Data Science using R

LFU looks deceptively close to LRU: both caches evict the "least useful" item. We'll look at how the ordering rule affects data structure design. We'll discuss the algorithmic tradeoffs behind LFU and compare different implementation strategies, ending with benchmarks in C++ and Rust.

Open Heart Meditation Sessions with Amrita Rani (Live in-person and online on selected Thursdays via Zoom) You are warmly invited to join the Open Heart Meditation Sessions with Acharya Amrita Rani — a living space of awakenings and direct experience. These sessions are created both for beginners and seasoned practitioners who wish to deepen their meditation practice, stabilize awakening, and walk the path of enlightenment with guidance and support. Whether you are new or experienced, each gathering offers a grounded structure to help you build consistency in daily practice and grow in confidence on your spiritual path. At the heart of Open Heart teachings is direct recognition. Through the Two-Part Formula and precise meditative guidance, you are supported in shifting from self-based mode into selfless awareness, again and again, until cessation of suffering takes place. A central and deeply transformative practice in Open Heart is guru yoga. Through guru yoga, the practitioner directly connects with awakened awareness through devotion, transmission, and experiential recognition. With the help of this profound method, one recognizes their true selfless ease, the natural, effortless state beyond space and time. Alongside guru yoga, the sessions include insight meditation (Vipashyana), tantric methods, dynamic concentration, trauma-healing techniques, and foundational practices such as Bodhicitta prayers. Each session includes guided meditation, space for questions, reflection, and personal support. Rani’s meditation sessions are held live on Zoom on selected Thursdays from 18:30 to 20:00 (CET). Recordings may be available for continued integration and practice on her YouTube channel, The Sweetness of Enlightenment.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
