Re: Differences from virtualisation?

That was certainly the explanation I heard from Red Hat this week - the CPU overhead for docker is less than 10% (typically about 5%, I think the figure was) and the memory overhead is much less too.

Plus, if there are multiple docker instances running and all looking at the same library then it'll use the library in the host rather than the docker image. If it's a different one on each instance, the instances will load their own.

Multi Jet Fusion: THAT's HP's promised 3D printer, not crazy 'leccy invention

Re: coming soon

"Tom's Hardware claims that "Those competitors are not so much the consumer-grade MakerBots of the world, but more like Stratasys; which is to say, this technology is aimed primarily at commercial applications." I'm eager to see more ceramic/metal/circuit/cellulose extrusion in the future so we can move beyond plastic, chocolate, and pizza printers."

I think I'd trust Stratasys more in this business than HP. The latter may have a long track record with printers, but Stratasys has the longer and better track record on RP machines and "3D Printing." They were, after all, one of the original RP companies, along with the likes of 3D Systems and EOS.

UK smart meters arrive in 2020. Hackers have ALREADY found a flaw

I wonder whether their "smart meters" will be smart enough to realize that there are PV "solar" panels on my roof and that the meter will get electricity flowing in the opposite direction when it's light and sunny?

Oh, and nobody with any sense would build a base-load gas fired power station, since gas fired stations were never, ever, ever, designed for running base-load. However, the fact that we have gas plants like the one that had a fire in Didcot proves that the people making the decisions have no sense.
