Good morning @lambdadays.bsky.social! Today, together with @michal.pawlik.dev, we will go through the history of Scala: there will monads, transformers, actors, singers and the meaning of being in a startup! Come coin us in Track 2 @13:30!

Thank you, @scalar-conf.com! I had a blast! Here are the slides for my talk "Retrying the retry design": michalplachta.com/slides/retries You can find the code (PoC!) at Github: github.com/polyvariant/... ("o rety!" is Polish for "yikes!" 💥) Blog post and hopefully some PRs coming next week 🤞

All the good ideas in my personal and coding life have come to me when cycling.💡 Hopefully I will be lucky enough to get at least the same time in the saddle this year too! All the best to you, blueskiers! 🎊

Make transformations, not mutations! 🌱 Instead of keeping a state and mutating it to access previous values... Think about the same problem differently: it's a stream of incoming immutable values that you need to transform into a stream of results. 🌊 No state = no problem

So cool to see “Grokking Functional Programming” being mentioned in a #Rust book! 🤩

One of my biggest mistakes, when I started programming functionally, was not using the right types. I always used the default List type when needed a list.🪲 But a List can be empty which might not make any business sense. We can throw an exception or use a different type! ✨
