## 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 Unpublished texts that are already translated into German are highly welcome!* ## Was erwartet Sie?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!

Zalando is graciously hosting us for our first Meetup in 2026. And we are doing it a bit different: we have two rooms, and two talks in parallel. This gives you the opportunity to choose between two talks, for a total of four talks. This year, we’re especially happy to welcome Amazon Web Services as the food sponsor for our meet-up. Thanks to their support, our community can enjoy great conversations over great food — making the evening not only insightful, but also delicious. Meet the AWS experts Sikandra Chaudhary, Daria Aleshkova, and Narendra Tawar. Narendra will be delivering a talk on PostgreSQL and AI, sharing practical insights and real-world experience. We truly appreciate AWS’s commitment to supporting local tech communities and helping us create a warm, welcoming atmosphere for everyone. **PLEASE BRING YOUR PHOTO ID** **USE THE MAIN ENTRANCE TO BHW ON THE SIDE OF UBER ARENA** **Agenda** Two sessions run in parallel in rooms codenamed "Auditorium" and "Festival" **18:30** \- doors open: registration\, networking\, and drinks **19:00 - 19:05** Auditorium, "Event intro" by Sergey Dudoladov, Senior Database Engineer in Zalando. **Auditorium: Track A** **19:10 - 19:55** "How we made WarehousePG Open Source (again)" by Andreas 'ads' Scherbaum, a WarehousePG Principal Engineer at EDB and a Founding Member of PostgreSQL Europe **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups" by Tudor Golubenco, CTO of Xata **Festival: Track B** **19:10 - 19:55** "The Role of PostgreSQL in the AI World" by Narendra Tawar, Sr Database Specialist SA, AWS **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "Modernizing Postgres Communication with Hackorum", by Kai Wagner, Percona **21:00 - 22:00 Networking, Q&A, and pizza** **22:00 - The End** **Abstracts** **How we made WarehousePG Open Source (again)** WarehousePG is an Open Source fork of Greenplum Database, which by itself is a fork of PostgreSQL. The project was born after the upstream project was made closed source. This talk gives a quick overview of the history of both projects, which already spans more than two decades. We then dive into the reasons for creating a fork, and all the stumbling stones we had to pass in order to make this project open source again. We also talk about the challenges of CLAs (Contributor License Agreements) and what implications the PostgreSQL and Apache Licenses have for the project. Speaker: Andreas 'ads' Scherbaum **The Role of PostgreSQL in the AI World** As artificial intelligence (AI) continues to revolutionize industries, the need for robust, scalable, and efficient data management solutions has never been greater. PostgreSQL, with its extensibility, performance, and advanced data capabilities, plays a crucial role in enabling AI-driven applications. This talk explores how PostgreSQL supports AI workloads, from managing vast datasets and integrating with machine learning frameworks to leveraging extensions like PostgreSQL ML, TimescaleDB, and JSONB for AI-ready storage and querying. Attendees will gain insights into best practices for using PostgreSQL in AI pipelines, optimizing performance for AI inference, and harnessing the power of open-source innovation to drive intelligent decision-making. Whether you're a data engineer, AI researcher, or PostgreSQL enthusiast, this session will showcase why PostgreSQL is an essential component in the AI ecosystem. **From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups** CloudNativePG (CNPG) is a popular and battle-tested operator for running Postgres on top of Kubernetes. At Xata, we’ve been using CNPG and extending it in several different directions. One of them is implementing a scale-to-zero plugin: clusters hibernate when inactive and they wake up automatically when new connections are created. After adding scale-to-zero, we’ve faced the challenge that the CNPG wake-up from hibernation is rather slow.This is an optimization story about how we reduced the wake-up times from 20+ seconds to under one second. Speaker: Tudor Golubenco **Modernizing Postgres Communication with Hackorum** In 2026, the debate over whether mailing lists are still "state of the art" continues to divide developers. While some view them as relics, we cannot neglect the unique benefits of their decentralized, archival nature. Rather than fighting over platforms or ignoring the friction, Hackorum asks a simpler question: Why not just improve the user experience? Hackorum transforms the daunting mailing list "firehose" into a modern, forum-style interface without breaking the underlying email culture. It is designed to lower the barrier for new contributors while providing power tools for veterans: Seamless Integration: Real-time sync between mailing lists and daily sync of the Commitfest status. Modern UX: Per-message read tracking, tagging, and contributor profiles. Enhanced Coordination: Shared notes and mentions to streamline complex reviews. We have to stay open minded and willing to expand our horizon and as such Hackorum is rapidly evolving. While our roots are in development, we are currently expanding to include broader mailing lists like -general and -docs. Our goal is to make the entire Postgres ecosystem more accessible and usable for everyone. Join us for a demo of the latest updates and help us shape the future of Postgres communication. Speaker: Kai Wagner **About the speakers** **Andreas Scherbaum** has been working with PostgreSQL since 1997. He is involved in several PostgreSQL related community projects, member of the Board of Directors of the European PostgreSQL User Group and also wrote a PostgreSQL book (in German). Since 2011 he was working for EMC/Greenplum/Pivotal and tackled very big databases. Until 2024 he was doing the same - but with maybe even more and bigger databases - for Adjust GmbH in Berlin. Now he's working at EDB as WarehousePG Principal Engineer and is helping customers with even larger databases. **Tudor Golubenco** is the CTO of Xata, a Postgres platform with branches and zero-downtime, reversible schema changes. Before Xata, Tudor worked as a tech lead at companies like Elastic and Oracle. **Narendra Tawar** \- Sr Database Specialist SA I am accomplished database professional with 21 years of comprehensive experience across Oracle, PostgreSQL, Microsoft SQL Server, and MySQL environments, with specialised PostgreSQL expertise since a decade. Currently serving as a Senior Data Migration Specialist at AWS, I architect and execute complex enterprise migration strategies while actively expanding into Generative AI technologies to enhance migration efficiency and optimize data workflows. My core competencies include database architecture, performance optimization, migration planning, and cross-platform data integration, combining decades of hands-on experience with modern cloud methodologies to deliver scalable, reliable data solutions that bridge traditional database principles with emerging AI capabilities. **Kai Wagner** \- I’m Kai\, a Senior Engineering Manager at Percona with almost two decades of "bleeding" open source in my DNA\. From the Linux Kernel and Ceph at SUSE to leading PostgreSQL development today\, my career is built on a foundation of transparent communication and community\-driven innovation\. In my free time\, I'm a handball\, agility and movement coach for various ages and teams\, next to spending time with the family and on the house\. **Note** We will again take notes who signs up and does not show up. This information will be used to provide seats to others at future events. Plain and simple: please only sign up if you plan to attend.

