Buzzword or not, AI in everyday development cannot be avoided. There is a vast and complicated tooling ecosystem that often makes it more confusing than it should be. We are very happy to host [Dimitrios Papageorgiou](https://www.linkedin.com/in/dimitriospapageorgiou/) , **Senior Solutions Architect at Amazon Web Services (AWS)**, who will give practical tips for the Java developer in the AI assistants era. **📍Location** * Michalakopoulou 80 street, XM * Attendees should say they are there for the Java Athens meetup. **📆 Date & Time** * 4th of February 2026, 19:00 **🗒️ Agenda** * **19:00** \- Intro\, Agenda * **19:05** \- A message from our sponsor \- XM * **19:20** \- "**A Developer's guide in the AI assistants era**" by Dimitrios Papageorgiou * **20:00 -** Q&A Session * **20:15** \- Pizza 🍕 time **Main Talk**: **A Developer's Guide in the AI Assistants Era** Despite the promise of agentic AI, most development teams struggle with adoption due to concerns about code quality and lack of clear implementation paths. Developers worry about hallucinations, incorrect suggestions, and whether AI-generated code meets production standards—concerns that often lead to resistance and superficial proof-of-concepts that fail to deliver value. Furthermore, teams from individual contributors to leadership roles, facing the same common issues: lack of time, pressure to ship to production, fear of the unknown, and reluctance to move from comfort zones. Drawing from my experience as software engineer and from hands-on experience implementing agentic AI tools across multiple customer PoCs, I have worked on a path that addresses these concerns. Whether you're a developer exploring AI tools or a team lead evaluating their potential, you'll leave with a practical roadmap for implementation, strategies to handle team resistance, and realistic expectations for what these tools can accomplish in your daily workflow

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.

Join members of the local UX and Digital Design community for a casual monthly breakfast. There _might_ be a little snow, but there _will_ be effectively infinite serve-yourself coffee, so it evens out if you ask me. Just a reminder, while the other locations are great too, we’re at the Lane Ave one this time.

**Abstract:** The Advanced Photon Source (APS) is an X-ray light source at Argonne National Laboratory where researchers perform imaging, diffraction and spectroscopy experiments at 68 specialized beamlines. APS recently completed a major upgrade that made it the brightest synchrotron in the world and upgraded many of the beamlines to take advantage of the dramatically brighter, more coherent beam. These new capabilities are increasing the facility’s raw data production from <10 PB/year before the upgrade to >100 PB/year once all instruments are back online. To meet this data challenge, the APS Beamline Data Pipeline project team is partnering with beamline staff to develop and deploy science data pipelines that use a common set of open-source software tools (many written in Python) to link instruments with the Polaris supercomputer at the Argonne Leadership Computing Facility (ALCF) for data processing. This talk will describe the APS data systems, our file-based and streaming pipeline templates, and some of the open-source software we use to extract scientific insights from beamline data. **Audience Takeaway:** Open source Python data acquisition and analysis tools are ubiquitous at the APS. Many of the packages that are mentioned can be found at [https://github.com/AdvancedPhotonSource](https://github.com/AdvancedPhotonSource). This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://numfocus-org.zoom.us/j/89399976851?pwd=UEgMUZXdYmKdK1x1dIPL6hwUYnp7NW.1](https://numfocus-org.zoom.us/j/89399976851?pwd=UEgMUZXdYmKdK1x1dIPL6hwUYnp7NW.1) **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
