**Co-working for writers in Amager!** Join us for an hour of focused writing time. All writers and all experience levels are welcome and don’t worry, no one will see what you've written. This session is about getting your writing done and meeting other writers in the area. We meet in this lovely spacious café, chilled out, usually not very busy at this time, with an on-site bakery of delicious pastries. Once everyone is here and settled, I will lead a quick introduction, and then set the timer for our quiet and focused writing session. After the hour is up feel free to chat / take off / keep writing if you're on a roll. We often talk about our successes and challenges as writers, and it can be a great way to learn from eachother. **A note about the format** We don’t host critiques or readings. These events are a safe space for writers of all skill levels and genres to work on their craft, so no one will read or critique your writing.

Fulfillment. Joy. – Do you know what it is? Do you feel it now? Many of us are living lives that have “just sort of happened”. We had a dream, a vision (maybe we still do) for what we wanted our lives to look like. Somewhere along the way, life took over and something else ended up happening. We made decisions, took a turn down a path, and now our life isn’t what we thought it would be. Or we’re living someone else’s life. Maybe it’s what our parent’s wanted for us. What we believe our partner or a potential partner might want. Or maybe it’s what we believe we need to do and have to be happy. I was one of these people. My life checked all the boxes for what I thought I needed in order to be happy. And still, I wasn’t. Join me for a coffee talk on what it means to live a Life By Design. Where your choices are deliberate and based on your authentic, true self. What you have to let go off to achieve this (hint: the notion that vulnerability is a weakness and feelings of fear and guilt) and who you will become in the process.

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at our Copenhagen Shut Up & Write! sessions. Be it a book, blog, script, essay, dissertation, résumé, 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: - 15 minutes of hellos and getting settled; maybe some quick intros. - Then, the timer starts! : writing for 1 hour. - After the hour is up... chat / take off / keep writing, if you're on a roll. OPTIONAL SOCIALIZING happens once the hour of writing is complete. Writing can be very solitary... connecting (and sometimes even commiserating) with other writers is a cool thing. It's best to be on time, but BEING LATE IS ALSO OKAY: just show up and get settled, then check in with us after the session. (We’ll be the ones with the small Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer. 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.

**RUN THE CITY. MEET THE WORLD.** We launched something new - and what a success it was! With up to 40 people we run beautiful routes through Copenhagen on our social runs - and you're invited to be part of the next edition. In the future, we will post and track our runs on CYKOM (platform/app), as we thereby have the opportunity to get connected with brands to elevate our runs and maybe provide us with some drinks or similar occasionally. To establish this well it would be great if you can take a minute and join our running community there and also join the next run via the following link: https://app.cykom.com/LJUg/o7izxl02 **DEAR WORLD RUNS** is for those who want to move, connect, and feel the city in motion. Whether you're a regular runner or just curious to join, this is your moment. 🏃‍♂️ **The Run** • Friendly but fun pace around 6:15 min/km to be able to chat but with ambition • Approx. 5–6 km, accessible for most • You don’t need to be “fast” - just bring energy ☕ **The Vibe** • Post-run coffee/tea included & hangout at Nomad Day Bar in the 25hours hotel on beautiful Paper Island • Come solo or bring a friend - we’ll make it social • Led by the Dear World crew you can leave your belongings that you don’t want to take along the run with the venue which will secure it while we are gone. 📍**Where & When** Nomad Day Bar / 25hours Hotel Paper Island 🗓️ Tuesday every 2 weeks 🕙 18:00H sharp (meet from 17:45) **We run the city - join us.** Let’s make this the start of something that moves us all. #DWRuns #DearWorldCPH

Welcome to another exciting evening of NixOS! If there are no speakers, we just hold a regular hack evening. Room: Kantine, 1. Sal, PASCAL\* ## Details Interested in NixOS? Maybe only its package manager Nix? Want to share how you (ab)use Nix(OS) in your own company? Join this NixOS user group meet-up! Topic will be announced. *Why NixOS?* **NixOS The Purely Functional Linux Distribution** NixOS is a Linux distribution with a unique approach to package and configuration management. Built on top of the Nix package manager ( nixos.org/nix ), it is completely declarative, makes upgrading systems reliable, and has many other advantages ( nixos.org/nixos/about.html ). **Declarative** NixOS has a completely declarative approach to configuration management: you write a specification of the desired configuration of your system in NixOS’s modular language, and NixOS takes care of making it happen. **Reliable** NixOS has atomic upgrades and rollbacks. It’s always safe to try an upgrade or configuration change: if things go wrong, you can always roll back to the previous configuration. Come join us for a cosy night of Nix(OS). There will be pizza, kindly sponsored by PROSA

