Python

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 his current role at SiteGround, he works on Coderick AI - an AI-powered coding platform, which allows its users to create and host sites, business tools, and apps. In his free time, he is part of the Python course in Sofia University. **Agenda:** 19:00 - 19:10: Opening & introduction 19:10 - 19:45: Subinterpreters & GIL-less Python 19:45 - 20:30: Networking with drinks and pizza (provided by SiteGround) **Place:** SiteGround HQ , 6 Olimpiyska st., Sofia **Parking:** available\*\*.\*\* **Directions:** [https://www.google.com/maps/place/g.k.+Sofia+parkMladost,+ul.+%22Olimpijska%22+6,+1766+Sofia/@42.6228344,23.3692001,3a,90y,270h,84.41t/data=!3m7!1e1!3m5!1sxcFgY8KOgVqqw7dZJ-Y70w!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fcb_client%3Dmaps_sv.tactile%26w%3D900%26h%3D600%26pitch%3D5.590685654068935%26panoid%3DxcFgY8KOgVqqw7dZJ-Y70w%26yaw%3D270!7i16384!8i8192!4m6!3m5!1s0x40aa813466d6ce39:0xb464d77033cdd740!8m2!3d42.6229584!4d23.3679717!16s%2Fg%2F11sjsgh0c6?entry=ttu&g_ep=EgoyMDI2MDMyNC4wIKXMDSoASAFQAw%3D%3D](https://www.google.com/maps/place/g.k.+Sofia+parkMladost,+ul.+%22Olimpijska%22+6,+1766+Sofia/@42.6228344,23.3692001,3a,90y,270h,84.41t/data=!3m7!1e1!3m5!1sxcFgY8KOgVqqw7dZJ-Y70w!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fcb_client%3Dmaps_sv.tactile%26w%3D900%26h%3D600%26pitch%3D5.590685654068935%26panoid%3DxcFgY8KOgVqqw7dZJ-Y70w%26yaw%3D270!7i16384!8i8192!4m6!3m5!1s0x40aa813466d6ce39:0xb464d77033cdd740!8m2!3d42.6229584!4d23.3679717!16s%2Fg%2F11sjsgh0c6?entry=ttu&g_ep=EgoyMDI2MDMyNC4wIKXMDSoASAFQAw%3D%3D)

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. His passions include football, e-sports and travelling. George Stoyanov - Nemetschek Bulgaria George is an experienced professional in the field of software technologies for more than 20 years. Currently he is in charge of leading projects of Atlassian tools implementation, support, integrations and add-ons development in Nemetschek Bulgaria. For the last 5 years his deep technical knowledge and management skills have helped a number of organisations to get the most out of their Atlass… Moderators Velizar Borisov - MBition Sofia (Atlassian Community Champion) Boriana Todorova - Altassian Community Champion Hosted By Velizar Borisov, Atlassian Administrator Boriana Todorova, Community Leader I'm a senior technology leader with 20+ years of experience in quality assurance, process improvement, project delivery, and organizational transformation. 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.

**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: In this session, we will explore the concept of hyperdimensional computing (HDC), a brain-inspired method of computing. We'll begin by talking about neurons and the brain. Through simple Python examples we’ll dive into HDC and answer: What it is? How does it work? And, how does it learn? We will review how other researchers have applied HDC and demonstrate how it can be used for solving cybersecurity tasks. Where deep learning fails, HDC excels. No supercomputer? No problem. HDC offers interpretability, low energy requirements, robustness to errors, online learning, on-device learning, and more. By pushing the difficult calculations into the embedding process, learning becomes a cinch. By the end of this talk, attendees will have everything they need to teach their own hyperdimensional computing models. 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

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

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
