### 为什么练习霎哈嘉瑜伽？ 在繁忙的都市生活中，我们往往忽略了身、心、灵的健康。霎哈嘉瑜伽冥想恰恰是现代人的需求。它给予我们瑜伽，即天人合一的状态，通过精微能量来帮助我们恢复内在的平衡。这个修复是自然而然的。 这个力量是我们内在精微系统的一部分，其中还包括了七个能量中心和三条经脉。当我们处于平衡的状态，我们并不受过去或者未来的影响，也能处于无思无虑的状态。而这个力量在梵文中指的是“昆达里尼”。 “霎哈嘉”指的是自然而然，而“瑜伽”的意思是连接联合的状态。霎哈嘉瑜伽仅涉及冥想，并不涉及任何体位瑜伽。 我们的课程： 每逢星期四傍晚7点半 地点：AZ building, 140 Paya Lebar Road, #07-15 Singapore 409015 报名方式：请联系杨小姐（98564587)

\*\* **Registration** **on** **[Luma](https://luma.com/9uwuvfsx)** **is** **required** \*\* As March arrives, let's shake off the CNY food coma and spring into action with fresh Swift ideas! 🌷✨ Join us for iOS Dev Scout's first meetup of 2026 and our very first-ever collaboration with Spatial Singapore! We'll explore new techniques, share innovative approaches, and reconnect with Singapore's vibrant iOS community. Whether you're blooming into iOS development or you're a seasoned dev ready to grow your skills, this is the perfect way to kickstart the year with energy and inspiration! 🗓 **Date & Time**: Thursday, 5 March 2026 🕒 **Time**: 6:30 PM - 8:30 PM 📍 **Location**: Apple Developer Center, Solaris, 1 Fusionopolis Walk, L5 South Tower, Singapore 138632 🌸 What's blooming this March: * 6:00 PM: 🍕 Food, drinks & mingling with fellow devs * 6:30 PM: 🎂 Special Celebration * 7:00 PM: 🎤 10-min host intro & community updates * 7:10 PM: Creating Delightful, High-Performance Animations in SwiftUI - Amit Samant * SwiftUI makes it easier than ever to build beautiful animations but creating smooth, continuous animations that run efficiently at 120 fps requires a deeper understanding of how SwiftUI renders and manages views. In this talk, we’ll explore how to build a slow, infinite panning animation entirely in SwiftUI, and the challenges we solved around performance, memory usage, and GPU-efficient rendering to achieve fluid, production-ready results. We’ll also uncover a few lesser-known animation techniques that unlock surprisingly seamless transitions in real apps. This session is perfect for developers who want to push SwiftUI beyond basic animations and create truly delightful, high-performance user experiences. * 7:40 PM: Diving into Apple Immersive Video - Liu Linxuan (Spatial Singapore) 🧑🏻‍💻 **Speakers** **Amit Samant** Senior iOS Engineer at Rakuten Amit Samant is an iOS Engineer and community leader, serving as an organiser of Swift Bengaluru and Swift Bharat. He has been building iOS apps with a strong focus on mobile platform engineering, app performance, and crafting polished UI animations. **Liu Linxuan**, an immersive videographer who has built a native visionOS application for Apple Vision Pro for viewing Apple Immersive Video, Voola. He has shot amazing immersive video footage of live events including airplane flyovers, rocket launches, and dance concerts, and we'll have an opportunity to experience them ourselves! **💖 Special Thanks** A huge thank-you to Apple for their continued support of iOS Dev Scout — and to you, our amazing community, for bringing the passion and curiosity that makes every meetup bloom! Come with fresh energy and your iOS spirit — let's make 2026 a year of growth and innovation! ✨ **Can't wait to see you there!** The iOS Dev Scout Team Hiring for iOS / macOS?

Hi Everyone, With Covid19 happening, there is still a limited participants for group events of up to 8 pax happening, so this just to keep the virtual skating together going. The Challenge is to skate as much as you can during this pandemic each week. And see how we rank on leaderboard of Strava. The ranking is arranged by most distances skated each week. Do join us through on Strava App below: Leaderboard updates on a weekly basis and resets every week (Mon to Sun) Join us at https://www.strava.com/clubs/freewheelers_sg (Kindly note that with specifically the Strava app, it is unable to cater for Inline skating option, so you will have list your tracking via run or ride for your ranking to show up in leaderboard. And this is the main challenge majority of skaters will be using.) Feel feel to contact Janice on Meetup if you need help with the apps to join us on these virtual skating challenges. You can also ask Janice for link to join a telegram group where impromptu small group skating events are frequently organized if you are looking for skating buddies. Special Note: Heard feedback from some Iphone users that trouble getting apps FOC. All these apps should be free. Please make sure you download the FREE VERSION. And please download the app, before you join via Challenge Links as the Challenge Links lead Iphone users to paid versions I think. Android Phones should be automatic directed to free version.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
