**📌 Програма за 25 юни 2026:**
* 19:00 ч. - Начало и въведение

* 20:45 ч. - [Vladimir Atanasov](https://www.linkedin.com/in/vladimir-a-18968395/) @ [EGT](https://www.linkedin.com/company/egt-digital?originalSubdomain=bg) \- It's about Time

**Deyan Vuchev** е Cybersecurity Architect в SumUp с 15+ години в сигурността и силен опит в SIEM/XDR, автоматизация и облачна сигурност. Презентацията му показва как в SumUp контролират и наблюдават използването на AI tooling и agentic решения в реална fintech среда.
**Denitsa Taneva** е Senior Security Engineer в WiseBee с фокус върху cloud security, vulnerability management, product security и AI рискове. Ще предложи нов поглед към приоритизацията на уязвимости — защо "открито" не значи "експлоатируемо".
**Vladimir Atanasov** е Security Architect в EGT с над 10 години в сигурността. Ще разгледа пресечната точка между времето и сигурността — с практически примери от defend и attack перспектива.

Least Frequently Used Cache: The Annoying Little Brother of LRU
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)**
