We've got 2 brilliant lectures on real production case studies on reducing memory footprint by order of magnitudes. One from DoubleVerify, using hackie but efficient data structures, and the other from Next Insurance with 4 real world methodologies shown on stage. Thanks to **DoubleVerify** for sponsoring and hosting the event! **AGENDA** 18:00–18:30 **Mingling, food, and drinks** 18:30–18:40 **Opening words** 18:40–19:25 **Beautiful Code Is Overrated: How "Ugly" Engineering Saved Geo at Scale / Alex Cherny - DoubleVerify** 19:30–20:15 **Bulletproof Cookbook to Reduce Your Service's Memory** **/ Haim Yadid - Next Insurance** **Beautiful Code Is Overrated: How "Ugly" Engineering Saved Geo at Scale** We often celebrate clean, elegant architecture, but when data grows 30× overnight, beauty doesn't keep the lights on. This talk walks through a real-world case study of how the Geo traffic service at DoubleVerify broke under 500M IP ranges and how a brutal, byte-level approach outperformed every elegant solution. I'll share the challenges, trade-offs, and the unconventional design choices that helped us slash ramp-up time from 70 minutes to under 3 and memory from 193GB to 13GB. Sometimes, "ugly" is what scales. **Alex Cherny / DoubleVerify** Alex Cherny is a Director of Software Engineering at DoubleVerify, where he leads large-scale Traffic systems operating at millions of requests per second. He has extensive experience building and optimizing JVM-based distributed systems under strict latency, memory, and reliability constraints. Alex focuses on pragmatic performance engineering and believes that clean abstractions are valuable—until scale forces you to break them. **Bulletproof Cookbook to Reduce Your Service's Memory** In recent months, I’ve been working on a Java service that constructs and processes large in-memory object graphs. The memory consumption has become substantial. As a result, through a systematic analysis and targeted optimizations, I have managed to cut the memory footprint by more than 60%. Leading to cost reduction. In this session, I’ll guide you through the journey - from identifying the memory issues using Eclipse MAT to implementing practical optimizations that led to these savings. You’ll learn how to apply similar techniques to your own services to reduce resource usage and improve performance. At the end of the talk, I will also mention several optimizations that improved runtime performance by a factor of 4. **Haim Yadid / Next Insurance** A software engineer with over 30 years of experience in various technology fields: software development, team management, software architecture, HPC and algorithmic research. In my day job I work in Next Insurance as an engineering fellow where I am involved in numerous cross R&D strategic projects. Before that has been focusing for 8 years on Java platform performance optimization as an independent consultant and was involved in more than a dozen optimization projects. I am a Java Champion and one of the founders of Java.IL, the Israeli Java user group. **FOOD** Light food, light drinks, and beer will be served courtesy of **DoubleVerify**. **RECORDING** We are recording, as always, this meetup and uploading it to our YouTube channel (be sure to subscribe), but please keep in mind asking questions about stuff you don't understand is only possible when you attend the live event. **ADDRESS** Alon Tower 2, Yigal Alon 94, Tel Aviv Floor 27

Join us for some focused writing time. All writers and all experience levels are welcome and don’t worry, no one will see what you've written. This session is about getting your writing done and meeting other writers in your area. When you show up, say hello to everyone, grab a drink, and get your writing tools ready. Once you’re all settled, take some time to chat with your fellow writers. Once everyone’s arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session. Afterward, we’ll have time to chat and get to know each other. We often talk about our successes and challenges as writers. If you don’t have time to stick around, no worries! **A note about the format** We don’t host critiques or readings. These events are a safe space for writers of all skill levels and genres to work on their craft, so no one will read or critique your writing.

The topic for February is "Transitions" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!
