Software Development

**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).**

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)**

**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** *July Meeting - Lightning Talks!* Lightning talks are very short presentations on a topic of your choice (must be related to .NET). Talks should be 15-20 minutes in length and include minimal slides and quick demo (no live coding please). There will be 6 slots available! First come, first serve! **YouTube Link** TBD

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.

**Hello Columbus!** **The community is buzzing and growing well. We are thrilled to bring our fourth BrowserStack QA Meetup on Thursday, July 9th!** We are creating a space for deeper insights, meaningful connections, and a vibe you won't want to miss. **What to expect:** * **Connect:** Network with Columbus' top engineering and QA minds. * **Learn:** Real-world tactics and trends you can use immediately. * **Enjoy:** Food, drinks, and great community spirit. **Agenda** * **Two Roads Diverged in a Wood: Docker Compose vs. Kubernetes** by **[Doug Reeder](https://www.linkedin.com/in/pdouglasreeder/)** **RSVP Essential:** Space is limited, and we want to ensure a great experience for everyone. **RSVP now to secure your spot!** 📍 **Venue:** Leading EDJE, 6515 Longshore Loop, Suite 300, Dublin, OH 43017 📍 **Free Parking:** 6725 Longshore Street, Dublin, OH 43017 📅 **Date & Time:** July 9, 6:00 PM **Stay Connected!** Want to continue the conversation beyond the meetup? Join our **BrowserStack Discord Server** to get updates, connect with fellow QA professionals, and be part of an ongoing discussion. **Don’t miss out—click below to join!** 🔗 [\[](https://discord.gg/6SdCyWTNyW)**[Join the BrowserStack Discord Server](https://discord.gg/6SdCyWTNyW)**[\]](https://discord.gg/6SdCyWTNyW) **A Few Notes:** ✅ This is an **in-person event** ✅ **RSVP does not guarantee a seat** – A confirmation email will be sent one day before the event. **TALK ABSTRACT:** Docker Compose and Kubernetes are two of the most popular tools for running containerized applications. Their feature lists are similar. Architects and senior developers need to know how their different paradigms lead to unexpectedly different experiences in production.
