Welcome to **Execution with Style**, a weekly co-working lab for freelancers, creators, founders, and builders who want structure, accountability, and real momentum. We combine **deep focus + small-group pressure + a playful self-expression twist**. When we wear something unusual, we step outside our normal identity. That’s when creativity becomes easier. 📲 **Want reminders or to connect with others before/after?** Join our [WhatsApp group](https://chat.whatsapp.com/K6LidaoQhe16wZ0Se9pNM6), Keep contact via [Instagram](https://www.instagram.com/nocrastinationclub/) **Execution with Style** 👗🧥✨ Each session, you’re invited to wear **clothes that you don’t normally wear**. Something expressive. Something bold. Something unusual. **Examples:** * the jacket that never leaves your closet * something colorful or dramatic * something funny / absurd * something you “could never pull off”… until today No pressure — but if you join in, be ready to share the story behind it. **Self-expression + execution = momentum.** **Location** * Our weekly co-working sessions take place at creative, cozy hotel lobby **Jaz in the City in central Vienna**. * Regular participants may also be privately invited to occasional **Skyscraper Secret Sessions** — spontaneous small-group co-working gatherings at a private skyline location with **free tea & coffee**, plus **gym and shower access**. * These special sessions are **invitation-only** and shared privately with regular members of the community. 🕐 **Time**: 1:00 PM – 5:00 PM Every Tuesday 📍 **Location**: Jaz in the City – Ground Floor Lounge: Windmühlgasse 28, 1060 Vienna, Austria 💻 **Bring**: Your laptop, journal, creative tools, or anything you’ve been procrastinating on 🌿 **Hosted by**: NoCrastination.

**Walk & Talk** Willst du auch mehr Bewegung in dein Leben bringen? Und dich dabei noch gut unterhalten, so dass die Zeit verfliegt? Dann bist du hier genau richtig, denn mir geht es genauso. Alleine ist langweilig und die Zeit vergeht nicht, daher hab ich mir Walk & Talk überlegt. Inspiriert wurde ich durch die Walk & Talk Gruppe in Hamburg, wo ich mehrere Male dabei war als ich in Hamburg lebte. Unterschiedliche Menschen treffen sich einmal in der Woche für einen flotten Spaziergang und unterhalten sich dabei. Ich liebe es neue Menschen kennenzulernen und auch bekannte Gesichter wiederzusehen, dann geh ich ganz nebenbei und das macht auch noch Spaß.😊 **Walk:** Wir brauchen einfach regelmäßige Bewegung und ich weiß selbst, wie schwierig es ist, diese in den Alltag zu integrieren. Deshalb ist dieser Walk genau richtig. Nach diesem Spaziergang fühlst du dich einfach wohl, fit und entspannt. **Talk:** Das Reden kommt ganz von selbst beim Gehen. Du kannst über alles reden, egal, ob privates oder berufliches, alles was sich ergibt ist willkommen. Und wenn du keinen Bock aufs Reden hast, dann gehst du alleine, auch das ist völlig in Ordnung. **Wie das ganze abläuft:** * Die Teilnahme ist völlig kostenlos. * Wo: U6 Spittelau (im Freien), Richtung Donaukanal, Ausgang Josef-Holaubek-Platz, direkt vor dem Fernwärme-Turm (https://maps.app.goo.gl/XwAayz4FQe2EW8WK9) * Wann: Wir treffen uns dienstags um 13 Uhr, egal, ob bei Regen, Sturm und Kälte oder bestem Sonnenschein – Walk & Talk findet nahezu JEDE Woche statt außer ich bin mal im Urlaub. * Wir starten pünktlich und beginnen mit einer kurzen Vorstellungsrunde. * Wie gehen am Donaukanal entlang von Höhe Spittelau bis zum Schwedenplatz und zurück. * Ca. 7 Kilometer sind wir unterwegs und unterhalten uns dabei mit interessanten Menschen. Dabei kannst du neue Bekanntschaften schließen, dich inspirieren lassen, von Projekten erzählen oder einfach nur smalltalken und die frische Luft genießen. Alles ist erlaubt. * Nach ca. 1,75 Stunden sind wir wieder am Ausgangspunkt zurück. * Bei einer Teilnahme von über 5 Personen gehen wir in Paaren und wechseln diese alle 10 Min. Wenn du aber lieber alleine gehst, ist das auch vollkommen in Ordnung. * Für alle, die einfach mal etwas Neues ausprobieren wollen. **Bist du bereit?** Dann komm mit! **Start bei U6 Spittelau Ausgang Donaukanal** Nochmal: um **PUNKT 13.00 Uhr dort sein**, denn **nach kurzen Vorstellungsrunde gehen wir gleich los. Sei pünktlich, denn die Gruppe wartet nicht.** Du musst nichts vorbereiten oder dich gar anmelden, komm einfach vorbei. Ausreden gibt es nicht. Geh mit und freu dich auf eine tolle neue Erfahrung. **Wer macht es?** Ich bin Marie Meyer-Marktl und Ideengeberin, Host und Organisatorin von Walk & Talk. Ich unterstütze seit 2019 Menschen dabei Freude ins Arbeitsleben zu bekommen und bin Business und Life Coachin. „Strahle, wenn du an deine Arbeit denkst“, ist meine Vision für jedermann und jedefrau. Privat merkte ich, dass ich endlich wieder mehr Bewegung brauche – und das klappt am besten gemeinsam mit anderen Menschen. Sei dabei bei Walk & Talk und bring Bewegung in dein Leben. **Do you speak English? Then welcome to Walk & Talk!** This event is suited for all people who like to connect to other people and like to walk. The beauty of this regular event is that you are in the nature and you walk around 7 kilometers. In the meantime, if you feel for it, you talk, if not, you just walk. You do something for your health, get to know new people and you will feel much better. It’s FREE, all you need to do is to show up this Tuesday at no later than 1 pm at the U6 Spittelau exit to Donaukanal.

