Submission + - ownCloud 6 will have document editing (karlitschek.de)

oever writes: ownCloud is announcing an exciting new feature for ownCloud 6. It seems that it might grow into a Google Docs alternative. Today Frank Karlitschek blogged about ownCloud Documents, a new feature that lets multiple users work on one text document at the same time. The feature uses WebODF, a javascripts libary for editing ODF documents.

Comment Re:Hydrogen is indeed quite dangerous... (Score 3, Informative) 479

Most of the time, the hydrogen for fuel cells is stored in form of metal hydrides. I don't think that it gets explosively released, even in case of a crash. It's not a pressure tank. It needs to get seriously heated (150 degrees Celsius?) from the *inside* first before the tank starts venting it.

"QIp vIghro' pum" translates to "stupid cat falls" without a 'investment' and braving more than a decade of dust.

Actually, it translates to "fall cat stupid". "Stupid cat falls" would be "pum vIghro' QIp". (Perhaps on the Moon, it should have been "pumlI' vIghro' QIp", but I digress...)

First Experimental Evidence That Time Is an Emergent Quantum Phenomenon 530

KentuckyFC writes "One of the great challenges in physics is to unite the theories of quantum mechanics and general relativity. But all attempts to do this all run into the famous 'problem of time' — the resulting equations describe a static universe in which nothing ever happens. In 1983, theoreticians showed how this could be solved if time is an emergent phenomenon based on entanglement, the phenomenon in which two quantum particles share the same existence. An external, god-like observer always sees no difference between these particles compared to an external objective clock. But an observer who measures one of the pair — and so becomes entangled with it--can immediately see how it evolves differently from its partner. So from the outside the universe appears static and unchanging, while objects that are entangled within it experience the maelstrom of change. Now quantum physicists have performed the first experimental test of this idea by measuring the evolution of a pair of entangled photons in two different ways. An external god-like observer sees no difference while an observer who measures one particle and becomes entangled with it does see the change. In other words, the experiment shows how time is an emergent phenomenon based on entanglement, in which case the contradiction between quantum mechanics and general relativity seems to melt away."

I wonder if the base price includes PowerVM or a graphics card.

I wish I knew. The last Unix box I had was an Indy. Probably not the first thing, though - the Specifications page lists all of "PowerVM {Express|Standard|Enterprise} Edition" as "(optional)". According to the fine documentation, you can order "POWER GXT145 PCI Express Graphics" for your machine. If you want to run AIX on the box, I have no idea what the AIX level support is for this hardware. Forget CAD systems, though, this doesn't look like that kind of graphics hardware.

What is a "base price" for these machines, anyway? :)
