This lecture is as funny as any sitcom. 😀😀😀 Nice delivery.

[@orlovskyconsulting]

EXACTLY MY OPINION ABOUT DESIGN PATTERNS! Mr Subramaniam make a good point!

[@vetri_vel]

Thank you very much sir. I learned a lot. My perspective towards the design pattern is changed.

[@Abitgenius]

There was not a single pause, great talk. Along with code samples, please share the shortcuts as well. thanks Venkat

[@SourabhBhat]

The mailer example is very interesting.

[@jorgeviana9130]

The intro is fabulous!

[@codingwithgraceandtruth2456]

great talk, impressive examples, thank you Venkat

[@wiilillad]

Design patterns only exist because OOP was an insufficient tool for communication and expression.

[@sodatta11]

Lambdas are like Beer. We all started with it disliking how it tastes.

[@pedrocarvalho1676]

THIS IS A PERFECT ANALOGY HAHAHAHA

[@NikitaYVolkov]

Welcome to the era of functional programming. Next stop is realisation that you don't need OO at all.

[@Minolrx]

I will diaagree

[@mirageman2]

Great talk, only the Q and A was a bit scary, better not ask anything :D

[@soyphea8697]

Wow this is how programming solve your daily life

[@dikatok]

already expected good stuffs from him even before watching the vid lol

[@iceadobe139]

Don't know if he is really talented or I'm just very stupid.

[@SaiKumar-vf9lz]

Completely makes sense after that intial thread example.. I'm like how dumb..

[@trozzonick77]

I was thinking the same :) about me .

[@kapilshekhar]

Shouldnt the send have Supplier of Mailer , instead of Consumer ? So that clients can create concrete Mailers outside execute and pass those?

[@chethannarayana7583]

how does var works in java virtual proxy example lazy using Supplier

[@programmingstuff4990]

what was it that he did at 8:01 ? Making a tick on the todo list in the editor. How to do that ?

[@JDLuke]

That is exactly what I'm trying to figure out right this second. Did you ever find an answer?

[@Masterrunescapeer]

On VSCode it's ToDo+, default toggle is alt+d for done. Todo+ has plugins for most editors.

[@rajdeepsharma3235]

Awesome

[@USONOFAV]

These are very useful. Is there like a book for this?

[@manishjangra5394]

There is a book called "functional programming in Java". All these topics are detailed explained in that book. Book author is same Venkat

[@bhaskartaneja6293]

till 17:04

[@andy12829]

Indian Brahmins are so intelligent he is just an example of it .. by the way Which IDE he uses as it compiles and shows value in real time ?

[@affemakla6884]

5:36 now i know you are extraterrestrial^^

[@nitinagrawal6637]

I don't hate design patterns exactly but I hate the way those architects boast about the design patterns in every meeting, as they know nothing except those & make the life of actual developers a hell...
