![VB.NET And SQL Database – Records Navigation Using Visual Basic .Net [ with source code ]](https://img.youtube.com/vi/DnAYjApOEtI/0.jpg "VB.NET And SQL Database – Records Navigation Using Visual Basic .Net [ with source code ]")
Excellent intro to Ruby for an experience programmer. Only thing I think should be improved is the part on polymorphism, which is a strange mix of inheritance, method overloading and duck typing
how many languages do he know?????
i have been downloading tutorial (on video tutorials) and have almost downloaded videos only from him. except sql
You lost me at 2 minutes. I am confused now. I thought it was easy lol.
Between 10:30 and 10:44 in the video, when you tried explain ‘unless’, you called the symbol ‘>” less than. That was a bit confusing.
I’m pretty familiar with Java so the change in syntax is pretty adaptable for me
Just video help me with a project for school. thanks.
what theme are you using?
Nothing about procs or lambdas?
Big like from me a php developer.
thank you for this video. It is very useful for me and it is so simple to understand ruby….. thank you once again..
Your videos are great for whetting the appetite or reinforcing concepts. I love the speed and density of information. Most excellent.
Ladies en Gentlemen, learn Ruby in 10 (or less) hours. Just watch this video 10 times! :-))
Just learning to code. Any tips?
Moving way too fast. Must be for intermediate users.
Wow that was a lot of information to grasp in 55.5 minutes. Thanks a lot.
Fantastic Voice and Content ! Cheers ! 🙂
creo que este video tutorial es mejor que el tutorial de codigo facilito ruby
Great video, earned my sub.
One question, can you use the “next unless” inside a for cycle?
Thanks!
you skip a lot of thing !! 😀
Derek, you’re an ace!
Really interesting video!
Excellent! Thank you!
Me: He’s writing a function called act_smart.
Derek:*writes return*
Me:He’s gunna write E=mc^2, isn’t he.
Derek:*Writes E=mc^2*
Me: *face palm*
why you need to add an “exit” to the end of the when clause?
what’s a string?
I, coming from quite a few other languages, find this one of the most refreshing videos about syntax of a language, on all of youtube.
I know other comments have said ‘too fast’ or whatever, I disagree. If you are a person who thinks this is too fast, and we were all there at one time or another, you really need to learn programming (language agnostic) first, if it just so happens to be with Ruby or Python, or whatever language you choose, look at the intro documentation on that language – it is better than any video will ever be for you.
I came to this video hoping to get a decent syntax overview, and that is exactly what Derek Banas did, and he did it quickly. If I am in the middle of creating an app – I can open up the documentation for what I am doing at that time, however, I was looking for a quick syntax overview and this is/was pretty awesome!
Thanks
I just don’t get the thing with Polymorphism. Shouldn’t it look something like this? ( You can call tweet method from bird (same as outside of bird) and ruby detects implementation automatically.
class Bird
def make_a_noise
self.tweet
end
def tweet
raise ‘not implemented’
end
end
class Parrot < Bird def tweet puts 'Squawk' end end class Cardinal < Bird def tweet puts 'Tweet tweet' end end p = Parrot.new p.make_a_noise
I’m watching this with 0.75 speed.
So I rly like ruby, but what is it actually used for ( without rails )?
Really really good, congrats bro!
you are amazing Derek!
man your tutorials suck, you just going so fast thinking we can keep up, you are coming from your point of view of already knowing ruby, but we don’t know ruby
Excellent, as usual.
You prob already know this, but you said statically typed at 38:50 when you appear to mean dynamically typed.
Exactly what i needed! Thank you very much @Derek Banas
The explanation is pretty good for beginners as me. It’s not easy to follow but the fast pace is appreciated. One can always go back and repeat the segment. There’s one thing I don’t get tough: how would you use enumerables to pick values from an array?
Great tutorial. I have one question though about File I/O. in 54min when you want to iterate over all the lines of the file why do you have to define a record and a line? Are they not the same thing?
just earned my subscription by skipping the boring installation part…. keep up Derek (y)
the code in 6:56, why you need to add a .to_s at the end of the line 3?
Nice video feels very streamlined and rehearsed.
very well explained. Thank you Derek Banas
