Don't have words to applaud him.. mandatory video to watch for not only those who wants to work in Scala but for Java guys as well to see why you should move to Scala now :)
A very great teacher, presentor that combines humor and technicality to get his message through. One of the greatest speaker I have seen in youtube... same as those I see on TED Talks.
Cannot hold myself without commenting - Its a awesome tutorial for people who wish to learn Scala. Should be key for Hadoop developers as well who wish to use Scala in Spark.
I loved this tutorial absolutely. Funny way to learn the core Scala language. May be Venkat, you should write a Head First Scala book. It will sell like hot cakes!
nice intro, you have covered some key topics very nicely which help not getting scared from scala, will be good to understand this in a step by step manner, something like "thinking in scala" thanks
@25:42 Java is pass by value. Pass by reference would allow you to assign a new thing to a parameter inside a function that would then be visible outside the function.
***** It's been a while since the original post, so I hope I am responding to correct thing. In java if you have a function f that takes a parameter x, let's say of String, within the body of f you can change the value of x, e.g. set it to null. This will have no effect on the value that x held when the function was called. As a matter of fact, x did not even need to be a variable. That is what is meant by pass by value. I thing what you may be thinking of is the case where you pass in not a String, but let's say a StringBuffer. Again, if you set x, the StringBuffer, to be null within f, it will have no effect outside of f. You can, of course, update the StringBuffer, but this has nothing to do with whether the parameter was passed by value or reference.
Really very informative video, excellent content, awesome speech with humor ohh I just added a Trait BTW (with humor) :D. and I wanted to know, what is the REPL, Text Editor, IDE is used for this presentation.
This is a textmate script I wrote, it works similar to his: gatoprogramador (dot) snipt (dot) net/textmate-run-filescala-as-script/ (just set SCALA_HOME).
anyone know how to resolve this issue? That entry seems to have slain the compiler. Shall I replay your session? I can re-run each line except the last one. [y/n] You must enter y or n.

I wish I had watched this 4 years ago, instead of trying to follow 12-hour online courses on Coursera full of academical stuff and being bored to death.
Muhip, you mean the 'programming principles in Scala' course ?! The IDE setup on windows - 20 minute session was particularly painful with asian English accent that only their country can understand :-(.
Why even bother with the if(n == 1) guard, you can just write @scala.annotation.tailrec def factorialImpl(n: Int, fact: BigInt) : BigInt = n match { case 1 => fact case _ => factorialImpl(n - 1, fact * n) } Scala rocks... :)
He's arguments are very naive... For example: what's easier to notice during code review: var against val or private String against private final String?
Finally I video about scala where someone is actually writing code instead of display slides.
Deserves a standing ovation.
Indeed
This is really awesome! This is still relevant still after 11+ years since this content was published. Thank you! 🙏
One of the best technical presentations I have ever seen. Thanks!
+Alex McLintock what do you expect, scala programmed his brain and filled awesomeness.

Can't wait to listen to him again next week in SF JavaOne2016. I migrated to Scala last year after 13 years in Java.
The way he is speaking, has got my attention all along, didn't have to repeat the video at all. Excellent video.

This is exactly the kind of presentation I've been looking for.
Really good video that fills in the gaps most Java to Scala tutorials leave out. Great presenter too!
Excellent video! Learned so many things from this single video 👌 Great teacher
have been working on scala for a year now. A lot of missing things are cleared up here thanks venkat!
Scala and Clojure are making my life easier everyday.
One of the best talks on Scala.
Presenter,Presentation,Content -- Brilliant, loved it. Thanks Venkat !!

omg! I didn't even realise 1 hour 40 odd minutes. Before starting the video I was hesitant if I'll be able to make it. Wonderful talk
This guy knows how to give a good talk. Very informative with a bit of fun
I just started working on a scala project. This was an excellent introduction.
Been Binge watching Venkat's talks!
wow this is a game changer... just "tailrec" alone! awesome video!
This guy is fantastic
He is awesome!!! I'm totally buying his book.
Excellent teacher! I love his lectures!
Wonderful introduction to Scala. Very nicely organized and well explained.
nice intro, you have covered some key topics very nicely which help not getting scared from scala, will be good to understand this in a step by step manner, something like "thinking in scala" thanks
A very eloquent and energetic speaker. Loved watching the video.
He is the first person in the world who REALLY explained Scala to me. Btw what is the music? Greetz
very good presentation about scala, great teacher.
This is awesome and Venkat is amazing!
Awesome !! Superbly explained, Nice work Venkat !!
Exceptional explanation ! Very good head start to learn Scala.
Learn new things about trait in this video. So thankful!
This is awesome video and they way he present the things is superb!!!
Wow, that was a fun talk. Great speaker.
Lots of things to learn. Great Work

