<cr1901_modern> I need a powerpc machine... well, one I'm not using right now
<rqou> yeah, ppc is pretty good for being a "weird" platform to test things on
<rqou> non-x86, big-endian, and slow
<rqou> well, my machine is slow
<rqou> but still modern enough to have ethernet and usb and other fun interfaces
<cr1901_modern> It's used for my NAS, and I need to upgrade my NAS anyway, but I wouldn't mind using the old one for testing
<rqou> a ppc nas?
* cr1901_modern goes and gets the uname
azonenberg_work has joined ##openfpga
<rqou> ah, azonenberg_work: back from work?
<cr1901_modern> rqou: It's an APM82181
<rqou> oh. an actually embedded device
<rqou> yeah, i test on a ppc mac
<azonenberg_work> Yes but busy
<rqou> lol how are you still busy? :P
<rqou> it's friday :P :P
<azonenberg_work> I just upgraded my desktop to debian 9 from 8
<azonenberg_work> now i have to upgade vmware b/c my old vmware version isnt compatible with vmware 4.x
<azonenberg_work> then i have to go update all of my VMs
<azonenberg_work> patch day woo
<rqou> ah, sysadmin yak shaving
<rqou> just run sid, you get a minor version of this every day :P
<rqou> but yeah, friday is good for sysadmin-ing
<rqou> i should do some at some point
<azonenberg_work> also for some reason apt is derping out
<rqou> oh yeah, what's everyone's favorite server/vm configuration management tool? iirc whitequark and awygle had opinions?
<azonenberg_work> it resolves my mirror to an invalid IP address
<azonenberg_work> sits around and times out for a while
<azonenberg_work> then retries another IP and works
<rqou> yeah, i've seen apt do that too
<rqou> usually it's the mirror's fault or the local wifi ap's fault (broken ipv6)
<whitequark> rqou: ansible
<azonenberg_work> I have working IPv6, i just tested pinging to google
<whitequark> it's not my "favorite" exactly
<whitequark> but it's the least shitty one
<azonenberg_work> but i think it's trying to resolve an unroutable IP
<whitequark> it's still shit, of course, even people who like it admit htat
<azonenberg_work> or maybe use the wrong interface?
<rqou> azonenberg_work: i've seen the mirror itself have ipv6 issues occasionally
<azonenberg_work> i have like six IPv6 subinterfaces on this box
<azonenberg_work> and only one actually routes to the internet :p
<rqou> whitequark: opinions on chef or puppet?
[X-Scale] has joined ##openfpga
<awygle> Agree with ansible if that's the question
<whitequark> rqou: horrifying overkill
<whitequark> like uhm
<awygle> Puppet is a... What do I keep seeing on Twitter? Hell realm?
<whitequark> using chef instead of ansible is like using hadoop when you need a usb flash drive
<rqou> awygle: but cs162 likes puppet :P
<whitequark> puppet is just crap
<awygle> I set up puppet for research o
<awygle> *rescomp while I was there
<awygle> It's a nightmare
<rqou> cs162 set up puppet on vagrant
<rqou> most of the initial office hours were dominated by "vagrant doesn't work! how do i enable vt-x?"
<awygle> I am gonna be doing all this tonight too now that I'm back from the gym. Tonight is "awygle finally learns about docker"
<rqou> has docker ever fixed the "needs to run as root" issue?
<whitequark> no
<whitequark> (afaik)
<awygle> I seriously doubt it
X-Scale has quit [Ping timeout: 248 seconds]
[X-Scale] is now known as X-Scale
<whitequark> it was something fundamental
<rqou> oh btw, something that would be neat (but i don't have time to do) would be a rust rewrite of dnsmasq
<awygle> Isn't dnsmasq like, aggressively insecure?
<whitequark> huh?
