Hello,
I am new to Pharo and would like to understand a few things.
I can search by myself, but I do not know the code base yet, so:
[Questions]
Pharo image:
Serialization, deserialization, where is the code?
Are you talking about image or serialization of objects?
Pharo vm (Cog/Spur):
Rendering loop and event loops. done with SDL2, where is the code?
Look at OSWindows in Pharo we are in transition.
Message passing, object hierarchy lookup, where is the code?
in the VM
Pharo minimal:
How to get a working version? The builds I tried (4.0) crashed.
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.
[Purpose]
My goal is work out an image/vm with minimum overhead. For example,
let's say I want to build a modern multi-touch application.
Yes we build that for Thales
Pharo's environment looks promising on the live coding/debugging side,
but what about the performance?
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
interactive UI.
Lack of responsiveness would not be
acceptable (think about design differences between Android/iOS).
We should do a pass on the Android VM and its event.
[Context]
I want to understand if the object oriented nature of Smalltalk is
the reason for the lack of apps of this nature (as far as I can tell).
Lack of Marketing is the reason. Not the technology.
Squeak run on PS2 in 300 k back in 2002 or befor.
For example, games have been done with Lisp: Jack and Daxter (on the PS2,
by Naughty Dogs). There are also game engines for the JVM
(https://www.lwjgl.org/).
Dedicated hardware has been built for either Lisp or Forth. I can't seem
to find any hardware built specifically to power Smalltalk software.
Yet as far as I can tell, it's the big time for software virtual machines,
because the new generation of hardware will be supporting them.

I do not know.
UPDATE: I am reading through "Evaluating message passing control
techniques
in Smalltalk"
(https://www.researchgate.net/publication/2440118_Evaluating_Message_Passing_Control_Techniques_in_Smalltalk).
I am getting a better picture of the whole, please direct to more such
papers.
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.
Thanks,
