Let’s take a little Sunday escape from the city and enjoy some fresh mountain air together. If the weather cooperates, we’ll organise a relaxed **open-air meetup on Sljeme**, combining coffee, a cable-car ride, a gentle walk through the forest, and lunch at a mountain lodge. This is a **very easy hike**, suitable for almost everyone, the walk is mostly flat with only a few small uphill or downhill sections. *** ## ☕ Step 1 – Coffee Meetup We start the day with a relaxed coffee gathering: 📍 **[Dr. Who Café](https://www.instagram.com/explore/locations/2087441298235509/caffe-bar-drwho/)** 🕚 **11:00 – 12:00** If you prefer to skip coffee, you can simply join us at the cable car. *** ## 🚡 Step 2 – Cable Car Ride 📍 **[Sljeme Cable Car](https://www.zicarasljeme.hr/) Base Station** 🕧 **12:30** From there we’ll take the cable car up the mountain and **exit at the Brestovac station** (the penultimate stop). *** ## 🥾 Step 3 – Easy Walk From Brestovac we’ll walk **less than one hour** to the mountain lodge **Runolist**. The path is scenic and mostly flat, making it perfect for conversation and enjoying nature. *** ## 🍲 Step 4 – Lunch at Runolist Lodge [Runolist](https://runolistsljeme.com/) has a small cantina where we can have lunch together. Typical meals cost roughly **10–20€**. After lunch we’ll walk back the same way and return to the city. Expected arrival back in Zagreb: **around 17:00 (5pm)**. *** ## 💳 Cable Car Tickets 🚡 **Free** for Zagreb residents with an ID showing Zagreb domicile 🚡 About **10€ return** for others *** ## 🌦️ Weather Note This meetup is **weather dependent**. If the weather turns bad, we will simply keep the **coffee meetup at Dr. Who** and skip the mountain trip. Please **check the [WhatsApp group](https://sites.google.com/view/smallfridayinternationalzagreb/faq/sfiz-whatsapp-guide-keeping-it-fun-and-respectful) on Sunday morning** for the final confirmation. *** ## 🌿 What to Expect • relaxed pace • friendly international crowd • fresh air and forest views • casual conversations • optional lunch together No hiking experience required, just good shoes and a good mood. ***

## (Lesson 2) ## What to expect Project Equilibrium is an in-person introduction to disciplined, rule-based trading automation. This first event is designed to be clear, practical, and approachable no hype, no pressure, and no prior technical background required. ### Why we meet (two-session structure) This meetup is structured as **two lessons**: **Lesson 1 — The “Why” (mindset + framework)** * What Project Equilibrium is (and what it is not) * Why we focus on process, rules, and execution discipline * What “24/7 execution” means in practice * Q&A and open discussion **Lesson 2 — The “How” (step-by-step setup)** * A simple walkthrough of the basic tools you need * Step-by-step guidance to install and prepare the required exchange apps/accounts * A clear checklist to be ready for future sessions (You won’t be left alone—everything is explained calmly and in order.) ### What to bring To make the second lesson smooth, please bring: * **A smartphone** (for authentication and exchange app setup) * **A laptop** (for the setup steps and configuration) If you only have one device, you can still join Lesson 1. The setup lesson is simply easier with both. ### Who this is for * People curious about algorithmic execution and portfolio discipline * Beginners who want a structured approach * Experienced traders who want more consistency and less stress ### Agenda * Welcome + introductions * Lesson focus of the day (Why / How) * Guided walkthrough (where applicable) * Q&A + next steps ### How to find the group * Arrive a few minutes early and look for the **Project Equilibrium** group. * I will be there to welcome attendees if you’re unsure, simply ask the venue staff for the Meetup group name.

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.

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.
