After seeing his friend’s CoinStar receipt for 27 pounds of coins that equalled $256.14, Dan Kozikowski dug deeper and estimated what a pound of change is worth, on average.

Now, to finish out the analysis, let’s tie this back to weight. Fortunately, the U.S. Mint standardizes and publishes the weight of each coin here. With that in hand… drumroll please… we’d expect about 34.9 quarters, 19.8 dimes, 11.5 nickels, and 61.2 pennies in a New York pound of coins, for a total value of $12.00. A Boston pound is worth slightly less&mdsah;$11.81.

I love it when people analyze the everyday. (Although I’m sure CoinStar looks at distributions like this all the time for storage supply something or other.)

Alas, the coin distribution of Kozikowski’s friend didn’t quite match the estimate, as shown in the graph above. He attributes it to the friend spending quarters, dimes, and nickels before going to the CoinStar. There are only fewer quarters though and almost twice the expected count of dimes and nickels, so the model needs to be refined.

TraceMedia, in collaboration with the Oxford Internet Institute, maps language use across Wikipedia in an interactive, fittingly named Mapping Wikipedia.

Simply select a language, a region, and the metric that you want to map, such as word count, number of authors, or the languages themselves, and you’ve got a view into “local knowledge production and representation” on the encyclopedia. Each dot represents an article with a link to the Wikipedia article. For the number of dots on the map, a maximum of 800,000, it works surprisingly without a hitch, other than the time it initially takes to load articles.

This is part of a larger body of work from Mark Graham and Bernie Hogan, et. al, which focuses mostly on the gaps, specifically in the Middle East and North Africa.

There are obvious gaps in access to the Internet, particularly the participation gap between those who have their say, and those whose voices are pushed to the sidelines. Despite the rapid increase in Internet access, there are indications that people in the Middle East and North Africa (MENA) region remain largely absent from websites and services that represent the region to the larger world.

Other than ten-year population estimates, the United States Census Bureau annually collects information about how people live in the country through the American Community Survey. It’s an eleven-page survey [pdf] that asks about your housing situation, education, and job, and there are 60 Republican members of Congress who want to make this currently mandatory survey optional.

The ACS will reach 3.5 million households this year, using dozens of detailed questions—including asking about a household’s use of flush toilets, wood fuel and carpools—to determine the need for various government programs. The survey’s mandatory status, along with telephone and in-person follow-ups to initial mailings, helps keep response rates near 100%.

Now, 60 Republican members of Congress, including presidential candidate and Texas Rep. Ron Paul, are challenging the survey’s mandatory status, with a bill that would make it voluntary to complete the ACS. The push is fueled by privacy concerns and the very detailed nature of the questions.

Find the full details of the bill on the Library of Congress site. Things got interesting when I searched for this link.

The 72-year mark has arrived, and the United States Census released individual records from 1940 yesterday. So you can now, for example, see that J.D. Salinger lived at 1133 Park Avenue.

I thought this was a joke, but it appears GM really is using a “three-dimensional visualization system” called — wait for it — 3-D Visualization. It’s meant as a generalized tool to track progress of systems, and they believe it could reduce time to make system changes, leading to fewer warranty claims, by 33 percent.

3-D Visualization builds on GM’s Problem Resolution Tracking System. If a transmission case breaks on a durability test vehicle, a problem resolution report documents the problem, and its corresponding LEGO block goes on a LEGO board. The block color identifies the area on the vehicle and the block size denotes severity; the bigger the block, the bigger the problem. Each block has an identification number and date of discovery, and the board shows its progress from root cause to solution to outcome. 3-D Visualization is applicable to any process that has volume and aging.

There’s no mention of a computer link in the press release (seems like something worth noting), but it does look like there’s a cable coming out from the board. If that’s the case, I want one.

If you go to Google Maps right now, there’s an option in the top right corner for a Quest view. Click on that, and get the world in all its 8-bit NES glory. And great news: The map adventure is coming to an NES console near you. Just put in the cartridge, connect to the Internet via dial-up, and you’re off to the races. See the world like you’ve never seen it before.

So the Obama campaign posted this yesterday. Discuss.

As a project of the Knight News Innovation Lab, Timeline by Verite is an open source project that lets you make and share interactive timelines. It’s simple and customizable. Plug in your own data as JSON, or use the Google Docs template for an even faster route, and you’re good to embed. It’s also easy to grab source material from sites like Vimeo, YouTube, and Flickr. Score.

Stamen Design, in collaboration with Climate Central, shows major areas that could be affected by probable rising water levels in the not so far off future.

The context for this work is: while there are a great many papers, scientific studies, meteorological surveys and other things that fall under the rubric of things that normal people accept as true, there remains a persistent and nagging unreality to the idea that, in something like a normal human timescale, we’ll see and have to reckon with large-scale changes to the world as we know it. It’s one thing to say “the world is changing and all of us will have to deal with it.” It’s quite another to say “7.6% of the people and 9.1% of the homes may very well be underwater in Boston, and so you’ll need to start thinking about that pretty damn soon, is that cool?”

Boston, you better make friends with Kevin Costner. He is key to your survival.
