"When are you environmentalist nuts start studying how the electrical grid actually works instead of having fantasies about how it should work."

While a agree with your sentiment about anit-nuke positions, I think your "study the grid" viewpoint is narrow-minded.

Power demand (and thus supply) fluctuates greatly throughout the day. I'm an M.E. I worked for FPL, who know runs three solar power plants. I know how the grid works and it's sad that we still have to match production to demand. Energy storage systems are long overdue. There are some in place including uphill reservoirs, flywheels and thermal salt storage, but we haven't arrived yet. Though I'm not sure if centralized or decentralized (panels on houses) is best, it's clear that grid storage is a necessary step that will enable much needed flexibility on our power grid.

Grid storage is no more a "fantasy" than splitting atoms. I personally like nuclear. And I like wind and solar. And geothermal. They could work together nicely as base plus spike production. After we move to grid storage and look back, our current system of ramp production to meet demand will seem ridiculous and truly ancient.

XP has been used as an embedded system on some large format scanners, printers, lab machines and other specialized hardware where I work. Other machines such as digital copiers have their own OS providing services such as SMB, FTP and other network services. Do you think these other OS's are somehow inherently secure and free of security holes? Why require embedded XP to have current updates and not the other embedded OS systems?

While I agree one should keep a cool head and I agree with your driving suggestions, you should understand that many of the roads here you could ice skate on. No gravel. So Salt. Not even snow. Just pure slick ice. There was absolutely NOTHING to get traction on. Short of having chains, no tire or drivetrain could help. I had the pleasure of sledding down a hill this morning despite inching forward carefully. Luckily, I got into some snow on the side and regained traction.

Wrong. MPEG2 (OTA is encoded with MPEG2) is certainly compressed and in my opinion is the worst offender when it comes to digital artifacts. AVC on the other hand looks much better even at lower bitrates. Despite using lower bitrates, content from online sources such as Netflix and Amazon look much better than OTA.
Cable companies also use MPEG2, but I think they recompress the streams and the look truly awful.
