In this talk, Anemari Fiser shares the most common challenges tech leads bring into coaching sessions - overload, unclear expectations, ownership confusion - and assumed alignment, and why “getting better technically” almost never fixes them. Drawing from real coaching and training examples, the talk explores where tech leads get stuck, what they think the problem is, and the small but meaningful shifts that help them move forward. **19:50: Drinks and networking!** Do you want to talk at this meetup?

**TORNEM A LA CIUTADELLA!!** **NO us equivoqueu de lloc!** **[QUÉ ES EL SOFTCOMBAT?](https://youtu.be/Essu82NpRvc)** **[Qué es el Jugger? | El Jugger, qué es y cómo jugarlo](https://youtu.be/dfyrlQn14oM)** **[Qué es el LARP?](https://youtu.be/fB3FkxDZhBA)** El Softcombat és una activitat esportiva en la qual, mitjançant armes embuatades (conegudes com boffers), es recreen combats medievals, es practiquen jocs d'equip i s'aprenen moviments marcials de combat.

Si t'interessa aprendre a combatre, emular les lluites de les teves pel·lícules favorites, lluitar amb espasa, subjectar un escut, dominar els secrets de l'equilibri de peus o fer fitnes d'un mode diferent; el Softcombat i el Rol en Viu són una activitat que has de provar. **És durant el matí de 11h a 13.30h quan major quantitat de participants es reuneixen. A la tarda, es queda(a vegades) un petit grup, però no es pot garantir la seva presència fins a les 18h, sobretot a l'hivern.

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.

Come out to Improving for our monthly iOS and Mac meetings. This Month's Presentation: Nothing yet. (You should volunteer). What is Cocoaheads (http://cocoaheads.org/)? CocoaHeads is a group devoted to discussion of Apple Computer's Cocoa Framework for programming on MacOS X and iOS (including the iPhone, iPad and Apple Watch). During monthly meetings, members present on their projects and offer tutorials on various programming topics. What is BuckeyeCocoa (http://buckeyecocoa.org/)? BuckeyeCocoa is a group of Objective-C/Swift developers/enthusiasts. We host monthly Cocoaheads and near-weekly NSCoder meetings in Columbus, Ohio. The meetings are free to attend. Presentations! Presenters welcome! We are always in need of people willing to present material. Any Swift and/or Objective-C related topic is welcome. Times can be 5 minutes (i.e. lightning talks) to a maximum of 2 hours. Interested? Contact info is on the BuckeyeCocoa website. To volunteer for a presentation contact us at @BuckeyeCocoa on Twitter. Follow us on Twitter! @BuckeyeCocoa (https://twitter.com/#!/Buckeyecocoa/) For more information: http://buckeyecocoa.org/

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
