Top 11 reasons to use Google Apps

By offering low upfront costs, reduced overall risk, instant global reach and access to enterprise-level software solutions, Google Apps provides a compelling opportunity for every organization. Those who capitalize on it will reap significant immediate benefits.

I found the following reasons for why we must use google apps??

1.Eliminate email hassles instantly. No more outages, lost mail, spamming, phishing, viruses, security breaches.

2.Reduce costs. Eliminate the hardware, software, maintenance, upgrades, and services associated with your current environment.

3.Enable collaboration for everyone, from anywhere. Access and collaborate on all your documents and spreadsheets from anywhere in the world via a web browser.

4.Get everyone on the same page. Bring all your key information together in one central, easy-to-use, searchable location.

5.Reduce IT overload. Google handles all technical aspects, freeing up your team to focus on other projects, and allowing you to reduce your online communication and collaboration costs to one low monthly fee.

6.Instantly increase the productivity, knowledge, teamwork, and communication capabilities. Provide instantly accessible tools, including Web-based business class email, online document management, online calendars, blogs, wikis, etc. to your business and your team.

7.Make partnering and out-sourcing more efficient. Create a platform that can seamlessly support virtual ad-hoc teams (without the intervention of an “administrator”), thereby quickly reducing your costs.

8.Increase your peace of mind. With Google’s hosted, fast, safe, and secure file storage, you never have to worry about losing critical business information. You also never have to worry about scalability – Google apps will support any number of users who can be added at any time.

9.Get automatic versioning. Any change to any information in a Google document or spreadsheet creates a new version of the information. Even if a document or spreadsheet is being authored by many users simultaneously, none of the information will ever get lost. If any change is unacceptable, the contents of it can be quickly rolled back to any of its previous states with a couple of clicks.

10.Take advantage of continuous improvement. All Google Apps updates are immediately distributed to all customers. This means that you always have the latest and greatest features immediately available for use in your organization – without doing a thing.

11.New hires are already using this technology. People entering the workforce today have lived and breathed the web since they were in high school. If you don’t provide company endorsed solutions, they will end up using tools that are available on the open Internet until you do.

Skyray 48 Takes Flight

Friday, September 21, 2007

Years of research, design, construction, wind tunnel and ground tests coalesced into this one moment of time.

Radios crackled. "Tower, Skyray 48 in position, lakebed runway 23, request clearance for takeoff..."

"Skyray 48 roger, main base winds 220 at 6, report airborne, lakebed 23..."


"Five, four, three, two, one, brakes..."

Quickly, the manta ray-shaped aircraft rolled down the dry lakebed runway trailing a plume of dust as it picked up speed, its three small jet engines whining.

With an excitement that only comes with an aircraft's first flight, the triangular red, white and blue X-48B leapt into the air, obviously wanting to fly.

"Skyray 48's airborne," Boeing pilot Norm Howell called, matter-of-factly. And with that, years of toil blossomed into the sweet fruit of success on July 20, 2007 at NASA's Dryden Flight Research Center on Edwards AFB, Calif.

One of the latest cutting-edge experimental aircraft, or X-Planes, the X-48B BWB is a collaborative effort of the Boeing Co., NASA's Fundamental Aeronautics Program, and the Air Force Research Laboratory. The 21-foot wingspan, 500-pound, remotely piloted plane is designed to demonstrate the viability of the blended wing shape. And demonstrate it has.

After completion of six flights, the X-48B team began a four-week maintenance and modification period during which removable leading edges with extended slats are being replaced with slatless leading edges in order to mimic a slats-retracted configuration. The change requires a software update to the flight control software. In addition, the team is removing and replacing all of the aircraft's flight control actuators for maintenance purposes.

NASA is interested in the potential benefits of the aircraft - increased volume for carrying capacity, efficient aerodynamics for reduced fuel burn, and, possibly, significant reductions in noise due to propulsion integration options. In these initial flights, the principal focus is to validate prior research on the aerodynamic performance and controllability of the shape, including comparisons of flight test data with the extensive database gathered in the wind tunnels at NASA's Langley Research Center in Virginia.

The Subsonic Fixed-Wing Project, part of NASA's Fundamental Aeronautics Program, has long supported the development of the blended wing body concept. It has participated in numerous collaborations with Boeing, as well as several wind tunnel tests for different speed regimes. The team is focused on researching the low-speed characteristics of the design and expanding its flight envelope beyond the limits of current capabilities.

In addition to hosting the X-48B flight test and research activities, NASA Dryden is providing engineering and technical support -- expertise garnered from years of operating cutting-edge air vehicles. NASA assists with the hardware and software validation and verification process, the integration and testing of the aircraft systems, and the pilot's ground control station. NASA's range group provides critical telemetry and command and control communications during the flight, while the flight operations group provides a T-34 chase aircraft and essential flight scheduling. Photo and video support complete the effort.

