MapReduce

SQL Server 2025 delivers a major round of improvements across performance, security, manageability, and hybrid connectivity, and this session gives you a practical, no‑nonsense tour of what matters most. We’ll cover enhancements to the core engine, query processing, storage, and availability that benefit DBAs and developers regardless of where SQL Server runs. You’ll see how SQL Server 2025 aligns with Azure SQL’s roadmap while still supporting strong on‑premises and VM‑based deployments. We’ll highlight new management, monitoring, and troubleshooting capabilities designed to simplify operations and reduce firefighting. AI‑powered features exist in this release, but the focus here is on the foundational improvements you can use immediately. Whether you’re modernizing, maintaining, or planning your next upgrade cycle, this session will help you understand what’s new and how to prepare your environment and your team.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

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.

**How to take control of your subconscious and harness its power!** Join us for an eye-opening lecture where the speaker will break down complex ideas in a clear and practical way. You’ll gain insights into: ✅ The true definition of the subconscious ✅ How it generates unwanted emotions ✅ Its real purpose and function ✅ What determines the pressure it exerts on you And the most important topic: **How do you take control of your subconscious!** But this isn’t just another lecture where you sit and listen passively. It’s interactive and engaging—you can ask questions at any time. 📅 Reserve your spot now! Seats are limited, so don’t wait too long to sign up. Location: 1266 Dublin Rd, Columbus, OH 43215 Hosted by the Hubbard Dianetics Foundation

Our January program is privileged to have Kristen Tregar as our speaker. Ms. Tregar is the co-author with John de Lancie (the actor who portrayed the character Q on Star Trek next generation) of a radio play depicting the events surrounding the Kitzmiller v. Dover Area School District trial. The trial decided the issue of some of the Dover school district board members attempting to insert creationism disguised as "intelligent design" into the 9th grade biology curriculum. She will discuss the trial and the process of writing the play. (Bob Leonhard has seen the play and it is riveting and tense). Ms. Tregar's bio is below: Kristen Tregar is a dramaturg, director, playwright, and theatre teacher. She earned her Ph.D. in Drama and Theatre from the UC San Diego and UC Irvine joint program. In addition, she has a MS in Forensic Science from City University of New York- John Jay College of Criminal Justice and a MA in Educational Theatre from New York University- Steinhardt School of Culture, Education, and Human Development. In 2013, in collaboration with Irish colleagues, she founded *The Ireland Project*, an intercontinental devised theatre work with high school students in New York and Tallaght, Ireland. Her original short story "Far From Here" was recently published in *Stay Awhile Longer: More Scenes From Temecula Valley*. She has two rescued dogs (Kira and Harry) and she rides, competes, and foxhunts with her horses, Andromache and Baker Street Irregular. Food and drinks will be provided at the event.

I don't usually pick romance but I really wanted to do a Hanukkah book. It's a bit on the longer side but hopefully a quick read. The library only has 5 audiobooks so please try to remember to "release it" when you're done. Columbus libraries: [https://cml.bibliocommons.com/v2/record/S105C3503238](https://cml.bibliocommons.com/v2/record/S105C3503238) Location: The Goat Riversouth [219 South High Street, Columbus, Ohio 43215](https://www.google.com/maps?q=219%20South%20High%20Street%2C%20Columbus%2C%20Ohio%2043215%2C%20United%20States) [Menu](https://static1.squarespace.com/static/686d3ed16745133042482c5f/t/68ff654dbb03b96875430bde/1761568077220/all_brunch-20250311.pdf) Book summary: Rachel Rubenstein-Goldblatt is a nice Jewish girl with a shameful secret: she loves Christmas. For a decade she’s hidden her career as a Christmas romance novelist from her family. Her talent has made her a bestseller even as her chronic illness has always kept the kind of love she writes about out of reach. But when her diversity-conscious publisher insists she write a Hanukkah romance, her well of inspiration suddenly runs dry. Hanukkah’s not magical. It’s not merry. It’s not *Christmas*. Desperate not to lose her contract, Rachel’s determined to find her muse at the Matzah Ball, a Jewish music celebration on the last night of Hanukkah, even if it means working with her summer camp archenemy—Jacob Greenberg. Though Rachel and Jacob haven’t seen each other since they were kids, their grudge still glows brighter than a menorah. But as they spend more time together, Rachel finds herself drawn to Hanukkah—and Jacob—in a way she never expected. Maybe this holiday of lights will be the spark she needed to set her heart ablaze.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA

