PuneTech Video: Basics of REST

A few weeks ago, the TechNext group, which holds fortnightly talks on advanced tech topics in Pune had an event titled Indepth – RestFul Web Service, Cross Site Scripting and Web Security hacks. Vivek Shrinivasan and Meher Ranjan who attended the talk interviewed the speakers to get a quick overview of the talk.

The interview, where Loukik Purohit gives a basic overview of REST, has been put up on the PuneTech YouTube Channel:

You should see the video above, but if you don’t go to

Note: this is a very, very basic introduction to REST and should only be considered as an appetizer to get you interested in REST. There are major important aspects to REST that anyone who’s really interested in REST must understand, like server statelessness, hypermedia as the engine of state, which are not covered in this video.

Interested readers are encouraged to read Dhananjay Nene’s very long but excellent post “Why Rest”.

Call for Papers: ACM Pune’s Compute 2012 Conference on Intelligent & Scalable Systems

ACM Pune writes

With the advent of information age/knowledge age powered by internet, increasingly large amount of information is being generated and is becoming accessible electronically. The internet has promoted and sped the growth of information. It is growing at an astounding pace and today has more than 34 Billion web pages. It is now an ocean with various kinds of artifacts. However most of the information artifacts are designed and developed for consumption by humans.

High performance computing systems are employed across diverse fields to simulate and study complex systems, and generate new knowledge and information. Advances in field range from hardware and software architecture techniques to novel applications, and are increasing the pace of generation of new knowledge and information. An important concern is the scalability of these techniques. Cloud computing, for instance, holds a lot of promise in this direction.

Enterprise systems are growing in size, large software frameworks are being deployed. The dynamic business scenarios are prompting mergers and acquisitions due to which different IT systems are interfaced with each other. This is increasing the complexities of the systems and there is significant learning curve to understand such applications. Enterprises are facing problems related to comprehension, knowledge representation and reasoning. The 21st century needs systems that that are less people dependent, able to capture expert knowledge, and equipped to handle information overload.

Compute 2012 invites submissions from both researchers and practitioners in the broad area of scalable and intelligent systems. An indicative list of appropriate topics is as follows:

Phanindra Sama, CEO & Co-Founder to speak in Pune – 16 Sept is a truly Indian internet commerce success story. Nowhere else can I imagine a website that sells bus tickets being so successful. And, to be frank, when I first heard about redBus, I did not think much of its prospects myself. Hence I think it will be very interesting for the tech as well as the entrepreneur community in Pune to listen to the co-founder and CEO of on 16th September when he talks about his story so far, as part of TiE Pune’s excellent “My Story” series of talks.

A similar session, My Story by’s Mohit Dubey is one of my favorite tech events in Pune this year, and I loved the advice he gave. That is why I have high hopes from this event.

Here is TiE Pune’s description of this event:

“From a single idea to India’s largest bus ticketing company, redBus is an entrepreneurial success story with resonance around the world. It remains compelling proof that a young visionary with a strong engineering background can use technology and insight to create a competitive business and transform an industry.”
