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)

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)

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)

Partying with IntelliJ IDEA Dart, Java, WebSocket and Glassfish

Recently I wrote a blog showing how to use the WebSocket protocol to push the data from a Java server to a JavaScript client. This time I’ll keep the same code on the server, but the client will be written in Dart. For this example I was using GlassFish 4.1 server, and IntelliJ IDEA 14.1 with installed Dart plugin. I also have Dart 1.9.1 SDK. My goal was to create one Web application deployable module that would contain both Java and Dart code. I’ll be brief assuming the the reader has some familiarity with IntelliJ IDEA IDE and the structure of Dart projects. Repeating the same e... (more)

How to create a signup screen to minimize the number of users who will sign up

I’m wondering if these developers do this on purpose or they are just random people in our profession? I was trying to sign up at this Web site. Had to enter my email and pick a password, which I did. Nobody warned me that the password had to be 8 characters until I pressed the submit button. Then the new window popped up: Just take a look and try to recreate the line of thinking of the developer of this piece of art: “I need to let the user enter the password that’s at least 8 characters long. So I’ll hide in the bushes and will quietly wait till the user will make a mistake ... (more)
