The media strategy that seems to be driving Jeff Bezos to make mobile consumption devices (with Amazon's media stores and Prime video/music) is flawed. No one makes money selling media for consumption anymore. That market is quickly and brutally dying. The media market is now so efficient that all profit is completely sucked out of the equation by the time you get to the consumption delivery system, to the point that it is barely possible to break even."
All nuclear reactors will generate waste via activation as the materials of which they are constructed erode and become unstable under high neutron flux. I'm not pointing this out because I think it's a big deal — a few fusion advocates disingenuously tend to sell the process as if it were "100% clean." A low volume of non-recyclable waste from fusion reactors that is walk-away safe in ~100 years is doable. Let's do it. And likewise, the best comparable waste profile for fission is a two-fluid LFTR, a low volume of waste that is walk-away safe in ~300 years. Let's do it.
Why pursue both, with at least the same level of urgency? Because both could carry us indefinitely. LFTR is less complicated in theory and practice. It is closer to market. There is plenty of cross-over: LFTR's materials challenges and heat engine interface — and the necessity for waste management — are the same as they will be for commercial-scale fusion reactors. To get up to speed please see the 2006 fusion lecture by Dr. Robert Bussard on the Wiffle ball 6 plasma containment, likely the precursor to the Skunkworks approach. And see Thorium Remix 2011 which presents the case for LFTR.
Those traveling regularly will enjoy better support for time zones in the panel's clock, while those staying at home a revamped clipboard manager, allowing you to easily get at your past clipboard's content. The Breeze widget style is now also available for Qt4-based applications, leading to greater consistency across applications. The work to support Wayland as display server for Plasma is still ongoing, with improved, but not complete support in 5.1. Changes throughout many default components improve accessibility for visually impaired users by adding support for screenreaders and improved keyboard navigation. Aside from the visual improvements and the work on features, the focus of this release lies also on stability and performance improvements, with over 180 bugs resolved since 5.0 in the shell alone."
