Numerical Analysis

As noted last week, it's now "Summer-Time" for our run, as daylight has returned, and will be with us of many months. whilst the temperatures may not yet be climbing, Storm David is behind us, and this week, the run will terminate in **Mother Reilly's in Rathmines**, which of course does have a wonderful Beer Garden, although it may be the next visit before that can be enjoyed. But never fear, it also has a welcome fireplace, and great beers to replenish after a run. Note of praise to those from the group that recently paid a visit to Berlin for a wee run around that city - Congrats to all who took part over there, and enjoyed the Beers afterwards. For newcomers, our Group Runs are great fun, safe for all, and once the run is complete, we can share a beer, have a good chat, make new friends, and look forward to the following week.

Yoga Classes with Hannah Fitzpatrick on Wednesday evenings at Anam Ashram, Tallaght, 7pm-8:8.30pm.

We will end with a guided deep relaxation. Contact Hannah for more details and for booking on 083-4863900

Join us for a lovely evening of music and song in a relaxed, supportive space. Whether you're a seasoned pro or just starting out, all levels of musicians and singers are very welcome. We are adding a few sing along songs to our Wednesdays session. You will still get the opportunity to sing as usual we are just adding some sing along songs to add something new to the session. see comment section below for the sing along song list. ​Performers: Space is limited to 10 performers to ensure everyone gets their time in the spotlight. Please secure your spot by booking through the app! ​Listeners: If performance spots are full, we’d still love for you to come along, listen, and soak up the atmosphere. It’s a wonderful way to build confidence and get a feel for the session. ​The Details: There is a small €2 kitty fee. As the venue hosts us for free, we kindly ask that you support the bar by purchasing a drink or two. ​A Note on Parking: The car park directly outside is convenient but strictly monitored, so please double-check the rates to avoid a €125 unclamping fee! For a stress-free evening, there are several other parking options within a 5-minute walk, including the Tesco car park (which is usually free after 6:30 PM, but do check the signs!).

## Details The title of the event is a paradox! Read in silence and then discuss with like-minded folks! :-) 📝 **How does this work?** We will meet in the Bartley's Restaurant area from 7:00 PM to 8:15 PM for silent reading and followed up by discussion. **During silent reading, you're expected to remain silent and read.** Please bring your headphones and refrain from the discussion during the first one hour in the area. 👥 **Socialising** After an hour, at 8:15 PM, we'll discuss and socialize about the book you're reading. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! Feel free to join at any point during the event. The event is indoors, hopefully, we can continue the tradition of the silent reading in the winter! **📌 Helpful Tips and Notes** * Bring headphones to block out surrounding noise * I will post a comment on the event page when I arrive to indicate where we're seated, so everyone can find us * If you prefer to skip the silent reading, you can join directly at the bar at 8:15 PM ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. It may be small but don't hesitate to reach out to me. Looking forward to meeting you all 😊

Get over the mid week slump and come down to meet some new faces and relax. We try and go to a different bar every week and you can join us anytime after 18:30. **How to find the group?** \*We have an area reserved just for us so if you are new and unsure please ask any of the bar staff for the area reserved under the organisers name or if completely lost on the night please contact the event host and they'll come and find you. **How does it work?** \*After finding the group either the organiser will approach you and ask if you are looking for the meetup or you can just ask anyone "Is this the meetup?" and normally that is a great conversation opener to join the group. After that it's up to you what you make of the event. That is pretty much it. Easy right? We normally encourage people to stand as it's much easier to mingle that way. **Nervous about coming to the event?** \*While it's quite intimidating meeting a bunch of strangers from the internet we are a very welcoming group. We normally look out for new people and remember that everyone in the group has been new in the group at one point. If are you'd like extra help just contact the event host on the night. **Interested in helping out?** \*Let me (Éamonn) know as it would be greatly appreciated. **Something happened?** \*Please report it to the organiser as we cannot do anything to prevent it from happening again if we don't know about it. Even if it's something small please let the organiser know as they are probably unaware. We aim to have the location up by Monday afternoon before the event. The bars we go to are all based in the city centre. **See you on Wednesday!**

**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.

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.
