OWASP

Join us on **Easter Monday, 6 April**, for a **Parks on the Air (POTA)** outing from **Ticknock** in the Dublin Mountains. If you have not come across POTA before, it is all about bringing amateur radio into the great outdoors, setting up in a qualifying park, and making contacts from the field. We did a quieter test run on Bull Island recently and it went well, so this time we are opening it up to the wider **TOG community and the public**. We will meet at **10:30am** at the **Ticknock café** and then head off to find a good place to set up and operate. We expect to be on air for around **two hours**. You are very welcome to come along, help out, and even have a go on the radio using the **club callsign EI0TOG**. Jeffrey Roe, **EI7IRB**, will be leading the activation. Jeffrey is planning to cycle out, but there is parking nearby too. If radio is not really your thing, or you do not want to stay for the whole activation, Ticknock has plenty of walks so you can still join us for part of the outing. After the POTA activation, there are also IRTS 2m and 70cm contests running, so anyone who wants to keep the radio fun going is welcome to do that too. As always, this one is weather dependent. If the conditions are awful, we will give it a miss rather than spend another Monday getting soaked. Read the full details here: https://www.tog.ie/2026/04/pota-on-easter-monday-from-ticknock/ We hope to see some of you there in person, or hear from you on the bands.

TOG Watch Night: The Secret Life of Components (Tim Hunkin) We’re kicking off a new bi-weekly Monday Watch Night at TOG. We’ll watch an episode of Tim Hunkin’s “The Secret Life of Components” together, then have a relaxed Q&A and discussion afterwards. This is a friendly, low-pressure way to learn the kind of practical tips you normally only pick up through years of making, fixing, and building. Perfect for beginners, makers, repair folks, and engineers who enjoy the practical side of components and mechanisms. How it works \- Watch together \(one episode per night\) \- Q&A and chat after: questions\, examples\, tangents\, and “how would we do this at TOG?” \- If you miss a week\, no stress\. Watch it at home and come along to the next one First session \- Monday 26 January \- Episode 1: Chain \- Free and open to all \- TOG Hackerspace \(Dublin 12\, D12 CF6V\) Full details: https://www.tog.ie/2026/01/tog-watch-night-the-secret-life-of-components-tim-hunkin/

Join me for a swim on Monday 6th April at 1pm, Weather pending. All are welcome - newcomers and established members, swimmers, paddlers, and toe dippers. I recommend that you don't stay in too long, like me, this time of year, and stay within your dept. We look out for each other but we are not lifeguards. Bring warm clothes for after the swim as it's a bit cold this time of year. Meet in shelters in front of tower near sea Look forward to seeing you all there.

Drop in to our regular Open Social for a great alternative Saturday evening. It's a great informal way to see the space and meet members and visitors. If you’ve never been in before, we’ll give you the grand tour of the space. Talk to members and visitors about projects or things that you’d like to do. If you like what you see, ask about joining as a full member. Membership brings many benefits. Weather and volunteer permitting, we might have our wood fired pizza oven going outside! [https://youtu.be/TTQ0YylkEzc](https://youtu.be/TTQ0YylkEzc) Expect caint, ceol agus craic as usual. The space stays open until the last member is left……usually the small hours of Sunday morning. You can drop in for 10 minutes, or stay the whole night. We have lots of free parking available. Bring beer, food, gadgets!

Lots of people are probably using skills written by the community, but you can make significant improvements to the speed of your own Python development by writing your custom skills. **Author:** Ciarán Tobin [https://www.linkedin.com/in/ciar%C3%A1n-tobin-6b609650/] [I'm the CTO and Founder of EdgeTier, an Irish company that builds software for contact centres.] ============================= **Talk: Exploring Wordle in python** A talk about solving Wordle in Python: taking a few guesses and finding the words that match. I'll start out with Unix pipes, then refine my approach several times in Python, fixing subtle problems and showing a few tricks. Audience: intermediate to expert.

TOG will be open on Tuesday evenings from 19:00 to 21:30 for a general Open House event. Expect to find members and visitors in the space up to all sorts of activities. It's a great time to drop in and see what the space is about. If you're an artist, tinkerer, maker or just plain curious, come in and see what the space is about. Maybe you already have something to work on (or want to), have something to fix, create, design, bodge or tinker... drop in. We're also open for just for plain old social chat and hang out, with plenty of tea, coffee and biscuits. We have lots of free parking right outside our door.

Got something broken at home that you have been meaning to sort out for a while? Bring it along to our next Repair Café at TOG Hackerspace on **Saturday 11 April 2026**, from **12 noon to 4pm**. The event takes place at **TOG Hackerspace, Unit 1B Motor City, Kylemore Road, Dublin 12**, and tickets are free. A Repair Café is a chance to bring along broken or worn items and sit down with volunteer fixers to see what can be done. It is not a drop-off service. You stay with your item, chat through the issue, and get to see what is involved in trying to bring it back to life. Sometimes the repair is quick, sometimes it takes a bit of testing and head-scratching, and sometimes the item has other ideas, but you will usually come away knowing a bit more than when you arrived. You can bring things like: * Clothes and accessories * Toys * Small electrical appliances and electronics * Small furniture There is always a good mix on the day, and while we cannot promise miracles, we do enjoy a challenge. Repairing things keeps useful items in use for longer, saves money, reduces waste, and helps people build practical skills. It is also a nice social afternoon: cups of tea, odd screws on tables, and the occasional cheer when something suddenly starts working again. This event is supported by **Dublin Maker**. Please book your free ticket in advance here: [https://www.eventbrite.ie/e/repair-cafe-tickets-1980452469649](https://www.eventbrite.ie/e/repair-cafe-tickets-1980452469649) If you would like to be a fixer or volunteer at a future Repair Café, we would love to hear from you too.

😅 **Știu că nu ar mai trebui să ... dar încă fac asta!** 🤦‍♂️ **Știu că ar trebui să... dar cumva tot nu fac ce trebuie.** 😬 **Vreau să fiu mai îndrăzneț... dar îmi pun singur piedici.** 🧠 **Este oare într-adevăr posibil să preiau controlul asupra minții mele subconștiente?** Gândește-te la câte oportunități ai ratat sau de câte ori ți-ai pus singur piedici, toate din cauza acelui sentiment ciudat din interiorul tău. Unii numesc asta frică, alții spun că este vocea interioară sau doar un vibe ciudat. 🌫️ Acel sentiment vine chiar din mintea ta subconștientă, iar ea nu este tocmai specializată în decizii logice și bine gândite.🤔 ### 🌌 **PUTEREA MINȚII SUBCONȘTIENTE** Pe parcursul prezentării „Puterea Minții Subconștiente” vei primi explicații clare și practice despre: * Ce este mintea subconștientă cu exactitate * Cum creează ea sentimente sâcâitoare, nedorite * De ce unii oameni se simt mai stresați ca alții * Ce încearcă de fapt să facă subconștientul cu TINE * Aceasta nu este doar o altă prelegere în care stai și asculți. 🎤 Este interactivă și vie, așa încât poți întreba orice, oricând. 💬 În sfârșit vom aborda cea mai importantă întrebare dintre toate: ✨ **Cum poți tu recâștiga controlul asupra minții tale subconștiente?** ✨ Rezervă-ți locul acum! 🗓️ **21 APRILIE 2026 - 7PM** 📍 *Church of Scientology & Community Centre of Dublin* Firhouse Road, Dublin D24 CX39

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

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!
