He says something about modules, that they are important but that people don't understand them. I'm one of those people. Where can I learn what he means by that?

11:14 - Why mention Rust, Rust is horrible. "I shall makest thy life unbearable by promising to solve the problems that thou dost not hast".

I agree the documentation is already top notch

Simply, Contravariance is for input, Covariance is for output. That was very helpful for understanding contravariance. Thank you!

Scala is actually the best. Industry hasn't caught yet.

An idea for another video: Can you show how to extend this application to have some dependency injection / context? I understand this will not be “Tapir only” video, but it will help people bridge the gap between theoretical use of Tapir and a real world use of it

In 18:00, wouldn’t it work if you use “AvatarError.Unauthorized.type” 🤔

I am planning to use this with zio http

good overview, thank you very much!)

The final effect is at 30:29 - automatic edge detection and a nice message - enjoy!

Nice, I didn’t know there is a mapInto macro 😮

Again, so good!

Idea for the next video: How can you express multiple error types and especially if you want to combine different errors in an ad-hoc manner using a untagged union.

This is why I love my job! Mentally with you!

How do we write logging messages in Scala? I'm not expecting answers like "what's wrong with logback? log4j? ..." as I know that we can use Java libraries in Scala. I'd like to know the common/popular ways to do that in Scala.

Thank you!, I would like to know how authenticate endpoints

This really adds a lot of value, we're missing a lot of clear explanations such as this one in the ecosystem! Thanks for all your work :)

I love this so much!

Great tutorial. Is there a way to describe websocket messages with OpenAPI, or how would you go about it?

I find this tutorial excellent. Anyone looking to build an API and having swagger documentation will surely find this useful. Great work!

Sadly the nausea causing bass sound from typing I commented about on the first video still persists :(. Separating the microphone from the desk would be one way to get rid of that.

Wow! Great! I will try tapir 🎉

I would be interested of a series for tapir, but before that I'd suggest separating the microphone from the desk, or adding dampening for the microphone, as in this video your typing causes low bass sounds that make at least me nauseous. I wasn't able to watch anymore after you started working on the code :(

Adam, great work! Already using tapir and it is such a lovely tool. It is making Scala world richer. The learning curve of the library is low but also allows for advanced usage. Having different options for servers, clients and almost built in Swagger UI integration makes writing HTTP API very simple. Thank you for such great set of libraries!

Why does your IntelliJ not show any code hint (i.e. the arguments of a method, the methods in a class ...)? I think IntelliJ already supports scala cli? You can go at a faster pace and put more examples (at least, that's what I like. If I like it, thousands of Joe developers like me will like it too). For example (this is what I copy from Spring), how to make the query parameter optional, if the query parameter is missing, can I give it a default value, does tapir help converting the string value of a query parameter to another type that I specify, how to catch all the query parameters even when I don't declare all of them ... If tapir can provide all the features Spring has, ... well I don't know what will happen then :)

Great idea! I hope there are more video tutorials on Tapir 💡

Please continue this series n keep going, thanks a lot for the video

Thank You!

Scala is a beautiful language at its core especially v3. Too bad it was made complicated and esoteric and as a result lost mindshare among developers. Scala 3 should have been a different language with different branding and not tied to JVM. Unfortunately they constrained themselves with the technical debt of old Scala. How sad 😢

You worked with Java from 2011 - 2013: that means 2 years with Java 6/7 (java 8 was released Mar 2014). That also means you might not know much about the current java language features. You use Scala in your personal projects: I guess you're up to date with Scala. You're using Kotlin at work, you must be pretty good at Kotlin. Looking at your Scala example, I'm not sure how many spaces you use for 1 indentation. Sometimes 3, some other times 4? IMO, it's a magic if your Scala 3 example at 7:53 compiles.

Hello. I would like to apply similar pattern to run Akka Persistence on AWS Lambda? Don't you have a code snippet you can share with us?

4:54 counting 20 people in the audience

I am quite surprised this could be done without a change in the compiler! I suppose the 'derived' method on the typeclass' companion object has no restriction on the type of the first argument then.

Thanks for this talk. Great Engineering !

What about having monads/arrows/applicatives be "hidden" say by the eval function so that you are inside the monad at the start, but you can change the current monad using let/where

Hi Nguyen, you're just at the 2nd year of your phd program but you already went through Rust, Nodejs and Go. How much time did you spend on each of them?

Nice talk, understandable code!

great demo, can it be open-sourced?

Great work m8!

Another question: why is Jox pretty slower than the Kotlin channel when they both use the same design? Is it possible that the jvm bytecode generated by Kotlin is better than the one generate by javac?

While I really like scala, I don’t get why someone would like to do this. I am missing the motivation part at the beginning of the talk - is it something else other than just having fun and showing that it is possible? And as a side note: why did you upload the video in such a format @Scalar conference organizers?! It is really hard to see anything on the code part. Make it full screen next time please

So select gives us the result of the 1st completed task (if there are n tasks, each of them must have its own channel, right?). Will it cancel other tasks when 1 task finishes?

Does this work ok in Scala 2/3, given the correct JDK?

Amazing. Thanks !!!

😂

We are in a chainable simulation with infinite possibilities

The video description is wrong! It's for another video about ScalaPy.

I’ve never understood Martin’s use of “simple” when describing Scala. There is nothing simple about Scala.

Unfortunately the wokeness destroyed Scala.
