Offener Leseabend
## Wo & Wann?
**JEDEN MONTAG** findet die offene Lesebühne des Autorenforums Berlin statt (außer an Feiertagen)
**BEGINN**: 20:00 Uhr
**ANMELDUNG zum Lesen: ab 19:30 Uhr**
beim Moderator des Abends – siehe [Termine](http://autorenforum-berlin.de/wordpress/termine/);
Die Teilnahme an der Veranstaltung ist kostenlos.
**SCHWARTZSCHE VILLA**
**Großer Salon**
Direkt am S/U Rathaus Steglitz
Grunewaldstr. 55
Der offene Leseabend stellt das Herzstück des Autorenforums e.V. dar. Er steht nicht nur Mitgliedern, sondern grundsätzlich jedem Autor und jeder Autorin offen, der gerne einen unveröffentlichten Text vor Publikum präsentieren möchte. Auch Kritik kann jedermann üben. Wer lieber zuhören möchte, kann einfach am Montagabend um 20.00 in der Schwartzschen Villa erscheinen. Für Lesewillige gilt die unten stehende ausführliche Information (mündliche Anmeldung ab 19:30 Uhr).
*Unfortunately at the moment, it's only possible to present German texts. Unpublished texts that are already translated into German are highly welcome!*
## Was erwartet Sie?
Im Großen Salon der Schwartzsche Villa treffen Sie auf einen Kreis von Literaturbegeisterten, die Ihrem Text eine ernsthafte und fundierte Kritik spenden. Das Publikum wechselt. Es ist gemischt, geeint durch das Interesse an Texten.
Die Autorinnen und Autoren des Abends lesen aus ihren bislang unveröffentlichten Kurzgeschichten, lyrischen Texten, Erzählungen, Romanen, manchmal auch aus Theaterstücken. Die Autoren stellen nicht sich selbst, sondern ihre Texte der Kritik.
Wir verstehen uns als Arbeitsbühne. Deshalb wird bei uns nach den Lesungen nicht geklatscht.
Die Texte werden nach der Lesung des Autors auf handwerkliche Stärken und Schwächen „abgeklopft“. Es geht im Forum daher nicht um weltanschauliche Debatten. Im Idealfall hat der Autor/die Autorin nach einer Lesung und der Kritik verstanden, wo die Stärken und Schwächen seines Textes liegen, woran es seinem Text noch fehlt, was er ändern sollte und wo er bei seiner Überarbeitung ansetzen kann.
Der Abend endet gegen 22.00. Im Anschluss können Sie mit den Autoren im Café der Schwartzschen Villa noch ins Gespräch kommen und manches aus dem Literaturbetrieb erfahren. Wir sind im Kontakt auch mit namhaften Vertretern desselben.
Also – nicht gleich verschwinden! Dranbleiben.
Reden Sie mit den Forumianern!
## Sie möchten selbst lesen?
Wenn Sie selbst im Autorenforum lesen wollen, gibt es einige Dinge zu beachten. Wir bitten Sie sehr herzlich, sich mindestens einmal vor Ihrer ersten Lesung bei uns mit unseren Gegebenheiten vertraut zu machen. Ihren Lesewunsch können Sie dann ab 19.30 Uhr (Einlass) bei der Moderatorin oder dem Moderator eines Leseabends anmelden.
**Wir weisen ausdrücklich daraufhin, dass über die Annahme und Reihenfolge der Lesungen die jeweiligen Moderatoren entscheiden und es NICHT zwingend nach der Reihenfolge der Anmeldungen geht!**
In der Regel reicht die Zeit nur für drei Autoren je Abend und die Nachfrage ist oft recht hoch. Falls Sie einen lyrischen Text vortragen möchten, bringen Sie bitte mindestens 10 (zehn) Kopien mit, damit Ihr Publikum mitlesen kann. Die Kopien erhalten Sie selbstverständlich zurück.
# Wie üben wir Textkritik?
Nach der Idee von Maik Turni
## **Anschleichen**
**Wie wirkt der Text auf mich?** (Keine Angst vor Adjektiven! )
**Was habe ich gehört?** (Zusammenfassung (Nacherzählung))
**Was blieb unverstanden** (akustisch oder logisch)
## **Unter der Lupe**
**Was ist das für ein Text?**
(Prosa: Genre? Lyrik: Welche Art lyrischer Text?)
**Thema**
(Welches Thema berührt der Text? Hat der Autor sein Thema im Griff?
Ist es überzeugend/plausibel/gut recherchiert, vielleicht sogar zu faktenreich?)
**Figuren**
(Wie wirken die Figuren? Wer ist die Hauptfigur? Welches Problem hat die Hauptfigur?)
**Perspektive**
(Wie verhält sich die Erzählperspektive zum Thema / zu den Figuren?)
**Sprache**
(Welche Bilder sind stimmig / welche nicht?
Was lässt sich zum Rhythmus sagen?
Sind die Sätze syntaktisch und grammatikalisch korrekt?)
**Dramaturgie**
(Schafft der Text es, Spannung zu erzeugen? In welcher Reihenfolge werden die Dinge erzählt?)
**Bedeutung**
(Gelingt es dem Autor, die Bedeutung, die er seinem Text geben will, auch im Leser entstehen zu lassen?)
## **Klarspüler**
Fragen werden an den Text gestellt, nicht an den Autor!
Daher sollte der Text antworten.
## **Weichspüler**
Wird bei uns nicht verwendet.
Aber es gilt: Nicht der Autor wird kritisiert, sondern der Text!
Hart zum Text, sanft zum Autor!

