Comedy Club-Nacht für Ladies

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. # About Speaker Luka Matijević is a researcher at the Mathematical Institute of the Serbian Academy of Sciences and Arts, whose work bridges academic research and freelance engineering. He's drawn to identifying the right algorithm for a given problem — and to the kind of careful optimization captured by one of his favourite Futurama lines: *"When you do things right, people won't be sure you've done anything at all."* ## 📅 Event Details | | | | --- | --- | | 👤 **Speaker** | **[Luka Matijević](https://www.linkedin.com/in/luka-matijevic/)** | | 🕕 **Date & Time** | **27th of May (Wednesday), 6 pm** | | 📍 **Location** | **Beograđanka, Vidikovac, 22nd floor** | | 🏢 **Address** | **Masarikova 5** | | 💻 **Online** | **[C++ Serbia YouTube](https://www.youtube.com/@cppserbia)** | See you!

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

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! Ranked the #1 Ice Cream Shop in Columbus in 2024, this is the perfect place to kick off our Summer of Ice Cream and grab a sweet treat after the show! Their menu features an array of traditional, specialty and vegan shakes, hot cocoa, and more! You can check out their full menu here: [https://www.shakeno8.com/menu.php](https://www.shakeno8.com/menu.php) PLAN: We’ll plan for a 7pm-ish showing and will meet in the lobby area about 20 minutes before the show. Once showtime is announced, advance ticket purchase is advised! Once you have yours, please list your seat number in the Comments section of this event. We'll head to nearby Shake No. 8 immediately following the show! Should be a fun one, Dan

Welcome, readers! Our May read is **_Kindred_ by Octavia E. Butler.** The story follows Dana, a Black woman living in 1976 California, who is suddenly pulled back to a Maryland plantation before the Civil War. She learns her survival is tied to a white slaveholder’s son. Forced to move between centuries, she must endure the brutal realities of slavery while fighting to hold on to her identity. Tense, intimate, and unforgettable, Kindred explores how the past refuses to stay buried. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **drinks must be purchased at the bar.** Happy reading! 📖

The theme for May is Thriller. • The book we will be discussing is A Good Girl’s Guide to Murder by Holly Jackson. (determined by votes from April Book Club. Let me know if you'd like a free digital copy of the book) • This event will be at the main library. Feel free to come whether or not you've started or finished the book. • Small snacks will be provided. You're welcome to bring your own snacks & drinks too! Let me know if you’d like to volunteer to bring snacks or drinks for the group.
