10:36 AM jepler: seb_kuzminsky: how can I talk you into spending the time to make a debian stretch builder?
10:55 AM seb_kuzminsky: i think you just did
11:07 AM jepler: really? awesome
11:07 AM jepler: then can you poke it in such a way that 2.7.9 packages come out?
11:08 AM jepler: actually.. I think debian/configure needs a patch before that :-/
11:08 AM jepler: https://emergent.unpythonic.net/files/sandbox/0001-debian-configure-stanza-for-debian-stretch.patch
11:19 AM jepler: seb_kuzminsky: OK to commit to 2.7? I'll take care of the merge to master right away too, I'm sure it makes a conflict.
11:29 AM seb_kuzminsky: yeah, go for it
11:29 AM seb_kuzminsky: i'll make a 2.7.10 once i get the new builders up
11:30 AM jepler: are you doing 32- and 64-bit uspace builders for stretch?
11:39 AM seb_kuzminsky: it's probably enough to do 64-bit
11:39 AM seb_kuzminsky: i could easily do both if you think there's value to it
11:40 AM jepler: you said "builders" plural so I was wondering what you meant
11:40 AM seb_kuzminsky: dont believe anything i say
11:40 AM KGB-linuxcnc: 03Jeff Epler 052.7 6a5f7c0 06linuxcnc 10debian/configure debian/configure: stanza for debian stretch * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=6a5f7c0
11:46 AM skunkworks: jepler, boots on the matsurra - decent latency
11:46 AM KGB-linuxcnc: 03Jeff Epler 05master bc642c8 06linuxcnc Merge remote-tracking branch 'origin/2.7' * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=bc642c8
12:11 PM skunkworks: jepler, the livecd goes into screen saver/lock. what would the username/password be?
12:11 PM jepler: skunkworks: ummmmm good question!
12:12 PM skunkworks: internet says user/live
12:13 PM skunkworks: that is it
12:13 PM jepler: OK good
12:13 PM jepler: I don't like the new screen locker and just totally disabled it locally
01:12 PM IchGucksLive: hi all
01:12 PM IchGucksLive: what is that new stepconf wizard doing in the ini
01:12 PM IchGucksLive: i now got AXIS and joints
01:12 PM IchGucksLive: how in this low level buttron press world shoudt we treatch people what goes where
01:13 PM IchGucksLive: as there are 2 entris now in the ini
01:16 PM IchGucksLive: so bye hand editing you need to keep the axis_ now in word and Joint in sync
01:17 PM seb_kuzminsky: IchGucksLive: http://linuxcnc.org/docs/devel/html/getting-started/updating-linuxcnc.html#_updating_configuration_files
01:17 PM seb_kuzminsky: that tries to explain the ini changes that went into linuxcnc since 2.7
01:17 PM IchGucksLive: im on a new one
02:24 PM cradek: heh the screen locks itself when booted live?
02:24 PM cradek: there's always so much dumb stuff to fix
02:57 PM jepler: Fetched 1400 MB in 12s (114 MB/s)
02:57 PM jepler: I'm glad I got one of the caching proxies working!

03:42 PM jepler: quite a bit of space is required for the full internationalization!
04:01 PM jepler: after some googling I think I know how to disable light-locker by default without ruining anything
04:03 PM seb_kuzminsky: are you using a realtime kernel from debian.org's stretch package archive?
04:10 PM jepler: seb_kuzminsky: that's right
04:10 PM jepler: 4.9.0-3-rt-{amd64,686-pae}
04:12 PM seb_kuzminsky: that's the best news i've heard all day
04:14 PM seb_kuzminsky: how many times is this you've singlehandedly pulled the project out of a tar pit now?
04:14 PM seb_kuzminsky: thank you!
04:22 PM jepler: heh
04:22 PM jepler: lucky for me it turns out to be easy this time
04:22 PM jepler: as long as you don't want RTAI
04:22 PM jepler: OK, yay, that's the screen-locker issue sorted I think
04:22 PM seb_kuzminsky: the more time passes, the less i want rtai...
05:05 PM pcw_mesa: Testing some 7I92s, all new ones failed to communicate, (couldn't ping)
05:05 PM pcw_mesa: turns out the initial MAC address is bogus (0xFFFFFFFFFFFF) and some
05:05 PM pcw_mesa: switches drop packets with this MAC address
05:06 PM pcw_mesa: (and new place Ethernet wiring was all different)
05:06 PM seb_kuzminsky: that's the ethernet broadcast address,
05:09 PM pcw_mesa: I think I had code to use a fixed (Mesa) number for the MS byte of the MAC (ignoring the EEPROM MSB data)
05:09 PM pcw_mesa: But I dropped it for someone who want their own MAC addresses
05:16 PM pcw_mesa: only an issue for first time card initialization (with blank EEPROM)
09:16 PM jepler: .. uploading a new revision of stretch/preempt isos
09:17 PM jepler: the screen locker should not activate anymore
09:17 PM jepler: the image is much smaller
09:17 PM jepler: ~40% smaller
09:17 PM jepler: there's an i386 (well, i686-pae really) version too
09:18 PM jepler: I supposedly just got an upgrade to 10 megabit upload on my home internet, but I'm only getting ~256kB/s upload which is like 25% of what I'd hoped to see. :(
09:18 PM jepler: maybe it's creeping up slowly
09:19 PM Tom_shop: rather surprised updating from ubuntu 10.04 to debian wheezy i made no edits to the configs and the mill fired right up
09:20 PM jepler: excellent!
09:20 PM Tom_shop: my thoughts exactly...
09:20 PM jepler: if you keep the same LinuxCNC version and same RTOS that is what we hope for
09:20 PM Tom_shop: rtai
09:20 PM jepler: (or even if you change from rtai to rt-preempt, as long as you are using an fpga card and not software stepgen)
09:21 PM Tom_shop: yep, all mesa
09:21 PM Tom_shop: k, goin inside to work on some cad cam...
09:21 PM Tom_shop: just thought you'd like to hear
09:22 PM jepler: do good work
09:22 PM Tom_shop: making some jigs for woodworking things
09:22 PM Tom_shop: laters..
09:30 PM jepler: linuxcnc-stretch-uspace-amd64-r1.iso
09:30 PM jepler: 373,129,216 32% 600.00kB/s 0:21:18
09:30 PM jepler: I guess the speed is creeping up a bit over time, or else just alternately fast and then slow
10:13 PM jepler: OK the new ("-r1") amd64 iso is up
10:14 PM jepler: git source for the generating scripts remains at https://github.com/jepler/stretch-live-build
10:14 PM jepler: i386 version will be up later
10:23 PM skunkworks: jepler, cool - thanks
10:38 PM jepler: i386 is done too
10:40 PM skunkworks: huh - the latency on the j1900 is about 140us
10:40 PM skunkworks: even booted to the system we are using
10:40 PM skunkworks: never had an issue
11:00 PM skunkworks: isolcpus really works well - now it is 13us
11:00 PM skunkworks: again - that is stepper numbers
