**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Jonathan Stevens **Polymorphic Association - The Good, the Bad and the Ugly** When Active Record works, it’s great. Polymorphic associations in Active Record promise elegant flexibility: one interface, many possible models. When they work, they feel almost magical. But when your application grows and real‑world complexity sets in, that magic can quickly turn into confusion, broken queries, and performance headaches. We’ll explore where polymorphic associations shine, where they silently introduce technical debt, and why even experienced Rails developers can end up wrestling with unscoped queries, tricky joins, and hard‑to‑optimize relationships. We’ll walk through real examples of tangled polymorphic logic—and more importantly, show practical strategies to refactor, untangle, or even avoid these pitfalls entirely. By the end, you’ll know when to reach for polymorphism, when to run away from it, and what to do when your complex query simply refuses to cooperate. **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!

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. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. 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. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Let’s try some Filipino food at a well known Grandview area restaurant, This is the menu: https://www.canva.com/design/DAHByDNxwDA/TO8oxEmjQrBp_PP_mLPUag/view?utm_content=DAHByDNxwDA&utm_campaign=designshare&utm_medium=link2&utm_source=uniquelinks&utlId=h435abfbbb3#1

***Okay, call me crazy but you have got to try their chip n dip!*** Club 185 is a true hidden gem in German Village! Seriously, old school, good comfort food and drink. We will try to gather in spaces near the windows. While we'll share Chip n Dip, you'll want to order a sandwich, too. **Where the Chip Began (1817)** Potato chips can be traced back to an English chef, William Kitchiner, who includes ‘crisps’ in his bestselling cookbook, “The Cook’s Oracle.” **Chip and Dip Popularity** The popularity of chip and dip skyrockets at the end of World War II with new entertainment fads and the introduction of Lipton’s new advertising campaign for their famous French Onion Dip. (Club 185 doesn't openly admit it, but I'm pretty sure that's their dip recipe!) **[Club 185](http://club185.com/)**—a true neighborhood bar serving since 1954, when it was known as a local 'speak-easy'. Located in German Village, Club 185 features a menu of quality casual comfort food and full bar. From politicians to lawyers, hardhats to hipsters—all find Club 185 the perfect place to tame their hunger and quench their thirst! **PARKING**: I know, brick street parallel parking can be a pain. Two other choices, metered parking along Livingston heading towards Children's Hospital or across the street in the large church lot (park in spaces farthest away from the church entrance doors, closer to the street). **PRE-EVENT**: **HAPPY HOUR (3-5pm)**: Italian drinks and bites at [Cento's happy hour](https://centogermanvillage.com/menus/), nearby.

Dance with us in the afternoon then you can still go out in the evening! **Sponsor: All Soles Contra and Square Dancing, First Unitarian Universalist Church, 93 W. Weisheimer Rd., Columbus OH 43214** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 1:30 - 2:00, followed by dancing 2:00 - 430. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. Please bring your own refillable water bottle.
