Algorithms #1 : Getting started.

What is an algorithm?

An algorithm is a procedure to accomplish a specific task in a finite number of steps. An algorithm is the idea behind any reasonable computer program.

To be interesting, an algorithm must solve a general, well-specified problem.

After all, everything in this world follows a procedure and algorithms literally shape the world around us. So, studying algorithms, I believe, is important for everybody. Computer algorithms are very interesting and enable us to solve huge number of problems with computer programs with least complexity. I personally feel that many of these algorithms like the divide and conquer algorithm are very much applicable in many real life situations as well. So, I thought we'll get started with learning about new algorithms (one every day if possible).

This is a video from TEDed that gives you an idea of what an algorithm is in its simplest sense. So, what are you waiting for? Lets jump right in!

A course in machine learning : BOOK

Machine learning is a powerful tool that is changing the computing world for good. So, what is all about this recent buzz word? I'll tell you.

Making machines learn

This is what the book on collective intelligence says: Machine learning is a subfield of artificial intelligence (AI) concerned with algorithms that allow computers to learn. What this means, in most cases, is that an algorithm is given a set of data and

The future of search

While skimming through business magazines, I recently read this article on how Google will change the world, again. Google gets down to doing what it knows best - developing new tech - to change your life. I thought it was worth sharing and here it is.

7 little known but super useful PHP functions

PHP have lots of built-in functions, and most developers know many of them. But a few functions are not very well known, but are super useful. This is an article from catswhocode.com explaining some of those functions that you can make use of.

Lets build software! Online MOOC courses to get you started.

Hello people! So, you want to build software? Here are some really awesome MOOC courses you might want to try. These courses are offered by Udacity.com and the best thing about these are that there are no deadlines. You get to learn at your own pace and earn a certificate of completion.

Kick Start to Programming Introduction to Computer Science and Building a search Engine
In this course you will learn key concepts in computer science and learn how to write your own computer programs in the context of building a web crawler.

Get, set, JAVA! Introduction to Programming with JAVA

In this class, you will learn basic skills and concepts of computer programming in an object-oriented approach using Java.

You will learn concepts like classes, methods and argument passing, loops, and general problem solving ability that will become building blocks to your programming skills.

What is a good design? Design Of Computer Programs

Learn new concepts, patterns, and methods that will expand your programming abilities, helping move you from a novice to an expert programmer.

Finding the Bugs. Software Testing

When writing software, destruction can be just as valuable as creation. Learn how to catch bugs and break software as you discover different testing methods that will help you build better software.

Taking down the Bugs! Software Debugging

In this class you will learn how to debug programs systematically, how to automate the debugging process and build several automated debugging tools in Python.

So, what are you waiting for? Lets get down there and build awesome software!

Spell Check in HTML

A lot of people are unaware of the spell check option that basic HTML offers. It can be implemented with a very small spellcheck attribute as shown below:
