Linux Kernel
Linux Kernel source tree
The Linux Kernel is the core component of the Linux operating system—a free, open-source, monolithic, Unix-like system kernel initiated by Linus Torvalds in 1991 and since evolved into a foundational technology powering everything from servers and supercomputers to smartphones and embedded devices. There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Extensive filesystem compatibility (ext4, Btrfs, FUSE, XFS, etc.) Broad... -

Zen Kernel
Zen Patched Kernel Sources
Zen Patched Kernel Sources. This is the top level of the kernel’s documentation tree. Kernel documentation, like the kernel itself, is very much a work in progress; that is especially true as we work to integrate our many scattered documents into a coherent whole. ARC processors are highly configurable and several configurable options are supported in Linux. Some options are transparent to software (i.e cache geometries, some can be detected at runtime and configured and used accordingly, while some need to be explicitly selected or configured in the kernel’s configuration utility. -

Shapes
Graphical programming. Includes n-dimensional sorting.
Write programs as graphical dataflow charts instead of text. Compile them to any programming language you want. Besides this project includes the most efficient tree-based sorting algorithm that is possible. Originally developed on a CTOS Color NGEN, at first in Pascal, later ported to C, finally - 20 years later - ported to Linux. Currently it's still not really system independent. But it's intended that further releases will cure this. -

nnn
The missing terminal file browser for X
nnn is a fork of noice, a blazing-fast lightweight terminal file browser with easy keyboard shortcuts for navigation, opening files and running tasks. noice is developed considering terminal based systems. There is no config file and mime associations are hard-coded. However, the incredible user-friendliness and speed make it a perfect candidate for modern distros. nnn works with the desktop opener, adds new navigation options, navigate-as-you-type mode, enhanced DE integration,... -

MooseFS
Fault tolerant, POSIX-compliant, Net Distributed Storage / File System
...It spreads data over several physical servers which are visible to the user as one resource. For standard file operations MooseFS mounted with FUSE acts as other Unix-alike file systems: * A hierarchical structure (directory tree) * Stores POSIX file attributes (permissions, last access and modification times) Supports special files (block and character devices, pipes and sockets) * Symbolic links (file names pointing to target files, not necessarily on MooseFS) and hard links (different names of files which refer to the same data on MooseFS) * Access to the file system can be limited based on IP address and/or password MooseFS on GitHub: https://github.com/moosefs/moosefs Packages repository, download: https://moosefs.com/download Documentation: https://moosefs.com/support Recent changes: https://github.com/moosefs/moosefs/blob/master/NEWS -

DECO for minix3 book ISO
minix3 DECO file system browser for book_ISO_3_1_0
default book_ISO_3_1_0 + the DECO minix pack: you no need more software to run the DECO there is /bin dir, type "make install" to install precompiled for book_ISO_3_1_0 DECO binary and data files DECO has enough power to walk MINIX directory tree in place of "emergency browser" so DECO binary image can be also linked into /bin directory -

openPOWERLINK
An Open Source POWERLINK Stack
openPOWERLINK is an Open Source Industrial Ethernet stack for communication in hard real-time. It can be operated as both, Managing Node (master) and Controlled Node (slave). With version 2.0, the source code has been cleanly split into an application-oriented user library and a time-critical stack driver. The latter may be moved to a dedicated communication processor or into a kernel module to deliver enhanced performance while still keeping the API in user space. A full documentation... -

motion5
Specialised variant of GRBL focused on motion of up to five axes
...Wherever usage and handling of motion5 is different to original GRBL, this is described in Wiki. For the G-code commands please note that motion5 supports more axes which are named "A" and "B". So a GRBL-command "G1X10.0Y20.0Z10.0" which moves its three axes would be e.g. "G1X10.0Y20.0Z10.0A20.0B30.0" in motion5 to move all five axes. -

CTREE Graphic Tree Generator for C
An analysis tool showing the structure of a C program
CTREE is a command line utility providing analysis tools useful to software engineers tasked with tracking down problems or verifying a program's soundness. It is also an aid to understanding the structure of unfamiliar programs. As it works with standard C it finds most of its utility in embedded systems and older software. CTREE comes with a comprehensive manual. CTREE is is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative... -

AEBL
AEBL is a mobile media distribution system
...It currently is designed to run on a raspberry Pi, although it is being ported to other systems. The AEBL blog is located here: http://aeblm2.blogspot.ca/ For those interested in trying it out, you will need a Raspberry Pi (should be the B series with 512MB) and a SD card (4GB or higher, recommend base 8GB but the larger, the better, for content storage). The current image is a ~680MB 7zip compressed file of it's original 2.7GB size, located on dropbox, here: https://www.dropbox.com/s/lj0r6yia4tsnz8w/140815-aeblpi.img.7z?dl=0 -

MSX Disk Interface Emulator
A Interface to adapt modern SD Card to the old MSX computers
This is an open source project that aims to create a MSX cartridge that acts as a old disk drive interface but in fact it will be accesing a modern SD Card. For the MSX it will be as if there is a magnetic disk drive with a real magnetic disk but for real it will be accessing a .dsk file inside a sdcard. Development tools used are: - Kicad version 2013-07-07 - Microchip XC8 v1.21 (free mode) - Micrchip MPLAB X IDE v1.90 - Altera´s Quartus Web Edition 11.0 UPDATE... -

NetFireCoRE
Network Firewall Linux Kernel Module with Conflict Resolution Engine
We implement an open source conflict resolution framework that consists of a user-space C application that automatically resolves firewall rules anomalies, and b) a generic tree (called policy tree), implemented as a Linux kernel module which maintains the resolved firewall rules and enables the necessary hooks to netfilter for matching incoming (or outgoing) network packets. Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or nftable maps), especially for large systems with a huge number of rules. ... -
