Donderdag 21 mei 2026 is het weer tijd voor onze Techday: hét vaste moment waarop we kennis delen, elkaar inspireren en nieuwe ideeën direct in de praktijk brengen. Deze editie pakken we het aan als een conferentie in het klein. Drie sprekers, drie verhalen, één middag – drie verhalen voor de prijs van één. Wat kun je verwachten? **Dirk neemt een kijkje onder de motorkap van AI** AI voelt voor veel mensen als magie. In deze talk probeer ik de magie weg te nemen door een kijkje te nemen onder de motorkap. Een essentieel bouwblok van moderne AI is een neuraal netwerk. Als je begrijpt hoe een neuraal netwerk werkt, is het een stuk makkelijker om te begrijpen hoe en waarom een LLM werkt. De beste manier om iets te begrijpen is door het te bouwen, vanaf scratch. Dus dat gaan we in deze talk doen. Door dat te doen leren we over artificial neurons, activation functions, backpropagation en meer. **George vertelt hoe AI Cyberaanvallen verandert** George Schizas (extern), voormalig IT Manager, nu werkzaam als CISO, vertelt over zijn ervaringen in de Cloud Cyber Security en hoe hackers met behulp van AI nieuwe aanvalsmethoden kunnen gebruiken om kwetsbaarheden op te sporen en te exploiteren. Hij geeft voorbeelden van manieren om in Kubernetes omgevingen in te breken en noemt manieren om dit tegen te gaan. **Roland duikt in de wereld van de fraude fabriek** Als ontwikkelaar kom je dagelijks in contact met technologie en de laatste jaren natuurlijk ook vaak met AI. JIJ snapt heel goed wat de voordelen en de gevaren zijn, maar hoe leg je complexe onderwerpen als AI gegenereerde afbeeldingen, Voice Phishing en Hallucinaties uit aan je ouders, de buurvrouw, of je kinderen? Ik neem jullie mee in een realistische situatie waarin Anna en haar familie opgelicht wordt met behulp van verschillende technieken en hoe dit oplichters-landschap met behulp van AI verandert. **Wanneer:** Donderdag 21 mei 2026 **Wat:** Techday – conferentie-editie “AI kansen en valkuilen” **Voor wie:** Iedereen (!) die nieuwsgierig is en wil leren **Agenda** 14:45 - 15:00 - Inloop 15:00 - 16:00 - Neurale netwerken 16:15 - 17:15 - AI risico’s en kansen 17:15 - 18:00 - Eten 18:00 - 18:45 - Fraude fabriek We zien je graag op de Techday!

Come along, lovely queer hikers! 🌿✨ This time we’re serving an easy-going queer nature moment with a short loop through **Landgoed Heidestein** near Zeist.

(english/german below) **Bitcoin Pizza Dag!** Op 22 mei 2010 betaalde programmeur Laszlo Hanyecz 10.000 BTC voor twee pizza's — de eerste gedocumenteerde aankoop met bitcoin. Hij plaatste een bericht op een forum waarin hij BTC aanbood voor pizza; een andere gebruiker ging akkoord, bestelde de pizza's en leverde ze af. Die transactie werd later bekend als "Bitcoin Pizza Day". Laszlo bewees dat Bitcoin als ruilmiddel gebruikt kan worden. **Sluit je bij ons aan voor pizza-avond bij De Pizzabakkers! (vanaf 18:00)** RSVP zo snel mogelijk; we moeten reserveren bij De Pizzabakkers en er is beperkte plek. Zorg dat je je geladen Lightning-wallet meeneemt! *** **English: Bitcoin Pizza Day!** On May 22, 2010, programmer Laszlo Hanyecz paid 10,000 BTC for two pizzas — the first documented purchase using bitcoin. He posted on a forum offering BTC for pizza; another user accepted, ordering pizzas and delivering them. That trade later became famous as "Bitcoin Pizza Day," Laszlo proved that Bitcoin can be used as a medium of exchange. **Join us for pizza diner at De Pizzabakkers! (from 18:00)** Please RSVP as quick as possible as we need to make a reservation at De Pizzabakkers and there is only limited space. Be sure to bring your loaded lighting wallet along with you! *** **Deutsch: Bitcoin Pizza Tag!** Am 22. Mai 2010 zahlte Programmierer Laszlo Hanyecz 10.000 BTC für zwei Pizzen — der erste dokumentierte Kauf mit Bitcoin. Er postete in einem Forum und bot BTC für Pizza an; ein anderer Nutzer akzeptierte, bestellte die Pizzen und lieferte sie aus. Dieser Tausch wurde später als "Bitcoin Pizza Day" bekannt. Laszlo bewies, dass Bitcoin als Tauschmittel verwendet werden kann. **Begleite uns zum Pizza-Abend bei De Pizzabakkers!

