been critical of technology's inability to provide us with deep insights about ourselves. I've also worried that too much of technology is designed as an inward spiral, forcing us deeper into the medium instead of encouraging face-to-face conversations. But this post is about a time where technology did offer an insight (or at least a good reminder), and it was a surprisingly optimistic one.

A little background.

Recently, I've become very aware that media makes me surprisingly pessimistic about the world. In a previous article, How We've Created A Culture Where Kids Need Facebook, I wrote about the increasing paranoia of parents in regards to protecting their children. But the issue extends much further than that. Did you know that there were 8,000 fewer homicides in 2005 than in 1991? Did you know that that in the early 90s more than 9.5 people of every 1000 were victims of a homicide, but in 2005 that number was reduced to 5.6? Did you know that teen pregnancy is more than 20% lower than 30 years ago?

But wait. I thought the world was going to hell in a hand basket. Aren't all teenagers sexual maniacs? Isn't Mr. Jones' gardening business only a convenient cover for a Joker-esque madness?

Isn't everyone a Joker these days? Photo by Jason Mouratides

My point isn't to make this country sound peachy and comfortable (we all know it's not). But I do hope to help us understand that our opinion of the average Joe has been severed by a dramatized, ratings-driven media (And yes, I mean Joe the plumber, miner, construction worker, and every other -er that was uttered during the presidential elections). Thinking about my own tendencies, I know that I can be quick to transform people on the street into villains worthy of cinematic scheming.

So where does social media come in? What have I found out? What has social media helped remind me?

People are overwhelmingly nice.

That's it. That's the big revelation.

It's not revolutionary. It's not terribly shocking. But it is refreshing. I don't corral a group of people on the street and ask for help. For most of us, anything beyond asking for directions is an exercise in the art of awkwardness and discomfort. But if the internet community is any indication of reality, then there is a significant crowd of people who enjoy helping, who want to have engaging dialogue, and who genuinely care.

Ask for directions in an active social network? I receive them within 30 seconds. Wondering what the best seafood restaurant is in Harvard Square? I have a general consensus within the next five minutes. I take this for granted. For me (and for a lot of us), the challenge is reminding myself that there are real people behind the profile pictures. The challenge is fully understanding that these are the same people that I walk past every day in the Boston Commons.

I think we've worked ourselves into a bit of a double standard without even realizing it. We look through the dark lens of media to distort our depiction of humanity, but don't let the positive examples have the same impact on our perception. It reminds me of a friend of mine who likes to wear his sunglasses both day and night - during day we look dark, during night we look black. I'm not pretending that everyone online is good. We all know they aren't. The problem is that we let the misfits ruin the fun for everyone.

The Challenge.

So why don't we ask for help more often? And I'm not just talking about the "I'm lost, help me find my way" type of help. I mean, the "Where can I get a good burrito?" type of help, or "Any good used bookstores around here?" type of help. Or lets extend the idea even a little further. Ask a stranger about that book he or she is reading. Tell a stranger a fascinating quote you stumbled upon.

I know, I know. That last bit sounds awkward. You were probably whispering in your head, I would never do that. But I want to whisper back, why not? I sit on the subway system and watch hundreds of people pretend like they are too busy to chat or even acknowledge each others' presence for 20 minutes each and every day. Then, they go home, turn on their computer, and start sending Tweets to an audience they've never met before. They start participating in a dialogue with complete and utter strangers.

And they love it.

Just keep pretending there is no one else there. Photo by Gustavo Verissimo

I'll be the first to tell you that, so far, I don't practice what I preach. I can be very shy around strangers. I tend to think, Well, I know he doesn't want to be bothered, so I won't bother him. But I will tell you this: I've started to look at people a little bit differently. I've always been the type of person that wants to "see the best" in people, but when I'm bombarded by suicide bombings, masochistic murders, and outright belligerence in the media, it is hard to really believe it. It is hard to let my thoughts sink into reality. Social media gives us a new lens through which we can view people with remarkable optimism - one where people (for whatever reason) feel compelled to demonstrate a friendly nature in outlandishly open ways.

And I don't know about you, but I sure wouldn't mind seeing that friendliness, that assistance, and that camaraderie trickle onto the real streets and highways of this country.

