Advantages of Open Source Software

PHP-Nuke, PHP PostNuke, TikiWiki, Xoops, b2evo---you can find them everywhere in the web. These are all the open source software solution used in various areas of web applications. These are most of the time free applications released under special licensing terms. This allows the coding to be shared by all and edited to suit the unique needs of the user.

What is the secret behind this immense popularity of all these software? The use of open source software has some practical benefits. Let us discuss about them in details.

You get the core framework for free

For a start up company, budget is a major factor. You can save on your initial investment cost by adopting open source software which comes free of cost.

Modification benefits

With Open Source software, the code is openly available and that enables the users to fine tune the codes to suit their needs. It also contributes to the improvement of a software product by making it adaptable to changing conditions, fixing of bugs, security problems and so on.

Excellent support base free of cost

With open source software you are not tied to a single company or do not need to fall back upon it for fixing all your application related problems. This dependence proves to be very expensive. But with open source software, you get the support of the entire support community on which these applications grow and thrive.

Forking leading to a new product

The open source software keep open the possibility of forking when the existing code base does not work thus leading to the creation of a new software altogether.

The entire online community is indebted to the various open source software for what they have contributed to transform internet into a vast collaborative community that it is today. With an array of open source software, you may conclude that the days of commercial software are numbered. But it requires time for their installation, implementation and trouble shooting. If you lack the time then you have two options---go for the expensive commercial software or hire an efficient and renowned web host who will tackle these problems for you. The second option is definitely better.

How To Correct A Continually Rebooting Computer?

When you sit down at your computer desk and press the power switch on your desktop, the last thing you want to experience is a continually rebooting computer.

There are a variety of causes that contribute to this problem, from something as simple as a stuck power button to a much more serious problem as your power supply slowly failing. Other causes for this problem may be overheating PC components, or viruses affecting your system.

Now, if you’re like the rest of us, having a computer that reboots constantly is not our idea of a productive day. So how do you diagnose this problem and where do you start to to make corrections. Here are some common but often overlooked causes and solutions that will get your system running again.

First take a look at the power button and see if its stuck in the socket. If so, you may be able to simple tap the front of the case to release the button. In some cases, you may have to remove the system unit cover to get the button to return to the out position.

If you cannot stop the computer from rebooting by pressing the power button and releasing it, turn off the power switch in the back of the computer next to the power supply. If your power supply do not have a power switch, you will have to unplug the system from the wall outlet.

This must be done as soon as possible so that the constant rebooting will not damage components such as the hard drive. Constant rebooting also have the danger of power surges that can further damage larger components such as the motherboard.

Second you check your computer’s software by checking to be sure no virus or malware have not effected your hard drive. Virus and malware are small software that is downloaded along with other files that is designed to cause mischief.

To remove any viruses and malware, use a anti-virus program that will search your hard drive and remove these file quickly. These files can cause such damage as wiping your hard drive of all data or hijacking your web browser so you have no control over your online surfing.

If you find no malware on your computer, take a look at your BIOS to see if it has become unstable or has been changed. BIOS stands for Basic Input Output System and is a small program designed to check all components for proper operation when the computer is turned on.

If your BIOS has been changed or if you’re not sure if its been changed, try to reset the BIOS settings to the default settings after you access the BIOS as the computer reboots.Once inside the BIOS, you should have the option to load your default settings, save the change, and reboot the computer.

However, there are times when a continually rebooting computer will not allow you to access the BIOS. You can then reset the BIOS by removing the system unit cover and locating the jumper on a three pin header.

You must consult your computer or motherboard manual to properly perform this procedure and it should be done as a last resort. Before making any changes to your BIOS, you should backup your BIOS if your computer reboots at long intervals.

After checking your computer’s software for its rebooting problem, you must check to be sure hardware is not at fault. This problem may exist because one of your memory modules are unseated from its socket . Memory modules are long, narrow sticks that attach to the motherboard.