Great presentation as always.
it is a joy to watch this video.
superb narrator. well explained
Great introduction to Scala.
This is a fantastic presentation
Insightful talk. Really enjoyed it.
Wow Scala!
Great video!! Thank you!
awesome lecture as always!
Awesome , Really good teacher ....
How come this lecture has only 120k views? This is gold material. They can f**king charge for it!
one thing attracted attention: the statement that in java function parameters are passed by reference.
I am just wondering how can programming can be teach.. hats off sir.
Wow......Venkat u rock !!!
what a great teacher!
Really very informative video, excellent content, awesome speech with humor
ohh I just added a Trait BTW (with humor) :D.
and I wanted to know, what is the REPL, Text Editor, IDE is used for this presentation.
Tail call optimization starts at 46:00
Really awesome talk!
Superb explanation.
Really amazing presentation
Great presentation. Thank you
Fantastic talk. What editor is he using?
Great teaching
Simply Awesome
Great Presentation
Anyone know what compiler/IDE/Editor he's using there?
TextMate
IntelliJ IDEA Community Edition 14.1.5
Its not IntelliJ. I think it is Textmate.
Durga swaroop Perla Thanks!
you made Scala interesting for me :)
This is really good intro to Scala. Which REPL he is using here?
Wonderful talk!
This is a textmate script I wrote, it works similar to his: gatoprogramador (dot) snipt (dot) net/textmate-run-filescala-as-script/ (just set SCALA_HOME).
is e predefined for the elements?, if we had many lists which list would scala choose.
how to setup intellij in the presentation mode he has? with a nice background, compiler errors shown as baloon etc
Now I at least know it's IntelliJ
Its not IntelliJ. I think it is Textmate.
Scala is very cool!
Thank you. I finally got it.
anyone know how to resolve this issue? That entry seems to have slain the compiler. Shall I replay
your session? I can re-run each line except the last one.
[y/n]
You must enter y or n.

Abandoning crashed session. thanks in advance
Can anyone suggest me a followup video/book to know more about sealed, monads, effects, pattern matching etc?
Excellent....
Awesome !!
More, More, MORE!
-- Zoidberg
do you happen to know if sublime text 3 has a similar plugin?
Amazing
great dude.
Does anybody know how to setup BareBones TextEditor to work like Textmate as used in this video, basically compile and run scala code from BBEdit
?
53:36 "What are you smoking, this is not tail call optimized"
Excellent
I feel very happy！
I liked this talk but if I may nitpick...
factorial(0) = 1. He should have really done "if (n == 0)" rather than "if (n == 1)".
"Shared mutability is devil's work"
can confirm after just having taken an operating systems course.

What REPL is he using? This is not the standard REPL.
Which plug-in is this ?
Anybody knows which text editor he uses?
damn, this guy is awesome.
depends on india¿??
Very good presentation..
Good to see mitpress.mit.edu/sicp/full-text/book/book.html mentioned at 46:00
Why even bother with the if(n == 1) guard, you can just write
@scala.annotation.tailrec
def factorialImpl(n: Int, fact: BigInt) : BigInt = n match {
case 1 => fact
case _ => factorialImpl(n - 1, fact * n)
}
Scala rocks... :)
Fantastic presentation by an obviously brilliant guy, but he really doesn't understand cats at all!
He's arguments are very naive...
For example: what's easier to notice during code review:
var against val
or
private String against private final String?
+Jay Cris but who wants to type "final" all the time when you could just write an 'L' instead of an 'R' (val/var)
Below approach is better than using factorialImpl
@scala.annotation.tailrec
private def factorialWithTail(n: BigInt, accumulator: BigInt = 1): BigInt = {
if( n == 0 )
accumulator
else
factorialWithTail(n - 1, (accumulator * n) )
}
println(factorialWithTail(3000))
Ok, what's the music ?
Goood!!!
Mom told that sharing is good thing - Mutability lol :)
