**ANNOUNCEMENT – Registration via this [link](https://go.gov.sg/stackmeetup-2jul2026-mc) only.** Moving AI from prototype to a reliable production often raises questions about optimisation, scalability and compliance. At this STACK Meetup [AI], we strip away the hype to offer an exclusive look under the hood of PlatformAI, GovTech’s developer-first platform built to scale AI capabilities reliably for the Government. Take a peek into how PlatformAI provides an enterprise-ready platform layer to govern and orchestrate large-scale AI model and capability deployments. Our speakers will share strategies on unifying secure model access, balancing costs using Pay-As-You-Go (PAYGO) versus Provisioned Throughput, and leveraging managed multimodal pipelines – Vision, Document, and Audio – without the overhead of maintaining fragmented infrastructure. Walk away with fresh insights on how GovTech is democratising AI deployment at scale, whilst ensuring proper governance like prompt security, throughput optimisation, and architectural guardrails to address modern scaling bottlenecks. **Secure your spot for STACK Meetup [AI] today: [https://go.gov.sg/stackmeetup-2jul2026-mc](https://go.gov.sg/stackmeetup-2jul2026-mc)**.

**ANNOUNCEMENT: [Venue change] SQ Collective has generously offered to host the venue for this session for free. It is only appropriate that we allocate some capacity to them (via a Luma event). This is a chance for folks in the AI builder community to participate in our group’s philosophy practice, and for us to broaden our audience within that community. If you have already signed up via Meetup, there is no need to double-register through Luma, should the Luma event be made public.** “You insist that there is something that a machine can't do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that.” —John von Neumann, in a talk at the Institute for Advanced Study at Princeton, 1948 “Everything is computer!” – Donald J. Trump, sometime in 2025 What is computation? These days, it seems more provocative to stipulate what *isn’t* computation. For instance, to suggest that the brain can be functionally anything other than a kind of computer is suspect in the current technological zeitgeist. It seems self-evident that any system of information processing to achieve some output can be explicated in terms of computation. At the foundation of this conviction is the Church-Turing thesis, which both gave a logical definition to and circumscribed the bounds of computation in the form of the Universal Turing Machine, “a most general formulation of machine” (Alan Newell 1980). The idea that the Universal Turing Machine is an abstract design template that can encompass any kind of information-processing system has led some to extend the scope of the thesis to physics itself: “any finite physical system can be simulated by Universal Turing Machines” (David Deutsch 1985). What do we make of such ideas? Instead of fumbling in the accreted fog of the present, a quiet philosophical dialectic was already underway at the time Alan Turing demonstrated Universal Turing Machines in his seminal paper *On Computable Numbers* in 1936. Ludwig Wittgenstein was a contemporary of Turing’s, and made a number of keen observations in the years that followed\*. In particular, Wittgenstein anticipated readings of the Church-Turing thesis such as the above as resulting from an uncritical acceptance of some inferences within Turing’s demonstration. In this session, we will recount the Church-Turing thesis, its various interpretations, the Wittgensteinian response, and what it all means. Join us to discuss and re-examine the notion of computation, in the hopes of coming to a clearer understanding of it. The format of this session will be a presentation followed by an open-ended discussion. *Compiled in Remarks on the Foundations of Mathematics. By L. Wittgenstein

In this workshop, we explore why building one at home is one of the most practical ways to develop real cybersecurity skills, bridging the gap between textbook knowledge and hands-on capability. We will walk through how home lab concepts map directly to professional cybersecurity environments, and demystify the core terminologies you will encounter along the way — SSH, NAT, VLANs, IP and DNS, virtualisation, Docker, and remote access. Whether you are a student, a career switcher, or an IT professional looking to go deeper, this workshop gives you the foundation to start building with confidence. **LEARNING OBJECTIVES** * Homelab foundations + Quick Threat Modeling * Lets build a simple DNS lab * Monitoring logs * What's next? **SET UP REQUIREMENTS** Bring your own laptops (and laptop chargers) * Install VMware * Download Proxmox Virtual Environment (VE) iso file and install in VMware * Make sure to use NAT Network Mode when installing Proxmox as a guest VM on VMWare **TRAINERS** * Jeremy ([LinkedIn](https://www.linkedin.com/in/jeremyng123/)) * Jun Hong (Dave) ([LinkedIn](https://www.linkedin.com/in/tan-jun-hong/)) **CO-ORGANISERS & VENUE SPONSOR** * [CyberSG TIG Collaboration Centre](https://www.linkedin.com/company/cybersg-tig-collaboration-centre) * [BLOCK71](https://block71.co/) **IMPORTANT NOTICES** * Code of Conduct: [https://www.div0.sg/code-of-conduct](https://www.div0.sg/code-of-conduct) * Terms of Use & Disclaimer Notice: [https://www.div0.sg/terms-of-use-disclaimer-notice](https://www.div0.sg/terms-of-use-disclaimer-notice)

**Delaying age-related diseases: Can the mushroom-derived nutrient ergothioneine prevent dementia?** Distinguished Professor Barry Halliwell host: Kamil Pabis, PhD, co-organized by VIVA foundation As we sit in this room, we are all breathing oxygen (O2), a gas essential for life for efficient energy production from our food. Yet oxygen has a dark side; some of it makes reactive oxygen species (ROS) such as oxygen radicals, which can damage our body tissues, a factor that contributes to age-related diseases, especially dementia. ROS are not all bad, they help protect against infectious disease via the process of acute inflammation (keeping us alive) yet as we age inflammation isn’t controlled properly and the extra ROS cause more damage that contributes to age-related diseases. ROS levels in the body are controlled by antioxidants, many of which we make ourselves but others come from the diet. Most attention has been paid to vitamins C and E, polyphenols and carotenoids. Consuming diets rich in these compounds correlates with better health, but high doses of them as pure compounds in supplements have had little effect in delaying dementia and other age-related diseases in properly-controlled human clinical trials; supplements cannot replace the effects of a good diet. Interpreting correlational studies as causation is often done, but fraught with danger. In the past ten years we have studied a diet-derived antioxidant that has been almost totally ignored, namely ergothioneine (ET). It is found in many foods, but the major source is mushrooms. Our work has demonstrated that ET is likely very important in maintaining brain health and delaying or preventing dementia and other age-related disease, and pilot clinical trials support this. Evidence is growing that ET is a “longevity vitamin” to support healthy ageing, but rigorous clinical trials are needed to prove this. Its effectiveness may be due to its many additional mechanisms to protect our organs, in addition to acting as an antioxidant.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