<rqou> not aggressively so, but it had a string of sploits recently
<awygle> I feel like I hear about it all the time
<awygle> But I don't pay that much attention
<rqou> but i also want better support for ipv6, multiple subnets, and split-brain dns
<awygle> iirc I was sad it didn't do dnssec right, but today-me thinks that sounds like I was doing it wrong

<azonenberg_work> welp
<azonenberg_work> even NEW vmware needs a kernel patch to work on 4.13
<azonenberg_work> But at least it runs
<rqou> stop using vmware? :P
<azonenberg_work> rqou: This will most likely be my last vmware purchase
<rqou> i use qemu/kvm+virt-manager
<azonenberg_work> They removed the one killer feature i used heavily (unity mode)
<azonenberg_work> But short term i need to get my VMs running until i move
<azonenberg_work> Long term i'm going to build a dedicated KVM server for non-performance-critical stuff
<rqou> virt-manager is pretty garbage, but qemu/kvm works pretty well for what i care about
<azonenberg_work> i.e. OK to access over VNC/RDP
<rqou> apparently there's an issue with usb hotplug as usual
<azonenberg_work> Then the one thing i do in VMs where performance matters (gaming) will run natively on $WIFE's new desktop, once i buy it
<azonenberg_work> But i need one last copy of vmware until i have the time and budget to do that migation
openfpga-bb has joined ##openfpga
<rqou> whee, bot is back!
<azonenberg_work> yeah it runs on one of my vmware instances :p
<azonenberg_work> Hence being down while rebooting/patching the host and installing vmware
<azonenberg_work> My border router and file server are running old (but still getting security patches) OS versions
<azonenberg_work> i probably wont do more than critical patches on those until i move and get the new network up
<rqou> oh yeah, i'm slowly in the process of separating out the nas+build machine and the border router
<rqou> having them combined makes sysadmining _suck_
<azonenberg_work> Yeah i split my nas and border router recently
<azonenberg_work> well ok when i moved here :p
<rqou> because the requirements for both security and uptime are completely different
<azonenberg_work> i dont have a dedicated build box ATM
<rqou> e.g. border router - "security meh, uptime important"
<rqou> nas+build box - "security very important, uptime meh"
<rqou> my build box just runs on my nas
<azonenberg_work> When i move, the plan is to buy a new desktop
<rqou> good enough out of 10
<azonenberg_work> with extra pcie so i can put a 10g nic in it
<rqou> yeah, my nas already has that
<azonenberg_work> then move my current desktop mobo into a 2U rack case
<azonenberg_work> once i pull out the nvidia card, i'll have free pcie for a 10g nic
<rqou> i'm going to move the border router to a nuc that i got my parents to buy for me :P
<azonenberg_work> Then, until i get a 10g switch
<azonenberg_work> run point to point 10g from the desktop to the VM server
<azonenberg_work> 32GB of DDR3 should be enough to run all of my VMs
<rqou> it's a little awkward because there's only one ethernet port and so needs some vlan magic
<azonenberg_work> considering i will no longer be gaming in VMs
<rqou> fortunately thanks to US infra sucking, it's not likely i'll have >500mbps internet for a while
<azonenberg_work> I care a lot more about lan-to-lan performance than outbound
<azonenberg_work> My upstream is 50x10 i think
<azonenberg_work> But i saturate gig lan and will make good use of 10G once i have it
<rqou> same, hence a cheap NUC is good enough as a border router
<azonenberg_work> I have a 2U box with an i3 and minimal ram
<azonenberg_work> Close enouhg, but rack mounted
<azonenberg_work> and well when you have a lot of vlans
<rqou> but a nuc is smol and adorable and not unnecessarily 2U
<azonenberg_work> good lan-to-lan routing performance matters
<azonenberg_work> see, from my perspective
<azonenberg_work> awkward smol boxes
<azonenberg_work> that i cant rack
<azonenberg_work> pile up and get in the way
<azonenberg_work> i have rack space more than shelf space
<rqou> well, my cable modem can't be racked either
<azonenberg_work> i plan to make an adapter for mine
<azonenberg_work> honestly
<rqou> nor can the clusterf*ck of the wifi setup here
<azonenberg_work> even if its just a rack shelf
<rqou> also, if i had a rack, the cable modem+nuc still fit on one shelf
<azonenberg_work> but we'll see what kind of modem i get from comcrap when i move
<azonenberg_work> idk if i'll be able to keep this one on a new address
<rqou> you can just buy your own modem
<rqou> btw, i did mention the weird split network setup i have here, right?
