Java Polymorphism and Overriding Methods
Most Java developers will be familiar with polymorphism – we’ve all seen the example of the Dog and Cat classes inheriting from some abstract Animal class and having their say() methods produce different results. But it’s still worthwhile to look at a few simple examples to reinforce the concepts.First, we define a simple class with one instance method and one static method.public class A { public String getName() { return "I a...

That “JavaScript not available†case
During some interesting discussions on Twitter yesterday I found that there is now more than ever a confusion about JavaScript dependence in web applications and web sites. This is a never ending story but it seems to me to flare up ever time our browsing technology leaps forward. I encountered this for the first time back in the days of DHTML. We pushed browsers to their limits with our lovely animated menus and 3D logos (something we of course learned not to do again, right?) and we were ...

JavaScript to open link in new window without being popup blocked
To ensure security and reduce spamming, modern browsers have implemented very strict rules on when a new window can be opened in a web page. Currently browsers restrict that any new web page to be opened in a new window must be initiated with an user action. The action is usually an user click event. Otherwise, a popup blocker would show on the browser address bar which indicates that something is blocked. To workaround this issue, normally you should implement the window open logic in a click e...

String.length() vs String.getBytes().length in Java
In Java, String.length() is to return the number of characters in the string, while String.getBytes().length is to return the number of bytes to represent the string with the specified encoding. By default, the encoding will be the value of system property file.encoding, the encoding name can be set manually as well by calling System.setProperty("file.encoding", "XXX"). For example, UTF-8, Cp1252. In many cases, String.length() will return the same value as String.getBytes().length, but in some ...

Proximity Cards Do More Than Just Open Doors
Credit: Susanne Plank via Pexels Locksmiths from centuries ago couldn’t have possibly imagined opening a door by tapping a card roughly the size of a credit card. Back then, security depended on physical locks, not sealed antennas made from coiled wire, integrated circuits, and capacitors. Today, proximity cards are a popular form of keycard used in hotels, government buildings, healthcare facilities, and many more places. They open doors for people with authorized access, but they also d...
A return to good code
Stop doing this:public boolean foo() { if (true) { return true; } else { return false; }}It always amazes me when I dig into an open source project, and I see code written by supposed experts, and reviewed by seasoned professionals, and nobody slaps the wrists of the developer who shoves return statements right in the middle of a method.Tell me, how hard is it to do this:public boolean foo() { boolean flag = true; ...
Web Security: In-Depth Explanation of X-XSS-Protection
What is X-XSS-Protection X-XSS-Protection is an HTTP response header designed to enable or configure built-in cross-site scripting (XSS) filters in certain versions of Internet Explorer, Chrome, and Safari. The purpose of these filters is to detect reflected XSS attacks in the response and prevent the loading of pages, thereby protecting users from such attacks. The X-XSS-Protection response header was initially introduced by Microsoft in Internet Explorer 8 to control the browser's XSS filter. ...

10 reasons why Dart is cooler than JavaScript
Dart is a new programming language from Google and after coding JavaScript for over one year now, I immediately felt in love with it. Coming from the Java world I had a good bunch of things I had to learn before I could use JavaScript. Some people say, you need to dig deep into JavaScript, otherwise you are not allowed to speak about the pros and cons of a language. I am not a JavaScript Ninja. But I strongly believe a programming language should be easy to learn, easy to understand and s...

A completely new approach to surveillance - should you be worried?
Paranoia is not necessarily a bad thing - assuming someone is really out there to get you. True or not, the paranoid have had issues they need to control explode as the internet developed, they also got specific tools to make their secrets (or their life, not everybody has a dark secret) more secure and under control. Unfortunately to them, and to the amazement of science and science fiction fans worldwide, a new way of obtaining secrets has appeared and it’s something very few expected. ...
