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.

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.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle. **Optional topic for this meetup: Where is everybody?** In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox. One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread. Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for. **Questions to wrestle with:** * Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving? * Where do you bet the filter sits, behind us or ahead of us, and why? * If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming? * Does any of this change how you live, or how humanity should be spending its time and money right now? As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.