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it.

**Studio 151 Learning Lab: Photography Foundations Series — Lighting Basics** Photography starts with light—but understanding how to actually *use* it is where most people get stuck. This session is designed to simplify lighting in a way that makes sense for real-world shooting. Instead of a traditional lecture, we’ll learn through curated video content, pausing to break things down, ask questions, and connect it to real studio work. You’ll see how lighting works, talk through it as a group, and then have the chance to explore it hands-on. *** **What We’ll Cover** * Natural light vs. studio light (and when to use each) * Simple one-light setups that work * How light direction shapes your image * Creating clean, consistent results *** **What to Expect** * Guided video learning (watch + pause + discuss) * Real-time breakdown of concepts in plain language * Hands-on opportunities to experiment * Open networking with other photographers * Snacks will be available, bring a bagged lunch if you like! *** **You’ll Leave With** * A clearer understanding of how light works * Simple setups you can try immediately * More confidence in any shooting environment *** Free to attend (limited spots)

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St). Turn left onto Station St or Lynn St. * **Driving (via VA-286/Fairfax Co Pkwy):** Take the Elden St West exit. Turn right onto Lynn St. Looking forward to seeing everyone again and getting back to building!

**In a time of division and isolation, come be part of the community that's rebuilding the town square, one table at a time.** In BreadBreakers, we use the common space of the dining table to have conversations where neighbors can **hear, be heard, and know one another.** If you're hungry for good conversation and deeper community, join us for a Community Dinner in Reston and help blaze the trail to a healthier, more connected society and democracy. Here’s how it works: For just two hours, multiple tables of people set aside the need to "win" and instead focus on sharing, listening, and connecting. Guided by experienced table hosts, we'll tell our stories, try to understand each other, and practice being in community with those with different views or backgrounds. **At this dinner, participants will get to choose between three different topics, including some current events.** Topics range from the political, to the "slice of life", to the spiritual, to the philosophical, to the off-the-wall - but no matter which table you choose to sit at, you can be sure it'll be like no dinner conversation you've had before! You can also **suggest a topic** by emailing us at BreadBreakersInfo@gmail.com. Food will be provided for free. For those who wish to provide a donation to help fund BreadBreakers, you can [give here](https://pushpay.com/g/restorationrestonumc?fnd=pO6G-N7oO7FH7Mp1u-x6mA&fndv=Lock&r=No&lang=en&src=pcgl) or at the event. We'll have vegetarian and gluten-free options available. If you have any additional dietary restrictions (Celiac Disease, vegan, etc.) please let us know at BreadBreakersInfo@gmail.com so that we can implement the appropriate food handling procedures. **Join us, invite a friend, and be a part of the movement to mend our fractured society and normalize a better way of talking with one another.** BreadBreakers, an initiative by [Restoration United Methodist Church](https://restorationreston.org/breadbreakers) in Reston, VA, is a religiously inclusive community. We are a collaboration between people of all faiths and stripes. Our leadership, volunteer team, and community include people who attend Restoration and people who don't.

Join us at **Hashtag** in Herndon on Thursday, **May 21st** at **6pm**. Adventure and roll dice with this week's **Starfinder** **GM: Maria**. **The story:** Having secured a secret entrance to the Wreck of the Returned, the Starfinder Society is finally ready to launch a rescue mission into the Wreck, to liberate the lost Starfinder Zizenzi and the countless other citizens of Akiton who’ve been abducted by the Functionary’s forces and await forced conversion into mindless servitors of the Wreck. While numerous teams prepare to enter the conversion facility, First Seeker Sarmak has tasked one special team with breaching the conversion facility’s central control room and dispatching the cure to conversion through the ventilation system. If successful, all the converted innocents within the Wreck will regain their autonomy and break free from the Wreck’s control. Unfortunately, the central control is sure to be heavily guarded… Prepare for battle, Starfinders! **Notes**: Replayable (with a different character) *This is an adventure in the ongoing Invasion's Edge metaplot.* \*\*\*\* **The Characters:** You can use a [level 3 pregen](https://paizo.com/starfinder) *or* bring your own if you have a society character in the 3-4 range.
