brycecSo only $$$ not $$$$ ? [09:25]
m0undsyup
less than $1500
that's better than $7500 for sure
[09:27]
brycecm0unds: So what was it - capacitor? [09:28]
m0undscapacitor, condenser fan motor
capacitor is barely within spec, so i told him to r&r - also, he saw the leak the previous tech noted on the prev inspection and i asked him to fix that
so the bulk of the cost is the labor and refrigerant since they have to pump it out to fix the leaky schrader valve
[09:35]
.... (idle for 19mn)
brycecHeh I often think I should do HVAC work
"If it's not the compressor, it's a cap. if it's nto a cap, it's the condensor."
[09:55]
m0undshvac could be fun
i like trade stuff
i think if i ever get sick of doing IT-related things, i'd probably look into going to trade school for electrical or hvac or something
[09:57]
brycecAgreed. And some days, it's more appealing than others... [09:57]
m0undsyeah [09:58]
brycecThough, I used to live in Phoenix, and doing HVAC work there would suck. [09:58]
m0undshahaha
yeah, for sure
climates where people shouldn't be living = no
hahaha
cold or hot
[09:58]
brycecI've come to enjoy living up north
Snow etc
[09:59]
m0undsyeah
i get snow here because of the elevation, but not much rain
[09:59]
brycecToday's high is 83, then it's going to drop 10-20 degrees over the next couple of days. [10:00]
m0undswhen my wife finishes her work contract, we'll probably look into moving somewhere else [10:00]
brycecAlso: cold climate == excuse to run servers in the house [10:01]
m0undshahaha [10:01]
brycecAt least 50% of my winter heating was from exhaust heat. [10:01]
m0undsnice
i had to shut down my storage server because it's been shot hot w/no functioning AC
shot? so hot.
[10:01]
brycecAt times, I had to leave my office window open to cool it down even. [10:01]
m0undsugh
hahaha
[10:01]
brycecbrycec felt weird to have windows open while snow fell
lol I understood "shot" I know a guy who abbreviates that way, pretty good -> pgood
[10:01]
m0undsyeah, i've done similar - just put cardboard in the return in my office/computer room
but i said shot hot, haha
so hot hot i guess
[10:02]
brycecatm machine
nic card
etc
[10:02]
m0undsi just want winter to come back [10:03]
brycecNah didn't even need directed airflow - was just cooling down the whole room. (Also, servers were opposite of the window)
Me too :)
Not that summer is bad, but summer = bugs
Though, at least in the summer, my fingers don't get cold and stiff and make typing nigh-impossible[10:03] <m0unds> oh, i blocked my return because i didn't want the furnace pulling in chilled air (when i had my window open, it dropped room temps to 60 or lower)
[10:03]
m0undsall the bedrooms in my house have ducted returns [10:04]
brycecI've since moved my servers out from the office (second bedroom) into the living room (big room, vaulted ceilings) so lots of airspace [10:04]
m0undsnice [10:04]
brycecI have no central heating/cooling :P [10:05]
m0undsour downstairs runs pretty cool when we have AC - typically 70 downstairs and 80 upstairs
without AC, 85 downstairs and 90+ upstairs
haha
[10:05]
brycecYeah. I'm not a fan of the noise (bad pun unintended), but I'm not in the living room much. And soon, I hope to have that drive shelf setup to only come online as-needed.
(Xserve RAID - those things are not quiet...)
[10:06]
m0undsright [10:06]
brycecOne of these days, I'll get things scripted to power it on, mount/import it, transfer backups over, then unmount/export and power it back off
That will be COOL
Near-side cold storage, sorta
[10:07]
m0undsi've never worked with xserve stuff before [10:08]
brycecAnd you're not likely too since it's been discontinued :P
Apple carried on the name for their servers, but dropped the RAID shelf line
[10:09]
m0undsonly one person i know worked w/their server gear in any capacity [10:10]
brycec(Talk about loud - the xserves themselves are deafening) [10:10]
m0undsand it's because his predecessor was crazy about apple stuff and believed you couldn't use anything but apple servers on a network with any other apple devices
my supermicro stuff is pretty loud - 4u and 1u chassis'
the 1us have those tiny little 40mm or 30mm fans that just howl
[10:10]
brycecPWM driver is broken too, so the turbines are running 100% at all times
Fortunately, that xserve is in the warehouse at work and doesn't bother me :)
[10:12]
m0undsyuck
do you run OSX on your storage server?
[10:12]
bryceclol no. At home, my storage stuff is FreeBSD
and the xserveraid is just a disk shelf for me (JBOD)
The xserve g5s I talk about I keep at work as hobby stuff, because I have a soft spot for ppc, sparc, and mips
[10:16]
m0undsgotcha
jbod disk shelf for zfs or something?
we're budgeting for a pair of ixsystems storage servers next year
need to get separate stuff for incident/evidence backup
[10:25]
brycecYeah, ZFS on it
<3 ZFS
[10:26]
m0undsyeah, good stuff [10:26]
brycecThe aforementioned server has has 20 drives in it, plus a fibrechannel card connected to the xserveg5, providing me with something akin to hot and cold storage pools [10:27]

