**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Talk by Todd Nussbaum LGTM is not a Strategy Pull requests are where quality is won or lost, and too many teams still treat reviews with a rushed "LGTM". In this talk, you'll learn a practical, repeatable approach to high-quality PR reviews that balances speed with risk management - covering how to triage changes quickly, review in layers, and write comments that lead to better outcomes without friction. We'll also show how QA and developers bring complementary lenses to the same review, turning acceptance criteria, scenarios, and observability into shared responsibility instead of production surprises. You'll leave with a lightweight framework and concrete habits for authors and reviewers that make reviews faster, kinder, and more effective. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park! If you can, please sign up via meetup by noon the day of the meeting so we can have an estimate headcount for food :) We always order extra, so feel free to join us even if you don't get signed up! Thank you to Bold Penguin for providing the food and location! **Parking & Arrival:** **Parking:** Parking in Bridge Park is free. The closest lots are the Mooney Garage and the Hotel/Endres Garage. **Entry:** The doors to the office are to the right of PINS. The street level door and elevators lock at 6pm.

Once you exit the elevator, turn right. \*\*\* We are a bunch of professionals, students, and geeks who are excited about Ruby programming language ([http://ruby-lang.org/](http://ruby-lang.org/)) and Rails framework ([http://rubyonrails.com/](http://rubyonrails.com/)) and the joy they have brought back to web development. Our main goal is to share the love of the Ruby and Rails ecosystems with anyone that is interested. We cater to everyone, whether a non-programmer through advanced Rubyists. * We give lectures on programming topics * We freely provide decades worth of experience * For full details of this month's meeting please visit [http://columbusrb.com](http://columbusrb.com)

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

**Karaoke Night**: Bring your glee club friends. Enjoy a flashback to your choir days. No chorus line. It's all you baby. Sing. Shout. Scream. Lip sync if you need to. But do show up and do have a good time. **On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours. **Glasses**: …will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass! **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host*

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

**💙 Live Video Speed Dating with Toledo Locals — Real People** Once on Zoom, you'll go through host-managed one-on-one rounds with people from Toledo sorted by age and compatibility, as a skilled host keeps the pace natural. On completing your sign-up, you submit a short personality questionnaire — the matching data comes from to give you a personally matched Toledo lineup, meaning your rounds are curated and not random. Once the event finishes, your mutual matches are disclosed — but only if the feeling was mutual — and you reach out whenever you are ready. **Register under your age group:** - **Ages 18-32** → [REGISTER HERE](https://tempodating.com/product?productId=532.0&productType=onlineSpeedDating&city=Toledo&groupurlname=club-for-serious-connections-day-trips&ar=18-32&face_v=4.0) - **Ages 30-46** → [REGISTER HERE](https://tempodating.com/product?productId=532.0&productType=onlineSpeedDating&city=Toledo&groupurlname=club-for-serious-connections-day-trips&ar=30-46&face_v=4.0) - **Ages 40-58** → [REGISTER HERE](https://tempodating.com/product?productId=532.0&productType=onlineSpeedDating&city=Toledo&groupurlname=club-for-serious-connections-day-trips&ar=40-58&face_v=4.0) - **Ages 55+** → [REGISTER HERE](https://tempodating.com/product?productId=532.0&productType=onlineSpeedDating&city=Toledo&groupurlname=club-for-serious-connections-day-trips&ar=55+&face_v=4.0) **⚠️ RSVP is not enough:** Clicking rsvp does not complete your registration, so use the link for your age bracket above, sign up, and finish the short personality quiz — places are capped so do this promptly, and your spot is held only when both steps are done. --- **Ideal if you are:** - People based in Toledo moving beyond apps that waste evenings for no return and want to talk to real people tonight. - Anyone throughout Toledo who are tired of matches that fade out before meeting and want actual face-to-face conversation. - Singles across Toledo who are tired of endless scrolling and zero real dates and are after something more than a swipe can offer. - Someone around Toledo ready to move past matches that ghost after two messages and are looking for real connection. - Anyone across Toledo moving beyond the app treadmill that goes in circles and want to talk to real people tonight. **Your four steps** 1. **Find your age group** – using the link for your age bracket, then take the brief quiz, since your spot is held only once this is done. 2. **Open the call** – by clicking the Zoom invite at the event time, works on any modern device with a camera, and from there a live host guides everything. 3. **Connect** – quick private video rounds with Toledo singles curated for you by age and personality, while the host controls the pace so you can relax, since every person you meet was matched to you on purpose. 4. **Learn your results** – we share mutual match results after the session closes, since only mutual matches exchange details and everything else stays private, and you are in control of everything that happens next. --- ✨ Try something that actually works — sign up through the link above and everything else is sorted whenever you are set. Your next chapter might start tonight. 🌸 ✨
