That requirement is secure distributed networking interfaces for all

As such I would like to see plugin code developed to allow user
interfaces to have full control of LinuxCnc, along with consolidated
status and errors with plugin interfaces for Python, C/C++ and NML.
Are you talking distributed as in across network or distributed as in
individual distributed packages?
With such a plugin system for user interfaces there is no need to
include anything related to user interface development withing
LinuxCnc code itself since those are all handled as completely
separate projects by the various UI developers.
I guess in my mind this is already true -Qtpyvcp is a separate project
that is added to linuxcnc is it not?
I don't understand why I see so much resistance in getting such a
relatively simple thing done by the experts in LinuxCnc development.
Everyone knows that distributed networking is extremely viable so
there should be no reason not to implement this concept for
interfacing with UI's. You cannot keep on adding UI development things
to LinuxCnc without it becoming a big big mess. I think to do so is
just due to hardheadedness.
Probably because its a actually a lot of work on code that require
specialized knowledge.
I also don't see the 'big mess' part.
i think it's somewhat of an advantage to have everything needed to use
linuxcnc under one project.
For instance i as a mostly ui guy, needs to know almost nothing about
packaging and make files.
This lowers the bar to being a developer on the project.
There is surely some disadvantages too - you are not completely free to
do whatever you want or even whats best.
Lets develop the UI plugin interface concept for LinuxCnc version 10
that allows UI interfaces to run as a distributed data system and
which at the same time simplifies maintaining LinuxCnc a thousand fold
and also reducing the size of its footprint.
I'm not sue it simplifies it - just distributes it among more projects.
Again advantages and disadvantages
.
Its up you, the LinuxCnc developers and also the UI developers to get
started on implementing something like this for LinuxCnc version 10!
You are all the experts and developing the standard code for this is
likely not difficult. For those of us who are somewhat on the outside
the development group we will have to do less customizing work by not
having to customize LinuxCnc to suit our desires and which causes a
great deal of update difficulties.
So one obvious way to help is to become a part of the linuxcnc group
instead of staying on the 'outside'.
Now this can be a frustrating experience sometimes and you will have to
compromise - a lot.
We are currently way too short on developers to do much big changes.
Another way is to develop on the side and work on getting it accepted.
But if your work massively overlaps on going work already in the
project, expect resistance - that is just human nature.
In this case Kurt probably could have avoided this by not disappearing
from qtvcp project. I don't remember any big fights with him. i very
much enjoyed working with him at the time. looking back at it though, it
does seem clear he always wanted to do his own thing - fair enough.
When you look at history there have been a number of warnings that
this needed to be done a long time ago. One such example was the split
and development of Machinekit which I feel was the direct result of
developers being to stubborn to explore other points of view and their
potential long term benefits. Just think about how much was lost by
these two teams not being able to work together to resolve issues.
It is disappointing what happened with machinekit - In truth I think it
should have happened earlier before feeling were hurt and walls were
built up - so that we could come back together with the best of both.
Linuxcnc has always been a slow moving project. It's often frustrating.
But it seems to have something that keeps it popular. I mean Qtpyvcp
isn't using machinekit's network distributed ui system.
