Perl Programming Training in San Angelo, Texas

Javascript has a lot of features which are often overlooked by web developers, and one such feature is the ability to have timed events. If you do not understand what that means do not worry because all will be explained in this tutorial.

Timing events allow you to write code which will execute within a set amount of time. As an example, say you wanted to display a clock on your web page. You could use javascripts' built in timing functions to make the time change every second or every minute.

Of course there are other uses for such functions, but we will stick with a simple timer which creates a dialog box with the words Hi There on it every 3 seconds, that way you can get a feel for how to work with timing.

To get started we are going to need a basic web page. Just create a blank page and add the following code in the script tags:

How to protect code from memory leaks?

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.

IT Job Roles and Responsibilities Explained

[Apr, 30, 2019] |

Let's face it, IT roles have evolved and are no longer meant for the IT department alone. Most departments tend to have a technical person that can help make sense of data. These days, businesses encourage data democratization, meaning that everyone in the business is responsible for the information that the organization receives. Departments no longer have to wait for data to pass through IT before they receive it. The departments get information as it comes. Then, they make decisions based on that data.

IT Job Roles and Responsibilities

1. Project Manager

A project manager, in this case, is someone that plays a managerial role in a company’s project. In fact, this is one of the most important IT job roles. The manager is responsible for his or her team. He or she makes sure that deadlines are met, and the project proceeds as planned. It mainly includes planning, design, initiation, monitoring, execution, and control.

2. IT Director

In most cases, the term director is associated with big positions in a company, and is often associated with a board role. As one of the top IT job roles, the IT director is responsible for planning, managing and executing the core-infrastructure of a company. The primary role of the IT director is to oversee all the technology operations within the firm. The director then evaluates what his or her team does to make sure that the activities are in line with firm’s main objectives. On top of that, the IT director makes sure that all departments have their technology needs met by his or her team.

3. IT Manager

The rank of an IT manager is definitely lower than that of a director, however, the role is still very crucial for any IT department. Every IT department has staff members that are meant to deliver results at the end of the day. The IT manager supervises most of the workers in the IT department. He or she is in charge of motivating them and making sure that they do what they are supposed to do. The IT manager’s roles include monitoring, planning, coaching, disciplining employees, and counseling.

4. Software Engineer

This position can also be referred to as a software architect, system engineer or application programmer. The main work typically involves creating and programming system-level software such as database systems, operating systems, and embedded systems. Their primary role is to ensure that they understand how both software and hardware work and to use them appropriately. However, the responsibilities don’t stop there. The software engineer is also required to interact with both colleagues and clients to explain which system or solution is going to be more suitable for use.

5. Systems Analyst

A systems analyst can also be called a solutions specialist, product specialist or a systems engineer. Their primary work mainly involves identifying, analyzing, and coming up with new information systems that will provide a viable solution. This is mostly done as a response to the requests of customers or just for the business. They also have to make sure that they determine the costs and total time required to bring the information systems into effect.

6. Helpdesk Support

There are times when your team could encounter system problems. Perhaps, a piece of hardware or software has malfunctioned. You need helpdesk support to deal with such issues. This is a professional that knows about common computer problems. Without them, business operations could stall because an employee can be stranded, and there’s no one to help.

7. Network Designer

As much as helpdesk support can solve most IT problems, there are other issues that they can’t solve. You may experience system shutdowns or slow internet. In that case, you need an expert in maintaining communication systems. These professionals will also be responsible for setting up cyber security systems for the organization.

IT involves many job roles and responsibilities that all work hand-in-hand to deliver results. As you begin your business, you should know about these roles so that you can know which ones are going to be the most suitable for your firm.

E-books vs Hard Copies

[Aug, 10, 2012] |

There has been and continues to be a plethora of observational studies by different researchers in the publishing industry focused on how e-books have affected hard-copy book sales. Evidence from these studies has indicated that there is a significant and monumental shift away from hard-copy books to e-books.[1]These findings precipitate fears that hard-copy books might become more expensive in the near future as they begin to be less available. This scenario could escalate to the point where only collectors of hard-copy books are willing to pay the high price for ownership.

The founder of Amazon, Jeff Bezos, made a statement in July 2010 that sales of digital books had significantly outstripped U.S. sales of hard-copy. He claimed that Amazon had sold 143 digital books for its e-reader, the Kindle, for every 100 hard-back books over the past three months. The pace of this change was unprecedented; Amazon said that in the four weeks of June 2010, the rate of sales had reached 180 e-books for every 100 hard-backs sold. Bezos said sales of the Kindle and e-books had reached a "tipping point", with five authors including Steig Larsson, the writer of Girl with a Dragon Tattoo, and Stephenie Meyer, who penned the Twilight series, each selling more than 500,000 digital books.[2] Earlier in July 2010, Hachette said that James Patterson had sold 1.1m e-books to date.

According to a report made by Publishers Weekly, for the first quarter of 2011, e-book sales were up 159.8%; netting sales of $233.1 million. Although adult hard-cover and mass market paperback hard-copies had continued to sell, posting gains in March, all the print segments had declined for the first quarter with the nine mass market houses that report sales. Their findings revealed a 23.4% sales decline, and that children’s paper-back publishers had also declined by 24.1%.[3] E-book sales easily out-distanced mass market paperback sales in the first quarter of 2011 with mass market sales of hard-copy books falling to $123.3 million compared to e-books’ $233.1 million in sales.

According to .net sales report by the March Association of American Publishers (AAP) which collected data and statistics from 1,189 publishers, the adult e-Book sales were $282.3 million in comparison to adult hard-cover book sales which counted $229.6 million during the first quarter of 2012. During the same period in 2011, eBooks revenues were $220.4 million.[4] These reports indicate a disconcerting diminishing demand for hard-copy books.

Tech Life in Texas

Austin may be considered the live music capital of the world but the field of technology is becoming the new norm in the The Lone Star State. Home to Dell and Compaq computers, there is a reason why central Texas is often referred to as the Silicon Valley of the south. Itâ€™s rated third on the charts of the top computer places in the United States with a social learning and training IT atmosphere. Adding the fact that Austin offers fairly inexpensive living costs for students, software developers may take note as they look to relocate.

The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time. Tom Cargill
