Google Gives Away Google Voice

 

Google() explained, “We’ve heard college students in particular really appreciate getting their voicemail sent to their e-mail, sending free text messages and reading voicemail transcriptions rather than listening to messages (especially handy while in class).”

HTC EVO 4G

Sprint and HTC launch the first 4G handset in America -- and its got Android onboard.

 

As a mobile platform, the EVO 4G's Android foundation is still an infant -- well, okay, perhaps it's a tweener -- but in its two-odd years in the public spotlight, the list of truly revolutionary devices to use it has been a significant one: the G1 for being the first to market.

Hp Palm

HP: 'We're doubling down on webOS,' Palm: 'That was the whole point'

 

HP has just announced that it's acquiring Palm to the tune of $1.2 billion, which works out to $5.70 per share of Palm common stock. The deal is planned to close by July 31, which marks the end of HP's third fiscal quarter of the year.

Iphone OS 4

With over 100 new features, the free iOS 4 Software Update lets you do some amazing things

 

Now you can run your favorite third-party apps — and switch between them instantly — without slowing down the performance of the foreground app or draining the battery unnecessarily.

Apple I-pod

 

The Apple iPad. The name is a killing word -- more than a product -- it's a statement, an idea, and potentially a prime mover in the world of consumer electronics. Before iPad it was called the Apple Tablet, the Slate, Canvas, and a handful of other guesses.

Computer liquid cooling systems
By   posted Friday, 3rd February, 2012 2:19 AM   Comments 0

In most computers, fans do a pretty good job of keeping electronic components cool. But for people who want to use high-end hardware or coax their PCs into running faster, a fan might not have enough power for the job. If a computer generates too much heat, liquid cooling can be a better solution.


A liquid-cooling system for a PC takes advantage of a basic principle of thermodynamics that moves heat from warmer objects to cooler objects. As the cooler object gets warmer, the warmer object gets cooler.


Computer components generate heat as a byproduct of moving electrons around. A computer’s microchips are full of electrical transistors. The more transistors a chip contains and the faster they change states, the hotter the chip gets.


The thermal conductivity of liquid water is about 25 times that of air. Obviously, this gives liquid cooling a huge advantage over air-cooling because liquid cooling allows for a much faster transfer of heat.


The specific heat capacity of liquid water is about four times that of air, which means it takes four times the amount of energy to heat water than it does to heat air. Once again, water’s ability to soak up much more heat energy without increasing its own temperature is a great advantage over air-cooling.


Despite water’s incredibly superior heat transferring characteristics, there are a few drawbacks associated with it. First is the liquid coolant’s electrical conductivity. Second, is to consider the maintenance factor. Third is that the water-cooling components are much more expensive than their air-cooling counterparts.


With all these negatives, it seems like liquid cooling would be a hard sell. However, liquid cooling isn’t nearly as dangerous as it sounds, if you are careful with the materials, the risk gets greatly diminished. As far as maintenance is concerned, today’s coolants need to be replaced quite rarely, maybe once a year. As for price, any equipment that delivers top-tier performance can be justified if it’s important to you.
