03:22 AM st12: did not push stuf fyet
03:26 AM st12: if you are willing to take a look i'll push as is, c part, also tests fixed, for c the only concern is hal.shm, i'll just disable that, also wanted to update the old tkinter axis/gremlin(gtk3)/ gmocappy stuff (whatever stuff my hands able to review and i had time) rene_dev_
03:27 AM st12: mozmck: nope, im not randy
04:07 AM -!- #linuxcnc-devel mode set to +v by ChanServ
05:24 AM rene_dev_: St12 ah, so the hal is not working?
05:24 AM rene_dev_: Probably best not to touch Gmoccapy, there is already a new version, in a feature branch.
05:25 AM rene_dev_: Probably best to leave that to norbert to fix that
06:09 AM st12: hal.shm
06:10 AM st12: did not even see tests for that
06:17 AM rene_dev_: There is no test as such
06:17 AM rene_dev_: But all the test use python hal module
06:18 AM rene_dev_: So they fail if it doesn’t work
06:18 AM st12: i'm not talking about entire hal module, actually all tests pass
06:21 AM st12: i'm talking only about hal.shm shared memory objects, the only examples i did found are from maill lists from 2011, someone was asking whether we need that or not, with no answer
06:21 AM st12: see below:
06:21 AM st12: https://sourceforge.net/p/emc/mailman/message/27872999/
06:50 AM rene_dev_: What does that do?
06:50 AM rene_dev_: I still don’t understand why I cant run your branch with python 3
07:00 AM * st12 sent a long message: < https://matrix.org/_matrix/media/v1/download/matrix.org/KlzYKAyjZehrxEiVQODcNvVY >

11:27 AM mozmck: seb_kuzminsky: are you here?
11:35 AM JT-Shop: mozmck: using gitalong where do you put your github credentials? I can't seem to push even after give my username and password
11:36 AM mozmck: I use ssh so I never have to give credentials.
11:38 AM mozmck: I'll have to find it again, but basically if you have an ssh key, you can upload it to github, and then use git@github.com and it uses your ssh key and you don't need to enter username or password.
11:39 AM JT-Shop: ok thanks
11:39 AM mozmck: I would think though that it would ask your credentials if it failed to push - odd
11:43 AM JT-Shop: yea odd
11:43 AM JT-Shop: I forgot what I did with git kraken lol
11:45 AM mozmck: JT-Shop: https://github.com/gitahead/gitahead/issues/164
11:45 AM mozmck: How do you like GitAhead compared to Kraken? I didn't use Kraken and have not used GitAhead much yet. I like the interface overall so far
11:46 AM mozmck: It is nice for searching and viewing history for sure.
11:54 AM mozmck: JT-Shop: looks like if you cloned the repo using the https link, then you would have to change the origin for the repo if you want to switch to the SSH method. https://stackoverflow.com/questions/7548661/git-github-cant-push-to-master
11:58 AM JT-Shop: thanks and yes I did clone each repo
01:03 PM st12: rene_dev_:
01:08 PM st12: rene_dev_: if you wanna see current status: https://github.com/strufkin/linuxcnc/tree/py3-work
01:08 PM st12: it compiles, most tests pass (there some unexpected behavior related to buffered nature of print stuff, actuall all tests pass if you run them manually)
01:08 PM st12: let me know what needs to be fixed/ported first
04:17 PM andypugh: Not having that much luck with the live-CD scripts
04:34 PM JT-Shop: I tried jeff's once and it used up 1/2 months worth of bandwidth before I realized what it was doing
04:38 PM andypugh: Well, I have no bandwidth shortage, and very fast internet, but the problem is that the scripts want URLs that I have not found alternatives to.
04:38 PM andypugh: I wonder if I can edit the files on the ,iso directly?
05:12 PM JT-Shop: URL's that are out of date?
05:12 PM andypugh: Yes. See the message to the dev list
05:13 PM andypugh: I have also failed to get Stretch working with an RTAI kernel.
05:13 PM JT-Shop: the mailing list? I need to subscribe to it again...
05:19 PM JT-Shop: I assume it's still the source forge mailing list?
05:28 PM JT-Shop: oddly enough they seem to be there http://archive.debian.org/debian/dists/wheezy/main/source/
05:30 PM andypugh: I think that some stuff is there, but not updates
05:32 PM JT-Shop: the directories look the same between jessie and stretch
05:34 PM JT-Shop: hmm wheezy/updates... is a Hit while wheezy-updates are all Err
05:36 PM andypugh: Hmm, yes, but where does that text come from?
