Obama Toasts Tech With Industry Luminaries [PICS]

And a fine dinner it was at the Silicon Valley home of venture capitalist John Doerr, a partner with Kleiner Perkins Caufield & Byers. Take a look at the list of luminaries who were at the dinner with President Obama, discussing how government and technology businesses can work together to “win the future.”

• John Doerr, partner, Kleiner Perkins Caufield & Byers
• Carol Bartz, president and CEO, Yahoo!
• John Chambers, CEO and chairman, Cisco Systems
• Dick Costolo, CEO, Twitter
• Larry Ellison, co-founder and CEO, Oracle
• Reed Hastings, CEO, NetFlix
• John Hennessy, president, Stanford University
• Steve Jobs, chairman and CEO, Apple
• Art Levinson, chairman and former CEO, Genentech
• Eric Schmidt, chairman and CEO, Google
• Steve Westly, managing partner and founder, Westly Group
• Mark Zuckerberg, founder, president and CEO, Facebook

Why did they get together for this high-powered hang out? Here’s how a White House official described the dinner:

“The meeting is a part of our ongoing dialogue with the business community on how we can work together to win the future, strengthen our economy, support entrepreneurship, increasing our exports, and get the American people back to work. The President and the business leaders will discuss our shared goal of promoting American innovation, and discuss his commitment to new investments in research and development, education and clean energy.”

Here’s another shot with Zuckerberg and Obama schmoozing before dinner:

We’re still trying to identify a couple of the people in the photo at the top of the page — let us know if you have any clues. What do you think they’re toasting?

A Seismometer in Every Laptop

University researchers are behind an effort called the Quake-Catcher Network (QCN), a collaborative initiative for developing the world’s largest, low-cost seismic network. The group’s plan is to use sensors in and attached to Internet-connected computers to study earthquakes and their aftershocks.
Specifically, the group hopes volunteers will help them build a large distributed network of seismometers. The network would use the accelerometers that are now routinely available in laptops or USB-based accelerometers connected to desktop computers. Similar to SETI@Home and other distributed scientific research projects, users who want to help can download a small application to their computer. The software then collects information about the device’s motions obtained from the unit’s accelerometer.
If enough volunteers choose to participate, essentially every building and even every floor or part of a building (any place that has a laptop or desktop computer with a USB accelerator) could theoretically have a seismometer. This would give researchers very detailed measurements of quake motions on an unprecedentedly refined and small spatial scale.
Accelerometers in the Field
The QCN leverages the greatly increased availability of accelerometers already deployed in the field. These accelerometers are the ones installed in most of today’s laptops. They are used either as sudden-motion sensors or active protection systems whose purpose is to detect motions so that laptop hard disk drives (and the data on them) can be protected when the laptop experiences a sudden jolt. Seismologists can use these built-in accelerometers to gather details about the impact of earthquakes.
Unfortunately, the same level of convenience does not extend to desktops. Since desktop computers are not subject to the sudden drops and jostling that laptops undergo, most do not need and do not have built-in accelerometers. However, people with desktops who want to help out can use USB accelerometers that plug into their computers.

Data Collection Techniques
The QCN effort makes use of these accelerometers in the field, collecting information about the motions they detect. This is accomplished via software that users download to their laptops or desktops and the USB-attached accelerometer.

Naturally, there are some nuances that must be addressed for the data to be useful to the QCN researchers. For instance, they need to know the location of the device. With desktop systems, users typically provide the details once since the computer does not move. With laptops, users can either report their location or the researchers can estimate the location based on the IP address of the server used by the laptop to connect to the Internet. This gives a rough estimate of the laptop’s location. Researchers also hope to add a “Where Were You?” site, in which users would verify the location of the laptop when an earthquake occurred.

The data collected from the network of volunteers can substantially complement the information gathered by government and academic earthquake monitoring stations. Depending on the distribution and density of volunteer systems in the vicinity of an earthquake, researchers can get much finer-resolution details about the nature of a particular earthquake.

And since most large earthquakes have numerous aftershocks, QCN researchers can quickly ship USB accelerometers to a region after the fact, knowing that they will be able to get fine-scale details of these tremors. This is accomplished through a QCN effort called the Rapid Aftershock Mobilization Program (RAMP), which aims to rapidly deploy seismic sensors to any metropolitan region in the world hit by a major earthquake to understand how, when and where aftershocks happen.