KILLALLHUMANS01KILLALLHUMANS01 wonder what the heck... where did that brycec fellow go?
up_the_irons: is this your doing? Have you killed my kvm/qemu process?? I can't even hit the VNC
KILLALLHUMANS01 angrily blames up_the_irons
[14:44]
up_the_ironswhy would i do that [14:48]
KILLALLHUMANS01I dunno
up_the_irons: Before I reboot - is there anything you can do to see 'why" it seems to have killed itself?
(kvr07)
KILLALLHUMANS01 ought to have some external monitoring of his external monitoring host
(well I have notifications, but not usage)

KILLALLHUMANS01Looks like setting up one's own looking glass is pretty easy with an OpenBSD box/VM. http://menari.eu/post/13924017079/creating-a-looking-glass-with-openbgpd
KILLALLHUMANS01 idly waits for all humans to be killed, and reads up on ideas that were proposed in #arpnetworks
And an example of what it looks like http://lg.onvoy.net/cgi-bin/bgplg

up_the_ironsbrycec: tnx for the route reflector stuff, looks pretty easy to set up [16:33]
brycecAgreed, though there's a lot about BGP I don't yet know
But simply seems to be a read-only replication stream from your router
And then a little bgplg/bgpctl glue
Keeps your route server "clean"

mercutioi did mention the openbsd looking glass was simple before :)
openbsd has dropped apache out of base though, so any old tutorial is probably not relevant
err 100% relevant
[16:57]
brycecIt's pretty easy to hook up a CGI script to nginx though. I'm sure someone like up_the_irons doesn't need the hand-holding, just the general ideas [16:58]
mercutioheh
i've never actually touched nginx yet :)
[16:58]
brycecbrycec <3 nginx [16:58]
mercutioi suppose most people hav enow? [16:58]
brycecI used to <3 lighttpd, then I met nginx [16:58]
mercutioi still don't know how it's better than lighttpd [16:58]
brycecI think Apache is still 90% of the global market
nginx and lighttpd are pretty similar, especially compared to the likes of Apache
Though I find nginx to be smoother and easier (faster, more descriptive config linting for instance)
Mostly, I stick to nginx (over lighttpd) because it's what's in base
[16:59]

mercutiopkg_add lighttpd is pretty simple though :) [17:10]
brycecIt's less about "ease" and more about what OpenBSD has put their weight behind
"endorsement" if you will
[17:24]
m0undsis lighttpd still actively developed, or is it down to just security fixes at this point?
m0unds also loves nginx

brycecIt's hard to tell... one the one hand, their last "preview release" (1.5.0) was 4 years ago, but they have also been slipping in some features along with the bug fixes (see http://www.lighttpd.net/2013/9/27/1-4-33/)
(the release before that was November 2012)
[17:45]
mercutioit's not very active
neither was apache 1 though :)

i guess, by contrast, nginx is extremely active
[18:56]

mercutiodoes it have tcp fast open support?
it's easy to add if it doesn't
it's abuot the only feautre i want to see atm :)
i hacked it into lighttpd, and i could notice the difference with cacti
but it's linux only, and chrome has buggy support of it.

brycecmercutio: Yes, it's stock. http://nginx.org/en/docs/http/ngx_http_core_module.html "fastopen=" [20:15]
mercutiocool
yeah it's kind of a newish thing
with hardly any adoption other than google it seems
[20:15]
brycechttp://hg.nginx.org/nginx/rev/692afcea9d0d Apparently requires a recent Linux kernel [20:16]
mercutiobut the same concept can help more than just http
it could make ssh login quicker etc too
not very recent i think
i was playing with it first a year or two ago
i did find something curious, some international stuff didn't benefit as much as it should for larger files
i think it's some kind of automatic bandwidth shaping stuff or such
like short page with 160 ms rtt was like 160msec
err was like 170 for the second
longer pay with or without tcp fast open averaged more ilke 120msec or such dfiference
i nede to test again :)
i was trying to modify my curl implementation to work with smokeping so i could test properly.
