Everywhere else, they're expensive, slow, and painful. We'll show how we collapsed our entire service fleet into a single process — first to replace our mock-heavy tests with fast, real E2E tests that boot every service in-process; then to slash Kubernetes dev environment costs by replacing a pod-per-service with a single pod; and finally to enable fully local development with instant feedback, zero deploy cycles, and real debugging. Same architecture, three wins. ​ **Stav Levinger \| Senior Full Stack Engineer \| Riskified** ​Unblocking the Node.js Event Loop: Real-World Troubleshooting In a NodeJS Consumer ​What happens when a perfectly healthy and robust Node.js service suddenly stops responding, fails its health checks and gets killed by Kubernetes? ​In this talk, I’ll share a real production incident from a high-throughput, Kafka-driven system, where a single consumer began collapsing under unusually large datasets. ​What initially looked like a routine performance issue quickly turned into a deeper investigation: growing lag, stalled processing, misleading signals, and a bottleneck hiding far from where we first looked. ​We’ll walk through the debugging journey step by step, examine practical profiling techniques to narrow down the search, and ultimately uncover the real root cause. ​**Or Kaplan \| Director of Engineering \| Remitly Israel** ​Implementing Distributed locking algorithms in Node.js ​Description ​Protecting shared sensitive shared resources from race conditions is hard enough when running in a single process. Let's make it harder: how do you do it in a distributed system? Scale it up and run it in a production system that serves millions of transactions. See where we’re going here? ​In this talk, I will take you along our journey of implementing distributed locks in Node.js, how they broke, and how we evolved our algorithm over time to support thousands of requests per second in a mission-critical financial system. We will discuss different ways to implement distributed locking, using different tools and approaches. Learn how to improve performance to support more than 10,000 transactions per second which are all trying to access the same resource while running workflows on multiple data centers and how to verify it doesn’t break. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ​​ Kindly be informed that attendance at the meetup is on a first-come, first-served basis until capacity is reached.

The TLV PUG is back! Join us for an afternoon of talks, food, drinks, and good company at Microsoft Reactor Tel Aviv on Level 50 with those incredible skyline views. This time we've got two great talks lined up. Oh, and there will be swag. You're welcome. **Talks:** **From Zero to AI Agent: Building with Microsoft Foundry Agent Service** *[Engin Diri](https://www.linkedin.com/in/engin-diri/) \- Senior Solutions Architect\, Pulumi* AI Agents are everywhere right now, but how do you actually build and deploy one without losing your mind? In this talk, Engin will walk through how to use Microsoft Foundry Agent Service together with the Microsoft Agent Framework and Pulumi to spin up, configure, and manage AI agents, all as code. We'll go from an empty project to a working agent, covering the gotchas and the good parts along the way. **OpenClaw Bots Done Right: No Security Nightmares Included** [Dor Serero](https://www.linkedin.com/in/dorser/) \- Principal Architect\, Microsoft So you want to run an OpenClaw bot, or any agent for that matter. Cool. But have you thought about what happens when things go sideways security-wise? In this session, Dor will share real-world lessons on running OpenClaw bots without the kind of setup that keeps you up at 3 AM wondering if something just went horribly wrong. We'll cover common pitfalls, hardening tips, and practical patterns to keep your bot humming without opening the door to trouble. **Schedule:** * 5:00 PM — Doors open, food, drinks & networking * 5:30 PM — From Zero to AI Agent: Building with Microsoft Foundry Agent Service (Engin Diri) * 5:55 PM — OpenClaw Bots Done Right: No Security Nightmares Included (Dor Serero) * 6:20 PM — Networking, food & drinks * 7:30 PM — See you at the next one! **Where:** Microsoft Reactor Tel Aviv Menakhem Begin Rd 144, Level 50 Tel Aviv-Yafo After the official wrap-up, we'll continue any interesting discussions at a nearby bar for those who want to keep the conversation going.

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.
