Where Are Operating Systems Headed?
An anonymous reader writes "Dr. Dobb's Michael Swaine breaks down the question of where operating systems are headed. Among his teasers: Is Vista the last version of desktop Windows? (Counterintuitively, he says no.); Did Linux miss its window on the desktop? (Maybe.) And, most interestingly, are OSes at this point no longer necessary? He calls out the Symbian smartphone OS as something to keep an eye on, and reassures us that Hollywood-style OSes are not in our short-term future. Where do you weigh in on the future of operating systems? In ten years will we all be running applications via the internet?"
Everybody is talking about running applications through the internet. Why would we, as consumers, want to do this? The RIAA and MPAA are attempting to limit our ability to make backups of things we purchase. Now, software appears to be heading in the same direction. If we start streaming applications, then we could easily get into a pay-as-you-use function, or some other horrid distribution system. Frankly, I would not want to be charged every time I open a text document, or an IM window, or an internet browser. And I don't like the idea of paying a subscription fee either. I think forcing people to stream applications through the internet will only push more people into using Linux, so that everything is right there on the machine.
The definition of an operating system I like to use is:
An OS is a collection of code that is used by software to manage access to system hardware via a well defined API, along with a collection of standardized utilities that provide for user access and management of system hardware and data structures and data streams associated with that hardware.
So, under this definition, the kernel is a peice of the OS, disk access utilities are part of the OS, but applets such as a mini word processor and paint program are mearly bundled utilities.
Two words: Consumer devices.
I think Steve Jobs has seen the future, and realised that the PC won't be so important, the action is all going to move to various types of devices aimed at consumers. So, he started with music players, is moving into portable video/gaming and now of course telephones, and has made the first steps towards TV. Television is the biggie of course, and I believe Jobs is being deliberately low key about his intentions there - with the low key announcement of the Apple TV box, for instance.
Here's a prediction, in the next few years Steve Jobs is going to make a presentation where he says something like "First we revolutionised the personal computer, then the music player and the telephone. Now we're going to revolutionise television..."
Until devices and other hardware components have enough built-in intelligence to communicate with each other and with user programs, and until their built-in intelligence is presented to applications through a standardized communications interface, there will always be a role for operating systems.
And the reason is simply that this is the primary role of an O/S: to glue together many rather dumb components (some virtual, some non-local), and to provide a standard abstraction for them, so that applications can be programmed with a degree of sanity. Everything that O/Ss do can be considered in those terms.
Host operating systems will disappear when they are no longer needed. And *that* will happen only when/if their key functions have migrated into the hardware, so it's a defensible argument to say that actually they will never really disappear, but transform.
