Posted by Soulskill on Saturday January 23, 2010 @11:32AM from the more-and-better dept.

ruphus13 writes "Nmap has a new release out, and it's a major one. It includes a GUI front-end called Zenmap, and, according to the post, 'Network admins will no doubt be excited to learn that Nmap is now ready to identify Snow Leopard systems, Android Linux smartphones, and Chumbies, among other OSes that Nmap can now identify. This release also brings an additional 31 Nmap Scripting Engine scripts, bringing the total collection up to 80 pre-written scripts for Nmap. The scripts include X11 access checks to see if X.org on a system allows remote access, a script to retrieve and print an SSL certificate, and a script designed to see whether a host is serving malware. Nmap also comes with netcat and Ndiff. Source code and binaries are available from the Nmap site, including RPMs for x86 and x86_64 systems, and binaries for Windows and Mac OS X. '"

Opera 10.5 Pre-Alpha Is Out, and It's Fast 274

Posted by kdawson on Tuesday December 22, 2009 @05:32PM from the fat-lady-has-not-sung dept.

sgunhouse writes to let us know that, following a leaked internal build over the weekend, Opera Software has now released their official 10.5 pre-alpha. There are no Linux versions yet. And an anonymous reader adds, "Opera's 10.5 pre-alpha includes the Carakan JavaScript Engine. Benchmarks now show that Opera is competitive with Chrome, beating it in Sunspider and other tests. Safari, Firefox, and IE are all behind. This is still pre-alpha, so further speed gains should be expected."

New Antifreeze Molecule Isolated In Alaskan Beetle 108

Posted by ScuttleMonkey on Monday December 21, 2009 @06:44PM from the cold-hard-science dept.

Arvisp writes with the news of a recently discovered antifreeze molecule in an Alaskan beetle that departs from most commonly identified natural antifreeze. "'The most exciting part of this discovery is that this molecule is a whole new kind of antifreeze that may work in a different location of the cell and in a different way,' said zoophysiologist Brian Barnes, director of the University of Alaska Fairbanks Institute of Arctic Biology and one of five scientists who participated in the Alaska Upis ceramboides beetle project. Just as ice crystals form over ice cream left too long in a freezer, ice crystals in an insect or other organism can draw so much water out of the organism's cells that those cells die. Antifreeze molecules function to keep small ice crystals small or to prevent ice crystals from forming at all. They may help freeze-tolerant organisms survive by preventing freezing from penetrating into cells, a lethal condition. Other insects use these molecules to resist freezing by supercooling when they lower their body temperature below the freezing point without becoming solid."

Red Hat Open Sources SPICE Desktop Virtualization 79

Posted by kdawson on Friday December 11, 2009 @10:34AM from the one-desktop-at-a-thyme dept.

laxl writes "Linux vendor Red Hat has open sourced the Simple Protocol for Independent Computing Environment (SPICE) virtual desktop protocol it acquired last year with Qumranet, which used SPICE for its own commercial desktop-virtualization product, called SolidIce. SPICE can be used to deploy virtual desktops from a server out to remote computers, such as desktop PCs and thin-client devices. It is similar to other rendering protocols used for remote desktop management such as Microsoft's Remote Desktop Protocol or Citrix's Independent Computing Architecture. SPICE supports rendering virtual instances of Windows XP and Windows 7, as well as Red Hat Enterprise Linux. According to Red Hat, SPICE has advantages over other protocols in that it can dynamically customize desktop instances to fit specific operating environments. According to the article, most of the SPICE code is available under the GNU GPLv2, though parts are also licensed under LGPL- and BSD-styled licenses."

heychris writes "You've gotta love the Chicago Tribune's story on Tesla Coil hobbyists from the first sentence. 'Under a starry Saturday sky behind a Lake Zurich warehouse, three men unload a small flamethrower, electric cabling, neon-tube "light sabers," about 80 pounds of chain mail and two 7-foot devices that look like monster-movie props.' So what does one do with 1.6 million volts and a Tesla coil or two? Play 110dB music, of course."

NASA Nebula, Cloud Computing In a Container 55

Posted by CmdrTaco on Wednesday December 02, 2009 @11:21AM from the you're-the-guys-thinking-stuff-up dept.

