Deep Reinforcement Learning

Liebe Freunde des gesprochenen Wortes, Ob es darum geht, ein Meeting zu leiten oder im Familienkreis einen Toast auszusprechen – diese Situation vor Menschen zu stehen und etwas zu vermitteln kennt so gut wie jeder. Wir lernen gemeinsam, dabei gelassen und souverän zu bleiben, wertvolle Informationen zu transportieren und unser Publikum zu begeistern. **Was macht unseren Club besonders?** Unser "Mut und Rede" Club trägt nicht umsonst seinen Titel: wir pflegen einen wertschätzenden Umgang miteinander, sodass die Hemmschwelle möglichst gering ist, sich selbst auf die Bühne zu trauen. **Wie läuft so ein Clubabend ab?** Es warten vorbereitete Reden auf euch, aber auch ihr habt die Möglichkeit in geschütztem Raum eine spontan improvisierte freie Rede von 1 bis 2 min vor Publikum zu halten. Das klingt vielleicht im ersten Moment etwas abschreckend – aber es ist eine ganz tolle Erfahrung über sich selbst hinauszuwachsen. Und egal was passiert, ihr werdet immer für Euren Mut belohnt. Und es wird auch immer geklatscht. Wir freuen uns, Euch kennenzulernen! Hier findest du die genaue Wegbeschreibung: www.mut-und-rede.de/kontakt#anfahrt Um besser planen zu können freuen wir uns über vorherige Anmeldung: kontakt@mut-und-rede.de https://www.mut-und-rede.de Es findet grundsätzlich jeder Clubabend statt, auch wenn laut meetup nur wenige Teilnehmer zugesagt haben.

Andere drücken die Schulbank, wir aber wollen in gemütlicher (und realer) Atmosphäre wieder aufeinandertreffen und einen Deutsch-Spanisch-Tandemkurs aufleben lassen. Beim einfachen Zusammenkommen und kennenlernen lässt es sich schließlich viel effektiver lernen. und Spaß haben. ...

Aufs Meditationskissen setzen, Augen schließen und in Glückseligkeit baden. Stellst auch du dir so Meditation vor? Die Realität sieht oft anders aus. Warum? Weil Meditation nichts ist, was man willentlich herbeiführen oder tun kann. Es ist ganz und gar das Gegenteil von tun, nämlich loslassen und sein. Je verkrampfter du versuchst zu meditieren, desto weiter entfernt ist der ersehnte innere Frieden. Aber was kannst du nun tun, wenn du Meditation nicht tun kannst? Du kannst die optimalen Bedingungen erschaffen, dass sich meditative Zustände von alleine einstellen. Wie? komm vorbei am 30.03.2026, 18:30

## Licht und Beleuchtung in der Fotografie – Advanced Der dreitägige Advanced Workshop richtet sich an alle, die ihre Kenntnisse in Licht und Beleuchtung vertiefen möchten. Ziel ist es, komplexe fotografische Setups souverän zu gestalten und umzusetzen. Am **ersten Tag** starten wir mit einer Einführung und einem Portfolio-Review, um individuelle Lernziele zu definieren. Anschließend tauchen wir in unterschiedliche fotografische Stile und kreative Ansätze ein, die inspirieren und die Ideenfindung gezielt fördern sollen. Am **zweiten Tag** bereiten wir das Shooting vor: Von der Bildanalyse über den bewussten Einsatz von Requisiten und Technik bis hin zum präzisen Einleuchten der Location. Dabei stehen die Gestaltungsmöglichkeiten von Licht und Beleuchtung im Mittelpunkt. Am **dritten Tag** folgt die praktische Umsetzung. Jede:r Teilnehmer:in gestaltet ein eigenes Shooting, experimentiert mit verschiedenen Perspektiven und setzt das Gelernte direkt in die Praxis um. Zum Abschluss präsentieren wir die Ergebnisse. Konstruktives Feedback und neue Impulse geben Inspiration für zukünftige Projekte. Voraussetzung für die Teilnahme am Advanced Workshop ist der vorherige Besuch des [Beginner Workshops](https://lette-akademie.de/kurse/licht-beleuchtung-beginner/). ### Kursinformation Anmeldung: https://lette-akademie.de/kurse/licht-und-beleuchtung-2/ Termine: Mo., 30.

Hello everyone, Due to popular request (and some other reasons, like venue availability and available organiser capacity), we’re happy to announce that the Rust Berlin talk meetups are back. This is the classic meetup format: let’s meet in the evening see 2 speakers and then spend some idle time chatting about what we heard. The first speaker for the first edition will be our co-organiser Florian Gilcher, speaking about “Unsafe demystified”, a gentle introduction into handing unsafe code properly. Soares Chen will talk about the current revision of Context Generic, their framework for context generic programming: https://contextgeneric.dev We are also available for new talks, in particular of people who never gave a public talk. We’re happy to be your first talk location. The new meetup is currently organised by Florian and Liran, who is a new co-organiser at Rust Berlin. JetBrains was so kind to offer us their office location as a default meeting point. Thank you! We’re looking forward to getting the ball rolling again! See you all on April 1st! **Line-Up** Unsafe demystified by Florian Gilcher This is a beginner- to mid-level talk that explains the basics of unsafe and how to program it. Instead of going fully into it all details of unsafe, this talk teaches you easy to digest mental frameworks to use when approaching your next unsafe code block. Supercharge Rust functions with CGP implicit arguments by Soares Chen I will give a short overview of the new implicit arguments feature for Context-Generic Programming (CGP), which enables structural typing in Rust. Some short example demos will be presented, followed by some explanation of how the feature works. **Speaker Bios** Florian Gilcher Florian Gilcher used to be part of the Rust team at several positions and served as a member of the Rust Foundation board. He is also a co-founder of the Rust Berlin meetup. Today, he’s training Rust at Ferrous Systems, a company he co-founded. Soares Chen Soares is a Rust programmer with a strong interest in functional programming, type theory, and programming language design. He is the creator of Context-Generic Programming and currently works as a Rust engineer at Tensordyne.

