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:

I’ve been a technical recruiter for several years, let’s just say a long time.  I’ll never forget how my first deal went bad and the lesson I learned from that experience.  I was new to recruiting but had been a very good sales person in my previous position. I was about to place my first contractor on an assignment.  I thought everything was fine.  I nurtured and guided my candidate through the interview process with constant communication throughout.  The candidate was very responsive throughout the process.  From my initial contact with him, to the phone interview all went well and now he was completing his onsite interview with the hiring manager. 

Shortly thereafter, I received the call from the hiring manager that my candidate was the chosen one for the contract position, I was thrilled.  All my hard work had paid off.  I was going to be a success at this new game!  The entire office was thrilled for me, including my co-workers and my bosses.  I made a good win-win deal.  It was good pay for my candidate and a good margin for my recruiting firm. Everyone was happy. 

I left a voicemail message for my candidate so I could deliver the good news. He had agreed to call me immediately after the interview so I could get his assessment of how well it went.  Although, I heard from the hiring manager, there was no word from him.  While waiting for his call back, I received a call from a Mercedes dealership to verify his employment for a car he was trying to lease. Technically he wasn’t working for us as he had not signed the contract yet…. nor, had he discussed this topic with me.   I told the Mercedes office that I would get back to them.  Still not having heard back from the candidate, I left him another message and mentioned the call I just received.  Eventually he called back.  He wanted more money. 

I told him that would be impossible as he and I had previously agreed on his hourly rate and it was fine with him.  I asked him what had changed since that agreement.  He said he made had made much more money in doing the same thing when he lived in California.  I reminded him this is a less costly marketplace than where he was living in California.  I told him if he signed the deal I would be able to call the car dealership back and confirm that he was employed with us.  He agreed to sign the deal. 

Toshiba has released a new line of solid-state drives (SSD) using 19 nanometers, which is currently the industry’s smallest lithography process.

 

The lineup will include mini-SATA and 2.5-inch form factors along with drives in 7mm and 9.5mm heights. All drives will use the most current serial ATA 6Gbps interface protocol.

 

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 */

Tech Life in Indiana

Some fun facts about Indiana: The first professional baseball game was played in Fort Wayne on May 4, 1871; The Indiana Gazette Indiana's first newspaper was published in Vincennes in 1804; A great deal of the building limestone used in the U.S. is quarried in Indiana. As for the tech life in Indiana, there are growing opportunities within the state in some of the major corporations such as WellPoint, Biomet, and Zimmer Holdings (just to name a few)

training details locations, tags and why hsg

A successful career as a software developer or other IT professional requires a solid understanding of software development processes, design patterns, enterprise application architectures, web services, security, networking and much more. The progression from novice to expert can be a daunting endeavor; this is especially true when traversing the learning curve without expert guidance. A common experience is that too much time and money is wasted on a career plan or application due to misinformation.

The Hartmann Software Group understands these issues and addresses them and others during any training engagement. Although no IT educational institution can guarantee career or application development success, HSG can get you closer to your goals at a far faster rate than self paced learning and, arguably, than the competition. Here are the reasons why we are so successful at teaching:

  • Learn from the experts.
