**ANNOUNCEMENT – Registration via this [link](https://go.gov.sg/stackmeetup-25jun2026) only.** Singpass is the backbone of Singapore's national digital identity, but what does it actually take to run, scale, and evolve the infrastructure beneath? In this engineering-focused Meetup, we'll trace the evolution of Singpass’ infrastructure from its early days to the present. Deep dive into the modern architectural strategies being deployed today by the team to ensure that this critical digital product is secure and resilient by default. Moving past the buzzwords, we will dissect what truly constitutes PaaP or Platform as a Product, and pull back the curtain on the real-world realities of leading a platform engineering team. Whether you are currently building internal tooling or seeking inspiration on scaling your cloud-native systems, this session will challenge you to rethink how your organisation can approach infrastructure.​ Who should attend: ​​Software Engineers, Cloud and Infrastructure professionals, and Product Managers working on infrastructure platforms. Attendees should have a basic understanding of Kubernetes or Cloud Service Providers. **Programme** 6:30pm: Networking 7:00pm: Introduction By STACK Community 7:05pm: Opening By Tay Li Soon, Deputy Director, Product Management and Head of Product, Singpass, GovTech Singapore 7:15pm: What’s In A Platform?

This month, we return to the crowd-favourite topic of Agentic Systems & Harnesses! Talks: **"Patterns of Successful Agent Harnesses" - Sam Witteveen** In a talk he previously delivered at Google Cloud Next in Las Vegas, Sam will focus on the core patterns and components of successful agents and harnesses, covering patterns from coding agents like Claude Code & Codex through personal agents like OpenClaw & Hermes. These patterns clearly show what is working in building modern agents. **"Trying to download more RAM for my life" - Raghav Bhardwaj** In this lightning talk, Raghav describes his month-long journey hacking in OpenClaw to build a personal agent OS. He goes over changes made for continuity across hundreds of projects, and turning scattered chats, files, tasks, tools, and memories into a working loop that can keep up with the mess. **"Local Models & Self-Evolving Harnesses" - Martin Andrews** In his talk, Martin will first explain how a number of the recently announced self-updating harness systems work. Then, in light of the recent turbulence in the world of Foundation Models, he'll talk about Local Models, and how to increase business robustness. **FOOD UPDATE :** Google has told us that **there WILL BE** pizza at the event \-\-\- Talks will start at 7:10pm (entry at 6:45pm) and end at around 9:00pm, at which point attendees can come up to the front for a bit of a chat with each other, and the speakers. Due to some recent security incidents at the venue please take note of the new DevSpace security procedures [https://bit.ly/devspace-security](https://bit.ly/devspace-security) Attendees will not be admitted later than 15min after the talks have started. As always, we're actively looking for more speakers - both '30 minutes long-form', and lightning talks. For the lightning talks, we welcome folks to come and talk about something cool they've done with keras, PyTorch, JAX and/or Deep Learning for 5-10mins (so, if you have slides, then #max=10). We believe that the key ingredient for the success of a Lightning Talk is simply the cool/interesting factor. It doesn't matter whether you're an expert or an enthusiastic beginner: Given the responses we have had to previous talks, we're sure there are lots of people who would love to hear what you've been playing with. If you're interested in talking, please just introduce yourself to Martin at one of the events.

### 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)

If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

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
