Decentralized Systems & Applications

Join the **Ljubljana Embedded Meetup** on **March 26** at **18:00** at **Visionect (Tržaška cesta 118, Ljubljana, 3rd floor)**, where **Bojan Musizza** will introduce Renode and show how system emulation can accelerate embedded development. Embedded development is often constrained by hardware availability and challenging debugging. In this talk, we will introduce Renode, an open-source framework for emulating embedded systems, and show how it can help accelerate development and testing. Using practical examples, we will demonstrate how Renode supported the development of a driver for the timing controller of an e-paper display and helped investigate hard-to-reproduce bugs. We will also show how it could be used to provide an emulated target for a software team developing a JavaScript application that runs on the device. The talk will include a short live demonstration and highlight how system emulation can make embedded development faster, more flexible, and easier to debug. The meetup is open to the public and will be held in Slovene language. The lecture will be followed by a group discussion and socializing with snacks and drinks.

It’s a great chance to hear how others are handling the transition and what’s actually working for them. * **When:** Tuesday, March 24th @ 18:00 * **Where: Celtra Offices (Kongresni trg, Ljubljana)** ### **Agenda** * **18:00:** Drinks and arrival * **18:15:** Lightning Talks with Q&A * **Jure Gorinšek** (Outfit7) * **Boštjan Špetič** (Teads, Računalniški muzej, super!

**Kako lahko plačam parkirnino v Ljubljani z bitcoinom????** Ta mesec bomo imeli v **Torek**, **24.3.2026 ob 19h v kavarni Sputnik** srečanje s **Petrom Opara** srečanje kjer nam bo predstavil kako lahko v Ljubljani plačamo parkirnino z bitcoinom. Na tem srečanju bo Peter predstavil **Lightning Parking** — hobi projekt, ki ti omogoča plačilo parkirnine v Ljubljani z uporabo Bitcoina. Vneseš registrsko tablico, parkirno cono in število ur, skeniraš Lightning račun z katerokoli LN denarnico in ko je plačilo potrjeno, se samodejno pošlje SMS za aktivacijo tvojega parkirnega mesta. Brez aplikacije, brez računa, brez fiat denarja — samo satsi. Projekt je bil zgrajen s pomočjo AI agenta, Peter pa bo govoril tako o tehnični plati (Lightning računi, prejemniki plačil, SMS integracija) kot o tem, kako v praksi izgleda razvoj s pomočjo AI agenta. *** **Predavanje je namenjeno vsem, ne glede na predznanje. Ni vstopnine, vendar se prosimo prijavite, saj je število mest omejeno!** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ***Prav tako pa bomo imeli člani Bitcoin društva Slovenije pred meetupom ob 18uri tudi redni letni občni zbor. Zato vse, ki še niste poravnali članarine prosimo, da to storite do nedelje 22.3.2026 in se nam v torek pridružite. Na občnem zboru bomo pregledali kaj vse smo delali v letu 2025 in kakšni so plani za leto 2026.*** Za vse, ki pa še niste člani pa vas vabimo da se nam pridružite na [https://bitcoin.si/clanstvo/](https://bitcoin.si/clanstvo/).

Yes you can!!!** This month we will have a meetup on **Tuesday, March 24th, 2026 at 7 PM** at Café Sputnik with **Peter Opara**, who will introduce us how we can pay parking in Ljubljana using bitcoin. At this meetup, Peter will present Lightning Parking — a weekend project that lets you pay for parking in Ljubljana using Bitcoin's Lightning Network. Enter your licence plate, parking zone, and number of hours, scan a Lightning invoice with any wallet, and once the payment settles, an SMS is automatically sent to the city's parking authority to activate your spot. No app, no account, no fiat — just sats. The project was built with the help of an AI coding agent, and Peter will talk about both the technical side (Lightning invoices, payment listeners, SMS integration) and what the experience of building with an AI agent actually looks like in practice.The talk is intended for everyone, regardless of prior knowledge. There is no entry fee, but please register as seating is limited! See you on **Tuesday**, **24.3.2026, at 7:00 PM** at Kavarna Sputnik. The meetup will last approximately 1 hour, followed by a social gathering in the café.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
