Free In-Person Events: How to Let Go of the Past and Move Forward
The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience.
And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree.
In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again.
Examples of painful experiences include:
* A broken relationship or divorce.
* Death or loss of a loved one.
* Death of a pet.
* A sudden shock or bad news.
* A betrayal.
* Being part of an abusive relationship.
* A bad injustice.
* Loss of a job, position or business.
* A grave illness or injury.
The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is sponsored the Dianetics & Scientology Self-Improvement Center.
Board games at The Forge
The Forge does have a full bar and kitchen. There is no cover charge but they do request all attendees to purchase a minimum of ~$20 per person. Soft drink refills are $1 each. Please support our hosts so we can continue to provide great events for the group!
The Forge has a large library of games available for us to enjoy. Hosts and regulars will also provide numerous popular games but please bring any games you would like to teach and/or play.
Doors open at 6, and we expect gaming to be rolling by around 630. Please promptly end your games and clear out the space at 10pm when the bar closes.
We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area.
Parking can be challenging. There is a parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.

Columbus Comedy Improv Meetup at Gresso's!
Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games!
The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime!
Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.