HANDS ON: The Quietest (Powerful) Computer In The World [PICS]

Listen carefully to the sound your computer is making right now. Noisy? Most computers make noise, but we found one that’s tremendously powerful, yet it’s so quiet we couldn’t tell it was running.
I can’t stand constant, droning noise. It’s distracting, stressful, and it might even make you sick. One day I got fed up with the constant fan noise from my PC. I was on a mission: to find a powerful PC that would be completely quiet. Little did I realize that there’s an Internet subculture devoted to silent PCs, and one of its proponents is the Silent PC Review (SPCR).
The site has a special section of “SPCR Certified Silent PCs,” and the most silent computer those connoisseurs of quiet have ever found is a tower PC made by boutique computer assembler Puget Systems. The SPCR site calls Puget’s Serenity PC “the quietest computer system we have ever reviewed or even laid hands on, and probably quieter than any PC will ever be, short of one with no moving parts and zero electronic noise.” Concerned that Puget Systems is also one of the sponsors of that SPCR site, I vowed to test this quiet PC myself, and see if it lives up to its billing.
When I contacted Puget Systems in hopes of testing such a silent system, its CEO told me he’s just put together a smaller system he calls the Serenity Mini that’s even quieter than its full-sized brother. In an anechoic chamber, the Serenity PC measured a super-quiet 11dB, and Puget says this mini system is 1dB quieter, at 10dB. I had to check this out. A few days later, the Serenity Mini arrived, with its “mini-tower” case that’s by no means miniature, measuring about 17″ tall.
The object of this exercise was to find a PC with the fastest processors and finest components inside that can still scream without making a single sound. Of course, you can find other solid-state and fanless PCs with laptop processors inside that might match the quietude of these “silent PCs,” but you’d be missing out on all the power of Intel’s latest second-generation Core i7 tech embodied in its “Sandy Bridge” processing platform. So I tested a loaded PC with 8GB of RAM, a solid-state drive and the fastest Core i7 quad-core chip on board.
When I first fired up this Serenity Mini, I quickly realized that Silent PC Review wasn’t kidding. Even when I transformed our Midwest Test Facility into a completely silent environment by shutting down everything that makes even the slightest noise, including the refrigerator and the heating system, I still could not hear a peep emanating from of this PC.
How is this done? First of all, there’s that solid-state hard drive inside that makes no sound. There’s an almost equally quiet 1.5TB Caviar Green hard drive by Western Digital, a fanless PowerColor Radeon HD 5750 1GB graphics card, super-quiet Gelid Tranquillo CPU cooling , a Seasonic X-560 power supply that’s nearly silent, an Antec Mini P180 case, and then AcoustiPack foam padding lining the inside of the case. The result? State-of-the-art power with nearly complete silence.
Just how state-of-the-art is this power? Its quad-core Intel Core i7 2600K 3.4GHz chip is the fastest Sandy Bridge processor available at this writing, and it scored 6.86 points on the cross-platform Maxon Cinebench Benchmark 11.5. While no match for the two six-core Intel Xeon Westmere EP X5680 3.33GHz processors inside that Z800 workstation (which scored 16.22 points on that same Cinebench 11.5 benchmark), it held its own with its single quad-core chip.
By the way, Puget acknowledged the recent complaints of bugs in the “6 series” chipset associated with the Sandy Bridge processing platform, and says that all its PCs will be equipped with the modified chipset that Intel will be releasing soon.
Now you’re probably wondering, what’s the damage for such an unusually quiet and powerful machine? Puget is selling this one as tested for $2327, or if you’re a computer assembly expert and won’t need any help, you could put together this same group of components for a significantly lower price.
And now for the bottom line: How quiet is this machine compared with that 12-core workstation, an everyday laptop, and an exceptionally quiet PC? The difference is noticeable. To measure the difference between the sound output of each machine, I used a $.99 iPhone app called Decibel, with my iPhone positioned precisely 1 foot away from each machine. Granted, it’s not as completely scientific as the Silent PC Review’s measurements in an anechoic chamber, but for the purposes of comparison it will give you an idea of what I mean by silence:
