These technologies are integral to numerous sectors such as manufacturing, energy, transportation, medical, and utilities, where they play a crucial role in the operation and management of physical processes. As OT systems become more interconnected and integrated with Information Technology (IT) networks, they face increased vulnerability to large-scale cyber attacks. This integration, while beneficial for operational efficiency and data sharing, exposes OT systems to the same cyber threats that typically target IT environments. The goal of the OWASP OT Top 10 is to raise awareness about the top security risks and vulnerabilities specific to OT environments. **Speaker:** **Siegfried** **Hollerer** has seven years of experience as a penetration tester, focusing on the analysis of web applications, IT/OT infrastructures, and social engineering attacks. In addition to his practical experience, he has obtained an OSCP certificate. Furthermore, Siegfried has gained experience in incident response. During this time, he also carried out security management consultations, audits and certifications based on the OT security standard IEC 62443 and the IT security standard ISO 27000. In 2023, Siegfried joined the Federal Ministry of the Interior (BMI) in Austria as a security architect and analyst to enforce the “Netz- und Informationssystemsicherheitsgesetz” (NISG), which is the national implementation of the NIS EU directive [cf. Directive (EU) 2016/1148] . **Talk 2: "Recurring Security Pitfalls in Cyber-Physical Systems: A Cross-Domain Analysis"** Cyber-physical systems (CPS) repeatedly exhibit similar security weaknesses across domains, despite differing technologies and operational contexts. This talk explores recurring security pitfalls in areas such as manufacturing, energy, and aerospace. By analyzing common patterns, we reveal the root causes and discuss strategies for designing more resilient CPS architectures and engineering practices. **Speaker:** **Matthias Eckhart** is a postdoctoral scientist at the AIT Austrian Institute of Technology. Previously, he worked on privacy and responsible AI at Amazon, conducted security research at SBA Research, and developed software at NXP Semiconductors. **Philipp-S. Vogt** is a research engineer and PhD candidate at AIT Austrian Institute of Technology. Vogt received a MSc in electrical engineering from TU Wien. His research interests include cyber-physical systems, embedded systems and cyber security.

**ACHTUNG! Wir treffen uns dieses Mal auf Grund von Bauarbeiten bei der U4 Station Friedensbrücke Ausgang Straßenbahn 5 und 12!!!** *This week's event will be hosted by Sridhar (Srinivasan) one of our regulars, who is rediscovering the joy of being in nature and in community. He enjoys the stimulating interactions that arise from new connections while walking, and hopes that others also find their spark and are moved to flow, that eventually fulfills them.* **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.

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.

Donations optional. **🪑Seating information:** * If this is your first time joining us, please look for **Joanna Liu** when you arrive at the **Ground Floor Bar** (not at the hotel reception). * There is a **long table with 12 seats** for those joining the **peer accountability session** — please arrive on time if you’d like to sit here. * There are also **round tables nearby** for anyone who prefers a more flexible setup. * If you’d like to **work independently (without the Pomodoro arrangement)** but still be part of the group energy, just let Joanna know — we’ll make sure you’re comfortably included. 💛 🌱 **What to Expect** * **Drop in anytime** between **1:00–5:00 PM** — stay for a bit or settle in for the whole session * **Clarify your goals**: write down your measurable tasks for the day on a Post-it when you arrive * **Two spaces**: one for quiet focus, one for casual conversation. After each focus session, if you’re still in the flow, feel free to remain seated — no need to move. If you're up for a chat, join others in the social area for a relaxed break. * **Social start**: from **1:00 to 1:28 PM**, we mingle and get to know each other; our first focus session begins at **1:30 PM** * **Gentle structure**: we begin with a soft check-in and intention round * **Pomodoro-style rhythm**: We work in 45-minute focus blocks followed by 15-minute social breaks. If 45 minutes feels too long, feel free to break it into two 20-minute focus sessions with a short 5-minute reset in between. You’ll need to self-regulate these shorter cycles, just tune into your own flow and rejoin when ready. * **Quiet companionship**: no pressure to talk during focus time — just shared presence and support * **Welcoming space**: we meet in the creative, cozy lobby of the **Jaz in the City** 💡 **New to Pomodoro?** Don’t worry — we’ll guide you gently. No apps or timers needed. **Who This Is For** You’ll enjoy this if you: * want real accountability (not just a desk) * have a project, goal, or task you’ve been procrastinating on * like focused work blocks with a supportive vibe * are building something (job search, freelancing, creative work, admin, studying, side project, etc.) 💬 Why Join? * Beat procrastination with gentle accountability * Reclaim your momentum without doing it alone * Enjoy a change of scenery that boosts your focus **Group Size:** This is designed as a **small execution lab** (limited spots) to keep the energy focused and the accountability real. Bring your project. Bring your presence. Let’s work side-by-side. 💚

Things to know before playing: Ladies and Gentlemen, boys and girls; We play Tuesday Night Football (outdoor only) . We play 90 minutes (kick off is at 20:30, and we meet at least 15 minutes before for a warm up phase). Post-Corona football matches are most likely between 14-16 and 28-32 players. If you would like to join please bring artificial turf shoes (like the ones for indoor turf) and shin pads (not mandatory but definitely recommendable). All I ask is that you come with a good mood, be respectful to everyone, and pay online using the link below.

We need to respect current regulations in Vienna, Austria. The main priorities are to have fun and being safe. The drinks are relatively free after the game in the local pub, served to those who have shown fantastic football fair-play skills. We will confirm the location, the pitches, and the dressing room numbers via our dedicated Football WhatsApp group/s. Keep an eye out for the group messages. See you all soon. Sorin SMS/ WhatsApp +43 6764276984 (please ask to be added to our football groups). We will probably need to confirm your presence if you are coming for the first or second time. Important management rule: **\> "No shows" are penalized with 10€ fee\. Please remove your name from the list at least SIX\!\!\! \(6\) HOURS before the event\.** Book a place via FootballExperiences.NET using this link [FOOTxp](https://footballexperiences.net/kickaball/) One small final note: Please avoid trying to take justice in your hands. If someone is talking bad, complaining, insulting someone, fouling on purpose or committing the usual football shenanigans, please let the organizers know. Measures will be taken, we assure you. Any misbehavior on your part, such as responding in an obscene way, fighting, or leaving the pitch is not a practical and diplomatic way of resolving the issues (it tends to create more tension and cause more problems).

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
