Scala is the most beautiful programming language among the practical ones and the most practical one among the beautiful.

SCALA is turning 20 years old today!!! Congratulations to all of the language contributors and enthusiasts - what a journey that is! Let the Scala fiesta begin with the video of @adamwarski answering the most important question - why #SCALA? youtu.be/t7SOXNJVbJo?fe……
Let's be heard! I was told Scala had only ~200 responses last year. I feel like we need to bump this number by at least 2 orders of magnitude if we want to be considered a first-class citizen in new products.

If you're a #Scala user, the Scala toolkit is the thing you need. It provides the necessary libraries and setup when you're writing a new program, saving you time and shortening the process. Learn more in this #article by @SzymonRod. @scala_lang #Scala3 virtuslab.com/blog/scala-too…
We would love to hear from you! 📢 How do you use Scala @scala_lang? What parts of the ecosystem are vital for you? And what can we do to make Scala even better? The #Scala Survey 2022 is now open! Fill it out and influence the future of Scala. 💪 scala-survey-2022.virtuslab.com
@allenholub Sprint is just an outdated tool for protecting bad teams against pushy stakeholders. When engineers know how to incorporate changes, and when stakeholders understand the law of physics, you can stop wasting time planning sprints and focus on the essence of the problem.
@SeanTAllen @redrapids While immutability and pure functions do not *cause quality*, mutability and impure functions are definitely more likely to cause trouble. So even by cargo-culting, you've removed a big source of potential trouble, which is still a win.

Scala Times Issue #399 - mailchi.mp/softwaremill/s… powered by @deanwampler @DevInsideYou @FunScala2021 @jdegoes @johan__walters @kubukoz @lightbend @ScalaCon @ServerlessChats @zivergetech & others, thx!

This is why I prefer Kanban. ✅ Visualize flow, left to right ✅ Limit work in progress ✅ Work the bottlenecks Result: No incessant short-term incentives. No manufactured urgency. No requirements to finish by an arbitrary date.
Duplication is cheaper than the wrong abstraction, it's true. The right abstraction is still cheaper than both of those. Sometimes it's so much cheaper I've seen people build entire businesses from one insight. Duplicate where appropriate but don't stop hunting for the pattern.
