OSNews, Generic OSes

We report regularly about Visopsys - one of the few hobby operating systems that survived where virtually all the others (SkyOS, Syllable, etc.) died out. They've got a new website, which seems like a nice occasion to give it some attention again.

The bulk of Visopsys is a fully multitasking, 100% protected mode, virtual-memory, massively-monolithic-style kernel. Added to this is a bare-bones C library and a minimal suite of applications - together comprising a small but reasonably functional operating system which can operate natively in either graphical or text modes. Though it's been in continuous development for a number of years, realistically the target audience remains limited to operating system enthusiasts, students, and assorted other sensation seekers.

Member since:

an OS is way way way way more difficult than a vehicle.
13 millions lines of Code for Linux, thousands of devices and drivers, hundreds of badly designed hw but obliged to support, hardware itself moving so so fast into new architectures (HSA ?), ...

The golden days when someone could stay few weeks in his room them come out with an OS are over.

I have to disagree on both points:

1) 'OS is more difficult that vehicle', no, some OS are simple, some vehicles are simple, some OS are complicated, some vehicles are complicated. Generally, they're as complicated as you want to make them.

2) The days of making an OS in a couple of weeks are over? No, only if you want to consider an OS to be what the big players want you to think it is. An OS does not need to have thousands of drivers to be useful, only to support thousands of different types of hardware. Target specific hardware, don't overcomplicate, and making an OS is as simple (or as hard!) as it ever was.
