Ubuntu 11.04 introduces Unity, Ubuntu’s new interface, which is simpler, easier to use and more beautiful than previous editions of Ubuntu. This is the culmination of two years’ design and engineering effort by Canonical and the Ubuntu community. Ubuntu 11.04 stands out from its competitors as a genuine free alternative to Windows, allowing users to personalize their PC with free and paid apps in a way that’s proven hugely popular in the smartphone and tablet market."

It is a bit hard to download the iso image. Several attempts to click the link failed. Looks like The download link was loaded with enthusiast users already."

New Evidence Presented For Ancient Fossils In Mars Rocks 91

azoblue passes along a story in the Washington Post, which begins: "NASA's Mars Meteorite Research Team reopened a 14-year-old controversy on extraterrestrial life last week, reaffirming and offering support for its widely challenged assertion that a 4-billion-year-old meteorite that landed thousands of years ago on Antarctica shows evidence of microscopic life on Mars. In addition to presenting research that they said disproved some of their critics, the scientists reported that additional Martian meteorites appear to house distinct and identifiable microbial fossils that point even more strongly to the existence of life. 'We feel more confident than ever that Mars probably once was, and maybe still is, home to life,' team leader David McKay said at a NASA-sponsored conference on astrobiology."

A version of the Legend of Mir server was leaked/stolen. It was the complete server program (I'm not sure if the source code was stolen too) and that allowed completely private servers to work with the existing client. These servers could then change the stats on items, change what mobs spawned where and create new mobs. I'm not sure how difficult it would have been or if it was possible to create new maps and graphics etc without other tools.

Let me add that I am very disappointed in Science - Since it really only started in the 1920's, it made huge strides by converting the occult philosophies of relativity and quantum mechanics into rigorous systems in its first few years of existence, and then petered out, having done noting of equal import since. Science is nearly a hundred years old now, and in the last sixty, about the best it can boast about is remaking the occult mysticism of the continental drift doctrine into properly falsifiable Plate Tectonics. Really, it's Tragic.

I would argue that while it is debatable when exactly science started it was before the 1920's. Newton was certainly important but I agree that he wasn't really a modern scientist. There was however plenty of science done before the 1920's much of classical mechanics and wave dynamics, rudimentary atomic theory and thermodynamics was all good science and done well before the 1920's.

The theories of relativity and quantum mechanics were never occult philosophies describing them as such really ignores the history of how they were discovered and formalised. They were both very much science from the start, falsifiable hypothesis created to explain gaps in current theories to explain experimental evidence. That were then confirmed by experiment before being widely accepted.

I don't know where you get the idea that nothing has been done in the last 60 years. For a start the formalism of QFT and into making predictions and its amazing agreement with experiment are within that time frame. The standard model including precision measurements of CP violation, most of QCD and neutrino physics (the discovery of their mass very recent) are all new. Cosmology and astrophysics have also made huge progress recently as has condensed matter and nano technology physics. These are all just examples from physics since I can name these off the top of my head but the other sciences have also been busy.

Breaking the Squid Barrier 126

Posted by timothy
from the calimari-for-the-5000 dept.
An anonymous reader writes "Dr. Steve O'Shea of Auckland, New Zealand is attempting to break the record for keeping deep sea squid alive in captivity, with the goal of being able to raise a giant squid one day. Right now, he's raising the broad squid, sepioteuthis australis, from egg masses found in seaweed. This is a lot harder than it sounds, because the squid he's studying grow rapidly and eat only live prey, making it hard for them to keep the squid from becoming prey themselves. If his research works out, you might one day be able to visit an aquarium and see giant squid."

Porsche's latest supercar will use the same 911 production platform available to consumers today, with a few race-ready features including front-wheel hybrid drive and an innovative flywheel system that stores kinetic energy from braking and then uses it to provide a 160 horsepower burst of speed. The setup is sure to offer an advantage when powering out of turns and passing by other racers."

Grateful Dead Percussionist Makes Music From Supernovas 57

At the "Cosmology At the Beach" conference earlier this month, Grammy-award winning percussionist Mickey Hart performed a composition inspired by the eruptions of supernovae. "Keith Jackson, a Berkeley Lab computer scientist who is also a musician, lent his talents to the project, starting with gathering data from astrophysicists like those at the Berkeley Lab’s Nearby Supernova Factory, which collects data from telescopes in space and on earth to quickly detect and analyze short-lived supernovas. 'If you think about it, it's all electromagnetic data — but with a very high frequency,' Jackson said of the raw data. "What we did is turn it into sound by slowing down the frequency and "stretching" it into an audio form. Both light and sound are all wave forms — just at different frequencies. Our goal was to turn the electromagnetic data into audio data while still preserving the science.'"

M.U.L.E. Is Back 110

jmp_nyc writes "The developers at Turborilla have remade the 1983 classic game M.U.L.E. The game is free, and has slightly updated graphics, but more or less the same gameplay as the original version. As with the original game, up to four players can play against each other (or fewer than four with AI players taking the other spots). Unlike the original version, the four players can play against each other online. For those of you not familiar with M.U.L.E., it was one of the earliest economic simulation games, revolving around the colonization of the fictitious planet Irata (Atari spelled backwards). I have fond memories of spending what seemed like days at a time playing the game, as it's quite addictive, with the gameplay seeming simpler than it turns out to be. I'm sure I'm not the only Slashdotter who had a nasty M.U.L.E. addiction back in the day and would like a dose of nostalgia every now and then."

I'm confused.

You have a telescope that receives light from a distant object. At first:

-you don't know what it is made of

-you don't know how far away it is

-and you don't know how fast its relative motion is

How can you use red shift to predict relative motion? A shift implies a motion, and you don't know where it is moving from.

How can you make any prediction about composition if you can't be sure of the shift?

How can you make and prediction about distance if you are making up numbers about the previous two?

I've got to read a book or two on cosmology sometime. I suspect there is a lot of 'splaining left out.

And I would expect the oldest galaxies to have the least amount of hydrogen left, having had stars burning it the longest.

It goes like this:
You use epctral analysis to determine what its made of by looking for known patterns in the spectrum of the light

You measure the redshift, to estimate the distance you either guess the absolute magnitude (which can often be done with gallaxies to at least give an upper limit) or you use hubbles law and assuming you have a good value of hubbles parameter you can convert red shift to distance. This is a bit circular and relies on you allready having found the distance of lots of objects without having to resort to this.

The redshift gives the relative motion and can be measured very acuratly and very easily.

You can tell the composition beofer you know the shift in fact you use the composition you get the shift.

While your not making up the numbers of the previous two it is worth pointing out that the distance measurement is not independent in some cases so you have to be very carefull the measurement of distance may be relying on your cosmological assumptions. Not all distance measurements are like this but the further back you go the harder it is to get a an independent measurement.

If you read a couple of books on cosmology most will cover these very basic principles any explaining left out will be in the larger more advanced books on cosmology.

Remember telescopes look back in time, these gallaxies are the ones that formed earliest.
