Java Memory Management
[Aug, 28, 2012]    |
   Tags:

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 */
Security Risks That Small Businesses Should Know About
[Mar, 13, 2019]    |
   Tags:

 
One of the biggest threats facing small businesses right now is cyber security. Hackers have figured out that small business don’t have robust systems; therefore, they are easy for the picking. If you are a small business owner, you know how limited your resources are. As such, every dollar counts. Therefore, you can’t afford to lose customers, deal with lawsuits caused by data breaches or pay IT help staff to try to fix the issue. Below are some of the IT risks faced by your business and potential consequences. Try your best avoid them at all costs. 
 
1. Phishing 
 
This is perhaps one of the easiest ways to detect if a hacker is trying to get into your system. If you happen to receive an email that claims to be from a financial institution and asks you to provide certain data, ignore it. In fact, delete it. This is because once you make the mistake of opening such a mail or clicking the link provided, you provide a gateway for hackers to penetrate your system and steal information. For this reason, it's vital that all employees  are aware of such emails and delete them without clicking on any links.
 
2. Passwords 
 
Another way that hackers can attack a small business is by cracking system passwords. If the hackers manage to crack the password of even a single employee, they can use that person’s account to gain unrestricted access to confidential company records. Therefore, tell your workers that they should never forgo strong password creation procedures. They should take their time to create a password that can’t be easily cracked. 
 
3. Vulnerable Devices 
 
In your small business, you probably use printers, routers, and other electronic hardware to execute office tasks. Most of the time, such pieces of hardware are connected to your firm’s network. If you have not updated the software on these machines, hackers can use them to gain access to your network and steal invaluable information. Therefore, make sure that you install patches in all electronic devices connected to your network. 
 
4. Lack of Data Encryption 
 
In the modern age, you can send information through various electronic devices. Some of those machines can have inbuilt security features to protect the data while others may not have. Data from the vulnerable devices can be easily intercepted by hackers. If the information is your password, your network is no longer safe. To counter such interceptions, always encrypt your data before your send it. 
 
5. Seemingly Misplaced USB Drives 
 
Some hackers will infect a USB drive with malware and then drop it outside your offices. An unknowing worker may pick up the drive and use it on a company computer. Immediately the drive is plugged in, it releases the malware and creates a unique access point for the hacker, allowing them to steal information. To avoid such a scenario, warn your employees against using any USB drives without a proper source. 
 
 
Managing a small business means that you’re a lean, mean business machine. Often, it’s just you and a few trusted staff members. This is the reason, business owners need to have solid knowledge of where and how most important data is held. Whether it’s on site, in traditional desktops and servers, or in cloud services or mobile devices including those "BYOD" devices of your employees, in order to avoid risks, always pay attention to your enviroment. It's important to make sure that you regularly update your system, train your employees, update software and fix bugs. Often, many IT issues are caused by the smallest, almost unapparent mistakes that will affect how a program runs or a web page looks. You might not see IT as your highest priority, but in the right hands, it can become your most powerful tool for growth. 
The Value of Employee Training and Career Development
[May, 26, 2017]    |
   Tags:

We are not all equally motivated. Some people have more self-drive than other people. This is why we find that some people always end up at the top even when the odds are against them. An employee, with this realization, through the Human Resource department, should be able to design efficient career development systems. For this system to work, the employer must understand the nature of the business environment in which they are operating.

Why Train Employees?

The purpose of training employees is to enable them to grow with time and increase their efficiency. The business world is quite dynamic, nothing stays the same for long. Training one’s employees allows them to keep abreast with the ever changing technological advancements and many other factors that are relevant to his/her line of work. Employees cannot be expected to solve all their employer’s expectations with static skills and techniques. Even the most updated technology becomes obsolete at some point.
People are the biggest assets in organizations. For an establishment to flourish, it is important that the employer understands certain key things that help spur their development.

In a report from the Harvard Business Review, “The Impact of Employee Engagement of Performance,” the most impactful employee drivers are:

Cloud Computing: What It Means and How It Could Threaten the Traditional Outsourcing Model
[Apr, 25, 2014]    |
   Tags:

Cloud computing is the recent rage in the IT industry. According to the report by Forbes, the estimated global market for cloud computing is expected to reach $35.6 billion in 2015, from the $12.1 billion market of 2010.

How it began

The idea of cloud computing was inspired by the concept of “utility computing” which introduced the idea of computing using the virtual servers. These virtual servers do not actually exist anywhere physically and can be moved anywhere without causing any disturbance to the end users. Thus it minimizes the cost involved on the devices to a great extent and provides innumerable benefits to the companies that adopt this system.
