  C++, Ruby and CoffeeScript complexity comparison

There are many programming languages around the world, they all designed to help programmer solve some problems, finish some tasks. These languages are often divided into different types, there are structural, object-oriented, functional, scripting languages etc. Some are easy to pick up such as Java, while some are thought to be difficult to learn such as C++. So how do we understand complexities of different programming languages?Many people agree that C++ is very complex languages, it has poi...

  The Wasteful Legacy of Programming as Language

A few years ago I visited a friend who is a graduate student in linguistics. After some time he asked me if I was aware of the work by Chomsky on formal languages. I told him that yes, Chomsky work was a basis for much of the developments in theoretical computer science. More than that, I was glad to learn that there was something technical that I could share and discuss with other people in linguistics. At the time I found this was just a great coincidence. It was only recently, though, t...

  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 <...

  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. ...

  Is Java Set ordered or not?

“Is Java Set ordered or not? ” is the most popular question asked when you interview for a Java Developer position. Many fail to answer it, and I have to admit I was one of the many. I have known the answer is “Yes and No” for a long time. No. HashSet is not ordered. Yes.TreeSet is ordered. If the interviewer continues with some follow up questions, I’m not confident that I know the answer then. Why is TreeSet ordered? Are there any other ordered S...

  What Happened to Software Engineering?

Over the past few years there has been an evolutionary shift in the world of software development.  Not very long ago, the dominant Software Development Life Cycle (SDLC) methodology was the Waterfall Method with very specific phases that separated the construction phase from phases like design and test. The software development industry, still very new, was striving to find a repeatable, predictable process for developing software.  The best model for this seemed to be the physical sc...

  In defence of Objective-C

An unashamed apologist’s perspective on the loveliest language i’ve worked with.I’ve worked with a lot of programming languages in my time. Not a huge number, mind you, but enough that i can say that i’m open minded and seasoned about it. And, as they say: ‘Don’t feed the trolls’ – well, i’m about to do exactly that: feed the trolls at work who love to rag on about how awful obj-c is! So here i go, foolishly treading where no sensible...

  Name resolution order in JavaScript

To understand what value a variable has in JavaScript, we need to understand some concepts such as scope and name resolution order. JavaScript has two scopes; one is program level and the other one is function level. Unlike in C,C++ or Java, JavaScript has no block level scope. So a variable defined in a if block will still be available outside. For example, the below example: var foo = 1; function bar() { if (true) { var foo = 10; } alert(foo); } bar(); The alert will display 10 since the ...

  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[...

  Java’s toLowerCase() has got a surprise for you!

Have you ever encountered a surprise while using toLowerCase()? This is a widely used method when it comes to strings and case conversion. There is a nice little thing you should be aware of. toLowerCase() respects internationalization (i18n). It performs the case conversion with respect to your Locale. When you call toLowerCase(), internally toLowerCase(Locale.getDefault()) is getting called. It is locale sensitive and you should not write a logic around it interpreting loca...