Remove any static electricity from yourself, remove the system unit cover and check these memory modules to be sure they are secure. Check the connections to the hard drive and the connections leading from the power supply.

Power supply connectors should be checked if you’ve done work inside your computer recently. Power Supplies are known to slowly fail and lead to rebooting problems. There is no way to check an ailing power supply and this should be considered the problem as a last resort.

Following these steps will help you correct any computer that continually reboots itself. If no virus or malware is found, carefully and thoroughly check all connections. And if the problem still exist, the most likely cause would be the Power Supply.

Which Tool to Use for Listening to Your Audio Books?

The beauty with audio books is that you have more than one option for listening to them.

For those of us who like to be given lots of options for doing certain things instead of being forced to adapt to just one choice, you definitely have lots of options for listening to your audio book.

If you are someone who likes listening while seated on your favorite couch or seated on your desk, listening to your audio book on your cassette tape player (if the audio book is in audiocassette format, of course) is the option for you.

But if you have a desktop or laptop computer, you might prefer listening to your audio book from here.

Most PCs have Digital Audio Players for playing audio books. If your PC doesn't have any (very unlikely), you can still download them completely free on the Internet. The 2 best digital audio players that you can download free from the Internet include:

RealOne Player: It can be downloaded from their website:-
http://www.Real.com

Windows Media Player: It can also be downloaded from their website:-
http://www.Microsoft.com

But if you would rather listen to your audio book while doing your household chores, dancing, exercising, jogging, commuting to and from work, etc, then you would need portable audio playback devices that you can carry around and listen to, preferably with earphones.

With the ever expanding market of portable audio playback devices, it goes to show that more and more people are now using them, because of the wonderful benefits they provide.

The most common form of these portable audio playback devices are the normal audio CD players or CD-ROM devices. You can carry these around with you while you do your household chores, exercise, jog or commute to and from work.

The more advanced form of these portable audio playback devices for playing audio books, especially those for listening to downloadable audio books, include:

-- Audio-ready PDAs (Personal Digital Assistants). Some of these PDAs include Casio CASSIOPEIA and Compaq iPAQ. Both can be pretty expensive, costing as much as about $500 for the Compaq iPAQ and about $400 for the Casio CASSIOPEIA.

-- Compatible Portable Audio Players. Some of these include the Creative's NOMAD Jukebox 3 and the SONICblue's Rio 900. These are cheaper than PDAs. For example, you can get the SONICblue's Rio 900 for about $250 from sites such as Sonicblue.com

Finally, like I said at the start of this article, whatever tool you decide to use in listening to your audio books will depend largely on "how" you prefer listening to your audio books.

For example, for the "young and restless" teenagers they can't do without the PDAs. I bet you wouldn't too if you were their age, right? But for the "aged and rusty" who just prefer the ease of being seated on their favorite couch, nothing can be better than listening to their favorite audio books from their "good old" cassette tape player!

What is the Best Method to Back up Data?

This being the age of internet, chat rooms, blogging and innovative hackers, their expectation never gets fulfilled. The news always leaks out or is methodically publicised by a rival or a gleeful hacker. Thereafter, insult is added to their injury as irate customers and the eager press demand explanations about every unsavoury detail of the incident. But data loss is not a problem affecting only the big players only any more. All of us deal with some amount of data and almost all of it is important to us. Albums have been replaced by .jpeg files, our music is inside the hard drive of our pc or laptop, and our emails are stored in offline folders or software like Microsoft Outlook. Students keep their study material in their machines, and a doctoral thesis is usually a file on the hard disk instead of being a thick volume bound in leather covers. It is, therefore, strange that we keep losing data because we have not taken the precaution of backing it up elsewhere. Several start-up home businesses have not seen the light of the day anymore after an initial incident of data loss. All of this underlines the importance of backup, which really cannot be overstressed.

