And it won't boot, grub, by the time its installed, is too far into the
drive, and this dumbassed bios can't find it. So I'got to rethink my
partitioning scheme to add a 250 meg /boot up front...
Ok ... thing one: don't use "sudo", use
"su". "sudo" is like a choir
of castrates: useless by default, unless you invest hords of time to
set up things correctly and solve a problem that does not exist in the
first place.
Second thing, IMO Debian bites you. All that workarounds to get
systemd+gnome kindof working kill your "user experience". Note: if it
works, you are fine, a bit slow when booting but you get shiny surface
... at least till it breaks, then the fun starts .. and break it will
..
(I already hear the bonfires roaring ..)
And the chain saws snarling as they cut some more to feed the flames.
Wheezy's paranoia was something you could work around most of the time
without too much trouble until xhost got castrated. A good
distribution. Jessie was a taste of whats to come. Stretch makes it
worse. But we're gonna have to live with buster for a while, so we may
as well figure out how to make it work, and sooner is better bause you
get to run it longer. Actually. jessie on the pi wasn't too bad. I am
actually getting things done with it. But info on the wintel stuff is
common knowledge. Want to replace the armhf (pi) or arm64 (rock64)
kernel with a realtime version? Nobody else sees the need, so your
questions get ignored, not answered by the people who do have it all
figured out. Thats BS.
And its why I'm back to an intel machine for my current build. The atom
boards can run a 32 bit kernel with IRQ latencies in the 3 to 5
microsecond range, so simple machines can be run directly from the
parport. Need more i/o than the 5 inputs that gives? Mesa has several
boards for under a $100 bill for that, including SPI interfaced that run
at 41 megabaud on the pi. Unforch its a 3.3 volt board, easily damaged
by noise, so it needs 7i42TA buffer boards, 1 for each group of 24
lines, so by the time you've a full 72 line interface, you're at about
$200. But you are also looking at bringing a wire to it, insert in hole
and tighten the screw, so wiring it up is a piece of cake. Then on this
latest build, I chose a $120 7i76 board, driven by an $80 5i25, gives me
5 axises worth of stepper controls, an isolated vfd spindle control, 32
inputs for machine status, and 16 more outputs to run pumps and such
with. And thosee fpga boards take care of the high speed timings so it
all runs on a 1 millisecond main IRQ loop. Power to throw away on a
dual core atom. Plenty of time left to drive your eye candy which I am
not allergic to writing. That also explains why those nearly decade old
atom boards sell on ebay for more that they sold for new. Intel
accidently made us machine tool people an ideal board.
But I'd better shaddup go see what the missus wants for breakfast.
Take care Nik.
Cheers, Gene Heskett
