Software Architecture

Come and join us on Jun 18, 2026 for a dive into a topic that impacts everyone using Python. (**Important**: The event requires a mandatory registration) Everyone knows that there is no real multithreading in Python - or is there? The tradeoffs between processes and threads is well known. But what if we could have the best of both worlds? This is where subinterpreters come in. We will go over what subinterpreters are, how they work, and most importantly, how we can use them to make our code faster. We will also go deeper into Python’s internals and explore what a GIL-less Python looks like. The “freethreaded” builds of Python are easily accessible - but are there drawbacks? After that, we can have a quick chat and enjoy some drinks and pizza (provided by SiteGround) If this sounds interesting to you, make sure to sign up below: **Speaker bio:** Lyuboslav Karev has 6 years of experience with anything Python related - web development, automation, AI and Machine Learning.

In early May, two of our Atlassian experts packed their bags and flew to California for Atlassian Team '26 - one of the biggest gatherings in the Atlassian ecosystem. Georgi and George spent several intense days in Anaheim, sitting through keynotes, joining partner sessions, hosting conversations, and talking to people from organizations across the world who are wrestling with the same questions we are. They're back now. And we thought the best way to share what they learned is an evening with beer and pizza. So what did they actually bring back? The biggest shift was a fundamental change in how Atlassian is positioning itself - not just as a suite of tools your team uses, but as the layer that makes your organizational knowledge usable by any AI system you're already working with. The data your teams have been building for years in Jira, Confluence, and JSM - the workflows, the ownership, the history - is now something external tools can actually access and act on.  On the AI side, Rovo moved well beyond being a smart assistant. The new direction is about AI that takes on real work: breaking down complex requests, executing multi-step tasks, and doing it in a way that stays visible and auditable. Non-technical people can now build automations by describing what they need in plain language. Engineers can ask questions across entire multi-repo codebases. And for the first time, organizations will be able to see exactly where their AI investment is going - and whether it's actually connected to anything strategic. Join us for an informal evening where we unpack all of it and what it means for the way we work.  Agenda --- Speakers Georgi Gachev - Nemetschek Bulgaria (Team Lead) Gogo is a software developer for almost 15 years and he had experience with all kinds of technologies including Java, .NET, Android, Javascript, Python and more.

I specialize in building high-performing teams, and bridging the gap between business goals and tech execution. My mission is simple: I help systems and people work better — starting with myself, and never stopping at “good enough.” I thrive where complexity meets urgency — whether it's redesigning inefficient workflows, elevating engineering culture, or aligning delivery with long-term value. I bring a strong foundation in internal auditing practices, ensuring that systems are not only efficient but also aligned with key compliance and quality standards like ISO 27001 and ISO 9001 — without losing sight of the human side of work. I’ve also developed a strong interest in artificial intelligence — not just as a tool, but as a transformational force. I’m exploring how AI can enhance quality, automate the right parts of work, and help us build more adaptive, intelligent systems that serve both business and society responsibly. I believe the future of tech depends not just on innovation, but on responsibility, empathy, and structure that serves both people and planet.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: This month Chris Pazsint will be talking about Agentic Coding.

We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com

On Thursday, June 18, 2026, we will meet in the 700N Conference Room at 700 N Hurstbourne Pkwy for a special Louisville .NET Meetup as we host **Microsoft Build //localhost:louisville**. Doors open at 6:00 p.m., and the presentation will begin promptly at 6:30 p.m. TEKsystems will provide food, so please RSVP to help us plan appropriately. The session will also be streamed at **[https://twitch.tv/TaleLearnCode](https://twitch.tv/TaleLearnCode)**. This month, we’ll dive into the most important announcements from **Microsoft Build 2026**. Chad Green will present a curated, developer‑focused walkthrough of the new capabilities across .NET, Azure, AI, developer tooling, and platform updates. We’ll explore what these announcements mean for architects and developers, how they fit into real‑world solutions, and which changes you can start applying immediately in your projects. And then, Rob Richardson will present: ### **GitOps: Easy Deploy and Even Easier Rollback** GitOps isn't just for containers. The methodology of deploying from a build is now baked into our culture. Take it a touch farther with infrastructure as code and a few extra techniques, and you can reliably deploy to any platform: cloud, on-prem, container, PaaS, and more. Join us as we learn the methodology of GitOps, the critical pieces you need in place, and the elegance of rollbacks with GitOps. You'll leave with a working repo of deployment techniques that doesn't consume any paid tools or container-specific techniques. **Important:** To participate fully, please RSVP in **both** places: * **Louisville .NET Meetup** (this page) * **Microsoft Build //localhost:louisville registration**: [https://developer.microsoft.com/en-us/reactor/events/27112/](https://developer.microsoft.com/en-us/reactor/events/27112/) After the session, we’ll head to Brick House Tavern to continue the conversation over food and drinks.

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!

We are going to build together with all the CLIs! E will be doing it at Columbus Code and Coffee Agenda --- Hosted By James Power, Organizer Pete Gordon, Organizer Just a Software Guy in the age of the Internet.
