Configuring a Windows PC For a Senior Citizen? 823

An anonymous reader writes "I would like to know if there are any resources on the Web or elsewhere describing how to configure a Windows PC for an older parent not living in the same household. Assume little computer familiarity or aptitude. Some stuff is obvious, like using only a few large icons for favorite Web sites, or an icon perhaps for composing email and another for checking email. Other considerations are eliminating nuisance messages from Windows update and antivirus/firewall. What works and what doesn't? Can anyone who has worked/volunteered at a senior center offer some insights?"

Submission + - Taking STM images 100 times faster

Roland Piquepaille writes: "Very few of you have used a scanning tunneling microscope (STM), an essential tool to study nanoscience. And you might think that it's as easy to take a picture of an atom with an STM as it is to take a shot with your digital camera. In fact, the imaging of individual atoms with a STM is awfully slow. But now, U.S. researchers had a very simple idea to accelerate this process. By adding a simple radio transmitter, they are able to make atomic-level microscopy at least 100 times faster. A typical STM has currently a sampling rate of about one kilohertz. This new radio-frequency scanning tunnelling microscopy can operate a thousand times faster. Very bright idea! But read more for additional details and a picture of a scanning tunneling microscope. I'm sure it's different from your expectations."
