Gas Wants To Kill the Wind 479

RABarnes writes "Scientific American has posted an article about the political efforts of natural gas and electric utilities to limit the growth of wind-generated electricity. Although several of the points raised by the utilities and carbon-based generators are valid, the basic driver behind their efforts is that wind-generation has now successfully penetrated the wholesale electricity market. Wind was okay until it became a meaningful competitor to the carbon dioxide-producing entities. Among the valid points raised by the carbon-based generators are concerns about how the cost of electricity transmission are allocated and how power quality can be improved (wind generation — from individual sites — is hopelessly variable). But there are fixes for all of the concerns raised by the carbon-based entities and in almost all cases they have been on the other side of the question in the past."

Privacy With a 4096 Bit RSA Key — Offline, On Paper 232

HavanaF writes "Online backup is practical, but can it offer any privacy? The Dutch security company Safeberg developed an Offline Private Key Protocol, with an asymmetric key scheme. The protocol demands that the private (decryption) key be stored away from the 'source' computer, which presumably is 'too vulnerable.' The catch is that the private key needs to be fairly large to be secure: a 4,096-bit RSA key should suffice for some years. But how to store an 800-character key offline? Safeberg introduces a machine readable paper key, with the 4k-bit key crammed in a giant 2D Datamatrix barcode. This video on key strength tells the story."
