Visopsys is a hobby OS for x86-compatible PCs, started in 1997. Version 0.9 was released this morning, and there’s a change log. The summary:
This major release offers a subtly updated look, enhanced networking capabilities and associated programs, Unicode support, a software packaging/download/install/uninstall infrastructure with an online ‘store’, a user space window shell, VMware mouse integration, HTTP, XML, and HTML libraries, some C++ and POSIX threads (pthreads) support, ‘pipes’ for interprocess communication, and additional hashing algorithms.
Visopsys has a long history on OSNews – the oldest mention being from 2005. It’s been in relatively steady development ever since.
I really miss the days where OS’es were competitive. Now we have Linux omnipresent in everywhere (including Windows!), and there is little need to try anything else. Even low power devices themselves became very powerful to run full fledged operating systems (again Linux distributions), so there is little need to try anything else.
On my Raspberry Pi (which is the slowest device I have), I tried RISC OS, but quickly went back to Raspian (And it looks like the download is no longer listed): https://www.raspberrypi.org/downloads/
On the router I have UniFi (which is Linux, and allows SSHing into the actual hardware). I used to have pfSense based on FreeBSD., though. Speaking of which, there are still BSD bases systems (Mac OS, PlayStation OS, FreeNAS), but even that is becoming rare.
I remember playing with bootloaders, and writing my tiny kernel and drivers. However I do not foresee being able to go down to that level again. The game is unfortunately already lost, and in a way I don’t feel sad about it for some reason…
