I know that your system is not quite standard, but often in past Debian installs, not only has aptitude not been a dependency, it has not even been there and I have had to install it myself. In fact, there was a discussion quite recently on the Debian list as to whether aptitude should be installed by default. Here is the first post in what turned out a fairly long thread. https://lists.debian.org/msgid-search/375717CA-88D6-4CF6-8D60-2A133DF3552F@… Lisi

And aptitude normally doesnt destroy anything unless you ask it really-really hard, so this hints to it too. On slow links yes, sshfs is strictly superior to nfs, but on 1Gbit and faster links cpu usage becomes a factor, especially on server side. Sshfs would kill a typical nas-grade cpu on 1Gb. -- Nick Koretsky (nick.koretsky(a)gmail.com)

I'm on jessie. I stopped using any kind of package manager other than apt-get and dpkg. regards

But PAE takes time to do the translations, and rtai kills PAE because it needs every cycle it can get to run LinuxCNC if doing software step generation for stepper motors. Put a 20% time wibble in the step generation when the step rate s/b 40 khz and the motor loses at least 50% of its torque at the higher speeds, % of loss going up with the step rate, getting worse as the step rate goes up. With modern drivers that do microstepping*, the step rate coming out of the driver card can hit 300+ kilohertz. But then you are up against the speed limit of the opto-isolators in that micro-stepping drivers input. So those of us who play with steppers, usually have the divisor set so that top rpms is at about 200 kilohertz. Pure software generation is generally all tapped out at 30-35 kilohertz. Your trivia factoid for the day. :) *microstepping, where the driver can control the motors coil currents to do a successive approximation of 2 sine waves, 90 degrees out of phase. The motor then is balanced between steps, making a 1600 step motor out of the basic 200 step per revolution set of windings if the divisor is 8.

Running on the hardware its designed to run on, zero problems that weren't caused by udev when I moved the hd from box to box looking for a usable one in the boneyard. Didn't find one either, had to go over a town and buy a driveless Dell 745 with 4Gb of dram in it. He had dozens, all off-lease. Its as happy as a clam once I figured out how to neuter udev. I will probably go dicker him out of another, dead stable machines to run this much bigger Sheldon lathe I just brought home. Well built, 1500 lbs of cast iron. But I am finding 64 years of use by non-machinists has not been kind to it, many things haven't been oiled in the 64 years its been around. But if I don't fall over, it will get CNC'd, and be at least 10x more accurate than when it was new. And since gcode is write once, run many, its possible it may make more stuff in the next two years than it has made in the previous 64 years running manually.

I simply downloaded the latest Raspbian after an older openSUSE for Pi would not even boot ( in the mean time I got a better understanding of the differences between the pi and "normal" computers). lsb_release answers Raspbian GNU/Linux 8.0 (Jessie) I'll probably try a "Tumbleweed" install when I have another 16GB card available. As I mentioned in previous mails, I followed your how-to and installed tdebase-trinity, then I used synaptic to add TDE programs I would use. Trinity Control Center says TDE 14.0.4 (Development). The Pi is a Pi 3, "Model B" Things seem to run pretty well now, except that the bluetooth keyboard I have behaves eratically. The Bluetooth mouse works ok, so do their USB counterparts. Wifi is working, resolution is set to 1824x984 on my Samsung monitor. Sound is not very good but acceptable if I switch from pulse to alsa. Thierry

Somewhere along the line you got a lot more stuff on your system than I have on mine, e.g. samba... and pulse. I still have more than half of my 16GB card free (USB HDD for video and images). It's good to hear that the new Pi3 hardware features work, disappointing that sound quality hasn't improved.
