Join us on April 29th at ToughTech for an event exploring real challenges in modern software development. Dive into the trade-offs of distributed systems and eventual consistency, and learn how to turn AI into a practical part of your everyday development workflow. Connect with others, exchange ideas, and gain insights you can register right away - don’t miss out! Agenda: * **18:30 "Eventual Consistency: The Troublesome Trade-Off Behind Distributed Systems"** **by Andrius Ragelis** "No matter the architecture, data can become stale - and sometimes lead to costly issues. Fast, available, distributed - and occasionally wrong (for a moment). Let’s explore why these inconsistencies happen, how they manifest in real systems, and how to design around them effectively." * **19:10** "**From Hype to a Workflow: Integrating AI into the Everyday Work of Development**" **by Vidmantas Varnas** "Artificial Intelligence is becoming a core part of modern software development, yet many teams still lack practical ways to use it day to day. The key is finding where it truly adds value. From code and documentation to planning, debugging, and knowledge sharing-along with the common challenges and pitfalls." * **20:00 Bytes & Bites** The opportunity to become a student or a lecturer in disguise as you mingle, snack and connect with fellow tech enthusiasts is all yours. Don't worry about grades - here, laughter and nods are the ultimate measures of success! **Tech info about ToughTech:** * ToughTech journey will start at 18:30 - (guests will be welcome to enjoy snacks and network until 21:30) * The event will be conducted in LTU language * [REGISTRACIJA](https://forms.gle/5CEwREBFGFWYpMKW9)

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.
