Data Science using R

How does a developer move from hobby projects and university assignments to building **production systems that are reliable, scalable, and environmentally responsible**? In this **lightning talk and storytelling discussion**, we explore the transition from experimental coding to professional software engineering. Through short, focused talks and conversation, we’ll look at what it takes to turn ideas and side projects into **real-world applications designed for sustainable delivery**. During the discussion we will explore: * The transition from **hobby coding to professional engineering** * Lessons learned when moving from prototypes to **production-grade systems** * Building and scaling **engineering teams in an international environment** * Integrating **sustainability and efficiency into software delivery** * Opportunities for developers to grow within **diverse engineering communities** If you are interested in expanding your network, working in diverse engineering teams, or exploring opportunities in sustainable software development, this session will offer practical insights and inspiration. Join us to hear real stories from engineers building systems and communities right here in Budapest.

Dear all, we’re back with the PyData meetups, focused as always on sharing best practice, methodologies, analysis, machine learning systems, .., with the open-source projects of the [NumFOCUS](https://numfocus.org/sponsored-projects) program — but not only! We’ll meet **#InPresence on Thursday, April 30 at 7:00 PM**. We’ll be hosted by [Anda Venice Hostel](https://www.andavenice.com/) in the Medusa Room and, for those who cannot join us, it will also be on YouTube in **#streaming**. 👥 We’ll have two interesting sessions in English 🇬🇧: 🗣 [Tomas Scagliarini](https://www.linkedin.com/in/tomscag/) studies the **#analysis** of Earth’s tipping elements that is crucial for understanding the **#stability** of the **#ClimateSystem**. He will discuss how the interdependencies among tipping elements evolve over time under different anthropogenic forcing. 🗣 [Babatunde Monye](https://www.linkedin.com/in/babatundemonye/) will present a **#MultiTimeframe** algorithmic trading **#signal** system built on probabilistic confidence **#model**, combining momentum, adaptive smoothing, and convergence & divergence indicators to generate structured buy/sell signals across multiple asset pairs. And afterwards\, for those who want\, we’ll stay there for \( 🍸 \| 🍺 \) & \( 🍕 \| 🍔 \) and **#networking** until late ‼️ 📽 And if you’d like to share ideas, projects, topics, or propose yourself as the next speaker, here’s the usual [Google form](https://forms.gle/rVMWxFnodHaNb9ab9) or [Sessionize](https://sessionize.com/pydata-venice-2025-12-18) !

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

**We'll have two meetings covering AI - this second one is for Positron** We will review which AI features are linked in for Positron, and how to use them. **Source documents:** the repository is public, at: https://github.com/BarryDeCicco/AARUG_2026_04_09_AI_In_Positron You can download documents, or clone/fork the repository. **Location:** The meetup will be at SPARK's ([https://annarborusa.org/](https://annarborusa.org/)) Ann Arbor site: [SPARK HQ (Ann Arbor)](https://urldefense.com/v3/__https://www.google.com/maps/place/Ann*Arbor*SPARK*Headquarters/@42.2792515,-83.7447708,17z/data=!3m1!4b1!4m5!3m4!1s0x883cae3effe193cb:0x5296a53db2a282bf!8m2!3d42.2792515!4d-83.7447708?hl=en-US__;Kysr!!HXCxUKc!3EEdBNXRJKknP6LCGkZetSuEsdtChFojQnOVitFUC5C0fyilqXEbiMstT9ajBR3Cw-55qoFkrElCjQvjMdTxUw$).

Central Ohio Radio Enthusiasts—CORE—is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. Ham radio operators, GMRS users, Meshtastic fans, software-defined radio nerds, makers, and technical and non-technical folks are all welcome. No experience required or expected. This month we have **Radio Signal Analysis Using SDRs and OpenWebRX+** with **Scott McCrory**. Details are are [core.radio](https://core.radio/).

Some trained COUNT volunteers work together once a month at RMH (http://www.rmhc-centralohio.org/volunteer.php) as Housewarmers (usually on the 1st Sunday from 1 – 5 PM). Some schedule other shifts at their convenience. You may try this out with less fuss by following a "Fast track" or go through the normal process. Fast track • Arrange a time to shadow a COUNT volunteer. Call Dave Nohle at 614-268-9558 (cell). • Show up and try it out. • Complete application, etc. later. Normal process • Complete an online application (http://rmhc-centralohio.org/volunteer/). • Attend orientation in advance. • At orientation you will complete forms agreeing to keep family/patient info private and allowing a background check and tour the facility. • Complete one training shift. Daily shifts are: morning 9 AM - 1 PM, afternoon 1 - 5 PM and evening 5 - 9 PM. • Schedule shifts online using the on the RMH scheduling system (http://www.volgistics.com/ex/portal.dll/?FROM=32895). The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014. Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.

It feels like we just saw each other 🤷. Join members of the local design and UX community for our monthly breakfast. For May we’re stopping in for Rooh’s popup breakfast/cafe concept. You know someone is getting the lobster yuzu croissant, and that’s not even the prettiest thing on the menu!.