We're not quite there

A lot of people ask me the benefits of Twitter, especially in regards to face-to-face interactions. I have a list I can roll off, but often find myself answering "Well, we haven't quite arrived yet." And I think that is true. We aren't there yet. But we are moving closer.

Picture courtesy of Ryan Lane

The question is How do we encourage people to move outside the technology? Here is one idea:

I would like to see a locale-based Twitter system become successful. It would be great to harness the social power of Twitter and refocus it into physical locations. At the very least, it would create more face-to-face interactions. In addition, it could act as a fantastic tourism tool and the equivalent of a text-based two-way radio transceiver.

In a museum, we could discuss and suggest fascinating displays. In a city, we could give traffic alerts. In a concert, we could discuss the music. In an emergency situation, we could quickly organize ourselves. The list goes on.

In reality, Twitter is already being used for all of these purposes. Users tag and filter tweets to listen to a group at a conference or major event. But there are a couple of problems with this approach:

1) I need to somehow know the tag. This isn't always the case, especially in the scenarios I listed above. Even in a more organized situation like a conference, it takes awhile for the members to get on the same page. Tags go through a social darwinistic evolution where only the strong survive. In a less organized situation (a coffee shop), it is downright impossible to find out if anyone in the area is using Twitter.
2) Noise, noise, noise. Twitter is almost too general purpose. There are too many messages flying around. Although users can filter and listen to only a certain batch of tweets, they often don't. I believe that a constraint based system will push innovation within those boundaries.
3) Not sensitive to movement. Right now I'm at the MFA in Boston. But later, I may be at a Radiohead concert. Moving around forces the user to restart the whole process of finding the right tags or search terms.
4) Only good for densely populated areas. What I'm hiking and want to let the people in my vicinity know that there is a bear hunting near one trail. If I am using a Twitter based system, there is no good way to do this. None at all.

It doesn't seem like much of a stretch to create a locale based Twitter system. The technology is already here. The real challenge is making it succeed. Other evices have tried to use bluetooth for similar location communication. As far as I know, the bluetooth features are used sparingly at best. That's why I hope that by piggy-backing onto the wildly successful Twitter network, we might be able to take a second run at this problem.

What are the benefits? A Twitter network that impacts the real world in a deeper way than it already has. I believe it would encourage face-to-face interaction as well as act as a valuable collaboration tool.

Twitter has made a remarkable impact on news networks, media, and emergency communication systems. But it isn't quite there. This idea may help, but it won't solve everything. We need to continue to make it a priority to push the technology outward into our everyday lives.

Understanding Technology Policy

With an Obama administration coming right on the heels of the New Year, there is a lot of technology policy on the table you should know about. Here are a couple of interesting reads:

Weighing a Broadband Stimulus Plan

A clip: "In today's deep recession, digital age advocates are trying to persuade President-elect Barack Obama to put billions into a nationwide broadband build-out as part of his planned economic stimulus package ... But how do we make sure that the billions aren't spent creating the 21st century equivalent of ditches to nowhere?"

A little background: The United States is embarrassingly behind other tech-savvy nations in broadband adoption. To over-generalize the situation, our internet is slower, more expensive, and less available than many countries in the world. If you are interested, The Internet Technology & Innovation Foundation has a separate article on the issue.

(click picture for a larger view)

Should Computer Science be Part of a K-12 Education?

A clip: "Computing education benefits all students, not just those interested in pursuing computer science or information technology careers," said Bobby Schnabel, chair of ACM's Education Policy Committee (EPC). "But students often do not have many opportunities to engage in rigorous computer science study at the K-12 level," said Schnabel, dean of the Indiana University School of Informatics. "To meet the nation's educational and professional needs in the face of insufficient numbers of undergraduates majoring in computer science, we need to work harder to increase interest at the K-12 level, and to expand the pipeline supplying the necessary workforce for an information-based economy."

A little background: The Association for Computing Machinery (ACM) is recommending that Obama insert Computer Science into basic K-12 Education. The ACM is "the world’s largest educational and scientific computing society." Anyone who does anything related to computing is probably part of this organization (including me). I tend agree with them, as CS encourages abstract thinking and problem-solving skills that are difficult for children to develop at the elementary level. Also, even a cursory knowledge of programming gives enormous power to students later on in their education. Anyways, read the article and decide for yourself. It probably won't be the last you hear of it.

