Here’s  is a quote from the About page of the Web site ehow.com: “eHow is your one-stop online resource for life’s challenges. Professionals in every field come together to offer expert advice, backed by the additional support of a can-do eHow community.“ Experts are also human beings and sometimes they make mistakes too. But when I’ve read the following article I was stunned: Guys and girls, I’m not an eHow-grade expert, but I’ve been doing both Java and JavaScript for while. Trust me, the above description is absolutely wrong! Please ignore. Also, if you know any of the 35 people who found this helpful, get in touch with them and tell them the truth! There is well known statement that “Java is to JavaScript as ham is to hamster”. So I’m looking forward to a new article at eHow that will be a creative interpretation of the Wikipedia definition: “Hamster, aslo known... (more)

GlassFish, Open MQ, and the Ear-Eye Problem By @YFain

GlassFish, Open MQ, and the Ear-Eye Problem Yesterday I’ve been updating code examples for the messaging chapter for the 2nd edition of my Java book. While doing this, I ran into an issue, then fixed it, but the cause and the solution illustrate the situation that we call “Ear-Eye”, which comes from and old joke popular in the USSR, where TV propaganda was stating that everything is great while people had hard time finding food in store. Here’s the joke: An old lady comes to a medical center saying that she needs to see an Ear-Eye specialist. The receptionist replied, “There is n... (more)

JavaFX Event Handling and Property Binding

Some time ago I blogged that Java Swing should be deprecated and replaced with JavaFX. In this blog I’ll show a piece of JavaFX namely event handlers and binding. I’ve created a simple Sign In window with a GridPane layout (it’s JavaFX equivalent of Swing’s GridBagLayout). I’m not going to spend much time on the GridPane itself, but will show you a basic event handling and a binding. In JavaFX an event object is represented by the instance of the class javafx.event.Event. There are different ways of handling events. Depending on how you structured your application you can handle... (more)

Yakov Fain's (@yfain) Blood Pressure At @ThingsExpo

Blood Pressure While Presenting at Conferences In June I was presenting at the Internet of @ThingsExpo at the Javits Center in New York City. During my talk I was demonstrating how to integrate consumer devices into a business workflow. In particular, I was doing live measuring of my own blood pressure to show how to integrate consumer devices into a business workflow. Internet of Things, you know. The results were automatically appearing in my customized Web application. When the results appeared on my mobile device I was quite surprised to see that my pressure was 200/120. This... (more)

Working on the Java Tutorial, Second Edition

In 2011 Wiley (Wrox) published my book “Java Programming. 24-Hour Trainer“. To be honest, I don’t like the title because it misleads people as if this book promises that the reader can learn Java within 24 hours. But creators of this series (many titles were published under this umbrella) meant to say that this book was like your personal instructor; 24 hours a day. Whatever. It’s not my call. But earlier this year I got a call from the publisher stating that they’re happy with the book sale numbers and want me to update the book and release the second edition reflecting the lat... (more)
