Hello, Jakarta Writer! **Are you a member of [Jakarta Friends](https://www.meetup.com/jakarta-friends/) yet?** Want to see **pictures** of past events? **[Take a look here!](https://www.meetup.com/jakarta-creatives/photos/)** And feel free to upload a few pictures you might take at the event 😊 JakWri (former Jakarta Writers) and JakFri is **the** biggest, oldest, most active, and most inclusive MeetUp community in Jakarta… and we invite you to join us for this **BOOK CLUB discussing "Heart of a Dog" 🐕 by Mikhail Bulgakov!** Everyone is always welcome to join our events. Our community is all about creating authentic in-person connections in this urban jungle. Come as you are... it’s the best version of yourself. **ABOUT THE EVENT** The idea is very simple: we will meet and discuss the book. Everyone will receive a copy of the book as PDF beforehand **for free** (which we kindly ask not to share with everyone - this book discussion is for educational purposes). Reach out to the host to receive the PDF, and feel free to ask any question in the discussion section of the event page. Everyone is encouraged to read the short book (in English, about 300 pages) beforehand to participate to the discussion. Coming without having read the book is possible, but just half the fun. The host will give a short introduction about the book and guide through the discussion, which will be very informal and fun. Everyone is encouraged to share their thoughts and ask questions. This event is **introvert friendly**! No one will be put on the spot or forced to speak. Just join and share your passion for literature, no matter how much you read. This is a dream event for anyone who wishes to take a deep dive into literature and have a fun, social lunch time. Our book club will be in English. Everyone's English level is OK as this is a nice occasion to practice English in an informal and welcoming setting. **ABOUT THE BOOK** A parody on the "New Soviet Man" and eugenics, Bulgakov's satirical and biting novella remains one of the more odd and fascinating takes on Bolshevism. Sharik, the dog, finds itself rescued by the brilliant and arrogant Profesor Preobrazhensky from the streets full of its natural enemy: the proletariats. One day, the Profesor ends up experimenting on the pampered and fattened Sharik as part of his research on rejuvenation, only for the operation to take a sharp and bizarre turn. It's best to enter into this book blind, bearing only the questions of which one is more horrifying: the heart of a dog or the heart of a man. Discover more about the book [on Goodreads](https://www.goodreads.com/book/show/113205.Heart_of_a_Dog)! **We have had several Book Clubs before!

**Caller: Kim Thompson** **Band: Full Moon Country Dance Orchestra** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.

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.
