The Importance of Decoupled Objects in OOP

In OOP (object oriented programming) it’s important to remember why you are building an application with objects instead of mere functions (procedural programming). Sometimes programmers will treat objects more like functions which completely defeats the purpose of objects in the first place! The purpose of this post is to explore the real benefit of OOP and how to structure your models appropriately.

What is a decoupled object?

Contrary to the novice OOP programmer’s belief, an object is much more than a collection of data members and related methods. It’s important to remember that an object embodies data and methods that pertain only to itself. The term “decoupling” is used to identify the separation of software blocks that shouldn’t depend on each other.

Why is it important to decouple objects?

Let’s say that we have a Car Class with the methods driveForward(), stop(), turn(), honkHorn(), and changeLanes(). This object has a poor design because one of the methods, changeLanes(), might depend on a Street class. What if you were trying to reuse this class for a car that only drives off-road? In this case, the changeLanes() method is completely meaningless to your object instantiation. Furthermore, if the turn() method were to reference the changeLanes() method, the entire object would start to seem too specific to instantiate and work with an off-road car. In addition, if a change is made to the Street class, it’s very likely that the Car class will also have to be modified. Since Car has a method that depends on another object, this object is said to be “coupled” (which is what we are trying to avoid).

How to decouple objects

To create what I call “purified objects”, we need to completely decouple them in such a way that all of their fields and methods are specific to what the object can do in any circumstance. To decouple the Car class, you would want to move the changeLanes() method to another object that interacts with Car, like CityDriving. This new object acts as a mediator because it uses the Car class for special circumstances without tainting its pure definition.

When designing your object models, ask yourself “are these objects purified? Are they decoupled?” If you religiously ask yourself this question when creating new objects, not only will you end up creating much cleaner code, you’ll also spend less time re-factoring. Good luck!…

How to Speed Up Your Computer Without Spending Any Money

There is a very common scenario that occurs in computing, people buy a new computer and it runs fine and dandy for the first few months, gradually it becomes slower and slower and eventually the speed is unbearable. Why does this happen? The most common cause is a build up of extra processes and software running in the background that consume all of your system resources, leaving very little free for programs that you want to use. Of course there are other reasons behind a computer running slow so let’s take a look at them and what you can do to speed it back up again.

System Resources – These are typically defined by your memory and processor. The available system resources are used when you load up a program. If the amount of available resources is low then this is when you will notice slow response times and even system crashes. If this happens you are going to need to free some up. Firstly go to add and remove programs and delete any old ones that you no longer use, a lot of the time programs will auto-load when Windows starts up and therefore consume system resources. If you never use the program then this is a waste.

A very handy tool is the task manager. If you right click in your windows taskbar and choose task manager you can use the processes and performance tabs to keep an eye on how much memory and CPU usage your system is using. By using the processes tab you can identify which programs are using the most system resources and consider removing or disabling them if you don’t use them.

Finally a great way of freeing up valuable resources is by using the msconfig tool (you can type msconfig in the search or run box in windows to load it). The startup tab will show you what programs will load when Windows starts up, you will usually be able to identity which ones are needed and which aren’t, disable the ones you don’t use. After doing this you should notice a definite increase in available resources when you next restart your computer.

Hard Drive Maintenance – Your hard drive is where all your data is stored so ensuring that it is running properly is key to fast loading data. Slow response times on your hard drive are a very common cause for slow loading programs and files. To ensure this doesn’t happen you should regularly perform a clean up on your drive. This means going through your files and removing old files and folders you no longer use. Also try to do a disk cleanup to remove old temporary files. Depending on how much usage your hard drive gets, a disk defragment can make a big difference in drive response times, so try to run one of these every few weeks.

Spyware and malware checks – Spyware, malware and adware can not only put your data and privacy at risk but …

How an Audio Driver Works: Simply Explained

Are the words hyper text mark-up language and World Wide Web already triggering a headache? Some people are not really that computer-savvy and smart when it comes to details regarding drivers, software, and hardware, especially those who belong to the earlier generations. But being a non-computer graduate doesn’t mean that one must be totally computer illiterate. Gaining knowledge about how the computer works, even just the basic ones, can save one the effort and money of giving the computer technician a call every time there is a problem.

