IBM News: Moore's Law is at end

Report said: Moore's Law is maxing out. This is an oft-made prediction in the computer industry. The latest to chime in is an IBM fellow.Exponential growth in every industry eventually has to come to an end, according Anderson, who cited railroads and speed increases in the aircraft industry.

Intel co-founder Gordon Moore predicted in 1965 that the number of transistors on a microprocessor would double approximately every two years--a prediction that has proved to be remarkably resilient. But IBM Fellow Carl Anderson, who researches server computer design at IBM, claims the end of the era of Moore's Law is nigh.

"A generation or two of continued exponential growth will likely continue only for leading-edge chips such as multicore microprocessors, but more designers are finding that everyday applications do not require the latest physical designs," Anderson said in the EE Times' report. Anderson also cited the staggering costs of research and fabs (factories) as a formidable barrier for continued advancement. Few companies can afford chip plants that typically cost billions of dollars to build and maintain.

So, what does the future hold? Anderson cited three technologies: optical interconnects, 3D chips--which have circuits and components stacked on top of each other--and accelerator-based processing as seeing significant advancements, the report said. The latter technology, accelerators, is hot right now.

In addition to IBM, companies such as Nvidia and Advanced Micro Devices' ATI unit supply graphics-processor-based computers to accelerate scientific, engineering, and animation applications. Intel is also expected to bring out its Larrabee chip later this year or early next year that can be used as an accelerator.

They have been saying this exact same line for at least five years now, but new designs continue to hit the market.If "3D computing" is the next phase, and if this is stacking circuitry within a microprocessor, then I would suggest Moor's law will live on for a while yet. Moor never put a limitation on the physical size of an IC.

How to Find a Good Deal on Laptop battery

You're biggest helps for finding good laptop battery deals on the Internet, They are going to come from two types of sites: deal aggregators and shopping engines. Deal aggregators go out and look for good laptop battery deals from all across the web and post them in one place for their visitors to browse. Shopping engines allow you to check the laptop battery price for a specific item across all of the laptop battery retailer sites they search.
As laptop prices have dropped quite a bit over the past years so they are not as pricy as they used to be as well as laptop battery, no matter you want to buy Dell Laptop Battery, HP Laptop Battery, Toshiba Laptop Battery, or IBM Laptop Battery. If you are on a tight budget, buying a decent, cheap laptop battery can help you save money. Finding a cheap laptop battery to buy is not always easy but it's possible if you know when, where, and how to look for one.
The nice thing about deal aggregators is that they usually have some experience in looking for these type deals. That means they understand the items they list and how much they would normally cost. They also usually have a sense for when something is fishy because they know the reputable laptop battery retailers and know when something appears "too good to be true." This doesn't mean you should automatically trust a deal aggregator, but at least they should weed out a lot of cruft for you.
The other type of site is a shopping engine. Shopping engines are good for when you know exactly what kind of item you want and just want to find the best price for it. You just put in the name of item you want and the shopping engine will show the prices at several retailers and show you the cheapest price they found. For example, you can put in laptop battery, and it will show the laptop battery price at several laptop battery retailers.
You can also get a good, cheap laptop battery by buying refurbished ones. Refurbished laptop batteries are those laptop batteries that have been returned by the customers because of some minor flaws and are being re-sold to the public. They have gone through inspection and all damages have been repaired so you are 100% sure you're getting a good quality computer. They offer the quality and performance that you need for a lot lower than brand new ones. As you can see, it is really possible to find a good quality but cheap laptop battery.
You just need to know when, where, and how to find it. Keep in mind though that purchasing a laptop battery with the lowest price tag does not always mean you are getting a good deal. If it doesn't perform well, it is not worth the money.
Good luck and you will find the right laptop battery or other laptop accessories you want.

Acer Released Many Types of New Notebooks

In addition to Timeline and the 11.6-inch Aspire One, Acer decided today to announce new laptops much in the way Nikon and other camera makers roll out their PMA lineup -- in groups of eight or more. By our count, we've got at least ten different models here.
Looks like Acer has been busy readying all kinds of portable PCs to hit the market at once and today announced a whirlwind of new laptops and netbooks. In this case, a whirlwind consists of at least 10 new mobile PCs.
Give credit to news site Engadget for tidying up the entire spectrum of new releases, which includes the Aspire 5935 and 8935, both of which are 18.4-inch laptops with support for up to 4GB of DDR3 memory, biometric fingerprinting, WiFi, Bluetooth, and WiMAX. The 8935 adds 1080p output and up to two hard drives totallng 1TB, whereas the 5935 nixes full HD and can hold only one 500GB hard drive.
Then there's the Aspire 3935, a 13.3-inch ultraportable with a 1366 x 769 LED display, Intel Core 2 Duo processor, WiFi, up to 4GB of DDR3 memory, biometric fingerprinting, and an 8-cell battery. Other models include three eMachines, a pair of Gateway-branded netbooks, and Gateway's ID series, which sports a 15.6-inch LED backlit display, slot-in DVD drive, webcam with a curtain, multi-gesture touchpad, and more.
Such as Aspire 5935 and 8935: The 18.4-inch 8935 laptop can output a 1080p resolution, True 5.1 channel surround sound and houses up to two HDDs totaling 1TB capacity. The 5935 meanwhile can hold just one 500GB HDD and doesn't do full HD. Both support up to 4GB DDR3 memory, biometric fingerprinting, 802.11 b/g, Bluetooth 2.0, and optional WiMAX.
Aspire 3935: A 13.3-inch ultra portable with 1366 x 769 resolution LED-backlit LCD and Intel Core 2 Duo / GM45 express chipset. Features built-in Wi-Fi / WiMAX, up to 4GB DDR3 RAM, biometric fingerprints, and 8 hours of use with a 8-cell battery.
There's still got plenty of missing pieces here, such as pricing and availability for anything here, but one thing's for sure: we are thoroughly overwhelmed by the sheer number of new offerings.

