Best Compilers/Interpreters to Practise Programming Online

There are numerous programming languages available these days for developers and every language comes with some amazing features and supported tools to suit various programming needs. Many of these programming languages are either compiler based or interpreter based, so programmers would require a Compiler or an Interpreter software to execute and test the codes.

Most programmers use an offline compiler program to support their programming needs, but there also many online compilers and interpreters available which coders can utilize. An online compiler helps a programmer write and test his codes online without the need to install any software on his/her system. Online compilers and interpreters are also better since they are mostly cloud based and help improve the productivity of a programmer.

Below we are mentioning some of the most popular online compilers and interpreters available where a programmer can learn and practise programming.

Guide to learn Cloud Computing

Nowadays we often hear the term cloud computing. While most us vaguely know that it something about storing our data on a common storage and have access to it from anywhere irrespective of the device we are using, that is entirely not true.

This article gives a lowdown about what exactly is cloud computing and how to begin learning it? The word ‘Cloud’ is used a metaphor to “The Internet”. So cloud computing means a type of “Internet-based computing”.

What is Cloud Computing defines cloud computing as “a type of computing that relies on sharing computing resources, having different services delivered to an organisation’s computers and devices through the Internet rather than having local servers or personal devices to handle applications.”

In order to do this, cloud computing uses networks of large groups of servers linked together to divide the data-processing jobs across them. Often, visualization techniques are used to maximize the power of cloud computing.

The goal of cloud computing is to apply high performance computing power in consumer oriented applications in order to save time and financial resources to purchase, deploy and maintain an infrastructure

Cloud Computing Tutorial for Beginners

So what are the pre-requisites to learn it? Well you don’t really have to know coding or have any experience in the IT world. Other than having some basic knowledge of Computers, Internet, and Database, theoretically anyone can learn Cloud Computing.

This quick reference guide helps understand the basics of cloud computing model, the architecture and infrastructure. This also gives a brief overview about the deployment and service models.

W3C launches HTML5 MOOC course on edX

The World Wide Web Consortium (W3C) which is the main international standards organization for the Web has recently joined the edX platform. W3C has been instrumental in developing and hosting open-source tools that are used every day by millions of Web developers.


The first course of W3C on edX, HTML5 Part 1, taught by University Côte d’Azur professor Michael Buffa, is 6 weeks long starting June 1st and is now open for enrollment. This HTML5 MOOC course will give students an opportunity to learn the new features introduced, directly from the experts who helped create HTML5.It covers how to:

  • Learn the new simplified HTML5 tags, and how to use micro data
  • Play with the audio and video tags, draw and animate fun Web graphics.
  • Practice coding techniques thanks to multiple interactive examples and many more.

HTML5 which is the standard language of the Web was developed by W3C and will continue to be the essential technology for organizations delivering applications across multiple platforms.

As such, HTML5 is now supported on mobile phones, connected objects, game consoles, automobile dashboards, and devices that haven’t even been considered yet. Write once and deploy anywhere! Additionally this tutorial on HTML also teaches you everything about the basics.
