*Is privacy a fundamental human right?* *Should privacy ever be sacrificed for security?* *How does surveillance change how we behave?* *Is privacy necessary for democracy?* This time we will be discussing the **right to privacy** in the relative privacy of an upstairs room of a North London pub! No walk this time (due to a broken toe)! Instead we will head indoors and experiment with a different format - a talk and discussion session. Meet at 2pm at the Star of Kings pub in King's Cross, upstairs in the green room. If you want to do some reading on the subject I recommend **The Right to Oblivion** by Lowry Pressly: https://www.amazon.co.uk/Right-Oblivion-Privacy-Good-Life/dp/067430490X A YouTube video on the same book by Unsolicited Advice. https://www.youtube.com/watch?v=J5sx5nGNIyc If you have any other recommendations on the subject feel free to post in the commends below. There will be a short presentation then group discussions. This group encourages friendly, constructive conversations rather than confrontational debates; so give everyone space to talk, be respectful and actively listen to others. It's not about 'winning' a debate but about expressing your opinion and learning about other people's views. Admission £5, if you are a student, unemployed or retired then you can attend for free. You can pay in cash or card on the walk or online with this link: [https://pay.tide.co/products/philosophy-kfDyHrXZ](https://pay.tide.co/products/philosophy-kfDyHrXZ) **This event is supported by the Royal Institute of Philosophy.**

A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it.

Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part!

This group is brought to you by the Dianetics and Scientology life improvement center.

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.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
