Disko is a user interface application framework for the fast and simple development of flexible applications on embedded Linux systems, with a particular focus on interactive user interfaces. It is high-performance and easy to learn, and due to its architecture is well suited to creating complex applications.
BugOS is a microkernel operating system. It has a kernel, device drivers, a file system, and an Internet module. The main concepts are that every process has its own computer with its own console, security, and modularization. If a process wants to read the file, it asks the kernel. The kernel forwards the request to the filesystem driver, which reads and writes through the partition handler, which operates over the idehdd driver. The kernel is around 20 KB. Processes are fully separated from hardware.
