"pure" Managed OS
Sooos will not be a pure managed OS , like Cosmos SharpOS or Mosa , or even Singularity ( which has a small amount of C++ code)...
I still feel that GC technology has some way to go and at present the performance penalty is too bad for certain functions. This is especially so for writes as most GCs todate implement a write barrier which can more that half write performance , that said as we go to higher core counts it may be more efficient to remove the write barrier.
In particularly 3D and some mathemetical modelling which need to work...

Managed OS
Just an update on what I have been up to. I don’t have a lot of time and what little I have im spending on the kernel.
Some back ground
The key challenges to moderns OS are
1. Security ( more specifically hacking through 3rd party services likes Flash and limiting the damage from users allowing bad apps)
2. Reliability
3. Resiliency eg recovering from a critical failure
And to a lesser extent
4. Difficulty in managing change to an OS
5. Handling the Asynchronous nature of the internet
6. Handling multi cores efficiently
SOOOS ( Service Oriented Object Operating System) is a OS that scales from embedded to GP. It is not a...

The End of Linux ...and Windows
New generation of OS coming.
Operating Systems are about to enter their 4th generation with a revolutionary change. These being
Basic
TimeSharing
Hardware memory protection ( most were UNIX/MULTICS derived designs)
Managed OS. ( or OOOS)
While Singularity/Midori is a Manged OS it is still a traditional style OS. Not all 4th gen OS will be so traditional , things a operating system does like memory segmentation are not even needed.
A better name for these OS may be an...

Midori To be or not
Just read this article and had to respond/..
http://www.computerworld.com.au/article/255954/windows_midori_doomed_failure
On a number of facts its just wrong , particularly.
1. Microsoft wants to evolve.
2. Its unnecessary as windows Kernel is light and replacing the kernel will not solve the security and DLL problems.
3. The purpose behind a new OS
4. Backward competability
Note this is based on Midori being a Singularity style kernel.
1. Microsoft wants to evolve.
Dont know about MS desire to evolve ..
