Concurrent Programming

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.

**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.

We are a group of runners who meet most weeks for a run around the beautiful Vltava River's edge. You can bring your running shoes straight from the office/home office if you don't have time to stop at home. There will be a place to put your bags in the Cafe. We will run about 9 km along the river and have a drink afterwards. Paces vary! We will meet in the square near Kavarna Liberal (Hermanova 6), near the Vltavska metro/tram stop at 6:30 on Wednesday. See you there!

NOTE THE TIME CHANGE TO 9AM Hi All, Come and join us for social running and a coffee! We meet at the main gate of Vystaviste - tram stop Vystaviste Holesovice. We will run in Stromovka. Usually we run around 50mins and it is up to everyone how many kilometres. We welcome all levels of runner. We can all run together or, if there is more of us, we can split into groups and at the end of the run we all meet close to the starting point to go for a coffee to a nice local coffee place (where they also sell cakes and great chocolate). If the weather is great, we can also just sit in one of the outside coffee placces in Stromovka and enjoy the sun. This is where we meet: http://photos2.meetupstatic.com/photos/event/7/7/3/1/600_447930513.jpeg

**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!! 💃

Welcome to the international Café Philo in Prague. We meet every first Saturday of the month in the cosy [Café Millème](https://store11473398.ecwid.com) in the center of Prague. We choose a participant randomly, by lottery, who then has the privilege to determine the topic of our discussion. We will reflect, ponder and exchange arguments until our brains are on fire. Philosophy isn't just something for universities, it is a way to open your mind to new thoughts and questions. No application is necessary, there is no entrance fee and there are no prerequisites for participating, except curiosity and respect for other people. We meet from 17:15 until 18:45 to follow together the white rabbit into the wonderland of philosophy... More information about me under this [link](https://sophonautik.ch/english/).

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.
