Join us in the search for the true, the good and the beautiful. Each meet is in one of two formats: a shared reading and open discussion of philosophical texts, or a continuing series of lectures based on the reading of a fascinating book of philosophy. Both formats are in Hebrew, with some reading of English texts, assisted whenever needed. We meet weekly Friday on 80 Rokach Boulevard, Tel Aviv, at the gardens of the Council for a Beautiful Israel. Welcome anyone interested in understanding life more deeply, regardless of age or prior knowledge. The love of wisdom is enough. Please join our WhatsApp group: https://chat.whatsapp.com/JeAa2uRNTlF0rdrVTLzUC0?mode=wwt Note: there's always enough sitting room, but some of it is on the grass or a mat on the floor. If you want to guarantee yourself a chair, please bring one with you. Sapere Aude! (Kant's Motto: Dare to Think!)

Come see why the most powerful tool in your stack is likely the one you’re already running. ## ​\*\*[Nadav (Kremer) Beker](https://www.linkedin.com/in/nadav-kremer/overlay/about-this-profile/) \|\*\* Tech Lead at **Finonex**\| **How Observability Killed My Performance** ​Logs, traces, metrics, correlation IDs — observability promises clarity when systems get complex. But in Node.js, these tools are not free, and used without care they can become a serious performance bottleneck. In this talk, I’ll share real-world lessons from production Node.js systems where adding observability actually degraded performance. We’ll look at the hidden costs of logging, async logging, AsyncLocalStorage, distributed tracing, and high-cardinality metrics — and why these issues often only appear under real load. ​ ​-------------- Kindly be informed that attendance at the meetup is on a first-come, first-served basis until capacity is reached.

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. For our full event schedule, visit [https://shutupwrite.com](https://shutupwrite.com). **Other Important Details:** WiFi name/password: TBD Venue Guidelines: Please thank our hosts by purchasing something.

We have referrals for you! All visitors are welcome. Any questions contact [pmarchio@farmersagent.com](mailto:pmarchio@farmersagent.com)

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

Join the Columbus AI community for our quarterly gathering — a casual, community-focused evening where everyone has a chance to share, learn, and connect. These open mic–style events give anyone in the community up to **5 minutes** to present a project, share a tool, pose a question, or offer a perspective on the evolving AI space. No slides required — just a welcoming space to exchange ideas and keep the local AI conversation moving. If you’d like to take the stage, message **Chris (the organizer)** with a **title and short description** of what you’d like to share. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)

**NEW LOCATION: Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: * 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. * 6:30 to 8:00 pm. Main meeting and presentation(s). Lonnie Morgan will be presenting information about the DLT Library. "The Python library `dlt` provides a powerful [REST API toolkit](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api/basic) to ingest data. Combined with our [LLM scaffolds](https://dlthub.com/workspace) and [MCP server](https://dlthub.com/docs/hub/features/mcp-server), you can build a custom connector for any of the 8k+ available sources in 10 minutes by following this guide. Building with LLMs is an iterative process. We will follow this general workflow and give practical tips for each step." See Our [Parking Map](https://docs.google.com/presentation/d/1u2A4fLNlxwLJn0KA_hKc8bnFlFHLvsHBDh-_8wzX_tk/edit?usp=sharing) We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact centralohpython@gmail.com
