pedjathis looks pretty straightforward (gpu pass-through on Ryzen) https://youtu.be/aLeWg11ZBn012:04

john_cephalopodahttps://lut.im/e9hckExnj3/A5U0hwpl1Hoys3L9.png13:27
john_cephalopodaAt least Nvidia is welcoming to dust ;)13:27
tsaopAMD seems the future13:38
tsaoptheir work on open source video drivers is shaping up really good13:38
tsaopLet's hope they can refactor their DC/DAL code for it to be merged into the mainline kernel13:38
*** Kruppt has joined #crux14:09
pedjait should land in 4.1414:11
john_cephalopodaThe only reason why I don't get an AMD is, because my computer is too new.14:12
tsaopI hope so14:12
john_cephalopoda4th gen intel, fast enough for my stuff.14:12
pedjawell, mine Core2Duo is 'fast enough' for most of the stuff. only 4G of RAM is a bigger issue :)14:15
john_cephalopodaI rarely use all of my RAM. When I do, it's either Chromium or some homework for university where I have to mess with giant point clouds.14:20
pedjapoint clouds? as in lidar data or?14:27
pedjalike these http://opentopo.sdsc.edu/lidar14:32
john_cephalopodapedja: 3d laser scanners.14:50
john_cephalopodaLike RIEGL.14:50
pedjayou get to play with some expensive toys :) nice14:55
*** sonophilia has quit IRC15:04
john_cephalopodapedja: Well, the professor plays with expensive toys :þ15:13
DaViruzi sometimes run a leica 3d laser scanner at work15:26
DaViruzthe software we use is god awful15:26
DaViruzor rather a laser tracker15:26
*** heroux has quit IRC16:12
john_cephalopodaDaViruz: What do you do with the software?16:16
john_cephalopodaDisplaying point clouds?16:17
john_cephalopodaThis toolkit is pretty cool (and open-source): http://slam6d.sourceforge.net/16:17
DaViruzmostly analysis of industrial machinery16:18
john_cephalopodaProvides tools for displaying point clouds (multiple different formats), doing registration, normal calculations, etc.16:18
john_cephalopodaDaViruz: Small-scale laser scanning for damages etc. or on a larger scale?16:19
*** http_GK1wmSU has joined #crux16:19
DaViruzanything from a few centimeters to a few hundred meters really16:19
*** http_GK1wmSU has left #crux ()16:19
DaViruzwe don't usually have very many points though, a couple of hundred at most16:20
john_cephalopodaThat's not much for a 3d point cloud :þ16:20
john_cephalopodaSo you are measuring out that machinery?16:22
DaViruzit's because it's a tracker and not a scanner. each individual point has to be measured separately with a reciever prism16:22
DaViruzmostly it's alignment checking. making sure rails are paralell, straight and level and such16:23
john_cephalopodaOh, phase-shift16:24
john_cephalopodaThe focus of the lecture I had was more towards scanning buildings, mapping interior areas and doing airborne and mobile (e.g. from a car) laser scanning.16:26
john_cephalopodaThe accuracy isn't perfect, but it's usually enough for the task.16:26
john_cephalopodaBefore, I have also worked on combining point clouds from stereo cameras and the point cloud from the Kinect 2.16:28

tsaopmedia portrayal of deep/dark web is funny18:20
tsaopthey just show a guy with a hoodie pressing keys at a pc where the matrix screensaver is running18:20
tsaopalso they showed some wireshark and an ubuntu gnome-terminal session where a shutdown message was visible18:21
dbrookethere's an app for that - http://blog.dustinkirkland.com/2014/12/hollywood-technodrama.html18:34
dbrookealso avaiable for docker18:34

pedja"I just finished eating this delicious vegan roast lamb (the lamb was a vegan, so it counts, right?"21:20
jaegerwhew... reassembled my GTX 980Ti back to factory air cooling... hope it still works22:01
joacimwas pretty nervous when i took my r9 290 apart22:02
joacimsince the paste was really sticky22:02
jaegerYeah, I know the feeling exactly22:02
joacimwas wondering if something was glued or fastened with adhesives22:02
jaegersadly one of the studs on my water block broke... and to be honest I'm kinda tired of watercooling in the mITX box. It's a lot of work22:03
joacimstill got a block for it tho, and im meaning to get a watercooling kit22:03
jaegerI'm a big fan of EK's stuff, for what that's worth22:04
joacimyeah, its one of those things i dont believe, when enthusiasts tell me it is really easy and no effort =)22:04
joacimlike hackintosh and other stuff too, i get sceptical when im told something is easy and requires no effort22:04
joacimwant a good deal on the kit, since i paid only 20 dollars or so for the gpu block22:05
jaegerI would say it's not *complicated*22:05
jaegerIt does require some planning and in a mini-ITX case, quite a bit of effort22:05
jaegerhackintoshing is very easy if your hardware is supported. I've done that a few times22:06
joacimyeah. coming here taught me the difference between simple and easy22:06
jaegerNothing that's operating out of default spec (such as hackintosh or watercooling) is "no effort", though22:06
joacimsomething i find frustrating when talking to "normies". since to a lot of people, simple and easy is one and the same22:07
joacimthey often are22:08
joacimare you pulling out all the watercooling gear22:11
joacim?22:11
jaegerJust finished doing so, pretty much. GPU was the last part22:11

