Submission + - Gravitational Waves May Have Been Spotted (sciencemag.org)

synaptic writes: There is increasing excitement over the possibility that the LIGO instrument has detected gravitational waves. This is more than just rumor as the respected journal Nature will highlight the research in the February 11th edition. If this is true, the scientists involved will receive the Nobel Prize in Physics and the discovery may open new doors for mankind.

Submission + - Email stokes rumor that gravitational waves have been spotted (sciencemag.org)

sciencehabit writes: t's just a rumor, but if specificity is any measure of credibility, it might just be right. For weeks, gossip has spread around the Internet that researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) have spotted gravitational waves—ripples in space itself set off by violent astrophysical events. In particular, rumor has it that LIGO physicists have seen two black holes spiraling into each other and merging. But now, an email message that ended up on Twitter adds some specific numbers to those rumors. The author says he got the details from people who have seen the manuscript of the LIGO paper that will describe the discovery.

Submission + - Silver nanoparticle looks and behaves like Gold (phys.org)

An anonymous reader writes: 'In an act of "nano-alchemy," scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and on the inside, its chemical structure and properties also closely mimic those of its gold counterpart. The work shows that it may be possible to create silver nanoparticles that look and behave like gold despite underlying differences between the two elements, and could lead to creating similar analogues between other pairs of elements'

Wireless communications may become more interesting in the future thanks to this pioneering research: http://www.nature.com/articles...

See also the theoretical paper: http://journals.aps.org/prl/ab... (http://arxiv.org/pdf/math-ph/0703059.pdf)

It's not clear what the implications are for signal loss or if this is more of an illusion akin to beam steering.

Submission + - Need advice on Enterprise Architect position

dave562 writes: I could use some advice from the community. I have almost 20 years of IT experience, 5 of it with the company I am currently working for. In my current position, the infrastructure and applications that I am responsible for account for nearly 80% of the entire IT infrastructure of the company. In broad strokes our footprint is roughly 60 physical hosts that run close to 1500 VMs and a SAN that hosts almost 4PB of data. The organization is a moderate sized (~3000 employees), publicly traded company with a nearly $1 billion market value (recent fluctuations not withstanding).

I have been involved in a constant struggle with the core IT group over how to best run the operations. They are a traditional, internal facing IT shop. They have stumbled through a private cloud initiative that is only about 30% realized. I have had to drag them kicking and screaming into the world of automated provisioning, IaaS, application performance monitoring, and all of the other IT "must haves" that a reasonable person would expect from a company of our size. All the while, I have never had full access to the infrastructure. I do not have access to the storage. I do not have access to the virtualization layer. I do not have Domain Admin rights. I cannot see the network.

The entire organization has been ham strung by an "enterprise architect" who relies on consultants to get the job done, but does not have the capability to properly scope the projects. This has resulted in failure after failure and a broken trail of partially implemented projects. (VMware without SRM enabled. EMC storage hardware without automated tiering enabled. Numerous proof of concept systems that never make it into production because they were not scoped properly.)

After 5 years of succeeding in the face of all of these challenges, the organization has offered me the Enterprise Architect position. However they do not think that the position should have full access to the environment. It is an "architecture" position and not a "sysadmin" position is how they explained it to me. That seems insane. It is like asking someone to draw a map, without being able to actually visit the place that needs to be mapped.

For those of you in the community who have similar positions, what is your experience? Do you have unfettered access to the environment? Are purely architectural / advisory roles the norm at this level?

Submission + - Learn FPGAs with a $25 board and Open Source Tools (hackaday.com)

An anonymous reader writes: Hackaday has a 3 part tutorial with videos of using open source tools with a cheap ($25) FPGA board. The board isn't very powerful, but this could be the "gateway drug" to FPGAs for people who don't want to spend hundreds of dollars and install 100s of megabytes of software and license keys just to get their feet wet. The videos are particularly good--like watching them over their shoulder. As far as I know, this is the only totally open source FPGA toolchain out there.

You set some good deadlines but humanity has an opportunity to transcend these limits.


Type I
"Technological level close to the level presently attained on earth, with energy consumption at 4×1019 erg/sec (4 × 1012 watts)."[1] Guillermo A. Lemarchand stated this as "A level near contemporary terrestrial civilization with an energy capability equivalent to the solar insolation on Earth, between 1016 and 1017 watts."[2]

Type II
"A civilization capable of harnessing the energy radiated by its own star (for example, the stage of successful construction of a Dyson sphere), "with energy consumption at 4×1033 erg/sec."[1] Lemarchand stated this as "A civilization capable of utilizing and channeling the entire radiation output of its star. The energy utilization would then be comparable to the luminosity of our Sun, about 4×1033 erg/sec (4×1026 watts)."[2]

Type III
"A civilization in possession of energy on the scale of its own galaxy, with energy consumption at 4×1044 erg/sec."[1] Lemarchand stated this as "A civilization with access to the power comparable to the luminosity of the entire Milky Way galaxy, about 4×1044 erg/sec (4×1037 watts)."[2]

Comment Patriot Act Extension and the Autopen (Score 1) 237

Another rub on the Patriot Act, or rather the Patriot Act extension, is that it was not signed by the President. The extension bill was the first bill ever signed into law by the "autopen".

Article I, Section 7 - Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States; If he approve he shall sign it, but if not he shall return it, with his Objections to that House in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it. [...]

So it says "he shall sign it", not a robot. Is it law?
