Ruby

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.

Most language exchanges are built around **movement**. —fast rotations, brief chats, surface-level conversation. New table. New person. Start again. It feels productive. It isn’t. Real conversations don’t happen in 10 minutes. They start there. Then they get interesting. At Flip Lingoes, **you stay.** Same table. Same group. Enough time for real conversation and real connection, beyond the surface level. Every 5 minutes, you switch roles: **fluent speaker ↔ learner**, not people. Before you arrive, **[create a profile here](https://www.fliplingoes.com/language-exchange-dublin/)**[,](https://www.fliplingoes.com/language-exchange-dublin/) tell us what language you're learning. This helps our **automated matching algorithm** put you in the right small group. No awkward searching. No guesswork. Simply scan the QR code on arrival and it automatically matches you with fluent speakers of your target language. We host events at Zanzibar Locke: calm, well-designed, easy to hear, easy to focus. *** **Event Flow** 6:45–7:15 → Seamless check-in (QR code, get matched, sit down) 7:15–8:30 → Language Exchange (structured, focused) 8:30 → Optional social + snacks included **Crispy chicken wings. Cheesy loaded nachos.** Straight from Zanzibar Locke’s kitchen. Perfect for chatting, relaxing, and refueling after a great language session. **Entry:** €8 (tasty snacks included) **Bundles:** 4 events €24 \| 10 events €50\, purchase [here](https://www.fliplingoes.com/language-exchange-dublin/?pricing_filter=in_person#bundles-section) in advance for express check in. Save time and money. **Be generous and invite a friend for free:** It's simple. Create a profile [here](https://www.fliplingoes.com/language-exchange-dublin/), log in, and click “**Invite Friend** to sign up.” It generates a link and you send that to them. Easy and your friend will thank you later ;) If they register for the event before you, you both get free entry.🙌 \*P.S We ask if you consider to buy a drink at the bar upon arrival and support their venue and excellent hospitality in the heart of Dublin. *** **Why Flip Lingoes works:** * Go deeper: longer conversations at the same table * Speak with the right people via automated matching * Smooth, calm, focused environment * Fun social finish If you’re tired of restarting conversations and want to **actually speak beyond the greeting and small talk**, this is your place. [Flip Lingoes](https://www.fliplingoes.com) is a new and innovative language exchange event, with a clear vision: **To upgrade language exchange events online and in cities around the world.** Currently in Dublin, Zurich and Online. **Can you guess our next city?** **Flip into our world:** **[On Instagram](https://www.instagram.com/fliplingoes/)** **[Sign up to FlipLingoes.Com](https://www.fliplingoes.com/language-exchange-dublin/)** ***

## 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 😊

We really hope to see you there!

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! 🎯

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.

Join us to **practise and improve your target language with native speakers on Thursday downstairs in River Bar** (Burgh Quay, Dublin 2) from **6.30pm to 8.30pm**. **Our system:** **• You sit opposite a native speaker of the language you're learning** **• You speak 5mins English, 5mins other language, then change table** This ensures everyone gets an equal opportunity to practise the language they're learning. Our team seats people, controls the time, organises the table changes etc. What to expect: • Relaxed easy going atmosphere • Professional and quality service • Great networking opportunities • All levels welcome from absolute beginner to fully fluent • A big mix of ages with attendees at each event from 18 to 70+ years old • Topic cards on the tables to help start conversations Wide range of languages: We usually have **native speakers of English, Spanish, French, Portuguese, German, Italian, Japanese, Chinese** and more depending on who shows up. **Admission fee €7** (€6 for student card holders). **No pre-registration required, just show up**.

No need to move venue this time! *** Want to support the group? 🙏 Running this thing costs over €200 a year, yep, all out of pocket for now 😅 If you’d like to chip in, we’d really appreciate it, click on one of the links: **[PayPal](https://paypal.me/meetuppay)** **[Revolut](https://revolut.me/michelf9a)** — you can pay with your card, no need to be on Revolut!

📚 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! 😊

Dear fellow Gaeilgeoiri, Cead mile failte / a warm welcome to this group of Irish language lovers and enthusiasts. Hope you will enjoy everything it has to offer and feel free to suggest new events, and, why not step in as an event organizer? What this group is not: - A group limited to those with perfect proficiency in the language, where any single word of English is banned, and where you will get corrected for every séimhiú that, God forbid, you might be forgetting What this group is: - A forum of Gaeilge enthusiasts willing to share their interest and love of the language. We all started learning a language, including our own, from scratch at some point in our lives. Absolute beginners are welcome and should not feel intimidated. Near perfect and native Irish speakers are also welcome to share their vast knowledge of the language. Hopefully this will create a thriving community of lovers of the language at any level. Beir bua Alex (organizer)
