Agenda: 18:00 Doors open 18:20 welcome, doors closing.. 18:30 From Reactive Streams, through Virtual Threads, to Flows - Adam Warski 19:30 break 20:00 Armeria: The Microservices Framework You Haven't Tried Yet - Dominik Dorn 21:00 networking **From Reactive Streams, through Virtual Threads, to Flows** Since Java's inception, the programming model has shifted from synchronous to asynchronous, and for good reasons: improved performance, higher throughput, and lower latency. Reactive Streams greatly simplified the development of reactive systems by incorporating elements of functional programming. However, with the introduction of Virtual Threads in Java 21, Java shifts back towards a purely synchronous model, while retaining high performance. Does this render initiatives like Reactive Streams obsolete? Can we combine the benefits of Reactive Streams with the approachability of Virtual Threads, the elasticity of modern Java, and the guarantees of functional programming? And what are the tradeoffs? **About Adam Warski** Adam Warski is the co-founder of SoftwareMill and head of R&D at VirtusLab, where he primarily generates code using Java, Scala, Rust and other interesting technologies. He is actively involved in open-source projects, such as Ox, Jox, Tapir, sttp, and others. He has also been a speaker at major conferences, including JavaOne, Devoxx, GeeCON and ScalaDays. In addition to writing closed- and open-source software, he spends his free time exploring various programming-related subjects. Any ideas or insights he gains usually end up on his blog ([https://warski.org/articles](https://warski.org/articles)). **Armeria: The Microservices Framework You Haven't Tried Yet** "One port to rule them all" .. that's the promise of Armeria, the microservice framework created by the creator of Netty, Trustin Lee. Armeria has built-in support for gRPC and Thrift, automatic endpoint descriptions (OpenAPI) and works with your Spring Boot App, your legacy Tomcat project or your dropwizzard app. We'll take a look at these (and more) features in this talk. **About Dominik Dorn** Dominik Dorn is a senior software engineer in Vienna and has been running the Java Vienna Meetup since \~2009. He has extensive knowledge in the Java and Scala ecosystems. He sometimes "tweets" on [https://x.com/domdorn](https://x.com/domdorn) . You can also find him on [Linkedin](https://www.linkedin.com/in/dominik-dorn/) where he happily accepts new connections from the community. He is doing freelance software consulting, so if your company needs help, he might have some resources left for helping you.

The money is secondary. One other thing that’s useful to know: - In the case of bad weather, we do have a back-up location that will protect us from the rain.

Agenda (preliminary) 18:00 doors open 18:20 welcome 18:30 Talk 1 19:30 break 20:00 Talk 2 21:00 Networking **A Tour of Ox 1.0: Direct-Style Concurrency and Resiliency** Ox provides a toolkit for safe concurrency and resiliency for Scala on the JVM. After two years of prototyping, we’re delighted to showcase the final product. With Ox, you can build and deliver direct-style Scala applications today. In the code-first presentation, we’ll begin with concurrency (including lower-level structured concurrency scopes and higher-level concurrency operators). Next, we’ll proceed to Ox’s approach to error management and type safety in that area. We’ll then explore Ox’s direct-but-reactive streaming library before concluding with its built-in resiliency toolkit. Software is never finished, so we’ll also share what lies ahead for Ox specifically and our plans for direct-style Scala generally. **About Adam Warski** Adam Warski is the co-founder of SoftwareMill and head of R&D at VirtusLab, where he primarily generates code using Java, Scala, Rust and other interesting technologies.

Weekly screenings from a large archive of many of the most significant, yet seldom seen and rarely accessible cinematic masterpieces in the history of film - from its earliest beginnings to the present day. Screenings are in original language, if English, or original language with English subtitles. Films are selected democratically on the inspiration of a brief pre-screening discussion. The selected title is typically a "neglected gem" that most of us discover together for the first time. Individual taste is not a criterion and all participants are expected to put the interests of the group as a whole above personal preference or prejudice. In this sense, the emphasis is on openness, exploration, and surprise. Each screening is followed by an in-depth group discussion, led and moderated by the curator. WARNNG: FilmStory is not just about watching movies! Rather, it's a socially responsible, intellectual engagement, involving an organic approach to group study of film language, philosophy, art, history, politics, and technology. In this sense, the film is always merely the current highlight in an explorative, ongoing group discussion. **FilmStory** is a members-only series that involves a closely knit community of cinephiles. Events take place every Sunday in a comfortable, private setting with limited capacity. Participation is reserved primarily for regular members, but we're always ready to make new friends! Non-regular members may request to meet the community and, upon acceptance as a "new joiner," are welcome to participate in one event, according to space availability. New joiners are asked to make a €6 member dues contribution in advance of the requested date. New members receive a message of confirmation and the address of the Living Room in 1080 Vienna upon receipt of their dues contribution. **FilmStory** is presented and hosted by **[KulturSalon Wien](https://www.meetup.com/kultursalon-wien/)**.

She has exposed her legs in a biblical city, an act they deem forbidden, and their judgement will echo on through her adolescence. When our narrator finally admits to her mother that she is queer, her mother's response only intensifies a sense of shame: 'You exist too much,' she tells her daughter. Told in vignettes that flash between the U.S. and the Middle East--from New York to Jordan, Lebanon, and Palestine--Zaina Arafat's debut novel traces her protagonist's progress from blushing teen to sought-after DJ and aspiring writer.
