The monthly gathering of Ireland's game development community, in the back room of The Circular in Rialto. The format is presentations, playtesting and networking: developers show what they have been working on, and anyone can bring a build and get it played and critiqued on the night. The group runs 1GAM, a one-game-a-month jam, and October's theme is 'Shocking' - prototypes made to that theme turn up here first. If you want to present there is a sign-up form in advance. Free, 19:00, with a Discord that keeps the conversation going between meetups. Why go: it is the one regular room in Dublin where unfinished games get played by other developers rather than pitched to publishers. Best for game developers, artists and designers, from hobbyists to studio staff.
Tog's maker evening: supervised access to the laser cutter and 3D printers for whatever you are building, with help on CAD and machine setup.
Tog's electronics evening — soldering, circuit debugging, PCB design and microcontroller work, with the hackerspace's benches and more experienced members on hand.
Day one of IBM's Qiskit Fall Fest at Trinity, hosted by CONNECT, the Science Foundation Ireland research centre for future networks headquartered at TCD. The day runs from 10:00 to 15:30 in the O'Reilly Institute and covers quantum networks specifically rather than quantum computing in general: keynote talks, research discussions, a poster showcase from the groups working on this in Ireland, and the launch of Dennis McNulty's Quantum Wiki. Free to attend and open beyond the university. Why go: quantum networking in Ireland is a small field and most of the people doing it will be in this room for the day, in a format that leaves time to actually talk to them. Best for researchers, physics and CS postgrads, and engineers tracking where quantum communications is heading.
A hands-on hackathon at the UCD Innovation Academy in the O'Brien Centre for Science, run with UCD Careers, on a single brief: how might we prepare UCD graduates for the jobs of the future. Teams form on the night or arrive together, work the challenge, and take ideas as far as a workable proposal in about three hours. Solo entrants are welcome and get placed. Free, drinks and snacks provided, 16:00 on Tuesday 27 October. Registration is restricted to current UCD students. Why go: a real brief, a short clock and mentors from the Innovation Academy, which is a better first hackathon than most open events. Best for UCD students who want to try building something without committing a weekend.
HUSTLE London Liverpool St Entrepreneur Networking Event
with Patrick Palmer (Principal Security Specialist Solutions Architect, AWS) · Tanya Vo (Lightning talk speaker, Fidelity Investments)
The AWS User Group Dublin takes over the Button Factory on Curved Street for an evening of practitioner talks on building and running things on AWS. Patrick Palmer, Principal Security Specialist Solutions Architect at AWS, has the main slot at 18:00: "The Next Heartbleed Is Coming. Are You Ready?" on frontier AI models accelerating vulnerability research, the post-quantum cryptography migration, and why the visibility and automation both demand are better treated as one shared capability than as separate projects. Tanya Vo of Fidelity Investments follows with a ten-minute talk on the AWS community programmes. More speakers to be announced. Free, registration from 17:45, talks run to 19:45. RSVP on Meetup. Why go: a security talk with real technical content from someone who does the work at AWS, in a room of Dublin developers, architects and founders rather than a vendor audience. Best for engineers and technical leads who own production infrastructure.
An interactive VR workshop at UCD exploring the human eye in virtual reality. No prior VR experience required.
Tog Hackerspace's weekly open evening: a tour of the workshop, the tools and the projects in progress, for anyone curious about Dublin's volunteer-run hackerspace.
with John McFarlane (Software engineer, automotive software, undefined)
This month's Dublin C++ User Group talk, at Anseo on Lower Camden Street. John McFarlane speaks on what it takes to write C++ to a reasonable standard of quality: bug-catching tools, contracts and undefined behaviour, safety-critical considerations, Agile practice and workflow, then a walk through experimental projects combining the approaches he has settled on. He is a software engineer working in automotive software, previously in server software and games, and has sat on national and international C++ committees including the NSAI. 19:00, free. City centre, and the group notes there is no free parking. Why go: safety-critical C++ practice is thinly covered in Dublin, and this is a working engineer on tools he actually uses rather than a survey talk. Best for C++ engineers, especially anyone shipping into automotive or other regulated targets.
