PyBerlin 59 - March event
**PyBerlin: March event**
**Sponsor**: Spiced Academy
**Location:** Spiced Academy, Ritterstrasse 12-14, 10969 Berlin, Germany
**Agenda:**
6:30 pm – Doors open: snacks, drinks, networking
6:55 pm - Welcome from PyBerlin
7:00 pm - Welcome from the sponsor - Spiced Academy
**7:10 pm** – **What Actually Changes Customer Behavior? Causal Thinking Across Attribution, Segmentation, and Growth // Dr. Maryam Ramezani-Bartsch**
Customer data is often used to explain what happened: attribution assigns credit, segmentation groups users, and dashboards track performance. Yet marketers and business leaders still struggle with a more fundamental question: what actually changed because of our actions?
This talk introduces causal thinking as a practical way to interpret customer data across attribution, segmentation, and growth. It shows why correlation-based metrics can be misleading and how counterfactuals and incrementality help teams ask better questions when they look at results. A concrete email campaign example illustrates how causal uplift modeling separates customers who would have purchased anyway from those whose behavior truly changed.
The goal is to help data scientists, marketers, and decision-makers move from reading metrics to reasoning about incremental impact and to make better decisions because of it.
Speaker's bio:
Dr. Maryam Ramezani-bartsch is a data and analytic leader with over 20 years of global experience building and scaling customer analytics and data science teams. She has led the development of customer data, marketing measurement and targeting capabilities for global brands such as adidas, Sky, Delivery Hero, and Zalando, helping embed customer-centric, data-driven decision making across organizations. Her work focuses on building customer data models, causal analytics, experimentation, and developing teams that turn insights into sustained business impact.
**7:40 pm - Python 3.14 & 3.15 news! // Hugo van Kemenade**
The release manager will share some of the exciting things in the newest versions of your favourite programming languages.
**7:50 pm - break**
**8:10 pm** – **Your Next On-Call Engineer could run Locally //** **Anthony Alaribe**
What if your next on-call engineer wasn't a person, but a Python agent running on your machine?
Inspired by the explosion of local agents like OpenClaw, this talk explores what happens when we point agentic workflows at the systems we monitor.
We'll walk through the checklist most engineers actually run during on-call: checking dashboards, tailing logs, correlating errors with recent deploys, and then explore how to build a custom Python agent that automates these checks using tools like LangGraph, OpenTelemetry, and the Anthropic SDK.
You'll leave with a working starting point and a new way to think about what agentic AI can do beyond chatbots.
Speaker's bio:
Anthony has spent over a decade building software at companies like Opera, and DeliveryHero. He has faced his fair share of dealing with unreliability software and breaking changes in APIs, including losing over $2m in orders to such an incident, amongst other war stories. Say hi when you him. He loves conversations about AI, databases, and programming languages.
**8:40 pm – What makes XGBoost so powerful // Rakibur Rahman**
XGBoost (Extreme Gradient Boosting) is one of the most influential machine learning algorithms of the last decade, originally developed by Tianqi Chen. It has become the default choice for structured (tabular) data problems, widely used in both industry and data science competitions on platforms like Kaggle.
This talk explains why XGBoost works so well, from both a mathematical and practical engineering perspective.
Speakers bio:
Rakibur Rahman, PhD is Senior Coach of Data Science & AI at Neuefische/Spiced Academy, Berlin, with 20+ years of analytical problem solving and data analysis experience. With a background in Theoretical Physics, he is keen to apply cutting-edge machine learning algorithms and AI tools for driving positive business impact. Endowed with the ability to present complex ideas in simple pedagogical form, he delivered 50+ professional talks at the international level. His global experience includes working/studying in the USA, Germany, Italy, Belgium and Bangladesh.

Philosophie 2.0 - spielerisch klug durch maximale Klarheit
Mit dem Titel "Philosophie 2.0" wird nicht zu viel versprochen.
