[04:09:53] <archivist> two channels of spam and no ops awake
[05:09:41] <mk0> call him someone ))
[05:10:38] <archivist> mk0, https://www.nic.ru/cgi/whois_webmail.cgi?domain=PSHA.ORG.RU
[07:01:14] <JT-JA> the last time I built rt my instructions were wget https://www.kernel.org/pub/linux/kernel/projects/rt/4.4/patch-4.4.1-rt5.patch.gz
[07:01:34] <JT-JA> that patch is not there anymore and I tried with the new one but it would not build
[07:03:45] <JT-JA> http://pastebin.ubuntu.com/16062048/
[07:04:03] <JT-JA> I did use the config pcw_home gave me... maybe that is the issue
[07:08:29] <skunkworks> zlog,
[07:12:08] <skunkworks> dgarr: wow - awesome!
[07:14:03] <jepler> JT-JA: https://www.kernel.org/pub/linux/kernel/projects/rt/4.4/ is a directory listing
[07:14:12] <jepler> looks like somebody decided to keep things tidy by moving patches to older/
[07:14:53] <JT-JA> ah I didn't even see the older directory, thanks
[07:17:31] <skunkworks> jepler, I switched to master/eth-packet-loss and now when I try to run a program I get an instant joint following error
[07:18:35] <skunkworks> (stepper config from peter)
[07:20:48] <skunkworks> (pid)
[08:12:55] <jepler> skunkworks: ok that's good information :-/
[08:13:26] <skunkworks> well - it may be partially the config.
[08:13:39] <skunkworks> I can get the program to run at 60ipm
[08:14:53] <skunkworks> anything above a few hundred ipm it throws a following error
[08:16:21] <skunkworks> would you like me to tar it and send it to you?
[08:16:40] <jepler> It would probably help me get started
[08:16:56] <jepler> you think/know it would run at 100ipm on master branch?
[08:19:24] <skunkworks> I am pretty sure (that is how I had been testing) but I am switching back to master now to double check
[08:26:40] <skunkworks> works in master
[08:26:47] <jepler> OK I must have messed something up
[08:27:20] <skunkworks> http://electronicsam.com/images/KandT/testing/peterlastes.tar.gz
[08:28:15] <jepler> can you give me a halscope screenshot of it hitting a following error?
[08:32:03] <jepler> (not that I won't be able to reproduce it myself once I get the chance)
[08:36:09] <skunkworks> sure - give me a bit
[08:47:44] <skunkworks> jepler, http://electronicsam.com/images/KandT/testing/Screenshot-9.png
[08:58:23] <skunkworks> seems to slightly fall behind
[09:22:14] <jepler> skunkworks: yeah that is how I'd describe it too
[09:24:07] <cradek> maybe it's error proportional to velocity
[09:31:33] <jepler> I assume the offset when stopped is pid deadband or something
[09:34:02] <skunkworks> I might not have lined them up perfectly.. maybe..
[09:34:02] <jepler> I bet I botched something about the "how long to wait" code when I made it configurable
[09:34:35] <jepler> and I forgot an important thing: I need to know if a read-response corresponds to this read-request
[09:35:15] <jepler> because if in cycle X you give up waiting for a response that arrives late, in cycle X+1 you'll read that previous response first
[09:35:24] <jepler> and forever after you're a cycle off in your feedback
[09:38:01] <skunkworks> wow - how do you know once you caught up to then use the correct response.
[09:38:44] <jepler> once I can detect that it's the wrong response packet, just jump back to trying to receive the right read-response
[10:17:07] -linuxcnc-github:#linuxcnc-devel- [13linuxcnc] 15pkmcnc opened issue #56: ja: auto-switch to world mode fails for some configs 02https://github.com/LinuxCNC/linuxcnc/issues/56
[10:31:42] <dgarr> re ja issue #56 -- not enough info,need commit, inifile ,did he set [KINS]AUTO_TELEOP=timelimit?

[11:23:43] <cradek> uh
[11:40:35] -linuxcnc-github:#linuxcnc-devel- [13linuxcnc] 15pkmcnc commented on issue #56: Thanks a lot!... 02https://github.com/LinuxCNC/linuxcnc/issues/56#issuecomment-214798000
[18:34:53] <seb_kuzminsky> yay, hackspace night!
[18:40:13] <jepler> seb_kuzminsky: yay
[18:40:29] <jepler> oh phew "thanks a lot!" was not sarcastic on that github issue
[19:57:54] <jepler> >
[19:57:54] <jepler> NOTE: The following commands will require root user permissions. You might want to run sudo su - first.
[19:57:57] <jepler> <
[19:58:28] <jepler> why in the world would you "sudo su -"? "sudo -s" / "sudo -i" give you a root shell / root login shell.
[19:58:44] <jepler> I see this "sudo su -" advice popping up more and more places and I can't fathom the motivation
[19:59:09] <jepler> (that is from a rando web page, not linuxcnc documentation)

[21:15:11] <cradek> core2duo with onboard parport that works with the pluto
[21:16:45] <jepler> sure is an interesting distribution to the left of 0
[21:17:15] <jepler> but yay, glad you can upgrade that PC
[21:17:27] <jepler> I'm still smarting from the whole afternoon we waited for it to build ja#

[21:20:42] <jepler> (author has been diagnosing a failed VT100 PSU)
[21:42:49] <cradek> yeah the old one is P3-400 with 256MB or somesuch, fine for running but not much else.
[21:43:29] <cradek> heh *one* problem is that transistor
[21:43:52] <cradek> another problem is all the caps

[22:02:13] <cradek> wow I had a friend who had one (or more?) of these?
[22:02:22] <cradek> the arm was as useless as it looks, but the thing would drive around
[22:02:57] <cradek> when you booted it, it would say UHREADY in three syllables which was endlessly entertaining
