Hi everyone! Join us for RubyZG May meetup. We have 2 great talks lined up: Vlado will show us how to go beyond the default Rails 8 PWA setup and build apps that work offline, and Bruno will talk about using more database features in Rails with Scenic and FX. This is also our first meetup at a new location: [Pogon, in Mislavova street](https://www.pogon.hr/rezerviraj-prostor/mislavova/opis/). After the talks, we're going for drinks nearby. There are a couple of interesting options around, including Monocycle, Boogie Lab and Branimir Mall, so we can vote on the favorite after the formal part of the meetup. See you at Pogon! \*\*\* **Beyond manifest and service-worker: Rails PWAs in Practice** by [Vlado Cingel](https://www.linkedin.com/in/vladocingel/) Rails 8 ships with PWA support out of the box, but the built-in /manifest.json and /service-worker.js routes are just the starting line. In this talk we'll go from that default to a fully offline app: caching pages, storing structured data and building forms that work without a network. **Database Features, the Rails Way** by [Bruno Sutic](https://www.linkedin.com/in/brunosutic/) Rails makes database work simple, but sometimes the right solution lives closer to the database. In this talk we'll look at Scenic and FX, two gems that help us use views, functions and triggers in PostgreSQL while keeping the workflow familiar to Rails developers.

Hey everyone! Join us for our next meetup on **May 27th** starting at **18:00** at a new venue - **Pogon Mislavova** (Kneza Mislava 18). We'll have an interesting talk by our own Vitaliy, followed by our usual networking. Afterwards, we'll either stay at Pogon or head to a nearby bar (Canopy Bar sounds like a good option). \*\*\* Electron in Production: Building Efficient Desktop Apps with Native Modules by **Vitaliy Yunikov** VS Code, Slack, Figma, Linear, Notion — a lot of the desktop apps web developers use daily - are all Electron. Electron also has a reputation for being slow and bloated. Both are true: a well-built Electron app feels native, a default one doesn't. This talk covers what production Electron teams know that the docs don't tell you. We'll go through the process model and what each process costs, the security defaults you need from day one, the JS-side performance moves that buy back the memory Chromium charges, and what happens when pure JavaScript stops being fast enough - going native with N-API, including the data, threading, and memory contracts that surprise even experienced JS developers. Hope to see you there! Marcela

Join us for a casual drinkup at Dribbling Food&Caffe. Come for drinks, stay for conversations (about programming). Everyone is welcome, don't be shy! Hope to see you there!

Combinatorial optimization problems arise across logistics, scheduling, and engineering, and C++ remains a language of choice when performance matters. This lecture takes a practical look at solving such problems in C++, using the Electric Vehicle Routing Problem as a running example. We begin with an exact solver, formulating the problem as a mixed-integer program and trying to solve it through GLPK's C API directly from C++. Exact methods, however, quickly hit their limits on real-world instances. The second half of the talk turns to metaheuristics: how they are designed, why C++ is particularly well suited for implementing them, and what design choices matter most in practice. We'll walk through a concrete implementation, touching on data structures for fast neighborhood evaluation, generic algorithm design with templates, and the performance considerations that separate a prototype from a production-ready solver. The goal is not to advocate for one approach over another, but to show how C++ supports the full spectrum of optimization techniques.

The aim of this group is to get together and practice our German. Doesn’t matter if are a beginner or a native speaker. The goal is to speak and improve our German. Everyone is welcome! If the weather is good, look for us in the Biergarten. Pro Tip: Get there before 6:00 for happy hour pricing.

It stars Paul Rudd, Nick Jonas, Peter McDonald, Marcella Plunkett, Havana Rose Liu and Jack Reynor. BUZZ & ACCLAIM: The film premiered to rave reviews at this year’s Dublin International Film Festival where critics call it “a sure-fired crowd-pleaser” that “just might be the feel-good hit of the year!” Others say, “Paul Rudd delivers a career-best performance in this charmer” that’s both “hilarious and deeply moving!” SUMMER OF ICE CREAM, VOL 2: SHAKE NO. 8!
