Product Launch

🇭🇷 Programiranje u paru je kada dvije osobe rade na istom zadatku, za istim računalom, u isto vrijeme. Na prvi pogled zvuči dvostruko skuplje — kako to uopće može biti jeftinije? U ovom predavanju istražit ćemo zašto je ta intuicija pogrešna. Pogledat ćemo kako solo programiranje tiho gomila skrivene troškove, te kako programiranje u paru, kada se pravilno prakticira, sprječava mnoge od njih prije nego što nastanu. Pridružite nam se i saznajte zašto bi rad u paru mogao biti najpametnija investicija koju možete napraviti. 🇬🇧 Pair programming is two people working on the same task, at the same computer, at the same time. At first glance, that sounds twice as expensive — how could that possibly be cheaper? In this talk, we’ll explore why that intuition is wrong. We’ll look at how solo programming quietly accumulates hidden costs, and how pair programming, when practiced well, prevents many of them before they form. Join us and discover why working in pairs might be the smartest investment you can make. 📣 Speaker: [Marko Bjelac](https://www.linkedin.com/in/markobjelac) ⏰ Schedule: \- Introduction \- Pair programming is cheaper \- Q&A or ⚡LIVE PAIRING⚡ \(if test subject is acquired\) ©️ Image by [freepik](https://www.freepik.com/free-vector/people-cooking-illustration_7882565.htm)

Hi everyone! Join us for the RubyZG February. We'll hear about building a query builder with AI and what is like to work at a company where Ruby On Rails itself was created. This event is hosted by [DECODE](https://decode.agency/about-us/) who will be providing snacks and refreshments after the formal part of the meetup. Btw. they are hiring, so be sure to check [their open positions](https://decode.agency/open-positions/). For those coming by car, there is no dedicated parking but there should be plenty of parking at that time in the street in front of the building. See you at DECODE! \*\*\* How to use AI agents to build query builder by [Lovro Žmak](https://www.linkedin.com/in/lovro-zmak-22706253/) Does code generation with AI agents always help or is it better to manually write it sometimes ? How does Arel fit into the story and how did it influence the code design decisions ? This talk will bring you the story of building a query builder with AI agents, from initial wrong directions to the final solution. Through practical examples and live demos, you will receive guidelines on how to use AI agents to generate usable and sustainable code. **Working at 37signals: The birthplace of Ruby On Rails** by [Stanko Krtalić Rusendić](https://www.linkedin.com/in/stanko-krtalic/) Last July Stanko started working at [37signals](https://37signals.com/), the company behind Basecamp, Hey & Fizzy and the place from which the very first version or Ruby On Rails was extracted back in 2004. It's still the company with the largest influence on the direction of Rails development with major contributions like ActiveStorage, SolidQueue, Turbo & Stimulus. We'll hear how the company works and what it's like to work there.

Speaker: **Tomislav Maričević** Title: **Nix ❤️ Python: Maybe you don't need devcontainers after all** Life is too short to wait for Docker image rebuilds during everyday development. This talk shows how Nix and devenv provide deterministic, host-native development environments that model compilers, runtimes, system libraries, and tooling as a reproducible dependency graph — eliminating much of the toolchain complexity developers often push into Docker and Docker Compose. We will compare the failure modes each approach addresses, demonstrate where devenv can replace Compose in local workflows, and clarify where containers remain the correct abstraction. \-\-\-\-\-\-\-\- Join us on **Tuesday** at MaMa for a fun technical deep dive. Drinks and, most likely, very opinionated discussion afterwards at [Old Pharmacy Pub](https://maps.app.goo.gl/AeaRdnBrMqPiRhvPA) 🍻🍷🥤☕️

Franjo Kmet – Profesionalni planinski i gorski vodič Osnivač i voditelj brenda **Mountain Fit** – programa usmjerenog na planinarenje, alpinizam i outdoor aktivnosti. Voditelj planinarskih škola, visokogorskih tečajeva, ledenjačkih i sportsko-penjačkih programa. Strastveni prenositelj znanja i iskustava iz planinarenja i alpinizma. Organizator i vodič uspona, trekinga, ekspedicija i planinarskih izleta diljem svijeta – od Alpa do Himalaje i Patagonije. Planine su prirodni "terapeut" koji djeluje na više razina – od fiziologije (endorphini, serotonin) do egzistencijalne promjene. Najmoćniji efekt često dolazi upravo kroz smanjenje ega – kad ego prestane biti glavni lik priče, um postaje tiši, otvoreniji i sretniji. Teme LevelUp Meetup-a: **Smanjenje stresa i anksioznosti** Planine pružaju tišinu, ritmično hodanje i fokus na svaki korak – to brzo prekida krug briga i pretjeranog razmišljanja. * **Povećanje osjećaja prisutnosti i mindfulnessa** Hodanje po stazi, disanje na većoj visini, promatranje oblaka ili slušanja vjetra prirodno nas uvodi u „ovdje i sada“, smanjujući mentalni šum i preopterećenost mislima. * **Doživljaj strahopoštovanja i šire perspektive** Pogled s vrha, ogromnost planina i beskrajno nebo izazivaju duboki osjećaj strahopoštovanja. * **Povećanje samopouzdanja i osjećaja postignuća** Svaki uspješan uspon, savladavanje tehničkog dijela ili dolazak na vrh gradi unutarnju snagu i samopoštovanje. * **Povećana povezanost s prirodom i osjećaj smisla života** Boravak u planinama jača osjećaj da smo dio prirode. Napredak je nemoguć bez promjene, i oni koji ne mogu promijeniti svoj um ne mogu promijeniti ništa! 📍 Pivana, Ilica 222, Zagreb 🗓 11.02.2026. u 18:00 h Organizator: Međunarodni institut za emocionalnu zrelost – zajednica poduzetnika, stručnjaka i znanstvenika posvećenih razvoju pojedinaca i društva.🌐 http://emotionalmaturity.eu

**Autogenic training** is a method that, by directing attention to specific parts of the body and entering a state of deep relaxation, reconnects the brain with the body. By establishing communication between the brain and physical organs and body parts, we can positively influence our overall health.

The training will take place on **February 13 and February 20, 2026**, both dates being **Fridays at 6:30 PM**. The session on **February 20** will be held as a **dual-language session**, in **Croatian and English**, so participants who do not understand Croatian are also welcome. **No prior registration is required.** The donation is **€15**.

**\*\*\*\* More details and sign up at: https://aifalliance.org/summit-2026/ \*\*\*\*** **What is AI Freedom Alliance?** AI Freedom Alliance promotes the responsible growth of AI guided by practical, commonsense ethics. Our nonprofit is built by professionals from a wide range of industries and is made up entirely of small- and mediumbusiness representatives—never large tech companies. We provide a counterbalance to big corporate influence, focusing instead on how AI can benefit businesses and the world at large. **What’s Happening?** ***The inaugural AI Freedom Alliance Summit.*** This full-day event will explore how we can ensure AI is adopted responsibly through shared ethical standards that empower humanity. The summit will feature interactive and educational sessions led by thought leaders, technologists, policymakers, and advocates who are passionate about making AI fair, transparent, and beneficial for everyone. **Why Attend?** Learn about the legal and technical challenges with implementing AI solutions within your organization. Build better solutions while protecting your organization from legal and compliance risks. And learn how to think strategically about AI as a differentiation tool for your business. This summit is highly recommended for C-Suite leaders to learn as well as interact with each other and our sponsors.

It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
