- Problems with legacy code are caused by design faults - see MS-DOS. UNIX was
- designed flexible enough to allow replacement of key parts without breaking
- all existing software. Relying on having everything in C-source does make such
- things easier though :).
-
- Security is a problem mostly because of the way the internet has evolved. Much
- of the security stuff depends on the ability to trust another host. This made
- sense in an environment were access to networked machines and communication
- lines was tightly controlled. Today anybody can buy a computer, hook it up
- to the Internet and start attacking other machines while having root privilege
- on his own. This situation requires new approaches (like firewalling and
- end-to-end encryption). Still UNIX is a decent platform to develop these new
- things on.
-
- UNIX was not designed for use in a hostile environment and still does remarkably
- well for the amount of networking features and services it offers. If you
- take the time to trim down the list of offered services and disable or
- replace all stuff that is insecure because it is so convenient or really badly
- designed (like sendmail), you'll be pretty safe. Remember that every operating
- system has bugs that can be exploited. By definition, the only secure computer
- is the one locked in a safe, without connections to the outside, powered off.

- I do write software and to me UNIX (including vi) is the nicest environment for
- programming I have seen so far. It is incredibly powerful and flexible and
- almost impossible to crash while writing application software. Most parts of it
- definitely were written by programmers for programmers.

- A lot of work is in progress to make the the kernal more modular and easier
- to maintain. The resulting operating systems will still have the UNIX API
- wether they are called UNIX or not. The decisions of how many wheels in what
- arrangement you need to make a good car has been done a long time ago. Whereas
- the leading desktop operating system is still a Dinosaur precariosly balanced
- on a kid's tricycle. In their latest offering, MS went through some lengths to
- camouflage the tricycle, but it is still there :).

- Probably not. The basic UNIX API is not broken and thus unlikely to go away.
- The problem with MS-DOS is that it is just a glorified bootstrap loader
- offering only a fraction of the services you would expect from an operating
- system. The abstraction layer between hardware an application is missing,
- and that is what built the compatibility trap.

- Not unless you come up with a truly new and revolutionary concept for
- an operating system. I might have overlooked some recent developments
- though (not that I would monitor this field too closely anyway :) )
- Most currently hyped operating systems are still trying to reach the
- level of functionality UNIX has been offering for the past ten years.
- UNIX will be phased out if people come up with something that does the
- job better. I can wait for that day.

- Just my DM 0,02 of opinion...