Some Facts about Your laptop battery

These days, laptop batteries are made of lithium ion and have an average power of around 4 hours. Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which a lithium ion moves between the anode and cathode. The lithium ion moves from the anode to the cathode during discharge and in reverse, from the cathode to the anode, when charging.
We all know that a laptop battery is what makes your laptop run, an array of electrochemical cells for electricity storage, or one such cell.Without it, you won’t be able to use your laptop unless it is plugged-in directly to a wall outlet. Think of the laptop battery like the gasoline that fuels your car. Remember, laptop batteries are made of lithium ion and have an average power of around 4 hours. Unlike gasoline though, your laptop battery would degrade over the long run. Why does this happen? There are two facts that affect this; one is that laptop batteries today last for an average of 300 recharges, and second these laptop battery have a lifespan of 3 years.
If you go over these limits then your laptop battery would not operate at its peak performance.
First, since we are limited to an average of 300 charges, when you do a recharge make sure to do it when your battery is nearly empty so as to do a complete charge. If you charge your laptop battery when it is still half full then you are wasting the extra power in it while cutting back on its lifetime. The same would go if you have a Latitude D620 battery, Inspiron 6000 battery, Dell 6000 battery, Dell 6400 battery or a KD476. Next, try to minimize using your hardware. Examples of these are not to turn your LCD to its maximum brightness level and running only important programs when computing on laptop battery. The more programs you open the more power your CPU would have to draw from the laptop battery. Also, try to cut back on some unimportant hardware usage. If you aren’t using your WiFi try to turn it off. If you want to listen to music from a disk, then create a backup of the record and store in your hard drive.
But there will come a time when you really will have to replace it. If the original laptop battery isn’t available anymore then a replacement laptop battery is a good option. Ican recommend you a good place to buy it, papatek.com, there are many high quality laptop batteries in it, and also laptop accessories.Dell Laptop Battery(Dell Laptop Battery )

Sun Didn't Accept IBM Offer

If Sun goes away, java and all current undergoing opensource project sponsored by Sun will not be the same. IBM's only intentions in respect to these project would be to phase them out in favor of their own long seasoned equivalent products.
On Saturday, Sun Microsystems reportedly rejected IBM's formal buyout offer,citing the bid was insufficient and putting future deal talks at risk.
IBM reportedly made a formal bid of $9.40 a share, or less, for Sun, which in turn rejected the offer and terminated Big Blue's right to exclusive merger talks, the Journal reported. IBM, in turn, withdrew its buyout offer.
In addition to holding a belief that the bid was too low, Sun apparently was also concerned that the terms of the offer provided IBM with too much flexibility in being able to walk away from the deal.
It's obvious this deal will get a second request (for more information) from regulators. And once it does, it'll take six months, at a minimum, to a year before a decision is reached," said one attorney who specializes in anti-trust matters. "Sun can be twisting in the wind for a year." A second request for information signals to the parties antitrust regulators are formally investigating the transaction to decide whether to challenge it or not in court.When it comes to storage technology using tape drives, which amounted to $987 million in revenues for the first three quarters last year, IBM held 66.6 percent of the market and Sun a 33.4 percent share slice, according to IDC. Combined, the two companies would hold 100 percent of the tape market.
Disagreements over setting the price of a break-up fee, a penalty the suitor or target company would have to pay to undo a merger agreement, are not new and have been known to occasionally derail merger talks, the attorney noted.

AC Adapter is Indispensable Now


There is no need to say that laptop is become an indispensable thing in our life. Like most people, I’d be lost without my laptop accessories.


Of course battery life has been steadily improving over the years – and I remember when an hour was a good life from a laptop battery– it’s still not practical to use it for long without an ac adapter, and I make a point of carrying a spare in the laptop case when I’m travelling, as well as having one at home for everyday use.


That way, I can just sling the laptop in the case and go, without having to remember where I put the laptop AC adapter.The trouble is, they’re all different, so you can’t rely on the company you’re presenting to have the exact model to suit your laptop. The cost of a spare is a small price to pay for the security of knowing it will there.


It’s a lesson I learned the hard way, when I rushed out of the house for a presentation to a major client, having been up most of the night preparing the slideshow on the laptop. Arriving in the boardroom, I turned on the computer, just in time to see the “low battery” sign before the screen went blank. I felt in the bag, and my heart sank as I remembered I’d left the ac adapter on the kitchen table! Doh!Fortunately for me, they were very understanding about it and allowed me to return, somewhat sheepishly, later that day.


This was just an experience in the past, now things are much more different now. If you choose a right laptop ac adapters, it can last for a long time, the most important thing you should be careful is how to choose a high quality AC adapter, and it is also very cheap,then you needn't worry about it any more!Compaq Laptop Battery(Compaq Laptop Battery )
