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!

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.

*This event features presentations in both English and Bulgarian.* Силен старт на крипто лятото! Миналия месец се надявахме, че сме оцелели след дъното. Този месец видяхме токени, които се покачиха с до 50%. Изглежда не сме сгрешили. След месеци на спадове, несигурност и пазар, който дълго време изглеждаше изтощен, нещо най-после се размърда. И не само на графиките. Имаме три добри новини за този месец: Първо, пазарът показа зъби. Второ, САЩ продължават да бутат напред с добра крипто регулация. Трето (и може би най-забавното): Prediction Markets се оказаха толкова успешни, че България реши да ги блокира (за първи път още през февруари). Когато регулатор бърза да забрани нещо, обикновено това е знак, че там се случва нещо интересно. На следващия Sofia Crypto Meetup ще обсъдим: Кои токени се представиха най-добре и защо. Какво всъщност представляват Prediction Markets и защо толкова много хора (и държави) говорят за тях. Какво може да очакваме през лятото - кои са реалните сценарии, а не магическите прогнози. Никакви празни приказки, никакви обещания за бързо забогатяване. Просто разговор по същество, добър анализ и достатъчно време за въпроси и дискусия. Елате да го отпразнуваме заедно. Дъното е зад нас, лятото е пред нас, а разговорът ще бъде интересен. Очаквайте и много специален гост!

**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** https://youtube.com/live/BltmWMH1zG0?feature=share

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.
