Smart Contracts

Join Rust Dublin and guest speaker Brian Pane, June 3rd, for two insightful talks 🎟️🎟️ [OFFICIAL BOOKING PAGE ON TI.TO](https://ti.to/dublin-rust-user-group/261-brian-pane) 🎟️🎟️ **TALK 1. Testing Unsafe Rust** Unsafe Rust code is sometimes necessary for performance or functionality reasons. But without the compile-time safety net of the borrow checker, extra care is needed to get the code right. This talk shares some useful testing tools and techniques to help evaluate the correctness of unsafe Rust. **TALK 2. Mechanical Sympathy in Rust Performance Optimization** Modern computers are fast, but nuances of their design and implementation can have profound impacts on program speed. This talk, based on the author's work contributing performance improvements to the Rust compression library zlib-rs, describes how a closer look at the hardware’s strengths and weaknesses can help make fast software even faster. **ABOUT BRIAN** Brian Pane spent his career leading the development of networking and infrastructure software at companies including Roblox, Pinterest, Dropbox, and Facebook. After retiring, he now focuses on open source Rust software.

This Meetup was created as a sacred place for those who feel called to explore consciousness, spirituality, personal growth, and the deeper aspects of who we are. We come together every two weeks not for casual socializing, but to connect with depth, presence, and authenticity. Everyone’s perspective is welcome here without judgement. My intention for this gathering is to be conscious and deliberate—like a living container that supports us all in being seen, heard, and understood. This space may not be for everyone—and that’s okay. If you’re looking for light social banter or casual networking, this group may not resonate with you. But if you feel called to walk into a space where people speak from the heart, share with honesty, and lean into spiritual exploration with wonder and sovereignty—then you’re in the right place. We don’t always know where the conversation will flow—but we trust the current. And every time, it brings us to understanding each other from a deeper level. If this resonates then I look forward to sharing this space with you. ***All are welcome and facilities are wheelchair friendly

Our midweek training session :-) Choose from 5km, 7.5km or 10km

## Details The title of the event is a paradox! Read in silence and then discuss with like-minded folks! :-) 📝 **How does this work?** We will meet in the Bartley's Restaurant area from 7:00 PM to 8:15 PM for silent reading and followed up by discussion. **During silent reading, you're expected to remain silent and read.** Please bring your headphones and refrain from the discussion during the first one hour in the area. 👥 **Socialising** After an hour, at 8:15 PM, we'll discuss and socialize about the book you're reading. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! Feel free to join at any point during the event. The event is indoors, hopefully, we can continue the tradition of the silent reading in the winter! **📌 Helpful Tips and Notes** * Bring headphones to block out surrounding noise * I will post a comment on the event page when I arrive to indicate where we're seated, so everyone can find us * If you prefer to skip the silent reading, you can join directly at the bar at 8:15 PM ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. It may be small but don't hesitate to reach out to me. Looking forward to meeting you all 😊

OpenClaw is having a moment. A personal AI agent that runs on your own machine, talks to you and actually gets things done. **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** It runs on your own machine - a Mac Mini, a Raspberry Pi, a VPS - and actually does things: runs commands, browses the web, manages files, talks to your apps. You reach it through WhatsApp, Telegram, or whatever chat app you already use. It works in the background, remembers context between sessions, and connects to whatever AI model you prefer. No engineering background required. If you can install an app and follow a guide, you can do this. We're running this as part of a three-event OpenClaw series this June, with this being the first. The following events build on the setup and focus on getting productive with the agent and applying it to real work use cases. **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** We'll be working through it together at Baseline, tables of people at different stages, helping each other along. Fresh install or halfway there, there's a spot for you. The goal is simple: leave with OpenClaw alive. Connected to WhatsApp or Telegram. With a personality you've written. Doing at least one real thing. What we'll work through together: * Getting OpenClaw set up (locally or hosted) * Connect to a messaging app: WhatsApp or Telegram * Picking the best model for the job * Writing a SOUL.md: giving your agent a personality that's actually yours * Setting up a MEMORY.md layer * Connecting one real skill before the day is out **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** Prep materials will be sent in advance. Come ready, or come from zero. Both are fine. Bring a laptop. That's it. Run of show: 11:00 Doors open, coffee 11:30 Intro and setup overview 12:00 Build time 13:00 Lunch 13:45 Back to building 15:30 Share what you've got running 16:00 Close **NOTE: Registration needs to be completed here: [giveago.co/register/openclaw-1](https://giveago.co/register/openclaw-1)** \-\-\- ​**Community** [Give(a)Go](https://giveago.co/?utm_source=luma) is a Dublin-based builder community running hands-on events for ambitious people who make things. 30+ events. 1,000+ attendees. Partners include PostHog, LangChain, ElevenLabs, HubSpot and Windsurf. One rule: learning by building.

