Sessions of **individual runic readings** are available for beginners all along summer, both online (75 CHF) and offline in Zurich (100 CHF). These sessions are **NOT** esoteric or divinatory. We're approaching runes as **a symbolic system of archetypes** to examine any situation or question that is currently relevant to you. *If you feel stuck in a situation and cannot see a way forward, are facing a difficult decision, navigating a period of uncertainty, or trying to understand a recurring pattern in your life, a runic reading may offer a different perspective.* **You will receive:** • a clearer and systemic understanding of what is actually happening; • insight into hidden influences affecting the situation; • a better understanding of why certain difficulties keep repeating; • greater clarity around available options and their likely consequences; • practical ideas for what to do next.

**About** Join us this evening to learn about discovering and interacting with the hidden world of (radio) signals. Our speakers will show you how to detect, capture, analyse, manipulate and transmit radio frequency signals for fun as well as in professional settings. **Agenda** 1. 15’: Welcome note (Urs/Reto and SCS) 2. 30’: Introduction of SDR and how to use it to build a mobile phone direction finder. The presentation is about a proof of concept that showed the feasibility of using OpenBTS to locate missing persons using SDR. Presentation in German. (Christian Bach) 3. 40’: Implementation of a GNU Radio based SDR sniffer for the Wi-SUN protocol and integration with Wireshark. The [gr-wisun](https://github.com/husqvarnagroup/gr-wisun) project is used as an example for how a practical implementation for a complex protocol is possible with GNU Radio (and why it’s relatively straightforward). Presentation in English. (Andreas Müller) Presentations start at 19:00. Afterwards we’ll have plenty of time to discuss and socialize. **About the speakers** * [Christian Bach](https://www.linkedin.com/in/christian-bach-231b34166/) has a Diploma as an Electrical Engineer from the University of Applied Sciences FHNW, specializing in Communication Technologies, and currently works as Project Manager at [Supercomputing Systems AG](https://www.scs.ch/). * [Andreas Müller](https://www.linkedin.com/in/andreas-m%C3%BCller-94b9a2173/) has an MSc in Information Technology and Electrical Engineering from ETH Zurich, and works as embedded team lead at the GARDENA digital hub in Zurich, working on the [GARDENA smart system](https://www.gardena.com/int/c/discover/products/smart-system).

**Speakers:** Paulo Martins (GitLab) – **We Tried to Detect Indirect Prompt Injection in Coding Agents. Here’s What Broke** Gianlorenzo Occhipinti (Exa) – **Beyond the Knowledge Cutoff: Agentic Search in Practice** Marius Colacioiu (Norm) - **Your Repo Is the Memory: Durable Context for AI Coding Agents** **Agenda:** 17:30-17:40 – Welcome & intro 17:40 – 18:10: Paulo Martins 18:15 – 18:45: Gianlorenzo Occhipinti 18:45 – 19:15: Marius Colacioiu **Abstract**: **We Tried to Detect Indirect Prompt Injection in Coding Agents. Here’s What Broke** As a community, we are delegating a significant part of our development workflow to agents, and as the use cases grow, the risk of prompt injection keeps increasing - to the point that it made it to the top of the OWASP LLM Top 10. In this talk, I’ll explore the concept of “detect and prevent prompt injection” and why it is particularly hard to do for coding agents. \-\-\- **Beyond the Knowledge Cutoff: Agentic Search in Practice** An LLM is a lossy compression of the internet: the long tail gets blurred, concepts interfere, and anything after the training cutoff simply doesn't exist. The fix isn't a bigger model, it's giving agents the ability to search. This talk walks through the shift from classic retrieve-then-read RAG to agentic search, where the search engine becomes part of the agent's environment and the model learns what, when, and how to query: decomposing questions, parallelizing searches, and chaining multi-hop lookups \-\-\- **Your Repo Is the Memory: Durable Context for AI Coding Agents** AI coding agents are becoming useful fast, but they still do not know the local truth of your codebase. This talk shows how to make repo-local context durable so agents produce work that fits the project and humans can still understand, review, and maintain what gets merged.

Dies ist ein informelles Treffen für Lernende, die ihre ersten Schritte in der Programmierung machen oder ihre Grundkenntnisse vertiefen möchten. *** This is an informal meetup, for learners that want to do their first steps in programming or want to consolidate their skills. We spend one hour and a half working on tutorials, exercises or projects. If you need help to get started, we will help you finding a good way for learning. You should be prepared to spend your time "doing things": just hanging around and listening might get boring, if all other people are learning on their side. There are experienced people are around and you can ask questions as soon as their arise or bring with you questions you have had during the week. During the last half an hour, we do a (simple) exercise together. We speak German, English, and a few other languages. Currently, how main programming languages are: * Python * Javascript * Java * Flutter * C++ * C * C# * PHP But you're free to learn any programming language during our Co-Learning! If you want to learn more about our Co-Learning, please have a look at our website (no frequent updates...): https://opentechschool-zurich.github.io/ If you're starting with Python, we can suggest: * Learning Python the hard way (https://learnpythonthehardway.org/python3/) (for Python 3). * The Solo Learn Python 3 Tutorial (https://www.sololearn.com/Course/Python/). * A big list of Python tutorials: https://docs.python-guide.org/intro/learning/ For Node.js: * Nodeschool: https://nodeschool.io/ For C++ * https://de.wikibooks.org/wiki/C%2B%2B-Programmierung * https://www.sololearn.com/Course/CPlusPlus/

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.
