Moja maszynka z Q6600 już na ciężarowce FedEx w Georgii, ale niestety z pudla wyjdzie z Vista. Mniej więcej wiem jak na to zrobić dual boot z XP Pro, który jest w moim przypadku niezbędny. Mam Partition Magic, trochę instrukcji i coś tam jeszcze.

Dodatkowo będzie mi potrzebny jakiś Linux żeby Nokie N800 całkowicie odblokować. Co do Linuksa to mam mniej niż zero doświadczenia, wiec może koledzy i koleżanki mi poradzicie co i jak to na tym samym systemie zainstalować? Jakieś proste distro (Ubuntu? Debian?), ale żeby dwa inne OSy na tym też były. Da się to łatwo zrobić?

Czytam sobie artukul w Wyborczej gdzie kierownik centrum zarządzania siecią komputerową, Tomasz K, sie wypowiada mowiac, ze on czesto blokowal wymiane plikow miedzy studentami piratami.

Poznalem to nazwisko i to ten sam Tomek, zalozyciel swego czasu #1 w Polsce przez dlugie lata druzyny w SETI (to byl moj pierwszy zespol w 2001 roku)

Ogolnie sie chyba nie popisal choc mowil, ze ta siec trudno jest kontrolowac. Mial biedak jeszcze pecha, ze akurat zaczeli od Jego sieci... Ciekawe kto bedzie nastepny.

Moj 2x333MHz wynalazek sie nameczyl co prawda i narzekam, ale czy ktos kiedys widzial taka rozbieznosc?

Kupilem wczoraj za $50 - na taki odtwarzacz lata czekalem... 1GB z rozszerzeniem microSD, wyswietlacz, zewnetrzny mikrofon, polaczenie USB bez zbednych kabli, kompatybilnosc z audible.com no i dobrej jakosci radio FM! Wielkosc mnie wiecej porownywalna z oryginalnym Shuffle.

Moje najnowsze urzadzenie ma wbudowane Folding@Home, wiec "skladam" powolutku od wczoraj. Linuxa dodatkowego mozna zaladowac, wiec podejrzewam, ze SETI tez sie da liczyc.

Ciekawe jak sie bedzie porownywac z normalnym PC? W Folding przy tym podobno wszystko wymieka.

Sorry za zdjecie, ale pstryknalem swoim drugim 60 GB wynalazkiem, wiec jakosc cieniutka.

Temperatury podobne do naszych, byc moze jest woda, a sama planeta jest na orbicie bardzo bliskiej do czerwonego karla (14 razy blizej niz my do slonca), ktory jest duzo mniejszy, ciemniejszy i zimniejszy od slonca. Malo o tej planecie na razie wiadomo poza tym, ze jest stosunkowo blisko (20 i pol lat swietlnych) i poza Marsem, ktory spelnia podobne wymagania, to jest pierwsza planeta poza Ukladem Slonecznym, na ktorej mozna "zamieszkac". Widok dosc ladny, karzel z powierzchni wyglada na 20 razy wiekszego niz nasz ksiezyc. Prawdopodobnie, planeta nie kreci sie wokol swojej osi, czyli tylko jedna strona jest sloneczna. Grawitacja to 160% naszej.

I kto mi tu jeszcze powie, ze Star Trek albo Battlestar Galactica to science fiction? Przeciez to czysta nauka ze scenariuszem opartym na prawdziwych wydarzeniach ;-)

Planeta zostala odkryta przez 11 naukowcow z Genewy uzywajacych specjalnego teleskopu w La Silla, Chile.


Potentially Habitable Planet Found

By SETH BORENSTEIN, AP Science Writer


WASHINGTON - For the first time astronomers have discovered a planet outside our solar system that is potentially habitable, with Earth-like temperatures, a find researchers described Tuesday as a big step in the search for "life in the universe."

The planet is just the right size, might have water in liquid form, and in galactic terms is relatively nearby at 120 trillion miles away. But the star it closely orbits, known as a "red dwarf," is much smaller, dimmer and cooler than our sun.

