"While playing around with the Nmap Scripting Engine (NSE) we discovered an amazing number of open embedded devices on the Internet. " After completing the scan of roughly one hundred thousand IP addresses, we realized the number of insecure devices must be at least one hundred thousand. Starting with one device and assuming a scan speed of ten IP addresses per second, it should find the next open device within one hour. The scan rate would be doubled if we deployed a scanner to the newly found device. After doubling the scan rate in this way about 16.5 times, all unprotected devices would be found; this would take only 16.5 hours. Additionally, with one hundred thousand devices scanning at ten probes per second we would have a distributed port scanner to port scan the entire IPv4 Internet within one hour. [more inside]
In December, the Philadelphia police department released a csv database of major crimes (murder, rape, burglary, etc) since 2006. Since then, community software developers have been mapping the data. The community involvement is hoped to spur the future release of large city data sets. [more inside]
The Brookings Institution’s Metropolitan Policy Program (led by Bruce Katz) has just released its The State of Metropolitan America report (full pdf). The report builds on eight years of the Census Bureau’s American Community Surveys; and includes a spiffy State of Metropolitan America Indicator Map of changes in population indicators at state, metropolitan, and suburban levels.160;160; Some interesting findings:
- America's suburbs are now more likely to be home to minorities, the poor and a rapidly growing older population as many younger, educated whites move to cities for jobs and shorter commutes.
- Two-thirds of primary cities in large metropolitan areas grew from 2000 to 2008
- For the first time in several decades, the population is growing at a faster rate than households, due to delays in marriage, divorce and births as well as longer life spans. People living alone and nonmarried couple families are among the fastest-growing in suburbs.

Knowledge, in Real Time. "A new picture of science — and possibly future innovation — comes into focus with the mapping of scientists’ online research behavior."
Two visualization projects: All of the streets in the lower 48 United States: an image of 26 million individual road segments. No other features (such as outlines or geographic features) have been added to this image. And zipdecode, a unique map of US zipcodes.