teK_apparetly, udev still has race conditions renaming NICs, btw22:31
teK_eth0 => enp4s222:32
teK_eth0 => enp0s2522:32
teK_for two differnt NICs22:32
teK_:P22:32
teK_on another machine, it did this:22:33
teK_eth0 => eno122:33
teK_eth1 => rename322:33
teK_hihi..22:33
teK_I replied, that I way prefer the old racy behaviour with net.ifnames=0 ;-)22:34
joacimnot sure if i see the logic behind the enp?s?? names22:38
*** chinarulezzz has quit IRC22:53
jaegerin terms of why to do it or how they're determined?22:55
john_cephalopodateK_: Isn't the naming scheme of wifi interfaces based on the position they are installed in?23:03
john_cephalopodateK_: For example, lspci shows "04:00.0 Network controller: ..." and my card is renamed into "wlp4s0".23:04
joacimhow they're determined23:05
joacimbut yeah. the location makes sense23:05
jaegerhttps://github.com/systemd/systemd/blob/master/src/udev/udev-builtin-net_id.c#L20 if you want the specifics23:05
jaegerso enp4s2, to use teK_'s example, is an ethernet interface in slot 2 of pci bus 423:07
pedjaLeap has interface renaming disabled by default, iirc, which is interesting23:08
timcowchipLeap? isn't that Suse?23:08
pedjayes23:09
timcowchipthat's what I'm using, 42.323:09
pedjaI have a Leap VM to play with, and TW on a netbook23:10
timcowchipI play with Crux in a vm23:10
timcowchiptumbleweed is nice too23:10
pedjaagreed, even when it rolls just too damn fast sometimes, so there is ~400 package upgrade waiting for me when I power up the netbook :)23:13
pedja900, when they switched to gcc-7.x, so there was a mass rebuild23:14
pedjaI am thinking of wiping it and putting Leap on it, too.23:15
pedjait's an old machine, so I don't actually need the latest and greatest on it, hw support wise23:17
pedjathe only issue I have is that Xfce is somewhat broken on a 10' screen23:18
john_cephalopodaAn advantage of renaming is, that you can simply do lspci and see directly which interface your data goes to.23:19
pedjabut E19(?) is *fast* on it23:19
john_cephalopodaMaybe not a priority with normal desktop PCs but very nice with switches.23:19
joacimreminds me of the hdd names certain unix like systems use. names based on the controller and channel23:20
jaegerwoot, skylake i5 box is resurrected23:33
joacimit is your games computer?23:34
joacimbeen wondering what you use your different computers for =)23:34
jaegerThe skylake i7 is my main system, I use it for most things including games23:35
jaegerThe i5 is a mini gaming system23:36
jaegerThe ryzen box is a mini whatever system. Can game but doesn't have as powerful a GPU in it as the other two23:36
jaegerI have a baby canyon NUC i3 as HTPC23:36
jaegervarious raspberry pis23:37
joacimheh23:38
joacimi have a hard time giving much attention my other computers.23:38
joacimit's mostly my mac mini and ryzen machine that gets the most use23:38
jaegerI definitely don't use them all all the time23:38
jaegerMy skylake i7 is by far the most used23:39
joacimbut i've been meaning to transfer everything i do on my mac over to the ryzen machine.23:39
joacimnot sure if the old i5 machine should be for games or as a random as needed server tho23:40
joacimdont even know what to do about my rpi. it's just sitting there23:41
joacimbought a small gpio powered ips screen for it =)23:42
jaegernice23:44
jaegerhrmm... my ryzen box rebooted itself during the firefox build tests instead of just segfaulting this time23:45
joacimyou build with it often?23:48
jaegerWell, I haven't had it all that long so I can't really say yes23:49
jaegerBut I've run a lot of build tests on it to see if it's stable (it's not really) and chart times23:49
jaegerIt's one of the systems I used for http://jaeger.morpheus.net/misc/llvm.png23:50
joacimi havent noticed any instability on mine, but i havent really built much with it either23:51
joacimjust the regular updates once in a while23:52
jaegerI was able to build llvm 80 times without a problem. Firefox, on the other hand, not so much23:54
