**Special topic for this week: TODO!** Have you ever wondered what happens after you write your program in any programming language and hit "Run"? Welcome to the new group dedicated to Compiler Engineering so we can discuss language design, static analysis, VMs, and code generation. Topics related to hardware architecture and FPGA are also welcomed! **Join us weekly and learn about:** * The vision for this group. * A crash course on how to start learning compiler dev (including top book recommendations). * An open networking session for showcasing projects and finding collaborators. * Weekly topic to learn about particular aspect of programming languages or hardware **Who is this for?** * Anyone building DSLs or new languages. * Anyone curious about low-level systems and programming * Anyone hiring for compiler/toolchain roles (come pitch your jobs!). * Anyone who wants to learn more about programming languages nature! This isn't a lecture—it's a conversation. Come share your projects and get motivated! This group is not super serious, so if you want to just yap about how bad is the new C++ standard you can find some listeners here. See you!

Dinner will be provided to all workshop attendees. — **ABSTRACT** **From Curiosity to Capability: Build Your First Home Lab** A home lab is a personal computing environment you build and run yourself — a sandbox to experiment, break things, and learn. 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)

**DISCLAIMER: NOT FINANCIAL ADVICE** Casual run of about 3.5km - 4km. Hais, seems like there isnt a a community run group on bitcoin in Singapore. Please visit below page to sign up (Dont pangseh hor). https://www.meetup.com/runningbitcoinsg It is the only way I can filter out the bots. There is always more things to learn about Bitcoin. One of it being low time preference. The group welcomes anyone who is interested in knowing more about saving in bitcoin or simply just want to join us to have a good run.

**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

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.

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!
