Hey everyone!
We are happy to announce that the fourth Hack&Roll 2026 pre-hackathon workshop is open for signups! 🎉
Note: signups are limited to Hack&Roll 2026 accepted/rejected participants only
Hackathon Mode: Going from 0 → 1 in 24 Hours with Codex
by OpenAI
This hands-on hackathon workshop introduces Codex, OpenAI’s coding agent, to help you go from idea to working demo—fast. You’ll learn how to build in hackathon mode using Skills, Model Context Protocols (MCPs), and the Responses API’s built-in tools to give your agent structure, capabilities, and real-world context. We’ll show how Codex fits seamlessly into your workflow—via the CLI, IDE, cloud, or even on mobile—and share practical strategies for scoping, iterating, and shipping under tight time pressure. We’ll wrap up with live demos—plus a chance to take home some swag.
📅 Friday, 9th January 2026, 5:00 to 7:00pm SGT
📍 NUS COM3-01-23, Seminar Room 14
🍕 Refreshments will be provided after the workshop

Our 8th and final workshop of Hack&Roll 2026 is open for registration!
Multi-Platform Programs in C++
By QRT
C++ code that runs correctly on one operating system may fail or behave differently on another. This talk explores the practical challenges of writing multi-platform C++ programs and how to handle platform-specific behavior in a controlled and predictable way.
We’ll discuss common cross-platform pitfalls, why they occur, and how to use conditional compilation (#if defined(...)) to support different operating systems within the same codebase.
The session includes a short hands-on activity where participants build a small, working C++ program designed with portability in mind. Along the way, the talk also includes general programming and development tips aimed at helping participants write more robust and demo-ready software.
Pre-requisites
Make sure the following software is installed on your system before the workshop based on your operating system:
Windows
- Mingw64 GCC
- WSL (Windows Subsystem for Linux)
- espeak. Download the version that says "Compiled for Windows"
Linux
- espeak. Download the version that says "compiled for Linux 32bits"
MacOS
- Ensure that say is installed: Open Terminal > type say something and you should hear the word "something".