Some Methods of Obtaining Backups

The method, or rather, the medium chosen for backing up data will depend on the volume of data to be stored, as well as the nature of the data. Some common methods are being enlisted below:

CD and Floppy: The floppy has largely gone out of use by now, due to its many limitations, small capacity and security problems. The CD is a good choice for obtaining backups, and is one of the favourite choices in both domestic and corporate spheres. It is cheap, readily available, portable and compatible with several file formats. Storing a CD and sharing information from it are also quite simple.

DVD: The DVD is a good choice for storing audio visual information. It may not be as cheap as the CD, but offers better quality, often lasts longer, and has way more space. DVD RWs can be used in such a way that literally every bit is used to store information. A DVD also has the same facilities when it comes to sharing and easy transporting. However, the DVD RW, many market observers feel, may turn out to be an intermediate technology and be replaced by something superior but very similar in function, or may evolve in such a way that the problems would get solved. It must be noted here that the constant research in this regard, and inventions like the Blue Ray disk etc. point out that we can hope for a better technology soon.

USB Devices: These are the new favourites all over the world. The greatest proof of the popularity of this technology lies in two facts. Firstly, the storage space of pen drives / flash drives/ memory sticks is constantly increasing. Secondly, their prices are plummeting downwards rapidly. Almost all kinds of files can be stored on these; they are very easy to carry, do not require a separate software or booting up of the machine to start functioning, and it is very convenient to share the data stored on them. For storing smaller music libraries, an iPod may be an option too.

External Hard Drives: For larger data storage requirements, external hard drives are excellent solutions. Arrays or stacks of hard drives are available for corporate purposes and are provided by all good hard drive manufacturers. Seagate, Maxtor, ASB, LaCie all make external hard drives of varying capacities and prices.

Online and Offline Storage Spaces: These are ‘spaces’ provided by professional firms, and are extremely secure for sensitive data storage.

Tapes and Printouts: Traditional storage should not be left out of the list. There is some information that one simply needs to see on the good old piece of paper. Tape has been in use for a long time now, and will probably continue for some time.

Top 5 Ways To Make A Computer Run Faster

Today I am going to be talking about different ways you can make a computer run faster. There is actually a lot you can do yourself that will boost your PC's performance. So lets take a look at different ways we can remedy that slow computer of yours!

1. Free Up Disk Space

A great way to make a computer run faster is to free up some disk space. Windows comes with a disk cleanup tool that helps you free up space on your hard disk. The utility identifies files that you can safely delete without messing anything up, and then enables you to choose whether you want to delete some or all of the identified files.

How to use disk cleanup tool.

* Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.

* In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list. (If you have multiple hard drives you will have to select which one to scan.)

* Clear the check boxes for files that you don't want to delete, and then click OK.

* When prompted to confirm that you want to delete the specified files, click OK.

2. Use Defrag Tool

When you add a file or a new program to a new computer, the hard drive is relatively empty so new data is saved to the hard drive in one whole block. When you need to use that information, the computer can quickly access it because it is all in one place. Defragging your system is definitely a way to make a computer run faster.

How to use defrag tool.

* From the start menu point to "all programs"
* Point to "Accessories"
* Point to "System Tools"
* Click on "Disk Defragmenter"
* The disk defragmenter will display the hard drives on your computer. Just select and click Defragment.

3. Get rid of spyware

Definition

Spyware is software with malicious intent - by design; it does something bad to your computer. Usually, it gets installed without your knowledge. It sometimes takes advantage of the fact that most people click "I Agree" to software licenses without reading them.

The only way to get rid of spyware is to have some kind of scanner, sort of like an anti-virus. In order to make a computer run faster and keep it safer your going to need an anti-spyware program. This is tricky, a lot of the spyware programs out there are malicious and will actually add viruses and spyware to your computer by using the "spyware scanner and blocker". So please remember to be very careful when choosing your anti-spyware program.

4. Find and repair disk errors

Detect and Repair Disk Errors

In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.

How to run the error checking utility.

