Is Freeware Lower Quality?

April 27th, 2011
Comments Off

Freeware is computer program that is available at no cost, or in other words, for free. Computer programs are generally very expensive, and some people spend more money on software than on hardware. While you cannot avoid buying hardware, you can avoid buying software by using freeware programs. This could amount to possibly thousands of dollars per year. The idea sounds great, but unfortunately freeware programs are often considered to be of lower quality. While it might be true in some cases, there are also high quality freeware programs which could save you a lot of money. Open Office is one of such programs and it is considered to be as useful as Microsoft’s Office. There are also many freeware firewalls like Comodo Firewall, which can protect your computer efficiently, and do not cost a dime. As a matter of fact, if you look around there are plenty of high quality freeware programs. Sites like download.com feature a lot of freeware programs and even have a ranking of most popular downloads. On the list you can find browsers, security programs, utility programs, chat programs, and many more. Some of the programs cost money, but have a freeware version that has slightly less features or has ads. I recommend freeware software to anyone who is on a budget, as it is better to spend money on hardware instead.

Browser Wars

September 8th, 2010
Comments Off

There are three major players when it comes to browsers: Internet Explorer, Firefox, and Opera. Both Firefox and Opera have more features and are faster than Internet Explorer, which in the opinion of many users makes them better browsers. With Firefox and Opera gaining popularity, we should ask ourselves a question: how did it happen that Microsoft lost a big portion of the market to these browsers? I believe that the reason was that neither Firefox nor Opera looked like dangerous competition a few years ago. Microsoft was simply overconfident, and did not realize that other browsers could be a threat. I am happy that there is competition in the browser market, as competition ensures that ultimately consumers have access to higher quality products. However, at the moment Internet Explorer is still being used by two-thirds of computer users. Why does it still have such a big market share?

That is because Microsoft has been bundling its Internet Explorer browser with various Windows versions for many years, and as a result most people use Internet Explorer. Does it mean that IE is superior? Not at all. Actually, in various tests it does not perform as well as Firefox or Opera, which are both fast and loaded with features. Unfortunately, there are not many users browsing the Web with Opera, even though it is often considered the best browser on the market. As a matter of fact, most Internet users might not have even heard about Opera. No wonder that some time ago Opera has presented the European Commission with an antitrust complaint over Microsoft’s dominance. It was requested that Microsoft be forced to unbundle its browser from Windows and this way allow other browsers to compete with IE.

Google Advanced Search

September 7th, 2010

If you are tired of remembering all of the commands like +, “”, -, etc. that you have to apply in Google searches, you can avoid using them by taking advantage of advanced search. The advanced search is especially helpful for those who are looking for something specific, and know what they are looking for. Some of the nicest features of advanced Google Search include:

-The possibility to choose the language in which you want to obtain the results. This will limit completely unrelated webpages. It can also help you find websites of any specific language.
-The possibility to specify the type of file in which you want Google to look for information for you. Are you looking for pdf, doc, ps, xls, or swf files? All you have to do is specify that files you are looking for.
-You can also specify that you do not want to see pages that contain any of the unwanted words which you can list. This should limit the number of unrelated websites as well.
-And finally, and probably most importantly, the possibility to tell Google Search what you are specifically looking for by filling out various fields. Those include “all these words”, “this exact wording or phrase”, and “one or more of these words”. Of course, there are many other useful options out there. I have just listed those that appealed to me the most.

Overall, search engines are probably the most useful feature of Internet, as they allow you to easily find all of the websites in the world. That is why it pays to learn how to use them effectively. While you may not want to use Advanced Search each time you are looking for something, it can greatly help you in case you are searching for something hard to find otherwise.

Before You Buy a Printer

August 29th, 2010
Comments Off

There are some things worth considering before you buy a printer. As there are many printers available on the market, you might feel overwhelmed with the choice. These are some things you might want to consider before buying a printer:

-Cost of cartridges and toners for this particular printer. That is because prices vary, and it will be a recurring expense.
-Speed, which is usually measured by how many pages per minute it can print.
-DPI (dots per inch) – the higher, the better the quality of printing. Take into account that you may not need to print using very high resolutions.
-Whether it has double sided printing or not.
-Connection type. Make sure it is compatible with your computer. The most popular connection type is USB.
-Warranty and for how long it will last. While it is hard to say how long will a printer last, you can at least carefully read the warranty.
-Check if the printer has the possibility to be accessed by many users from various PCs and devices.
-Printer’s paper holding capacity. The more the better, but a printer having a bigger capacity might cost more.

Remember to not spend a fortune, because eventually printers become outdated anyway.

