If the author(s) uses GenAIs to prepare technical aspects of the research (e.g., use of GenAI-generated program code in experiments or simulations), this fact must be clearly marked in the paper, along with an analysis of the impact of this approach on the research results. In addition, it is permissible to use GenAI models at the stage of editorial correction, as long as the changes made are minor and do not substantively affect the article. If, at any time after the conference, it will be discovered that an LLM was explicilty used (and not properly recognized) such contribution will be retracted from the post-conference publication. Overall, it should be emphasized that full responsibility for the content of the publication lies with the author(s). Therefore, any inappropriate, or unethical, use of GenAI models in the preparation of an article may result in its immediate rejection.

**The imprints of time: The adventures of a typewriter throughout the 20th century** Once a typewriter created a revolution in writing and communication. After that it became a crucial part of office work that allowed us to quickly write documents. Later - an old and obsolete residue of the past, turning into a small piece of all the things a computer and today’s smart devices are capable of. Now it’s reviving yet again and gives an opportunity to meet itself. We invite you to not just meet the typewriter itself, but also, it’s always-changing world filled with stories. Typewriter – a device that with it’s timeline shows how some mechanism could not just be an innovation of it’s time, but also a part of office work, literature, politics and today’s nostalgia. What can you expect: * A selection of historic typewriters – with their stories and specialties; * An insight into typewriter’s role in society; * Things that lived alongside the typewriter – what they used to write, how they were repaired and where they were produced; Visitors can also try selected typewriters out themselves and take what they wrote along! The number of papers is limited! Meet the typewriters and their rhythmic clicking sounds and the vintage analogue writing experience – that’s not just writing, it’s a whole era or people’s lives. The event will be available from 19:00 up to 00:00, at Sergeja Eizenšteina iela 59a, Riga. Free of admission. *There will be a technical break from 21:00 until 21:30, during which the event will not be available for a visit.* *Filming and photography will be happening during the event with purposes of publicity and protection of the property.*

Come to check out our hackerspace, talk to people and learn some new things, maybe use the tools for a short while, or just sit down with a laptop and do some work in a quiet place. Also a good time to sign up for a membership! We will have tea and coffee, likely also cookies. Come whenever from 19:00 till 22:00 - we might even be open until 24:00!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

**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.

By popular demand, the group wanted to read and discuss the semi-autobiographical novel by Henri-Pierre Roche, that inspired the Truffaut movie we watched last year. The book is available through the Columbus Library's interlibrary loan system. They reported there are twenty-eight copies available in the state of Ohio. If you have a library card, you can file an interlibrary loan request here: https://www.columbuslibrary.org/library-services/ . There are also used copies available on Amazon and eBay for under twenty dollars. You may want to rewatch the movie after reading the book, so we can compare and contrast in our discussion. The Columbus Library has four copies on DVD, and it's streaming on HBOMax.

**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** TBD **YouTube Link** TBD

**Building a great product is one thing—building momentum behind it is another.** Join **Senior Product Manager Adam Solaiman** and **User Experience Manager Tyson Smith** for a behind-the-scenes look at what it takes to turn complex ideas into scalable products inside large organizations. In this session, they’ll share how teams move from ambiguity to execution—navigating organizational complexity, aligning stakeholders, and continuously evolving products after launch. You’ll walk away with insights on how to: * Build and sustain momentum across teams * Adapt to changing priorities without losing direction * Scale products thoughtfully in complex environments Whether you're driving a new initiative or growing an existing product, this conversation will give you practical strategies to keep things moving forward. Come connect, learn, and swap stories with fellow product professionals. \-\-\- Food and drinks will be provided by Switchbox, our generous host. Free parking will be available at the front and back sides of the Switchbox Office.
