Why I Rejected a LinkedIn-Originated Offer of 10 Million Euros LinkedIn is a popular social network for connecting professionals, and I have an account there. Every day I get an invite to connect with someone. Typically I ignore these invites unless I know the person. But I’ve never received invites to connect from a chair of board of directors of a bank. Till yesterday.  So I’ve accepted the invite. Then I’ve received an LinkedIn email from this woman stating that she had a business proposition for me, and if I was interested, she was ready to explain. She also provided her email that ended in outlook.com. I checked her LinkedIn profile again. Looked legit. She even had a Twitter account with recent tweets in two languages. I responded that I was ready to hear about this business proposition. Next day I’ve received a long email from her explaining how she had a priv... (more)

Am I Still a Java Developer? By @YFain | @ThingsExpo [#IoT]

This morning I got the following email from a Java developer: “It seems you are doing less Java and more web development every year.” This got me thinking, and I decided to write this blog. Am I still a Java developer after 17 years of using this language? I certainly am. But in today’s world using just one programming language is almost impossible unless you’re willing to limit yourself to the server-side development. I’m not saying this is bad – it’s a huge field for never ending self-education and research. Even from the career perspective becoming an expert in a specific Jav... (more)

Containers and AngularJS for Java Developers By @YFain | @DevOpsSummit [#DevOps]

Introducing AngularJS to Java Developers If you want to develop Web applications, you’ll need to learn JavaScript. But writing code in JavaScript (at least in its ECMAScript 5 incarnation) is non-productive. You need to pick up a one of the JavaScript frameworks, because: they make you more productive will deal with cross-browser compatibility and make the application more structured may include reusable components lower the amount of manually written code. JavaScript market offers multiple frameworks and libraries. While frameworks expect you to programs using well defined rules... (more)

Teaching Kids Programming: Even Younger Kids Can Learn Java

My solution to the problem? I've written my own e-book on it: Java Programming for Kids, Parents and Grandparents. Dave became my first kid student and this has helped me a lot to understand the mentality of the little people. This is what I've learned while working on this project: Most of the programming tasks require minimal knowledge of arithmetic and algebra skills. To start programming, a kid needs to understand what x = y+2 means. Another important concept to understand is an if statement.   Kids develop the abstract reasoning abilities by the fourth-fifth grade, and they... (more)

Pushing Data to Multiple WebSocket Clients From a Java Server By @YFain | @ThingsExpo [#IoT]

Pushing Data to Multiple WebSocket Clients From a Java Server Finished writing the WebSocket chapter for the second edition of my Java 24 Hour Trainer. In this blog I’ll show you one of the code samples from lesson 28. Pretty often you need to write a program that publishes the same message to all connected clients. For example, multiple clients of the online auctions have to be notified when a new bid is placed on the product. Another example is when a new stock price quote need to be pushed from the server to all connected clients. With websockets it’s a pretty easy task. I’ll... (more)