Ireland's business sustainability leaders gather for the UN Global Compact Network's annual forum.
Free online community training on tracking single page applications, from the Analytics Pioneers Dublin group.
A Royal Irish Academy and ALLEA workshop on what generative AI is doing to research practice, bringing ALLEA's Research Ethics and Integrity Council together with invited experts. Daniel Carey, RIA president, and Maura Hiney MRIA open at 10:00. Professor Jeroen de Ridder of Vrije Universiteit Amsterdam, who chairs the drafting committee for the Dutch Code of Conduct for Scientific Integrity, gives the keynote on the Dutch experience. Short presentations follow on academic freedom, trust in science and the risk of declining research standards, then a panel with de Ridder, Deborah Oughton and Krista Varantola on whether existing codes still hold. Closes at 13:00 with lunch. Why go: this is where the rules for AI-assisted research are being written, not just discussed. Best for researchers, research managers and anyone drafting institutional AI policy.
A GEC Sustainability Cluster session at the Guinness Enterprise Centre, hosted with Techies Go Green, on where a product's carbon footprint actually comes from. Earlier cluster sessions covered national and sector emissions; this one goes down to the product. It covers the common building blocks of a product carbon footprint, how the Greenhouse Gas Protocol frames the measurement, and worked examples from cut flowers, bottled water and spirits, fast fashion and transport, including where intuition gets it wrong. The last section is on using footprint data commercially, for sourcing and packaging decisions and for answering customer questions before they are asked. Q&A, tea and coffee after. 10:00. Why go: specific and numerate where most sustainability sessions are neither. Best for founders, ops and sustainability leads at any business that makes, imports or sells a physical product.
with Dr Victoria McGovern (Senior Business Researcher, UCD Business School and I-Form)
UCD MechSoc and I-Form, the Research Ireland Centre for Advanced Manufacturing, host a 50-minute guest talk on how Irish manufacturers are actually adopting AI: what is already running in production, where it stalls, and how it is reshaping engineering roles and skills. Dr Victoria McGovern, Senior Business Researcher at UCD Business School and I-Form, presents findings from her research with Irish manufacturing companies, including the problems they have hit. Free, 11:00 to 11:50, room L0.18-LEA in the O'Connor Centre for Learning on UCD's Belfield campus. Pizza afterwards. Why go: a short, free, research-backed read on AI adoption on Irish factory floors instead of vendor slideware. Best for engineers, operations people and anyone tracking where industrial AI is genuinely landing.
with Isabella Sparks (Speaker, Threatcraft) · Aaron Ott (Speaker, )
Dublin's infosec meetup, in the Abbey Room of the Camden Court Hotel, with two talks and a bar. Isabella Sparks opens at 19:00 on Threatcraft. At 19:40 Aaron Ott presents work on an Auto Mode RCE in Claude Code, building on Johann Rehberger's research: a coding agent refuses to run an attacker's decoder, writes its own Python decoder instead, and executes it from inside the directory it just unzipped - where a planted struct.py shadows the real module. He walks the chain from injected prompt to execution and shows how often it fired across runs. From 18:30, free, food and drinks. Why go: agent security is being discussed everywhere and demonstrated almost nowhere. This is a working exploit, explained by the person who reproduced it. Best for security engineers, red teamers and anyone shipping coding agents.
The Dublin chapter of AI Tinkerers runs a demo night with PostHog as marquee sponsor and Baseline as venue partner. The format is builders showing working software rather than slides: short technical demos of what people have actually shipped, followed by questions and open networking. Previous Dublin editions have been run with Notion, Kiro, Exa and Fin, which gives a sense of the standard. Attendance is approval-gated - you apply through the AI Tinkerers site and the exact address is shared with approved attendees. 18:30 on Wednesday 28 October. Why go: it is the most consistently technical AI room in Dublin, and the approval gate keeps it builders rather than spectators. Best for engineers shipping LLM products and founders who want their demo stress-tested by people who have shipped one.
