How to get gigapixel photos from a cheap digicam - tech - 27 February 2009 - New Scientist

I mentioned yesterday that new technologies exist for super-resolution photography. One approach is known as Gigapan and uses a robotically-controlled  digital camera set on full zoom. The robotic system takes hundreds or thousands of pictures that are then stitched together to form a single super-high resolution image, on in which you can zoom in to any area to see details invisible in the full view, like the beachgoer invisible in the top (full-sized) image. Some people have even extended the gigapan principle to make 3D gigapans from stereo views of the scene.

Pseudo-science: Google Street View Captures Victorian Ghost Walking in Cardiff

This photo is believed by many to be a Victorian-era ghost, captured by Google Streetview. Personally, it looks like the result of a poor stitch between photos as a result of photomerge software not determining the correct shooter perspective. I see this all the time in Photoshop in situations were a photomerge is simply beyond the capabilities of the software. The give-away? Look at the distortion of the posts.
For amusement, I add the Google Streeview photo purported to be an alien and some kind of laser beam, from the "impeccable source" known as "Weekly World News" and written by someone calling themselves Erik Van Datiken. For those who miss the joke, Erik Von Daniken wrote dozens of books about how aliens were supposed to have influenced the evolution of the human race.

Canadian research uncovers cyber espionage network

Canadian researchers, investigating allegations that computers used by exiled Tibetans were hacked by the Chinese government, stumbled upon a far larger espionage network involving four servers, three in China and one in the US, and more than 1,295 infiltrated computers, many belonging to embassies, foreign ministries and other government offices. The infiltrated computers had malware installed that allowed the servers to gain root access the computers. With this, they were able to read files, check email, even remotely activate microphones and web cams. Most of the infected computers appeared to have been infected for more than a year by what is being described as a Trojan that it undetectable to current firewalls and anti-virus technology. The spy network has, for now, been dubbed GhostNet.