Ever wondered how it works? Then today is the right time to know. Here’s a simple guide on how an audio driver works, explained in a very simple way, so that those who are not that familiar can still catch up with the world.

An audio driver is a kind of driver for sound devices. A driver is software or a program that enables the computer to communicate with its hardware or other external devices. It is somewhat a medium for a certain device to work.

It is just like in the human body, before the body can execute any action it must first be at the command of the brain. For example: if a person wants to jump, the brain must first send signals to the specific organ for jumping (leg muscles and skeletons) through the spinal cord that it wants to jump. Now, the spinal cord serves as the medium for the brain and the legs to communicate. When the leg receives the command from the brain through the spinal cord, it will then do the action. A driver works as easy as that.

It works by letting the sound card/audio card, a computer expansion card that serves as the facilitator of audio inputs and outputs to and from the computer, to communicate well with the speakers. If the audio driver is incompatible with the sound card or is outdated, then it’s more likely that the speakers will not function properly or it would create low quality sounds. Now that’s how an audio driver works. Simple, isn’t it?

That is why going for it is really a great investment. However, with the unending flow of driver downloads swarming the Internet, the chance that one would end up downloading the correct and the best audio driver is so slim. But don’t fret yet – because there is a solution to this problem.

One of the best and the easiest ways to find the best audio driver is to have the best driver software database program. In the plainest definition, a driver software database program is a program that will help a person find the most updated and compatible audio driver for his or her device. And yes, this will come a little handy because if one has installed the wrong driver, a device will not work properly. Finding a reliable website or program that will find one the best audio driver is indeed, heaven sent.

Lastly, installing a good audio driver …

Off the Shelf or Custom Software Solutions – Which One Is for Your Business?

Business organizations often look for solutions that can help them to reduce their expenses. And for this, they hire software development companies that offer two types of software that suits their IT requirements. The first one is off the shelf software that is a ready-made application available and can be bought directly and used by the organization. The other one is the application that the software company builds as per the specific needs of the organization. Both the solutions are different in terms of development and manufacturing.

What are customized software solutions?

Now the point is, during the period when business organizations make efforts to gain a firm foothold in the competitive market, any stereotypical product offering same age old functionalities may restrict their growth chances. It is for this reason that hiring a customized software development company is the most excellent choice at the moment. The prime goal of such companies is to create a precise end product that can meet the demands of the customers. Suck bespoke solutions are created only after clear understanding of the preferences and requisites of the client.

Customized packages are usually built by using the most recent technology. The software is developed in steps and any disliking or difficulty of the customer is taken into consideration and is rectified during the formulation of the application and this is the most important advantage of developing such customized applications.

Tailor made products often demand strict inspection and analysis till the final product is developed. Off the shelf products may lower the levels of expenses than the custom software, but the latter is always a better choice as it is beneficial in the long run.

Some major differences between customized software and off the shelf solution:

Cost of the software: The most prominent difference between the two solutions is the price of the application. Off the shelf software is usually cheaper than customized solutions because ready-made software is a mass production and their cost is distributed among several buyers, but custom solutions are developed for specific clients to fulfill their unique needs. So, the entire cost of development has to be borne by the buyer.

Development methodology and usage: Off the shelf solutions are usually made for general purposes and they target one segment of the business, but are unable to fulfill any particular requirements of the organization. The client often needs to hire custom software development company in India to make essential adjustments in the software and to implement it. Since the solution is developed around the exact requirements, it is completely suitable and compatible with the processes of the organization. Employees who have to use this software also get accustomed to the system within few days. This is another reason that attracts organizations to develop customized solutions.

Software updates: One of the major problems with off the shelf software is that it becomes very difficult to update the solution as the technology changes. To make any changes in the software, the organization has to …