Business Time

I have not chatted with you in awhile. For those of you who keep tabs on my writing, I apologize. My notebook is filled with two-sentence thoughts and blurbs, but none of them have been flushed out enough to write a full article. Lets get some coffee sometime. Maybe that will make up for it.

On that note, I'd like to change the pace of this place a bit. In the past, I've felt compelled (for no good reason) to write at least three, lengthy paragraphs before pushing the post button. Well, that is not working. And to be honest, that approach undermines some of my intentions for this space. I don't mean this to be a space where readers are drowned in one more over-opinionated voice. If you want that, turn on the news. Instead, this should be a place where thoughts and ideas, all of which may be raw and unpolished, can be gleaned and formed by someone else.

This isn't my job and I don't want to pretend like I hold authoritative views in the subject matter.

Some things to look forward to:
- Short, "wouldn't it be nice" technology ideas
- Lists of interesting articles I've been reading
- Launching pads to larger discussions
- The same sort of articles as before.

Have a wonderful Christmas season. Cheers!

How We've Created a Culture Where Kids Need Facebook.

Generation Y/Z needs Facebook.

You've read countless articles and press releases bemoaning the appeal of virtual networks to adolescent youth. We wonder why they communicate leaving Facebook messages instead of long conversations over campfires. We struggle to see the appeal of virtual networks over pickup baseball games in crackling autumn wheather. Our knee-jerk reaction is to revert back to the habits of every generation before us and vomit a phrase like "back when I was a kid," or launch into nostalgia saturated stories of running around the neighborhood, cliff jumping, and kissing girls under bleachers. 

photo by lunawhimsy

People are absolutely right when they say "back when I was a kid," but it isn't the kids that have changed. It's the world around them. Here are four reasons why "get out of the house and play" just doesn't work anymore. 

1. Kids don't have cars. This one isn't too revolutionary. In fact, there has never been a generation of Americans who had cars at 13 years old. So what's the difference? Most Americans don't live in tight-knit communities anymore. I grew up in suburbia, was voted "Most Personable" of my high school class, but was only within walking distance of a handful of my friends. "Best friends" aren't necessarily defined by locale anymore. Most teens can't see their friends without car rides, or long bike rides (but ....).
2. Parents don't trust the world. The last 50 years has seen an increase in one of the most terrible epidemics of American society - freakishly over-protective parents. Don't go anywhere far. Don't go anywhere alone. Don't go anywhere late. Don't go anywhere early. Don't go anywhere without phone numbers. Don't go anywhere without supervision. Don't go anywhere without knee-pads, a helmet, and protective entourage. Half of our American teenagers are practically under house-arrest. 
3. The world doesn't trust teenagers. Name a place where all the local teenagers hang out. Nope. Nope. Well, they used to go there. The reality is that many businesses have banned tribal packs of hormones from their premises. The mall used to be a popular gathering place, but apparently the collective whole of Generation Y is a lying, rude, shop-lifting punk. Oh, and those tattoos don't mesh well with other paying customers. By all measures, I was a good kid in high school, and I can still remember numerous "get out of here" chats with local police. 
4. Many teens are over-scheduled. What is high-school for? I'll tell you what it's for - leading 15 clubs, participating in 3 varsity sports, maintaining a 4.0 GPA, and serving the community for 20 hours a week. That way you can go to a good college and have a good life (affording college may be the real issue here). Teens are increasingly over-committed. It is near impossible to coordinate the chaos of 10 conflicting schedules. 

What does this all mean? 
So far, we've concluded that teenagers don't have a place to go, a way to get there, or even time to spend there. If by some minor miracle they have all three of those requirements, they may not be allowed to go. But one thing hasn't changed - teenagers still desire community. If I did an informal poll, I woudn't be surprised to see it fall somewhere between ending poverty and establishing world peace. 

So where can teens go to form some semblance of community that can be controlled, that isn't in a physical location, that is away from disapproving adults, and that can be done in short 10 minute packages?