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

Hello! I’m organising a coworking + socialising session for all of us who are working on projects (e.g. our own creations, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have time for both socialising AND working, we will be using the so-called “Pomodoro” technique: **50 mins deep work** (silent), followed by **10 mins break** to socialise. And then repeat! You are welcome to join whatever your personal background is, and whatever project you are working on. I (the host) speak English and German, so either language is fine. ——————————————————- AGENDA: * **Short Intro** Tell us who you are and share something about what you will be working on today * **Pomodoro Session** \- 3x \(3h\) Each Pomodoro session consists of 50 mins focused “deep work” (no talking, no interruptions, **phones on silent mode**) -> then 10 mins break: a chance to share your progress with others -> Repeat * **15 mins Wrap Up** Celebrate what you achieved and get to know others 😊 ———— The location is **Espresso House near Checkpoint Charlie** (they have multiple outlets - so be sure to go to the correct one!) Wifi + power plugs are available - but best to bring a fully charged laptop, just in case 🙃 You **do not** have to pay anything. But since we are using the café space, it is common courtesy to buy at least one drink (coffee costs roughly **4 Euros**).

We're gonna have another Game Creators Hangout! This one is going to be a special one - we're gonna hang out at the ELECTRIC SOCIAL Arcade Bar. We'll have a lot of space, tasty drinks and lots of modern arcades to play. For us they'll do a special deal where you'll get 100 game credits and a drink for 20€. The Hangout is a place where those who create games or are interested in it meet up and talk about whatever they like. Its a place for the community, but also to connect people from different communities. It does not matter whether you're a veteran game dev, just started school or just dabble in creating games in your free time - all of you are welcome here. Accessibility: There is a small step at the entrance. Seating is available inside as well as outside. The arcade area can be overstimulating. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-German\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Es ist Zeit für einen Game Creators Hangout! Dieses mal ist der Hangout wieder etwas besonders - wir treffen uns in der ELECTRIC SOCIAL ARCADE BAR. Da gibts sogar einen special deal für uns - 100 Game Credits und ein Getränk für nur 20€. Der Hangout ist ein Ort, an dem sich diejenigen, die Spiele machen oder daran interessiert sind, treffen und über alles sprechen, was sie möchten. Es ist ein Ort für die Community, aber es geht auch darum, Menschen aus verschiedenen Communities zu vernetzen. Es spielt keine Rolle, ob du ein\*e erfahrene Spieleentwickler\*Inn bist, gerade die Schule angefangen hast oder nur in deiner Freizeit gerne Spiele erstellst - alle sind hier willkommen. Barrierefreiheit: Am Eingang der Bar befindet sich eine kleine Stufe. Es gibt Sitzmöglichkeiten drinnen und draussen. Im Arcade Bereich gibt es laute Geräusche und Lichter, welche überstimulierend sein können.

On the 1st of April we will host the next iteration of our monthly Audio Developer Meetup where **Johan Thelander Lövgren** will be presenting [Ursund](https://ursund.org/), a live-looping & improvisation DAW written in Rust, and **Achillefs Sourlas** will show us how CSound can be used with music plugins, demonstrated with [AutoBeat Machine.](https://axart.net/) See below for details! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd. Talk details: **ursund - a meta-instrument and DAW for live looping and improvisation, written in Rust** \- Johan Thelander Lövgren A cross-platform (desktop/mobile) DAW featuring a dynamic and interactive map of loops, audio effects, modulation, retroactive looping, MIDI, remote control, shared sessions, and more. Johan Thelander Lövgren (aka 'a moment unfolding') is a Berlin-based singer, musician, producer, and sound/software engineer. After moving to Berlin for music studies he became even more enchanted by the many rabbit holes of computer music. Since finishing his studies he has worked for almost a decade as a full stack developer, while building audio projects on the side and performing regularly in the local music scene. **Using the CSound API in a music plugin, demonstrated with AutoBeat Machine** \- Achillefs Sourlas Achillefs Sourlas is an audio developer and musician. He is also the founder of Axart Labs OÜ, an indie music software company based in Tallinn.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

If you enjoy knitting, crocheting, working with yarn, this is the group for you. Meet new friends, bring your projects, learn from others.
We normally meet a few times a month during the week from 6-8pm. We will occasionally meet on weekends during daytime hours.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
