Pay the **5 € board gaming fee** to the bar at the counter when you arrive. You must be at least 18 years old to enter [Arkade](https://www.arkade.fi/). We play in English and the game rules are taught before starting play, unless everyone is already familiar with the game. No previous experience with board gaming required. Despite our RSVP numbers here on Meetup, we almost always have at least 20 people participating weekly. The venue has a great board game library, the host and other players usually bring their own games too: our selection varies weekly. We're a very casual group so you're welcome to arrive early or late and join whatever game is starting up, there is no attendance tracking, or welcoming process. The bar has alcoholic drinks, mocktails, and soft drinks available as well as some snack foods. They've been okay with people ordering food to the bar with meal delivery services. If you are feeling sick, please stay home.

Laid back get together to network and exchange over a couple of drinks.

What does it mean to *know* something? We often say things like “I know this is true,” but philosophy asks a deeper question: what separates knowledge from mere belief? If someone believes something that happens to be true, is that already knowledge — or is something more required? In this meetup we will explore some of the central questions of **epistemology**, the philosophical study of knowledge: * What is the difference between **belief**, **truth**, and **knowledge**? * Do we need **justification** in order to know something? * Can we ever be certain about anything? * Could we be radically mistaken about the world — dreaming, deceived, or living in a perfect illusion? * Is it possible that **knowledge itself might be impossible**? Philosophical skepticism raises the unsettling possibility that we might never truly know anything at all. If all our beliefs could in principle be mistaken, what would count as genuine knowledge? We may also briefly discuss famous philosophical puzzles, such as the **Gettier problem**, which challenges the traditional definition of knowledge as *justified true belief*. No prior knowledge of philosophy is required. The goal is not to reach final answers but to explore the problem together through open discussion. Bring your curiosity — and perhaps a few things you think you know. **Description by ChatGPT**

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! When? ⏰ Usually Tuesday to Friday from 15:00 - 16:00 Where? 📍 In a cozy Viennese coffee house: The Good Coffee Company, Eerikinkatu 33, Helsinki The Good Coffee Company A Taste of Vienna 🇦🇹 Eerikinkatu 33, 00180 Helsinki Please visit our Facebook page for updates and changes: https://www.facebook.com/TheGoodCoffeeCompany/events

Let's play Mafia together! Locations: Oodi library, Group room #4 (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

**14:00 to 15:30 - Beginners Uke Session** We will take you from zero to playing your first song in around 30 mins, and by the end of our session you will have enough of the basics to join in with our jam session. We have spare ukuleles if you don’t have one of your own. **15:30 to 17:30 - Jam Session Part 1** As more experienced players turn up, we will play a range of songs which everyone can join in with. This is when the sing-a-long / play-a-long really starts. The second part of this session often has a theme around an artists, genre or season. Each song has an instrumental section, and we encourage people to improvise, harmonise or just to play it as they feel it. **17:30 to 18:00 - Food Break** Grab something from the menu, chat to your fellow players, meet new people. Look through the song book. Start playing random stuff. **18:00 to 20:00 - Jam Session Part 2** We will play some more advanced songs. The last part of the session is requests from the jam group. Come and join us for a play-a-long jam. We will be based in the cellar bar at Iguana on Mannerheimintie. We keep it simple ... we put the words and chords on laptop. Please bring a tablet if you have one so you can also access the songbook at ukejam.online ... or you can use one of our TV screens we will have dotted around the place. We will have a limited number of spare ukuleles and guitars. If you don't play anything, you are welcome to come and just hangout, sing if you want to. If you like, pick up a ukulele, and someone will help you play a few simple chords and play along. If you have your own instrument, it is best to bring it. Also if you have a tablet, you can access the songbook at ukejam.online and then you don't have to stare at the TV screen all night. Everyone is welcome ... we also have a community WhatsApp group that you can join when you come to the event. We aim to be a safe and inclusive space for everyone. Beginners and experienced musicians are equally welcome.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
