Disclaimer : This article consist of my brutally honest review about Ruby Conf India 2015, If you are prone to depression, heart attack while reading criticism, please STOP reading this letter now  and move on. I know organizers worked hard to organize this event and I thank you for that but this does not mean I am happy with the way it was organised. I have complaints, so do lots of people I know. Someone has to raise voice, for now I am taking this responsibility. 1. Why Discriminate ? I was given accommodation in Justa-panjim while most of the conf attendees were in Cidade-goa, those two hotel are incomparable. Justa-panjim didn't have enough water for bathing, forget about swimming pool, beach. I didn't had complained if everyone was given accommodation in Justa-panjim, Yes I am being jealous here..!!! I paid conf fees(lite tickets.. yes thats how early I booked my ticket.) and I deserve to be treated equally , why discriminate ? 2. Where's Ruby ? In some o...

Loading Ember model in route is as simple as: App.PostsRoute = Ember.Route.extend({   model : function (params) {      return this .store.find( ' post ', params.post_id );   } }); But when loading model using findQuery then App.PostsRoute = Ember.Route.extend({   model :  function (params) {      return   this .store.find( ' person , {name: params.username} ).then(function(result){         return result.get('firstObject')      });   } }); findQuery return Array therefore select firstObject from Array, Remember to return Array from api for '/persons?name=test_name' url.

It was time for another Rails Rumble event, and I was looking for Ideas what to build.  Through one of coding competition I came across a problem in which you have to write a algorithm to outbid computer. I am (always been ) fan of Computer Games, so I thought why not build a Game based on this problem. Rails Rumble is a 48 hrs coding competition in which you have to build one Rails application. At this point, I knew what to build and which framework to use, but I didn't knew how to built it or even its possible in Rails, so I presented my Idea in Open Source Friday  .  I dry run my Idea on white board and played  a demo with Gautam Rege ( @ gautamrege ) on white board. People liked the Idea, and suggested how it can be done. Sanjiv Jha got interested in this game and joined me in the journey. The day of competition arrived 19 Oct 2013. Sanjiv and I coded 2 days , Stack used in Bidder is Ruby 2, Rails 4, Bootstrap 2.3, jquery 1.9, we used  ...