Nicht alles was mit 'Philosophie' bezeichnet wird, hat damit auch zu tun.
Das gilt allgemein.
Wörter werden zu oft nicht präzise gebraucht, aber wenn man alles mit beliebigen Wörtern bezeichnen würde, könnte man nichts mehr genau verstehen, könnte nichts mehr genau begreifen. Also blieben die Irrtümer bestehen. Das hätte mit Philosophie aber definitiv nichts mehr zu tun.
Was also ist das Gegenteil belanglos-vieldeutigen Wörterverdehens mit hochassoziativen Sprüngen bei denen allerlei übersehen wird und ergo das Wesentliche nicht mehr als solches klar erkannt werden kann?
Maximal exakte Begriffsklärung.
Und das geht!
Das geht über einen systematischen Aufbau aller Kategorien - gestützt über einen Algorithmus, welcher Kategorienfehler automatisch vermeidet und mithilft, das Ganze im Blick zu behalten.
Dass dies für uns Personen gar nicht so einfach ist, sieht man daran, dass jede Person (auch Du) irgendwann irgendwelchen Irrtümern aufgesessen ist.
Jede Person, die sich also für irgendetwas ernsthaft (nicht wegen blanglosem Amüsement, oder wegen ideologischer Rechthaberei) interessiert und ergo dafür offen ist seine Auffassungen weiterzuentwickeln, ist bei dieser Veranstaltung goldrichtig.
Ablauf:
Bei unserer Diskussion geht es dabei nicht um irgendein festes Thema, sondern jeder schreibt ein Wort in seinem Interessengebiet auf einen Zettel und wir ziehen diese paarweise für je eine Runde.
Die beiden Wörter haben gemeinsame Kategorien, aber es gibt auch Unterschiede.
Wer diese nicht alle kennt, kann nicht behaupten, dass er tatsächlich begriffen hat, wovon er meint, dass es ihn interessiere; dass er definitiv wüsste wovon er spricht.
Dieses Problem hatte schon Sokrates erkannt. Nur haben wir jetzt einen Algorithmus, welcher zu absoluter Genauigkeit verhilft um diese Irrtümer loszuwerden. Daher 'Philosophie 2.0'.
Siehe dem Bild oben werfen wir die Bedeutung (die Menge aller Kategorien einer Begrifflichkeit) per Beamer an die Wand.
Wir sind nicht in der Schule, d.h. es gibt keinen Zeitdruck, keine Noten, keinen Wettbewerb und keine Profilierungsmotive, sondern jeder hat alle Zeit der Welt um über die schematisch dargestellte Bedeutung nachzudenken - und diese zu hinterfragen.
Die grafisch dargestellten Bedeutungen des Algorithmus sind nicht perfekt.
Es geht nicht darum irgendetwas zu akzeptieren, sondern andersherum: die Bedeutung anzugreifen und zu verbessern.
Jeder kann sie ändern!
Die Diskussion ist also eröffnet. Jeder muss Gründe angeben.
"Kann ein Walfisch ein Wellensittich sein?"
\~> Natürlich nicht, denn Säugetiere sind keine Vögel.
"Kann ein Fenster ein Getränk sein?"
\~> Jeder weis, das ist unmöglich, denn Festkörper sind keine Flüssigkeiten.
"Kann eine Demokratie eine Republik sein?"
"Kann eine Vermutung eine Meinung sein?"
"Ist etwas zu begreifen das Selbe wie etwas zu verstehen?"
Nichts regt dermaßen zum nachdenken an wie die Bedeutung der Begrifflichkeiten algorithmisch stabilisiert zu systematisieren.
Und wenn wir uns nicht einig werden?
Die Diskussion läuft auch nach der Veranstaltung weiter. Jeder kann online von zuhause die Diskussion fortführen - mit dem selben mitdenkenden Algorithmus.
