**[Eng] (Ezt követően magyar nyelven)** Welcome to the MoHu (Monthly Hungarian Professionals Meetup)! This group is for Hungarian professionals living in London/UK who are interested in networking, socialising, and sharing their culture. We aim to organise drinks and other events monthly for Hungarian professionals to connect. We also accept new-gen Hungarians, i.e. those Hungarians who grew up outside of Hungary or those who come from broader ethnic backgrounds who grew up in Hungary or share Hungarian heritage. We aim to create an inclusive Hungarian community in London/UK. **★Join our WhatsApp Group** We will accept only those who are part of this Meetup group. [https://chat.whatsapp.com/CkZsvF99nT3LwRaSVNXPJx](https://chat.whatsapp.com/CkZsvF99nT3LwRaSVNXPJx) **★Criteria for joining MoHu** You need to meet at least one of the following requirements: * You are a Hungarian professional living in or visiting London or the UK * You are a professional with some type of Hungarian background (You can be mixed-race or ethnically non-Hungarian but share the Hungarian heritage. For example, you are ethnically not Hungarian but speak Hungarian because you grew up in Hungary. Another example is you were raised by (a) Hungarian parent(s) outside of Hungary.) \*If you are unsure if you meet any of these criteria, please contact us to check. **★Common language** * We encourage everyone to speak in Hungarian during an event. However, aiming to be a more inclusive Hungarian group, we expect all members to accept English as well (considering new-gen Hungarians). **★What to expect on the day of the picnic** * Bring your drinks, food and snacks as you like (if you can bring your blanket, everyone will appreciate it too!) * Location: [https://maps.app.goo.gl/axPK89pEm9evuPP9A](https://maps.app.goo.gl/axPK89pEm9evuPP9A) * **If it rains, we will meet at a pub instead (please keep an eye on our messages on the Whatsapp Group):** [https://chat.whatsapp.com/CkZsvF99nT3LwRaSVNXPJx](https://chat.whatsapp.com/CkZsvF99nT3LwRaSVNXPJx) **[Hun]** Üdvözlünk a MoHu-n (Monthly Hungarian Professionals Meetup)!

**What this is** A lot of women have said they want a space where they can actually meet and communicate properly, so this is a simple BSL social. It’s a group of women meeting at the bar, practising British Sign Language, chatting properly, and spending a couple of hours together. Most women come on their own. That’s completely normal here and we make sure you don’t feel it. Women usually range from their 20s through to their 60s. It’s normally a mix of new and returning women, so you won’t be the only new person there. If you’re feeling nervous, that’s very common. You can message beforehand or on the day and we can help you settle in. [www.thelcommunity.com/bsl-club/](https://thelcommunity.com/bsl-club/) **Where to find us** BFI Bar London **What to expect** Some women already know some BSL, others are completely new. The setup makes it easy to actually practise and communicate rather than just sit and watch. You can go at your own pace and join in as much or as little as you want. **Important** This is a female-only lesbian space. That boundary is clear and upheld at events. **How to attend** You must register in advance to attend [www.thelcommunity.com/events](https://www.thelcommunity.com/events) One quick note on how the community works L Community is member-funded. The standard contribution is £13 per month and covers the platform, events, moderation, and safeguarding. If £13 isn’t workable right now, you can opt out. Most people just come to a few things first and decide later. Support can be changed or cancelled at any time [www.thelcommunity.com/back-us-now](https://www.thelcommunity.com/back-us-now) **Arriving and support** If you’re nervous or can’t find us, Message and we can come and meet you WhatsApp Jenny +44 7591 386019 **Staying connected** To access WhatsApp groups and stay part of the network: [www.thelcommunity.com/go](https://www.thelcommunity.com/go)

On this photo walk, we're taking a completely different approach to West London, skipping the usual tourist bottlenecks at Notting Hill Gate. We’ll explore the transition from picturesque, tranquil canal to gritty urban spots, through to vibrant local market. Beginners and experienced photographers are all welcome. * **Little Venice:** We start along the scenic canal towpath by the colourful narrowboats, boat owners and canal life before heading toward Meanwhile Gardens where the scene shifts and the traditional urban street photography scenes open up. * **Golborne Road:** The heart of the local Moroccan and Portuguese communities. With a quieter flea market and community vibe, the area offers great opportunities for candid street portraits and urban scenes, overlooked by the iconic brutalist style Trellick Tower. * **Portobello Road:** We’ll walk the length of the market in reverse. Entering from the northern end lets us catch the local characters first, before following the street's natural transition into the Notting Hill Gate traditional starting point which is where we'll end things. Please note that this is not a teaching workshop event. However, if you have any street photography questions or need advice during the walk please feel free ask me. As an extra bonus I've created a Street Photography Cheat-Sheet available for free download for members. Optional. We will end the photo walk at a pub or cafe for a quick drink for those who wish to regroup socially post walk. **What to Bring** * **Camera Kit:** Any camera or smartphone. No tripods required. * **Travel Light:** Comfortable shoes and clothing suited to the weather. \*\*\* **Event Info** * **Duration:** 2 hours * **Meeting Location:** Little Venice, London * **Limited Spaces:** 10 \*\*\* **PAYMENT OPTIONS** * RSVP via Meetup (standard fee applies) * Or send £7.50 via PayPal to \*\*[street@lindawisdomphotography.com**](http://street@lindawisdomphotography.com%2A%2A/) — no extra fee * Message me to confirm your spot & I will add you to attendee list. \*\*\* **Bonus for Members** * **FREE DOWNLOAD –** Street Photography Cheat-Sheet * **FACEBOOK COMMUNITY GROUP:** A private FB group is available for group members to share their favourite event photos and receive feedback if requested.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. 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.
