Programming for the Web with Ruby

Registrations are now open for RubyLearning’s FREE, online course on “Programming for the Web with Ruby“. Web-based applications offer numerous advantages, such as instant access, automatic upgrades, and opportunities for collaboration on a massive scale. However, creating Web applications requires different approaches than traditional applications and involves the integration of numerous technologies. The course topics would hopefully help those that have some knowledge of Ruby programming to get started with web programming (this does not cover Ruby on Rails).

Who’s It For?

Anyone with some knowledge of Ruby programming.


The course starts on Monday, 20th Feb. 2012 and runs for 2 weeks.

RubyLearning’s IRC Channel

Most of the mentors and students hang out at RubyLearning’s IRC ( channel ( for both technical and non-technical discussions. Everyone benefits with the active discussions on Ruby with the mentors.

Here are some details on how the course works:


Once the course starts, you can login and start with the lessons any day and time and post your queries in the forum under the relevant lessons. Someone shall always be there to answer them. Just to set the expectations correctly, there is no real-time ‘webcasting’.

  • The Mentors shall give you URL’s of pages and sometimes some extra notes; you need to read through. Read the pre-class reading material at a convenient time of your choice – the dates mentioned are just for your guideline. While reading, please make a note of all your doubts, queries, questions, clarifications, comments about the lesson and after you have completed all the pages, post these on the forum under the relevant lesson. There could be some questions that relate to something that has not been mentioned or discussed by the mentors thus far; you could post the same too. Please remember that with every post, do mention the operating system of your computer.
  • The mentor shall highlight the important points that you need to remember for that day’s session.
  • There could be exercises every day. Please do them.
  • Participate in the forum for asking and answering questions or starting discussions. Share knowledge, and exchange ideas among yourselves during the course period. Participants are strongly encouraged to post technical questions, interesting articles, tools, sample programs or anything that is relevant to the class / lesson. Please do not post a simple "Thank you" note or "Hello" message to the forum. Please be aware that these messages are considered noises by people subscribed to the forum.
Outline of Work Expectations:
  1. Most of the days, you will have exercises to solve. These are there to help you assimilate whatever you have learned till then.
  2. Some days may have some extra assignments / food for thought articles / programs
  3. Above all, do take part in the relevant forums. Past participants will confirm that they learned the best by active participation.