1sockchuck writes "NASA has built its Nebula cloud computing platform inside a data center container so it can add capacity quickly, bringing extra containers online in 120 days. Nebula will provide on-demand computing power for NASA researchers managing large data sets and image repositories. 'Nebula has been designed to automatically increase the computing power and storage available to science- and data-oriented web applications as demand rises,' explains NASA's Chris Kemp. NASA has created the project using open source components and will release Nebula back to the open source community. 'Hopefully we can provide a good example of a successful large-scale open source project in the government and pave the way for similar projects in other agencies,' the Nebula team writes on its blog."

Tapering Waveguide Captures a Rainbow 72

Posted by kdawson on Saturday November 28, 2009 @03:51PM from the you-fight-with-light-surely-that-is-forbidden dept.

SubComdTaco passes along news of researchers in the US who have trapped a rainbow in a tapering waveguide. The research is described (PDF) on the arXiv. "In 2007, Ortwin Hess of the University of Surrey in Guildford, UK, and colleagues proposed a technique to trap light inside a tapering waveguide [made of metamaterials]... The idea is that as the waveguide tapers, the components of the light are made to stop in turn at ever narrower points. That's because any given component of the light cannot pass through an opening that's smaller than its wavelength. This leads to a 'trapped rainbow.' ... Now Vera Smolyaninova of Towson University in Baltimore, Maryland, and colleagues have used a convex lens to create the tapered waveguide and trap a rainbow of light. They coated one side of a 4.5-mm-diameter lens with a gold film..., and laid the lens — gold-side down — on a flat glass slide which was also coated with film of gold. Viewed side-on, the space between the curved lens and the flat slide was a layer of air that narrowed to zero thickness where the lens touched the slide — essentially a tapered waveguide. When they shone a multi-wavelength laser beam at the... gilded waveguide, a trapped rainbow formed inside. This could be seen as a series of colored rings when the lens was viewed from above with a microscope: the visible light leaked through the thin gold film."

Opera 10.10 Released, Includes New "Unite" Tech 262

Posted by ScuttleMonkey on Monday November 23, 2009 @04:16PM from the but-does-it-live-in-the-cloud dept.

Opera 10.10 has been released, and with it their new "Unite" technology, which allows users to share content directly between all of their own devices. Unite wraps both web browser and web server into a single package in an attempt to change the way users think about their browser. "'We promised Opera Unite would reinvent the Web,' said Jon von Tetzchner, CEO, Opera. 'What we are really doing is reinventing how we as consumers interact with the Web. By giving our devices the ability to serve content, we become equal citizens on the Web. In an age where we have ceded control of our personal data to third-parties, Opera Unite gives us the freedom to choose how we will share the data that belongs to us.'"

Submission + - Air Force Officer Calls for Military Botnet (bbc.co.uk)

Submitted by GigsVT on Tuesday November 17, 2009 @01:04PM

GigsVT writes: A US Air Force officer has told the BBC that his country should create an offensive botnet to target any forces that launch a cyber-attack against it. "I recommend that we make our botnet — the botnet I propose — public. The whole world knows about it. That we exercise it on ranges that other countries can see electronically, that they know what we're doing and then they are going to be more likely to back off before doing an attack because they have to take this into account," ...he argues that if a computer owner has failed to use anti-virus software and install the latest security patches, that machine may be a legitimate military target.

Intel Allows Release of Full 4004 Chip-Set Details 124

Posted by timothy on Monday November 16, 2009 @04:31PM from the cool-move-from-the-valley dept.

mcpublic writes "When a small team of reverse engineers receives the blessing of a big corporate legal department, it is cause for celebration. For the 38th anniversary of Intel's groundbreaking 4004 microprocessor, the company is allowing us to release new details of their historic MCS-4 chip family announced on November 15, 1971. For the first time, the complete set of schematics and artwork for the 4001 ROM, 4002 RAM, 4003 I/O Expander, and 4004 Microprocessor is available to teachers, students, historians, and other non-commercial users. To their credit, the Intel Corporate Archives gave us access to the original 4004 schematics, along with the 4002, 4003, and 4004 mask proofs, but the rest of the schematics and the elusive 4001 masks were lost until just weeks ago when Lajos Kintli finished reverse-engineering the 4001 ROM from photomicrographs and improving the circuit-extraction software that helped him draw and verify the missing schematics. His interactive software can simulate an ensemble of 400x chips, and even lets you trace a wire or click on a transistor in the chip artwork window and see exactly where it is on the circuit diagram (and vice-versa)."