Facebook. MySpace. Twitter. Social Media. 

I'm not saying it's good. I'm not saying it's bad. In fact, there are plenty of teenagers who can go anywhere and do anything, and still spend absurd amounts of time on Facebook. I'm just saying that our culture hasn't created messed up teenagers (at least not more messed up than any other generation), it has created a messed up environment that they live in. The teenagers are simply adapting in the only way they know how.

Undergraduate Street-Smarts (Part 1)

Your professors won't make you succeed, even if you do everything they tell you to. They will give you tools, give you lectures, and give you knowledge, but it isn't enough. I've collected some of the most important things I've done/wish I had done during my undergraduate years. 
Don't just be an academic. Have academic street smarts.

1. Join your professional association.

For CS students, join the ACM - something you can do the first day of college. It may cost you a few bucks, but it's worth it.

Why? Access to tremendous resources, the opportunity to keep a watchful eye on your field, and a resume check mark which shows that you engage in your field. It may also give you a heads up for interesting speeches and conference. More on that later.

2. Make a "net presence" for yourself.

Sadly, this revelation came to me only after my graduation. Create a Twitter account and find people to follow in your field. Create a LinkedIn account and start making connections. Create a blog. Even if you update it once a week, write a paragraph about what you are thinking about.

Why Twitter? Think of Twitter as a more productive instant message. If you follow the right people you a) get up to the minute updates in your field (or points of interest) and b) are suddenly included in a network with "all the right people." Bonus: There are lots of Twitter gatherings at restaurants that can give you an opportunity to get face time with influential people (at least, more influential than you). Networking, networking, networking. 

Why LinkedIn? LinkedIn is a professional Facebook. There aren't wall messages, there are recommendations. You don't post music, you post your resume. Even more crucial, important people use LinkedIn, not just your college buddies. More networking, more connections = good.

Why Blog? Since I've started blogging, not only has it increased my awareness in the field, but it has made me more articulate when I speak about issues that are relevant to my area of study. Need another good reason? Many top-notch graduate schools don't even have time to interview you. Their only exposure comes through your application. If you have a blog, you create an opportunity for graduate schools to hear more of what you have to say. I found that some applications didn't cater to my strengths at all. It is good to have a place that does.

Overall Why? If I say the name "Barack Obama", you know who it is. Why? It is because his face, his words, and his opinions are everywhere. The names you know are the names you see. Expand your network and give yourself a soap box to stand on. Even if think you don't have anything important to share, start building connections for when you do. I have been fully engaged with social media for only a couple months, but Googling Evan Peck now lays me claimto 6 of the top 8 entries on the results list. Not bad. Once you have found something you really want to say, you'll want that public arena, so start building it now.

3. Take Some Writing Courses
I don't care what you do. Your major doesn't matter. Learn to write well. The better you write, the more people pay attention. Take a poetry class. Take a fiction class. Take a non-fiction class.

Why? As a computer science graduate student, surveying the writing proficiency in the field is pathetic. It's one thing to write so that your colleagues understand it (and sadly, this is enough of a challenge for many people), it is another to write so that it is accessible to the larger public. If 1,000 people are excited about an idea, it moves a lot quicker than if the 10 people in your class think it's cool. To put it simply: Ideas don't go anywhere if they aren't communicated well. If you want to go to grad school, you'll be writing journal articles. As I mentioned ealier, a graduate school's only exposure to you as a person comes through your personal statement. You'd better be capable of making it good. 

4. Learn Basic Design Principles.
I cannot stress this enough. Don't be the guy who uses Vegas colors. Don't be the guy who uses Comic Sans in his papers. If you can take a class, fantastic. If not, just take some time to look over design portfolios online. Try to learn a little about typography.
Focus on simplicity.

Why? It is downright amazing how great ideas can be sunk by terrible design. Personally, it's much harder for me to respect an application if it has a poor visual design, even if it is functionally perfect. We are visually inclined. That's why we like sunsets and deep canyons. It's why attractive politicians do better than unattractive ones (sad, but true). So design well, or at least, make friends that can design well.


