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.

We'll get in around 4 miles at Three Creeks Metro Parks, primarily natural trails. 17-18 minute miles, no one left behind, and faster walkers are free to lead out. Optional lunch after! If you're joining for hiking all the metro parks, this is the sixth one!

We will have our certified mediums available and you can receive 3 10-minute readings for $20. To keep you safe, we will be following all CDC and Health Dept. guidelines at our psychic fair today. Sitters and readers required to wear a mask. We will maintain a minimum of 6 foot physical distance during readings. Please, if you can, bring your own portable chair to use during your readings. Please note that we are at our wonderful new home at Unity of Columbus, 4211 Maize Road, Columbus, OH

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. 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!

**How to Get Off-Market Deals With Direct-to-Seller Marketing** Want to learn how to get off-market deals through direct-to-seller marketing without relying on agents, wholesalers, or the MLS for consistent deal flow? That is exactly what we are covering at this next Columbus Investors Club Meetup. Get Your Free Ticket **[HERE](https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp)**[ ](https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp)🎟️ Most investors who try to do off-market deals make the same mistake: they throw money into a marketing channel, pray that it works, and hope a deal comes out the other side. There is no real strategy, no clear math, no tracking, and no process to know what is actually working. At this meetup, we are going to break down how to reverse engineer direct-to-seller marketing using our SCALE framework so you can approach your marketing with more clarity, confidence, and consistency. We will cover how to think through inbound, outbound, and free marketing channels, how to choose the right channel for your goals, how to run the numbers before you spend, how to allocate the right budget, how to launch the campaign correctly, and how to evaluate and track performance so you can make better decisions moving forward. **SCALE Framework:** **S –** Select the right channel **C –** Calculate the numbers **A –** Allocate the budget **L –** Launch the campaign **E –** Evaluate and track it **What We’ll Cover** * How to get off-market deals through direct-to-seller marketing * How to stop guessing and start reverse engineering your marketing * The difference between inbound, outbound, and free marketing channels * How to choose the right channel for your business and market * How to calculate the numbers before launching * How to allocate a budget based on goals, not emotion * How to launch and track a campaign the right way * How to create more consistent and predictable deal flow **Date:** May 28, 2026 (Thursday) **Time:** 6 - 8pm EST **Location:** Ohio Brewing Company, 421 E 2nd Ave, Columbus, OH 43201 **Save Your Seat** → https://www.eventbrite.com/e/how-to-get-off-market-deals-with-direct-to-seller-marketing-tickets-1987845260686?aff=cicmeetupapp **FREE DRINKS & FOOD PROVIDED!** **About Columbus Investors Club** The Columbus Investors Club is a local meetup for real estate investors, aspiring investors, contractors, vendors, lenders, realtors, and other professionals who want to grow in the Columbus market. The goal is to create real connection, real opportunity, and real growth by getting the right people in the room.
