How to increase Computer Performance?

How to increase Computer Performance?



Do you find that your computer is suddenly running very slow, and you wished you knew the reason why?
There are some reasons through which your computer can suddenly slow some are given below:


Reason #1:Errors In The Computer Registry Files:

It is found that almost every computer will run into speed problems if the computer registry is not cleaned regularly. The registry contains files that carry instructions for your computer to run correctly. If these files are not maintained, it is almost certain that there will be errors in them if the computer is used regularly.

How To Clean The Registry Files from your computer?

To keep your computer running optimally, it is important that you maintain your registry regularly. To do that, you should download cleaner software. This was what I did to restore my computer back to its original speed again

Reason#2: Virus Infection in your computer

Your computer might be infected with a virus, causing it to run slowly. In this case, you will need to scan your entire hard disk with an anti-virus software, especially targeting the files that you have downloaded from the internet. These files can include your email attachments as well.

 Reason#3: Spyware & Adware Infection 

Spyware and adware infections are common on computers, but it will take a lot of spyware to actually slow down your computer. Spyware are programs that track what you do online, and report back to the sites that they came from. Users whose computers are infected by spyware have no idea that they are being watched.
To clean out your computer's spyware, you can download a spyware cleaner, like Spybot Search And Destroy, from the internet, and run the software.

How to Determine the Quality of Software / Web Applications

April 25, 2011 Add Comment
It is not easy to determine the quality of a software or desktop and web applications. Techniques how to determine the quality of software continues to grow in accordance with the development of technology today.


If we look for bugs in the software, we actually will not know exactly how many bugs are contained in it.

Constraints in How to Determine Software Quality


Here are some points that become the reason why determining the quality of software is not easy.
If a programmer tests the program for his own work, the tendency to assume that the program he created is really good could happen. This does not mean that programmers should not test. Testing is limited to unit testing only.

Testing a software takes a long time. So, if the programmer also perform testing then the main task, that is making a program, should be postponed first.

When a programmer tests generally he tends not to record the errors found. If it is done it can happen that bugs that have been found are not fixed.

If we examine further, to get a good software quality, separate program tester is required. However, even if there is a tester, testing can not guarantee the quality of good software.

This depends on several things like good test case design, which can cover almost all possible program errors that occur.

Improper test case design will cause escape test. Escape test can occur because A low fidelity test system, testing the system that includes almost all the features but the very important feature is not tested.

Usually this happens because of poor engineering. The second possibility is the occurrence of a regression test gap, ie the test case does not include where the bug was found. Generally this happens because of limited time or resources.

To manage your software development properly, visit the " How To Manage Application Software Development " tutorial .

Conclusion How to Determine Software Quality


To get a good software quality needs a special division for software testing.

The design of the test case plays a role in determining the quality of the software, when the design of the  test does not cover all the important features, so it can happen low fidelity test or regression test gap. Both of these cause the bug to pass the test.

The purpose of the testing division is to not only look for bugs. The scope of this test includes the performance of the software viewed from the response time when the amount of data and its users a lot, reliability reliability of a software, security, efficiency, and maintainability.

Develop Websites with Bluefish in Ubuntu



Linux is at the forefront of web development, and Ubuntu is a great distribution to use to build and design a website for the first time. Recently, I've been developing web applications using frameworks, and Linux in general makes these things quite a bit easier. Therefore, I figured I should present some of the basic tools you can use to create, develop, and host a website. This may abstract a bit away from the idea of "applications" in and of themselves, but I thought you may all be interested anyway.

The most logical first step for most users is selecting a development environment. Today, I'll highlight Bluefish. Later on, I'll focus on a WYSIWYG editor. (Which, by the way, is kind of difficult to find. Please, if you have any ideas, leave a message in the comments.)

Of course, to put your webpage on the Internet, you'll probably want to use a reliable web hosting. There's about a million out there, and it's hard to figure out the differences between them. I used to have a site on Bluehost, but I eventually cancelled because I thought their support was poor, and I didn't want to fax in a copy of my driver's license just to have SSH access so I could use Rails. I switched to ThinkHost a few months ago, and I've been really happy thus far. They offer reliable Linux hosting with unlimited bandwidth, space, and domains. Better yet, the servers are powered with wind and solar energy, and they plant a tree on your behalf.

Bluefish is a code editor, so users should have a basic understanding of XHTML and CSS, along with any other development languages. I learned HTML rather painstakingly from an outdated code reference, and I don't recommend you do it that way. Instead, try HTML & XHTML: The Definitive Guide published by O'Reilly, which can help even the most talented developer learn new tricks. In fact, it taught me all about the <label> tag, and I felt kind of dumb for previously embedding form labels in only a paragraph tag and wrestling with CSS, but alas...




One of the nicest things about Bluefish is that it uses 30 to 45 percent less memory than other editors. This makes quick edits less of a hassle. Sometimes, other editors can be too clunky, and I found myself reverting to a console-based text editor to make a minor change, but Bluefish should stop this from happening. It has built-in project support, so you can easily open multiple files and keep them organized in the right path. It has all the standard stuff, like line-numbers, search and replace, and code highlighting for languages like HTML, Ruby (go Rails!), Python, and PHP. Best of all, the menu bar allows you to instantly drop in code that developers use often.
Bluefish allows you to connect to a remote server and edit files, so here's a quick guide to using Bluefish with ThinkHost. This tutorial assumes you are using GNOME, though I'm sure you can do the same thing with KDE.
Click on the "Places" menu, and select "Connect to Server...".
In the dialog box, type in your FTP address in the "Server" box. You should be prompted for a username and password.
Now, open up the mounted server in Bluefish, and now you can easily edit and save all of your files on Thinkhost.
