[02:46:19] <jepler> did you figure out why yet?
[02:46:37] <jepler> I notice that in the backup, docs was a symlink to stage-docs

[03:48:38] <jepler> i have a vague memory that this is a thing configurable in the panel, that long long ago the docs were actually served from ~jepler on dreamhost...
[03:48:51] <jepler> but we can't look at the panel, of course
[03:51:53] <mozmck> can SWP give others access to the panel?
[03:52:58] <jepler> mozmck: I asked him about this and he said
[03:52:59] <jepler> 18:45:56 <SWPLinux> I think there are weirdnesses with the way DH gives access to accounts
[03:53:08] <jepler> 18:46:35 <SWPLinux> something where accounts created later can't access accounts that were created earlier (ie, where the content lives ...)
[03:53:19] <mozmck> That's true

[03:53:46] <mozmck> So if he has other things hosted there he may not want to do that.
[03:53:49] <jepler> right
[03:53:57] <jepler> apparently alex_joni has an account that *can* access the linuxcnc.org stuff
[03:54:12] <jepler> so when he comes back, I hope he will make sure others among us have the login credentials
[03:54:29] <jepler> but he's not around very often unfortunately
[03:54:30] <mozmck> I think though that he can add people to the account and give them access to only one site.
[03:55:08] <mozmck> This is different than adding users, and I may not understand it all correctly.
[03:55:15] <jepler> I don't know enough about how DH works, that's for sure

[03:56:13] <seb_kuzminsky> fix'd it
[03:56:16] <mozmck> yes
[03:56:37] <seb_kuzminsky> here was a symlink named "docs", pointing at ~emcboard/stage-docs
[03:56:55] <seb_kuzminsky> i changed it to point to www.linuxcnc.org/docs instead, because that's where the buildbot rsyncs the docs
[03:56:59] <seb_kuzminsky> seems fine now
[03:58:06] <Tom_itx> how was the 1st new website day received?
[03:59:49] <seb_kuzminsky> Tom_itx: pretty quiet, which i guess is good
[04:00:09] <seb_kuzminsky> i accidentally broke the automatic updating of our docs, but we just fixed it
[04:00:26] <seb_kuzminsky> so as of now there are 0 known problems with the new website, yay
[04:02:08] <mozmck> nice!

[15:10:19] <jepler> ugh several OOMs in dmesg

[15:14:37] <jepler> seb_kuzminsky: now do the *picture* of the dog with the caption 'it's a unix system...'
[15:17:39] <jepler> anyway, I added 2GB of swap space to the system
[15:17:53] <jepler> I'm reluctant to move it to a higher-specced virtual machine because it's a big bump in $$
[15:18:43] <cradek> did it have any swap before?
[15:18:45] <jepler> and unfortunately I need an education to know how to 'reduce max number of connections'. meaning mysql or apache?
[15:18:48] <jepler> cradek: no, none
[15:19:02] <cradek> surely swap will fix it just fine then

[15:29:17] <mozmck> jepler: I guess you did not use dreamhost for the forum because you didn't have access?
[15:31:58] <seb_kuzminsky> mozmck: i think it was partially that, and partially that jeff wanted a vps instead of a shared host, so we have more control over it
[15:32:12] <jepler> yes both of those are factors
[15:32:15] <mozmck> I see.
[15:32:32] <jepler> but the problems with shared access to the dreamhost setup was certainly a huge factor
[15:34:04] <mozmck> The kicad website had all kinds of issues on a vps, but then they were using confluence (java) for the site, and they could never give it enough memory to not crash.
[15:34:58] <seb_kuzminsky> i'm glad we didn't pick anything java-related for any of the new web thingys we just made

[15:47:31] <jepler> why, we all remember how the time sharing systems could support 131072 users on just 500 bytes of memory
[15:48:19] <jepler> but children today forget how we had to keep pushing the treadle to rotate that drum with 500 bytes of memory on it

