Java is the technology of choice for high-end enterprise applications. The most common applications that developers are involved with are JavaServer Pages web applications, also known as JSP applications. JSP has become one of the two standards for developing high traffic web applicati...
When Sun’s developers created Java, they tried to keep the syntax for Java similar to the syntax for C++ so it would be easy for C++ programmers to learn Java. In addition, they designed Java so its applications can be run on any computer platform. In contrast, C++ needs to have a spec...
You bought a static rule-based correlation and you want to get the most out of it, or are you planning on getting and deploying one? There are some simple steps you can take to maximize its efficiency. The main use case for correlation is real-time incident management, so you need a 2...
As you start to scale a software development process it becomes apparent that code and user stories have to be merged more frequently. Sometimes changes may flow from one organization to another. This means that you will need to take code from one team, merge, integrate and test those ...
Whether ‘tis nobler in the mind to suffer the slings and arrows of your IT manager or to take up cache against a sea of data.  With apologies to Bill Shakespeare, the IT Dog is discussing two different cache write policies: write through and write back.  Let me take a r...

Each application developer faces the problem of logging usage information. On the one hand, the more logging that’s done the easier it is to detect and locate the source of problems. On the other hand, large volume logging might impair an application’s performance. This problem is typ...
Compounding the combinatory explosion in the number of static-based correlation rules, it is impossible to correlate 100% of all your logs, it is just too expensive and not practical. Read on... A correlation engine works really hard, even when dealing with a limited set of scenarios:...
If you want a well rounded introduction to JAVA 7, look no further. This book touches on all the things you would expect in an introduction to a programming languages. The book is broken down into six parts and a set of appendices. I have listed the chapters by part below. Part I: ...
Today’s web sites are often cluttered up with third-party content that slows down page load and rendering times, hampering user experience. In my first blog post, I discussed how third-party content impacts your website’s performance and identified common problems with its integration....
Data integration is a complex, detailed, sometimes excruciating boring activity, that is not an activity for the light at heart. This book does a great job of digging into the details of the data transformations. It is not just a high level look at data integration, it gets into the ...
All in all I highly recommend this book to every Java programmer. I really like the CERT books. This one is no different, however, it is not one to read from cover to cover, at least not for me. It contains a catalog of rules for programming secure java code. What I have been doing is...
In early JVM releases, it was common to delegate Java monitor operations directly to operating system monitors, or mutex primitives. As a result, a Java application experiencing lock contention would exhibit high values of system CPU utilization since operating system mutex primitives ...
If we search for MVC frameworks we found many variants: MVC1, MVC2, MVC3, MVP, MVVM and PureMVC. Let's discover the main difference between PureMVC and the other variants. According to the MVC definition from wikipedia: "Model View Controller (MVC) pattern creates applications that ...
All in all I highly recommend this book as a learning resource for Java.  It covers a ton of topics and covers them in detail with plenty of examples.  I would expect to find this in any good Java programmer's library. I have had several Deitel books in the past and I would say my big...
Like evolution, constant technological change is unstoppable, whether through improvements or the emergence of entirely new technologies. This is especially true in the hosting industry where a new generation of more flexible and efficient platforms is emerging to take advantage of the...
Being new to Java I am interested in finding out the low-level nitty-gritty details of the Java HotSpot VM. This book was definitely the right choice for that. I must admit being a veteran .NET developer helped when digging into the different concepts and there are a ton of them. One ...
JRE 6 was released in 2006, five years after a major JRE version was released. For the past few years Java was looking stagnant, and many Java developers began to worry; this concern was amplified when Oracle purchased Sun. We will try to discover if there's a big refactoring or maybe...
Most Java performance opportunities fall into one or more of the following categories: Using a more efficient algorithm. The largest gains in the performance of an application come from the use of a more efficient algorithm. The use of a more efficient algorithm allows an application ...
You don’t agree with that? Have you ever looked at the details of your page load time and analyzed what really impacts Page Load Time? Let me show you with a real life example and let me explain that in most cases you only control 1/3 of the time required to load a page as the rest is ...
The best thing about this book is that each subject is truly the actions and insights that give the most understanding with the least investment. I have been a fan of the Net Objectives books since the first edition of Design Patterns Explained: A New Perspective on Object-Oriented De...
