Hello everyone, I'm happy to announce our next meetup will be hosted by [Productive](https://productive.io) (Strojarska 20, 5th floor). We'll have an interesting talk followed by a panel discussion, both centered around the challenges of "data imports". The panel brings together experts from a wide range of company sizes and language backgrounds, so we can explore the topic from hands-on implementation to broader business impact. Stick around afterwards for some food, drinks, and conversations. Hope to see you at Productive! \*\*\* **Data Imports** by Borna Artić At Productive, we import a lot of data, and doing it reliably has turned out to be trickier than it looks. In this talk I'll start with the "why": what imports solve for us, what kinds of data we bring in, and what we learned from earlier approaches. Then we'll walk through the current importer and the tradeoffs behind it: validating messy input, keeping complexity under control, and making it fast enough to run at scale. We'll also touch on edge cases like custom fields, missing relationships, and handling repeated data updates. **Panel: Data Imports Across Industries** Panelists: \- Josip Stuhli\, CTO at SofaScore \(PHP\) \- Dario Daić\, Product Architect at ButterflyMX \(Ruby\) \- Borna Artić\, Backend Engineer at Productive \(Ruby\) Moderator: Bruno Sutić After the talk, we'll keep the momentum with a panel discussion on data imports. We'll start from the hands-on problems you see in Ruby code, then zoom out to questions of architecture and long-term maintainability, and finally to the company-level impact: how data flows affect other teams, product decisions, and what the business can (and can't) do with the information it has. Expect a practical conversation with real tradeoffs rather than perfect answers. The panel brings together interesting people across seniority levels, company sizes, and language backgrounds.

Kao i svugdje, pa i u svijetu medicine, gdje su informacije opsežne i kontekst presudan, klasični “search” više nije dovoljan. **Kako izgleda AI asistent koji ne pretražuje samo ključne riječi, nego razumije kontekst onoga što gledamo ili pitamo?** Na ovom predavanju prikazat će se kako se gradi **AI agent** koji pomaže korisnicima snalaziti se u velikim bazama video sadržaja i dokumenata pri **rješavanju stvarnih problema**. Kroz primjer **Video asistenta za zdravstvene djelatnike** vidjet ćemo kako moderni AI sustavi koriste Large Language modele (LLM), vektorsko pretraživanje i kontekstualnu analizu kako bi: \- razumjeli o kojem se sadržaju trenutno govori \- povezali informacije iz velikih baza podataka \- davali smislenije i preciznije odgovore **Predavač:** **[Domagoj Gojanović Božić](https://www.linkedin.com/in/domagoj-gojanovi%C4%87-bo%C5%BEi%C4%87-30753819a/)** Senior Software engineer @ [Vumedi](https://www.vumedi.com/) Domagoj se bavi razvojem AI rješenja koja stavljaju korisnika u fokus — od pametnih chatbotova do kompleksnih sustava za pretraživanje velikih baza znanja. Kroz svoj rad istražuje kako AI može razumjeti kontekst i pomoći ljudima da brže i lakše dođu do relevantnih informacija, a na ovom predavanju podijelit će iskustva iz stvarnih produkcijskih projekata. **Predavanje je otvoreno za developere i freelancere, studente i tech entuzijaste i sve znatiželjnike koje zanima AI, bez obzira na razinu znanja.** **Ekstra pojmovi:** AI, LLM, AI Agents, Agentic Chatbot, RAG, OpenSearch, ElasticSearch **Okvirni raspored:** **17:15** \- Vrata **17:35** \- Predavanje **19:00** \- Druženje ***🇬🇧:*** *In this talk, we will explore the engineering behind building an **Agentic Chatbot** designed to **help clinicians navigate vast libraries** of surgical videos and medical transcripts. If Croatian is not your native language and you're interested to attend the event, the presentation can be held in English so please **RSVP** and reach out to the organizer.*

