This guy showed us all software methodology used in real-world :p - IDE Driven Development - TERROR Driven Development - Copy-Paste Programming - Jesus Driven Development Great Talk!!! I left Java for Ruby few years back, now after watching this, I wanted to try Java again.
Legit!!!!!! No bullshit mathmetical crap. No "a monad is a monoid of in the category of endofunctors" BS. Just straight, clear, legit usecases and legit solutions that so happen to be functional!
One of the greatest technical conferences I have ever seen! Not just a very skilled Java developer, but also a showman! Impressive typing speed as well
Very inspiring programmer. I am following vids on this channel quite often but you made me subscribe to the channel. Thanks for the wonderful compilation.
Nice Job. Thanks. I'll go through it slowly again How is he doing the Auto-typing. (Noticed that the Eclipse Editor Cursor is on top but typing happening on bottom.) This will come handy for presentation.
A great professor, too, I bet!!! Also i looove how he doesn't use any pretentious monoid/higher level math bs that has little to do with actually solving problems.
At first I thought the same thing...Pretty sure he backspaced the text then is CTRL+Z'ing (he loves his Z!) to get the text back, notice there's no typos for those bits?
Terror Driven Development: L-o-v-e-d it! 🤣 Thank you for a very good, entertaining and engaging presentation! Of course, lambda functions have their place under the sun but I see the point.
I wish , Java will come with built-in alternative to Lombok. Something like case classes in scala. Bcoz when we think from server less point of view, adding too many dependencies causes cold start issue.
I was wondering if what I was thinking about for the last few months were crazy ... I'm glad that someone else with more experience confirms that I'm not crazy. Were is the Monad interface in java ? :(
Code at 8:11 really bad. But in my recent scala gigs I have came across code which make this innocuous. It seems more functional a language is, coders tend to write really bad unreadable unmaintainable code...just my observation.
Nice talk but I disagree that throwing runtime exceptions instead of check exceptions is a good habit. In functional programming side effects (exception) should better be declared. A good example for this is vavr "Try" (see vavr.io: www.vavr.io/vavr-docs/)
But it is a good habit if you want to play with nice feature in Java 8 as lambda. And IMO about treating checked/unchecked exception you can write your own Try monad for your purpose.
Checked exceptions should have not been invented because they lead to intolerably ugly code. If the they were never invented and the convention was to add a 'throws' that specifys all the unchecked exceptions used - I wouldn't have a problem. In our world, you either wrap them or disgustingly handle them.
"Got away without using an if". They're still used under the hood, you're just moving the logic behind magic methods. I agree that you should be using these tools, but like every tool, it should be applied with some sanity checks.

Great Talk!!! I left Java for Ruby few years back, now after watching this, I wanted to try Java again.
epic "Oh by the way, I'm using Eclipse"
This is an informative yet hilarious talk. Love this guys way of teaching!
Extremely high energy that rubs off even through this medium. The epitome of passion. Folks from all walks of life can learn from this guy.
Oh my god. amazing and explanative talk. thank you my friend. maybe the best functional programming talk I have ever watched!
Legit!!!!!! No bullshit mathmetical crap. No "a monad is a monoid of in the category of endofunctors" BS. Just straight, clear, legit usecases and legit solutions that so happen to be functional!
One of the greatest technical conferences I have ever seen!
Not just a very skilled Java developer, but also a showman!
Impressive typing speed as well
Despite learning almost nothing, I really enjoyed this talk. Very intense.
This dude is absolutely insane. I love it.
The lessons here are directly applicable at my current job. Let the refactor begin.
One of those best talks I have ever heard. Truly informative. Purely amazing!
Awesome speaker, you did a good job
Such a lively and informative talk.. so nice to learn from you.
Check out my other talks on www.victorrentea.ro/#talks
the presentation is very helpful. provide several ways to improve my code. thanks a lot.
I really enjoyed watching this talk
The guy is hilarious! Enjoyed the talk.
I've seen like 4 videos of this guy of 1 hour each and I'm pretty sure I can introduce him on any stage with all his history and credentials xD
That very case when I hit “like” even before the video has ended.
this is my favorite talk!
learned and laughed. I enjoyed this presentation. Victor's energy is amazing.
A big thank for this talk.
What an awesome talk by him, really enjoyed it!
Sticker driven talk... liked it!
That unchecked consumer is realy useful.
I think with Java 8 now it is time to work again with Legacy code!
Soooo much experienced
This is just just amazing...! Great great talk
Very inspiring programmer. I am following vids on this channel quite often but you made me subscribe to the channel. Thanks for the wonderful compilation.
Excited to watch this talk. Usually I wait to post until after I watch a video but in this case, I'm the first view and I do have to declare... First!
Nice Job. Thanks. I'll go through it slowly again How is he doing the Auto-typing. (Noticed that the Eclipse Editor Cursor is on top but typing happening on bottom.) This will come handy for presentation.
I loved this man, so friendly talk and informative. I've learned a lot today. :D .. I want a sticker too!!
Great presentation combining learning and fun. Thank you :)
Can’t appreciate it more
Excelent. Thanks man!
Oh my good, I still love Eclipse forever
I like your style
A great professor, too, I bet!!!
Also i looove how he doesn't use any pretentious monoid/higher level math bs that has little to do with actually solving problems.
9:00 he's the Art Tatum of keyboard typing. You can`t seven see his fingers moving yet he's firing code faster than Usain Bolt on steroids.
At first I thought the same thing...Pretty sure he backspaced the text then is CTRL+Z'ing (he loves his Z!) to get the text back, notice there's no typos for those bits?
Terror Driven Development: L-o-v-e-d it! 🤣 Thank you for a very good, entertaining and engaging presentation! Of course, lambda functions have their place under the sun but I see the point.
Great presentation.
I wish , Java will come with built-in alternative to Lombok. Something like case classes in scala.
Bcoz when we think from server less point of view, adding too many dependencies causes cold start issue.
good tips!! At the same time have we discovered the fastest typist in the world?
I was wondering if what I was thinking about for the last few months were crazy ... I'm glad that someone else with more experience confirms that I'm not crazy. Were is the Monad interface in java ? :(
Awesoem dude, should moonlight as stand-up comidian! xD
Great talk!
this is how we should keep audience active
How did he draw lines over the IDE?
thanks a lot , very good
greate lecture by the way
For lack of a better word.. Great!!!!!
Awesome
This was SUCH an energetic and charming presentatiom!
ALSO, he's Spanish (I bet) which explains the lisp.
He's Romanian, actually.
What if the Type is being set in runtime? Add a predicate to the enum constructor and then map to the algo after?
This guy is hilarious
Cameraman needs to attend photography's devoxx
Amazing
brilliant
That's too bad I would have liked to listen the Christmas story about Monads!
How can you use that BiFunction-solution when you don't have the ability to change the enum class? Such when you use another library fo example
Could we use adapter pattern to apply on it?
Epic

Functions become first class citizens as objects in Java 8. :)
What version of Java was used in this talk? Meaning no need to use BiFunction anymore, right?
@@jean4j_ Java 8...?
Wow
He is exactly how I think God looks like.
wow
"Got away without using an if". They're still used under the hood, you're just moving the logic behind magic methods. I agree that you should be using these tools, but like every tool, it should be applied with some sanity checks.
He lives in the futur
not(isDeleted) is better than isNotDeleted
You speak Java, but you also speak fRRRench.
This guy is talking at 1.5 speed by default
He gives me ADHD vibes, he speaks very similary to someone I know IRL who has ADHD.
wow C# can do this since 2008
Borat of programming