The composite-skinned, 8.5 percent scale vehicle can to fly up to 10,000 feet and 120 knots in its low-speed configuration. The aircraft is flown remotely from a ground control station by a pilot using conventional aircraft controls and instrumentation, while looking at a monitor fed by a forward-looking camera on the aircraft.

Up to 25 flights are planned to gather data in these low-speed flight regimes. Then, the X-48B may be used to test the aircraft's low-noise and handling characteristics at transonic speeds.

Two X-48B research vehicles were built by Cranfield Aerospace Ltd., in England, in accordance with Boeing specifications. The vehicle that flew on July 20, known as Ship 2, was also used for ground and taxi testing. Ship 1, a duplicate, was used for the wind tunnel tests. Ship 1 is available for use as a backup during the flight test program.

So far, so good as the Skyray 48 team works through the late summer heat of the Mojave Desert as they continue blazing a trail with this futuristic aircraft design.

Intel open-source project to make Linux better.

Power management in Linux has been difficult to do. On Sept. 20, Intel announced the launch of an open-source community project,, which is designed to meet the demands for increased energy efficiency from data center servers to personal mobile devices.

was unveiled at IDF (Intel Developer Forum) in San Francisco by Renee James, corporate vice president and general manager of Intel's software and solutions group. The initiative brings together the community of Linux developers, ISVs and users to facilitate technology development, deployment, and tuning and sharing of information around Linux power management.

Linux's core developers agree that there is a pressing need for making Linux greener. At the Linux Foundation Collaboration Summit held at the Googleplex in June, leading Linux kernel programmer Andrew Morton said that "power management is no longer on or off." The problem, as always, the developers agreed, is that "Linux needs specifications for devices."

Jesse Barnes, a Linux developer from Intel, added that while Intel has been putting resources into power management, "We don't have enough, and we need other vendors to step up."

James Bottomley, vice president and chief technology officer of Steeleye Technology, a high-availability Linux vendor, said: "We're getting everyone to look at power management strategies." He feels that while power management "will never be perfect, at least we will have the instrumentation and a lot of knobs to twiddle."

Much of the concern for improved power management comes not so much from an interest in green computing as from vendors wanting to use Linux in their mobile devices. Greg Kroah-Hartman, a SUSE Linux developer added: "Mobile is asking for power management. I think the servers want it too, but they don't know it."

Theodore 'Ted' T'so, an IBM Linux developer, said: "A lot of the low-hanging fruit has been plucked on the kernel side" when it comes to power management. For example, many power management problems can be solved by improving Linux ACPI (Advanced Configuration and Power Interface) support, because most of the power control is currently hidden away in devices' proprietary firmware, where Linux developers can't get to it.

Now, with LessWatts, Intel is seeking to open up power management from large data centers, where server power consumption imposes limits on a center's growth and has significant financial and environmental costs to mobile users who are constrained by power consumption limits, as battery space is continually squeezed with the overall reduction in size of mobile devices.

"We created to accelerate technology development and simplify information sharing for effective power management across a broad spectrum of devices and industry segments that are utilizing Linux," said James. "A focused initiative that aggregates the disparate efforts into a holistic system and builds on our existing efforts with the industry in the Climate Savers Computing Initiative will serve as a strong catalyst to get energy-efficient solutions into the market segment faster, thereby benefiting the customers who purchase Intel-based products."

The initiative encompasses several key projects including Linux kernel enhancements (such as the Linux 2.6.21 "tickless idle" feature that takes better advantage of power saving hardware technologies), the PowerTOP tool that helps tune Linux applications to be power aware and the Linux Battery Life Toolkit to measure and instrument the impact of Linux code changes on power savings.

Additionally, provides Linux support for hardware power saving features being implemented in current and upcoming Intel platforms.

Intel is not making this move on its own. Other vendors have joined in the LessWatts initiative. "Community contributions are a fundamental part of Oracle's long-standing commitment to Linux and our collaboration with Intel in projects such as is another proof point," said Wim Coekaerts, Oracle's vice president of Linux engineering.

" can help customers reduce data center power consumption and make use of the latest hardware technologies, while further advancing the development, adoption and deployment of enterprise Linux solutions."

The leading corporate Linux vendors are also on board. "In response to customer demand for power savings across their entire IT environment, we've implemented significant features in Red Hat Enterprise Linux 5 that allow our customers to minimize their carbon footprint," said Paul Cormier, executive vice president of engineering at Red Hat, in a statement. Red Hat continues to work closely with Intel to provide customers with ecologically sensitive solutions, and we look forward to actively contributing to the project."

Jeff Jaffe, Novell executive vice president and chief technology officer, said: "Novell is working hard to be eco-friendly and customer-friendly at the same time by providing better power management technologies as part of SUSE Linux Enterprise. We are committed to helping drive the technology forward as part of and providing value to our customers by incorporating that technology into upcoming SUSE Linux Enterprise releases."
