Zurihac shirts, or other Haskell events paraphernalia mark the spot! :D You're invited to Haskell Office Hours, a laid-back meetup where you can ask questions, get help setting up the Haskell toolchain, or just hang out with fellow Haskellers. This meetup is geared for newcomers, but experts are also welcome to show up and join in the knowledge-sharing. In this meetup we are going to focus on the [Cesraparsec library](https://github.com/hekazu/cesraparsec) that was the topic of the [Haskell Library Workshop](https://jarkkaa.fi/events/20d7c2a9-5380-4f6b-8508-1d9ced68724b) event. There is also a [page for the event in järkkää.fi](https://jarkkaa.fi/events/ea0a344d-7385-4b81-a2b8-38411d7dabbb). For more coordination, join our [Newcomers Matrix room!](https://matrix.to/#/!wnXpJkwWACgSBBzwDh:matrix.org?via=chreekat.net&via=matrix.org&via=rauhala.info) Happy Haskelling!

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!

Suomenlinna is a UNESCO World Heritage site and a classic summer picnic location only 15 minute ferry ride away from downtown Helsinki. Join us for a tour of the island, and if feeling up for it, check out the various museums located around the island where both the Museum Card and the Helsinki Card grant free entry. There's no pre-planned route or destination — instead we'll take a walk around the fortress ruins and pop in wherever we're feeling up for it. Afterwards we'll settle in a park somewhere nearby for food and drinks. **Possible stops include:** * [Sotamuseo Maneesi (just opened a new exhibition showing WWII era soviet war propaganda)](https://museot.fi/nayttelykalenteri/index.php?nayttely_id=40407) * [Suomenlinna museum (recently opened a new exhibition showing handcrafted Finnish glass)](https://museot.fi/nayttelykalenteri/index.php?nayttely_id=42566) * [Submarine Vesikko (WWII era submarine so we can imagine what it would feel like having a panic attack after being sunk to the bottom of the sea in a tin can)](https://museot.fi/museohaku/index.php?museo_id=21149) * [Ehrensvärd museum (gawk at how a bunch of rich people lived in the 1700s)](https://museot.fi/museohaku/index.php?museo_id=21096) * [Customs museum (crazy things that have been forbidden from being imported and the crazy ways that crazy people tried to get around that prohibition)](https://tulli.fi/tutustu-tulliin/tullimuseo) We'll get together at the Kauppatori ferry terminal before passing over to the island. Once there, I'll share my location via GPS and everyone's free to tag along for the museum tour or simply take a walk around the island and take in the sights.

Our level range from beginner to intermediate. We will put you to play with people with similar level. But if you are the first time to come and I don't know your level, then I will put you to play with less-experienced players to start. * Please purchase your slot through this link [https://7538e9.myshopify.com/](https://7538e9.myshopify.com/) Please also read the instruction inside this link, so that you have an idea how it works. * Please bring feather shuttles to join the games. We only accept specific shuttles. Please read the following. **If you come without bringing feather shuttles with you, I may ask you to go home.** 【SIGN-UP SYSTEM】 * Please sign up and pay through this link. [https://7538e9.myshopify.com/products/competitive-game](https://7538e9.myshopify.com/products/competitive-game) * 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/competitive-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 the work I do to continue this group. 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. * 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 is there and it costs money. The court doesn't simply become "free of charge", just because you didn't show up. 【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. Numbers from other countries will all be rejected. 【DETAILS of COMPETITIVE GAMES】 * This is the list of shuttles we accept: RSL Classic Tourney, Academy Li-Ning Super 1000 Victor Smash It 1, 2, 3 Ling Mei 70, 80, 90 Ling Mei Gold, Black Yonex Aerosansa 30, 20, 10 NCS Pro, MAX * Smash Center also sells feather shuttles (Ling Mei Gold and Black). You can purchase there at your arrival. 【OTHERS】 * Please always keep 1 meter away from those courts where people are playing. Never step into the corners of other courts! If I see you do this, I probably will yell at you! * If you have some questions, you can put your questions in the comments on the event page. People will respond. * 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.

If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
