Become a Landlord/lady. Werde Vermieter/in.
We make landladies and landlords. They buy a flat and pay just 1/4. 3/4 come from tax cuts and tenants. It's not a trick. It's government policy. All German Federal Governments, past and present, of whichever party, want taxpayers to become landlords and -ladies, buy property, rent it out to tenants and enjoy passive income later.
Come here and find out. No strings attached. No sales. Just a meet and greet for orientation.

Das ist Politik: Alle Bundesregierungen wollen, dass Steuerzahler Vermieter werden, Wohnungen kaufen, Mieter reinnehmen und später Beton‑Rente bekommen. Info-Abend nur zur Orientierung. Kucken kostet nichts.

**Referent:** Martin Boßlet, Berater, Dozent und Softwareentwickler
**Datum und Uhrzeit:** Donnerstag, 30.04.2026, 18:00 – ca. 19:30 Uhr
**Ort:** Online mit Zoom
Seit zwei Jahren reden alle über KI-gestützte Entwicklung - und vieles klingt gleich: Gestern war Prompt Engineering der Beruf der Zukunft, heute ist es Context Engineering. Claude Code gegen Codex, GitHub Copilot vs. Cursor, Tool-Vergleiche hier und da. Die Älteren unter uns werden sich mit einem Schmunzeln an Vim vs. Emacs erinnert fühlen. Während CEOs bis hin zum Digitalminister den Untergang der programmierenden Zunft ausrufen, wenden sich viele Entwickelnde frustriert ab. "Das ist nichts für mich" - diesen Satz hört man oft. Die Branche scheint sich in zwei Lager zu spalten: auf der einen Seite diejenigen, die KI fast schon aus Trotz konsequent ablehnen, auf der anderen KI-Propheten, die zumindest der Erzählung nach ihren kompletten Alltag mit KI bestreiten und der Konkurrenz schon längst meilenweit voraus sind.
Die eigentliche Frage lautet: Warum gehen die Erfahrungen so weit auseinander? Die These dieses Vortrags: Der Engpass liegt meist weder im Modell noch im nächsten "Tool du jour", sondern in fehlendem, verstreutem oder nur implizit vorhandenem Kontext. Der Schlüssel zu erfolgreicher KI-Zusammenarbeit liegt deshalb nicht in besseren Tools oder clevereren Prompts, sondern in der ältesten Technologie der Menschheit - Sprache. Genauer gesagt: in Markdown als universeller Schnittstelle zwischen Mensch und Maschine.
Anhand von Architecture Decision Records (ADRs), Mermaid-Diagrammen, **[AGENTS.md](https://www.linkedin.com/safety/go/?url=http%3A%2F%2FAGENTS%2Emd&urlhash=jh-H&mt=F7bnie71WnYrGR3aD-BiSMeaQCiWniKDxaG65SbBgq37lq5u7OZ1P6NjRp-YTlrvhyBy30Lf47AWfYCmtVLwNg99MBUc-2e8qYUzQLXNViKKD4LeW5gizS3yWw&isSdui=true)**-Datei und Agenten-Skills zeige ich, warum Text-First Development kein Retro-Trick ist, sondern ein praktikables Arbeitsmodell für die KI-Ära. Wer Architektur, Entscheidungen und Konventionen in Text statt in Tickets, Chat-Verläufen oder auch nur an der Kaffeemaschine festhält, bekommt bessere KI-Ergebnisse, mehr Präzision und weniger Nacharbeit. Und ganz nebenbei entsteht endlich wieder etwas, das in der Softwareentwicklung jahrzehntelang zu teuer war: aktuelle, brauchbare Dokumentation für Mensch und Maschine.
Kein Talk über Prompt-Hacks, Tool-Vergleiche oder das Tool der Woche, sondern über eine einfache, praktische Frage: Wie müssen wir Software bauen, damit KI-Unterstützung nicht nur beeindruckend wirkt, sondern dauerhaft nützt? Die Antwort ist überraschend einfach: kein Tool-Zirkus, kein Hokuspokus. Einfach nur Text.

