Scalar was a lot of fun and I saw some great talks (you should check out the Youtube channel!) If my talk on tagless final is interesting to you, I have expanded on it the current draft of my book "Functional Programming Strategies", which is at scalawithcats.com. (Yes, I need to get a new domain)

We’ve put together a photo gallery capturing some great moments from the hashtag#scalarconf - afterparty included ;) 👀 Check: www.flickr.com/photos/scala...

We had an awesome two days at @scalar-conf.com 2025 in Warsaw. It was a blast talking to Scala devs, getting their valuable feedback, and giving away swag (we need to order more of those hats 🤠)! Thanks to everyone who visited our booth and to @softwaremill.com for making it possible 🙏

I've really enjoyed attending @scalar-conf.com one more year, two in a row visiting Warszawa 🇵🇱! Met a lot of people in person, some for the first time, and learned a lot with talks. Plus the weather was as good as you can ask for polish weather 😂

Just added slides for my talk "Tagless Final for Humans" to my page of talks: noelwelsh.com/landing/talks/ I gave this talk today at @scalar-conf.com. The core is a new encoding for tagless final in Scala, which makes much better use of Scala's features than the standard encoding.

Thank you @scalar-conf.com for yet another amazing conference and for having me there! See you next year!

The last day of the @scalar-conf.com is over. Oh boy, what an adventure. 🎉 Many thanks to all the people who work to make it happen 🙏 Thanks to @rockthejvm.com for being such a great mentor and friend. Thanks to Martin for all the rest 😜

On my way to Italy 🇮🇹. Again, thanks to @scalar-conf.com and @softwaremill.com for such a fantastic organization 👏. The talks had an extremely high quality 📈 See ya! Don't forget to leave a star ⭐ to my project, github.com/rcardin/yaes 🙏

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 🤞

First of all, I'd like to thank my teammates from @scala.intellijidea.com with whom I attended @scalar-conf.com, and those who made our trip possible. Together we managed to get through lots of preparations, main hall talks, hallway talks, pre-, mid-, and after-conf talks... /1

First aftermovie is here! www.youtube.com/watch?v=ZOnz...

Getting creative at @scalar-conf.com !

Great to have you here @scalaspace.bsky.social Scala Center @jetbrains.com @softwaremill.com VirtusLab 💪

Yesterday at @scalar-conf.com I unleashed my efforts of tinkering with the Scala named tuples until I could push no more :) speakerdeck.com/bishabosha/g...

Yesterday was such a roller coaster! 🎢 I did my first talk ever to @scalar-conf.com, which was terrific. 🎉 Here is the deck: github.com/rcardin/scal... If you are there, let’s meet 🤩
