Scala Days 2019

Scala Days had a tenth anniversary in 2019. It is an annual conference about Scala, which I like to visit, when possible.

There is some confusion as to what is meant:

  • Where this the 9th, 10th or 11th Scala Days?
  • Where the first Scala Days 9, 10 or 11 years ago?

The truth is, that the first Scala Days were organized in 2010 and took place in Lausanne. So it was 9 years ago, but the tenth event. For this reason it was done in Lausanne again, but in a much larger venue.

Just for the completeness:

This is the opening keynote by Martin Odersky. A video will be on youtube soon.

I visited the following talks:

And on the last day I visited the following talks and the diversity panel and the closing panel:

Here is the whole schedule.

Btw., links might expire when the next Scala Days will start using the site in early 2020. Where it will be in 2020 is still unknown, but since 2014 it has been a habit to do the even years in Berlin. I will try to come, if there are Scala Days 2020 in Europe.

ScalaUA 2018

About a week ago I visited Scala UA in Kiev.

This was the schedule.

It was a great conference once again, as it was already in 2017 and I really enjoyed everything, including the food, which was great again… 🙂

I listened to the following talks on the first day:

And I gave this talk:

On the second day I listened to the following talks:

  • Advanced Patterns in Asynchronous Programming, Michael Arenzon & Assaf Ronen
  • Akka: Actors Design And Communication Techniques, Alex Zvolinskiy
  • Monad Stacks or: How I Learned to Stop Worrying and Love the Free Monad, and other stories, Harry Laoulakos
  • Scala on Wire: How event streams help us build Android apps, Maciej Gorywoda
  • Purely functional microservices with http4s and doobie, Jasper van Zandbeek
  • Tame Your Data with Reactive Streams and Monix, Jacek Kunicki
  • Future and issues of the Scala Ecosystem, Panel Discussion
  • Roll your own Event Sourcing, Lina Krutulytė-Kriščiūnė

And I gave this talk:

As always there was a lot of inspiration coming from the talks and a lot worth exploring in future posts. So there will be Scala posts once in a while, as in the past…

Christmas Tree in Olten 2017

This message has been generated by a program again, this time I decided to use Scala:

import scala.util.Random
object XmasGreeting {
  val texts : List[String] = List( "Fröhliche Weihnachten",
    "Merry Christmas", "God Jul", "Feliz Navidad", "Joyeux Noël",
    "Natale hilare", "С Рождеством", "ميلاد مجيد", "Buon Natale", "God Jul!",
    "Prettige Kerstdagen", "Feliĉan Kristnaskon", "Hyvää Joulua!",
    "Glædelig Jul", "クリスマスおめでとう ; メリークリスマス",
    "Nollaig Shona Dhuit!", "Bon nadal!", "Срећан Божић",
    "Priecîgus Ziemassvçtkus", "Crăciun fericit", "Bella Festas daz Nadal!",
    "З Рiздвом Христовим", "καλά Χριστούγεννα")
  val shuffledTexts : List[String] = Random.shuffle(texts)
  def main(args: Array[String]) : Unit = {
    println(shuffledTexts.mkString(" — "))
  }
}