German Sprachcafé at Denizen! From A1 to B2 *Read Description
**Hi everyone!**
We’ll now be meeting twice a week at Denizen House (Köpenicker Str. 40, 10179 Berlin), on **Mondays and Wednesdays**!
* **Mondays:** levels A1 to B2
* **Wednesdays:** levels B1 to C1
We work with dedicated materials tailored to each level, so everyone will have a place to practice and improve.
**Event schedule**
* **18:00 – 18:30** Arrival and registration
* **18:30 – 19:50** Sprachcafé
* **19:50 – 20:00** End and clean up
Please be aware that the moderated event starts at **18:30**. Before this time, we are busy setting up the space.
Registrations usually take place around **18:15 / 18:20**.
Participants are kindly asked **not to arrive too far in advance** at the house.
If someone arrives much earlier, Denizen may ask them to pay either for a drink (consumption) or for a **day pass**, as the space is a co-working environment during the day. **Please remember, our event is only happening from 18:00 to 20:00**
**How the Sprachcafé works**
We use different materials to help participants gain confidence in German. Together with whiteboards and our volunteers, the Sprachcafé is based on **interactive conversations** in small groups.
**Participation fee**
The Sprachcafé has a **participation fee of 5 €**, which helps cover organizational costs and **includes one soft drink for free**.
Tickets can be purchased directly on the day of the event, card and cash payments are accepted.
As the Sprachcafé has become very popular, we now need to **limit the number of participants**. Please understand this measure; it ensures that everyone has a comfortable space to practice.
We kindly ask you to be **rücksichtsvoll** and only RSVP “Yes” if you are certain you can attend.
If your plans change at the last minute, please update your RSVP so someone on the waiting list can take your spot.
Getting your ticket early can help secure your place.
**Please note**
Our event will begin **promptly** at the scheduled start time.
If you arrive late, we cannot guarantee your participation, even if you have a ticket or have RSVP’d.
We encourage all guests to arrive on time to ensure a smooth and enjoyable experience for everyone.
Thank you for your understanding and cooperation.
**About Denizen**
Denizen is a new-style co-working space focused on being an integral part of local communities.
Located on the ground floor of the historic Eiswerk on Köpenicker Straße in Kreuzberg, Denizen House is a communal place providing work, refreshment, and recreational facilities throughout the day. Think of it as a living room for the neighborhood.

Looking forward! Any questions please just message me.
Spring, Security, and Kotlin with Dmitry Chuyko and Alexei Zinoviev + WAD raffle
Just before everyone disappears for the holidays, let's get together for one more Java meetup!
This time we're joining forces with **Spring User Group**, and thanks to our friends at **JetBrains**, we'll be meeting at their office. We'll also have a raffle featuring **WeAreDevelopers World Congress** tickets and other prizes.

### **Kotlin and Spring Boot: From Messy Public Data to a Robust Application**
Real applications rarely get clean input. Source pages change, fields are missing, text formats are inconsistent, parsers make assumptions, and external services such as geocoders can be slow, incomplete, or temporarily unavailable.
In this talk, we will use a small Berlin-focused Spring Boot application written in Kotlin. It reads public demonstration data, parses semi-structured HTML, converts raw rows into a typed domain model, applies classification rules, geocodes locations where possible, and exposes the result through a Spring MVC API, an interactive map, and a timeline.
The Kotlin part is not a rewrite pitch. Spring Boot stays the familiar foundation for controllers, services, scheduling, database access, and operational endpoints. Kotlin helps in the parts where enterprise code often becomes defensive and noisy: nullable input, parsing results, rejected rows, domain identifiers, explicit states, and readable transformation pipelines.
A central part of the example is a small Kotlin DSL for rules. The classifier is not AI and not a black box: rules are written as type-safe Kotlin code, close to configuration, readable in the IDE, and able to explain why a certain operational risk score was assigned to an event or route.
We will also look at what makes the application robust in practice: handling parser failures, conversion problems, missing coordinates, partial results, and unstable external services without turning every expected problem into a generic HTTP 500.

