Greenpeace Lambastes Apple, Amazon, Microsoft for Creating Foul Clouds
Behind every cloud there supposedly is a silver lining, but a new report from Greenpeace, titled "How Clean Is Your Cloud?" may mean stormy weather for Apple, Amazon and Microsoft. The three tech giants use "dirty" energy to power their data centers, Greenpeace said. It looked at 14 of the largest tech companies' data centers and offered assessments of how much power they required, as well as what type of energy they used.
Droid RAZR and Droid RAZR MAXX software updates finally ready to roll out
Being a Droid RAZR or Droid RAZR MAXX owner has certainly had its ups and downs for the past little while. A bunch of false starts for software updates have occurred, but now it looks like Motorola and Verizon have managed to get things squared away for the better.
If you check out the Verizon support pages you'll find information for the 6.12.181 software update readily available for viewing, which means the actual updates could roll out pretty much anytime now.
No, it's not Ice Cream Sandwich, but we're sure you'll agree some updates are better than no updates at all. The change log is the same for both devices, so jump on past the break to get a detailed list

After 50 years, family moves from home for UDOT project ...
Posted on: 5:55 pm, April 16, 2012, by Aaron Vaughn, updated on: 06:36pm, April 16, 2012
WEST VALLEY CITY ? The new freeway that will cut through Salt Lake Valley?s west side is causing 100 more homes to be torn down to make way for construction. One family talked with FOX13 saying after decades raising their family, they are crushed learning they have to leave their home behind.To complete the Mountain View Corridor Project, Utah Department of Transportation says that 100 houses need to come down between 5800 West between 3500 and 4700 South.
The home owner along the proposed demolition site, Max Williams, says after living at his current house on Masters Way for 50 years, he does not know where else to go and does not want to leave with all his family?s memories tied to his home and neighborhood.
?My son built the cabinets, we put these big cabinets in, put tile all around it and fixed it up in here ? paper and painted it,? Max points out walking through his house slated for demolition.
Max Williams says he has worked on the home for many years to make it comfortable for him and his wife as they age. The house and the neighborhood is where they expected to live out their life.
?I was a bishop here for six-and-a-half years and got to love the people ? you get close to them. I?ve performed 32 marriages. A lot of those kids come back and they call us grandpa and grandma. And those things you?ll never forget,? says Williams.
Williams says he does not know where he will end up. At 82 years old, he is heartbroken, seeing some of his neighbors? homes already bought and boarded up by the state.
?We?ve got to get out whether we like it or not,? says Williams.
UDOT says they are paying each property owner the ?fair market price? as well as relocation expenses.
?What we?ll actually do is meet with each property owner, we?ll appraise the property pay fair market value as well as relocation expenses,? says UDOT project manager Teri Newell.
Williams worries about what fair market value for a home that is paid off and whether that amount will buy him another home given the current economic climate.
?We?ve raised our family. We know everybody in the neighborhood ? everybody around us. We?ve made friends with everybody. Now, you?ve got to move and you know when you get our age you can?t do things like that,? says Williams.
All of the home owners in this area are gearing up for a public meeting with UDOT on May 2 at Hunter High School, and at that time they say they may finally know what it means to get ?fair market value? for their homes.

Love in Jiangnan ? Blog Archive ? Microsoft Registry Cleaner ? Is ...
Computers are an important component of daily life. climate it is employed for school, company or just fun, nearly everybody nowadays has or understands how to make use of a computer. The vast majority of people today use house windows centered working products as nicely as the newest newest working technique to arrive from house windows is house windows Vista.
Keeping your personal computer fresh and operating smooth is the most beneficial method to improve efficiency and reduce the aggravation of obtaining a slow personal computer while you are functioning on an necessary task. among the most excellent methods to maintain your personal computer operating good is by cleanup the registry using a house windows Vista Registry cleaner.
Vista certified?
Many with the registry cleaners, even some huge title ones, are nonetheless not however prepared for Vista yet. So, be cautious when deciding on a registry cleaner to keep away from these when you have house windows Vista as your working system.
A beneficial registry cleaner has the capability to fresh the registry in purchase to obtain your computer?s rate up rate up and have it operate smoother with tiny to no errors. Registry cleaners also remove all those pesky spyware data files that hog a vast majority of your system?s sources and steal data out of your computer. The house windows Vista working technique is pretty unique in the earlier edition so it is necessary to make use of a genuine Vista registry cleaner.
Vista licensed indicates it may be provided Microsoft?s seal of approval, but while you believe about it, this really is not just a genuinely huge deal. If a reputable corporation feels its cleaner is prepared to cope with Vista that is beneficial sufficient for me. What microsof company thinks and why they believe it is secondary.
Registry optimization
Using the registry cleaner is pretty simple, fairly very much as straightforward as opening the plan and hitting a key to operate it. after it runs, it does all of the operate by itself, examining for issues and repairing them. the most beneficial registry cleaners also compress, or optimize the info too and this really is exactly where a vast majority with the rate enhance arrives from.
It keeps the registry as very much as day and removes all of the unnecessary and outdated data files not employed by your personal computer anymore. New to Vista registry cleaners, it also can cope with viruses and trojans as well, which not just slow right down your personal computer but are also pretty dangerous to it as well.
Newer working systems
Technology has progressed as nicely as the use use with the personal computer has heightened drastically. With all of the items you can do, like listen to music, view videos, surf the net, compose forms and more, you require a great deal more sources to become capable to hold out all this efficiently.
Cleaning the registry all this efficiently.
Cleaning the registry over a frequent foundation enables you to become capable to hold out all all of the without having slowing right down your computer. this really is since it doesn?t must operate as tough to operate all of those things. We reside in an age exactly where we are employed to obtaining items ideal now and pretty quickly also it becomes frustrating when we don?t have this luxury.
So cleanup the registry is among the most excellent methods to become certain you?re as very much as rate when functioning using a house windows working system, specially among the newer kinds like XP and Vista. Also if making use of Vista be sure the registry cleaner is Vista prepared or Vista compatible. However, whether or not or not microsof company has in fact licensed the cleaner for Vista it is not that important.

