Whatever happened to the Hurd? – The story of the GNU OS

Filed under
OS

Although the GNU operating system was first conceived in 1983 and the Free Software Foundation (FSF) had first declared an interest in using the Mach microkernel as the core of the GNU operating system kernel as far back as 1987, the sources of the Mach microkernel – developed at Carnegie Mellon University (CMU) – weren’t released under a suitable licence until 1991, by which time Linus Torvalds had begun his project to write a UNIX-like kernel for the IBM 386.

If the Linux kernel hadn’t been written when it was, licensed under the GPLv2 and surrounded by components of the GNU operating system, or Linux hadn’t captured the moment and the imagination of developers, the energy that gathered around Linux might have gone to the Hurd and the world might have been a different place.

Some Fresh I/O Scheduler Benchmarks: Linux 4.13 With BFQ, CFQ, Kyber, Deadline

For those curious about the state of I/O schedulers with the in-development Linux 4.13 kernel, here are some fresh disk benchmarks using the 4.13 Git kernel on an Intel laptop/ultrabook and testing the various in-kernel options. Tests were done from a Broadwell era Lenovo ThinkPad X1 Carbon with SSD. In the days ahead I'll have some tests as well from a slower, rotational media system. Read more
