Software Architecture

The perfect code doesn't exi... by Martin Hořeňovský Perfect code doesn't exist, right? There are always tradeoffs, complications and hidden complexities in the way. At least until now. I wrote the perfect C++ function, and I'll show it to you. What's more, I'll prove it to you, using all the different automated tools and approaches we commonly rely on during development: compiler warnings, static analysis, code coverage and others. In practical terms, I will showcase various tools we use during development; what issues they can catch, what issues they do catch, and why they protect us from Murphy, but not Machiavelli. Timetable: 18:00 Get together, setup, socialize 18:30 talk starts ??:?? talk ends, more socializing For those who want to join online here is the **[ZOOM LINK](https://us06web.zoom.us/j/87626916146?pwd=tE0xBia9Mnd8t2IGshtNpwyekQ9Zle.1)** While you wait why not join our **[DISCORD SERVER](https://discord.gg/EPMXNGuHXG)**

**Anotace přednášky:** AI nástroje píšu kód rýchlejšie ako kedykoľvek predtým. No rýchlosť bez kontroly kvality je len technický dlh vo väčšom meradle. V tejto prednáške sa pozrieme na to, ako LLM skutočne fungujú, ako inteligentne pracovať s kontextom a ako z AI dostať konzistentný, kvalitný výstup. Ukážeme si, ako používať AI na písanie testov, a prečo je verifikácia kódu kľúčová pre tímy, ktoré sa na AI pri vývoji výrazne spoliehajú. **Čo si odnesieš:** * Pochopíš, ako LLM a AI agenti skutočne fungujú pod kapotou * Naučíš sa pracovať s kontextom tak, aby si z AI dostával lepšie výsledky * Zistíš, ako písať čisté testy pomocou AI * Pochopíš, prečo je verifikácia nevyhnutná, keď AI píše väčšinu kódu **O řečníkovi:** Filip Hric začal svoju kariéru tým, že zdieľal to, čo sa naučil o testovaní. A nejako sa to rozbehlo. Jeho blog prekročil 2 milióny prečítaní, jeho kurzy absolvovali tisíce vývojárov a testerov a stal sa jedným z mien, na ktoré sa ľudia v oblasti testingu a quality engineeringu odvolávajú. Dnes spolupracuje s vývojovými tímami na tom, ako zabudovať kvalitu priamo do ich procesu, vystupuje na konferenciách po celom svete a snaží sa, aby éra AI nebola strašiakom pre tých, ktorým záleží na softvéri, ktorý naozaj funguje. Žije na Slovensku so svojou ženou a štyrmi deťmi. Beháva a hrá na gitare. Těšíme se - organizátoři [Pro:]Test! **POZOR**! Meetup probíhá na adrese: **Lihovarská 1060/12, 190 00 Praha 9-Balabenka**, NE v sídle Accentura na Holešovicích. **Setkání probíhá osobně na místě bez streamování. Pořizovat budeme záznam, který následně zveřejníme na našem [YouTube](https://www.youtube.com/@profesionalni_testeri).**

**Why are so many of us exhausted** — not from hardship, but from **the relentless pressure to do more, be more, optimize more?** Korean-German philosopher Byung-Chul Han has a diagnosis, and it might make you look at your own daily life differently. The Burnout Society is a short, sharp book that asks **why burnout, depression, and anxiety have become the characteristic experiences of our time — and whether the problem runs deeper than stress management or work-life balance.** Byung-Chul Han is a Korean-German philosopher based in Berlin who writes short, dense books diagnosing what’s gone wrong in contemporary life. He writes short, dense books — often under 100 pages — that draw on continental philosophy, cultural theory, and East Asian thought to diagnose something gone wrong in contemporary life. The Burnout Society, first published in German in 2010, was one of his early breakthroughs and one of his most widely read works. Join us for a close reading and open discussion. No prior knowledge of Han or continental philosophy is required. Participants are encouraged to read the text in advance and come prepared with a passage, a question, or a point of resistance.

**The most enjoyable way to meet new people without going clubbing! ✨** Tancheerna is unlike any dance event you’ve ever been to—there are no complex routines or staring at your feet. We hit the play button at 19:00 and start right away with fun group dances that are so simple, even children can do them. Later we blend in some easy couple dances mixing European classics, modern folklore, and smooth Latin rhythms. Our evenings are all about **great music, laughter, and the simple joy of moving together.** You don’t need a partner or any dance experience to join us. As long as you can sway to the rhythm, you belong. We use fun group mixers and rotate constantly, making it the perfect, fresh way to come alone and **connect with everyone naturally**. At 21:00, we wrap up the music and head to the nearby bistro for drinks and socializing. 📍 **Vítkov**: https://maps.app.goo.gl/JqyW62aohn18g5ZB8 **🕒 THE PLAN:** 18:50 - Arrival & Hellos **19:00 - The Music Starts! 🎶** 21:00 - Socializing at Bistro Vítkov 🍻 🎟️ **FREE ENTRY** 🌤️ **Weather Note:** This is an OPEN-AIR event! We dance only if the weather is nice.. 👟 Wear comfy sneakers or go completely barefoot. Pack a water bottle to stay hydrated and a hoodie when the sun goes down. Tančírna (pronounced tahn-cheer-nah) comes from the Czech word "tančit" (to dance) and literally means "a place for dancing". If you love to move and want to make new friends, simply show up on Friday and let’s dance!! 💃

Join us for Symposium! 🌞🌻🌳 In antiquity, a symposium was a gathering of friends who came together to recline around a shared table, where wine and conversation flowed freely into the night. Together, they would choose a topic and take turns speaking, listening, and laughing—guided by the rhythms of drink and dialogue. Inspired by this tradition, our Symposium has no set theme. It's an invitation to come together with other curious minds, to offer up questions or ideas, and to vote together on where to begin. Whether you're hungry for connection or simply seeking space to speak and be heard, you're warmly welcomed to join the conversation. Symposium will meet in parks throughout Prague, embracing the sunshine and pleasant weather while we have it. Bring a blanket or something to sit on. There’s no cost to join, but please bring a snack or drink to share, if you're able. Most of all, bring a curious mind and a willingness to learn from the insight of others. Feel free to bring a friend or two--also, children and friendly dogs are welcome! \*\*\* If the weather doesn't cooperate, we'll try to find an alternate venue—so keep an eye on the event chat or your email for updates. Also, despite the origins of the Symposium, our goal is not necessarily to get drunk and the organizer would encourage you not to come with that sole purpose in mind. :) The first 45 minutes of the event will be dedicated to simply getting to know one another, and we highly encourage you to join for this part. We will then vote whether to continue free conversation, to join together in a single conversation, or to split up into multiple groups. Afterwards, you’re welcome to stay or follow onto any spontaneous activity that unfolds. A note on attendance: If you need to cancel, please do so at least a few days in advance and update your RSVP accordingly. This helps honor the host’s efforts and makes space for others who would like to attend. Repeated last-minute cancellations or no-shows may result in being placed on the waitlist for future events.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

We have moved to guild.host. Look us up there. https://guild.host/events/buckeye-cocoaheads-rcavwd

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.