5. Present Well. Present Often.
Present every chance you get. If you are in collaborative projects, offer to be the speaker. Create lots of PowerPoint presentations. Take a public speaking class. Present in comfortable situations, then present in uncomfortable situations. Present on things you know about and present on things you know absolutely nothing about. 

Why? You should present well for many of the same reasons you should write well. You become exponentially more valuable if you a strong presenter. I've seen whole hordes of people get excited by terrible ideas that were presented brilliantly. Presenting well also means that you get to meet more people - you get to go to more conferences, you get more face time in front of key individuals, and you can even excite people outside of your field's sphere of influence. Take the opportunity to hone those skills now, when presentations in front of 15 half-awake students don't matter. Experiment a bit and see what works. 

Hope you enjoyed the post. If you have any thoughts of your own, let me know.

Poetry in Technology

Let's continue to be innovative in the way we present our art.

A couple of hours ago, I was digging around some of the poetry I wrote for an undergraduate class. There was one file that stuck out - David and I are not so different. Is it my best work? No. It was a result of one blistering hour at Panera - free-form, loosely structured, and stream-of-conscious writing at it's best.

But I remember wishing that the line-breaks would be more prominent. I wanted a breath between words, or some way to tell my reader "sit on these awhile". I was never satisfied with the result.

Tonight, I tried something different. I took the same poem and tossed it in PowerPoint. I translated stanzas into different slides. I tore out subtle pauses and made them visually evident. I tried not to mess with the typography and design too much, but you'll see that there were a couple of times where I just couldn't help myself. The point of this exercise is less a visual experience and more an experiment of pacing.

So sit back and enjoy.
(Note: Please use full-screen mode. I think it is much more immersive)


How did it work for you?

Get Unplugged

There are short sentences outside of Twitter.
There are people outside of YouTube.
There are LOLs that shake bellies.
There are fights outside CAPS.
There are favorites without bookmarks.
There are friends outside Facebook.

There is beauty outside. Just outside.

Obama on Science

It's time to take a break from questioning pregnant 17 year olds, fuming over Focus on the Family prayers for political intervention, and wondering whether Alaska should really count as being part of the United States. Believe it or not, some of the candidates have something to say. Even more surprising, it won't ever hit tabloids (which makes America wonder whether it is really something worth saying at all).

Cynicism aside, Barack Obama recently responded to "The Top 14 Science Questions Facing America". These questions were narrowed down from a pool of 3,400 and cover the scientific landscape quite well. Despite being a well-known muslim, elitist terrorist who has a 63% chance of transforming into the anti-Christ (which could happen at any mom
ent), I appreciate the time Senator Obama spent to respond to these questions. 

For your reading pleasure, I've taken the questions which I believe are most relevant to this blog, and reposted them - questions concerning technology, education, and research. I'd encourage you to take some time to read all of Barack's responses. I've long believed that science will dictate the moral and ethical future of our nation. To be fair, I will also post McCain's thoughts once he responds to the questions. 

Enjoy!

1. Innovation. Science and technology have been responsible for half of the growth of the American economy since WWII. But several recent reports question America’s continued leadership in these vital areas. What policies will you support to ensure that America remains the world leader in innovation?

Ensuring that the U.S. continues to lead the world in science and technology will be a central priority for my administration. Our talent for innovation is still the envy of the world, but we face unprecedented challenges that demand new approaches. For example, the U.S. annually imports $53 billion more in advanced technology products than we export. China is now the world’s number one high technology exporter. This competitive situation may only worsen over time because the number of U.S. students pursuing technical careers is declining. The U.S. ranks 17th among developed nations in the proportion of college students receiving degrees in science or engineering; we were in third place thirty years ago.

My administration will increase funding for basic research in physical and life sciences, mathematics, and engineering at a rate that would double basic research budgets over the next decade. We will increase research grants for early-career researchers to keep young scientists entering these fields. We will increase support for high-risk, high-payoff research portfolios at our science agencies. And we will invest in the breakthrough research we need to meet our energy challenges and to transform our defense programs. 