Parallel Computing Model

August 28th, 2010
Comments Off

Many computers are being sold with either dual cores or quad cores. What it means is that many computers have either two or four processors. The problem that we are facing is that they are not being used effectively. Most people who have a quad core processor are probably not aware that the potential of their processor is not being fulfilled. That is because computers are not yet designed to effectively use the power of multiple processors. Let us hope that this might change as Stanford University along with AMD, NVIDIA, IBM, Intel, and HP are focusing their resources on developing new hardware-independent methods of completing parallel computing tasks. If methods that are more efficient were developed, then all of us who have processors with multiple cores would greatly benefit from it. It seems that currently many programs do not fully utilize dual and quad cores. Let us hope that this will change.

Hacked Microprocessors

August 26th, 2010
Comments Off

Generally speaking, hackers try to take control of a computer by infecting a computer with malicious software. However, it appears that there is another way that hackers might want to get access to our computers, namely, by hacking microprocessors. Last year researchers from the University of Illinois altered a computer chip to grant attackers back-door access to a computer. If hackers would decide to do this, detecting what is wrong with the computer would be virtually impossible. The way it technically works is that malicious firmware would be injected into the chip’s memory that would allow the attacker to log into the machine as if he were a legitimate user. For this type of attack to work, the hacker or his associates would have to get physical access to the processor which fortunately is unlikely. However, the possibility still exists, and it is quite scary that any one of us could be using such hardware.

Of course, it is a lot easier to defend from software threats such as viruses and spyware. In order to be well protected you should be simply using a safe browser, and have an up-to-date antivirus and anti-spyware program. Firefox is generally considered to be the safest browser so keep that in mind.

Search Engine Optimization

August 18th, 2010

From my experience I can say that some businesses know how to advertise on the Internet, while some of them do not have any idea how to do it and they never succeed. If, for example, a plastic surgeon offers quality services, it is in his best interest to make sure that he knows ways to advertise on the Net. When I think of Plastic Surgery SEO, I think of many useful tools that every plastic surgery owner can use to create his own website and market it the way it should be advertised to attract as many customers to his practice as it is possible.

Site Validation

August 5th, 2010
Comments Off

Performing website validation ensures that your website is working without any problems or errors. Having a website that has various errors is risky. That is because browsers will try to repair the error, but since there are different browsers, each of them will do it in a different way. This in turn can result in some serious problems with your site. It is a shame that there is no standard when it comes to browsers. Until there will be more cooperation between the companies that create the most popular browsers, such errors will be especially dangerous. Nonetheless, there are tools which can help you spot such mistakes:

1. A good tool for validating your HTML or XHTML is http://validator.w3.org/
2. For validating your CSS use http://jigsaw.w3.org/css-validator/
3. To make sure your readers do not have problems receiving feeds use http://feedvalidator.org/
One advice that I would like to give you here is to stick to the most popular browsers like Internet Explorer. I know that other browsers might seem to be more suitable to you, but I think that it is still too early to try to be original and have a browser that nobody else has. Most of the people in the world use Internet Explorer anyway, so try to stick with it as well for as long as it is possible.

Robots Patrolling Streets

August 4th, 2010
Comments Off

Will we reach a point in time that robots will be patrolling the streets, as security officers? The truth is that such robots already exist, as a homemade robot is patrolling an American neighborhood after dark. The robot is operated by an ex-marine who believes that the robot restores peace and increases security. He claims that no break-ins had been reported and that the park across the street feels safer. Other people claim that the robot exploits the kind of anxiety that underlies the Terminator movies, as many people are scared by this bot. The design of the bot itself is very interesting, as it is remotely controlled by the ex-marine, and the robot’s loudspeaker can be used to communicate with people. I think that utilizing robots in such fashion is a good idea, especially once people will get more used to robots. Robots should be used to perform tasks that are dangerous to humans. Patrolling streets at dark may be one way robots will be used.

Getting One Way Links

August 1st, 2010

It is important to have links pointing to your site from other people’s blogs. Such links will not only contribute to higher Page Rank, but can also bring a lot of targeted traffic. There are at least a few ways you can try to obtain such links. Your site will benefit from them, so here is what you can do:

-Submit your blog to as many directories as possible.
-Submit your articles to free article directories.

The process of submitting your blog and articles can and will be time consuming. However, there is a solution to this problem. You can purchase the appropriate software that will do it for you automatically. This will cost you some money, but if you are dedicated to blogging it will not be a problem. Additionally, if your blog generates some money, your investment will surely not be wasted. It will still take you some time to register in order to submit your articles, but you will only have to do it once. The same applies to web directory submission. Many programs already have directories listed in their database for your convenience. I know there are many webmasters taking advantage out of such software, and they claim that it is worth it.
