A list of Seed7 advantages. A hello-world Seed7 example program. The advantages of Seed7 are discussed in detail: This includes **compile-time execution**, **integer overflow checks**, the **absence of pointers and NULL**, the static type system, ahead of time compilation, types as first-class citizens, abstract data types, **templates**, **parser as part of the run-time library**, the Extended Backus-Naur Form, **Seed7 Structured Syntax Definition**, defining the semantic of a for-loop, how languages evolve and the **Seed7 test suite**. **Talk 2nd:** **Claude Code - How AI Agents Are Changing the Way We Code** Claude Code is Anthropic's agentic coding CLI that lives in your terminal. it autonomously reads your codebase, edits files, runs tests, and ships PRs — all through natural conversation. I'll give a live demo covering its latest features: * **Sub-agents**: parallel, specialized AI workers with independent context windows * **MCP** (Model Context Protocol): connecting Claude to external tools like Firecrawl for live web search/scraping, databases, Slack, and more — right from the terminal * **Hooks & Skills**: custom automation triggers and reusable slash commands that personalize your workflow * **Plan mode**: aligning on implementation strategy before the AI writes a single line of code * **Auto-memory (CLAUDE.md)**: how the agent learns your project conventions and remembers them across sessions * **Voice mode**: talking to your codebase Whether you use VS Code, JetBrains, or just a terminal — this is the future of developer tooling. Live demo included. **About Thomas Mertes \|** 1978 Learned programming in school 1980 Studied computer science at the Technical University of Vienna 1984 Graduated as Diplom Ingenieur Thesis: Design of an extensible programming language 1986 Graduated as PhD Thesis: Definition of an extensible programming language 1988 – 2025 Work as professional software developer in different companies.

**\*\*\* Enrollment and all info** [https://www.iicv.at/intermediate-classes](https://www.iicv.at/intermediate-classes)**\*\*\*** **Description:** **Come join for a journey of some of the nitty-gritty of improv performance.** We’ll work on scene work, stage presence, breaking out of our patterns, finding fun in the stillness, and stillness in the craziness of Improv. This is for improvisers who understand the foundations and concepts of improv and want that extra challenge to perform or refine their performance skills. **Teacher:** Shawn Fisher Shawn Fisher is an improviser, performer, and educator. With over 15 years of experience in improv, you can see him with The English Lovers, one of Vienna’s longest-standing improv groups, Two-Buttons Short, and with Rainbow’s Last Wish. Originally from the US, he has taught classes, workshops and led open improv sessions in Vienna since 2018, fostering community where curiosity leads the way. ​ Whether directing, MCing, or coaching at venues like Vienna’s Maestro, Shawn thrives on the spontaneity and connection of live performance—especially when leaning into the fantastical.

Things to know before playing: Ladies and Gentlemen, boys and girls; We play Thursday Night Football (outdoor only) . We play 90 minutes (kick off is at 20:30, and we meet at least 15 minutes before for a warm up phase). Post-Corona football matches are most likely between 14-16 and 28-32 players. If you would like to join please bring artificial turf shoes (like the ones for indoor turf) and shin pads (not mandatory but definitely recommendable). All I ask is that you come with a good mood, be respectful to everyone, and pay online using the link below. [FOOTxp Thursday Night Football](https://footballexperiences.net/kickaball/p/thursdaynightfootball/) Other methods for payments. **Bank Transfer**: Sorin-Florian Brici AT27 2011 1829 5564 7001 **\* [Revolut](https://revolut.me/brici)** \- Recommended **\* [Wise](https://wise.com/pay/me/sorinb256)** \- Also recommended **\* [Paypal](https://www.paypal.com/paypalme/sorinSocial)** \- Please use non\-Commercial product We play light: no sliding, hard tackling, fighting, screaming, & hopefully no injuries. We need to respect current regulations in Vienna, Austria. The main priorities are to have fun and being safe. The drinks are relatively free after the game in the local pub, served to those who have shown fantastic football fair-play skills. We’ll confirm the location, the pitches, and the dressing room numbers via our dedicated Football WhatsApp group. Keep an eye out for the group messages. See you all soon. Sorin SMS/ WhatsApp +43 6764276984 (please ask to be added to our football groups). We will probably need to confirm your presence if you are coming for the first or second time. Important management rule: \> "No shows" are penalized with 10€ fee\. Please remove your name from the list at least SIX\!\!\! \(6\) HOURS before the event\. Book a place via FootballExperiences\.NET using this link [Kick A Ball via FOOTxp.COM](https://footballexperiences.net/kickaball/) One small final note: Please avoid trying to take justice in your hands. If someone is talking bad, complaining, insulting someone, fouling on purpose or committing the usual football shenanigans, please let the organizers know. Measures will be taken, we assure you. Any misbehavior on your part, such as responding in an obscene way, fighting, or leaving the pitch is not a practical and diplomatic way of resolving the issues (it tends to create more tension and cause more problems). Let’s be respectful and mature and try to enjoy the game we all love. That’s why we’re all here. Get to know people from all over the world and have fun! Thank you. Sorin

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.
