Confusion about Tagless Final
Let me highly recommend integration tests with testcontainers-scala, especially with Weaver Test using this snippet. Weaver is a great test framework, and testcontainers-scala is IMO simply the right way to do integration tests.

Parallel streaming in Haskell: Part 1 – Fast, efficient, and fun
Thanks for the explanation!
So it's pull based and not push based like most other streams lib.
Does maybe someone know how this compares to FS2 or Iteratees than? (Both are also pull based streaming solutions).

Looks quite similar to me. Is the Scala FS2 lib maybe even a clones of the Haskell solution? Or are they different in important aspects?

Should I Move From PHP to Node/Express?
On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.

fs2 for streaming.

Is “Functional Programming in Scala” 1st edition still relevant?
Finally, the last chapter has been rewritten to be based on some of the main design ideas from FS2 (https://fs2.io), which I hope will be more approachable than the 1st edition.

FS2 stream doesn't work as I expect it to
Just to clarify, is your doubt about the meaning of the api, or do you think you have found a bug? In either case, you can also open a Github discussion https://github.com/typelevel/fs2/discussions.

How to update and access state that needs to be shared across multiple API endpoints with FP?
Another more reactive solution would to use signals, as in FPR sinal network. fs2 implements this very nicely here https://github.com/typelevel/fs2/blob/8b285a6b54c63d43ed6aa3bb91365652035c90e5/core/shared/src/main/scala/fs2/concurrent/Signal.scala

Introducing effects systems S.A. ZIO at work?
Assuming the bug mentioned here is https://github.com/typelevel/fs2/issues/2568, we came up with a partial fix in a day (https://github.com/typelevel/fs2/pull/2569) and a complete fix in 2 days: https://github.com/typelevel/fs2/pull/2572. Note the original bug was opened on a Saturday. :)
