Neuroscience students at the University of California, San Diego made a music video parody of Daft Punk’s “Get Lucky.” It’s about gathering data in the lab. Graduate students are such nerds.

The Endomondo app lets you keep track of your workouts, namely running and cycling, so it records your location, and then estimates your speed, calories burned, and elevation changes. And workouts are set to public by default. Nikita Barsukov used the public traces to make some quick and dirty maps of workouts in major European cities. Above is Copenhagen.

I’m curious about how these compare to car traffic or social media usage. Are they opposites or are they roughly the same, corresponding to number of people who live in an area? And, of course, I want to know what this looks like for American cities.

As we’ve seen, there are more fatal car crashes during the weekend and summer months, which is some time between May and September in the United States. The Guardian took a different approach to look at road fatalities in Australia.

The bottom section is your standard bar charts that show an average, but on top are mini-simulations that represent the averages. Small cars move in the background and squares appear on top to at different volumes. I originally thought the cars actually collided with each square, but it looks like they’re independent of each other. Nevertheless, an interesting approach.

SMBC pokes fun at big “informational” graphics with a self-referencing graphic that displays 6 reasons why said graphic is useful.

It’s not so much the size as it is the non-information displayed as something worth knowing.

At least one of these things lands in my inbox per day, and it always surprises me. Do people still share these things? I mean, these non-information graphics were popular five years ago, and there was a novelty aspect, but I rarely see them in my feed these days.

National Geographic imagined new coastlines (and the cities that would go under) if all the ice melted, raising sea level by 216 feet.

There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58.

The light blue borders represent present day, and the land shows estimates. London, Venice, Bangladesh, and all of Florida would be submerged, and Australia would gain a new inland sea. Of course, estimates assume not much else changes. [via kottke]

We’ve seen what happens when you turn on a Roomba and track its vacuum path with long-exposure photography. The LED on top provides a point of focus, and the visual represents an odd blend of chaos and order. Above is what happens when you set different colored LEDs on seven Roombas and let them loose. Don’t miss all the other (clean) messes in the Flickr pool. [via Radiolab]

The Open Knowledge Foundation launched the Open Data Index, so you can see what data countries provide to their citizens.

An increasing number of governments have committed to open up data, but how much key information is actually being released? Is the available data legally and technically usable so that citizens, civil society and businesses can realise the full benefits of the information? Which countries are the most advanced and which are lagging in relation to open data? The Open Data Index has been developed to help answer such questions by collecting and presenting information on the state of open data around the world – to ignite discussions between citizens and governments.

Based on community editor contributions, the index assesses the availability of datasets such as transportation timetables, election results, and legislation, and provides a single-number score. The higher the score is, the more data a government makes available to the public. Of the 70 participating countries, the UK leads the way, followed by the United States and Denmark.

We know that millions of Americans move to different counties every year, and when you look at the net totals, you see a pattern of people migrate from the midwest to the coasts. However, look at migration across demographic categories, and you see more detailed movement. This was the goal of researchers at the University of Wisconsin-Madison, and they recently released their estimates, in map form.

The Centers for Disease Control and Prevention released their most recent cancer data a few days ago. It’s the numbers for 2010, which feels dated. However, the annual data goes back to 1999, across demographics and states, which makes this data worth a look. You can download the delimited files here.

A browser accompanies the release, as shown below. It’s really just that though, leaving analysis up to you, and it’s rough around the edges.

So if you’re looking for a weekend project, this is a good place to go. I’d probably start with the age breakdowns and work from there.

There comes a time late at night when your screen grows fuzzy and the code runs together. Mistakes happen, and with visualization, the bugs often manifest themselves into abstract images that sort of resemble data. The Accidental aRt tumblr highlights these visual mistakes through the eyes of buggy R code. Ooo, infinite rainbow.

The Simply Statistics unconference just started a few minutes ago. Tune in live below. (Or, catch the recorded version if you’re late.)

