01:55 AM skunkworks: floats?
02:38 AM rene_dev_: Floating point support for sserial slaves
02:56 AM skunkworks: ah
02:56 AM skunkworks: shouldn't you be sleeping? ;)
07:59 AM jepler: hal/components/demux.comp:30:32: warning: suggest parentheses around ‘+’ inside ‘<<’ [-Wparentheses]
07:59 AM jepler: bit = sel_u32 + sel_bit(0) + sel_bit(1) << 1 + sel_bit(2) << 2
08:00 AM jepler: hm this warning makes me suspect the code doesn't do what is is intended
08:17 AM jepler: huh
08:17 AM jepler: Component Pins:
08:17 AM jepler: Owner Type Dir Value Name
08:17 AM jepler: 30 bit OUT TRUE demux.0.out-00
08:17 AM jepler: 30 bit OUT FALSE demux.0.out-01
08:17 AM jepler: 30 bit ??? FALSE demux.0.out-02
08:17 AM jepler: ???
08:21 AM jepler: wee, looks like I get to make more pull requests
09:41 AM pcw_home: demux.0.out-02 suffering from gender confusion?
10:52 AM jepler: I think it's worse than that, rtapi_app goes ahead and segfaults just subsequent to me triggering the "???"
10:52 AM jepler: [6787167.352948] traps: rtapi_app[26530] general protection ip:7fdc1f71afef sp:7fdc218f0ea8 error:0
11:44 AM jepler: I sure didn't anticipate doing this much linuxcnc work this month
11:45 AM jepler: :shrug:
11:49 AM jepler: who was it mentioned being impacted by non-installability of the stretch image without network? I think I have a fix, I'll have a new iso uploaded to wlo later today if you would be kind enough to test.
11:50 AM jepler: It would also benefit from re-testing by someone who needs a device firmware during install for their network (wireless)
11:50 AM jepler: I'll paste a URL once it's available
01:08 PM skunkworks: jepler: Thank you !
01:15 PM jepler: "r13" isos are uploading...
01:15 PM jepler: 13 is a lucky number right?
01:17 PM skunkworks: sure! I have a computer that needs device firmware - I will test it at work
01:17 PM skunkworks: jepler: I finally found a laptop that I can pass the dedicated video to the qemu virtual machine. I am complete now.
01:19 PM skunkworks: I mean - the kids were pretty awesome - but this laptop....
01:22 PM jepler: skunkworks: wow getting accelerated video in a machine that is virtualized with free software is pretty awesome!
01:23 PM TurBoss: a fantastic numbre
01:23 PM TurBoss: *number
01:23 PM TurBoss: :P
01:24 PM jepler: OK the "r13" images are live at http://linuxcnc.org/stretch/
01:24 PM jepler: oh dangit I didn't fix the iso names to have "2.7" in them like seb_kuzminsky requested
01:26 PM Tom_L: what default desktop is on this iso?
01:26 PM jepler: Tom_L: xfce
01:26 PM Tom_L: ok
01:27 PM jepler: same as I have always chosen for the stretch images. you should be able to install whatever desktop environment's "task" you want after initial installation, though.
01:27 PM Tom_L: yeah i should be able to :) i'm not that savvy on changing desktops but it's no matter.
01:28 PM jepler: or build your own image with your preferred DE, it would be a 1-line edit to "do.sh" in the live builder scripts at https://github.com/jepler/stretch-live-build if you really want to go OTT
01:29 PM Tom_L: i didn't use the iso first time through
01:31 PM jepler: that's fine, no reason to reinstall
01:32 PM jepler: unless you want to do it in order to give feedback
01:32 PM Tom_L: it's a test machine. busy right now but if i get a chance...
01:32 PM jepler: heh no worries
01:33 PM Tom_L: i'll just swap out drives so not to disturb my working preempt
01:34 PM jepler: I'll try installing a different DE in my sacrificial VM
01:40 PM jepler: so after installing task-xfce4-desktop, I rebooted. Now, in the menu at the upper right of the login screen (which is still the "xfce"/lightdm login screen), there's a choice of session. I chose "cinnamon", and then entered my login/password. easy as that!
