Are you talking about image or serialization of objects?

Look at OSWindows in Pharo we are in transition.

Can you tell us more?
We have different systems
- miniimage which is built automatically by removing packges and
this is working so may be you use the wrong vm.
- bootstrapped kernels
will be in production in Pharo 60
- specialized image
we got down to 11k for 2+3 and 18k for 20 factorial
this is experimental but hyper fun.

Yes we build that for Thales

It depends what you want to do. if this is real time, Pharo is not
a real time os
After Thales are migrating to Pharo for their "prototype" of new

We should do a pass on the Android VM and its event.

Lack of Marketing is the reason. Not the technology.

I do not know.

it is an old paper. When I arrived from CLOS I wanted to know if I could
do the same.
Now I know and we can certainly do better at the MOP level.
