An anonymous reader writes On Thursday, Benjamin M. Lawsky, the superintendent of financial services, announced proposed regulations for virtual currency companies operating in New York. The "BitLicense" plan, which includes rules on consumer protection, the prevention of money laundering and cybersecurity, is the first proposal by a state to create guidelines specifically for virtual currency. "We have sought to strike an appropriate balance that helps protect consumers and root out illegal activity—without stifling beneficial innovation," he said in a statement.

He serves as an adviser on many government boards including the Digital 21 Strategy Advisory Committee, which oversees Hong Kong's long-term information technology strategies. His research work on the use of Artificial Intelligence has been honored with numerous awards, and his AI system keeps the subway in Hong Kong running and repaired with an amazing 99.9% uptime. Dr. Chun has agreed to give us some of his time in order to answer your questions. As usual, ask as many as you'd like, but please, one question per post."
An anonymous reader writes The much anticipated Xorg Server 1.16 release is now available. The X.Org "Marionberry Pie" release features XWayland integration, GLAMOR support, systemd support, and many other features. XWayland support allows for legacy X11 support in Wayland environments via GL acceleration, GLAMOR provides generic 2D acceleration, non-PCI GPU device improvements, and countless other changes. The systemd integration finally allows the X server to run without root privileges, something in the works for a very long time. The non-PCI device improvements mean System-on-a-Chip graphics will work more smoothly, auto-enumerating just like PCI graphics devices do. As covered previously, GLAMOR (the pure OpenGL acceleration backend) has seen quite a bit of improvement, and now works with Xephyr and XWayland.
KentuckyFC (1144503) writes The idea of negative mass has fascinated scientists since it was first used in the 16th century to explain why metals gain weight when they are oxidized. Since then, theoretical physicists have shown how it could be used to create exotic objects such as wormholes and the Alcubierre warp drive. But cosmologists' attempts to include negative matter in any reasonable model of the cosmos have always run into trouble because negative mass violates the energy conditions required to make realistic universes with Einstein's theory of general relativity. Now a pair of cosmologists have found a way around this. By treating negative mass as a perfect fluid rather than a solid point-like object, they've shown that negative mass does not violate the energy conditions as had been thought, and so it must be allowed in our universe. That has important consequences. If positive and negative mass particles were created in the early universe, they would form a kind of plasma that absorbs gravitational waves. Having built a number of gravitational wave observatories that have to see a single gravitational wave, astronomers might soon need to explain the absence of observations. Negative mass would then come in extremely handy.