Hi 🙋‍♂️ we will meet at 7pm at ‘the Sails’ sculpture. We will walk along the seafront prom to the wooden bridge and back & stop for a drink & chat in the Yacht pub. To get to the walk start from town:- Clontarf dart station is just a short walk away. Or there are lots of bus stops close by too. Look forward to seeing you on the walk!! 😃 ***Note: if you are delayed or need to cancel, can you please leave a message below so that we can wait for you (or cancel your booking) thanks 🙏

Search is one of those things that *feels* simple — until you're the one building it. Why does `$regex` fall apart at scale? How do you handle typos, relevance, and performance all at once? And what happens when users search by *meaning*, not just keywords? Join the **Dublin MongoDB User Group** for an evening dedicated entirely to **Search** — from the foundations of Apache Lucene, to building production-grade search experiences with MongoDB Atlas Search, to the frontier of Semantic Search with vector embeddings. We'll also have a real-world use case walkthrough from someone who's been in the trenches solving search problems for customers. And yes, you can walk away with an 🎖️ **Search Fundamentals Skill Badge** 🎖️ which you can share on your LinkedIn profile. No laptop needed, just your phone! *** **🛠️ What we're covering:** **The "Why" — Search is Hard** A practical look at why developers struggle with search: fuzzy matching, relevance scoring, tokenisation, and why regex just doesn't cut it. **The "Story" — A Real Use Case** Hear from a practitioner who's helped customers go from "this search is broken" to "this actually works." Less Lucene textbook, more honest problem-solving. **The "How" — Atlas Search Deep Dive** We'll go under the hood on how Atlas Search (built on Apache Lucene) works, and show you how to wire it up in your own applications. **The "Future" — Semantic Search** Beyond keywords — how vector embeddings and semantic search let your application understand what users *mean*, not just what they *type*. *** **📅 Agenda (6:00 PM – 09:00 PM)** * **6:00 – 7:00 PM \| Networking & Pizza 🍕** * **7:00 – 7:30 PM \| Search 101: How Search Actually Works** From text indexing to Lucene — the fundamentals every developer should know. * **7:30 – 8:00 PM \| Real\-World Search Use Cases** What does bad search look like? What does great search look like? Stories from the field. * **8:00 – 8:30 PM \| From Generic Search to Atlas Search & Semantic Search** How MongoDB Atlas Search brings it all together — and where vector embeddings take you next. * **8:30 – 09:00 PM \| Search Fundamentals Skill Badge 🎖️ \| Open Discussion & Networking** *** See you there! 🎯

📚 Pride Month is a chance to come together around stories that feel lived-in, complicated, and real, and this discussion invites us to sit with those voices rather than just skim them. Its roots go back to the Stonewall Riots, and since then Pride literature has grown into a bold, varied body of work—from Giovanni’s Room to A single man and Normal People, each capturing different shades of love and identity. As we read, the aim isn’t just analysis but conversation—what resonates, what challenges us, and what these stories say about how people find themselves and each other. Let's grab a drink (alcoholic or non-alcoholic) and discuss books on pride —whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###