* Click Start, and then click My Computer.
* In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
* In the Properties dialog box, click the Tools tab.
* Click the Check Now button.
* In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
* If bad sectors are found, choose to fix them.
Tip: Only select the Automatically fix file system errors check box if you think that your disk contains bad sectors.

5. Get an external hard drive

Adding an External Hard Drive to your computer will allow you to clear out a lot of the things you don't need to be storing on your normal hard drive.

A great example would be your music or pictures. All those songs and pictures are sitting on your computer making it go slower. You will see a decline in your computers performance as soon as you use over half of your hard drive space.

Moving all your songs or pictures to your external hard drive will free up a lot of space on your main hard drive. You can even move applications such as photoshop or games.

An external hard drive is also handy because it is portable. You can unplug it from your computer and take it to a friends house and plug it in there, sharing photos and pictures very easily.

This is truly a great way to make a computer run faster.

Factors To Think About When Choosing A Broadband Internet Service

Undoubtedly, broadband is the future of internet, but there are other ways of getting onto the internet. If speed isn't something that you need to have, you may want to look for a company that offers dial up service. It is much slower than the broadband but it can be much cheaper. It isn't good enough if you need to download large files or watch videos, but if you just need to write email or get information from the internet, it can work just fine. Broadband internet providers, especially some of the smaller ones will more often than not offer dial up as well. The idea is that you don't have to pay for a service that you don't need. As a person deciding on a service provider, consider what the service will be used for and then make a decision to use broadband or dial up services.

However, if you decide to change from dial-up to broadband internet either because of business needs or for faster surfing speed at home. By and large, broadband internet refers to permanent connection at 256 Kbps or any transmission that is higher than that.

There are two significant benefits that a broadband internet can offer you. You are automatically connected to the internet by once you turn on your computer. Broadband providers usually offer unlimited surfing package, which means you can surf as long as you want for one flat price.

Hundreds of service providers offer broadband internet promising clients of "super fast" access to the internet. This can be misleading because some service providers do not meet these promises. That's why it is imperative to consider a few things before getting a package for your broadband connection.

How Broadband Speed Affects Your Internet Experience

When you acquire a broadband service, one of the things you often need to think about is the speed of broadband service being offered to you. Although your broadband provider may attempt to make it appear as if it's vital to have the fastest speed, you need to think about your needs for what you want to do with your Internet connection. Understanding your personal needs in broadband speeds will prevent you from buying too much or too little. Certainly, what most savings-minded people are interested in knowing is when broadband speed enters the realm of being too much. Generally speaking, if you're simply browsing the Internet, then you will enjoy the speed of broadband, but don't need to purchase the fastest connection possible. Most text-based documents such as e-mail, news sites, and similar sites, simply don't need connections that are superbly fast.

If you begin doing other activities, such as downloading music and watching online videos, then you might want to get something slightly faster than the basic broadband speed. Remember, a little goes a long way. But generally speaking, the amount of data any single web page will transfer information to you at will be at a slower speed than your broadband connection, so there's potential for wasted bandwidth.

In some situations, you may realize that you don't have enough broadband speed to support your activity. However, these are the extreme cases. If you have many Internet users who like to use the Internet at the same time, such as having high school students who regularly enjoy playing video games over the Internet, you will absolutely desire a faster connection. If you make many peer-to-peer downloads, download a lot of videos and music, or browse numerous pages at one time, you also may need a faster connection.

Last but not least, another thing to think about when deciding on what bandwidth speed is your upload speed. This will have an effect on any data you send out to the Internet, including sending e-mail, transferring files to remote servers, and hosting web pages. Generally speaking, if you plan to run your own website, get broadband with fast speeds for uploads. Or, better yet, have a remote hosting company host your website at fast speeds without increasing the price for your home connection. On the whole, for both uploads and downloads, you should cautiously assess how heavily you intend to use the Internet and purchase accordingly, and you'll end up getting what's just right for you.

Forget Emailing Pictures - Use Free Online Photo Hosting Websites
