Здравейте, WordPress хора! Както знаете, благодарение на Matt Mullenweg и Mike Little, на 27 май 2003 г. един млад проект с отворен код направи първите си стъпки в света - и ето ни 23 години по-късно, все още влюбени в него. Двама души го създадоха, но хиляди доброволци, разработчици, дизайнери и ентусиасти по целия свят го превърнаха в това, което е днес. Затова на 27 май 2026 г. отново ще се съберем в София, за да вдигнем тост (и хапнем парче торта) за рождения ден на любимата ни платформа! Какво ни очаква? Среща с хора, които говорят на нашия език - този на темите, плъгините, къстъмизациите и късните нощи в WordPress редактора. Очакват ни разговори, хапване, торта и онова специално усещане, когато общността се събере на едно място. Докато ние празнуваме в София, хиляди WordPress ентусиасти по целия свят правят същото – а ние сме част от тази голяма картина. Без значение дали си разработчик с 15 години стаж, дизайнер, който прави първия си сайт, блогър, агенция или просто човек, който обича отворения код – има място за теб на тази маса. Малко повече инфо: 🎟️ Събитието е напълно безплатно. Единственото, което трябва да направите, е да се регистрирате в събитието в Meetup.com. 📍 Мястото? Добре познатото ни Sky Beauty Lab! 👕 Донеси любимият си суаг! Извади от гардероба най-готината WordPress тениска, шапката с логото, чорапите с Wapuu – каквото имаш. И не забравяй да публикуваш снимки с хаштаговете #WP23 и #WP23Sofia, за да покажем на света как празнува българската общност. Благодарности: Това парти нямаше да е възможно без партньорите ни, които стоят зад WordPress Sofia Meetup и общността ни вече години наред – [SuperHosting.BG](SuperHosting.BG), [Delta.BG](Delta.BG), [Jump.bg](Jump.bg) и [JetHost.BG](JetHost.BG). Благодарим ви, приятели! <3 Заредете доброто си настроение, отворете календара и си запазете датата. За тези, които не знаят: месечните срещи на WordPress Sofia Meetup събират десетки хора (независимо дали са професионалисти или абсолютно начинаещи), които по някакъв начин са свързани с най-използваната система за управление на съдържанието в света. Те са напълно безплатни и отворени за всички, които обичат WordPress - единственото нещо, което трябва да направите, за да присъствате, е да се регистрирате в събитията тук. Очакваме ви! Фори, Ники, Явор

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!

There will be announcements and presentations followed by some social networking Let's continue the conversations with good vibes and friends. All are welcomed from all ages and backgrounds to this public event. If we can, we'll be streaming or uploading the video later via our COGG YouTube channel here: [https://www.youtube.com/@TheCOGG/streams](https://www.youtube.com/@TheCOGG/streams) (Also please do subscribe if you have not done so!)

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. 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

The Forge does have a full bar and kitchen. There is no cover charge but they do request all attendees to purchase a minimum of ~20 per person. Soft drink refills are 1 each. Please support our hosts so we can continue to provide great events for the group! The Forge has a large library of games available for us to enjoy. Hosts and regulars will also provide numerous popular games but please bring any games you would like to teach and/or play. Doors open at 6, and we expect gaming to be rolling by around 630. Please promptly end your games and clear out the space at 10pm when the bar closes. We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area. Parking can sometimes fill esrly. There is additional parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.
