Inverter Air Conditioner Advantages

In many places, it is difficult to live comfortably without an air conditioner. And if you happen to live in one of those places, you are lucky because you have stumbled upon an article that talks about one type of air conditioning system the inverter air conditioner. 

You might have heard of inverter air conditioner when a door-to-door salesman who sells this kind of air conditioners knocked on your door and enthusiastically tried to convince you to buy his product. And at that time, you didn't buy the product, which is unfortunate, because an inverter air conditioner offers many benefits. Here are some of the benefits of inverter air conditioners. 

These air conditioning units are great energy savers. And in these times when a lot of people do everything they could to improve the current environmental condition, buying an energy efficient home appliance is the way to go. They use up less power or energy because when you turn them on they start slowly and change the compressors settings based on the desired temperature. 

Aside from being great energy savers, they are also money-savers. This is related to the first benefit. If a home appliance saves energy, then it means you have to pay a smaller amount for your energy consumption. Even if you have to pay an expensive amount when you first buy the unit, you will still be saving money in the long run because of the reduced electric bill every month.

They also do not create too much noise when they are running, which makes them perfect for bedroom use. You do not have to worry about waking someone up when you start the unit.

You have several brands to choose from, which include Fujitsu air conditioning unit and Daikin air conditioners. You can either buy a Daikin or Fujitsu inverter. Just take your pick.

Computer security systems vulnerable to new attacks

New York: A new category of computer attacks may compromise memory systems touted as foolproof, particularly in laptops, a recent study has found.


The study, by researchers at Princeton, found these attacks overcome "disc encryption," a broad set of security measures meant to protect information stored in a computer's permanent memory.

The researchers cracked widely-used technologies like Microsoft's BitLocker, Apple's FileVault and Linux's dm-crypt.

They described the attacks in a paper and video published on Thursday on the web.

The team said these attacks are likely to break through other disc encryption systems because these technologies have similar structural features.

The attack is particularly effective against computers that are turned on but are locked, such as laptops in "sleep" or hibernation mode.

One effective countermeasure is to turn a computer off entirely, though in some cases even this does not guarantee protection.

"We've broken disc encryption products exactly when they seem to be most important these days: laptops that contain sensitive corporate data or personal information about business customers," said Alex Halderman of Princeton's computer science department.

Halderman's Princeton collaborators included graduate students Nadia Heninger, William Clarkson, Joseph Calandrino, Ariel Feldman and Professor Edward Felten of the Centre for Information Technology Policy.

The findings demonstrate risks associated with recent high-profile thefts, including a Veterans Administration computer containing information on 26 million veterans and a University of California, Berkeley laptop that contained information on more than 98,000 graduate students and others, said Felten.

The team wrote programmes that gained access to essential encryption information automatically after cutting power to machines and rebooting them.

"This method is extremely resistant to countermeasures that defensive programmes on the original computer might try to take," Halderman said.

Slow Computer Performance - The Answers to Your Computer Speed Problems Are Right Here

What could be the main cause of slow computer performance? The most logical answer to that question is that a computer is not able to process commands in a timely manner. Usually computers think fast so when it slows down then something is wrong with its logical processes.

In this case, a computer is having a hard time looking for proper files or commands that will make applications run. There are many possible reasons and it is best to dissect them one by one.

One of the major reasons why a computer is slow is due to software problems. It is the hardware that makes a computer work but if windows has errors or there is file corruption then the fastest computer in the world will not help.

Usually computers with problems like this have a harder time processing data and instructions simultaneously. This often manifests in its slow response. Instead of considering upgrading your hard drives, memory or even your processor to assure maximum performance you need to fix these problems and before you start thinking how can I do that, it is actually quite easy to fix slow computer performance.

The major cause of a computers slow performance can be traced to the windows registry. The registry serves as a storage of all the settings and information of a computer. If there are corrupted files in the registry then these errors will cause your computers slow performance.

Since the registry stores all important information about your computer and windows is always opening and editing hundreds of settings in the registry every time you use your computer you can see how all these errors can occur.

The registry is also responsible for remembering important details of all the applications installed, including settings and how they run and if you find you keep losing program, user or desktop settings then the problem is probably in the registry. We can include the fact that there are times when files are saved in the wrong manner. This causes windows to struggle to process them fast enough and results in your computers poor performance.

To repair your slow computer you need to download a free version of a registry scanner or cleaner. Simply install and run it to scan your computers registry. This will identify and remove registry errors in your computer. Once the errors are fixed that are caused by corrupted files, you will observe a big change in your computers speed and stop slow computer performance.