Researchers develop graphene supercapacitor holding promise for portable electronics
Researchers develop graphene supercapacitor holding promise for portable electronics
Friday, March 16, 2012Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially higher amounts of charges. They have garnered attention as energy storage devices as they charge and discharge faster than batteries, yet they are still limited by low energy densities, only a fraction of the energy density of batteries. An EC that combines the power performance of capacitors with the high energy density of batteries would represent a significant advance in energy storage technology. This requires new electrodes that not only maintain high conductivity but also provide higher and more accessible surface area than conventional ECs that use activated carbon electrodes.
Now researchers at UCLA have used a standard LightScribe DVD optical drive to produce such electrodes. The electrodes are composed of an expanded network of graphene ? a one-atom-thick layer of graphitic carbon ? that shows excellent mechanical and electrical properties as well as exceptionally high surface area.
UCLA researchers from the Department of Chemistry and Biochemistry, the Department of Materials Science and Engineering, and the California NanoSystems Institute demonstrate high-performance graphene-based electrochemical capacitors that maintain excellent electrochemical attributes under high mechanical stress. The paper is published in the journal Science.
The process is based on coating a DVD disc with a film of graphite oxide that is then laser treated inside a LightScribe DVD drive to produce graphene electrodes. Typically, the performance of energy storage devices is evaluated by two main figures, the energy density and power density. Suppose we are using the device to run an electric car ? the energy density tells us how far the car can go a single charge whereas the power density tells us how fast the car can go. Here, devices made with Laser Scribed Graphene (LSG) electrodes exhibit ultrahigh energy density values in different electrolytes while maintaining the high power density and excellent cycle stability of ECs. Moreover, these ECs maintain excellent electrochemical attributes under high mechanical stress and thus hold promise for high power, flexible electronics.
"Our study demonstrates that our new graphene-based supercapacitors store as much charge as conventional batteries, but can be charged and discharged a hundred to a thousand times faster," said Richard B. Kaner, professor of chemistry & materials science and engineering.
"Here, we present a strategy for the production of high-performance graphene-based ECs through a simple all solid-state approach that avoids the restacking of graphene sheets," said Maher F. El-Kady, the lead author of the study and a graduate student in Kaner's lab.
The research team has fabricated LSG electrodes that do not have the problems of activated carbon electrodes that have so far limited the performance of commercial ECs. First, The LightScribe laser causes the simultaneous reduction and exfoliation of graphite oxide and produces an open network of LSG with substantially higher and more accessible surface area. This results in a sizable charge storage capacity for the LSG supercapacitors. The open network structure of the electrodes helps minimize the diffusion path of electrolyte ions, which is crucial for charging the device. This can be accounted for by the easily accessible flat graphene sheets, whereas most of the surface area of activated carbon resides in very small pores that limit the diffusion of ions. This means that LSG supercapacitors have the ability to deliver ultrahigh power in a short period of time whereas activated carbon cannot.
Additionally, LSG electrodes are mechanically robust and show high conductivity (>1700 S/m) compared to activated carbons (10-100 S/m). This means that LSG electrodes can be directly used as supercapacitor electrodes without the need for binders or current collectors as is the case for conventional activated carbon ECs. Furthermore, these properties allow LSG to act as both the active material and current collector in the EC. The combination of both functions in a single layer leads to a simplified architecture and makes LSG supercapacitors cost-effective devices.
Commercially available ECs consist of a separator sandwiched between two electrodes with liquid electrolyte that is either spirally wound and packaged into a cylindrical container or stacked into a button cell. Unfortunately, these device architectures not only suffer from possible harmful leakage of electrolytes, but their design makes it difficult to use them for practical flexible electronics.
The research team replaced the liquid electrolyte with a polymer gelled electrolyte that also acts as a separator, further reducing the device thickness and weight and simplifying the fabrication process as it does not require special packaging materials.
In order to evaluate under real conditions the potential of this all solid-state LSG-EC for flexible storage, the research team placed a device under constant mechanical stress to analyze its performance. Interestingly enough, this had almost no effect on the performance of the device.
"We attribute the high performance and durability to the high mechanical flexibility of the electrodes along with the interpenetrating network structure between the LSG electrodes and the gelled electrolyte," explains Kaner. "The electrolyte solidifies during the device assembly and acts like glue that holds the device components together."
The method improves the mechanical integrity and increases the life cycle of the device even when tested under extreme conditions.
Since this remarkable performance has yet to be realized in commercial devices, these LSG supercapacitors could lead the way to ideal energy storage systems for next generation flexible, portable electronics.