On the 3rd March we will host the next iteration of our monthly Audio Developer Meetup. The long talk will be by Christian Grothe on building audio applications for the terminal in rust. The short talk will be by Maksymilian Padalak on how to convert text prompts into plug-ins. See below! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd Talk details: **Building Audio Applications with a TUI in Rust** \- Christian Grothe In this talk, we will explore the possibilities of building musical instruments with a terminal user interface using Rust and Ratatui. We will look at both the challenges and advantages of this approach, illustrated with practical examples and sound demonstrations. **Christian Grothe** is a programmer and musician based in Potsdam. During his music studies, he became increasingly interested in creating improvised electronic music using his own tools. Starting with MAX/MSP, exploring the Axoloti board, experimenting with Arduino and Teensy, and eventually building an analog modular synthesizer from scratch, his technical abilities evolved through time and hands-on experience. Primarily focused on building tools for live sampling, Christian settled on a stack where he uses Rust to create custom sampler instruments running in the terminal, alongside SuperCollider patches—literally making music with tmux. **pluginmaker.ai - How We Turn Text Prompts into Working VST/AU Plugins -** Maksymilian Padalak pluginmaker.ai is the first ever browser-based, no-code generator for VST and AU audio plugins. Users describe an effect or instrument in plain language - "plate reverb with decay and damping controls" - and within minutes receive a plugin they can load in almost any DAW. In this talk they'll demo the full flow from prompt to plugin, walk through how the generation pipeline works at a high level, and share what they've learned building an AI system that writes real-time audio code. Maksymilian Padalak is an ex-Nord Security (NordVPN) developer, guitarist, music producer, former professional standup comedian, and co-founder of pluginmaker.ai - an AI-powered platform that generates audio plugins from natural language descriptions. He co-founded the project with his best friend and ex high school bandmate Dominik Bilski, an ex-FedEx and ex-Pearson developer, bassist, and AI enthusiast. Both quit their jobs to build pluginmaker.ai full-time.

We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant. *** Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
