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

Marketingaši se često susreću s paradoksom da imaju više kanala i alata nego ikad, a sve je teže postići opipljive rezultate.

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.

**Kako Gradska uprava može poboljšati život građanima uz pomoć umjetne inteligencije (AI)?** Koristi li se AI u svakodnevnom radu održavanja sigurnosti u prometu i održavanju infrastrukture? Kako koristiti AI tehnologiju u suradnji sa ostalim gradovima, ali i EU zemljama i tvrtkama? **Zoran Cetinjanin**, **Mario Novosel** i **Marino Ivasić** iz Gradske uprave Grada Karlovca, pokušat će ukratko prikazati rješenja koja se koriste kako bi svima nama podigla kvalitetu, a uz pomoć najnovije tehnologije. Zoran i Mario kao IT-evci sa više od 20 godina rada u Upravi (Katica za sve i oni koji odrađuju sve AjTi probleme u Upravi) stvorili su image Grada Karlovca kao jednog od najinovativnijih „SMART“ gradova u HR. Kako i kojim tehnologijama - pokušat će prezentirati dio rješenja. Marino koji upravlja prometom u našem gradu (ali uz pomoć najnovijih tehnoloških rješenja) pokušat će vam dočarati taj „underground“ svijet da prikaže koliko mu ta tehnologija pomaže da rješava svakodnevne probleme, ali i djeluje proaktivno. Prezentacija ima cilj da potakne ostale na razvoj različitih rješenja kako bi jednog dana imali naš **#KaFrameWork** za AI. Svi ste pozvani da sa svojim idejama, pomognete u daljnjem razvoju, a interesantno će biti čuti i na koji način razvijamo suradnju sa ostalim članicama EU.

Join us as we get together to see Paul Rudd in the latest comedy-drama-musical from John Carney, POWER BALLAD! The film follows a washed-up wedding singer, a fading boy band singer and a stolen hit song. Here’s a description, trailer and plan for this event: DESCRIPTION: Rick, a washed-up wedding singer, and Danny, a fading boy band star, bond over music and a late-night jam session. When Danny turns Rick's song into a hit, Rick sets out to reclaim the recognition he believes he deserves. Power Ballad is written/directed by John Carney, the master of the modern musical and creative mind behind Once, Begin Again and Sing Street! 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!