<rqou> there's _two_ switches here
<rqou> one ebay datacenter switch and one meraki switch
<rqou> the problem is that they're on opposite sides of the doorway, so there's a pile of spaghetti connecting them
<rqou> and no, they can't be combined for two reasons
<rqou> 1) one of the cables going into the meraki switch isn't long enough to reach the other switch
<rqou> 2) the meraki wifi ap must be on the same side as the ebay datacenter switch because the signal there is better
<rqou> 2b) the meraki switch cannot be eliminated because it injects PoE for the AP, and we don't have a power brick for the AP
<rqou> network planning is hard :P
<awygle> Get a longer cable. Or get a reel of cat 6a and make one
<awygle> My "network" is a WNDR4300 at the moment
<awygle> Also I need a new laptop
<azonenberg_work> And get a poe injector
<whitequark> christ rqou
<awygle> Hey whitequark, was your Twitter saga about the XPS13 a recommendation or an indictment?
<whitequark> awygle: recommendation
<awygle> Noted, thanks
<whitequark> (of the laptop, anyway, not the repair service)
<whitequark> it has kept together *far* better than I expected
<whitequark> in fact I almost never notice that it has a totally blown hinge
<awygle> Also thanks for running your irc logs btw. A very useful service on which I am nothing but a drain.
<whitequark> I was quite expecting it to fall apart like the cheap stamped aluminium crap that passes for cases these days but no
<whitequark> I don't know how they did it, but it's thin, lightweight *and* sturdy
<whitequark> the bottomcase is nicely machined from a single aluminium billet, not stamped
<whitequark> the topcase is some carbon fiber wizardry, I don't pretend to understand it but it has not kept cracking after the initial incident
<whitequark> it just has a fissure in it and ... that's it
<whitequark> so, like, whatever? I'm not sure I even want to spend money fixing it, it's good enough
<whitequark> there's also a complete disassembly manual from Dell so even if I do want to remove the thirty seven or something screws that hold the keyboard in place I won't have to go to ifixit
<awygle> That sounds great, I am very hard on laptops. I'd probably get the 15 tho...
azonenberg has joined ##openfpga
<whitequark> sure
<whitequark> 13 is tiny
<whitequark> that's why I love it
<whitequark> awygle: also do notet
<whitequark> 13 has such a small border around the display that it's almost 15" in the *effective* display size
<awygle> Yeah I saw that in the ad copy. My current laptop is 17" and weighs like eleven pounds so it's a question of how small vs how light I guess
<whitequark> ahh
<whitequark> yeah then 15 is for you
<whitequark> the ad copy doesn't lie btw, the screen really is glorious
<whitequark> it rivals smartphone screens in densities
<whitequark> it's honestly one of the best things I have laid my eyes on
<whitequark> (I have the QHD one, so 3200x1800)
<whitequark> I have all fonts set to render at 277dpi so I only have a little more text on the screen but it's a pleasure to observe it
<awygle> IPS too, that's a must have
<awygle> Does the QHD need the GTX?
<whitequark> no, I have Intel only
<whitequark> everything is super smooth with KDE and Chromium
<whitequark> you do have to use browser with GPU accelerated rendering though
<awygle> Tempted to get the GTX anyway... I don't really need it it's just habit.
<awygle> Well this looks pretty sweet. Probably my Christmas present to myself. Thanks for the recommendation
<whitequark> awygle: oh btw do check the reviews on your specific model
<whitequark> they have a few different variants and I think one of them had issues
<whitequark> pretty obvious ones so note the model number and google and that should do it
<awygle> mk, wilco
<awygle> goddammit. i just locked myself out of this VM in the dumbest way. forgot -a on usermod, removed self from sudoers.

<azonenberg> awygle: Been there done that
<awygle> It is of course the one VM that I apparently didn't record the root pw for. Thank goodness for ansible.
<pie_> anyone know anything on/what i can read about designing fault tolerant hardware?
<rqou> hmm azonenberg: in your gp4 code, how "first-class"/"designed-in from the start" is error reporting?
<rqou> e.g. if a design is unrouteable, can you track down what wires/nets were not successfully routed?
<rqou> *wires/nodes
<rqou> and then can that be tracked back to source code?
<azonenberg> Off the top of my head i dont remember
<azonenberg> I know it lists the nodes it cant place
<pie_> "Fault Tolerant Computer Architecture" - Daniel J Sorin
<awygle> pie_: I know a fair bit about it, ask me in like 9 hours.
<pie_> awygle, oh cool
<pie_> i dont have any specific questions just wonderin
<pie_> thanks
