Home-Built Turing Machine 123

stronghawk writes "The creator of the Nickel-O-Matic is back at it and has now built a Turing Machine from a Parallax Propeller chip-based controller, motors, a dry-erase marker and a non-infinite supply of shiny 35mm leader film. From his FAQ: 'While thinking about Turing machines I found that no one had ever actually built one, at least not one that looked like Turing's original concept (if someone does know of one, please let me know). There have been a few other physical Turing machines like the Logo of Doom, but none were immediately recognizable as Turing machines. As I am always looking for a new challenge, I set out to build what you see here.'"

Entergy Admits 2005 Tritium Leak 385

mdsolar writes "The leaking Vermont Yankee nuclear power plant was hit last week by a whistleblower allegation that a previous tritium leak had occurred. Now the parent company, Entergy, has admitted the occurrence of at least one prior leak to the Nuclear Regulatory Commission. This is particularly significant for three reasons: because the leak occurred in pipes that company officials later testified under oath did not exist, because the Vermont Senate will likely soon vote to deny Entergy a needed approval to extend the power plant's license for another 20 years, and because President Obama just put taxpayers on the hook for new nuclear power plants in Georgia."

ln, especially with symbolic links has got to be high up on this list from my point of view.

You can hack around so many problems with a handful of carefully placed symlinks.