With a $250,000 grant from the Knight Foundation, Waldo Jaquith pushes forward with the U.S. Open Data Institute, an effort to link government data sources and organizations over the next year.

I’m convinced that we already have many of the right people, organizations and businesses working on open data in the United States. They just don’t know about each other. (The organization certainly won’t duplicate any of the efforts of the folks in this space.) And we have nearly all of the necessary software, but so much of it is only known within its narrow domain, despite its broad applicability. The institute will connect all of these entities, promote the work of those who are leading the way and provide supportive, nonjudgmental assistance to those who need help. We don’t have all the answers, but we know the folks who do. We want to amplify their message and connect them to new collaborators and clients.

This could be fun.

Betrand Russell: “Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.” Yann Pineill and Nicolas Lefaucheux demonstrate in the video above. An equation appears on the left, a diagram in the middle, and the real-life version on the right.

A Distributed Denial of Service (DDoS) attack attempts to disable a site or web service by sending a ton of requests from multiple sources. Essentially, the server buckles under the pressure. Sometimes this is done to silence sites that the attackers disagree with, or they might try to take advantage of business backends.

The Digital Attack Map, a collaboration between Google Ideas and Arbor Networks, shows current attacks and serves as a browser for past attacks around the world. Color and size indicate the type of attack and movement represents origins and destinations.

A quick animated look on the evolution of western dance music, a mixture and blend of various styles and cultures over time.

To make it easier to trace the threads of music history, we’ve created an interactive map detailing the evolution of western dance music over the last 100 years. The map shows the time and place where each of the music styles were born and which blend of genres influenced the next.

There’s a cartogram in the background and lines connect countries and styles. It reminds me of those dance step charts with the feet on them.

You’ve probably heard of the six degrees of Kevin Bacon. The idea is that you can name any actor and trace back to Kevin Bacon through actors who have worked together. Ben Blatt for Slate applied this idea to sports and put together an interactive that finds the number degrees between athletes. The fun part is that you can enter two athletes from different professional sports: basketball, football, and baseball.

What’s even more remarkable is that it’s possible to connect players who didn’t even play the same sport. Cross-sport athletes like Deion Sanders and Bo Jackson are exceedingly rare, and some combinations of sports are hardly seen at all. Of these 18 athletes, all but one—Bud Grant—played baseball as one of his two pro careers, proving either that the stars of the diamond are athletic enough to master other sports or that anyone athletic enough to play basketball or football can also handle baseball. Hockey is the opposite, as there has never been a pro hockey player who also played top-level basketball, football, or baseball. As a result, hockey is a closed system. But once you get off the ice, it’s possible to link every pro baseball, basketball, and football star.

I like how it only takes 18 players (well, actually probably fewer) to pull double-time to make this possible. To link Yao Ming (basketball) and Joe Montana (football), it only took six hops, with Mark Hendrickson as a link between basketball and baseball and Deion Sanders as the link between baseball and football.

Surprising? Kind of, but then again, in 2011, almost all pairs of people on Facebook could be linked with just six hops, too. The barebones interactive is still a lot of fun to play with though if you follow sports.

Reuben Fischer-Baum looks at the most popular girl names by state, over the past six decades.

Baby naming generally follows a consistent cycle: A name springs up in some region of the U.S.—”Ashley” in the South, “Emily” in the Northeast—sweeps over the country, and falls out of favor nearly as quickly. The big exception to these baby booms and busts is “Jennifer”, which absolutely dominates America for a decade-and-a-half. If you’re named Jennifer and you were born between 1970 and 1984, don’t worry! I’m sure you have a totally cool, unique middle name.

Like the trendy names and unisex names explorations, this series of maps is based on data from the Social Security Administration, which is surprisingly formatted and ready to use. If you’re looking to play around with time series data and simple state geography, the SSA site is worth a bookmark. [Thanks, John]
