LFU looks deceptively close to LRU: both caches evict the "least useful" item. We'll look at how the ordering rule affects data structure design. We'll discuss the algorithmic tradeoffs behind LFU and compare different implementation strategies, ending with benchmarks in C++ and Rust. Date and time: **25th of June (Thursday), 6 pm** Location: **Beograđanka, Vidikovac, 22nd floor** Address: **Masarikova 5** Online: **[C++ Serbia YouTube](https://www.youtube.com/watch?v=PwmFvXE_K9I)** To join the community discussions, we are on: * [Discord](https://discord.gg/VDUn8YtHw8) * [Telegram](https://t.me/+l7NS0GrslBMwNzI0) * [Website](https://www.cppserbia.org/) See you!

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!