A vigorous research and development program depends on encouraging talented people to enter science, technology, engineering, and mathematics (STEM) and giving them the support they need to reach their potential. My administration will work to guarantee to students access to strong science curriculum at all grade levels so they graduate knowing how science works – using hands-on, IT-enhanced education. As president, I will launch a Service Scholarship program that pays undergraduate or graduate teaching education costs for those who commit to teaching in a high-need school, and I will prioritize math and science teachers.  Additionally, my proposal to create Teacher Residency Academies will also add 30,000 new teachers to high-need schools – training thousands of science and math teachers. I will also expand access to higher education, work to draw more of these students into science and engineering, and increase National Science Foundation (NSF) graduate fellowships. My proposals for providing broadband Internet connections for all Americans across the country will help ensure that more students are able to 
bolster their STEM achievement.   

Progress in science and technology must be backed with programs ensuring that U.S. businesses have strong incentives to convert advances quickly into new business opportunities and jobs. To do this, my administration will make the R&D tax credit permanent. 

4. Education.  A comparison of 15-year-olds in 30 wealthy nations found that average science scores among U.S. students ranked 17th, while average U.S. math scores ranked 24th.  What role do you think the federal government should play in preparing K-12 students for the science and technology driven 21st Century?
 
All American citizens need high quality STEM education that inspires them to know more about the world around them, engages them in exploring challenging questions, and involves them in high quality intellectual work. STEM education is no longer only for those pursuing STEM careers; it should enable all citizens to solve problems, collaborate, weigh evidence, and communicate ideas. I will work to ensure that all Americans, including those in traditionally underrepresented groups, have the knowledge and skills they need to engage in society, innovate in our world, and compete in the global economy. 

I will support research to understand the strategies and mechanisms that bring lasting improvements to STEM education and ensure that promising practices are widely shared. This includes encouraging the development of cutting edge STEM instructional materials and technologies, and working with educators to ensure that assessments measure the range of knowledge and skills needed for the 21st Century. I will bring coherency to STEM education by increasing coordination of federal STEM education programs and facilitating cooperation among state efforts. I recently introduced the "Enhancing Science, Technology, Engineering and Math Education Act of 2008" that would establish a STEM Education Committee within the Office of Science and Technology Policy (OSTP) to coordinate the efforts of federal agencies engaged in STEM education, consolidate the STEM education initiatives that exist within the Department of Education under the direction of an Office of STEM Education, and create a State Consortium for STEM Education. These reforms will strengthen interagency coordination at the federal level, encourage collaboration on common content standards and assessments for STEM education at the state and local levels, and provide a mechanism for sharing the latest innovations and practices in STEM education with educators. I also recently sponsored an amendment, which became law, to the America Competes Act that established a competitive state grant program to support summer learning opportunities with curricula that emphasize mathematics and problem solving. 

My education plan is built on the recognition that teachers play a critical role in student learning and achievement. My administration will work closely with states and local communities to ensure that we recruit math and science graduates to the teaching profession. Through Teacher Service Scholarships, a Teacher Residency Program, and Career Ladders, I will transform the teaching profession from one that has too many underpaid and insufficiently qualified teachers to one that attracts the best STEM teaching talent for our schools. 

We cannot strengthen STEM education without addressing the broader challenges of improving American education and other priority issues. In addition to a focus on high quality teachers, my comprehensive plan addresses the needs of our most at-risk children, focuses on strong school leaders, and enlists parent and community support. My proposals for a comprehensive “zero to five” program will ensure that children enter school ready to learn. And when they finish school, I will make sure that through the new $4,000 American Opportunity Tax Credit, they will have access to affordable higher education that will provide them with the science fluency they need to be leaders in STEM fields and across broad sectors of our society.

5. National Security.  Science and technology are at the core of national security like never before.  What is your view of how science and technology can best be used to ensure national security and where should we put our focus?
 
Technology leadership is key to our national security. It’s essential to create a coherent new defense technology strategy to meet the kinds of threats we may face—asymmetric conflicts, urban operations, peacekeeping missions, and cyber, bio, and proliferation threats, as well as new kinds of symmetric threats. 

