Augmented Reality and Privacy
Posted by kdawson on Monday November 30, @08:04AM from the case-for-a-protected-feed dept.
An anonymous reader recommends a piece up at Augmented Planet that makes a couple of points about privacy in the realm of geotagging and augmented reality that haven't been discussed much. First, once you geotag and upload, say, a photo to the Net you can lose ownership over the data and especially its metadata. Second, data on the Net is long-lived and might be put together in ways you wouldn't like, long after it was created.
"If you geotag a picture with your new 50" plasma TV in the background and upload it to the Web, congratulations you have just told everyone where you live and what you have of value. The web has a long memory — geotag something today and in six months it is still on the Web. When you tweet from the beach in Barbados telling your friends you are away for 2 weeks, that picture of your 50" plasma will still be out there along with its location. It's easy to track down someone's home address if you have their real name."
The submitter adds, "I never really cared about my online privacy too much. This article made me think seriously about privacy for the first time. No mean feat."
Perhaps East Anglia's promise to release all the data was a bit misleading. I may have my Stat students examine some of the data – next time I teach Statistics.
Where the Global Warming Data Is
Posted by kdawson on Sunday November 29, @09:04PM from the premiere-cru dept.
Several readers noted the latest fallout from the Climate Research Unit's Climategate: the admission by the University of East Anglia that the raw data behind important climate research was discarded in the 1980s, "a time when climate change was seen as a less pressing issue" according to the Times (UK) article. The Telegraph quotes Phil Jones, beleagured head of the CRU: "Our global temperature series tallies with those of other, completely independent, groups of scientists working for NASA and the National Climate Data Centre in the United States, among others. Even if you were to ignore our findings, theirs show the same results. The facts speak for themselves; there is no need for anyone to manipulate them." Some of the data behind these other results can likely be found in a new resource that jamie located up at the Real Climate site: a compilation of links to a wide variety of raw data about climate. From the former link:
"In the aftermath of the CRU email hack, many people have come to believe that scientists are unfairly restricting access to the raw data relating to the global rise in temperature. ... We have set up a page of data links to sources of temperature and other climate data, codes to process it, model outputs, model codes, reconstructions, paleo-records, the codes involved in reconstructions etc."

Climate Change Is Inevitable — It’s Time to Adapt
By Spencer Reiss November 9, 2009 5:33 pm Wired Dec 2009
… As many of the participants—certainly the scientists—are only too aware, the global war on carbon has not gone well for the atmosphere. The really inconvenient truth: We’re toast.

CO2 not the only gorilla in the room
Climatologist James Hansen of NASA published a paper last year in which he calculated that the atmospheric CO2 levels today are similar to what they were when the planet was ice-free 100,000 years ago. [So does CO2 cause “no ice” or does “no ice” cause CO2? Bob]
That's what this article seems to suggest.

What made CO2 so high HOW long ago?
http://news.mongabay.com/2005/1124-climate.html
Carbon dioxide level highest in 650,000 years
Or maybe much longer?

Last time carbon dioxide levels were this high: 15 million years ago, scientists report
Maybe it's a recent phenomena?

Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age-- a time when much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.
Another fun statistics project. Why are some counties 3 times the national average and my old home town in a county a 1/10th the national average?

… Start by choosing the scene, then the characters and then pick the expression. Also decide the way you want the character to move and add your voice (which I think is pretty cool ). For some characters, you can also modify the looks and the attire. Add various effects and save your video.
