jake_Don Superconductor news: What’s claimed, and how strong the evidence seems to be

It would not roll over continuously as it's affected by gravity as well. The heaviest part is at the bottom.

And if it's not completely superconductive, what stops it from not being completely magnetic? For all we know, only the thin part could be magnetic, being repelled from the magnet below.

1. In the video, they push the disc with a pen until it rolls over. They repeat it multiple times. It it were superconductive they could just position it in space without laying it on the magnets first.

2. The disc is not hovering.

3. The disc is damaged; one edge is thicker/heavier than the other. Thus causes the rolling. Notice that the heavier part always stays on the magnet. It it were superconductive they would be able use a uniform disc.

I call BS.

jake_Don Annual income of richest 100 people enough to end global poverty four times over

The underlying assumption of the above headline is that the same amount of goods will be produced, even if you take the rich'es revenues away from them. Well, false. Without proper incentives innovation will decline, and the average purchase power will decrease.

Marxism has been tried and failed.

Perhaps the rich should be taxed differently, but the simplistic assertion (ending poverty four times over) is obviously false.

jake_Don Microsoft's ARM blunder: Why Windows RT was DOA

Let's see. To the businesses, MS has nothing substantially new or exciting to offer.

True, desktop usage will probably remain about the same (with a slight decline), but meanwhile, the mobile computing world is growing rapidly, with MS being largely out of the picture.

Desktop OSes will continue to sale, but they become day-by-day a very small fragment of the OSes out there. Win7 is a great OS, but I'm sure various alternatives, coming from the mobile world and leveraging their success there, will try to replace it.

I love Windows (7), use Visual Studio and other Microsoft tools daily, but this has nothing to do with the real changes that occur in the tech world.

MS bet wrong, and as occurs in the free market, they'll lose.

jake_Don Microsoft's ARM blunder: Why Windows RT was DOA

Businesses work on desktops and active directories. WinRT makes no sense on the desktop, and it offers no AD.

So MS has nothing to offer here, B2B wise.

They made a huge mistake, pretending that desktops and mobile devices are the same beast. And they're gonna pay for it, in sales and market value. At the end of 2013, they should be a even less relevant than today.
