When learning statistics, one of the most fundamental yet usually grossed over concepts is that of **variance** (i.e. the square of the standard deviation in normal distribution). As we know, virtually all statistical operations which measure deviations of individual values from the norm involve adding the **SQUARED differences between the two numbers**. However, very few instructors could explain why we have to use squares rather than just the absolute values of the difference (or other even powers such as 4, if the intention is to avoid the negatives). This tutorial shall cover this in a convincing manner. Secondly, while we all know the variance of a SAMPLE is arrived by dividing (n-1) of the sum of squared differences, where n is the number of observations, few can articulate the rationale behind it. This tutorial shall also prove step by step why this is case, so after this you could appreciate the logic behind this ingenious insight instead of just reciting it like a medieval myth.

Date: 30 May 2026 (Sat) Time: 15:30 - 18:00 \*HKT Coordinator: Ming Tou, Alex Au Light Refreshments will be available! This is a **workshop** for Python Data Cleaning. Please bring along your laptop with **Python3 installed with enough battery**! *Winners will get a small prize as an accomplishment **in the next meetup**.* Please fill in the form for admission: https://forms.gle/MGMGFiMZQGY4CZuP7 ***Mind the Data Gap*** **This model will be delayed due to: missing values, outliers, and delimiter congestion.** In this hands-on HKPUG workshop, we are turning a Python data cleaning exercise into a gamified team sprint. You will work with a **synthetic Hong Kong-inspired transport dataset**. The data is messy on purpose: missing values, weird outliers, inconsistent categories, URL-encoded station names, confusing delimiters, and fields that look useless until you extract the hidden signal. Your mission is simple: **Clean the data. Extract better features. Run the scorer. Beat the model.** You do not need to tune the model. You need to **rescue the data**. ***How the Challenge Works*** Teams will write a Python data transformation script to clean and enrich the dataset. Our scoring pipeline will then: 1. Run your transformation on the training and test data 2. Remove any label / target leakage columns 3. Train a fixed Gradient Boosting model 4. Evaluate the model using proxy metrics such as F1 and ROC-AUC 5. Convert the result into a data cleaning score This is not meant to be a perfect data quality metric. It is an accessible proxy: if your **cleaning** and **feature extraction** help the **model perform better**, your team gets a better score. **Capacity:** 60 (Team of 4) **Venue Info:** City University of Hong Kong, Kowloon Tong (Exact Location TBC) **Rundown:** **30th May** **15:30 – 15:40** Opening Remarks, Team Formation & GitHub Setup **15:40 – 15:55** Briefing: Data Traffic Report, Challenge Rules & Scoring Pipeline **15:55 – 16:20** Demo: Messy Dataset, Data Cleaning Strategy & `transform.py` **16:20 – 17:10** Team Sprint Part 1: Missing Values, Outliers & Category Cleanup **17:10 – 18:00** Team Sprint Part 2: Feature Extraction, Hidden Signals & Scoring Iterations **18:00 -** Networking outside City University **13th June** **\- 23:59** Winner Team Announcement **Audience pre-requisite:** * **Hardware:** **MUST** bring a laptop with Python 3 installed and a code editor (VS Code, PyCharm, etc.). * **Skills:** Recommended having basic to intermediate-level knowledge of Python (handling JSON, using the `requests` library, and writing basic `if/else/while` loops). **How to join?** 1.

Join us for a premier technical gathering where the AWS User Group Hong Kong (AWS UGHK), KSUG.AI (KubeSmart & AI User Group), and the Hong Kong Cloud Developers Association (HKCDA) converge for a deep dive into the future of cloud-native infrastructure. As Kubernetes becomes the bedrock for modern AI/ML workloads, this "Kubernetes Night" is designed to bridge the gap between robust infrastructure and intelligent applications. We will explore real-world orchestration challenges on AWS, the integration of AI within Kubernetes clusters, and the evolving cloud developer ecosystem in Hong Kong. Whether you are a DevOps engineer, a Cloud Architect, or an AI developer, this night is dedicated to sharing "battle-tested" insights and fostering community innovation. Target Audience: DevOps Engineers, SREs, AI Engineers, Cloud Architects, and Cloud Developers. Co-Organized by: AWS UG x KSUG.AI x HKCDA OC Members: Alex Lau (AWS UG Lead), Leonardo LEE (KSUG.AI / HKCDA organizer) — Key Benefits of Attending — 1\. Cross\-Community Synergies — Gain access to three distinct talent pools in one room\. From AWS\-specialized builders and KSUG's Kubernetes/AI experts to the broad developer advocacy of HKCDA\, you will experience a 360\-degree view of the cloud landscape\. 2\. Deep Technical Knowledge \(K8s \+ AI\) — Understand how to optimize Kubernetes for AI/ML workloads\. Learn about managing GPU resources\, scaling inference engines\, and utilizing AWS\-native services like EKS to power the next generation of smart applications\. 3\. Direct Networking with Local Leaders — Connect with the Executive Committees and Organizers of all three groups\. An unparalleled opportunity to find mentors\, career opportunities\, or collaborators for your next big project within the Hong Kong tech ecosystem\. 4\. Stay Ahead of Cloud Trends — Get first\-hand updates on the latest CNCF landscape shifts and AWS innovations\. We move beyond marketing slides to discuss technical implementation\, cost optimization \(FinOps\)\, and security best practices\. 5\. Professional Development & Giveaways — Expect "Quiz Time" sessions with opportunities to win exclusive swags and professional certification discounts \(e\.g\.\, Linux Foundation/CNCF exam vouchers\)\. — Agenda — 18:45 – 19:00 · Registration / Check-in / Setup 19:00 – 19:05 · AWS UG Introduction — Alex Lau 19:05 – 19:15 · KSUG.AI and HKCDA Introduction — Leonardo LEE 19:15 – 19:45 · Vibe-Coding an Internal PaaS on K8s in a Week — Yinyin Chiu (Oursky) 19:45 – 20:00 · Group Photo & Short Break 20:00 – 20:20 · Basic Security & AI Considerations on K8s — Bill Ho (Veeam) 20:20 – 20:50 · Achieving CKA Certification: Key Requirements for Kubernetes Administrators — Simon Sung (Kenfil) 20:50 – 21:10 · Special Guest Sharing 21:10 – 22:00 · Networking 22:00 · End — Topic Details — "Vibe-Coding an Internal PaaS on K8s in a Week" — Yinyin Chiu, Developer, Oursky Limited AI agents turned every non-dev into a shipper of internal tools — but non-devs can't deploy on K8s, and deploying internal tools on public PaaS poses risk. So we gave ourselves 7 days to build SkyRocket: a self-hosted PaaS on our own K8s, gated behind Tailscale. "Achieving CKA Certification" — Simon Sung, Kenfil Simon is a highly accomplished professional with over 24 years of experience in I.T. consulting, recognized for expertise in server-side systems specializing in Kubernetes Cloud Native and VMware virtualization.

Session Abstract ### SQL Server 2025: The Developer’s Revolution Explore SQL Server 2025’s new dev features -JSON type, Regular Expressions, and Change Event Streaming for real-time pipelines. See how REST API and Data API Builder turn your data into secure, high-performance APIs. Packed with demos, this session is perfect for developers, DBAs, and architects \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
