A Javascript When Function
function when(conditionFunc, execFunc, interval){ if (conditionFunc()){ execFunc(); }else{ setTimeout(function(){ when(conditionFunc, execFunc, interval);}, interval); } } You have some code which should only execute when a condition is true. E.g. You have code which relies on a javascript library but can't be sure the library has loaded yet and don't want the code to execute until it has. This is common if you have a bookmarklet which injects more than one <...

3 ways to remove duplicates in List
Frequently, we may have an ArrayList which stores many values, and we need to process the ArrayList and get what are the distinct values in the list, or we may want to count occurrence of each value in the ArrayList. We can remove the duplicates in a few ways. Here we propose 3 methods : public static void main(String[] args){ //SuperClass sub=new SubClass(); String[...
How Can Your Data Be Stolen Online?
In 2019, according to Statista, nearly 165 million sensitive records were exposed in the US due to data breaches. Unfortunately, data theft is not going anywhere. Hackers are using increasingly sophisticated methods to steal information, but thankfully there are measures you can take to ensure your data stays safe. Here are some of the most common ways people get their data stolen online and how you can take precautions against the methods cybercriminals use. Human Error Hacking is one of the m...

C++ Versus Objective-C
What will programming in Objective-C mean to the C++ programmer Different Object Oriented Languages Almost all of us have heard the term object oriented programming, and most of us have used C++. How will Apple's purchase of NeXT, and NeXT's framework using Objective-C affect us as we develop software? If we know C++ already, how hard will it be to get up to speed on Objective-C? Many people will agree that once they understand the concepts of object oriented programming it doesn't matter...

Strict mode in JavaScript
1. Introduction In addition to normal mode, ECMAScript 5 includes the other mode : strict mode. It means it will make JavaScript codes execute in a more strict environment. The purposes to have strict mode are: Remove some unreasonable and parts of JavaScript syntax. Reduce some of the quirk behaviors. Remove some insecure parts of code execution. Make the execution environment more secure Improve interpret efficiency and increase the execution speed Build foundation for future JavaScript versi...

Why I left Google
Ok, I relent. Everyone wants to know why I left and answering individually isn’t scaling so here it is, laid out in its long form. Read a little (I get to the punch line in the 3rd paragraph) or read it all. But a warning in advance: there is no drama here, no tell-all, no former colleagues bashed and nothing more than you couldn’t already surmise from what’s happening in the press these days surrounding Google and its attitudes toward user privacy and software develo...

Game Development Essentials #1 - Don’t use inheritance for your game objects
I recently released my first game, X Fleet, available now in Android Market. It’s a fast paced space shooter / rpg riddled with awesomeness and you should get it now. The reason you should avoid hierarchies/inheritance is your objects will be far too varied and complicated in form to be accurately represented as such. More on this below. The alternative is a component model. This is very basic. Instead of having everything inheriting (e.g. Object -> MovableObject -> Animat...

Dates in PHP and MySQL
I see a lot of people on forums and on my training courses asking about the best way (or any way) to manage dates stored in a MySQL database and used in PHP. Three options follow, but first the problem.PHP uses unix timestamps for all its date functionality. It has methods to convert these timestamps into pretty much any text format you could want but internally it uses the timestamp format. A timestamp is simply an integer. Specifically, it’s the number of seconds that have ela...

Prototypes and Object Orientation
David Chisnall takes a look at the two dominant paradigms in object-oriented languages (classes and prototypes) and discusses the strengths and weaknesses of each.Two terms are quite often confused when describing programming languages:class-based and object-oriented:Simula was the first class-based language. It provided classes (actually implemented using closures) as a means of encapsulating abstract data types.Smalltalk was the first object-oriented language. It provided a...
