Comment Way to go, E! (Score 1) 114

I think this is goddamn just awesome. The only question I have is: why didn't someone think about this before?

I often find myself switching between CLI and GUI, either of which has usability advantages depending on the problem at hand. This one has a good chance of combining the some of advantages of both and come out as a solution outperforming either of the two traditional options. Nice job! So inspiring. Very creative! Way to go, E!

...they also seemed to have a rough spot in the past months. For months, there was no stable version available for ubuntu Precise, which is an LTS. Last month, they finally released 3.5.13.1, with support for Precise. I also had trouble accessing their web page and repos for many days in a row. Not exactly the kind of stability I would expect for my main DE.

By the way, KDE 3.5 was my first Linux experience. It was my DE of choice; it worked well and I liked the configurability. But I always found it butt ugly. Looked way old-fashioned and outdated compared to OSs/DEs. Tried a few different themes, but that only made it worse. I still stayed with it for its functionality. But I always found it totally unsexy.

It's because of what someone else explained further above: Higgs field is a quantum field, which fluctuates constantly. Particles spontaneously emerge and disappear all the time. Same thing is true for photons: even in a perfectly dark room, you have spontaneously photons appearing and disappearing. This leads to the so-called zero-point-field. Even when there are no "real" photons in a dark room, the electromagnetic field is not zero. It fluctuates around zero due to these so-called "virtual photons". Same is true for every quantum field. To generate a "real" Higgs particle you need 125 GeV. Virtual bosons come and go all the time (for free). Interaction with "massive" particles gives them their mass.

A photon bounces off mirrors because the electromagnetic field which describes the photon probability density is governed by Maxwell's equations. And according to those, and electromagnetic wave is reflected off a mirror (a perfect metal, for instance). Another way of looking at it is that photons interact with charges. When a photon approaches a metal, it stirs up the charges (electrons) inside the metal, which, in turn, interact with the photon (electromagnetic field) to change the photon's direction.

The way gravity affects the trajectory of photons is because (according to the theory of general relativity) mass distorts space-time itself. In this picture, you could think that the photon flies "straight" in a "bent" space-time.

MIT's 'Artificial Leaf' Makes Fuel From Sunlight 158

New submitter nfn writes "MIT has published a new paper (abstract), along with a video of a working prototype, of what they're describing as an 'Artificial Leaf' that separates water into oxygen and hydrogen using cheap, non-exotic materials. 'The artificial leaf — a silicon solar cell with different catalytic materials bonded onto its two sides — needs no external wires or control circuits to operate. Simply placed in a container of water and exposed to sunlight, it quickly begins to generate streams of bubbles: oxygen bubbles from one side and hydrogen bubbles from the other. If placed in a container that has a barrier to separate the two sides, the two streams of bubbles can be collected and stored, and used later to deliver power: for example, by feeding them into a fuel cell that combines them once again into water while delivering an electric current.' No word on the arrival of 'Artificial Salads,' or when any of their other alchemy projects will bear artificial fruit."

Totally agree. I gave up on Amarok, too. It's crazy how it's bloated with all these UI features I never use. I am using bare VLC now. It's not pretty and quite barebones. The backend is a dream, plays everything. Of course, it's totally lacking DE integration, and for my taste it's a bit too barebones, but what can I do. Surprisingly, there are not too many decent linux audio players around :(

This is what I have been waiting for. After my initial excitement about (k)ubuntu release updates to get all the hardware running and supported, I am now at a state where everything is fine. The ongoing new 6-month releases are more of an annoyance than a great feature. Having to upgrade completely every 6 months just to get access to the latest software releases does not seem like a worth while effort. Sure, you can say that's what the LTS releases are for. But while the LTS releases do enjoy long-term support for security-relevant updates, they do not get a lot of software updates. So if you favorite application gets a major update after the LTS release you are out of luck. (Of course, you can fiddle something together on your own, but that's not really a low-maintenance solution.) Also, from my experience the LTS do not have less bugs than regular releases.

So if they can make rolling releases working with a high level of quality and testing, this would be really awesome from my point of view.
