Join us for a **casual, low-structure, relaxed** 1.5-hour writing meetup designed for writers who want to connect with others in a supportive, no-pressure environment to come and go as you wish, whenever. Whether you're a poet, novelist, blogger, or write in non-natural languages, we welcome every night owl! **What to Expect:** Nothing structured, this is a casual Schelling point for people who happen to write at night. If you are looking for a large group, high-effort, strongly organised event, this is probably not the one for you. If there are new members joining us, we'll start with some introductions, dive into focused writing time on your personal project, and then, optionally, share a short reflection about our writing at the end. **What to Bring:** * A writing project * Something to write with (notebook and pen, laptop, tablet - whatever you prefer) * A curious mind **Finding Us:** Look for the corner table

**\*\*\*ATTENTION\*\*\*: You need to register in the below link to attend the meetup** **Register here:** CLOSED We are delighted to announce that our next meetup will be in cooperation with Maven Securities. Special thanks to our sponsor for F&B. **Special Episode: This event comes with 2-hours of CPT certificate.** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Speaker 1:** Yunbo Ni **Topic:** Beyond Generic Coding Agents: Agentic Code Review for Critical Software Systems **Summary:** Modern software infrastructure increasingly depends on large, complex, and fast-evolving codebases. Compilers are a representative example: they sit underneath trading systems, networking stacks, AI infrastructure, and many other performance-critical applications, yet subtle compiler bugs can silently propagate into downstream systems. In this talk, I will use compiler reliability as a case study to discuss how agentic code review can be designed for real-world, high-stakes software systems. In this talk, I will introduce Archer, an agentic code review framework for LLVM. Instead of relying on a general-purpose coding agent, Archer combines domain-specific knowledge, compiler-aware reasoning, and a customized validation harness to inspect compiler changes and produce reproducible reports. In our evaluation, this specialized design is significantly more effective than general commercial review tools such as CodeRabbit and Greptile in identifying potential semantic issues in compiler optimizations. Beyond compilers, this talk aims to share broader lessons on building effective agents for large systems: how to decompose expert workflows, how to design tool-using agents, how to build reliable validation harnesses, and why domain-specific agent infrastructure can outperform generic AI coding assistants. **Bio:** He is a PhD student in Computer Science at The Chinese University of Hong Kong, advised by Prof. Shaohua Li.

Our team was tasked with replacing their manual forecasting process with a modern machine learning framework that combines an automated workflow, robust predictive models, and an actionable dashboard seamlessly integrated into their existing infrastructure. In this presentation, we will walk through the key stages of a corporate data science project, including data preparation, model development and fitting, and the consumption layer. We will also discuss the role of MLOps in ensuring reliable model deployment and ongoing maintenance, as well as potential future integrations to enhance business impact. **Bio:** He is a senior data analytics consultant with over a decade of experience applying AI and machine learning to solve real-world challenges across consulting, finance, government, and research in Europe, theUS, and Hong Kong.

However, mapping colloquial language to standardized terminologies such as MedDRA using large language models (LLMs) often produces hallucinated terms or codes.
This talk presents a framework to mitigate hallucinations by grounding LLM outputs in external knowledge and rigid constraints. The resulting methodology provides a reproducible and reliable approach to ADR detection and normalization, demonstrating how retrieval-augmented generation (RAG), dense reranking, and output-level constraints can together overcome the hallucination problem. **Bio:** A PhD student in Computational Linguistic and Natural Language Processing study. My research interests are Knowledge Engineering, Ontology, and LLMs in Healthcare.

Unlike the usual BYOB format of this group, this is an **assigned reading format.** **You are expected to have read some of the book** to join the discussion :) About the book: # Get an accessible introduction to quantum computing as a mathematician explains quantum algorithms, quantum entanglement, and more. Quantum computing is a beautiful fusion of quantum physics and computer science! Quantum computing incorporates some of the most stunning ideas from 20th-century physics into an entirely new way of thinking about computation. Here,Chris Bernhardt offers an introduction to quantum computing that is accessible to anyone comfortable with high school mathematics. A mathematician himself, Bernhardt simplifies the mathematics and provides elementary examples that illustrate both how the math works and what it means.

Date: 11 July 2026 (Sat) Time: 16:00 - 19:30 \*HKT Coordinator: Alex Au **Light Refreshments & Pizza Night will be available!** **Please fill in the registration form at https://forms.gle/yrCHQKba1FKYmmJX8 for University Entrance QR Code.** LLM apps are easy to demo, but hard to debug. A chatbot gives a confident but wrong answer. A RAG pipeline retrieves the wrong context. An agent calls the right tool with the wrong argument. An evaluator says “pass”, but everyone in the room knows something is off. So where did things go wrong? In this HKPUG meetup, Tarun will introduce **Opik** and show how traces, spans, evaluations, datasets, and feedback loops can help developers debug LLM applications more systematically. After the talk, we will run a short mini workshop. Participants will inspect simplified Opik-style traces, discuss the clues, find the failing span, and decide what evaluation should be added to prevent the same issue from coming back. Finally, we will launch a **one-month Kaggle challenge** on the explanability of LLM using Opik! **Speaker** **Tarun Jain** Tarun is a Founding Engineer, and Content Creator at AI with Tarun. He is also a Google Developer Expert AI. He was a maintainer to open source AI projects like OpenAGI and BeyondLLM and has spoken at international conferences. Tarun enjoys building intelligent systems, knowledge graphs, and long term memory solutions for AI agents. Linkedin: [https://www.linkedin.com/in/jaintarun75/](https://www.linkedin.com/in/jaintarun75/) **What you will learn** * How to debug LLM apps beyond simply saying “the model is bad” * How traces and spans help reveal what happened inside a RAG or agent workflow * Common failure modes: bad retrieval, weak prompts, wrong tool calls, hallucination, evaluator bugs, and privacy/safety issues * How to turn bad answers into useful evaluation cases * How the mini workshop connects to the upcoming Kaggle-style challenge **Format** This meetup is part talk, part debugging game. Tarun will first introduce Opik and the core ideas behind LLM observability and evaluation. Then we will work through a few “broken bot” cases together. Each group will inspect the trace, identify the suspicious span, and explain what they think went wrong. No deep machine learning background is required. Curiosity and debugging instinct are enough. **Mini Workshop: Trace the Clue** Each group will receive a few simplified LLM application traces. For each trace, we will discuss: * What went wrong? * Which span looks suspicious? * Is it a retrieval issue, prompt issue, tool-call issue, hallucination, evaluator issue, or privacy/safety issue? * What evaluation or metric should be added? * Should this app pass or fail the release gate? The bad answer is the symptom. The trace is the evidence. Your job is to find what’s true. **Capacity:** 100 **Venue Info:** City University of Hong Kong, Kowloon Tong (Exact Location TBC) **Rundown:** **4:00–4:20 pm** — Arrival / registration / casual networking **4:20–4:30 pm** — HKPUG intro: tonight’s debugging case file **4:30–5:20 pm** — Talk: Debugging LLM Apps with Opik **5:20–5:35 pm** — Q&A **5:35–5:50 pm** — Short break **5:50–6:30 pm** — Mini workshop: trace the clue, find the failing span **6:30–6:55 pm** — Group discussion and case walkthrough **6:55–7:15 pm** — One-month Kaggle-style challenge launch **7:15 pm onwards** — Pizza, networking, and team forming **Audience pre-requisite:** * **Skills:** Recommended having basic level knowledge of Python **How to join?** 1.

**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.
