Agnostic

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.

Jimmy V's Grill & Pub in Grandview Heights. You are responsible for your own meal/drinks. We usually don't have any agenda other than eat, drink and talk. :) If the weather is nice we will be on the back patio, otherwise we are in the cigar room. This group has been meeting every Tuesday evening for over a decade. Many attendees do not RSVP on meetup. Please don't let the small number here discourage you. Anyone/everyone is welcome to come. We'd love to have you join us. COTA bus #5 comes to W. 5th and Wyandotte Rd. And it's a minute walk to the restaurant.

Come assist Van Buren Shelter (https://ymcacolumbus.org/locations/vanburen) staff in serving dinners and cleaning up on the 3rd Tuesday of each month. Dinner for the women is 5-6 pm and for the families is 6:15-7:15 pm. There is ample free parking available in the shelter's lot. The recommended area to park is in green in the image above. There will be a new entrance for the time being. We are asking all volunteers to enter through the Donation Dock door, the orange mark on the image above. This door is located between the Single Adults and Family Shelter. You will see 2 large garage doors with a large green trash compactor in the center. Please head to the closest garage door to the building wall, with a ramp leading up. There, you will see a door with a sign stating instructions on how to enter the building. Please ring the doorbell, and a staff member will come and escort you into the building. If a staff member takes longer than 5 minutes, please call the front desk at 614-689-2020. This is a new process for us, and we do not want to keep you waiting! We appreciate your patience as we navigate this temporary change. The shelter needs a volunteer count the day before the event so sign-up ends Monday at 4:50 PM. Afterwards some of us go to the Omnipresent Atheists Weekly Meetup in progress to have a bit to eat or drink (http://www.meetup.com/omnipresentatheists/). Volunteers must be 14 or older. Since we will be working around families, the YMCA does not permit volunteering by individuals with convictions for violent or sexual crimes. The YMCA reserves the right to run background checks on volunteers. For questions, comment on this page or contact: Andrew, awhit12@yahoo.com, (614)937-5802 (cell). Please let Andrew know if you volunteer anytime other than our COUNT events so that he can count your hours toward our service record.

Open Shelter has teamed up again with Red White and Boom! Friday, July 3rd & we are looking for volunteers to run the event’s alcohol booths. Proceeds from sales go to the Open Shelter’s organization. There are two available shifts: 12-6p & 5-11p. There will be an ipad-like device to process transactions in addition to cash. Everything will be in bottles or cans, so transactions should be very easy. Must be 21+. There are multiple beverage stations along the Civic Center Bridge. The stations are covered and also have beverage trucks next to them, so volunteers can cool off in the trucks. As far as parking, it is suggested those who are coming from the east use the Columbus Commons Garage, and those from the west use the Belle Street Garage. Harry from the Open Shelter will be your contact.
