Userful Desktop is a locked-down and secure desktop Linux distribution designed for schools, libraries, kiosks, Internet cafes, digital signage, and public access computers. Customization and control is all done through the cloud: a simple and intuitive administration Web site. The "Userful MultiSeat" desktop virtualization software that supports Ethernet and USB connected zero clients is also included. Desktop settings can be managed for thousands of desktops at once via session profiles, which are created and stored in the cloud. Key features include time management, print cost recovery, Internet filtering, privacy protection, automated clean-up, remote desktop monitoring and control, prepaid cards, and automatic updates. It replaces both DiscoverStation and Desktop Server.
Kevux is an operating system based mainly on GNU operating programs and a Linux kernel, all compiled with uclibc instead of the more common glibc. It is not FHS or LSB compatible. Compared to other Linux distributions, Kevux is space efficient (making it suitable for USB disk operation) and difficult to hack into.
UNIXem is a small and simple library that provides emulation of several popular Unix API functions on the Win32 platform. Its primary purpose is to assist Win32 programmers who are porting to Unix or are writing multi-platform code. API functions include opendir/readdir/closedir, glob/globfree, readv/writev, pathconf/realpath, mmap/munmap/msync, dlopen/dlclose/dlsym/dlerror, gettimeofday, and getpagesize.
Buenos is a small SMP operating system skeleton that can be used as a base for operating systems project courses. The system is intended to be used as OS project base code which students can improve. Extensive documentation with suggestions for assignments or exercises is included with the system. It runs in a machine simulator called YAMS, which is its sister project.
JayOS is a live CD Linux distribution intended for use as a more secure mobile environment. It uses GNU makefiles and Bash shell scripts to automate the building of a complete Linux distribution from source. The result is a turnkey solution for creating a compact, highly-customizable OS. JayOS includes many standard network security and filesystem tools, a full-blown development environment, and many programming tools and libraries including GCC, GDB, DDD, Perl, GTK+, Tcl/Tk, PHP, Ruby, Python, Qt, and Glade. It runs well on commodity hardware, and can be configured to run entirely from memory. In-RAM filesystem encryption with plausible deniability provides a more secure mobile workstation. It is based on Linux From Scratch.
Recovery Is Possible (RIP) is a CD or USB boot/rescue/backup/maintenance system. It has support for many filesystem types (Reiserfs, Btrfs, Ext2/3/4, HFS+, ISO-9660, Squashfs, UDF, XFS, JFS, UFS2, CIFS, MS DOS, NTFS, and VFAT) and contains several utilities for system recovery. It also has IDE/SCSI/SATA, RAID, LVM2, and Ethernet/Wireless network support.
uClibc (µClibc) is a C library for developing embedded Linux systems. It is much smaller then the GNU C Library, but nearly all applications supported by glibc also work perfectly with uClibc. Porting applications from glibc to uClibc typically involves just recompiling the source code. uClibc even supports shared libraries and threading. It currently runs on standard Linux and MMU-less Linux (also known as µClinux) systems with support for ARM, i386, h8300, m68k, MIPS, mipsel, PowerPC, SH, SPARC, and v850 processors.
Grml is a live system (live CD) based on Debian. It includes a collection of GNU/Linux software especially for system administrators and users of texttools. It provides automatic hardware detection and its default shell is the zsh. You can use it e.g. as a rescue system, for analyzing systems/networks, or as a working environment. It is not necessary to install anything to a hard disk; you don't even need a hard disk to run it. Due to on-the-fly decompression, it includes more than 2 GB of software and documentation on the CD.