05:36 PM JT-Shop: jeff's brain I think... your running his build script?
05:37 PM JT-Shop: https://github.com/LinuxCNC/stretch-live-build
06:01 PM rene_dev_: andypugh I decided on the august date, but cant remember which one
06:02 PM rene_dev_: andypugh which one do you prefer? you can put it on the frontpage if you want.
06:03 PM andypugh: JT-Shop: Trying to do RTAI, so that seems to mean Wheezy (or, potentially, Jessie)
06:03 PM andypugh: rene_dev_: Tell me the date, I will put it up.
06:03 PM andypugh: (need a link too, I guess)
06:04 PM jthornton: have you managed to build RTAI kernel for wheezy?
06:04 PM andypugh: No
06:04 PM andypugh: But we don’t need to.
06:05 PM jthornton: oh is there one you can just use/install?
06:06 PM rene_dev_: honestly, why dont we give up on rtai. its not going to work with newer OS
06:07 PM rene_dev_: andypugh 3rd or 31st
06:07 PM rene_dev_: Im still making up my mind
06:07 PM andypugh: Does preempt-rt give decent results with the parallel port?
06:08 PM andypugh: (not that I am personally against giving up on that too)
06:08 PM jthornton: actually on Lubuntu I'm getting pretty low latency with rt preempt
06:08 PM andypugh: If we give up on rtai and xenomai then the build system gets simpler too, I guess .
06:09 PM andypugh: (My concern is that nobody currently active actually understands the build system)
06:09 PM rene_dev_: you can use the parport with rt preempt
06:09 PM jthornton: I have the same concern
06:10 PM andypugh: Maybe I am worrying needlessly and I am the only one sho doesn’t undertand it
06:10 PM rene_dev_: but yes, maybe in 2019 its time to abandon that as well
06:13 PM jthornton: well I just figured out how to add something to the News section of LinuxCNC
06:26 PM Tom_L: news?
06:27 PM jthornton: yep
06:28 PM Tom_L: if rtai is dropped will preempt-rt still support pp?
06:31 PM jthornton: anyone remember where the old Live CD's are?
06:35 PM Tom_L: http://linuxcnc.org/docs/html/getting-started/getting-linuxcnc.html
06:35 PM Tom_L: those?
06:36 PM jthornton: only see one live cd on that page]
06:44 PM Tom_L: some may have been removed, i'm not sure but i'm not finding them either
06:47 PM jthornton: http://linuxcnc.org/2006/09/17/026-emc2-ubuntu-livecd/
06:47 PM jthornton: google found that one
06:48 PM Tom_L: http://linuxcnc.org/2008/05/15/051-ubuntu-804aemc2-live-cd/
06:48 PM Tom_L: bunch of dead links
06:52 PM rene_dev_: Tom_L yes
06:53 PM jthornton: http://linuxcnc.org/iso/
06:53 PM jthornton: rene_dev_: I can add an announcement to the home page when you're ready
07:02 PM rene_dev_: jthornton yes, I need to talk to the guy before I can set the date...
07:03 PM jthornton: ok, I've got a handle on the wlo now I think so I can work that as needed
07:06 PM andypugh: Ooh! I might be getting somewhere with live-build
07:07 PM andypugh: I was editing a generated file, rathe than setting the command line options.
07:07 PM andypugh: (I needed:
09:08 PM CaptHindsight: https://github.com/NTULINUX/RTAI is the last stable RTAI
09:09 PM CaptHindsight: anything newer at rtai.org is just unstable beta
09:10 PM CaptHindsight: I don't know why people are having problems getting the above RTAI to work, we have it working with Gentoo and even Scientific Linux
09:11 PM CaptHindsight: the version of Debian shouldn't matter either
09:22 PM Tom_L: CaptHindsight lookin for a monitor? better wait for 8k
09:23 PM Tom_L: https://www.youtube.com/watch?v=Uh_QOikSlT4
09:25 PM CaptHindsight: not much 8k source yet out there
09:25 PM Tom_L: no but it won't be long
09:26 PM CaptHindsight: we are actually using 4K monitors with LCNC for 3d printers
09:26 PM CaptHindsight: the images used with the light engines and lasers are projected and previewed in 4K
09:28 PM CaptHindsight: we will use 8K projectors as they drop in price
09:29 PM CaptHindsight: https://www.digitalprojection.com/emea/dp-projectors/insight-laser-8k/ is currently ~$300K
09:31 PM CaptHindsight: http://pro.jvc.com/prof/attributes/features.jsp?model_id=MDL102550 not true 8K for $18K
10:59 PM mozmck: cradek: you around?
