Dynamic Programming

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life.

We'll meet at Wyandot Park, cross Riverside Dr at Lane Rd, then walk south along the water to Griggs Park and back — around 5 miles total. A scenic out-and-back route along the Scioto River. One of the nicer stretches of trail in Columbus. Parking is available at Wyandot Park, off Lane Rd. Here's an overview of the route on Google Maps: https://maps.app.goo.gl/uqweEoi6vcpY4esTA See you there.

Posting this early because seemingly all Sundays in May are holidays or busy! I picked a shorter thriller that's hopefully a fast read/listen. [Columbus library link to book](https://cml.bibliocommons.com/v2/record/S105C3458940) Location: Grandview Cafe, *1455 W. 3rd Ave*, Columbus, OH 43212 [Menu](https://www.grandviewcafe.com/menu) Book summary: Daniel leads a rich life in the university town of Athens, Georgia. He's got a couple close friends, a steady paycheck working for a regional airline, and of course, for a few glorious days each Fall, college football tailgates. He considers himself to be a mostly lucky guy -- despite the fact that he's suffered from a debilitating disease since he was a small child, one that has left him unable to speak or to move without a wheelchair. Largely confined to his home, Daniel spends the hours he's not online communicating with irate air travelers observing his neighborhood from his front porch. One young woman passes by so frequently that spotting her out the window has almost become part of his daily routine. Until the day he's almost sure he sees her being kidnapped.

⚠️ **IMPORTANT: You must sign up and buy a ticket here to attend:** [https://groupvibe.com/](https://groupvibe.com/) **Join the Columbus City Brunch Club and make new friends!** Each meetup brings together 4–6 people for casual conversations over brunch. We use the Groupvibe platform to facilitate the meetup and ensure everyone’s a good fit. 👉 **To attend, you’ll need to complete registration via this link:** [https://groupvibe.com/](https://groupvibe.com/) We’ll share the exact location of the upcoming meetup the night before only if you have bought a ticket or membership plan. **Why this works:** \* Smaller groups make real conversations easier. \* Discover new restaurants in your city, together. \* Curated lunch venues with good food and vibe. \* If you hit it off with your group, there’s plenty of time to hang out afterwards. **Note:** RSVPs on Meetup don’t reflect total attendance.

We will meet next to the restrooms at the [Big Meadows Picnic Area](https://www.metroparks.net/wp-content/uploads/2022/06/HBK_Web_1980.png). They're all the way at the back of the park, and they can be found at coordinates [40°09'06.6"N 83°02'30.2"W](https://www.google.com/maps/place/40%C2%B009'06.6%22N+83%C2%B002'30.2%22W/@40.151828,-83.0423587,214m/data=!3m2!1e3!4b1!4m10!1m5!3m4!2zNDDCsDA5JzA4LjAiTiA4M8KwMDEnNDUuMSJX!8m2!3d40.1522222!4d-83.0291944!3m3!8m2!3d40.151827!4d-83.041715?entry=ttu&g_ep=EgoyMDI0MTIwNC4wIKXMDSoASAFQAw%3D%3D) (near the playground and the zip line). We'll hike about 5 miles at [Highbanks Metro Park](https://www.metroparks.net/parks-and-trails/highbanks/) on the Dripping Rock and Overlook Trails. Afterward, we'll head over to [Olentangy River Brewing](https://www.olentangybrew.com/) for drinks, coffee, or food (their Sunday [food truck](https://www.olentangybrew.com/eventsandfood) is Venezuelan and always gets good reviews). The actual address of the brewery is [303 Green Meadows Dr S, 43035](https://www.google.com/maps/place/303+Green+Meadows+Dr+S,+Lewis+Center,+OH+43035/@40.1551938,-83.0144045,17.25z/data=!4m6!3m5!1s0x8838f395cef06c97:0xe407de61b3e30069!8m2!3d40.1551765!4d-83.0124352!16s%2Fg%2F11c26jc7j9?entry=ttu). If you can't make the hike, we should be there by noon. **How to find our starting point in Big Meadows:** If you are new to Highbanks, the Big Meadows picnic area is 1.5 miles into the park just after you turn into the park off of U.S. Route 23. That is, after you enter the park, drive a mile and a half into the park. You will come to a crosswalk with a yield sign in the middle of it (this is not to be confused with the first such crosswalk you come to just in front of the Nature Center, which you arrive at maybe a quarter of a mile into the park). Just after this second crosswalk, make a left. Then make another almost immediate left into the parking lot on your left. There you will see the jungle gym and the kiddie zip line to your left. I will be just in front of the restrooms just a bit further down from the jungle gym and picnic shelter; the restroom building will also be on your left.

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

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!
