I do plenty of research but my collegeus are most busy with meetings. Unless 
they make to much noise or put some obstacle in the path of getting something 
useful done I do not care to much.

I however try to involve collegeus, quite often however without response.

So do I Eric, except here its a kmail folder. Same thing except the whole 
email corpus is on this machine, not some other machine with a corporate 
interest in what my email contains so they can more efficiently spam me. 
And at least 80% of my posts goto the users list. The sudden onset of 
following errors did seem to be a question that should be asked on the 
developer list as it started w/o my doing anything except keeping the 
machines up to date from master a couple times a week, and it was 
rapidly answered, and fixed.

One thing I think I do well is playing the canary in the coal mine, so 
stuff like this gets caught and publicized back to the developers  
before it gets into an official release. In my case its a 99.99% total 
loss shop, so being laid up for a bit while such things get smoothed 
over does not disable an income producing machine.

I never did sub to the machinekit list since they tend to think the bbb 
is the best, but its architecture needed a major rewrite of lcnc to run 
on it. Or so it seemed to me. Here, running it on a pi 3b pushes the pi 
a bit but still gives decent results.

My only pi os problem just showed up 2 or 3 days back, there is a new 
video driver, I assume is faster, but it also married to the latest 
raspbian kernel, which is NOT an RT kernel, and no one has built the 
more recent RT kernels (that actually work)for the armhf yet. I have but 
then how does one install it on a u-boot machine?. Questions about that 
have been ducked or ignored on the raspian forum, little if any interest 
in machine controllers there. And no interest in starting a mailing list 
in that camp.  There are other, much faster one board sbc's (rock64) out 
there, but with essentially zero support, much less than the pi has. So 
I'm essentially stuck with the pi. I can build an RT kernel for the 
arm64 on the rock64 in about an hour, but questions about how to install 
it have been ignored on their forum, repeatedly. Ditto with odroid-c2.

Thanks Erik

Right now I am mainly concerned about linear state space. There are a few 
things I think about then in come to feedback. I also need to do estimation of 
constants in the model as well as check how well the dynamics fit with the 
theory.

It is goint slowly forward usually an hour a few each day.

I did, even wrote a diploma thesis on that subject, but this was some 40 
years ago... Since then, I rather managed people doing research on it.

That's quite a problem, and I recently stumbled over a pile of logitech 
k-360's which have square sided keys, which don't jam as easily, and 
bought the pile. Acer also has a maskless keyboard which doesn't jam a 
key down very often, but it has so many "media keys" along the edges 
that there is no place to grab it and pick it up to take it closer to 
the machine while doing the setup. Pressing one of those keys, which may 
do all sorts of odd things is unavoidable. So I keep it for emergency 
use only. Its also about an inch taller, and 4 or 5 inches longer than 
the k-360. The k-360 is a bit smaller than most $20 keyboards.

yes, very busy. Looking something up there is for training I guess, but 
looking up the shortcut can't be called a shortcut. :)  You've got to 
commit them to muscle memory before hand. Unforch, I've reached that 
age, 84, where the short term memory darned near isn't.
