WordPress на 23: Време е за парти! 🎉
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

C++ for Combinatorial Optimization: From Exact Solvers to Metaheuristics
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."*

Sharp Objects - Gillian Flynn
Join us for Sharp Objects by Gillian Flynn!
Fresh from a brief stay at a psych hospital, reporter Camille Preaker faces a troubling assignment: she must return to her tiny hometown to cover the unsolved murder of a preteen girl and the disappearance of another. For years, Camille has hardly spoken to her neurotic, hypochondriac mother or to the half-sister she barely knows: a beautiful thirteen-year-old with an eerie grip on the town. Now, installed in her old bedroom in her family's Victorian mansion, Camille finds herself identifying with the young victims—a bit too strongly.
Dogged by her own demons, she must unravel the psychological puzzle of her own past if she wants to get the story-and survive this homecoming.

Wine Tasting - Newcomers Night
This is "***New Members Night***." If you are one of the many folks on the fence about coming to your first wine tasting with the *Hilliard Wine Club*, this is the night to come. There will be many other new people, so you won't be alone. And the regulars will be there to help make you feel welcome. We're a relaxed and warm group. We hope to see you.
**SIDE NOTE:** New members are welcome to ALL our Friday night wine tastings, but this night is a special overture to those who don't want to feel that they are the only new person in the room. Don't worry. You won't be. And don't hesitate to RSVP to other events.
**OLD MEMBERS NOTE**: Hey Old Members! You're not excluded from this event. We expect to see you there to help make the new members feel welcome.
**Sample 4 different wines** this Friday for $15 (*Cash or Venmo only please*). Glasses are provided. Bring a snack to share. Bring a bottle to share if you care to. See all the details below for the Hilliard Wine Club Wine Tasting. In Person. In Real Life. Actual Wine from glass bottles with corks and everything.
**Wine**: Tastings will be $15 for four samples as always. And you are welcome to bring a bottle of your favorite wine to share with others. Participation in the wine tastings is optional. But since you’re going, I will buy enough wine to cover you. If you bring your own wine and do not participate in the tasting you will only pay $10 to cover the door charge.
**Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby.
**Glasses**: …will be provided. Please note that after the wine tasting, the glasses need to be returned to the boxes at the service table. Please be gentle, our glasses are fragile. Uh, they are made of glass!
**Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing.
**Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions.
**Extra Wine**: After everyone has had their samples, we remove the pouring spouts and any remaining wine is poured freely to whomever wants it. I hate having leftover wine.
**Queen of Hearts**: The Queen of Hearts raffle is a fundraiser for the club and a Barnum and Bailey type extravaganza - minus the dancing ponies, clowns, and actual circus. Bring your ***cash*** as the Queen does not accept American Express or other plastic.
**After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee.
Again, We look forward to meeting new members and reuniting with old friends.
Sincerely, ***Paul Uttermohlen***,

Ensuring Software Quality in the world of AI Developers - Matt Eland
**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
Karaoke + Freestyle (bring wine)
**Karaoke Night**: Bring your glee club friends. Enjoy a flashback to your choir days. No chorus line. It's all you baby. Sing. Shout. Scream. Lip sync if you need to. But do show up and do have a good time.
**On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\.
**Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours.
**Glasses**: …will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass!
**Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing.
**Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions.