When Sputnik was launched in 1957, President Eisenhower used the event as a call to arms for Americans to help secure our country and to increase the number of students studying math and science via the National Defense Education Act. That educational base not only improved our national security and space programs but also led to our economic growth and innovation over the second half of the century. Our nation is again hearing a threatening “ping” in the distance, this time not from a single satellite in space but instead from threats that range from asymmetric conflicts to cyber attacks, biological terror and nuclear proliferation. I will lead the nation to be prepared to meet this 21st- century challenge by investing again in math and science education, which is vital to protecting our national security and our competitiveness. 

As president I will also ensure that our defense, homeland security, and intelligence agencies have the strong research leadership needed to revitalize our defense research activities and achieve breakthrough science that can be quickly converted into new capabilities for our security. 

This year, I was encouraged to see the Department of Defense (DoD) requested a sharp increase in the basic research budget for breakthrough technologies. More is needed. My administration will put basic defense research on a path to double and will assure strong funding for investments in DoD’s applied research programs. We will enhance the connections between defense researchers and their war-fighting counterparts. And, we will strengthen defense research management so that our most innovative minds are working on our most pressing defense problems. A strong research program can also lower procurement costs by reducing technical risks and increasing reliability and performance. Renewing DARPA (the Defense Advanced Research Projects Agency) will be a key part of this strategy.

My administration will build a strong and more productive research program in the Department of Homeland Security (DHS) that will include critical work on cyber and bio security. Because existing programs have been plagued by management problems, we will bring a renewal of talent, organization, and focus, seeking support from our universities, companies, and labs. Another critical role for R&D in national security is energy. Our petroleum dependence continually threatens our security, and my proposals for accelerating new alternative energy technologies will be an important part of my national security R&D agenda. 

Finally, we will act to reverse the erosion of the U.S. manufacturing base - which could jeopardize our technical superiority. We need to continue to develop the finest defense systems in the world. But, we are losing domestic production capability for critical defense components and systems. I will implement the recommendations of the Defense Science Board on defense manufacturing, strengthen efforts at DoD’s Manufacturing Technology program, and invest in innovative manufacturing sciences and processes to cut manufacturing costs and increase efficiency.

12. Scientific Integrity. Many government scientists report political interference in their job.  Is it acceptable for elected officials to hold back or alter scientific reports if they conflict with their own views, and how will you balance scientific information with politics and personal beliefs in your decision-making?
 
Scientific and technological information is of growing importance to a range of issues. I believe such information must be expert and uncolored by ideology.  

I will restore the basic principle that government decisions should be based on the best- available, scientifically-valid evidence and not on the ideological predispositions of agency officials or political appointees. More broadly, I am committed to creating a transparent and connected democracy, using cutting-edge technologies to provide a new level of transparency, accountability, and participation for America’s citizens. Policies must be determined using a process that builds on the long tradition of open debate that has characterized progress in science, including review by individuals who might bring new information or contrasting views. I have already established an impressive team of science advisors, including several Nobel Laureates, who are helping me to shape a robust science agenda for my administration.  

In addition I will: 

• Appoint individuals with strong science and technology backgrounds and unquestioned reputations for integrity and objectivity to the growing number of senior management positions where decisions must incorporate science and technology advice. These positions will be filled promptly with ethical, highly qualified individuals on a non-partisan basis;
• Establish the nation’s first Chief Technology Officer (CTO) to ensure that our government and all its agencies have the right infrastructure, policies and services for the 21st century. The CTO will lead an interagency effort on best-in-class technologies, sharing of best practices, and safeguarding of our networks;
• Strengthen the role of the President’s Council of Advisors on Science and Technology (PCAST) by appointing experts who are charged to provide independent advice on critical issues of science and technology. The PCAST will once again be advisory to the president; and
• Restore the science integrity of government and restore transparency of decision- making by issuing an Executive Order establishing clear guidelines for the review and release of government publications, guaranteeing that results are released in a timely manner and not distorted by the ideological biases of political appointees. I will strengthen protection for “whistle blowers” who report abuses of these processes.

13. Research. For many years, Congress has recognized the importance of science and engineering research to realizing our national goals.  Given that the next Congress will likely face spending constraints, what priority would you give to investment in basic research in upcoming budgets?
 