[15:49:19] * seb_kuzminsky pats jepler
[15:49:25] <seb_kuzminsky> there there
[15:50:50] <seb_kuzminsky> there was a thing called swapd, that would add swap files when the system got low and remove them when memory pressure eased
[15:50:57] <seb_kuzminsky> i havent run it in years
[15:50:58] <jepler> yeah that was nuts
[15:52:31] <archivist> I just cannot understand why memory hogging code is regarded as good in any way
[15:53:34] <seb_kuzminsky> memory usage is often in the service of performance enhancement - ram is cheap, human-time is expensive
[15:54:32] <cradek> I don't think it's usually a choice/tradeoff made on purpose. it's just what happens when you don't particularly care about it.
[15:54:44] <jepler> minimizing memory usage requires careful analysis and is often put off until it becomes a critical and deep-seated problem in any software package
[15:54:45] <seb_kuzminsky> that could be too
[15:55:03] <cradek> it's not really considered "good", it's just that it's extra work to be careful about memory footprint

https://sourceforge.net/p/emc/bugs/449/, to wash the taste of html out of my mouth
[15:57:18] <jepler> we knowingly choose technologies with terrible memory properties, just because available RAM is usually big compared to what we imagine our program will require
[15:58:20] <archivist> our old Altos used 256 k per user iirc
[15:58:56] <jepler> consider this Python program to l = [random() for i in range(1024*1024)]
[15:59:12] <archivist> back when terminals were in RS232 around a building
[15:59:17] <cradek> seb_kuzminsky: yay a bug you can fix in one C file
[15:59:17] <jepler> it makes a Python list of 1048576 random floating point numbers
[15:59:25] <jepler> but instead of 1 memory allocation of 8*1048576 bytes
[15:59:39] <jepler> it does about 138MB of allocations
[16:00:39] <seb_kuzminsky> cradek: yeah, and the test is already 95% written
[16:00:52] <seb_kuzminsky> jepler: yikes

[16:01:52] <jepler> each double itself seems to take 24 bytes of storage, but also there are a lot of intermediate allocations that are made
[16:02:02] <jepler> .. plus the 8-byte pointer to it in the list
[16:02:15] -!- islander261 has quit [Quit: Page closed]
[16:02:56] <archivist> string processing is a bit funky in php for a similar reason
[16:03:03] <jepler> so besides the 32MB needed to store what would take 8MB in C, an additional 100MB is allocated and freed in the process of doing all that work
[16:03:41] <jepler> .. and that's ignoring the fact that my stats (which come from valgrind) are about calls to malloc() etc, and don't count the allocations Python does (it has a series of pool allocators)
[16:03:58] <jepler> and yet .. I love python
[16:04:06] <jepler> and in summary, that's why I think you can't do anything with 1GB memory anymore
[16:04:50] <seb_kuzminsky> i bet there's some python kung fu to make it more efficient, but i dont know what it is
[16:06:58] <mozmck> OOP != python
[16:08:01] <mozmck> gtk is object-oriented C (and would have probably been 100 times better if they just used C++ instead of re-inventing it all in C)

[17:41:15] <cradek> when I go to recent topics and then click on a thread, it shows me the first (oldest) page of messages in that thread. I can't find a setting that changes that. am I missing something?
[17:44:18] <mozmck> I'm sure there is a way to change that - it would be nice though.
[17:45:01] <mozmck> If there are multiple pages there will be numbers below the topic and you can click on the last number to go to the last page.
[17:45:11] <cradek> yeah I did see that
[17:45:27] <cradek> but ... I can't imagine doing the task of reading all new messages that way
[17:46:10] <cradek> I think "recent topics" is sorted the other way, with new on top of page 1
[17:46:15] <cradek> yeah
[17:48:08] <cradek> > Select default message ordering when viewing a topic. This setting can be overridden by user.
[17:48:17] <cradek> this is in the admin page
[17:48:29] <mozmck> interestingly, if I click on a topic that says there are new messages since I looked at the thread, it takes me to the first unread message.
[17:48:44] <cradek> oh, interesting
[17:48:56] <cradek> that would be less horrible
[17:49:48] <mozmck> I wonder where you override that setting?
[17:50:09] <cradek> there are a few preferences under profile / edit / update your profile