Berlin Ethereum Meetup
We're thrilled to welcome you to the Berlin Ethereum Meetups!
Join us as we explore technical and non-technical topics and new ideas, collaborate on projects, and connect and grow our community! Our meetups are open to all - from those new to Ethereum to long-standing community members and developers.
🗓️ **Agenda** *(subject to change)*
🕕 6:30 - 6:45 pm - Arrivals
🕡 6:45 - 7:00 pm - Ecosystem & Community Updates by Eniko (Ethereum Foundation)
🕡 7:00 - 7:20 pm - Building a Truly Trustless Ethereum Wallet for Android by Dirk Jäckel (independent developer)
*Every Ethereum wallet you've ever used secretly trusts a server, and they all silently query centralized RPC providers. This talk presents a different approach: an Android wallet library that eliminates the RPC dependency entirely.*
🕖 7:20 pm - 9:00 pm - Open discussions and community networking
👩💻 Full Node is also excited to offer free coworking for all event attendees on the day of the meetup, starting from 9:00am. Feel free to come by Glogauer Str. 6 early and get some work done!
Berlin is one of the most vibrant hubs for Ethereum builders, researchers, and advocates of privacy, decentralization, and open-source technology. Whether you’re here to learn, contribute, or simply connect, join us as we continue building the next chapter of Ethereum in Berlin.
The talks will be recorded and uploaded to our [Youtube channel](https://www.youtube.com/@ethereumberlin). Subscribe to stay up to date!
Apply to speak at our future meetups: [Speaker Application](https://forms.gle/5y9Y5ywZC7pSEqpV9)!
The event is sponsored by [Gnosis](https://www.gnosis.io/).

Creative Code Stammtisch
**⭐ DOORS OPEN AT 19:30. PLEASE ARRIVE BEFORE 8PM! ⭐**
The Creative Code Stammtisch is a casual show-and-tell for artists, makers, designers, coders, performers, learners and anyone interested in the use of computing skills for artistic expression.
The event is free and open to all, regardless of age, origin, gender or experience. Beginners and first-timers should feel especially welcome! You don't have to be a coder yourself 😃
HOW TO FIND US?
Find Prachtsaal Studio by crossing the courtyard next to Cafe Augusta on Jonasstr. 22, 12053 Berlin.
WHAT SHOULD I EXPECT?
We start with quick introductions, then open the floor to anyone who wants to present something. There are usually around six 10-minute slots available, plus time for questions from the audience. First-timers are encouraged to share their work.
Topics range from net art to computational design and interactive installations all the way to wearable electronics or generative poetry. If you’re wondering whether your own project might fit, take a look at the [Stammtisch archive](https://creativecodeberlin.github.io/Stammtisch/) to see what others have shared in the past.
This event is *not* just for coders! New-media artists and anyone working with technology in their art are very welcome to share. If you enjoy art and/or technology, you’ll likely have a great time, and maybe even learn something new!
BEGINNERS WELCOME!
If you’re new to creative coding, you can find beginner-friendly resources at [creativecode.berlin/learn](https://creativecode.berlin/learn).
THIS IS YOUR SPACE
We do our best to create a welcoming environment for all people regardless of race, ethnicity, color, religion, gender identity, sexual orientation, national origin, age, disability, or genetics. People from group generally underrepresented in open-source, art, and technology fields are warmly encouraged to come by. And if you know someone who might enjoy this meetup but isn’t sure it’s for them, let them know they’ll be welcome!

DJ Workshop
### **DNA. Presents "DJ WORKSHOP"**
### **Curious about DJing and ready to try it Yourself?**
This beginner-friendly workshop is Your first real step behind the decks. In 90 minutes, DNA. Member CZECH STRINGS — a multi-genre DJ with 10+ years of experience — walks You through everything You need to know to make Your first mix. No prior knowledge of DJing, music theory, or equipment is required. Zero.
#### **What the workshop covers:**
The session starts with the essentials: what a DJ actually does, what their role is, and how it all comes together. From there, CZECH STRINGS explains the gear using the decks available at the spot as a live example, applicable to any DJ setup You might encounter in the future.
#### **You will learn the core technical skills needed for Your first transition:**
\* Beatmatching — how to align two tracks in tempo
\* Cueing — how to prepare the next track for a seamless entry
\* Track structure and phrasing — understanding how tracks are built so You know when to mix
The teaching happens live from behind the DJ decks. You can follow from Your seat or gather around and watch up close. CZECH STRINGS demonstrates everything on Electronic Music, but can switch to any other genre on request. The techniques taught apply to all rhythmic music.
A part of the session is dedicated to hands-on practice. You will get the chance to step up to the decks and try it Yourself.
#### **Do You need to bring anything?**
Nothing is required. If You'd like to bring Your own music on a USB stick, You're welcome to, but it will only work if the stick is formatted as MS-DOS (FAT) / FAT32 and the tracks have been analysed in Rekordbox beforehand. If that means nothing to You right now, don't worry. There's plenty of music ready to go.
The atmosphere is supportive, focused, and hands-on. This workshop is for anyone curious about DJing who wants to understand the craft, touch real equipment, and leave with a solid first foundation.
#### **Start where You are. Learn the fundamentals. Find Your sound**.
See You soon.
With Love,
[CZECH STRINGS](https://www.instagram.com/czechstrings/) & DNA.
