Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 11:00 - quick intros. 11:15 - timer starts: write for 1 hour. 12:15 - (the end) chat / take off / keep writing / socialising. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you at To Theatron! What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons. Ideally come with your laptop fully charged in case there are not enough plugs for everyone. Other Important Details: -Theatron is close to the newly-opened metro station Dimotiko Theatro. The tram also stops right outside, and there are several bus stops nearby. -There is a parking service nearby on Kountouriotou 137 if you are unable to find a parking space. -Please thank our hosts by purchasing something.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