Federally supported basic research, aimed at understanding many features of nature— from the size of the universe to subatomic particles, from the chemical reactions that support a living cell to interactions that sustain ecosystems—has been an essential feature of American life for over fifty years. While the outcomes of specific projects are never predictable, basic research has been a reliable source of new knowledge that has fueled important developments in fields ranging from telecommunications to medicine, yielding remarkable rates of economic return and ensuring American leadership in industry, military power, and higher education. I believe that continued investment in fundamental research is essential for ensuring healthier lives, better sources of energy, superior military capacity, and high-wage jobs for our nation’s future. 

Yet, today, we are clearly under-investing in research across the spectrum of scientific and engineering disciplines. Federal support for the physical sciences and engineering has been declining as a fraction of GDP for decades, and, after a period of growth of the life sciences, the NIH budget has been steadily losing buying power for the past six years. As a result, our science agencies are often able to support no more than one in ten proposals that they receive, arresting the careers of our young scientists and blocking our ability to pursue many remarkable recent advances. Furthermore, in this environment, scientists are less likely to pursue the risky research that may lead to the most important breakthroughs. Finally, we are reducing support for science at a time when many other nations are increasing it, a situation that already threatens our leadership in many critical areas of science. 

This situation is unacceptable. As president, I will increase funding for basic research in physical and life sciences, mathematics, and engineering at a rate that would double basic research budgets over the next decade. 

Sustained and predictable increases in research funding will allow the United States to accomplish a great deal. First, we can expand the frontiers of human knowledge. Second, we can provide greater support for high-risk, high-return research and for young scientists at the beginning of their careers. Third, we can harness science and technology to address the “grand challenges” of the 21st century: energy, health, food and water, national security, information technology, and manufacturing capacity.

Hurricane Gustav: If they can't do it, we will.

UPDATE (9.2.2008): ABC News just wrote an article about using social media as an emergency tool. It looks like the Gustav efforts really helped some people out. Good to hear.

Katrina. Gustav.

Gustav. Katrina.

The names are intertwined in a morbid marriage of past and future. Katrina: the natural horror which clawed at the bare nervous system of Louisiana. A failure to prepare, a failure to react. And then there is Gustav, looming over the coastal state with an air that smacks of inevitability.

If you want to be encouraged, visit Beth's Blog: How Nonprofits Can Use Social Media, Get Involved with Gustav Online Volunteer Efforts. It's a breath of fresh air, and a wonderful example of social media coordinating it's own disaster relief efforts.

Talk Together. Talk Loud. Talk About Poverty.

If a tree falls in a forest and no one is around, maybe it doesn't make a sound. But on October 15, 2008, over 20,000 trees are falling, and they plan to make a whole lot of people notice.

It's Blog Action Day 2008. And this is what it's all about ...



Can it make a difference? I think so.

In an interview the other day, I shared my worries about the effect technology has on the poor. Does it further the divide between the haves and have-nots? Does technology make those who don't have the opportunity to use it even weaker in a world that is increasingly dependent on it? Or do we celebrate the raised awareness? Do we celebrate that people can and do raise more money than ever because of that raised awareness? Do we celebrate that more people are taking an active role against poverty largely because of the connections and resources that technology has given them?

Talking won't solve everything. But it will get people involved. Here's a quick story:

In 2004, my friend (let's call him Jason) takes an evening trip to study in Boston, walking with noise-canceling headphones in the Fenway area. Jason has no clue that the Boston Red Sox are hosting the New York Yankees in the American League Championship Series. And to be fair, Jason doesn't really care. He has never liked baseball. Never cared about the Red Sox. Doesn't notice the New York Yankees. That is, Jason doesn't notice until he hears a sudden swell of noise. The noise rises over the Boston streets and cuts through the climax of "Karma Police" by Radiohead. Puzzled, he takes off his headphones and becomes engulfed by the sound of a David Ortiz home run, or a Dave Roberts stolen base off Mariano Rivera. 30,000 fans yelling. 30,000 fans screaming. The sound of 30,000 people happier than they've been in weeks.

"I love baseball." That's what Jason told me the next day. He was preaching to the choir, but that sure didn't help with my confusion. "I'm still not sure about the game, but anything that gets that many people that excited and that passionate, I have to love."



So pass on the word and yell a whole lot. Get people excited. Maybe, just maybe, the right ones will listen.
