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".
📅Thursday, 15th January 2026, 5pm to 7pm
📍 NUS COM3-01-21 Seminar Room 12

Hackerschool Week 4: Intro to Shell & Vim
🗓️ Tuesday, 3 February 6.30pm
📍 SR13 @ COM3-01-22
🧁 Refreshments will be served!
Shell and Vim are two essential tools for working efficiently in a Unix-based environment (and both are commonly encountered by 2030s students!)
We’ll start with an introduction to the shell, covering basic navigation, file management, and common commands to help you get comfortable working in a terminal.
After that, we’ll move on to an introduction to Vim, where you’ll learn core concepts, essential keybindings, and tips to make editing code and text less intimidating (and more productive).
Beginners welcome!