\#\#\# From Kitchen to Table: A Safe Software Journey with SBOMs
The EU's Cyber Resilience Act (CRA) is turning Software Bills of Materials (SBOMs) from a "nice to have" into a legal requirement for many software products. Managing your software supply chain is no longer optional—it's part of shipping software responsibly.
Think of your containerized Java (and Spring) application as a dish served to production. Every ingredient matters, and someone will eventually ask what's inside. SBOMs are the ingredient lists that security scanners, auditors, and regulators rely on.
In this practical session, we'll look at how Java and DevOps teams can make SBOMs part of their everyday workflow. We'll cover:
* generating and managing SBOMs in CI/CD (GitHub Actions and GitLab CI)
* verifying pre-built container images
* enforcing supply-chain policies in Kubernetes with OPA and Ratify
* navigating SPDX vs. CycloneDX
* integrating SBOMs into existing toolchains without unnecessary complexity
Rather than treating SBOMs as compliance paperwork, you'll learn how to use them as actionable security artifacts that improve visibility, strengthen your software supply chain, and help meet regulatory requirements.

**18:00** – Doors open
**18:30** – Alexei Zinoviev
**19:00** – Networking break
**19:30** – Dmitry Chuyko — *From Kitchen to Table: A Safe Software Journey with SBOMs*

Lessons from the Field: Scale, Availability, and Performance
**[IMPORTANT NOTICE registration is HERE](https://luma.com/wh28yfqv)**
**Please bring a valid ID (driving licence or passport) with you on the day, as it will be required for entry to the venue.**
Join **Aerospike** **AWS, Adjust and Miro** for an evening of technical talks focused on the challenges of running real-time, business-critical systems at scale.
Hear firsthand lessons from engineers managing large datasets, database migrations, and cloud infrastructure availability in production. From Miro's Redis-to-Aerospike migration on Kubernetes to AWS best practices for capacity planning and resilience, speakers will share practical insights gained from operating demanding workloads where performance and reliability matter.
Connect with fellow engineers, architects, and technology leaders from Berlin's tech community over drinks and networking.
**Agenda**
**17:30 – 18:00 - Welcome & networking**
**18:00-18:10 - Speed vs Capacity: Designing Data Systems for Real-Time Scale**
*Dirk Möller, Regional Lead Germany and EE, Aerospike*
In high-performance data systems, balancing RAM and disk is key to real-time performance at scale. This session explores the technical nuances of database architecture in today’s AI-driven era, where workloads demand low latency, massive scale, and adaptive infrastructure. Drawing on real-world, mission-critical systems, we’ll show how to achieve the right mix of speed, scale, cost-efficiency, and reliability - designing architectures that meet today’s real-time demands while staying sustainable and affordable.
**18:10 – 18:30 - Scaling Beyond Millions of Transactions**
*Leonardo Muñoz, Platform Engineer, Adjust*
A behind-the-scenes look at how Adjust powers high-throughput, low-latency workloads at scale using a distributed database platform running on bare metal infrastructure. Leonardo will explore the architectural and operational decisions behind the deployment, the challenges of managing dedicated hardware at scale, and the lessons learned from years of production experience supporting mission-critical workloads.
**18:30 – 18:50 - Pod Ready ≠ Data Safe: Migrating a Critical Dataset on Kubernetes**
*Yuriy Chernikov, Staff Software Engineer, Miro*
Miro migrated one of its most critical datasets from a legacy caching platform to a modern distributed database running on Kubernetes - and not everything went according to plan. This practical talk covers what the migration actually required, the design decisions that made failures survivable, and the operational lessons that only emerge when managing datasets measured in terabytes.
**18:50-19:10 - Managing Amazon EC2 Capacity and Availability**
*Nati Cohen, Sr. Specialist Solutions Architect, Compute, AWS*
Modern data-intensive applications require infrastructure that delivers high performance, scalability, and resilience. Organizations often seek to leverage the latest storage-optimized EC2 instances, select larger instance sizes for improved performance, place infrastructure close to data producers and consumers, and scale efficiently as business demands grow.
In this session, we'll explore how to balance these performance requirements with cost optimization and capacity availability. We'll review the various EC2 capacity and reservation models, including Capacity Reservations, On-Demand Instances, Savings Plans, and more. Learn how to combine these options to optimize cost, performance, and availability for large-scale production workloads
**19:00-20:00- Networking**

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
