- for the developer, lack of memory protection is a pain. but how many
- Unix clones can handle realtime tasks as good as amiga can? Linux can't.
- So your Toy Operating System beats many bigger OSes just because it is
- smaller. If all OS kernels had the same feature list, we would need only
- one kernel. But different applications need different feature lists, and
- different kernels. and there is still use for a small single user multi
- tasking OS without memory protection. You must not see the missing
- feature, you must see the advantages of a simple, performant design.
- add memory protection to Amiga OS and you remove its main advantage.
-
-
-
- for the user, it is no real problem. in my experience, AmigaOS without
- memory protection runs more stable then Windows 3.1 or 95 with only
- Microsoft applications. so what is the toy operating system?
-
- in a multiuser environment, memory protection is essential because user "A"
- will not tolerate if an error of user "B" crashes his application. in a single
- user environment a user will accept rebooting if an application crashes, and
- if he notices that an application crashes often, he will switch to another
- one. in fact, because of the lack of memory protection on Amiga, most
- professional Amiga applications are very well debugged and usually don't
- crash, in contrast to normal Windows application (Windows is of course
- only a very successfull toy OS to you? well, it's the one we must beat.)
-
- Because of the lack of memory protection, AmigaOS outperforms any other
- multitasking operating system with memory protection. you might say that
- memory and processors are cheap nowadays, but *I* would really like to see
- how Lightwave on Dec Alpha Amiga would outperform Lightwave on Alpha NT.
-
- Now if you tell people that Alpha Amiga runs SoftImage 50% faster then Alpha
- NT, they would pull thier calculator and buy Amiga OS. If the Application
- crashes, it crashes and all data is lost, with or without memory managment.
-
-
-
- but with Amiga Technology going down the toilet and idiots playing around
- on the Power Port, this is all a dream. I gave up Amiga the day I heard
- that Escom bought it.
