In programming, memory leaks are a common issue, and it occurs when a computer uses memory but does not give it back to the operating system. Experienced programmers have the ability to diagnose a leak based on the symptoms. Some believe every undesired increase in memory usage is a memory leak, but this is not an accurate representation of a leak. Certain leaks only run for a short time and are virtually undetectable.

Memory Leak Consequences

Applications that suffer severe memory leaks will eventually exceed the memory resulting in a severe slowdown or a termination of the application.

How to Protect Code from Memory Leaks?

Preventing memory leaks in the first place is more convenient than trying to locate the leak later. To do this, you can use defensive programming techniques such as smart pointers for C++.  A smart pointer is safer than a raw pointer because it provides augmented behavior that raw pointers do not have. This includes garbage collection and checking for nulls.

If you are going to use a raw pointer, avoid operations that are dangerous for specific contexts. This means pointer arithmetic and pointer copying. Smart pointers use a reference count for the object being referred to. Once the reference count reaches zero, the excess goes into garbage collection. The most commonly used smart pointer is shared_ptr from the TR1 extensions of the C++ standard library.

Static Analysis

The second approach to memory leaks is referred to as static analysis and attempts to detect errors in your source-code. CodeSonar is one of the effective tools for detection. It provides checkers for the Power of Ten coding rules, and it is especially competent at procedural analysis. However, some might find it lagging for bigger code bases.

How to Handle a Memory Leak

For some memory leaks, the only solution is to read through the code to find and correct the error. Another one of the common approaches to C++ is to use RAII, which an acronym for Resource Acquisition Is Initialization. This approach means associating scoped objects using the acquired resources, which automatically releases the resources when the objects are no longer within scope. RAII has the advantage of knowing when objects exist and when they do not. This gives it a distinct advantage over garbage collection. Regardless, RAII is not always recommended because some situations require ordinary pointers to manage raw memory and increase performance. Use it with caution.

The Most Serious Leaks

Urgency of a leak depends on the situation, and where the leak has occurred in the operating system. Additionally, it becomes more urgent if the leak occurs where the memory is limited such as in embedded systems and portable devices.

To protect code from memory leaks, people have to stay vigilant and avoid codes that could result in a leak. Memory leaks continue until someone turns the system off, which makes the memory available again, but the slow process of a leak can eventually prejudice a machine that normally runs correctly.

Data has always been important to business. While it wasn't long ago that businesses kept minimal information on people who bought their products, nowadays companies keep vast amounts of data. In the late 20th century, marketers began to take demographics seriously. It was hard to keep track of so much information without the help of computers.

Only large companies in the '60s and '70s could afford the research necessary to deliver real marketing insight. The marketers of yesteryear relied upon focus groups and expensive experiments to gauge consumer behavior in a controlled environment. Today even the smallest of companies can have access to a rich array of real-world data about their consumers' behavior and their consumers. The amount of data that is stored today dwarfs the data of only a few years ago by several orders of magnitude.

So what kind of information are businesses storing for marketing purposes? Some examples include:

- Demographic information — age, gender, ethnicity, education, occupation and various other individual characteristics.

The RSS feed, which commonly stands for Really Simple Syndication, is an internet protocol that helps spread the availability of frequently published or updated Internet content.

RSS Benefits for an Internet Content Provider or Blogger
The use of an RSS feed saves immeasurable time for a content provider. When an interested person subscribes to an RSS feed, the owner of that feed now has a way to reach large numbers of people without having to resort to spamming techniques. The RSS feed also allows a content provider to send the requested topical information without specifically asking, every time, to those people who have subscribed. The content provider uses a program, written in XML code to make the information they post available to each person that has requested a subscription to that particular RSS feed.

RSS Benefits for the Average Internet User
The Internet grows larger by the minute. It is easy for a person to have information overload. The use of an RSS feed gives an individual more control over what information they see while on the Internet. It is also very useful for anyone that wants to stay up to date. Subscribing to the RSS feed for a topic of interest automatically provides the subscriber continued availability of the latest information on that topic. The Internet user relies on a small program called an RSS Feeder to gather the information on the RSS feeds to which they have subscribed.

Most browsers these days have built in RSS readers making that gathering the desired information easier than ever to accomplish. Joining an RSS feed is a very simple thing to accomplish.
 

RSS Benefits for Small Businesses

More and more Small Business owners are adapting targeted online marketing campaigns such as RSS Feeds in order to provide relevant content to new and existing customers. Maintaining web content such as:  company news; contests; promotional events; related articles; notifications; product launches; directories; and newsletters are examples of ways of staying in touch with customers in any niche market.  As search engines retrieve information from RSS Feeds and content is syndicated to other websites, chances of increased traffic are inevitable.  For active websites, RSS feeds are invaluable tools for small business owners.
