🌞 We are back with May meetup of AWS User Group Ljubljana! We will be hosting two outstanding speakers this month 🍻 \-\-\- Our eBPF specialist, Teodor Podobnik is back. This month he will present how he built an eBPF-based Firewall from scratch. A quick introduction to eBPF and a dive how to filter network packets on the kernel level. \-\-\- Sometimes admins get frightened when a pentester or auditor asks for their cloud credentials. Grega Prešeren will discuss why often times this is neccessary to get useful security guidelines and eliminate as much risks as possible. It is related to security testing methodologies, and results depend on chosen methodology. See you there! 🍻❄️ 📅 Agenda: * 🎤 Teodor Podobnik: Building an eBPF-based Firewall from Scratch * 🎤 Grega Prešeren: Security testing of cloud environments * 📍 Location: Sputnik, Tržaška 128, Ljubljana * 🕕 Date: May 28, 2026 at 18:00 🙏 Please confirm your attendance so we can prepare the space accordingly.

Join the Ljubljana Embedded Meetup on **May 28 at 18:00** at Visionect (Tržaška cesta 118, Ljubljana, 3rd floor), where Firmware Engineer **Aljaž Krašna** will share how Visionect navigated the cybersecurity certification process under the new EN 18031 standard. Cybersecurity compliance is becoming unavoidable for connected embedded devices. The EU Radio Equipment Directive now mandates that internet-connected radio equipment meet the requirements of EN 18031 — a standard that covers network protection, personal data safeguards, and protection against fraudulent use. For many embedded teams, the path from product to certification is anything but straightforward. In this talk, Aljaž will walk through Visionect's hands-on experience: what EN 18031 actually requires, how the team structured and prepared the technical documentation, what surprised them along the way, and what the certification process looked like in practice. The goal is to give other embedded teams a realistic picture of what's involved — not just the theory, but the real decisions, tradeoffs, and lessons learned. The meetup is open to the public and will be held in Slovene language. The lecture will be followed by a group discussion and socializing with snacks and drinks.

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!

SLO: Stopite stran od ekranov in uživate na soncu! Z veseljem vas vabimo na Slovenia Game Dev piknik, ki bo potekal v soboto, 30. maja, na RIC SAVA piknik prostorih v Ljubljani. Družili se bomo na Piknik prostoru #9 med 14.00 in 20.00. Odlična priložnost za klepet z drugimi razvijalci, izmenjavo idej ali preprosto uživanje na prostem. Če imate zložljiv stol, priporočamo, da ga prinesete s seboj, da si zagotovite udoben prostor za sedenje. S seboj lahko prinesete tudi kakšne igre za na prostem, kot so frizbi ali žoge, da bo vzdušje še bolj zabavno. Da bomo lažje organizirali hrano in pijačo, potrebujemo čim bolj natančno število udeležencev: prosimo, označite "pridem", če zagotovo pridete. Komaj čakamo, da se skupaj podružimo, povežemo in uživamo v sproščenem popoldnevu! ENG: Get ready to step away from the screens and soak up some sun! We are excited to invite you to the Slovenia Game Dev Picnic on Saturday, May 30th, happening at RIC SAVA piknik prostori in Ljubljana. We will be hanging out at Picnic Space #9 from 14:00 until 20:00, making it the perfect opportunity to catch up with fellow devs, talk shop, or just enjoy the outdoors. If you have a foldable chair, we highly suggest bringing it along to ensure you have a comfy place to sit, and feel free to bring any outdoor games like frisbees or balls to keep the energy going. To help us with food and drink procurement, we need an estimated headcount: please react with a "Attend" if you are definitely coming. We can't wait to see you all there for a great afternoon of networking and relaxation!

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.
