F# Programming

**Python Meetup @ Sofia** продължава през април с пролетно настроение 🌼 и интересна тема .💡 Следвеликденско, традицията повелява да се съберем в края на месеца 📅, да научим нещо ново 📚, да споделим опит 🤝 и да си спретнем един networking 🧑‍💼, както си му е редът. 🗓️ Датата е **28-ми април**, а мястото е 📍**Barter Community Hub** 🏢. Започваме в ⏰ **19:00ч**. 🎫 Събитието е **напълно безплатно** ✅, нужно е само да потвърдиш присъствие тук 🙌 📢 Тема: **Prefect is almost Perfect!** ✨ 👨‍💻 Лектор: **Борислав Варадинов** 💭 **За какво ще си говорим:** Prefect е съвременен инструмент за оркестрация на работни процеси ⚙️ (workflow orchestration), създаден с мисъл за разработчиците 👩‍💻👨‍💻, или както самите те казват, „проектиран за хора“ 🤝. За разлика от много други оркестратори, базирани на DSL-и 🧩 или тежки конфигурации ⚠️, Prefect ви позволява да описвате workflows директно на Python 🐍 - по интуитивен, четим и лесен за усвояване начин 📖. Подходът е изчистен и елегантен: дефинирате flows и task-ове като обикновени Python функции, което намалява кривата на обучение 📉 и помага кодът да остане структуриран и консистентен.🧱 **🎙️ За лектора:** Борислав е страстен Senior Principal Engineer 🚀 и DevOps Advocate 🛠️ с богат опит в разработването, автоматизацията 🤖, инфраструктурата като код 🏗️ и управлението на конфигурации ⚙️. В момента допринася за иновативни проекти в Dell Technologies 💻. Има опит в работата с различни езици за програмиране, но през последните години истинската му страст е Python 🐍. След лекцията продължаваме в **networking частта** 🤝 с вкусна почерпка 🍕 (без козунаци 😄) и напитки 🥤, за които специално благодарим на нашите партньори от **[Waracle](https://waracle.com/)** 🙏. А някой от вас ще си тръгне и с малък подарък 🎁 от томболата ни. Очакваме те на **28-ми април** в **Barter Community Hub**!📍 Започваме точно в 19:00! ⏰ \-\-\- **Python Meetup @ Sofia, April Edition 🐍🌸** **Python Meetup @ Sofia** continues this April with a fresh spring vibe 🌼 and an exciting topic 💡 Post-Easter tradition calls for us to gather at the end of the month 📅, learn something new 📚, share knowledge 🤝, and, of course, do some proper networking. 🧑‍💼 🗓️ The date is **April 28th**, and the place is 📍**Barter Community Hub** 🏢. We kick off at ⏰ 19:00. 🎫 The event is **completely free** ✅ - all you need to do is confirm your attendance here 🙌 📢 Topic: **Prefect is almost Perfect! ✨** 👨‍💻 Speaker: **Borislav Varadinov** 💭 **What we’ll talk about:** Prefect is a modern workflow orchestration engine built with developers in mind - or as they say, designed for humans👩‍💻👨‍💻. Unlike many orchestrators built on DSLs 🧩or heavy configurations, Prefect lets you write workflows in plain Python 🐍 - intuitive, readable, and easy to pick up. It is a clean and elegant. You define flows and tasks just like normal Python functions, which reduces the learning curve and keeps your project clean and consistent.🧱 **🎙️ About the speaker:** Borislav is a passionate Senior Principal Engineer 🚀and DevOps Advocate 🛠️with extensive experience in development, automation🤖, infrastructure as code, and configuration management. Currently contributing to cutting-edge projects at Dell Technologies💻. He has experience working with various programming languages, but in recent years, his true passion is Python 🐍. After the talk, we’ll continue with a **networking session** 🤝 featuring some tasty snacks 🍕 (no Easter bread 😄) and drinks 🥤 — with special thanks to our partners at **[Waracle](https://waracle.com/)** 🙏. And some of you might even walk away with a small prize 🎁 from our **raffle**. We’re looking forward to seeing you on **April 28th** at \*\*Barter Community Hub!\*\*📍 We start sharp at 19:00. ⏰

Шест поредни месеца на спадове. Рекорд. А март най-после затвори на зелено. Видяхме ли дъното? На фона на геополитическо напрежение, несигурност и пазар, който дълго време изглеждаше изтощен, Bitcoin все пак завърши март нагоре. Дали това е знак, че дъното вече е зад нас? Или просто кратка пауза преди следващото движение? На следващия Sofia Crypto Meetup ще се фокусираме основно върху Bitcoin и големия въпрос: Видяхме ли вече най-ниските нива в този цикъл? Ще обсъдим: Какво означават шестте поредни месеца на спад и защо март е толкова важен сигнал за пазара? Кои други проекти имат шанс не просто да целеят, а да излязат по-силни от този период? Фокусът ще бъде върху това кои сигнали наистина имат значение и кои проекти могат да преминат през трудния период с реални шансове за следващия етап на пазара. Без излишен шум, без магически прогнози, само добър разговор, смислен анализ и достатъчно време за въпроси и дискусия. Елате, за да обсъдим дъното заедно... И за да можете един ден да кажете: I survived the bottom!

## **Fashion and Nigeria** **What can Europe learn from Nigerian culture and fashion?** *** Fashion designer and personal stylist **Boryana Vatova** traveled to Nigeria in 2018 and stayed there until 2020. The reason – an invitation to teach fashion at the *Learn and Work* academy, where she later became Head of the Design Department. Boryana shares: *"When I moved to Nigeria, I realized how different the culture is from the European one. At first, it was difficult for me to find the right way to communicate. That’s when I started studying human nature more deeply and understood that if you approach people with genuine interest and respect, cultural differences become a bridge rather than a barrier. Gradually, I built a very strong connection with my students and the people there. They accepted me deeply and authentically, which was a great gift for me. Nigeria taught me to notice the small things, to be grateful, and to value human connection above all else."* On April 26th, we invite you to a first-hand story with both professional and personal perspectives. Through many photos, videos, and engaging stories, we will explore the following topics: • The *Learn and Work* Academy and the educational model between Italy and Nigeria • The students – their ambition and attitude toward knowledge and fashion • Nigerian fashion energy – colors, silhouettes, textiles, symbolism • Cultural identity as the foundation of style • How elements of African aesthetics can be integrated into the European fashion context The idea is to show that cultural exchange is not one-way – it is a dialogue. At the end of the talk, you will have the opportunity to ask your questions to Boryana Vatova about her experience in Nigeria, its culture, and of course – her work in fashion. 📅 **Date:** April 29, 2026 ⏰ **Time:** 20:30 – 22:30 🍷 A complimentary drink is included in a cozy atmosphere. 🎟️ **Participation fee:** €15 Please contact us to reserve your spot. 📍 **Location:** AfriKaya Studio, Lozenets district, 56–58 Krum Popov St., 3rd floor *** **More about Boryana Vatova:** My name is Boryana Vatova and I am a fashion designer and personal stylist. Between 2018 and 2020, I lived and worked in Nigeria, where I taught fashion at the private *Learn and Work* academy – an institution based on an Italian-Nigerian partnership. I later became Head of the Design Department. This experience changed not only my professional path but also the way I communicate and build relationships with people. Nigeria taught me gratitude for the small things and deep respect for cultural identity. Today, this is reflected in my work – I build strong personal connections with the people I work with and believe that fashion is a bridge between cultures. 🌐 Website: [Boryana Vatova Official Website](https://www.boriannavatova.com/?utm_source=chatgpt.com)
