Sunspots Return 276

We're emerging from the longest, deepest sunspot drought since 1913 (we discussed its depths here) with the appearance of a robust group of sunspots over the weekend. Recently we discussed a possible explanation for the prolonged minimum. The Fox News article quotes observer Michael Buxton of Ocean Beach, Calif.: "This is the best sunspot I've seen in two years." jamie found a NASA site where you can generate a movie of the recent sunspot's movement — try selecting the first image type and bumping the resolution to 1024.

Four Missed Opportunities for Privacy 67

The NY Times has a blog posting on the occasion of the Internet advertising industry's release (PDF) of what it describes as tough new standards governing the collection and use of data about users' behavior. The Times' Saul Hansell describes these "new" standards as more of the same old status quo, and outlines four privacy-enhancing ideas, being discussed by Google, Yahoo, the FTC, and Congress, that the IAB has completely ignored. These principles are: every ad should explain itself; users should be able to see data collected about them; browsers should help enforce user choices about tracking; and some information (medical and financial) is simply too sensitive to track.
