A Deep Dive into the Core Metrics of the Java Virtual Machine
By Eugen Paraschiv
Overview of JVM Metrics
In this article, we'll cover how you can monitor an application that runs on
the Java Virtual Machine by going over some of the critical metrics you need
to track. And, as a monitoring tool, we'll use Stackify Retrace, a full APM
solution.
The application we'll monitor to exemplify these metrics is a real-world Java
web application built using the Spring framework. Users can register, login,
connect their Reddit account and schedule their posts to Reddit.
How JVM Memory Works
There are two important types of JVM memory to watch: heap and non-heap
memory, each of these with its own purpose.
The heap memory is where the JVM stores runtime data represented by allocated
instances. This is where memory for new objects comes from, and is released
when the Garbage Colle... (more)

22nd International Cloud Expo, taking place June 5-7, 2018, at the Javits
Center in New York City, NY, is co-located with the 1st DXWorld Expo and will
feature technical sessions from a rock star conference faculty and the
leading industry players in the world. Cloud computing is now being embraced
by a majority of enterprises of all sizes.
Yesterday's debate about public vs. private has transformed into the reality
of hybrid cloud: a recent survey shows that 74% of enterprises have a hybrid
cloud strategy. Meanwhile, 94% of enterprises are using some form of XaaS -
software, platform, and infrastructure as a service.
Digital transformation is changing the face of business. The IDC predicts
that enterprises will commit to a massive new scale of digital
transformation, to stake out leadership positions in the "digital
transformation economy."

OOP Concepts for Beginners: What Is Polymorphism
By Thorben Janssen
The word polymorphism is used in various contexts and describes situations in
which something occurs in several different forms. In computer science, it
describes the concept that objects of different types can be accessed through
the same interface. Each type can provide its own, independent implementation
of this interface. It is one of the core concepts of object-oriented
programming (OOP).
If you're wondering if an object is polymorphic, you can perform a simple
test. If the object successfully passes multiple is-a or instanceof tests,
it's polymorphic. As I've described in my post about inheritance, all Java
classes extend the class Object. Due to this, all objects in Java are
polymorphic because they pass at least two instanceof checks.
Different types of polymorphism
Java supports two types of... (more)
CloudExpo | DXWorldEXPO have announced the conference tracks for Cloud Expo
2018, introducing DXWorldEXPO.
DXWordEXPO, colocated with Cloud Expo will be held June 5-7, 2018, at the
Javits Center in New York City, and November 6-8, 2018, at the Santa Clara
Convention Center, Santa Clara, CA.
Digital Transformation (DX) is a major focus with the introduction of DXWorld
Expo within the program. Successful transformation requires a laser focus on
being data-driven and on using all the tools available that enable
transformation if they plan to survive over the long term.
A total of 88% of Fortune 500 companies from a generation ago are now out of
business. Only 12% still survive. Similar percentages are found throughout
enterprises of all sizes.

I love it when I get feedback from a blog that I’ve written. I appreciate
the different perspectives and insights that others bring to a topic of
interest. And no blog that I’ve written has drawn more comments than my
blog, “Isaac Asimov: The 4th Law of Robotics.”
The section of the blog that fueled the most comments stem from a scene in
the movie I, Robot where Detective Spooner (played by Will Smith) is
explaining to Doctor Calvin (who is responsible for giving robots human-like
behaviors) why he distrusts and hates robots. He is describing an incident
where his police car crashed into another car and both cars were thrown into
a cold and deep river – certain death for all occupants. However, a robot
jumps into the water and decides to save Detective Spooner over a 10-year old
girl (Sarah) who was in the other car. Here is the dialogue between Detective
