08:54 AM KGB-linuxcnc: 03Jeff Epler 05master 0fcfcc4 06linuxcnc Merge remote-tracking branch 'origin/2.7' * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=0fcfcc4
08:59 AM KGB-linuxcnc: 03Jeff Epler 05master aad1cab 06linuxcnc 10src/rtapi/uspace_rtapi_app.cc uspace_rtapi_app: fix use of g++ extension not in clang++ * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=aad1cab
11:42 AM jepler: hm I was going to work on a new iso today but something I've changed broke the installer :-/ it just panic trying to mount the root (initrd?)
11:43 AM jepler: +s
12:40 PM jepler: stupid problem is not my problem, but I have a fix. yay.
12:42 PM jepler: on a 1GB qemu system, latency-plot refuses to run due to its own memory usage :-P
01:10 PM jepler: if all goes according to plans, in ~10 minutes, the "r6" isos will be up on wlo
01:11 PM JT-Shop: r6?
01:12 PM jepler: the strech live images are numbered with "r", so this is the sixth set
01:12 PM jepler: that's just some convention I made up
01:13 PM jepler: still stretch + preempt-rt + xfce + linuxcnc 2.7
01:16 PM jepler: I've played with this 'persistence' feature for a bit and it seems to work. https://github.com/jepler/stretch-live-build/blob/master/README.md#experimental-persistence
01:16 PM jepler: now, all I've put on the persistent image is an empty file in the user's home directory that survives a reboot...
01:18 PM jepler: OK , new set of images is at http://www.linuxcnc.org/testing-stretch-rtpreempt/
01:22 PM Tom_itx: yay
01:23 PM Tom_itx: although i don't think it'll run on my D525
01:30 PM pcw_home: Stretch wont run?
01:50 PM jepler: is that the one that had horrible latency with an earlier image?
01:51 PM jepler: .. if so, that won't have changed.
01:51 PM jepler: however, I think the "ht disabled" bug in linuxcnc should be fixed, since this image has the newest buildbot debs
03:51 PM jepler: digging out old hard drives .. -rw-r--r-- 1 jepler jepler 18140418 Oct 31 2009 emc2-sim_2.4.0~pre_amd64.deb
03:51 PM jepler: I wonder if this version was any good
04:00 PM jepler: ooh this still works https://emergent.unpythonic.net/files/sandbox/dominosweeper.py
04:01 PM jepler: (minesweeper with 1x1 and 1x2 pieces)
04:04 PM jepler: .. a program that reads text on stdin and produces an image of some 7-bit paper tape as you type ..
04:04 PM jepler: what interesting things I did years ago
04:04 PM jepler: https://emergent.unpythonic.net/files/sandbox/tape.py
04:08 PM jepler: an unfinished HAL component https://emergent.unpythonic.net/files/sandbox/interpret.c
04:08 PM jepler: I think the goal was to implement a stack-like language, so that you could write your custom component in a loadrt option
04:10 PM jepler: for example, 01+A would implement sum2; and 0#2*A would double the input value
04:10 PM jepler: wow looks like I even had conditionals with ?(...):(...)
04:12 PM jepler: and indirection! 01! would copy input 1 to the output named by input 0
04:16 PM jepler: .. an exact-stop, 2 dimensional motion planner that runs in userspace and streams to halhttps://emergent.unpythonic.net/files/sandbox/trundle.c
04:22 PM jepler: .. kshm and kth, my attempts to implement kernel-mode realtime for preempt-rt (2009)
04:22 PM jepler: I'm much happier with uspace
04:23 PM jepler: haha a 1% finished modbus implementation (or maybe unrelated serial protocol?) I planned to call "divbus"
04:24 PM jepler: .../tuxcnc/branches/.svn
04:42 PM jepler: (wow tuxcnc.org still operates, nearing 10 years without updates)
04:57 PM KGB-linuxcnc: 03Jeff Epler 05master 5b7929d 06linuxcnc 10src/rtapi/uspace_rtapi_app.cc Merge branch 'freebsd2' of https://github.com/trasz/linuxcnc * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=5b7929d
05:17 PM ve7it: jepler, greetings... you had me going with tape.py... couldnt figure out the codes until I dug around a bit... it outputs EIA codes not ascii or the baudot codes I was used to... can ya tell I am old ?
05:19 PM ve7it: jepler, I might have to add audio fsk tones to tape.py
05:21 PM jepler: ve7it: it's just fun to look at what I was playing with so long ago that I've forgotten why
05:21 PM jepler: ve7it: sounds like fun, adding FSK audio
05:22 PM ve7it: yea... the old projects were pretty cool... exploring what these new fangled computers can do
05:23 PM jepler: looks like EIA tape encoding was used with old CNC, so this was probably something tangential to LinuxCNC..
