**Hey fellow AWS enthusiasts! ✨** This April we welcome **[Philipp Hoyer](https://www.linkedin.com/in/philipp-hoyer-621555174/)**, Lead Engineer at Rackspace Technology. He'll walk us through a journey of AWS' popular containerization services Amazon ECS and Amazon EKS running on Fargate by discussing which fits best for which use case, where EKS can make you go nuts and when ECS might shines brighter - or vice versa. **📆 Tonight's Agenda** 19:00 - Welcoming **19:15 - Talk by Phillip** 20:15 - Networking Thanks to our friends at **[CodeCam:N](https://www.codecamp-n.com/)** who open their offices for us and sponsor food and drinks for this evening. Looking forward to seeing you 👋🏻 Nora & Frank \-\-\- The talk ⤵️ **An AWS Container Journey - The Good, The Bad and The Ugly featuring ECS and EKS** EKS on Fargate promises fully managed Kubernetes with zero node management—but the reality is often more complex than expected. This talk explores the journey of building a production workload on EKS Fargate, starting with the initial motivations and architectural decisions. It uncovers three non-obvious pitfalls that only surface during real-world implementation, including challenges with load balancing, EFS integration, and logging. For each case, the underlying issues and the required workarounds are dissected to reveal the hidden operational complexity behind the “serverless” promise. Based on these insights, the talk takes a critical look at whether ECS on Fargate would have been the simpler alternative. It provides a concise overview of ECS, highlights its own limitations, and delivers a direct comparison between ECS and EKS. The session concludes with clear, experience-driven guidance on when to choose which service—helping teams avoid costly assumptions and make better architectural decisions in AWS container environments. The speaker⤵️ Philipp is a Lead Engineer at Rackspace Technology who enjoys turning complex cloud architectures into solutions that actually work in practice. He started in software development, moved through the DevOps world of pipelines, containers, and Kubernetes, and eventually specialized in AWS. He has built and operated cloud solutions ranging from big data and streaming platforms to containerized and serverless workloads. With experience in both insurance and automotive, his focus today is on real-world cloud challenges—especially the ones that don’t show up in the docs.

Speaker: **Hrvoje Novak, Anita Banjac,** **LARES - Laboratory for Renewable Energy Systems - FER** Title: **Python as a Research Workhorse: From Data to Optimal Control in Smart City Systems** Python is often seen as a glue language for automation and data analysis, but in research it becomes a powerful platform for modeling, optimization, and control. We show how it is used to build advanced decision-support and control algorithms for large-scale technical systems – starting from real-world measurements and nonlinear system models, we move through machine learning and optimization-based control, illustrating how these pieces come together in real smart city applications. We will take a behind-the-scenes look at how advanced control solutions are built, tested, and deployed in complex, real-world systems. \-\-\-\-\-\-\-\- We are in for a treat! Join us on **Tuesday** at MaMa to hear researchers from FER share their experiences from projects they did with industry partners solving real-world problems on a scale. Drinks and friendly discussion afterwards at [Old Pharmacy Pub](https://maps.app.goo.gl/AeaRdnBrMqPiRhvPA) 🍻🍷🥤☕️

This month's prompt concerns the idea of the “warrior philosopher” (seemed appropriate in these times)--that is someone whose understanding of violence, power, and justice is forged through direct experience of war. We are looking at Major General Smedley D. Butler, a highly decorated U.S. Marine raised in a Quaker (pacifist) tradition who later became a prominent critic of American militarism (there is a wonderful biography of Gen. Butler called "Gangsters of Capitalism") Butler's argument in *War Is a Racket* (1935): that many U.S. interventions were driven less by national defense than by corporate and financial interests, with Butler portraying himself as an enforcer for business and Wall Street. We can consider the moral ambiguity of his insider critique—whether complicity strengthens or undermines credibility and also consider some of the concrete reforms he proposed (e.g., “conscript” capital before soldiers, restrict the military to coastal defense, and have only those who fight decide on war). Butler’s life arc clearly changed from pacifist upbringing to warrior to antiwar crusader—and asks whether true understanding of peace requires firsthand knowledge of war, and what that implies about the cost of suffering. So do we need to suffer to understand suffering? Do we have to experience war to appreciate peace? As one more question: in the movie "A Few Good Men" Jack Nicholson's character says that "you have the luxury of not knowing what I know" so do most of us go through life oblivious to real violence and suffering? See you at Drunken Philosophy!

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
