OWASP

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

**Format**: Hybrid (in-person and online) event **In-person location**: **Security Compass** 325 Front Street West, Unit 103 Toronto, ON M5V 2Y1 **Note:** In-person attendance is limited to **70 people**, in a **first-come, first-serve basis**. Doors will open at **6:00 PM**, with the event will start at **6:30 PM** (ET). For those who cannot attend in person, please join us virtually via the livestream! **Presentation Title:** **Privacy Components That Should Actually Matter to Development Teams** Many teams expect that privacy is taken care of by the company’s security program or addressed by the legal and compliance teams. Fact is, privacy is often lagging behind security when it comes to software development, and there are still obligations that need to make their way into the lifecycle. And, in many cases, devs never even see the obligations that exist on paper to clients! In each business function of Governance, Design, Implementation, Verification, and Operations, there are privacy considerations that need to be made. The earlier you can get these considerations locked in, the more time it saves you later when there’s an incident, a user exercising their rights, or simply scaling up! \-\-\- **This is a hybrid event!** You're welcome to join us online or in person. Thanks again to our wonderful sponsors at **Security Compass** for hosting us!

**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.

Let's have lunch at Uptown Westerville's newest restaurant. Ampersand is owned by the same couple who owns Asterisk. They are known for ramen, rice bowls, teriyaki and small plates.

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!

As we step into a new year, many of us are carrying lessons, practices, and questions shaped by the year behind us. The Next Chapter: Looking Back, Leaning Forward is a warm, facilitated vision circle designed to help us pause together, reflect on what truly worked, and imagine what we want to carry forward into what comes next. This is not a talk or presentation. It’s a small, participatory gathering focused on shared reflection, sense-making, and connection. **Together, we’ll explore:** * What supported you over the past year — in your work, leadership, or life * What you’re ready to leave behind * What you want next January’s version of yourself to be saying To support reflection in different ways, we’ll also have optional art materials available for anyone who would like to create a simple artifact for their year — a visual or tactile reminder of what they’re carrying forward. We’ll provide basic art supplies such as colored pencils, markers, paint pens, and small canvases. If you enjoy working with collage or other media, you’re warmly invited to bring magazines, stickers, or your favorite creative materials to use or share. Participation in the creative portion is completely optional. You don’t need a plan, goals, or polished answers. Curiosity, honesty, and listening are more than enough. The intention is for everyone to leave feeling grounded, refreshed, and inspired — with a clearer sense of what matters to them and how we can support one another as a community. Space is intentionally limited to keep the experience intimate. ⸻ **What to Expect** * A small, welcoming circle (not a large meetup) * Structured conversation so everyone has space to speak * Reflection, listening, and lived experience — not advice-giving * Optional creative reflection using simple art materials * A calm, supportive environment ⸻ **Who This Is For** Women and underrepresented folks working in or around agile, product, technology, leadership, or organizational change — especially those looking for thoughtful conversation and community beyond frameworks and buzzwords. ⸻ **Good to Know** * No preparation required * Participation is invitational; listening is always welcome * Creative activities are optional — you can simply listen and reflect * You’re welcome to bring your own collage or craft materials if you’d like * Location details will be shared with registered attendees

**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.

**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

2026 may be the last year many developers write code by hand. We need coding agents to solve complex problems in production codebases, but vibe coding alone won’t get us there. Vibe coding is all gas, no brakes. It burns up the context window until the agent slips on its own slop. You can go fast at first, but the more you stuff into the context window, the more tangled its outputs get. While the industry is rapidly increasing code generation speed, we still have to understand, review, merge, and maintain what gets shipped. This talk featuring Michael Geiger will outline how coding agents (Claude Code + Gas Town) work and a framework for orchestrating them to solve complicated problems in complex codebases. It’s about steering the model: doing the research to align intent, planning the approach up front, implementing in parallel steps, and breaking early. Human judgment still matters, but it should be spent on high-leverage decisions: what to build, what to forbid, and “what is quality?”, not cleaning up slop. Attendees will leave with a checklist to identify workflow and environment gaps that hold agents back, so you and your team can ship higher-quality software starting tomorrow.
