BoringSSL is a Google-maintained fork of OpenSSL, designed specifically to meet the security, performance, and maintainability needs of Google’s infrastructure and products. While fully open source, BoringSSL is not intended for general public use — it serves as a streamlined, heavily modified SSL/TLS and cryptography library optimized for Google’s internal ecosystem, including Chrome/Chromium, Android, and other Google services. The project prioritizes security, simplicity, and maintainability over backward compatibility. Unlike OpenSSL, BoringSSL provides no guarantee of stable APIs or ABIs, meaning third-party projects depending on it may frequently break. Google products that use BoringSSL ship their own copies and update them as needed, enabling faster iteration without legacy constraints. BoringSSL includes comprehensive API documentation, build instructions, and guidance for porting code from OpenSSL.

os-tutorial is an open source educational project by cfenollosa that teaches the basics of building an operating system from scratch. The repository provides step-by-step lessons starting with bootloaders and moving through kernel development, interrupts, memory management, and system calls. Each tutorial is accompanied by clear explanations, code examples, and references to deepen understanding. The project uses x86 assembly and C to illustrate concepts, making it accessible to students and hobbyists interested in low-level programming. By compiling and running the examples with tools like QEMU, learners gain hands-on experience with OS fundamentals. With its structured lessons and approachable explanations, the repository has become a widely recommended resource for operating system beginners.

BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners.

A port of the Linux operating system kernel and assorted GNU userspace to the GameCube and Wii gaming consoles from Nintendo. Please, see http://www.gc-linux.org for additional information.

This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the Linux kernel. The repository is structured so that every lesson corresponds to a snapshot of the source code at that stage, making it easier for learners to follow the progression of kernel development. The design of the lessons emphasizes gradual learning, allowing readers without prior OS development experience to understand kernel internals. The project is still under active development and encourages community contributions to expand its lessons and improve its content.

Spleen started as a personal challenge. Patrick Wildt (patrick@) recently imported ssdfb(4), a driver for small OLED displays in OpenBSD and needed a 5x8 font to be able to squeeze more columns and rows on those devices. As someone spending most of his time in a terminal, I have been thinking about drawing my own font for a while, and this was the perfect opportunity. To be able to test character spacing and alignment, I started to use the font in xterm, then a zoomed version, and one thing leading to another, I started creating a 8x16 version, and then bigger versions based on it. Spleen is now available in 5 sizes: 5x8, 8x16, 12x24, 16x32, and 32x64. Fonts are provided in the Glyph Bitmap Distribution Format (BDF), and in the .dfont format for Macintosh users. All sizes contain all ISO/IEC 8859-1 characters, except for the 5x8 version which only contains printable ASCII characters.

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, giving developers visibility into what their dependencies are capable of doing. This helps apply the Principle of Least Privilege to Go software, guiding audits, supply chain reviews, and trust assessments. Capslock aims to make security posture analysis more proactive by surfacing capability-based risk signals before malicious or overly powerful code is introduced into production.

A portable version of the ARJ archiver, available for a growing number of DOS-like and UNIX-like platforms on a variety of architectures.

ALL FILES FOUND HERE ARE _OLD_, PLEASE MOVE TO https://ezquake.github.io FOR THE LATEST VERSIONS Combining the features of all modern QuakeWorld® clients, ezQuake makes QuakeWorld® easier to start and play. The immortal first person shooter Quake® in the brand new skin with superb graphics and extremely fast gameplay. The project started in August 2004 as a derivate of the FuhQuake client by fuh which is a derivate of ZQuake QuakeWorld client by Tonik, one of the current ezQuake developers. Finally, ZQuake is a derivate of QuakeWorld client made by Id Software. This company has created the Quake game itself and later on released the source codes of game executables under GNU General Public License. Because id Software didn't release the whole game for free to the public you still need some of the original files from Quake to play QuakeWorld using our client.
