@RomanowskiKr Not exactly Tokyo coverage, but we're hosting a Scala meetup in 200k Košice, Slovakia Oct 11. Excited to see how it goes.

@runarorama Async flaky tests
Dependency hell

@KurtFehlhauer If you ever considered hiring EU based consultancy, I'm leading a team of enthusiastic Scala devs, please reach out.

[Michal Kaščák @kascakm]

@jaro_regec @scalac_io Wow, that's quite a comprehensive take on Scala. Nice job Jaro. You don't mind being featured in our newsletter right? 😉

[Michal Kaščák @kascakm]

@NicolasRinaudo Here's a lead, but I'm not sure it's related as the issue is for literals https://t.co/Z4b7yXRo38 @dwijnand ?

[Michal Kaščák @kascakm]

@alvinalexander Try/Either is more convenient for handling errors (e.g. propagating with 'map'). With the union types, you'd need to always pattern match, right?

[Michal Kaščák @kascakm]

@Krever01 Most of Typescript devs are 'evolved' Javascripters which is likely not something you'd want.

[Michal Kaščák @kascakm]

hey @mhevery . I'm wondering what are expected numbers of js files by default without any manual 'bundling' in #qwik ? E.g. for a big enterprise webapp (tens to hundreds of 'screens').

[Michal Kaščák @kascakm]

Contemplating if @scala_lang could have 'for comprehensions' without the for blocks. Similar to @roc_lang backpassing. All you need is <- comprehension.

[Michal Kaščák @kascakm]

Having background in Java, Scala, Typescript and a bit of experience in Elm and Rust I find the #roc language the most promising new generation FP language. I'm sold to all of the design choices. @rtfeldman does a tremendous job!

[Michal Kaščák @kascakm]

@_JamesWard I listen to only two podcasts: yours and @rtfeldman 's. Thank you both, it's very inspiring.

[Michal Kaščák @kascakm]

@jdegoes Doesn't F[_] wins all Typelevel users and 'a few' ZIO users. The few depending on maturity of the library? As an example to use http4s and ZIO since it's easy to integrate (because of F[_]) ?

[Michal Kaščák @kascakm]

@scalarconf What this means for TypeVille conf? Thanks!

[FOTF™️  @DefiningDone]

The Team at @HotovoMeansDone are looking forward to attending the @FunScalaConf in #London in next 10 days.. Check the schedule, filled with 50 talks from worldwide speakers!
- Learn about the #innovation happening in the #Scala ecosystem, including Scala3!

So what's the alternative to #akka if I need to spawn thousands of stateful concurrently accesed 'objects' with various lifecycle requirements. It should scale beyond single machine.

[Michal Kaščák @kascakm]

@adamwarski @zioscala Great post. I concur that service vs business logic semantics and respective DI is a bit confusing. I guess this will get better with experience on larger codebases.

[HOTOVO @HotovoMeansDone]

Hurray #openssl 3.0 was finally released in September and is already part of #nodejs v17 and brings in #quic and #http3 support.

[Michal Kaščák @kascakm]

@rockthejvm I prefer to explain 'monadic structures' to avoid being confronted with something not following all formal rules :)

[Michal Kaščák @kascakm]

@rockthejvm Sometimes supercryptic compiler errors. E.g. shapeless related 3 levels below application code.

[HOTOVO @HotovoMeansDone]

Most devs know standard falsy values in #Javascript. But there is document.all API. Returning HTMLAllCollection which is Array like and still falsy value! Despite having non zero length and being iterable.
