(English version at the bottom) Arjen ihmissuhteissa pienetkin tilanteet voivat helposti herättää ärtymystä, puolustautumista tai väärinymmärryksiä. Saatamme reagoida nopeasti tai jäädä kiinni omaan näkökulmaamme. Tässä meditaatiossa tutkimme, mitä tarkoittaa tuoda rakastavaa ystävällisyyttä tavallisiin kohtaamisiin – kumppanin, ystävien, työtovereiden tai tuntemattomien kanssa. Mitä muuttuu, kun kohtaamme toiset hieman avoimemmasta ja kärsivällisemmästä paikasta käsin? 𝐌𝐢𝐤ä 𝐨𝐧 𝐦𝐚𝐚𝐧𝐚𝐧𝐭𝐚𝐢 𝐦𝐞𝐝𝐢𝐭𝐚𝐚𝐭𝐢𝐨? Maanantain meditaatio on viikoittainen zen-harjoitus. Harjoittelemme yhdessä meditaatiota ja tutkimme joka kerta yhtä aihetta, joka voi avata uusia näkökulmia omaan mieleen ja elämän kokemiseen. Harjoitus voi tuoda lisää selkeyttä, rauhaa ja tasapainoa sekä meditaatiossa että arjen tilanteissa. 𝐌𝐲ö𝐭ä𝐭𝐮𝐧𝐧𝐨𝐧 𝐭𝐞𝐞𝐦𝐚 Tämä ilta on osa myötätunnon ja mettameditaation teemaa, jota tutkimme maanantain meditaatioissa 23.3.–20.4.

Aikaisempaa kokemusta meditaatiosta ei tarvita.

We may react quickly, close off, or hold on to our own view. In this meditation we explore what it means to bring loving-kindness into these ordinary encounters — with partners, friends, colleagues, and strangers. What changes when we meet others from a slightly more open and patient place? 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐌𝐨𝐧𝐝𝐚𝐲 𝐦𝐞𝐝𝐢𝐭𝐚𝐭𝐢𝐨𝐧? Monday meditation is a weekly Zen practice. We meditate together and each week explore a new topic that can open new perspectives about our own mind and our experience of life. The practice can bring more clarity, peace, and balance — both in meditation and in everyday life. 𝐂𝐨𝐦𝐩𝐚𝐬𝐬𝐢𝐨𝐧 𝐭𝐡𝐞𝐦𝐞 This evening is part of the theme of compassion and metta meditation, which we will explore in Monday meditations from March 23 to April 20.

We’ll discuss practical strategies for integrating AI while preserving human expertise, along with actionable approaches to upskilling teams for an AI-driven workplace. Drawing on real-world experience from training thousands of professionals and deploying AI solutions, this session will provide clear, applicable insights for today’s evolving landscape. Following a short presentation, the session will open into an interactive discussion where attendees can share perspectives and explore key questions around the evolving role of humans, organizational adaptation, and staying competitive in an AI-first world. **Who should attend:** • Executives and managers in SaaS, consulting, and knowledge-driven organizations • Professionals exploring AI upskilling and workforce transformation • Anyone interested in the future of AI and knowledge work 📍 **Location:** Data Science Dojo, 5010 148th Ave NE, Suite 200A, Redmond, WA, United States 🔗 **Google Maps:** [https://lnkd.in/d8WA-yNc](https://lnkd.in/d8WA-yNc) **💻 Online Access:** A livestream will be available for those unable to attend in person; however, the full interactive experience is reserved for in-person participants.

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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.
