cityhunter007 writes to point out coverage on CNN.com about an ancient village discovered two miles from Stonehenge that may have housed workers building the monument, or perhaps visitors after it was constructed. The village, at a site known as Durrington Walls, dates from about the time Stonehenge was built, 2600 BCE. The article says: "The researchers speculated that Durrington Walls was a place for the living and Stonehenge — where cremated remains have been found — was a cemetery and memorial... Stonehenge was oriented to face the midsummer sunrise and midwinter sunset, while the wooden circle at Durrington Walls faced the midwinter sunrise and midsummer sunset."

An anonymous reader writes "eWeek has a story describing a talk by former Microsoft developer Adam Bosworth, now a VP at Google, entitled 'Physics, Speed and Psychology: What Works and What Doesn't in Software, and Why.' Bosworth depicts issues with processing, broadband, natural language, and human behavior; and he dishes on Microsoft." Quoting: "'Back in '96-'97, me and a group of people... helped build stuff that these days is called AJAX,' Bosworth said. 'We sat down and took a hard look at what was going to happen with the Internet and we concluded, in the face of unyielding opposition and animosity from virtually every senior person at Microsoft, that the thick client was on its way out and it was going to be replaced by browser-based apps. Saying this at Microsoft back in '96 was roughly equivalent to wandering around in a fire wearing matches,' he said. 'But we concluded we should go and build this thing. And we put all this stuff together so people could build thin-client applications... Now you hear about AJAX all the time, but this was built in '97,' Bosworth said. Yet, AJAX failed for a variety of reasons, including some 'big mistakes.'"

Several readers wrote in to tell us, following up on the recent story of the shutting down of Hubble's main camera, that program engineers are now saying that the camera is probably gone for good. The trouble resulted from a short circuit on Saturday in Hubble's most popular instrument, the Advanced Camera for Surveys. NASA engineers reported Monday that most of the camera's capabilities, including the ability to take the sort of deep cosmic postcards that have inspired the public, had probably been lost. We'll be pining for more of those amazing images until the James Webb launches in 2013.
Update: 01/30 23:28 GMT by KD : Reader Involved astronomer wrote in with an addendum / clarification to this story: "I'm a grant-funded astronomer at the Space Telescope Science Institute (www.stsci.edu) in Baltimore. I am very concerned that the article conveys the wrong idea about HST. While HST's science capacity is diminished with the loss of ACS, HST lives on and will continue to produce world-class science, even before its servicing mission in Sept. 2008, which will upgrade the instrument suite with the most sophisticated imagers in history." Read on for the rest of his note.

SpaceAdmiral writes "New York City is developing a plan to allow images to be sent to 911 emergency operators from cellphones. This will likely give emergency operators better information to pass along to responders. They're also planning on implementing a program of street-corner video cameras, as seen in the city of London. According to John A. Feinblatt, Mayor Michael Bloomberg's criminal justice coordinator: 'The more information that the police have and the more quickly that they get it, the more likely that they are going to fight a crime.'" How practical do you think it is to expand this sort of project to cities across the country? Moreover, is it worth the expense?

skepsis writes "Recently there have been some stories on Slashdot claiming that Vista would downgrade the quality of audio and video for every application in a machine where protected content was running. One of the stories painted a scary scenario where a 'medical IT worker who's using a medical imaging PC while listening to audio/video played back by the computer' would have his medical images 'deliberately degraded.' A post has been put up on the Vista team blog explaining exactly how the content protection works, and it turns out the medical IT staff and audio pros can relax. From the post: 'It's important to emphasize that while Windows Vista has the necessary infrastructure to support commercial content scenarios, this infrastructure is designed to minimize impact on other types of content and other activities on the same PC. For example, if a user were viewing medical imagery concurrently with playback of video which required image constraint, only the commercial video would be constrained -- not the medical image or other things on the user's desktop.'"