There's still a lot that is unknown about the new planet, which could be deemed inhospitable to life once more is known about it. And it's worth noting that scientists' requirements for habitability count Mars in that category: a size relatively similar to Earth's with temperatures that would permit liquid water. However, this is the first outside our solar system that meets those standards.

"It's a significant step on the way to finding possible life in the universe," said University of Geneva astronomer Michel Mayor, one of 11 European scientists on the team that found the planet. "It's a nice discovery. We still have a lot of questions."

The results of the discovery have not been published but have been submitted to the journal Astronomy and Astrophysics.

Alan Boss, who works at the Carnegie Institution of Washington where a U.S. team of astronomers competed in the hunt for an Earth-like planet, called it "a major milestone in this business."

The planet was discovered by the European Southern Observatory's telescope in La Silla, Chile, which has a special instrument that splits light to find wobbles in different wave lengths. Those wobbles can reveal the existence of other worlds.

What they revealed is a planet circling the red dwarf star, Gliese 581. Red dwarfs are low-energy, tiny stars that give off dim red light and last longer than stars like our sun. Until a few years ago, astronomers didn't consider these stars as possible hosts of planets that might sustain life.

The discovery of the new planet, named 581 c, is sure to fuel studies of planets circling similar dim stars. About 80 percent of the stars near Earth are red dwarfs.

The new planet is about five times heavier than Earth. Its discoverers aren't certain if it is rocky like Earth or if its a frozen ice ball with liquid water on the surface. If it is rocky like Earth, which is what the prevailing theory proposes, it has a diameter about 1 1/2 times bigger than our planet. If it is an iceball, as Mayor suggests, it would be even bigger.

Based on theory, 581 c should have an atmosphere, but what's in that atmosphere is still a mystery and if it's too thick that could make the planet's surface temperature too hot, Mayor said.

However, the research team believes the average temperature to be somewhere between 32 and 104 degrees and that set off celebrations among astronomers.

Until now, all 220 planets astronomers have found outside our solar system have had the "Goldilocks problem." They've been too hot, too cold or just plain too big and gaseous, like uninhabitable Jupiter.

The new planet seems just right — or at least that's what scientists think.

"This could be very important," said NASA astrobiology expert Chris McKay, who was not part of the discovery team. "It doesn't mean there is life, but it means it's an Earth-like planet in terms of potential habitability."

Eventually astronomers will rack up discoveries of dozens, maybe even hundreds of planets considered habitable, the astronomers said. But this one — simply called "c" by its discoverers when they talk among themselves — will go down in cosmic history as No. 1.

Besides having the right temperature, the new planet is probably full of liquid water, hypothesizes Stephane Udry, the discovery team's lead author and another Geneva astronomer. But that is based on theory about how planets form, not on any evidence, he said.

"Liquid water is critical to life as we know it," co-author Xavier Delfosse of Grenoble University in France, said in a statement. "Because of its temperature and relative proximity, this planet will most probably be a very important target of the future space missions dedicated to the search for extraterrestrial life. On the treasure map of the Universe, one would be tempted to mark this planet with an X."

Other astronomers cautioned it's too early to tell whether there is water.

"You need more work to say it's got water or it doesn't have water," said retired NASA astronomer Steve Maran, press officer for the American Astronomical Society. "You wouldn't send a crew there assuming that when you get there, they'll have enough water to get back."

The new planet's star system is a mere 20.5 light years away, making Gliese 581 one of the 100 closest stars to Earth. It's so dim, you can't see it without a telescope, but it's somewhere in the constellation Libra, which is low in the southeastern sky during the midevening in the Northern Hemisphere.

"I expect there will be planets like Earth, but whether they have life is another question," said renowned astrophysicist Stephen Hawking in an interview with The Associated Press in Orlando. "We haven't been visited by little green men yet."

Before you book your extrastellar flight to 581 c, a few caveats about how alien that world probably is: Anyone sitting on the planet would get heavier quickly, and birthdays would add up fast since it orbits its star every 13 days.

Gravity is 1.6 times as strong as Earth's so a 150-pound person would feel like 240 pounds.

But oh, the view. The planet is 14 times closer to the star it orbits. Udry figures the red dwarf star would hang in the sky at a size 20 times larger than our moon. And it's likely, but still not known, that the planet doesn't rotate, so one side would always be sunlit and the other dark.

