**Hosted by Pure Storage** Please note at the Pure Storage office, all meetup attendees will be required to sign a generic NDA used for all office visitors to be able to attend the meetup. Doors are open from 17:30, talks will start 18:00, and we have 2 talks and panel discussion. **1\. Daniel Turecek \(Pure Storage\) \- What is new in Go 1\.26** In this lightning talk, we’ll tour what’s coming in **Go 1.26** (based on the current draft release notes) and why it matters for real-world services. We’ll cover runtime and performance wins like the default **Green Tea GC**, faster **cgo** calls, improved stack allocation, and new profiling options aimed at spotting goroutine leaks. We’ll also look at security and crypto upgrades including 64-bit heap address randomization, the new **`crypto/hpke`** package, and **post-quantum hybrid key exchange on by default in TLS**. Finally, we’ll touch on pragmatic developer-experience changes—from `new(expr)` and richer generics constraints to tooling updates like `go fix`, `pprof` flame graphs by default, and compatibility-oriented module defaults. **2\. Vilibald Wanca \- Nail the Basics \- S01E02** Good Go code starts with a simple, predictable layout. In this talk, we’ll cover the standard approach to structuring Go projects: keep things flat early on, map one package to one directory, and keep tests right next to the code they validate (like `user.go` and `user_test.go`). We’ll also look at common structural mistakes—such as over-engineering too soon or importing Java/Python-style layering that fights Go’s package model—and how to avoid them. Finally, you’ll leave with a handful of quick wins you can apply immediately: formatting and import automation with `gofmt`/`goimports`, stronger feedback loops with `golangci-lint`, and editor setups (VSCode Go extension or GoLand) that make the “Go way” feel effortless. **3\. Panel discussion with our speakers on AI tools and Go development** Join us for a panel discussion with our speakers on how AI tools are changing Go development in practice. We’ll compare real workflows for using assistants to design, code, test, refactor, and review Go services—what actually saves time, what introduces risk, and where humans still need to stay firmly in the loop. Expect practical tips on prompt patterns, maintaining code quality, avoiding “AI-shaped” over-engineering, and integrating AI into existing tooling like linters, editors, and CI. Bring your questions—we’ll keep it candid, concrete, and Go-focused.

We’ve got another portion of AI talks for you, so come to our second Prague Gen AI Meetup of the year. ## NEW VENUE (very important) **Pracovna & Laskafe** Vlkova 628/36, 130 00 Praha 3-Žižkov ## Venue Schedule * **18:30** Doors open * **18:45** Talks start * **20:45** Talks end * **21:00** Snacks and beer ## What’s On The Agenda * **Talks:** Again, no hype, just the stuff you want to know. * **Snacks and Beer:** Grab a bite and a brew while talking shop. * **Networking:** Meet other people in the field. No fluff, just good tech talk. ## Talks ### Šimon Podhajský (Head of AI @ Waypoint) **The Eval Flywheel: From "Works on My Laptop" to Systematic Quality** Most teams shipping GenAI products have no evaluation system. They have vibes, a few saved prompts, and hope. This talk doesn’t start with “build an eval suite”, it starts with **observability**: if you can’t see what’s happening in production, nothing else matters. From there, we build the **eval flywheel**, a practical pattern where production observability feeds error analysis, error analysis generates eval cases, and eval cases prevent recurrence. Your evaluation suite isn’t something you design upfront, it’s something that grows out of understanding your production failures. ### Ondřej Romancov (Engineering Lead @ Duvo.ai) **Building agents with agents** Duvo is building a platform for AI agents, and we’re running our engineering on agents too. Sharing practical tips and workflows we’ve found useful along the way. Let’s get down to the real talk.

In a world full of opinions, noise, and quick reactions, we often miss spaces for real dialogue — for slowing down, listening, and connecting with one another. This evening is an invitation to do exactly that. Join us for an open and friendly evening (in English & free of charge) dedicated to Automated Commonwealth (UBI - Universal Basic Income), can we use AI for people's welfare? Is it a basic income what we really need? We will brainstorm together in an Open Space–style format, where participants choose topics themselves, and what we want to discuss from this broad topic - questions to help you get inspired: Is it possible to achieve automated UBI? Is UBI what we need, or is it better social infrastructure? How do we start building such system? Afterwards, participants will form small groups to explore the questions and insights around the topics 18:00 – Doors open 18:15 – Introduction & topic selection 18:40 - We start discussions 19:40 - Closing session (sharing activities) 20:00 - Networking & Connect What to expect: A welcoming space for newcomers and regulars alike Be slightly pushed to socialise Open, participant-led small-group discussions on diverse perspectives No expertise required — everyone’s opinion matters! Safe, respectful, and judgment-free conversations More about sharing and reflecting than debating or convincing No pressure to speak — listening is just as valuable Not a lecture, not a debate club, and definitely not intimidating! Feel free to bring some snacks to share! Friendly dogs are welcome! If you are a regular that appreciate us and can help, or a newcomer who enjoyed the evening, and wants to help, we have recently set a patreon page where you can support us! https://www.patreon.com/cw/EarthSocietyDialogues

Filozofování o životě a o všem ostatním pro všechny, bez vstupného a bez přihlášky: Co si přejete, s čím si lámete hlavu, co Vás nenechá spát, o čem dumáte, o čem sníte, co Vám vrtá hlavou, čeho se bojíte, na co vzpomínáte, o čem přemýšlíte? Nenechte tyto věci jen pro sebe, zkuste rozhovor s jinými lidmi. U nás nejde jen o to, si popovídat, o to taky, ale to máte i jinde. U našeho stolu se pokusíme, spolu *filozofovat*. Nejdříve se dohodneme, jaké téma budeme diskutovat, a pak se do toho pustíme, budeme přemýšlet, rozmýšlet, promýšlet a zamýšlet se, až se nám z toho bude točit hlava, přitom nám budou podporou filozofové všech věků, abychom jí neztratili, tu hlavu. Ani byste nevěřili, jak filozofie může být osvěžující…
