Learning Finnish in Finland can be difficult because Finns tend to switch to English. That is one of the reasons people like our Finnish language café: you get to practice Finnish with Finns :) The events are completely free and there is always a native speaker to facilitate the conversation and to help find the right words. The coffee is good too ☕😋🇦🇹 Tervetuloa!

East Helsinki should be an independent country. Where people stand for things. Empathy, compassion, gratitude and everything good and left.

Tervetuloa mukaan Sahaja Jooga -meditaatiotilaisuuksiin suomeksi! Tilaisuudet ovat maksuttomia, ja voit tulla paikalle ilman ennakkoilmoittautumista. Istumme yleensä tuoleilla tai lattialla tyynyillä, joten mattoa ei tarvitse ottaa mukaan, ja voit pukeutua tavallisiin vaatteisiin. Meditaatio tarkoittaa mielen hiljaisuutta tai ajatuksetonta tietoisuutta. Olet läsnä tässä hetkessä, mutta mielesi ei ole täynnä menneisyyden tai tulevaisuuden ajatuksia. Tässä tilassa tunnet rauhaa ja iloa, jotka ovat nykyhetken olennaisia elementtejä. Säännöllisellä meditaatioharjoituksella tämän tilan voi saada vakiintumaan meissä. Ryhmää johtavat vapaaehtoiset, joilla on kokemusta ja jotka voivat ohjata sinut alkuun. Annamme lyhyen johdatuksen meditaatioon, minkä jälkeen teemme meditaatioharjoituksia. Annamme myös vinkkejä meditaation harjoittamiseen kotona. Tervetuloa! Tämä video auttaa sinua löytämään Kamppi Sahaja Jooga -keskuksen: https://vimeo.com/199566137 Lisätietoa Sahaja Jooga -meditaatiosta: www.discoversahajayoga.org (englanniksi) www.jooga.org (suomeksi) www.sahajayoga.ru (venäjäksi) www.sahajayoga.es (espanjaksi) Ohjattuja verkkomeditaatioita, jotka tukevat meditaatioharjoitustasi kotona: www.wemeditate.com

Let's play Mafia together! Locations: Oodi library, Group room #8 (2nd floor). Mafia is a role playing social deduction game. People sit around the table, and are secretly assigned a role. The role divides them in two teams: \- Mafia \(minority\) \- Citizens \(uninformed majority\)\. Members in the Mafia team know each other, but the citizens don't. You are not allowed to reveal your role in any way. Each turn consists of a night time and day time. During the night: The Mafia team secretly "kills" one member of the Citizens. Players with special roles (detailed below) secretly use their ability. During the day: Everyone presents their opinions on who they think are in the Mafia team, or present arguments as to why they are not in the Mafia team if they have been accused. Vote for those players you think are in the Mafia team - those who get a majority vote (>= 50%) will get a chance to present their defense. Vote to "eliminate" 1 person in the defense - the accused will not be eliminated if there are no votes or gets <50% of the votes. The game continues until either the Citizens eliminate all Mafia members, or the Mafia becomes the majority. ++++++++++++++++++++++++++++++++++++++ Most of the people at our event have experience playing the game. But we are glad to meet new people, and will be happy to briefly introduce you to the game rules and players' strategies if you decide to come. ++++++++++++++++++++++++++++++++++++++ Special roles at our game party: Doctor (Citizen team): At each night, you can save a player who you think the Mafia team has killed. That player cannot be killed by the Mafia team that night, and the Mafia do not know who you saved. You can save yourself once. Detective (Citizen team): At each night, you can point to a player you think is in the Mafia and the narrator will show thumbs up if they are in the Mafia team. You can not detect the Godfather. Sniper/Professional (Citizen team): Each night, you could either choose to kill someone you think is in the Mafia, or not shoot. You have only two bullets. If you select a citizen to shoot, you go out of the game yourself, but that citizen is still in the game. Constantine (Citizen team): During the night, you can bring back one dead person to life. This can be used only once per game. Matador (Mafia team): Each night, you can diffuse someone's special ability. You can not diffuse the same person two nights in a row. Godfather (Mafia team): You're the head of the Mafia. The detective can not detect you. Terrorist (Mafia team): During the day, you can reveal your character, and choose to kill yourself and another player. The latest time you can do this is during when someone (e.g. you) are presenting their defense. The person you kill with yourself cannot be resurrected by Constantine

【IMPORTANT SUMMARY】 * The purpose of social games is to know some people, do some exercise and enjoy the games together with others. Winning and getting points is not the focus of this session.

[https://7538e9.myshopify.com/products/saturday-badminton](https://7538e9.myshopify.com/products/saturday-badminton) * We don't use the signup system on Meetup.com anymore. (Neither the waiting list) * It says this event is full on this meetup page, because I didn't open any slots here for you to sign up. You have to check this [sign-up page](https://7538e9.myshopify.com/products/social-game) to see if there is still a slot available there. * The background of using an external sign-up and payment system is because Meetup.com introduced a service fee to increase 21% of the fee in May 2023, and we want to reduce this cost. 【FEE and REFUND POLICY】 * Fee includes courts and plastic shuttles. Please sign up and pay before you come. NO refund if you do not cancel until 48 hours before the event. * Racket: bring one or rent one at the counter. * You can put a comment to sell your slot after the deadline of refund, or sell your slot in our whatsapp group. * No matter the reason is sickness, accident or anything, the group or I will not afford the cost caused by your absence. * Of course you CAN'T ask me, "Can I sign up for free for next week because I didn't come to use my slot this week?". Please remember, the court booked for you was there and it costs money. The court doesn't simply become "free of charge", just because you didn't come to use it. 【COMMUNICATION】 * Communication: our whatsapp group [https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347](https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347) * There are too many spams, so I only accept +358 number to join whatsapp group.

People will respond. * We play double games to 21 points. After each game, please let those who are waiting to play. Feel free to play with whoever you want, but please avoid playing with the same people all the time. * If you are new to badminton, please Google basic badminton rules in advance. Serve rules, double rules and point counting rules. You are always welcome to ask anyone in our group. Most of our members are more than happy to help you. * Badminton activity is organized for non-profit purpose, but I take a small fee for my work. * Want to restring your racket?

Therefore, **individuals with a refugee background are welcome to attend free of charge without prior registration.** If you plan to join, simply send a message to Alaa to let us know you’re coming.

Our events are designed to support the mental health and well-being of refugees and immigrants, while also encouraging dialogue that challenges cross-cultural stigmas and stereotypes.

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!
