Speakers of English and Korean unite! Language exchange focused meetup at a pub venue in a very central London location. For a map of the location, see the website of the bar linked in the venue details given here. People at any level of Korean (and English) are welcome at this Meetup. Complete beginners wanting to explore learning Korean also welcome. Participants come from the UK, Korea and many other countries. This will be an opportunity to informally study and practice Korean and/or English, and help others with their Korean and/or English in return.

Ready to get outside? Our Friday morning Nordic Walk in Brockwell Park is back! At this moment we can meet with up to 30 people (of more than two households) to do outdoor exercise and walks. However, i like to keep our exercise groups small, so I have set the maximum participants at 12. For now this walk is for our experienced Nordic Walkers only, who already used to Nordic Walk with us regularly before Covid 19 kept us indoors, and who have their own Nordic Walking poles. As this session is outdoors, we will not ask you to wear a face mask, but we do ask you to keep 2 meters apart. Some of our walkers might be immune compromised or more at risk, so please help us keep everyone safe! Please do not come to the session and stay at home if: - you know you have been in contact - in the last 2 weeks- with someone with symptoms of possible Covid, or if you have been in contact with someone who tested positive. - you have any of the following symptoms: (new) Loss of smell/taste, Persistent cough, Fatigue, Loss of appetite, Skin rash, Hives, Fever, Severe muscle pain, Shortness of breath, Diarrhoea, Delirium, Abdominal pain, Chest pain, Hoarse voice, Eye soreness, Sore or painful throat, Nausea or vomiting, Headache, Dizziness or light headedness We meet by the Blackbird bakery in Herne Hill, between the station and the park. Session Price: £10 per session, £89 for a 10-session card or £70 unlimited sessions per month. Session cards and Pay Monthly can be used in any of our outdoor walks or indoor Zoom classes sessions (except for the Parkinson's sessions). Pay What Works: The price shown above is the “true” value of the session that best reflects the work I put into preparing and leading your session. However, I understand that not everyone can afford to pay full price, and I don’t want that to stop you from joining us. In an effort to find a balance between more financial accessibility and sustainable pricing, I now offer a “Pay What Works” model. This allows for financial flexibility while still valuing and respecting the work and energy I provide in creating and delivering these classes. Then send an email to ailien@fitandhappyoutdoors.com with the heading “INVOICE please”- followed by “FAHO 1” to pay full price as quoted below, “FAHO 2”, for 20% off, or “FAHO 3” for 50% off. Please do tell me if you want to pay for 10 sessions, or if you’d like to pay monthly. I prefer payment by bank transfer, but if that is not possible you could pay in cash. No cheques please, the queues by the banks are just too long. We walk in all safe weather conditions – if a walk is cancelled, we will contact you to let you know. Please check for text messages or Meetup messages before leaving home!

Location: Ark Walworth Academy Shorncliffe Rd, London SE1 5UJ There will be 24 hours cancellation policy. If you can't make it please update your RSVP 24 hours before the session.

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.

We connect you with up to 30 Men or Women tennis partners close to your PLAYING REGION and skill level.

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!

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!