Distance is another problem. "We don't know how to get to those places in a human lifetime," Maran said.

Two teams of astronomers, one in Europe and one in the United States, have been racing to be the first to find a planet like 581 c outside the solar system.

The European team looked at 100 different stars using a tool called HARPS (High Accuracy Radial Velocity for Planetary Searcher) to find this one planet, said Xavier Bonfils of the Lisbon Observatory, one of the co-discoverers.

Much of the effort to find Earth-like planets has focused on stars like our sun with the challenge being to find a planet the right distance from the star it orbits. About 90 percent of the time, the European telescope focused its search more on sun-like stars, Udry said.

A few weeks before the European discovery earlier this month, a scientific paper in the journal Astrobiology theorized a few days that red dwarf stars were good candidates.

"Now we have the possibility to find many more," Bonfils said.

Chcialem pokazac moj nowy 60GB nabytek (JVC GZ-HD7U). Gdyby optyczna stabilizacja obrazu dzialala tak jak trzeba to bylaby w tym momencie najlepsza kamerka za te pieniadze. To cudo wyszlo oficjalnie w niedziele, a ja kupilem z pseudo-znizka juz w poniedzialek. 3CCD, optyka Fujinon, wszystkie wyjscia razem z HDMI, zbudowany w Japonii, a co najwazniejsze miesci 5 godzin HD w rozdzielczosci 1920x1080 (!). Koniec z miniDV nareszcie, nadchodzi czas zewnetrznych HD - tak z dwa terabajty trzeba bedzie znowu dostawic :-)

Dla skali stoi razem z butelka... wody mineralnej. W sam raz miesci sie w dloni.

Planeta podobna do Jowisza, 150 lat swietlnych od nas w konstelacji Pegasus:

Evidence of water has been detected for the first time in a planet outside our solar system, an astronomer said on Tuesday, a tantalizing find for scientists eager to know whether life exists beyond Earth.

Travis Barman, an astronomer at Lowell Observatory in Flagstaff, Arizona, said water vapor has been found in the atmosphere of a large, Jupiter-like gaseous planet located 150 light years from Earth in the constellation Pegasus. The planet is known as HD 209458b.

Other scientists reported in February that they were unable to find evidence of water in this planet's atmosphere, as well as another Jupiter-like planet.

"I'm very confident," Barman said in an interview. "It's definitely good news because water has been predicted to be present in the atmosphere of this planet and many of the other ones for some time."

Lowell Observatory, a privately owned astronomical research institution, announced the finding, which has been accepted for publication in the Astrophysical Journal. The research was backed by        NASA, it said.

The detection of the presence of water vapor was possible because this planet, from the vantage point of Earth, orbits directly in front of its star every 3-1/2 days, allowing crucial measurements to be made. It is what is known as a transiting planet.

Scientists searching for signs of life beyond Earth are keen to learn about the presence of water on other planets -- both in and beyond our solar system -- because water is thought to be fundamental to the existence of life.

Barman noted that a Jupiter-like gaseous planet such as this one, as opposed to a rocky one like Earth, is highly unlikely to harbor life, and said the finding about water vapor in its atmosphere does not answer one way or another questions about the existence of extraterrestrial life.

'PART OF PUZZLE'

The findings, he said, "are not adequate to really address a question as deep and profound as the existence of life elsewhere. We're not there yet."

"Certainly this is part of that puzzle -- understanding the distribution of water in other solar systems is important for understanding whether or not conditions for life are possible. The presence of water does not exclude the possibility of life, but it doesn't mean it's there, either," Barman added.

He said his findings do provide good reason to believe other planets beyond our solar system also have water vapor in their atmospheres.

The conclusions stemmed from an analysis of        Hubble Space Telescope measurements by Harvard University's Heather Knutson and new theoretical models developed by Barman, Lowell Observatory said.

Water is plentiful on Earth and has been found elsewhere in our solar system, for example in large deposits of ice at the north and south poles of Mars.

Planet HD 209458b also was the first planet outside the solar system found with an atmosphere and the first detected transiting planet. There are more than 200 known planets outside our solar system.
