Since there is no regular meetup, let's meet, talk and if we get fancy, perhaps write a line of code or two.

Ok everybody, it's 2026, and after taking a break for the holidays, games are starting up again as usual. We'll meet, have a beer, and play a round of cards against humanity. Laughs will be had, groans will be groaned, beer will go down the hatch. This event is public, and prior experience with the game is not required. You are not required to drink alcohol, but please note that we are crashing a bar (cash only), so a beverage purchase or two is appropriate and necessary for us to maintain their goodwill. See you there!

BHNT 110: the third BHNT in 2026. The title is inspired by [Human brain cells on a chip learned to play Doom](https://www.newscientist.com/article/2517389-human-brain-cells-on-a-chip-learned-to-play-doom-in-a-week/) \- but also the doom and scrolling through it all around us currently\. Your hacks do not have to be connected to the title (bonus points if they do though) Please RSVP and bring your hacks! There are 8 dynamically allocated Slots that consist of 5min presentation + 5min conversation with the audience. To refresh your memories or get familiar with the concept - see some old hacks here: [https://bhnt.c-base.org](https://bhnt.c-base.org/) Hope to see you - looking forward!

## Beads: Go Open Source Projects in the Age of AI Hello, 世界! For meetup #58 on Tuesday [Mar 31, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537698/) we are happy to have [Akim Zmerli](https://www.linkedin.com/in/akimzmerli/) give us an intro to [beads](https://github.com/steveyegge/beads), specifically: > How agents perform long-running tasks and pass context seamlessly to each other. [Beads](https://github.com/steveyegge/beads) is a rising Go project that brings structured planning to any workflow, whether agentic or hands-on. [Akim Zmerli](https://www.linkedin.com/in/akimzmerli/) will present his favorite techniques, TUI projects and what Rob Pike thinks about the current state of affairs. The beads project is less than six months old (2025-10-11), but already well beyond 250 KLOC, with more than 200 KLOC written in Go. We are always interested in developer tools. At [#44](https://golangleipzig.space/posts/meetup-44-wrapup/), less than two years ago, not a single AI coding tool did make it to [our list](https://golangleipzig.space/posts/meetup-44-wrapup/). Looking forward to this foray into the agentic coding space. ### Schedule * 18:45 Doors open * 19:00 Welcome * 19:10 Beads * 19:45 Open discussion We’ll meet: * in person at [Basislager Leipzig](https://basislager.co), at [Peterssteinweg 14, 04107 Leipzig](https://maps.app.goo.gl/1fMkeDSPZ7Aauszh8) ([OSM](https://www.openstreetmap.org/node/3504864558)) * and online via [Jitsi](https://meet.jit.si/LeipzigGophers58) Join us to discuss SOTA dev tools and more.

**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2). Then, you go upstairs and our private room is in the far end corner of the building. We are a relaxed, non-formal meetup of like-minded software engineers who want to always keep learning and want to meet in physical reality over a drink or two.

Hello everyone, Due to popular request (and some other reasons, like venue availability and available organiser capacity), we’re happy to announce that the Rust Berlin talk meetups are back. This is the classic meetup format: let’s meet in the evening see 2 speakers and then spend some idle time chatting about what we heard. The first speaker for the first edition will be our co-organiser Florian Gilcher, speaking about “Unsafe demystified”, a gentle introduction into handing unsafe code properly. Soares Chen will talk about the current revision of Context Generic, their framework for context generic programming: https://contextgeneric.dev We are also available for new talks, in particular of people who never gave a public talk. We’re happy to be your first talk location. The new meetup is currently organised by Florian and Liran, who is a new co-organiser at Rust Berlin. JetBrains was so kind to offer us their office location as a default meeting point. Thank you! We’re looking forward to getting the ball rolling again! See you all on April 1st! **Line-Up** Unsafe demystified by Florian Gilcher This is a beginner- to mid-level talk that explains the basics of unsafe and how to program it. Instead of going fully into it all details of unsafe, this talk teaches you easy to digest mental frameworks to use when approaching your next unsafe code block. Supercharge Rust functions with CGP implicit arguments by Soares Chen I will give a short overview of the new implicit arguments feature for Context-Generic Programming (CGP), which enables structural typing in Rust. Some short example demos will be presented, followed by some explanation of how the feature works. **Speaker Bios** Florian Gilcher Florian Gilcher used to be part of the Rust team at several positions and served as a member of the Rust Foundation board. He is also a co-founder of the Rust Berlin meetup. Today, he’s training Rust at Ferrous Systems, a company he co-founded. Soares Chen Soares is a Rust programmer with a strong interest in functional programming, type theory, and programming language design. He is the creator of Context-Generic Programming and currently works as a Rust engineer at Tensordyne.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!