Man könnte sagen, es sei ein neues Gesellschaftsspiel - ohne Wettkampf, sondern in kollektiver Bereicherung an Klarheit, von der alle gigantisch profitieren, obschon jeder nur einen sehr kleinen Teil beiträgt.
Das "Spiel" funktioniert auch mehrsprachig, denn der platonische Raum der Begrifflichkeiten ist der eindeutige Raum, auf den das Vokabular einer Sprache nur referiert.
Man kann auch von Zuhause aus online mitmachen. Den Zugang können wir dann über die Kommentare hier organisieren.
Bring deinen Laptop mit, dann wird es einfacher...
Dieses Spiel macht klug:
Schach trainiert zwar das Konzentrationsvermögen, hat aber mit der Wirklichkeit nichts zu tun.
Dieses Spiel hingegen schon, denn genau mitdenken zu können setzt voraus genau zu unterscheiden.
Wer die Bedeutung der Wörter sauber ausdifferenziert wird immer klüger.
Mach mit!
Soundground: free improvised music workshop
**A place to meet sound, without maps**
Facilitated by **Vesti Gium (they/them)**
Everyone enters as they are.
No score. No threshold of skill.
We follow the room, moment by moment—
listening, nudging, letting the music find itself.
A breath, a shoelace, a laugh, a footstep—
each carries weight.
Silence is welcomed; noise is celebrated.
There are no wrong directions here.
We practise a listening that reaches outward and inward:
to ourselves, to one another, to the space we shape together.
That is where the music begins.
* 🌀 Bring a voice, an object, an instrument, a movement—or nothing at all.
* ✨ **Priority given to FLINTA folks and people with migration backgrounds.**
* 🎧 No experience needed. Curiosity is enough.
* 📍 Berlin – \[theodorstraße 5,12099]
* 🗓 Every Wednesday 17: 30
* 📬 DM or email **[vestigium.impro@gmail.com](mailto:vestigium.impro@gmail.com)** to join
Come make sound—come be heard.

Rust Berlin on location 🏳️🌈 - Edition 012
**Rust Berlin on location 🏳️🌈** is a new, informal in-person Rust meetup group in Berlin.
We are a interactive meetup format interested in mob coding, deep diving and problem solving together.
We build toy projects, share experiences, discuss technology and learn new cool stuff.
And you are welcome to join!
No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome!
To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️🌈](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)**[ Zulip chat](https://rust-berlin.zulipchat.com/join/gap4pdbz7xsquliiz7tgcyuk/)!
**Planned programme**
Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A.
With the [introduction](https://berline.rs/2026/04/01/berlin-talks.html) of the new [Rust Berlin Talks](https://berline.rs/about#rust-berlin-talks) meetup series, **[Rust Berlin on location 🏳️🌈](https://berline.rs/about#rust-berlin-on-location)** strengthens its focus on social community experience, the exchange of knowledge, ideas and perspectives, and the joy of spontaneity.
This time, we will try a new interactive discussion format: Jonas will introduce the topic of *The Job Market and AI* with an impulse presentation, then open up a moderated discussion with all participants. Let’s see where this hot topic leads us!
If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that!
Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere.
**Projected upcoming meetups**
We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks).
19 March 2026 is our twelfth meeting. Our next projected meetings are going to occur on the following dates:
* 16 Apr 2026
* 14 May 2026 (tentative, public holiday)
* 11 Jun 2026
* 9 Jul 2026
* 6 Aug 2026
* 3 Sep 2026
**Location**
Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people.
We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup.
Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead.
As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot!
**Accessibility**
The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space.
On our quest for a bigger location, we are going to pay special attention to accessibility.
**Community**
We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/).
Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can.
We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the Berlin Rust Hack and Learn online meetup's [Matrix channel](https://matrix.to/#/!xycQxSjSAvEezkyztA:chat.berline.rs). You are very welcome to join!

From Web Forms to Web Components - Burton Smith
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
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.
