Come and join us for a **Free Guitar Learning Class**! Something exciting for this weekend’s guitar lesson! The class will start at 18:00 as usual and right after we will have snacks and tea and watch a short film made by a friend of mine. The movie is about Azerbaijani rock band called Coldunya (founded in the 1990s) and showcases their road to fame and current life of the band members. I haven’t watched it yet, so looking forward to sharing this moment with you. I hope to see you! And enjoy your Easter holidays! **General description of the class:** Our class is all about beginning stages: playing chords, tabs, holding guitar properly and getting the fingers ready to play. We will have enough time to cover the basics, discuss what we would like to improve and get playing at least one simple song! I also speak Hungarian, so if there is anyone who doesn’t understand English, I will translate on the go. Any newcomers are welcome and I will help you to get started and develop together with others. **What to bring:** A pen and notebook, so you can take notes as needed. Guitar (if you don't have one, you can use mine during the class, but definitely you should get a guitar later if you want to learn guitar properly). This event is totally **free of charge**, but you are welcome to donate, which helps me, the organizer, to cover the bills. Feel free to **bring your friends**. We have enough space! **I recommend joining our Telegram channel** to get notified about announcements or any cancellations: https://t.me/budapestGuitarClub

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
