I will begin our blog on Java Tutorial with an incredibly important aspect of java development:  memory management.  The importance of this topic should not be minimized as an application's performance and footprint size are at stake.

From the outset, the Java Virtual Machine (JVM) manages memory via a mechanism known as Garbage Collection (GC).  The Garbage collector

  • Manages the heap memory.   All obects are stored on the heap; therefore, all objects are managed.  The keyword, new, allocates the requisite memory to instantiate an object and places the newly allocated memory on the heap.  This object is marked as live until it is no longer being reference.
  • Deallocates or reclaims those objects that are no longer being referened. 
  • Traditionally, employs a Mark and Sweep algorithm.  In the mark phase, the collector identifies which objects are still alive.  The sweep phase identifies objects that are no longer alive.
  • Deallocates the memory of objects that are not marked as live.
  • Is automatically run by the JVM and not explicitely called by the Java developer.  Unlike languages such as C++, the Java developer has no explict control over memory management.
  • Does not manage the stack.  Local primitive types and local object references are not managed by the GC.

So if the Java developer has no control over memory management, why even worry about the GC?  It turns out that memory management is an integral part of an application's performance, all things being equal.  The more memory that is required for the application to run, the greater the likelihood that computational efficiency suffers. To that end, the developer has to take into account the amount of memory being allocated when writing code.  This translates into the amount of heap memory being consumed.

Memory is split into two types:  stack and heap.  Stack memory is memory set aside for a thread of execution e.g. a function.  When a function is called, a block of memory is reserved for those variables local to the function, provided that they are either a type of Java primitive or an object reference.  Upon runtime completion of the function call, the reserved memory block is now available for the next thread of execution.  Heap memory, on the otherhand, is dynamically allocated.  That is, there is no set pattern for allocating or deallocating this memory.  Therefore, keeping track or managing this type of memory is a complicated process. In Java, such memory is allocated when instantiating an object:

String s = new String();  // new operator being employed
String m = "A String";    /* object instantiated by the JVM and then being set to a value.  The JVM
calls the new operator */

JAVA SCRIPT TUTORIAL – THE ESSENTIAL ELEMENTS

If you are looking to increase your proficiency in programming, it can make a lot of sense to invest some time into learning how to use JavaScript, or taking a Java Script tutorial.  It is one of the most popular and powerful options available today for people to use in programming different parts of their websites.  It often finds use in headers, or in interactive features displayed on pages.  It allows you to execute many different functions, such as calculation, pulling data from forms, special graphical effects, customized selections, custom security protocol and password systems, and much more.  Here are some essential points to keep in mind:

·         Java vs. JavaScript – These two languages are not the same.  Java uses completely separate files for their headers and classes, and they need compilation prior to execution.  Java is used in the creation of applets for pages.  JavaScript is much easier and simpler to learn than regular Java, and Java Script tutorials are often significantly more accessible for the average user.

·         OOP – OOP, or object oriented programming, is a specific programming technique that simplifies complicated computer programming conceptual issues.  Essentially, it lets a programmer treat whole chunks of data (defined either by users, or by the system itself), and modify or access them in specific ways.  It does this by classifying different parts of the programming into Objects, Methods, and Properties, which will be discussed more in depth in the future, in other Java Script Tutorials.

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. 

Java still has its place in the world of software development, but is it quickly becoming obsolete by the more dynamically enabled Python programming language? The issue is hotly contested by both sides of the debate. Java experts point out that Java is still being developed with more programmer friendly updates. Python users swear that Java can take up to ten times longer to develop. Managers that need to make the best decision for a company need concrete information so that an informed and rational decision can be made.

First, Java is a static typed language while Python is dynamically typed. Static typed languages require that each variable name must be tied to both a type and an object. Dynamically typed languages only require that a variable name only gets bound to an object. Immediately, this puts Python ahead of the game in terms of productivity since a static typed language requires several elements and can make errors in coding more likely.

Python uses a concise language while Java uses verbose language. Concise language, as the name suggests, gets straight to the point without extra words. Removing additional syntax can greatly reduce the amount of time required to program.  A simple call in Java, such as the ever notorious "Hello, World" requires three several lines of coding while Python requires a single sentence. Java requires the use of checked exceptions. If the exceptions are not caught or thrown out then the code fails to compile. In terms of language, Python certainly has surpassed Java in terms of brevity.

Additionally, while Java's string handling capabilities have improved they haven't yet matched the sophistication of Python's. Web applications rely upon fast load times and extraneous code can increase user wait time. Python optimizes code in ways that Java doesn't, and this can make Python a more efficient language. However, Java does run faster than Python and this can be a significant advantage for programmers using Java. When you factor in the need for a compiler for Java applications the speed factor cancels itself out leaving Python and Java at an impasse.

While a programmer will continue to argue for the language that makes it easiest based on the programmer's current level of knowledge, new software compiled with Python takes less time and provides a simplified coding language that reduces the chance for errors. When things go right, Java works well and there are no problems. However, when errors get introduced into the code, it can become extremely time consuming to locate and correct those errors. Python generally uses less code to begin with and makes it easier and more efficient to work with.

Ultimately, both languages have their own strengths and weaknesses. For creating simple applications, Python provides a simpler and more effective application. Larger applications can benefit from Java and the verbosity of the code actually makes it more compatible with future versions. Python code has been known to break with new releases. Ultimately, Python works best as a type of connecting language to conduct quick and dirty work that would be too intensive when using Java alone. In this sense, Java is a low-level implementation language. While both languages are continuing to develop, it's unlikely that one language will surpass the other for all programming needs in the near future.

Tech Life in New York

City The Big Apple is home of two of the world’s largest stock market exchanges, the New York Stock Exchange and NASDAQ. As a leading business center in the United States, New York has more Fortune 500 headquartered companies than any other city. Technology is blossoming in the Big Apple as major internet conglomerates like Google move their offices into “telecom hotels” such as the 311,000 square feet office space downtown. As in any other city there are pros and cons of living in New York City. For instance, there is so much to do, it’s easy to get around with the transit system, it’s safe, convenient, and has plenty of job opportunities. On the other hand, it can be overwhelmingly expensive, overcrowded, a bit impersonal and fast paced. New Yorkers enjoy Central Park, multi cultural activities and food, theatre, film festivals, farmers markets, fashion and anything else they could possibly think of...it’s all there.