**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?** Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎 Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic. The goal is to help develop our Critical Thinking, Communication, and Community 🙌 **📓 HOW DOES IT WORK?** Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX), along with jump-off points to get the conversation going. When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture. **General Meeting Agenda** Each Practical Philosophy meet-up follows this general timeline: * 19:00-19:15 - People arrive and chat, get to know each other before the ‘official' start. * 19:15-19:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines. * 19:25-20:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them. * 20:45-21:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo. * 21:00 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other. **🧧PRICING?** Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though! **💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY** 🗣 “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam 🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel **🤓 FAQ** * ​What will we talk about? What's the topic? ​The topic for the week is shared every Sunday in the Whatsapp group. We try to add the topic to the comment section on this event page as well but if you don’t see it, the topic and the jump-off points will be in our [Whatsapp](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX). * Do I need to study or read anything to attend? No preparation is necessary. This isn’t a study of other thinkers. We want to know what YOU think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it, but it's not required. * Is there a specific philosophy that Practical Philosophy is focused on? The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school. * Is it mostly men that attend? Surprisingly, no! Although philosophy is seen as a Candelabra affair in a dark room with a bunch of guys, our Practical Philosophy meetups are generally 50/50 between genders, and we don’t meet in any dark rooms. * Can I come alone? Of course you can, we encourage it :) * Can I be late? Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation. * Where do you meet? The location is posted in Meetup and our [Whatsapp](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX) group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website](https://www.practicalphilosophy.club/practical-philosophy-locations/). 🤝**POLICY** To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment. **PRACTICAL PHILOSOPHY - Making Philosophy Available To All. ✨** Practical Philosophy hosts weekly, in-person meetups in 25+ countries, including Canada, Spain, Japan, Mexico and many more! 🗺️ \*\*\* Join our [Whatsapp group](https://chat.whatsapp.com/CRqdyO6p6lZDIN2qVRIlWX) 👈 Follow us on [Instagram](https://www.instagram.com/practicalphilosophyclub/?hl=en) 👈 Our [website](https://www.practicalphilosophy.club/) 👈

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

What does a trojan look like when it has over 900k+ combined installs and a Forbes write-up? Exactly like a legitimate Chrome extension. This session presents a technical dissection of two Chrome extensions, each with over one million active installations — that functioned as trojans in production environments, evading detection while operating through entirely legitimate browser APIs. These were not obscure tools. They were widely trusted, actively recommended, and covered by mainstream press before their malicious behavior was fully understood. We will walk through the actual source code of both extensions, showing precisely how the malicious functionality was constructed, concealed, and executed at scale. This analysis anchors a broader examination of how modern compromises actually succeed. Drawing on aggregated real-world incident data, we identify the technique categories currently delivering the highest adversary return, and why they keep working. Spoiler: it's rarely a zero-day. It's trust. The Chrome extension deep-dive will cover: * Line-by-line source analysis of how malicious functionality was embedded within working, useful software * Which browser permission scopes were abused, and why a million users — and their IT teams — didn't see it coming * The behavioral and structural indicators that distinguish a trojan extension from a legitimate one, and how to operationalize detection around them This session closes with a practical defensive prioritization framework built around observed attacker behavior: which mitigations are measurably reducing risk in production environments, which are consuming budget without impact, and a scoring methodology your team and leadership can apply immediately. **Source material:** Primary analysis of extension source code, corroborated by reporting from Forbes and other established outlets. **What this is not:** A vendor pitch, a speculative threat narrative, or a surface-level breach retrospective. **Who should attend:** Security architects, AppSec and cloud security practitioners, blue team leads, threat hunters, browser security practitioners, and security leaders responsible for prioritizing risk and investment decisions.