Na samom početku 2026. godine za koju želimo da vam bude uspješna na svakom planu pozivamo vas da nam se pridružite na **8\. ZGBit\-u** na kojem će u kratkim crtama biti predstavljni projekti korištenja otvorenih podataka koje Grad Zagreb sufinancira drugu godinu zaredom. Kao što znate, Grad Zagreb prošle je godine pokrenuo BAJS - sustav javnih bicikala grada Zagreba, a na 8. ZGBitu-u predstavit ćemo i aplikaciju koja prati dostupnost javnih bicikala, analizira njihovo kretanje i jhoš mnogo toga. Dođite vidjeti kako otvoreni podaci postaju alat za pametniji, mobilniji i transparentniji grad! Vidimo se na starom mjestu u ZG Forumu u **Gajevoj 27 u četvrtak 29.siječnja 2026. godine u 18.00 sati!**

At the last meetup, we examined WooCommerce under pressure. Security failures, AI agents behaving badly, and real examples of how stores get compromised. This time, we’re flipping the angle! The Winter 2026 Zagreb WooCommerce Meetup focuses on how the platform is being built and steered today. We’re hosting speakers from Automattic and the WooCommerce team to walk through recent platform updates, what’s currently being prioritized, and what’s coming next. You’ll hear what has shipped, what’s changing in key areas like checkout and blocks, and how upcoming work is likely to affect developers and merchants building on Woo. You’ll also get roadmap context straight from the people shaping it. Seeing these folks in person in Croatia doesn’t happen often! If you build, maintain, or sell on WooCommerce, this meetup should make your next set of technical decisions easier. **+++++++++++++++++++++** **Lecture 01** **\- What’s new in Woo: latest updates & what’s coming next** WooCommerce has been moving fast. Checkout extensibility, shipping and fulfillment changes, block-first experiences, the Interactivity API, and a growing layer of AI features are no longer “experimental” but becoming the default. In this talk, Brian and Shani will walk through the most important recent changes in WooCommerce and what’s coming next. Expect concrete examples, platform context, and guidance on how these changes affect real-world Woo builds. **Brian Coords** is a developer advocate at WooCommerce and a long-time WordPress developer, writer, and instructor. He hosts a WordPress podcast at Webmasters_fm and writes for WP Tavern, MasterWP, The WP Minute, and his own technology blog. **Shani Banerjee** is a developer advocate at WooCommerce, where she hosts monthly developer office hours and writes about platform updates and extensibility on the WooCommerce developer blog. Her work is shaped by a strong community-first background spanning support, software engineering, and education. **+++++++++++++++++++++** **Lecture 02** **\- The state of WooCommerce: where we are & where we’re going** In this session, Brent will zoom out and talk about how WooCommerce is positioning itself today: what’s driving the roadmap, how Woo thinks about high-growth merchants, and how the platform is evolving to stay competitive in an increasingly crowded eCommerce landscape. This is the “why” behind the updates which will help you understand the bigger picture: the product, market, and ecosystem context that rarely gets discussed outside closed rooms. **Brent MacKinnon** is director of product marketing and developer advocacy at WooCommerce (Automattic). He leads go-to-market strategy, developer relations, and analyst engagement, and focuses on making complex platform decisions understandable to builders and merchants alike. He’s based in Halifax, Canada. **+++++++++++++++++++++** **AGENDA** 18:00 - Meet & greet 18:05 - Talk: What’s new in Woo: latest updates & what’s coming next 18:40 - Q&A 19:00 - Talk: The state of WooCommerce: where we are & where we’re going 19:35 - Q&A After - Pizza & Beer 🍕🍺

Iako smo konstantno u limbu marketinga, klijenata i kampanja ili bombardirani kao potrošači, i dalje se provlači isto pitanje: Što je zapravo osnova marketinga? Koji su to fundamenti marketinga koji se (pre)često zaboravljaju, dok svi ganjaju „brze“ pobjede, nagrade i metrike koje dobro izgledaju na slajdu? Jednostavne stvari za shvatiti, ali istodobno složene za ostvariti. Kako graditi dugoročno brend kroz prepoznatljivost i memorijske strukture, uz pametne kratkoročne aktivacije? Upravo o temeljima marketinga i izazovima koji stoje na putu dugoročno održivom brendu razgovarat ćemo na panelu, kao i o tome koje su najčešće slijepe točke marketingaša.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/cbus-hug-2026/