**Finally!** The first **PostgreSQL Meetup in Vienna** is coming up! Exciting talks and networking opportunities around PostgreSQL are waiting for you. Meet fellow Vienna-based and international PostgreSQL enthusiasts at this meetup and take the opportunity to connect locally and exchange ideas. **When:** March 18, 2026 — 6:30 PM to 10:00 PM **Where:** [Dotbite](https://dotbite.at/) GmbH, Barichgasse 38/1/6, 1030 Vienna **Preliminary Agenda:** 6:30–7:00 PM — Doors open & registration, networking 7:00–7:15 PM — Welcome & opening 7:15–7:30 PM — Sponsor introduction: Dotbite 7:30–8:05 PM — Stop Guessing, Start Indexing: A Developer’s Guide to Database Indexes (by Rajeet Kumar) 8:05–8:15 PM — Break 8:15–8:50 PM — Is your PostgreSQL truly Cloud(native)? (by Jan Karremans) 8:50–9:00 PM — Break 9:00–9:20 PM — pgcov: Bringing Real Test Coverage to PostgreSQL Code (by Pavlo Golub) 9:20–9:30 PM — Closing 9:30–10:00 PM — Networking & snacks \*\*\*\*\* Session Details \*\*\*\*\* **Speaker 1:** Rajeet Kumar **Title:** Stop Guessing, Start Indexing: A Developer’s Guide to Database Indexes A lot of developers know that indexes make queries faster, but many don’t know why, when an index will actually be used, or why some queries ignore them completely. In this talk, we open that black box. We build a mental model of the B-Tree, the structure used by most databases for their default indexes, and look at its internal layout. Using that model, we’ll explore where B-Tree indexes shine, where they fail, the costs associated with them, and how selectivity affects whether an index is used. Finally, we’ll briefly look at practical techniques such as covering indexes and functional indexes. **Speaker 2:** Jan Karremans **Title:** Is your PostgreSQL truly Cloud(native)? As organizations modernize their platforms with containers, Kubernetes, CI/CD pipelines, and microservices, databases are often the last piece to truly transform. Simply lifting and shifting PostgreSQL to a cloud VM does not automatically make it cloud-native. So what does? We’ll cut through the buzzword bingo and examine what they mean for PostgreSQL in real-world environments. Drawing from decades of database experience and years running PostgreSQL in Kubernetes, this session highlights how cloud-native principles such as automation, resilience, observability, and rapid redeployment reshape the way developers and DBAs collaborate. Whether you are a developer, DBA, architect, or decision-maker, this talk will help you assess where you stand today and what it takes to make PostgreSQL a true enabler of speed and innovation in modern cloud environments. **Speaker 3:** Pavlo Golub **Title:** Bringing Real Test Coverage to PostgreSQL Code **Abstract:** https://posetteconf.com/2026/talks/pgcov-bringing-real-test-coverage-to-postgresql-code/ \*\*\*\*\* Snacks and drinks will be provided. A big thank you to [Dotbite](https://dotbite.at/), our main sponsor, for hosting us and providing food and drinks! 🚨 **Attention: Limited spots available!** 🚨

## **Advanced-Online-Training “Beziehungs-Tabus” (2 Stunden) Vertiefungstraining für erfahrene Teilnehmer. 6 Teilnehmer.** ## In diesem Training erweiterst Du deine Fähigkeit befriedigende Beziehungen mit anderen Menschen zu erzeugen. [=> Melde Dich hier an](https://www.eventbrite.de/e/radikale-ehrlichkeit-advanced-session-online-deutsch-tickets-1983449509877?aff=Meetup) **Wie funktioniert dieses Training praktisch?** Du sprichst genau aus, was Du deiner Mutter\* früher nicht sagen durftest. Wahrheiten, die in deiner Familie als tabu und gefährlich galten. Genau das, was Du am wenigsten zugeben möchtest. Themen wie -Wünsche nach Nähe und Aufmerksamkeit oder Distanz und Ruhe -Schwierige Gefühle wie Wut, Abscheu, Trauer und Angst -Freude, Lebendigkeit und sexuelle Erregung -Urteile, Bewertungen und innere Reaktionen Du benennst auch Deine Erwartungen und Kontrollstrategien.

Immer wollte ich alles richtig machen. Bloß nicht enttäuschen!“ Erst durch Radikale Ehrlichkeit konnte ich Unsicherheit und Schuldgefühle hinter mir lassen – und beginnen, die Abenteuer, Beziehungen und Lebensfreude zu erfahren, die Disziplin, Strategien und Rollen nie bringen konnten. > **„Ich möchte inspirieren und zeigen, wie einfach tiefe Beziehungen sein können – und wie großartig sich ein Leben ohne Maske anfühlt.“** Christoph Fink ist Gestalt- und Traumatherapeut in München und arbeitet mit Methoden wie Somatic Experiencing (SE) und Emotionsfokussierter Therapie (EFT). Als Radical Honesty Trainer (zertifiziert 2017 durch Dr. Brad Blanton) begleitet er Gruppen, Einzelpersonen und Paare. 2022 gründete er mit Freunden das Radical Honesty Institut, um eine neue Generation von Trainern auszubilden. **[radikaleehrlichkeit.de](http://radikaleehrlichkeit.de)**

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
