Redox is an operating system written in Rust, a language with focus on safety and high performance. Redox, following the microkernel design, aims to be secure, usable, and free. Redox is inspired by previous kernels and operating systems, such as SeL4, MINIX, Plan 9, and BSD.
Redox is not just a kernel, it's a full-featured Operating System, providing packages (memory allocator, file system, display manager, core utilities, etc.) that together make up a functional and convenient operating system. You can loosely think of it as the GNU or BSD ecosystem, but in a memory safe language and with modern technology. See this list for overview of the ecosystem.

2) something like the ``everything is a file'' logic of Plan9 except with URL's and less needlessly elitist.
Thompson. The one thing I stole was the hierarchical file system because it was a really good idea—the difference being that Multics was a virtual memory system and these "files" weren't files but naming conventions for segments. After you walk one of these hierarchical name spaces, which were tacked onto the side and weren't really part of the system, you touch it and it would be part of your address space and then you use machine instructions to store the data in that segment. I just plain lifted this.
By the same token, Multics was a virtual memory system with page faults, and it didn't differentiate between data and programs. You'd jump to a segment as it was faulted in, whether it was faulted in as data or instructions. There were no files to read or write—nothing you could remote—which I thought was a bad idea. This huge virtual memory space was the unifying concept behind Multics—and it had to be tried in an era when everyone was looking for the grand unification theory of programming—but I thought it was a big mistake.
Who but Satan would be able to create ed or dc?You best be joking. Is it opposite day on /prog/?
5. A regular expression enclosed in slashes `/' addresses
the line found by searching forward from the current
line and stopping at the first line containing a string
that matches the regular expression. If necessary the
search wraps around to the beginning of the buffer.
6. A regular expression enclosed in queries `?' addresses
the line found by searching backward from the current
line and stopping at the first line containing a string
that matches the regular expression. If necessary the
search wraps around to the end of the buffer.
Addresses are separated from each other typically by a comma
`,'. They may also be separated by a semicolon `;'. In
this case the current line `.' is set to the previous
address before the next address is interpreted. This fea-
ture can be used to determine the starting line for forward
and backward searches (`/', `?'). The second address of any
(1, $)w filename
The write command writes the addressed lines onto the
given file. If the file does not exist, it is created
mode 666 (readable and writable by everyone). The file
name is remembered if there was no remembered file name
already. If no file name is given, the remembered file
name, if any, is used (see e and f commands). `.' is
unchanged. If the command is successful, the number of
characters written is printed.
DIAGNOSTICS
`?name' for inaccessible file; `?' for errors in commands;
`?TMP' for temporary file overflow.
BUGS
The l command mishandles DEL.
A ! command cannot be subject to a g command.
Because 0 is an illegal address for a w command, it is not
possible to create an empty file with ed.