01:41 PM jepler: errr
01:41 PM jepler: after installing task-cinnamon-desktop
01:49 PM jepler: similar with lxqt, except that it also prompted me to change to a different login manager, so after I accepted that and rebooted the login screen looked different as well
01:51 PM jepler: it's wonderful how fast boot/shutdown are, particularly in a VM
01:51 PM jepler: afk
01:52 PM jepler: skunkworks: I'll read back for your testing results
01:52 PM jepler: thanks again in anticipation
02:07 PM * JT-Shop takes notes
02:21 PM hazzy-m: jthornton: I think I fixed at least some of the mark up errors, but the docs have not been built since my PR was merged, not sure what it up
02:21 PM hazzy-m: its been a week or so
02:22 PM JT-Shop: hazzy-m: you fixed the markup errors on M3 4 5 in master?
02:22 PM JT-Shop: should only take an hour or less to build the online docs
02:22 PM hazzy-m: yeah, it says last updated 2018-10-18
02:23 PM hazzy-m: JT-Shop (IRC): I think I only worked on the python interface docs
02:23 PM hazzy-m: can't remember for sure, lol
02:24 PM JT-Shop: naw Andy was the last one to work on that... I'll fix it in a bit
02:24 PM hazzy-m: oops, sorry, I thought I was in the other chan
02:25 PM JT-Shop: no your lost lol
02:27 PM Tom_L: is this image on the main download page?
02:28 PM JT-Shop: main download page? do we have one?
02:28 PM Tom_L: http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
02:29 PM Tom_L: didn't notice it
02:29 PM JT-Shop: nope http://linuxcnc.org/stretch/
02:29 PM Tom_L: so it's not for prime time yet?
02:29 PM JT-Shop: dunno why stretch is somewhat hidden
02:29 PM JT-Shop: beats me
02:29 PM JT-Shop: I've been using it for a long while
02:29 PM Tom_L: i figured it would be on the main page by now
02:32 PM Tom_L: JT-Shop are you running the 64bit ver?
02:35 PM JT-Shop: aye
02:35 PM Tom_L: downloading... i'll have to see if i have a spare ssd here
02:36 PM JT-Shop: I'll dig up my notes to make stretch user friendly in a bit
02:36 PM Tom_L: i did a previous install from scratch
02:37 PM JT-Shop: https://paste.ubuntu.com/p/wBx3zb3sGZ/
02:39 PM Tom_L: i tried to get the autologin to work but so far it's not
02:40 PM Tom_L: and apparently i lost my previous 2 install links
02:41 PM Tom_itx: https://paste.ubuntu.com/p/jvDN76Pq7Z/
02:42 PM Tom_L: woops, damn cut n paste fails again
02:42 PM JT-Shop: you probably edited the wrong thing
02:42 PM Tom_L: err no that's a different link than yours
02:47 PM Tom_L: now to remember how to do a bootable thumbdrive..
02:57 PM jepler: https://github.com/LinuxCNC/linuxcnc/pull/500 -- here's the PR for making stretch "official". I think the last remaining thing is, seb_kuzminsky requested that the iso filename all say "2.7" in them.
03:01 PM Tom_L: so are they dropping RTAI from here forward?
03:06 PM jepler: RTAI support remains in the linuxcnc source tree, but having a ready to ship RTAI kernel that runs on a wide array of hardware and on the buildbot has not materialiezd.
03:06 PM jepler: materialized
03:08 PM skunkworks: jepler: yes - it is amazing... http://electronicsam.com/images/KandT/testing/primus/passthrough.png
04:59 PM hazzy-m: skunkworks: Is that a win10 VM running F360?
05:48 PM skunkworks: hazzy-m: yes
05:53 PM skunkworks: hazzy-m: http://electronicsam.com/images/KandT/testing/primus/benchmark1.png
05:53 PM skunkworks: the fans scream... ;)
