Open Source D System Software

"d-apt" is an APT repository to easily install/upgrade D binary packages on systems like Debian, Ubuntu, LinuxMint, etc.

Fsum Frontend is a files integrity checker. It can calculate 96 hash and checksum algorithms(CRC32, MD5, SHA1, SHA2, ADLER, DHA256, FORK256, ...). You can verify your files using a .sfv/.md5/.sha1/.sha2 file or create your own checksum file.

Anime checker is a portable tool that verifies the integrity of your files. It calculates the CRC32 of your files and compares it with the one found in the filename. Useful with fansubbed animes.

DNS zone file generator for Bind name server. It keeps fully customizable forward and reverse zones synchronized and reloads the server when necessary. Repository is on GitHub.

The DTraceToolkit is a collection of over 200 useful documented scripts for analysis of system and process behaviour. It allows in-depth inspection without disturbance of the system.

"gum" is an Open-Source file-archiving program, like GNU's "tar". The goal of this project is to create an easy-to-use, fast archiver that produces an output less than that of GNU's "tar".

The idea is to rewrite a good part of the Minix 3 OS from C to D, hopefully making the code easier to understand by grouping code in modules. Minix 3 web site: http://minix3.org/ D programming language: http://www.digitalmars.com/d/

N User is an user/group administration tool, using a ncurses interface. Its goal is to provide an user-friendly interface for users management without requiring an X server.

PowerNex is a microkernel operating system written entirely in the Nim programming language. Designed as a learning and research project, it explores OS development using a modern high-level systems language while still offering low-level control. PowerNex focuses on modularity, simplicity, and code clarity. While still in its early stages, the project includes basic kernel functionality, including memory management, task switching, and a custom bootloader, offering insight into building an OS from the ground up using newer programming paradigms.

REX: Remote EXecution Distributed Computing Services for Linux and Solaris, providing C and C++ APIs, librex library and "rexd" daemon software to implement Load Balancing Process Migration : Dump + Restore, Remote File and Resource Management.

Platform-independent recursive search library. C-API, written in C/C++, with mappings to C++, COM, D, Java, .NET, Python, Ruby, STL, with more to come.

This is the fifth or sixth generation of this idea, the big difference being that we have written some bootloader code and have started mapping out the kernel layout and structure. We have decided upon a core programming language for the kernel, and the core language for almost everything else. With a focus on isolating the MAJOR kernel features from the system itself, in what until now has remained research only instances, we hope to create a fully functioning exokerne. All code at this time will be available only via a git repository.

Voodoo Exchange Networking Library is a D library that provides a simple API for creating streaming, peer-to-peer TCP connections between two clients, even if they are behind NATs or firewalls, by attempting multiple NAT traversal algorithms.

s6-rc service definition directories debugger. Find loop in dependencies s6-rc services. Create visual form of dependencies of service definitions.
