In 2025, Hungarian author László Krasznahorkai was awarded the Nobel Prize in Literature "for his compelling and visionary oeuvre that, in the midst of apocalyptic terror, reaffirms the power of art". Let's see what that looks like. *GoodReads Summary:* A powerful, surreal novel, in the tradition of Gogol, about the chaotic events surrounding the arrival of a circus in a small Hungarian town. The Melancholy of Resistance, László Krasznahorkai's magisterial novel, depicts a chain of mysterious events in a small Hungarian town. A circus, promising to display the stuffed body of the largest whale in the world, arrives in the dead of winter, prompting bizarre rumours. Word spreads that the circus folk have a sinister purpose in mind, and the frightened citizens cling to any manifestation of order they can find - music, cosmology, fascism. The novel's characters are unforgettable: the evil Mrs. Eszter, plotting her takeover of the town; her weakling husband; and Valuska, our hapless hero with his head in the clouds, who is the tender center of the book, the only pure and noble soul to be found. Compact, powerful and intense, The Melancholy of Resistance, as its enormously gifted translator George Szirtes puts it, "is a slow lava flow of narrative, a vast black river of type." And yet, miraculously, the novel, in the words of The Guardian, "lifts the reader along in lunar leaps and bounds."

Join us as we get together to see Paul Rudd in the latest comedy-drama-musical from John Carney, POWER BALLAD! The film follows a washed-up wedding singer, a fading boy band singer and a stolen hit song. Here’s a description, trailer and plan for this event: DESCRIPTION: Rick, a washed-up wedding singer, and Danny, a fading boy band star, bond over music and a late-night jam session. When Danny turns Rick's song into a hit, Rick sets out to reclaim the recognition he believes he deserves. Power Ballad is written/directed by John Carney, the master of the modern musical and creative mind behind Once, Begin Again and Sing Street! It stars Paul Rudd, Nick Jonas, Peter McDonald, Marcella Plunkett, Havana Rose Liu and Jack Reynor. BUZZ & ACCLAIM: The film premiered to rave reviews at this year’s Dublin International Film Festival where critics call it “a sure-fired crowd-pleaser” that “just might be the feel-good hit of the year!” Others say, “Paul Rudd delivers a career-best performance in this charmer” that’s both “hilarious and deeply moving!” SUMMER OF ICE CREAM, VOL 2: SHAKE NO. 8!

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. 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. 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 created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
