Submission + - Samba Team Releases Samba 4.0 (

dgharmon writes: As the culmination of ten years' work, the Samba Team has created the first compatible Free Software implementation of Microsoft’s Active Directory protocols. Familiar to all network administrators, the Active Directory protocols are the heart of modern directory service implementations. Samba 4.0 comprises an LDAP directory server, Heimdal Kerberos authentication server, a secure Dynamic DNS server, and implementations of all necessary remote procedure calls for Active Directory. Samba 4.0 provides everything needed to serve as an Active Directory Compatible Domain Controller for all versions of Microsoft Windows clients currently supported by Microsoft, including the recently released Windows 8.

The Samba 4.0 Active Directory Compatible Server provides support for features such as Group Policy, Roaming Profiles, Windows Administration tools and integrates with Microsoft Exchange and Free Software compatible services such as OpenChange.

The Samba 4.0 Active Directory Compatible Server can also be joined to an existing Microsoft Active Directory domain, and Microsoft Active Directory Domain Controllers can be joined to a Samba 4.0 Active Directory Compatible Server, showing true peer-to-peer interoperability of the Microsoft and Samba implementations of the Active Directory protocols.


Submission + - Huge Party at NASA Ames

SlaveLeia writes: Wired reminds us that there will be a huge party with hints of Burning Man and Maker Faire at NASA Ames Research center on Saturday April 12th. The event, which will be held in a huge hangar decorated with bizarre sculptures and neon lights, is meant to commemorate the first manned space flight by Yuri Gagarin. Stewart Brand, who founded the Global Business Network, Whole Earth Catalog, Long Now Foundation, and contributes to Wired Magazine will make some short remarks. Will Wright, creator of the SIMS, will give a longer talk. At the same time, here will be smaller events in other cities.

Submission + - RF Energy Breaks H2O Bonds in Saltwater Solution

Out of Round writes: While researching a means to cure his cancer, inventor John Kanzius serendipitously discovered that radiating saltwater with RF energy at a frequency 14GHz, results in the release of H2 and O at a significant rate. The article doesn't mention the amount of RF power used but there is a You Tube video showing the process in action with the resulting vigorous flame spewing out of the test tube powering a Stirling engine. The mechanism for this phenomenon is not understood but with sufficient conversion efficiencies, it could have wide-ranging implications for the future of this planet.

Submission + - Giant black holes power highest-energy cosmic rays

mcgrew (sm62704) writes: "New Scientist says

The finding, from a telescope array 10 times the size of Paris, solves a long-standing mystery about the origins of the most energetic cosmic rays that strike the Earth's atmosphere....

[T]he origins of the highest-energy particles, which travel within a whisker of the speed of light, have been puzzling. A single proton can have as much energy as a tennis ball served at 100 kilometres per hour.

Astronomers found it difficult to explain how particles are accelerated to such enormous speeds.
The article says these new findings herald "the beginning of cosmic ray astronomy"."

Submission + - normal man-with thin sheet of actual brain tissue

TasaDasa writes: WASHINGTON (Reuters ) — A man with an unusually tiny brain managed to live an entirely normal life despite his condition, caused by a fluid buildup in his skull, French researchers reported on Thursday. Scans of the 44-year-old man's brain showed that a huge fluid-filled chamber called a ventricle took up most of the room in his skull, leaving little more than a thin sheet of actual brain tissue.

Submission + - Inflatable space station/hotel by 2015

An anonymous reader writes: An experimental spacecraft designed to test the viability of a hotel in space has been successfully sent into orbit. Bigelow Aerospace hopes to build a full-scale space hotel, dubbed Nautilus, which will link a series of inflatable modules together like a string of sausages. Genesis II the inflatable and flexible core of the spacecraft is a 15 ft (4.5m) inflatable module designed to expand to a diameter of 8ft (2.4m). Later this year it plans to launch another module, Galaxy, described as a halfway house to a human-habitable space module. Mr Bigelow is offering a $50m prize to anyone who can design a craft capable of carrying five people to a height of 400km (250 miles) before 2010.

Submission + - NASA to use Metric System on Moon Mission

JustOK writes: With the first mission scheduled for 2020, NASA plans, among other things, to use "metric units for all operations on the lunar surface"
"NASA's lunar plan also encourages participation by other nations, as well as non-governmental organizations and commercial groups." NASA has nearly 60 space and Earth science projects currently, with about half having some type of international cooperation. North and South lunar poles are being looked at as locations for moon bases. Lunar stays of up to 180 days are being planned.
The project will see "A string of robot spacecraft will shoot for the Moon within the next two years, departing from Japan, China, India, as well as the United States."
According to a report via Yahoo! by staff, NASA has had informal discussions on using Internet protocols for lunar communications.