[21:36:17] <andypugh> cradek: Ever noticed how ideas can get simpler and simpler the longer you carr on not doing them?
[21:36:26] <andypugh> (carry on)
[21:36:29] <cradek> heh
[21:36:47] <andypugh> you know the draw-wire to resolver for absolute saddle position idea?
[21:36:53] <cradek> sure
[21:37:09] <andypugh> It became a 200:1 geardbox on the end of the leadscrew
[21:37:17] <cradek> cool!
[21:37:28] -!- JT-Shop has quit [Read error: Connection reset by peer]
[21:37:40] <andypugh> Then, it became a fine-pitched thread cut on the end of the ballscrew, and a worm-wheel on the resolver…
[21:37:50] -!- LikeVinyl has quit [Read error: Connection reset by peer]
[21:38:01] <cradek> ooh that's even better
[21:38:19] <andypugh> I wonder if it can get any simpler?
[21:38:35] <cradek> so the screw turns
[21:38:53] <cradek> the worm is really clever
[21:38:56] <andypugh> It just counts ballscrew revs, really
[21:39:23] <cradek> wouldn't the worm wheel have to be pretty big diameter?
[21:39:35] -!- JT-Shop [JT-Shop!~john@172.242.222.19] has joined #linuxcnc-devel
[21:39:35] <cradek> I assume your screw turns a lot of times over the travel
[21:39:42] <andypugh> About 120 turns
[21:39:53] <cradek> hmm
[21:40:13] <andypugh> If I use a 0.5mm circular pitch, then it’s all adequatelu compact
[21:40:33] <cradek> cutting a fine thread in a case-hardened screw seems hard
[21:40:34] <andypugh> Or 0.25 mod. That keeps it about the same size as the resolver diameter
[21:40:59] <cradek> you could make a sleeve
[21:41:03] <andypugh> I need to machine the ends anyway, and once you are through the hardening they machine quite well
[21:41:10] <andypugh> Or, indeed, a brass sleeve
[21:41:24] <cradek> oh sure, you could cut through and thread just the soft part
[21:41:38] <cradek> who cares what diameter it is
[21:42:12] <andypugh> I anticipate fitting it into the talstock-end support, but it might find a home in the drive-motor end. (less worry about thermal expansion having an effect at the motor end, as that is also the thrust-bearing end)
[21:42:52] <cradek> it sounds a lot like a threading dial
[21:43:16] <cradek> do any clever lathes do clever things for threading dials that could give you ideas?
[21:44:16] -!- JT-Shop has quit [Ping timeout: 265 seconds]
[21:44:51] <cradek> if you can get to the end of the screw and mount a pin off-center, you could make an awesome 120-sided geneva wheel
[21:45:10] -!- shaun414 has quit [Ping timeout: 240 seconds]
[21:45:17] <cradek> then it could advance nicely between indexes and be still around the index
[21:46:41] <andypugh> I wonder how small a 120-tooth geneva could be?
[21:46:48] -!- JT-Shop [JT-Shop!~john@172.242.222.19] has joined #linuxcnc-devel
[21:46:50] <cradek> probably not very
[21:47:18] <cradek> hey if you have a geneva wheel with a smaller but prime number of lobes, you'll still get individual discernable positions
[21:47:32] <cradek> I think
[21:47:55] <jepler> I was just thinking you needed two relatively prime ones so that you can discern p*q different positions
[21:47:56] <cradek> make 13 lobes and you'll get 10 turns but 120 positions
[21:48:29] <cradek> this is the coolest idea so far, but not the simplest
[21:49:41] <andypugh> In theory you could do it with just a resolver directly coupled to the screw and prime-ratio gearing to the motor, I think.
[21:50:56] <andypugh> Each motor-index can be made to happen at a different point on the screw
[21:51:06] <andypugh> No need for a geneva as such
[21:51:25] <cradek> yes maybe so
[21:52:03] <andypugh> I have just been trying out the motor and resolver in the core-box for the casting:
https://picasaweb.google.com/lh/photo/peSZLLJIqk5YimEhgYzJmtMTjNZETYmyPJy0liipFm0?feat=directlink
[21:52:41] <cradek> it's huge!
[21:53:10] <andypugh> Yes
[21:53:21] <andypugh> I am heartily sick of making patterns
[21:53:24] <jepler> https://youtu.be/WYcqJ5HdxA4?t=94
[21:53:51] <andypugh> Do you get to scroll back through the photos?
[21:53:59] <cradek> yes
[21:54:23] <andypugh> Back about 6 there is the pattern colection
[21:54:50] <cradek> that looks like a right pain
[21:55:17] <andypugh> All part of the fun.

[22:00:18] <cradek> wow
[22:02:36] <cradek> to be fair, you took out a resistor too
[22:02:44] <andypugh> I am not going to try to fit the DC PSU and 8i20 drives in there, and in fact the VFD is probably better placed somewhere else in the machine base
[22:03:23] <andypugh> The resistor is still mounted in the door
[22:03:26] <cradek> ah
[22:04:28] <andypugh> I could probably get the 8i20s in the door, but I am not sure I want to.
