Dynamic Programming

In May, [Bruno Caballero](https://github.com/bruno-ah-um) will show us how to target hardware accelerators from Java with MLIR based on [his fork of the OpenJDK Project Babylon](https://github.com/bruno-ah-um/openjdk-babylon-mlir-tosa). Bruno leads the Java Virtual Machines Engineering team at [MicroDoc](http://www.microdoc.com), which develops JVMs and maintains ports across various processors and operating systems. In this talk, we’ll explore a toy project that translates Java code into MLIR for the TOSA dialect, which is used for AI and accelerator workloads. We’ll briefly introduce current approaches (e.g., TornadoVM and Babylon/HAT), before looking at how this project reuses existing compiler infrastructure instead of building new backends. Finally, we’ll touch on whether DSLs should be embedded in general-purpose languages like Java or designed as standalone languages. Small snacks and drinks will be available. There is always space for outside topics and discussions. If you have specific questions, please bring them. Looking forward to meeting everyone again!

Each session is limited to 8 photographers, so registration is confirmed only after direct contact and pre-payment. **HOW TO REGISTER** Send a DM to @bbphotographyworkshops on Instagram or email info@burakbulut.info Please specify whether you want to join: Ballet Beauty Full-day package **Full information:** **👉 [burakbulut.info/workshops](https://burakbulut.info/workshops/)** **About the mentor:** [instagram.com/burak.bulut.yildirim](https://instagram.com/burak.bulut.yildirim)

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Summer Session, Thursdays, June 4 - July 23, 2026, from 6 to 8:30pm ET **NAMI Family-to-Family** is a free, eight-week program for family members, caregivers, and partners of individuals living with mental illness. NAMI Family-to-Family provides information about anxiety, depressive disorders, schizophrenia, bipolar disorder, and other mental health conditions. Other topics covered include communication, problem solving, treatment, and recovery.

**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 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

We'll get in around 4 miles at Three Creeks Metro Parks, primarily natural trails. 17-18 minute miles, no one left behind, and faster walkers are free to lead out. Optional lunch after! If you're joining for hiking all the metro parks, this is the sixth one!
