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.

**\*\* RSVP here: [https://luma.com/469nzlb5](https://luma.com/469nzlb5) \*\*** System design interviews can feel intimidating, but they don’t have to be. As part of the **Code Mentoring Programme**, we’re bringing together engineers, job seekers, mentors, and mentees for a practical workshop on how to approach system design interviews with more clarity and confidence. Led by **Victoria Lo**, Solutions Engineer Lead and WomenDevsSG Director, together with **Aishwarya**, Community & Programs Lead, this session will walk through a repeatable framework for structuring your answers, communicating tradeoffs, and focusing on what interviewers actually want to see. Instead of memorising patterns, you’ll learn how to apply a method to any system design problem. Through a guided case study, we’ll cover how to: ✅ Break down requirements, entities, and APIs ✅ Sketch a high-level architecture ✅ Dive deep into critical design areas ✅ Practise applying the framework in real time with other attendees 🎯 **Who this is for:** Engineers, job seekers, and professionals preparing for technical interviews who want to build confidence in tackling system design questions. 📅 **Date:** 25 June 2026, Thursday 🕖 **Time:** 6:30 PM – 9:00 PM 📍 **Venue:** The Trade Desk 🔗 **Register to be a mentor or mentee:** Apply by **15 June 2026** → [https://linktr.ee/juniordevsg_mentoring](https://linktr.ee/juniordevsg_mentoring?utm_source=luma) Come ready to learn, practise, ask questions, and grow together. ​**Venue Sponsor:** The Trade Desk

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

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!