An evening on WordPress's new AI layer at tcube coworking on O'Connell Street, and the first Dublin WordPress meetup in some time. The talk covers the Abilities API, AI Client, Connectors and MCP: how WordPress now talks to AI models and agents, with worked examples of what developers can build on top. Attendees include people from CommerceGurus and from Google's Site Kit plugin, so the room is agencies and plugin developers, though the organisers are explicit that newcomers are welcome too. Questions at the end, open discussion afterwards, and the organisers are collecting suggestions for the next session. 19:00, free. Why go: WordPress shipping an MCP surface changes what anyone building on it can automate, and this is the only Dublin room discussing it. Best for WordPress developers and agencies deciding what to build against the new APIs.
Dublin business networking at IMI Sandyford. Meet SME owners, build real connections, and unlock new opportunities.
TU Dublin's monthly coffee morning for aspiring founders at the Greenway Hub on the Grangegorman campus, 10:00 to 12:00 on the last Thursday of the month. Each edition has a guest founder who talks through their own route from idea to launch and then runs a short workshop on refining your concept and your pitch. An open-mic slot lets anyone pitch and take feedback in a low-pressure room. October's guest is Sean Kirwan, CEO and co-founder of MedWrite.ai, who spent twenty years in digital roles in pharma before founding it. Free. The October edition is full and running a waiting list, so watch for cancellations. You do not need an idea prepared; the organiser asks you to bring a problem or challenge you would like to work on, and the session is built around creative problem-solving. Pitch slots are allocated in advance. There is no parking on site. Why go: one of the few Dublin rooms aimed at people who have an idea and nothing else yet, with a founder who will actually look at it. Best for first-time founders and students thinking about starting something.
Ireland's leading B2B marketplace event, Biz Expo, is coming to the Talbot Hotel Stillorgan in Dublin on Oct 29th 2026.
with Kevin Collins (Host, DCU:Innovate Catalyst)
A four-hour build night that follows a September talk where people who use Claude Code all day sat with people uneasy about AI and worked through three questions: what AI means for their jobs, what it is doing to their families and communities, and who sets the rules. The problems named that evening become the briefs, posted on the event page ahead of the day. Teams of up to five pick a brief and build against it with Claude Code until demos start around 20:00. Judging is on whether the build works live and whether someone could pick it up afterwards. Pizza mid-build. Every participant gets 100 dollars in Claude API credits; each member of the winning team gets a month of Claude Max 20x. Hosted by Kevin Collins of DCU:Innovate Catalyst. Free, approval required, exact address sent to approved registrants. Why go: a rare Dublin room where the brief comes from people outside tech and the build has to answer them in four hours. For developers already fluent in Claude Code, not for learning it.
OutGeekWomen's rescheduled Dublin evening — short talks and open networking for women working in technology across the city. Venue is confirmed to registrants closer to the date.
Tog's locksport session: physical security, how locks actually fail, and supervised practice on the hackerspace's own collection.
Grow Remote's local brunch meetup for remote and hybrid workers in Lusk.
Dr Aleksi Aaltonen of the Stevens Institute of Technology on 'Making Sense of Data in the Age of AI: Data Studies in Management'. His argument: data have always been central to large-scale organising and are becoming more so in an AI-driven economy, but what actually feeds contemporary AI systems resists the simple definitions companies work with, which is why managing, using and sharing data for AI proves so hard in practice. He makes the case for treating data as a research object in its own right, drawing on his own work and the Research Handbook on Digital Data. Part of UCD College of Business's MIS seminar series and its Conversations on AI and Humans collection. 2pm to 3.30pm in Room Q115, Lochlann Quinn School of Business, Belfield. Free. Why go: an academic seminar rather than an industry talk, which is the point - the data-strategy problem framed by someone with no product to sell. Best for data leads, researchers and anyone writing their company's data strategy.
Tog's deliberately AI-free hack night — bring a project, work on it alongside other people, and talk to someone about it. Open to non-members.
