Bring your management challenges; whether you're managing people, products, processes or beyond, and solve them together with peers from a diverse set of backgrounds. This event is great for anybody trying to create better ways of working and wants to share with + learn from others trying to do the same.

You want to make animated short film, collaborate on, or be part of the creation process; this meetup is for you! From animators, storytellers, character designers, 3D modellers, sound designers or voice actors, join in and share your work. We present our creations and work processes, share our knowledge and skills, give and receive honest constructive feedback.

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

Drake Lundstrom is presenting: Code Anywhere by Talking to your Phone Abstract: Have you heard the trend of people deploying code anywhere from checkout lines to doctors' offices? In this talk, you will learn how to talk to your phone and have an app on Azure to show your friend 5 minutes later. The basic DevOps tools you already know, plus a little bit of AI magic, are all you need! If you want to follow along, the demo will be in Azure with GitHub Actions and GitHub Copilot, and you can have it set up on your phone by the end of the session. Just come in with an Azure account and a GitHub repo. Join us for pizza, drinks, and networking @ Improving's office. Doors open at 5:45.

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

Join other experienced and aspiring agile coaches and professionals to: * develop and practice your coaching skills in a peer-to-peer environment * share current successes and challenges in your work environment and get support from each other * learn from each other, build better relationships and experiment with new ideas

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.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