05:23 PM jepler: http://www.cnc-syntax-editor.com/eia-tape-code.htm
05:24 PM ve7it: most of my old code is trapped on 5 1/4 floppies.... I really should try and image all those before the disks disintegrate
05:25 PM ve7it: I wonder If I could get dos to boot on an i7? I suspect the bois functions needed are long gone
05:26 PM jepler: freedos is still kicking, I read recently
05:26 PM jepler: http://shop.deviceside.com/prod/FC5025
05:27 PM jepler: Drive mechanism is not included. Purchaser must supply TEAC FD55GFR or equivalent drive.
05:27 PM jepler: .. but who doesn't have a pile of 'em in the barn?
05:29 PM ve7it: cool.... I probably have some old boxes in the crawl space with drives installed... I still use 3 1/2 dos boot floppies for programming old 1990's radios with an old laptop
05:31 PM ve7it: I could probably image all the old floppies onto 1 thumb drive... who would have imagined that in 1980
05:50 PM linuxcnc-build: build #3187 of 1405.rip-wheezy-armhf is complete: Failure [4failed compile runtests] Build details are at http://buildbot.linuxcnc.org/buildbot/builders/1405.rip-wheezy-armhf/builds/3187 blamelist: Jeff Epler <jepler@unpythonic.net>, Edward Tomasz Napierala <trasz@FreeBSD.org>
05:50 PM linuxcnc-build: build #5034 of 0000.checkin is complete: Failure [4failed] Build details are at http://buildbot.linuxcnc.org/buildbot/builders/0000.checkin/builds/5034 blamelist: Jeff Epler <jepler@unpythonic.net>, Edward Tomasz Napierala <trasz@FreeBSD.org>
06:21 PM mozmck: I'm curious what advantage FreeBSD might have over linux? What realtime kernel is available?
07:51 PM jepler: mozmck: the intellectual challenge I think
08:10 PM skunkworks: I used to check tuxcnc every so often.. I probably havn't checked in a few years
08:18 PM Tom_itx: yes the D525 had horrible latency with stretch
08:24 PM skunkworks: zfs?
08:35 PM Tom_itx: what is zfs?
08:41 PM Tom_itx: ve7it, i boot dos on an i5
08:53 PM skunkworks: who knows about lvm's?
08:57 PM Tom_itx: servo 506732
08:58 PM skunkworks: I just expanded my hardware raid - and vgdisplay doesn't show the new size (like doesn't show there being free pe)
08:59 PM skunkworks: so it seems like I need to somehow allocate the new space in sda to the lvm. Google hasn't helped me yet
09:04 PM skunkworks: ok pvdisplay shows the physical volume with free pe..
09:06 PM skunkworks: no - that isn't right. it is only showing about 644gb free.
09:09 PM Tom_itx: ht disabled: servo 76516
09:09 PM Tom_itx: and latency test worked with ht disabled this time
09:46 PM Tom_itx: skunkworks is the raid for speed or keeping data safe?
09:46 PM skunkworks: yes
09:46 PM skunkworks: :)
09:47 PM Tom_itx: i haven't got a straight answer yet but if you wanna visit with rue in #robotics i bet he would be knowledgeable
09:48 PM Tom_itx: he says hardware raid is bad for keeping data safe
09:52 PM skunkworks: hmmm
09:52 PM jepler: Tom_itx: thanks for confirming that latency test works with ht disabled now
09:52 PM Tom_itx: seemed a bit better with ht off
09:53 PM jepler: skunkworks: it's been years since I've done lvm, so I don't have much help to offer. :-/ hope you get it sorted
09:53 PM jepler: Tom_itx: for 1ms servo only, 76us is going to be just fine.
09:54 PM Tom_itx: about a 5 min test with light web brousing
10:02 PM Tom_itx is now known as Tom_L
11:02 PM skunkworks: jepler, got it.. Parted to extend sda3 and then the lvm saw the space
11:05 PM skunkworks: I know have a 24TB volume :)
11:06 PM Tom_L: that should last a while
11:06 PM skunkworks: heh - already has 11tb used...
11:06 PM skunkworks: TB
11:07 PM Tom_L: i bet it would take a while to back it up
11:08 PM skunkworks: initally yes - but for us we use a few offsite servers that we rsync every day. so only a few gb per day
11:09 PM skunkworks: and onsite for that matter..
11:10 PM skunkworks: for a full tranfer to a new server takes days.
11:13 PM skunkworks: we have been using mdadm arrays. I wanted to try a real dell server with a decent raid controller. for speed and fault tolerance..
11:14 PM skunkworks: with the initial testing it is gobs faster for file access. Time will tell
11:14 PM Tom_L: is this for a business?
11:14 PM skunkworks: yes
11:15 PM skunkworks: lots of large art files mainly
11:16 PM skunkworks: (printing company)
11:16 PM Tom_L: ahh
