For years, managing UI state on the web meant reaching for JavaScript. But in 2026, CSS has quietly become a state machine of its own. Pseudo-classes track interaction. Media queries read environment and user preferences. :has() observes the DOM tree. Container queries respond to size, style, scroll position, and even anchor placement. Scroll-driven and scroll-triggered animations react to where the user is on the page. And with sibling-index(), CSS can now respond to what's happening next door.

In this atypical "overview" talk, you'll get a practical tour of the CSS features that let you keep and respond to state — from things you can ship today to the cutting-edge stuff landing in browsers right now. Welcome CSS, to the state machine.

Web performance is no longer a luxury—it’s a business imperative: Faster pages boost revenue, improve conversion rates, lift SEO rankings, enhance accessibility and even benefit everyday user productivity.

But the truth is that performance is a continuous discipline, not a one‑off project: Rather than chasing an impossible perfect score, the most valuable gains come from tiny, measurable tweaks that users notice instantly.

In this session we walk through a live, real‑world case study that shows how a handful of practical adjustments can deliver a noticeable speed boost without months of up-front refactoring. You’ll learn:

• Which performance pitfalls surface most often in production code
• How to read and interpret real user metrics that matter
• A toolbox of quick‑win techniques that can be applied today
• When a short‑term fix is appropriate versus when a deeper architectural review is required

By the end, you’ll have a clear roadmap for diagnosing performance bottlenecks, prioritizing the highest‑impact changes and implementing them in a sustainable, incremental fashion—so your own site can start delivering faster, smoother experiences right away.

Running software is a black box. Observability is how you shine a light inside. This talk covers OpenTelemetry from instrumentation to the Collector, showing how to build visibility that helps developers and ops teams alike.

Deine Konkurrenz publiziert schon mit AI. Du nicht. Ich zeig dir die neue Tastatur: Open Source, sofort einsetzbar, gebaut für Content Marketing das funktioniert. Gefunden werden von Google, von Chat GPT, Perplexity von allem, was noch kommt. Starke Slides und 3 Open-Source-Systeme in der Live Demo auf der Bühne: N8N Pipeline, die automatisch ein Blog Magazin auf BloggerIo published. Das NCA AI CMS das Markdown generiert und als statische AstroJS Site ausspielt. LLM Chats die via MCP direkt ins CMS schreiben – aus Claude, ChatGPT oder Gemini. Alles komplett auf GitHub. Das hier ist kein Make-Everything-Ok-Button. Das sind Nächte mit Red Bull und böser Musik. Prompts, die mit TDD und Real Tests automatisch erstellt werden. Vibe Coding im Best Practice Auto Mode. Die ständige Hoffnung und Sucht nach “You are absolutely right i will fix this”. Aber: Jede Iteration macht es besser. Jeder Fix bringt dich weiter. Und am Ende ersetzt die künstliche dich nicht – sie macht dich schneller, präziser, gefährlicher. Der Job als Developer stirbt nicht, er wird nur…mächtiger.
