Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Step by step guide: How to install Microsoft Office in any Linux distribution

There are multiple options how to install MS Office on Linux.

VM-based - Integrate Windows apps running in a Windows virtual machine as native-looking in Linux

LinOffice - Microsoft Office Launcher for Linux, my own fork of Winapps which is focused on only running Microsoft Office, with some Office-specific improvements over Winapps and a fully automated setup. Eventually I would like to create a GUI for it. Decribed below
Winapps, based on KVM, QEMU, Docker/Podman and FreeRDP. Still actively maintained (getting Github commits). Decribed below
Cassowary, based on KVM, QEMU, libvirt/virt-manager, and FreeRDP. Last release in Feb 2022 and seems to be abandoned.

WRITEUP.md

The following is a write up for after a series of several vulnerabilities found in the Hack Club Clubs Dashboard. These vulnerabilities were found on October 23rd 2025.

Background

I was looking through the Hack Clubs Club Dashboard code after reading a wonderful writeup of another vuln for Clubs by @NeonGamerBot-QK. I noticed that all the code was in a singular 16000+ line main.py file, so I looked through this and found several vulnerabilities.

Hack Club has a amazing security program lead by 3kh0. This allows teenagers to earn money for security vulnerabilities they find in Hack Club code. The vulnerabilities found were reported through the Hack Club Security program.
