Data Mining

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, February 26 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 : [Alejo Nahuel Rossia](https://www.linkedin.com/in/alejo-rossia-2a1881225/) will present SMEFiT, a fully **#BayesianAnalysis** package for high-dimensional inference. The talk will cover its physical motivation, technical architecture, and efficient sampling via **#NestedSampling** and **#JAX** parallelization. [Mario De Nisi](https://www.linkedin.com/in/mario-de-nisi/) will present **#Trading** Lab, a **#DataDriven** system for real-time **#portfolio** simulation using predictive models and multi-timeframe features. The talk will explore how implicit definitions of **#risk** and return can be derived directly from data, reducing heuristic assumptions in **#DecisionMaking**. 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) !

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.

If you're tired of swiping left and right on dating apps, speed dating is a great way to meet new people in person, in a relaxed, safe, and comfortable environment. **HOW IT WORKS:** We'll introduce you to at least 5, and up to 12 - or more - single women or men. Spend a little time with each one, during a series of 6-minute Pre-Dates. Then tell us who you'd like to speak with again & we'll do the rest! It's the modern, civilized, effective, and fun way to meet other professional-level singles. If you're finished with the games and ineffectiveness of online dating and apps, join us to share a wonderful evening of enjoyable conversation with interesting people... and maybe something magical will happen! **GET TICKETS:** A Meetup RSVP is not a ticket, you must purchase on our website. [https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup](https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup) Use Code MATCH5 for $5 off! **DOES IT WORK?** Yes! According to the New York Times, at a speed dating event, people like 2-3 out of 10 people they meet. Online daters only match with 1 in 100 or fewer of the profiles they study. This is the best way to meet new people, and it works! Just ask the thousands of people that have met at our events and had successful relationships and marriages. **WHAT DOES IT COST?** We put a lot of time and effort into creating the best singles events possible, so we collect a fee for our hard work. Our events are an excellent value at about $3 per introduction. Get your ticket for the best singles event in town. **NOTE FOR NEWCOMERS:** We post our events on various platforms. Our events often sell out, so expect plenty of fellow singles, regardless of the numbers you see here :) So what are you waiting for? Join us for some fun conversation with great new people... and maybe something more! Who will you meet? **GET TICKETS:** [https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup](https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup) #singles #singlesevents #speeddating #love #relationships

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