**Doing KPIs Right: a KEY to Analytics (and AI!) Impact!** On the one hand, KPIs are such a Business 101 concept that it may seem a little silly to dedicate an entire session to the topic. On the other hand, KPIs get handled so poorly so often that a case could be made that this meetup could just be one of the most impactful sessions of the entire year! We’re starting off the year at a new location: [COhatch Upper Arlington](https://www.cohatch.com/locations/columbus/upper-arlington/) but with a familiar speaker, Tim Wilson! We’ll be back at Rev1 in February, when the speaker will presumably not be Tim. Tim will make the case that effectively measuring performance of projects, campaigns, and initiatives (and even meetups!) should be a foundation for any data analytics program. Topics covered will include: the “two magic questions” of performance measurement, how to help business partners distinguish between outcomes and outputs, and effective tactics for collaboratively establishing KPI targets. He will also stick his neck out by demonstrating some of these techniques in real-time by measuring whether his talk lives up to the promise of this description! All CBUSDAW events are free thanks to our 2026 Sponsors: Clarivoy, Conductrics, What Box Consulting Group, and Piwik PRO. Check out [cbusdaw.com](https://cbusdaw.com) for more information.

**History** [Blacklick Woods Metro Park](https://www.metroparks.net/parks-and-trails/blacklick-woods/), established in 1949, holds the distinction of being the first Columbus Metro Park. Its creation stemmed from a post-World War II push to preserve natural areas amid rapid suburban growth. The land, originally farmland and woodlots along Blacklick Creek, was acquired by the Columbus Metropolitan Park Board through donations and purchases. Early efforts focused on basic trail development and reforestation to combat erosion. The park's name derives from the creek, which early settlers called "Black Lick" due to its dark, mineral-rich waters. By the 1950s, it served as a model for the expanding Metro Parks system. In the 1960s, Blacklick Woods expanded significantly with additional land acquisitions, reaching over 600 acres. A golf course was added in 1964, one of the first public courses in the region, designed to generate revenue for park maintenance. Native American artifacts, including arrowheads from the Adena culture, were discovered during construction, highlighting the area's prehistoric use as hunting grounds. The park introduced interpretive programs to educate visitors on local ecology and history. Flood control measures along the creek became a priority after heavy rains caused damage. These developments solidified its role as a recreational hub. The 1970s and 1980s brought environmental awareness, leading to habitat restoration projects at Blacklick Woods. Invasive species were removed, and native wildflowers were planted in the meadows. A nature center opened in 1976, featuring exhibits on wetlands and forests. The park's slate-covered bridge, a remnant of 19th-century infrastructure, was preserved as a historic feature. Birdwatching gained popularity with the addition of observation decks. Community volunteers played a key role in trail maintenance and cleanups. During the 1990s, Blacklick Woods underwent major upgrades, including paved multi-use trails for biking and hiking. The Walter A. Tucker Nature Preserve, a 53-acre old-growth forest within the park, was dedicated in 1995 to protect rare beech-maple woodlands. Educational partnerships with local schools introduced field trips on topics like stream ecology. The golf course was renovated to improve playability while minimizing environmental impact. Annual events, such as the fall festival, drew thousands to celebrate the park's natural beauty. These enhancements balanced recreation with conservation. In the 21st century, Blacklick Woods has adapted to increasing visitation with sustainable practices. Solar panels were installed at facilities in the 2010s to reduce energy costs. The park now spans 643 acres, offering diverse habitats from wetlands to uplands. Recent initiatives include pollinator gardens and prescribed burns to maintain prairie areas. It remains a flagship for the Metro Parks, inspiring similar preservations system-wide. Ongoing archaeological surveys continue to uncover traces of early inhabitants. **Map of the Park** Here is a [map of Blacklick Woods](https://www.metroparks.net/wp-content/uploads/2025/10/BLK-map-May-2025-with-extended-greenway_1980px.jpg). **Summary** For this event, we will hike about 4.5 miles by doing a couple loops of the Buttonbush, Tucker, Maple Loop, and Beech trails. Blacklick Woods is a very nice park, but it is generally flat and not strenuous, so this will be one of the easier hikes that we do. **Where We'll Meet** Drive all the way to the back of the park to the parking lot that is nearest the Nature Center. There are restrooms here next to the Canopy Walk. We'll meet near these restrooms. Speaking of the [Canopy Walk](https://www.metroparks.net/blog/canopy-walk-is-your-gateway-to-the-sky/), it's not officially part of the event this time. However, if interested people want to freelance and check it out after the hike (before heading to the brewery), that's okay. **After the Hike** After we're done with the trails, we'll head to [Prost Beer & Wine Café](https://prostcafe.com/) for drinks and [food](https://prostcafe.com/reynoldsburg-prost-beer-and-wine-cafe-food-menu). The actual address of the brewery is [7354 E Main St, Reynoldsburg, OH 43068](https://www.google.com/maps/place/7354+E+Main+St,+Reynoldsburg,+OH+43068/data=!4m2!3m1!1s0x8838648cfb8d2dbb:0x545274bab130e9bb?sa=X&ved=1t:242&ictx=111), and we should be there by 5:00 if you just want to do that and skip the hike.
