Introduction to Ruby I [ID:196] (1/6)

in series: Ruby Introductions

video tutorial by chingav, added 04/07

(Showmedo is undergoing major changes. To report any problems viewing the videos please email us and include browser and OS specifics. Cheers - Kyran.)

This video is a basic introduction to Ruby. It starts out with showing some of the basic reflection capabilities of Ruby such as (10**10).class. Then I talk about indefinite chaining of methods.

Other topics are if...elsif...else statements, method syntax, working with Arrays and Hashes, Hash literals, nil, and blocks, and a basic introduction to accessing Ruby documentation using "ri".

Thanks. Good tempo, I like the human mistakes too. I sometimes end up pausing the video to try out what you're doing in my terminal but since your presentation speed is well paced, I end up typing in my terminal along with you. Note: I'm also using Koans to help complement my online learning.

It's very good. a little bit confusing about the |x,y| x+y stuff.

Your "Introduction to Ruby" videos helped me a lot. Thxs a lot for publishing them. That saved my day :)

Thxs again...

Cool video... ideal for starters

26. anonymous Sat, 24 Oct 2009 08:50

Which IDE do you recommend? I am not a command line developer.

25. anonymous Fri, 28 Aug 2009 14:16

I needed to get a quick idea of what Ruby is like and this video jumped right in and told me, without unnecessary preliminaries.


24. anonymous Sat, 20 Jun 2009 06:16

Thanks for your vids: I've been trying to learn Ruby (and rails) and your introduction helps. Keep up the good work.

23. anonymous Fri, 19 Jun 2009 09:23

It' s well done

22. anonymous Tue, 16 Jun 2009 07:43

Somethings I found difficult to understand, but i am preety basic basic. Nevertherless, it was a very cool lesson! I DID learn!

21. anonymous Fri, 05 Jun 2009 08:24

hello world

20. anonymous Thu, 04 Jun 2009 15:23

Really nice vid !

thanks for your efforts. Great start

Need more examples of hashes, blocks and iterators and what they are usually used for.

I'm not a native speaker and had some problems to get every word (acoustically).

Some Ruby concepts like the |x,y| syntax need more explaination , I think.

Great introductory stuff! thanks.

Thanks to those who voted.

Thanks to all who have voted :)

Thank you Ryan. You have excellent tutorials on Rails as well :)

Great job! Excellent series you have here. :)


Yes, there is something like py2exe. It is called ruby2exe. I haven't used it yet. But here is the link:

If you want to create a Mac app, RubyCocoa should help:

You are doing great job there!

Cool videos!

Do you know if Ruby has something like Python's py2exe?

To join together the script and the interpreter, for easier distribution.


Thank you. I am glad you found them useful. You might also find useful(it uses Ruby as well).



6. anonymous Fri, 04 May 2007 11:06

Cool videos. They're really useful for someone who's starting Ruby and has no formal education in computer programming, like me.


Hi everyone,

In case anyone was looking at the simple script on my blog for running BlueCloth, I fixed a small typo (it should be gem install BlueCloth). I will mention gems and focus on debugging in the next screencast, when it is ready.



Thank you. I am glad you found these screencasts useful.



3. anonymous Thu, 03 May 2007 16:26

Great Job, I appreciate the work you put into these.

Hi everyone,

I think I will talk about debugging ruby applications and using the Ruby Development Tools for Eclipse in the next iteration, since there are a lot of votes for these two topics. Feel free to vote on other topics you would like addressed and I will see if I can work those topics in to one of my screencasts.



Chinmoy, welcome to ShowMeDo and thanks for providing this excellent Ruby introductory series. For the benefit of other viewers, could you reply to this comment and talk a bit more about other videos that you have planned?



Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software (FOSS)- with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for chingav
