mithroMorning people02:05
CarlFK[m]mithro: Ohio LinuxFest is an LCA like event in about a month.  Choco31415  want's an Opsis to record 1 track.  What can you say about buying them from Numatto?02:12
mithroCarlFK[m]: Waiting for them to get back to me02:12
mithro(Numato that is)02:13
CarlFK[m]mithro: ok.02:13
mithroCarlFK[m]: So what is your next event?03:00
CarlFK[m]mithro (IRC): Chris's python in November03:06
CarlFK[m]mithro: do you have more Tomus ?03:06
CarlFK[m]guy here wants one.03:07
mithroCarlFK[m]: Is Chris' Python thing isn't PyCon right? It's more like PyOhio03:07
mithroCarlFK[m]: Yes I have more, if he sends me a pull request I'll mail him one03:07
mithroxfxf: We aren't doing live streaming right?03:18
mithroCarlFK[m]: How do I "build" the current video machines? Are they debian based now?03:18
mithroCarlFK[m]: I heard something about creating a USB stick?03:20
CarlFKboth pxe and usb build the same thing using the same preseed and ansible stuffs03:21
CarlFKpxe is easier to hack on - you edit/save files on the server, reboot the pxe client box and see what happens03:21
CarlFKthe usb stick is easier to just do - use your laptop to create it, pull it out, plug it in, boot.. get a box03:22
mithroCarlFK[m]: How much space do I need on the usb stick?03:23
CarlFKmithro: 1 or 2 gig03:23
mithroI'm trying to setup these USB sticks I got with Ubuntu installer + the Xilinx FPGA tools03:24
CarlFK[m]mithro (IRC):
tpbTitle: video-stack-deploy/scripts at master · CarlFK/video-stack-deploy · GitHub (at
mithroCarlFK[m]: Is the USB stick setup for an individual machine, or?03:26
CarlFK[m]mithro: so the simple answer is: depends on what ansible roles you define for that host name03:27
mithro"where to get preseed file" -- what does this mean?03:27
mithroCarlFK[m]: And you complain about my docs :-P03:28
CarlFK[m] the video box installer is not self contained - it expects to wget config files from somewhere - like your laptop over the lan, or a web server whereever you want03:28
mithroOh - do you have any plans to make it self contained?03:28
mithroI'm sitting in a hotel room with rather crappy internet access03:29
CarlFK[m]not really03:29
mithroI'm actually trying to setup 3 laptops with the HDMI2USB toolchain to let people hack on MicroPython for FPGA stuff03:29
CarlFK[m]the 'problem' with making it self contained is how quickly it becomes out of date03:30
CarlFK[m]the usb stick is more to boot strap the process - but I do make good use of squid to cache the .deb s which is most of the traffic03:31
mithroCarlFK[m]: I'm okay with rebuilding the USB stick frequently, like 30-40 minutes before using it - just that once I have a stick I don't need internet access on the machine which I'm imaging would be nice03:32
CarlFK[m]mithro (IRC): it is doable - but I don't see anyone doing it anytime soon03:34
mithroCarlFK[m]: Is the image debian based now?03:34
mithropaddatrapper: ping?03:34
CarlFK[m]another sort of - there is support for ubuntu, it also uses the same files, but i stopped paying much attention to it a few weeks ago03:35
CarlFK[m]mithro: if you are interested in building machines in your hotel room today:   (assuming one of them has some sort of linux on it..03:37
CarlFK[m]apt-install squid-deb-proxy  on it03:38
CarlFK[m]git clone my repo03:39
CarlFK[m]either figure out how to poke the squid config to allow it to cache files served up by the same box....03:39
CarlFK[m]or I can tell you what to poke in the pre-seed file03:40
mithroI think I'll just ignore that idea for now and just setup stock ubuntu03:47
CarlFK[m]how are you going to setup ubuntu with poor internet?03:48
CarlFK[m]oh, you have a stick.. that.03:48

CarlFK[m]mithro (IRC): the tail of the os install calls

CarlFK[m]or you can run ansible from your laptop against a fresh OS install that has sshd and keys03:59

Choco31415Carl: It's noon over here, but close enough!12:21
CarlFK[m]Choco31415 (IRC): mithro said "waiting to hear from Numato"12:21
Choco31415Carl: Very weird of me. I checked the logs, but somehow skipped the first 5 lines. -_-12:22
Choco31415Is there some way to know when Numato replies to mithro?12:26

paddatrappermithro: thanks to olasd I have the milkymist board to work on16:58
Choco31415CarlFK: When you were recording PyOhio, did you separately save the live/presentations feeds, or did you mix then save them?18:18
CarlFKmix and save18:25
CarlFKlow on my list is... (copy from #voctomix...18:25
CarlFK[m]...if you are looking for new stuff to hack on (which then helps tests the core stuff)   I would like to see sources being saved18:26
Choco31415So that last quote is saying it would be nice for Voctomix to support saving sources, in addition to the mix, but doesn't?18:33
CarlFKsomething should save... I expect it will be the client, not the mixer18:47
tumbleweedis it known that input0 on opsis doesn't work?18:48
CarlFKtumbleweed: mine worked on that super new build18:48
CarlFKtumbleweed: need me to dig mine up?18:48
CarlFKps, I found the small case I was going to give you.  whooops.18:49
