Assembly programming is an educational repository that introduces assembly programming for the x86-64 architecture on GNU Linux systems. The project is structured as a series of explanatory blog-style lessons that guide readers through the fundamentals of low-level programming. Topics include processor architecture basics, writing and building assembly programs, memory layout concepts such as stack and heap, and interaction with the operating system through system calls. The material is...

...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.

gVisor is an application kernel developed by Google that provides a strong layer of isolation between applications and the host operating system. Written in Go, it implements a Linux-compatible system call interface that runs entirely in user space, creating a secure sandboxed environment for containers. 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. ...

A multi-threaded-style OS for the Spectrum +3. Based on a kernel/userland model, it decouples the kernel implementation from the run-time system call mechanism, and provides for some POSIX-style functions. A file descriptors layer provides abstraction for easy file redirection. Userland processes are relocatable, and have no knowledge of the kernel or memory layout, leaving the flexibility to change the memory paging model without requiring a recompile of all userland programs.

DosMenu v30 ==================================== Complete rewrite using watcom and dos4/gw. DMenu is a small graphical menu program. It is no longer limited in entry count. To create a menu, call "menugen.exe". Update v3.0: Added scrolling For most games and programs, you will have to create a batch file to cd into their install directories. Example: set2.bat -------- cd c:\settlers s2.exe cd c:\dmenu\ To start, please run main.exe IMPORTANT: don't forget to cd back from your game directory in your batch files to the DMenu directory, so the skin file will be found and all paths are correct. ...

An ambitious project designed to workaround many of the limitations of conventional web and database services. Fast lightweight database-web server primarily targeting virtual environments. Run up to ten or twenty times more independent virtual guests per hypervisor than Linux or Windows Secure, isolated, non-extensible API is opaque to hackers.

Akalon is a Bare-Bones Embedded RTOS that's designed to be simple and portable to any Microprocessor or System (Board). Currently supports the Intel and ARM Architectures.

A real time OS based on uITRON 4.0 full specification. You can use dynamic objects and easy to use. This is suitable for 16bit-CPU, even. First target is H8/300H (AKIZUKI AE-H8/3069-LAN). About the ITRON specification: http://www.assoc.tron.org

Implementation of virtual threads for the XS-1. Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.

API Caller is a software for extracting API functions from any executable and can be used to call them. With this tool, quality can easily be checked by calling functions and checking them if they are error-free.

...It is ideal starting point to learn about operating systems. The main goal of the project is to provide a network kernel fully compatible with the Linux Kernel in the system call layer

The dude is a UNIX debugging package independent of the ptrace() system call; it consists of a kernel module [the_dude.o], a library to interface with the module [libduderino.so], and an ncurses client [ddbg] .

The goal of the Stik's Security Module project is to provide a vehicle for implementation of a label based security policy complimentary to the existing Linux security model. The module is implemented by hooking the Linux 2.4.x system call table.

MSP430static is a tool for the analysis of MSP430 firmware images, such as those produced by TinyOS and mspgcc. Features include call-graph generation, recovery of library symbol names, and easy extensibility in Perl or SQL.
