12:50 AM hazzy-lab1 is now known as hazzy-lab
09:54 AM seb_kuzminsky: are all thoes "Spam is not permitted on freenode" and "Spam is off topic on freenode" killed messages indicative of continuing spam storm?
09:59 AM cradek: sure seems so
10:00 AM cradek: guess they're joining here but not talking
10:13 AM hazzy-lab: seb_kuzminsky: Yes, spam is still flowing fast and free in other some other channels, 74 new spams in #pyqt since I last checked the chan at 3 am :(
10:14 AM hazzy-lab: This is one of the worst bouts we've had I think, normally it seems to get shut down pretty fast
10:20 AM * JT-Shop didn't even know there is a #pyqt channel
03:33 PM jepler: cradek: the spam bots aren't succeededing in sending messages to #linuxcnc(-devel) because unregistered users don't get "voice" due to a channel mode change I made yesterday
03:34 PM KimK: jepler: And thanks for that!
04:10 PM cradek: thanks for clarifying that. I thought that was what was going on, but my irc client says the channel is just +t so I wasn't sure.
04:11 PM cradek: but I think chanserv has layers of stuff beyond my wildest dreams
04:14 PM hazzy-lab: seems like the spam is staring to settle down elsewhere as well, ops are taking control
04:21 PM andypugh: pcw_mesa: I have just had the funny 7i73 MPG counts thing again.
04:23 PM andypugh: I have turned on enable_raw for next time, but I am not sure that we will be able to log it, as it is smart-serial data so I don’t think it will be the only thing in the register, and we would have to work out where it was in the register.
04:34 PM jepler: cradek: in irsii "/mode -q" will show you the 'quiet list' of the channel you're in.
04:45 PM andypugh: jepler: Do you have excel, or equivalent
04:45 PM andypugh: (Can you look at some numbers?_
04:46 PM andypugh: There is a definite repeating pattern to this wierd MPG output, it looks a bit like Gray-code, but bot exactly like gray-code, and it looks a bit like reversed binary.
04:46 PM andypugh: http://www.filedropper.com/7i73
04:47 PM andypugh: This is an occasional problem with the Hostmot2 MPGs.
04:47 PM andypugh: Power down and restart and it works normally.
04:49 PM jepler: for those who drink the google kool-aid https://docs.google.com/spreadsheets/d/1t0unn2YhZsoAF3ktPAc45N0rPLglTOPENb9uvYnkTMs/edit?usp=sharing
04:49 PM andypugh: It’s quite pretty, isn’t it? If your axes are not dancing about in sympathy with it.
04:53 PM andypugh: The MPG is handled by this code:
04:53 PM andypugh: https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/drivers/mesa-hostmot2/sserial.c#L2040
04:54 PM andypugh: bitlength is 8, graycode is false, nowrap = 0,
04:57 PM jepler: nothing has leapt out to me
04:57 PM jepler: at me?
04:58 PM jepler: maybe graycode is being corrupted in memory to true and it does something supa-weird until restart
04:58 PM jepler: afk
04:59 PM andypugh: It isn’t _exactly_ gracode, though.
05:00 PM andypugh: Though I haven’t tried graycode-converting binary.
05:07 PM andypugh: Aha! It is exactly the same pattern as you get when graydecoding straigh binary!
09:15 PM Tom_itx is now known as Tom_L
