Capslock is a command-line tool for analyzing the capabilities of Go packages to reveal what privileged operations their code and dependencies can perform. Rather than detecting vulnerabilities, Capslock focuses on identifying capabilities — permissions implied by calls to sensitive or privileged standard library functions, such as file system access, networking, or process control. By following transitive call graphs, it classifies which security-sensitive operations each package can reach,...

operating_system_guide is a curated, beginner-friendly resource aimed at helping aspiring developers learn how to create an operating system from scratch. Maintained by AzkaDev, the guide collects educational materials, links, and code snippets that walk learners through each major component of OS development—from bootloaders to kernel structures and system calls. While still evolving, the guide acts as a roadmap and inspiration hub for those wanting to explore low-level systems programming...

...Unlike traditional virtual machines or lightweight syscall filters, gVisor follows a third approach that offers many of the security benefits of virtualization while maintaining the speed, resource efficiency, and flexibility of containers. Its key runtime, runsc, integrates seamlessly with container ecosystems such as Docker and Kubernetes, making it easy to deploy sandboxed workloads using familiar tools. By intercepting and safely handling syscalls from applications, gVisor reduces the attack surface of the host kernel, mitigating risks associated with running untrusted or potentially malicious code in containerized environments.

...HelenOS does not aim to be a clone of any existing operating system and trades compatibility with legacy APIs for cleaner design. Most of HelenOS components have been made to order specifically for HelenOS so that its essential parts can stay free of adaptation layers, glue code, franken-components and the maintenance burden incurred by them.

Note: I haven't even looked at this project for years. I was a pretty bad programmer back then, so the code is sloppy. The next version will be better. Similar to a stream cipher, but rather than performing an exclusive OR on the input bytes and cipher, it performs a mixture of 'rolling' (see x86 instruction ROR) and bit NOT operations according to the key.
