Did you ever want to build a web application? Perhaps you even started down that path in a language like Java or C#, when you realized that there was so much “climbing the mountain” that you had to do? Maybe you have heard about web services being all the rage, but thought they were too complicated to integrate into your web application. Or maybe you wondered how deploying web applications to the cloud works, but there was too much to set up just to get going. In this course, we will explore how to build web applications with the Ruby on Rails web application framework, which is geared towards rapid prototyping. Yes, that means building quickly! At the conclusion of this course, you will be able to build a meaningful web application and deploy it to the “cloud” using a Heroku PaaS (Platform as a Service). Best of all, it will almost feel effortless… Really! “But wait”, you will say, “there is no way that we can build a useful application if there is no database involved. You need the data for an application to be useful.” Great point! But what if… instead of getting the data from the database, we get it from the internet by tapping into one of the web services out there that readily provides data needed by our application? “Ok, but that’s probably very complicated”, you will say. Take this course and you will be pleasantly surprised at just how easy it is!...



I have played around with Ruby on Rails before but this course really helped me understand the nots and bolts. It is worth replicating all the examples shown in the videos to get a good understanding,


One of the most challenging things I've ever done.\n\nThe course goes from zero to web deploy in 3 weeks and there are more to enjoy, discover and learn....\n\nTry it, I't's a no-return voyage

Short course but enough challenging and interesting. I really like the short course to update my skills on web development...3-5 week course are really good!

The course is not only very didactic and general in some aspects, it's also a course that teaches great usable content beyond the just ruby on rails panorama.

Excellent course for me, I've been a regular Java programmer, yet the pace this course offered is suitable for me. Not too fast and not too slow.

Gracias! :)

Kalman Hazins is a great instructor. His lessons are well prepared, no fluff, to the point. As a bonus I can imagine getting taught by Christpher Walkin.

A straightforward and easy to follow, yet useful and straight-to-the-point course. If you were a beginner in Ruby on Rails, I recommend this course.

I learned a lot. I would highly recommend it to others. I feel I've mastered the foundations of both the Ruby language and the Rails framework.

At first it turns up a little difficult, especially the second week but it's all there.

The community was great, the discussions helped me a lot.

So far, I've really enjoyed the course. However, I've had some problems with installing ruby on windows. But nothing google can't fix.

The first Web Development course I enjoyed - instructions were clear, tasks were not that trivial and above all - practical.
